摘要:
The purpose is to obtain a molding die, a molded product production device, and a molded product production method that enable the time for heating a cavity to be shortened and enable improvement in production efficiency. This molding die includes: a pair of dies, i.e., a first die (13) and a second die (14) respectively having abutting surfaces; a first die part (11) and a second die part (12) respectively having cavity forming portions (11A, 12A) inside which a cavity (110) is formed, and thick portions (11B, 12B) provided at both ends of the cavity forming portions (11A, 12A), the die parts being detachably fitted to die part attachment grooves (13b, 14b) provided in the abutting surfaces (13a, 14a) of the pair of dies; and induction heating coils (81) for heating a surface (110a) of the cavity (110), wherein thicknesses of the cavity forming portions (11A, 12A) are smaller than thicknesses of the thick portions (11B, 12B), and the distance between the induction heating coils (81) and the cavity (110) is smaller than the thicknesses of the thick portions.

The invention relates to a rotating unit (40) for a horizontal injection molding machine with which mold halves or molded articles that are inserted between the tool backing plates (3, 4) can be rotated about a vertical axis. The invention is further characterized in that the rotating unit (40) exclusively rests on the machine bed (2) and is entirely detached from the beams (5-8). To this end, the rotating unit (40) is provided with a base plate (14) that is supported on the machine bed and with a rotary table (13) that is supported on the base plate and can be rotated about a vertical axis. The rotating unit further comprises drive means for rotating the rotary table. The base plate (14) is substantially H-shaped, the lateral limbs (15-18) of the H resting on the machine bed (2). A gear (44) is provided that is driven by an electromotor or hydraulic motor (4) and that engages with a ring gear (43) on the rotary table (13). Said rotary table (13) is mounted on a pivot pin (19) that extends through the base plate (14) and that is additionally received by a stator (20) located below the base plate in such a manner that it can be rotated therein.

An improved drive system for rotatable members in molding machines comprises at least one frameless, brushless electric motor (38) having a stator (40) mounted on the machine (10) and a rotor (38) directly coupled to the rotatable member (16). The rotor (38) is coupled to the rotatable member (16) so that the axis of rotation (B) of the rotor (38) is concentric to the axis of rotation of the rotatable member (16).

Construction includes a stationary platen and a movable platen movable with respect to the stationary platen from a closed position in clamping engagement with the stationary platen to an open position spaced from the stationary platen. At least two tiebars are provided connecting the stationary platen to the movable platen, and a stroke cylinder within each tiebar operative to move the platens from an open to closed position and from a closed to open position. Clamping means are provided to clamp the platens together in the closed position, and including means carried by the tiebars to engage the clamping means.
