Method and device for the production of form parts
The invention relates to a method for the production of form parts from multi-component reactive plastic material, especially from polyurethane, wherein a plurality of moulds are moved by means of mould carriages (1) at least temporarily along a closed, preferably oval, production line (2). To allow a simple and quick import and export of mould carriages in the respectively out of the production line the invention proposes that the mould carriages (1) are provided with rolls (3) and are moved on a stationary ground (4) by the same and that a plurality of supply carriages (6) are arranged along the closed production line (2) at a conveying element (5), which supply carriages (6) are moved by means of the conveying elements (5), wherein a mould carriage (1) is approached to a not occupied supply carriage (6) and is coupled with the same to introduce the mould carriage (1) into the production line (2), wherein for the movement along the production line (2) the mould carriage (1) is guided and moved by the supply carriage (6) in a coupled state between the mould carriage (1) and the supply carriage (6) and wherein the mould carriage (1) is decoupled from the supply carriage (6) and is moved away from the production line (2) for taking the mould carriage (1) out of the production line (2), wherein here the mould carriage (1) is moved with its roils (3) on the stationary ground (4). Furthermore, the invention relates to a respective device.
MULTIPLE-COMPONENT INJECTION MOLD ASSEMBLY
An injection mold assembly for manufacturing multiple-component articles includes opposed first and second mold halves mounted for movement in reciprocal directions along an axis of reciprocation between an open position and a closed position. A stripper plate is mounted between the first and second mold halves for reciprocation between a retracted position and an extended position when the first and second mold halves are in the open position thereof. Mold cores in one of a plurality of mold core assemblies are carried by the first mold half, and each mold core is mounted for rotation between a first position and a second position about an axis of rotation for the respective mold core assembly. The stripper plate accommodates rotation of the mold cores between the first and second positions while the stripper plate is in the retracted position.
INJECTION MOLDING METHOD AND INJECTION MOLDING MACHINE
This injection molding method uses an injection molding machine for two-material molding, which comprises a first mold part that is provided with a cavity and a second mold part that is provided with a cavity and is arranged in tandem with the first mold part. This injection molding method comprises: a first molding step wherein a material is injected into the cavity of the first mold part and the material in the cavity is compressed; and a second molding step wherein a material is injected into the cavity of the second mold part. A pressure, which is generated in the second mold part by injecting the material into the cavity in the second molding step, acts on the first mold part, and a compressive force is applied to the material in the cavity in the first molding step.
One-Piece Weighing Funnel Molding Apparatus and Process
An improved molding process for molding weighing funnels. The molding process involves forming one or more mold cavities wherein each mold cavity comprises an upper cavity portion in an upper mold section and a lower cavity portion in a lower mold section. A two piece core comprising an upper core and lower core are positioned in close proximity to one another. The lower molding section is moved upward to place it in close proximity to the upper molding section to form a mold cavity while the lower core is simultaneously moved into the mold cavity into close proximity with the upper core. Plastic is injected into the mold cavity using hot runner technology to form a weighing funnel. After the weighing funnel is formed, the lower molding section is moved downward while the lower core is simultaneously retracted from the mold cavity. A robotic arm is used to remove finished product from the mold.
Resilient polymer hunting decoy
A waterfowl decoy comprising a molded body with an interior cavity, a first and second keel, and an opening through the upper side of the molded body and oriented to allow air to pass from the interior cavity through the molded body.
Active grille shutter in-tool assembly
A method of in tool formation and assembly of an active grille shutter system, followed by an automated testing process. The method includes providing a tool having a plurality of sliders that assist in the formation and assembly of the active grille shutter system. The components of the active grille shutter system are individually formed in a single tool, with each of the components being spaced apart from each other. After formation of the components a number of sliders and an end of arm tool push the components together to form the assembled active grille shutter system. The end of arm tool then takes the assembled active grille shutter system to a testing station where the operation is checked.
Dialyzer manufacturing tool
A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.
Manufacturing apparatus, manufacturing system, and manufacturing method
A manufacturing apparatus includes a defining portion, a plunger, and a valve member. The defining portion defines a supply port, a discharge port, and a resin channel. The resin channel includes a reserving portion, a first partial channel connecting the supply port and the reserving portion, a second partial channel connecting the reserving portion and the discharge port, a relay channel connecting the first partial channel, the reserving portion and the second partial channel, and a connecting channel connecting the first partial channel and the second partial channel. The plunger discharges the molten resin reserved in the reserving portion. The valve member is provided in the connecting channel and the second partial channel. The first partial channel and the relay channel are connected to the connecting channel so as to intersect with the connecting channel. The valve member includes a first valve portion and a second valve portion.
Injection mould
Injection mould for producing mouldings having a cavity plate with cavities and a core plate with cores. The cavity plate and the core plate are movable between a closed position, in which each core is respectively arranged in a cavity, and an open position, in which no core is arranged within a cavity. Each moulding space is assigned a neck-ring pair with two neck rings, and the neck-ring pair is arranged on the core plate and is movable between a holding position, in which neck rings of the neck-ring pair are in contact, and a releasing position, in which neck rings of the neck-ring pair are not in contact. To provide an injection mould with which mouldings can be produced and provided for further processing as efficiently as possible, the cores and the cavities are arranged on a curved path.
