An apparatus 10 for removing a mold section C from a molded part M. The apparatus 10 includes a base frame 11 supporting a driver 12 and a power supply, and a support member 16 for engagement with the molded part M. The driver 12 is engaged with and driven by the power supply M. The support member 16 has a clamping station for receiving and clamping the mold section C engaged with the molded part M. The clamping station 20 also has an open position for receiving the mold section C engaged with the molded part, and a closed position in which the mold section and molded part are clamped within the clamping station. The clamping station 20 further includes a heater 44, to assist with partial heating of the molded part M and mold section C prior to removal of the molded part. A removal station 22 for receiving the mold section C following removal from engagement with the molded part M is also provided, as is a force rod member 13 for engagement with the mold section, which is operated by the driver 12 for movement between the clamping and removal stations 20, 22 during removal of the mold section from the molded part.

Removal apparatus for removing a mold section from a molded part

A self-centering molding apparatus 10 for forming molded products including a first mold portion 14 and a second mold portion 15 together forming a mold cavity 16 for receiving molding material forming the molded product M. The first mold portion 14 has an alignment member 18 in fluid communication with the mold cavity 16 and for alignment and engagement with an injection press P for injecting molding material into the apparatus 10. The first mold portion 14 is adapted for self-centering, mating engagement with the second mold portion 15. The second mold portion 15 has a multi-section mold assembly 22, a support plate 24 and an operating assembly 26. The multi-section mold assembly 22 is adapted for self-centering, mating engagement with the first mold portion 14 and the operating assembly 26, and is supported on and engaged with the support plate 24 for opening and closing the multi-section mold assembly for accessing a molded product M supported within the mold cavity 16 . The support plate 24 is engaged with the operating assembly 26 and movable with respect to the second mold portion 15 to open the multi-section mold assembly 22 for accessing the molded product M within the mold cavity 16.

Self-centering molding apparatus

An injection molding machine having a machine frame, an injection assembly coupled with the frame, a press assembly also coupled with the frame, a mold-mounting assembly coupled with the press assembly, and a mold pallet assembly secured to the press assembly by the mold mounting-assembly. The mold pallet assembly includes first and second mold pallet units which define a mold cavity when they are placed in a closed condition. The mold pallet assembly further includes alignment members which ensure correct alignment between the first and second mold pallet units when in a closed condition. The first mold pallet unit includes an injection assembly for engagement with the injection assembly. The mold-mounting assembly includes first and second mold-mounting devices, securing the first and second mold pallet units, respectively, to the press assembly. The mold-mounting assembly further includes a sensor which indicates the correct alignment of the mold pallet assembly relative to the press assembly. The press assembly moves the first and second mold pallet units between a closed condition and an open condition in which they are separated from each other. Movement of the first mold pallet unit by the press assembly engages the unit with the injection assembly.

Injection molding machine including quick-change mold assembly

An apparatus for application of material to the external diameters of cylindrical items of manufacture. The apparatus includes a frame, a transport system having work stations supporting the items, an application system, and a curing system for curing the material applied to the cylindrical items. The application system includes first and second horizontally, axially spaced application rolls engagable with the items external diameter, and an adjustable reservoir system for supplying a desired thickness of material to be applied to the external diameter of the item.

Apparatus for application of a material to an external surface of items

A die assembly (10) for controlling extrudate profile dimension. The die assembly includes a die block (12) having a feed passage (16) for movably supporting a diverter member (13) within the die block, and first and second die block passages (18, 20). The diverter member (13) includes a diverter passage (32) and first and second feed openings (34, 36) interconnected by the diverter passage. One of the first or second feed openings (34, 36) has a larger diameter than the other of the first or second feed openings. The diverter member (13) is movable with respect to the die block (12) for directing extrudate flow via the diverter passage (32) through the second die block passage (20), to thereby vary the profile dimension of the extrudate exiting the die block. The die block (12) additionally includes a disposal passage (22). Movement of the diverter member (13) within the die block is provided between a first position providing communication between the first and second die block passages ( 18, 20), and a second position providing communication between the first die block passage (18) and the disposal passage (22). A die plate (14) may be readily changed by directing extrudate flow via the disposal passage (22).

Die assembly control

An apparatus for application of material to the internal surface of cylindrical items of manufacture. The apparatus includes a frame, a transport system having work stations supporting the items, an application system, and a curing system for curing the material applied to the cylindrical items. The application system includes a drive roll, movable into engagement with the item for rotating the item, a coating roll movable between a position engaging the internal surface of the item to apply the desired material, and a position engaged with a reservoir system having a rotating supply roll for supplying the coating roll with material.
