Metal mould rotary injection molding machine and rotation method of rotating table thereof

Abstract

Provided are a metal mould rotary injection molding machine which uses a relative simple structure to confine a forwarding limit of a rotating table, wherein an outer side of the rotary table does not swing but rotates stably, and a rotation method of a rotating table thereof. A fixing disk (17) or a movable disk (18) is rotatably and separately arranged in a metal mould rotary injection molding machine (11) provided with a rotating table (22) of a rotating metal mould (29); a separation restriction mechanism (38) for restricting the separation of the a rotating table (22) is arranged on an part except the part of a rotating shaft (27) of the rotating table (22) against which the disks are abutted. The separation restriction mechanism (38) is provided with a rolling mechanism (47) for abutting against the rotating table (22).

Description

technical field [0001] The present invention relates to a rotary mold injection molding machine in which a rotary table on which a rotary mold is mounted is rotatably and separably provided on one of a fixed disk and a movable disk, and the rotation of the rotary table of the rotary mold injection molding machine method. Background technique [0002] With regard to a rotary mold injection molding machine in which a rotary table on which a rotary mold is mounted is rotatably and detachably provided to one of the fixed disk and the movable disk, there is known an upper movable disk of a vertical mold clamping device. Patent Document 1 with a rotary table, Patent Document 2 with a rotary table on the lower fixed plate of the vertical mold clamping device, and Patent Document 3 with a rotary table on the movable plate of the horizontal mold clamping device , Patent Document 4, and Patent Document 5 in which a rotary table is provided on a fixed plate of a horizontal mold clampi...

AI Technical Summary

Problems solved by technology

[0013] As described above, in Patent Document 1 to Patent Document 5, there is a possibility that the rotary table cannot be rotated stably.

That is, although Patent Document 1 to Patent Document 5 have a partition mechanism for the rotary table, they do not have a mechanism to limit the advance limit of the rotary table, or even if they have a structure that uses a spring or a structure formed on a part of the rotary shaft, so The table may shake during the rotation of the rotary table

In addition, if the table is shaken during the rotation of the rotary table, as a result, the sleeve and the bearing between the movable plate and the rotating shaft of the rotary table may be partially worn or damaged during long-term use. more sexual

In addition, in Patent Document 4, when the rotary table is rotated, the pressing member and the member for partition contact from the upper surface side and the lower surface side of the table, but since they are in surface contact, the frictional resistance is low. Big
