Embodiment Construction

[0020] refer to Figure 1 ~ Figure 3 A mold rotary injection molding machine 11 according to an embodiment of the present invention will be described. A mold rotary injection molding machine 11 , which is a type of injection molding machine, basically includes a mold clamping device 12 , and a first injection device 13 and a second injection device 14 provided on both sides thereof. The clamping device 12 fixes four connecting rods 16 in the upright direction on the fixed disk 15 arranged below, and an upper disk 17 is fixed above the connecting rods 16 . In addition, the connecting rods 16 are inserted around the four corners of the movable platen 18 , and the movable platen 18 can move in the vertical direction between the fixed platen 15 and the upper plate 17 . In addition, a mold clamping cylinder 19 is provided on the upper plate 17 , and the piston 20 of the mold clamping cylinder 19 is fixed on the back surface of the movable plate 18 . In addition, an unillustrated ...

Abstract

The invention provides a mold rotation type injection molding machine (11) and a rotary table rotation method. A rotary table (21) of molds (29a, 29b) is provided in a manner that a belt (26) rotates with respect to a fixing disc (15) or a movable disc (19). The belt does not need to be fixed to the rotary table, and design free degree or cost reduction can be ensured. The mold rotation type injection molding machine (11) comprises the rotary table (21) having a belt cooperation part (28) at the periphery side, a motor (23) disposed near the side of the rotary table (21), a joint part (32) connecting end parts, and a belt (26) transmitting the drive of the motor (23) to the rotary table (21). The joint part (32) of the belt (26) always abuts against the belt cooperation part (28) to rotate the rotary table (21).

Description

technical field [0001] The present invention relates to a mold rotary injection molding machine and a method for rotating a turntable of the mold rotary injection molding machine. turntable. Background technique [0002] As a mold rotary injection molding machine provided with a turntable on which a mold is mounted so as to be rotatable relative to a fixed platen or a movable platen, there are a system using an electric motor as a driving source and a system using a hydraulic cylinder as a driving source. In recent years, The method of using electric motors as the driving source has become the mainstream. Among the methods using the motor as the driving source, the following methods are known: a method of transmitting the driving force of the motor to the central axis to rotate the turntable; method; and a method in which a timing belt is wound between the outer peripheral side of the turntable and the drive gear of the motor, and the driving force of the motor is transmit...
