An apparatus for molding plastic elements includes a device for injection molding elements made of plastics and a device for unloading the molded plastic elements from the molding device. The molding device is associated with an extraction plate adapted to move, on command, at least one part of the molding device in order to allow the unloading of the plastic elements. The extraction plate is connected functionally, by way of posts to an actuation element and an abutment body and further actuation elements are provided which act between the abutment body and the actuation element and are adapted to move, substantially parallel to the direction of extension of the posts, the actuation element with respect to the abutment body. The abutment body is arranged between the extraction plate and the actuation element.

An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.

An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller performs active control in conjunction with the positioning, control by the servomotor. At the beginning of the active control, the positioning control is primarily performed by the servomotor, and then the active control is positively performed by the active controller using an electric actuator. Compared with when only the active control is performed for vibration suppression, a lighter and smaller electric actuator can be employed.

A method of manufacturing a component (124) having a main body (116) and at least one ring sleeve (118) through a molding assembly (100), the method comprising: providing a mold (102) having an inlet (115) and defining a hollow portion (H); placing at least one core to form a free-space (104, 106) within the component (124) inside the mold (102) to bifurcate the hollow portion (H) into a first cavity and a second cavity; pouring a molding material (117) inside the mold (102) through the inlet (115); allowing the molding material (117) to set inside the mold (102) around the core within the first cavity and the second cavity to form a main body (116) and at least one ring sleeve (118) of the component (124); connecting the first cavity and the second cavity and forming at least one first bond and one second bond (130, 132, 134, 136) between the main body (116) and the at least one ring sleeve (118); and removing the at least one core from at least part of the hollow portion (H) within the mold (102); characterized in that: providing the core with at least one recess allowing the molding material (117) to flow therethrough such that on withdrawing the core out of the mold (102), at least one first bond (130, 132) breaks and on withdrawing the core outside the mold (102), at least one second bond (134, 136) breaks.

A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

An apparatus for taking out a molded product is provided, the apparatus being capable of suppressing displacement vibration of an attachment mounted at a leading end of each of one or more approach frames by active control using one or more electromagnetic actuators. The apparatus includes an active vibration suppressing system. One or more electromagnetic actuators are mounted to the attachment of each approach frame or each approach frame.

There is provided a method capable of manufacturing a mold at low cost, and a method of manufacturing a biocompatible pattern sheet by using the mold. The method of manufacturing a mold having a recessed pattern includes the steps of: forming a silicone resin film by applying a silicone resin solution to a surface of a model having a protrusion pattern; defoaming the silicone resin film by reducing the silicone resin film in pressure; forming the mold by heating and curing the silicone resin film while a base plate is in contact with a face of the silicone resin film, the face being opposite to the model; and releasing the mold from the model after releasing the base plate. The method of manufacturing a pattern sheet uses the mold.

A mold for forming an element molded from a particle foam, including for example expanded polypropylene foam, includes at least one visible exterior surface defined by the particle foam. The visible exterior surface is textured having a roughness depth of less than or equal to 1.00 mm and a plurality of vent interfaces each having a maximum width of less than or equal to 0.4 mm. Methods of molding the element, together with a mold and a method of making the mold, are also provided.

Embodiments of the invention include a mold for forming a tire tread. The mold includes a tongue forming portion at an end of a tread forming portion. The tongue forming portion has a substantially constant thickness, except for a portion at an end of the tongue forming portion having a thickness greater than a thickness of a remainder of the tongue forming portion.
