Control system for apparatus for taking out molded product that detects collision based on torque
There is provided a control system for an apparatus for taking out a molded product, the apparatus performing appropriate operation when a collision occurs while a servo system control section is manually operated. When a collision detection section outputs an operation stop command, a deviation clearing section performs clearing operation to bring deviations in a servo system control section to zero with the servo system control section kept on. Positioning is completed as the deviations are brought to zero, which enables operation to be performed again. When a retracting operation is performed after the operation is stopped, servomotors are operated according to an operation command, which allows smooth retraction from the collision state.
Method for manufacturing gas cylinders
Disclosed is a method for manufacturing gas cylinders. The disclosed method for manufacturing gas cylinders comprises: a) a step of producing a liner using a liner blower machine; b) a step of applying an adhesive to the threads of the produced liner; c) a step of coupling a bushing to the threads of the liner; d) a step of leaving the liner having undergone step c) for 30 minutes to 2 hours at room temperature so as to naturally harden the adhesive; e) a liner-flaming step of heat-treating the outer surface of the liner with plasma; f) a step of coupling a shaft to the liner; g) a winding step of mixing multiple fiberglass strands with a resin and a hardening agent, and wrapping the mixture around the outer surface of the liner; h) a dry-hardening step of drying the cylinder made of the composite material and having undergone the winding step for 70 to 90 minutes at a temperature of 70 C. to 90 C.; i) a cooling step of leaving the cylinder made of the composite material for 15 to 40 minutes at room temperature so as to lower the surface temperature of the cylinder having undergone the dry-hardening step to a level of 35 C. or lower; j) a step of separating the shaft from the cylinder made of the composite material; k) a step of assembling a valve to the bushing installed in the cylinder made of the composite material; and l) a step of checking the state of the gas cylinder including the cylinder made of the composite material.
Automated rubber molding and de-molding
Molded rubber objects may be molded and de-molded by defining both a desired final form for the molded rubber object and a tab extending from the final form of the molded rubber object using a cavity in a mold. Rubber pellets may be dispensed in predetermined amounts at desired location(s) within the cavity to provide the rubber needed to form the molded rubber object. Heat and pressure may be applied to the mold to cause the rubber pellets to fill the cavity defining both the desired final form of the molded rubber object and the tab. After the heat and pressure has been applied, a gripping device may grasp the tab and move the tab in a direction and with sufficient force to peel the rubber object from the mold cavity. If desired, the tab may be removed from the molded rubber object.
Mould for Producing a Fibre Composite Component
A tool for producing a fiber composite component includes at least two tool portions which have partial cavities and which are moved together in a production position in such a manner that they form a cavity, in which cavity the fiber composite component is produced. Associated with at least a first tool portion there is a retention element which retains the fiber composite component produced in the first tool portion when the tool portions are moved apart after the production of the fiber composite component.
Molding apparatus for grp door skin
A molding apparatus for a GRP door skin is provided. The molding apparatus is configured to form a GRP door skin of a completed product by molding a GRP door skin in a forming mold, and inserting the formed GRP door skin into a trimming removing part through a robot.
Apparatus for taking out molded product
There is provided an apparatus for taking out a molded product that facilitates setting of a user-set lower limit value while maintaining on-off control. A negative pressure control portion includes a determining portion for determining a pressure valve resumption time period that is used to resume a suctioning operation such that an inflection point does not become lower than a user-set lower limit value. The negative pressure control portion continuously performs an off operation, which is performed to keep a pressure valve closed until the pressure valve resumption time period elapses after the suctioning operation is stopped, and an on operation, which is performed to open the pressure valve and keep the pressure valve open until a negative pressure reaches a stable value or an upper limit set value, until suctioning of a molded product is canceled.
COMPRESSION MOLDED DOUBLE WALL BLOCKS FOR A PALLET AND ASSOCIATED METHODS
A compression press is provided, comprising: a frame; a movable lid carried by said frame and having an opening extending therethrough; an enclosure carried by said frame and comprising a core movable between a retracted position and an extended position, with said core aligned with the opening in said lid; a first hydraulic stage carried by said frame; and a second hydraulic stage carried by said frame and configured to apply additional pressure on said lid and said core in the extended position within the cavity. The first hydraulic stage is configured to perform the following: move said core from the retracted position to the extended position and move said lid and said core in the extended position to contact a mold having a cavity with material deposited therein, with pressure being applied to said lid and said core in the extended position within the cavity.
Compression molded double wall blocks for a pallet and associated methods
A compression molding system includes a first extruder to output melted plastic, and a second extruder downstream from the first extruder to mix the melted plastic with wood chips to output a composite material. A transfer valve alternately directs the composite material between inner block molds and outer block molds. Each inner block mold has an inner block press associated therewith to press the composite material into a desired shape of an inner block having an opening on one side. Each outer block mold has an outer block press associated therewith to press the composite material into a desired shape of an outer block having an opening on one side. A press assembly presses one of the inner blocks into the opening in one of the outer blocks to form a double wall block.
Method for producing contact lenses
The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; bring a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.
Demolding device
A demolding device that removes a thin-walled part from a mold, the thin-walled part being tubular and having a partially open wall, the demolding device including: contour units that are located in a circumferential direction of the thin-walled part and each of which includes a contact structure that contacts an outer surface of the thin-walled part and moves in a thin-walled surface outward direction extending away from the outer surface of the thin-walled part; and a puller that engages with edges of the partially open wall of the thin-walled part and that applies a load to the thin-walled part, the load including a force component acting in the circumferential direction of the thin-walled part. In response to application of the load from the puller to the thin-walled part, each of the contour units moves the contact structure to keep the contact structure in contact with the thin-walled part.
