Rotary Injection Molding Machine

Abstract

The invention provides a rotary type injection molding machine. In a rotary type injection molding machine of a flow which is used on a motion of a mold member or on a clamp of the mold member, the rotary type injection molding machine can guarantee a motion that the mold has or a clamping response of the mold member, or the rotary injection molding machine realizes inhibition of pressure loss offlow and the metal mold is easy to change. The mold can be opened and closed on a horizontal direction of the movable plate (18) relative to the fixed plate. The rotary working stable (31) for installing the molde member (15) is rotatably arranged on one of the fixed plate (17) or the movable plate (18). In the rotary type injection molding machine, on which the flow is used on the motion of the molding member or the clamp (35) of the mold member, flow valve (52) is positioned on the outer circumference along an emission direction relative to the rotary working table.

Description

Technical field [0001] The present invention relates to a movable plate that opens and closes a mold in the horizontal direction with respect to a fixed plate, and a rotary table on which mold parts are mounted is rotatably provided on either the fixed plate or the movable plate. The movement of the mold parts or the mold Rotary injection molding machine using fluid for parts clamping. Background technique [0002] As a movable plate that opens and closes the mold in the horizontal direction with respect to the fixed plate, the rotary table on which the mold parts are mounted is rotatably installed on the fixed plate or the movable plate. The movement of the mold parts or the mold parts A rotary injection molding machine using a fluid for the clamp is known as described in Patent Document 1. In Patent Document 1, a core of a mold member that is operated by hydraulic pressure is provided on a movable metal mold. In addition, a long hydraulic pipe having flexibility is provided a...

Problems solved by technology

[0007] However, in the structure described in Patent Document 2, the valve device is provided on the center side of the mold mounting position on the surface of the rotary table, so the valve device becomes an obstacle when the mold is mounted.

In particular, as in the rotary injection molding machine that opens and closes the mold in the horizontal direction, when the mold is replaced, the mold is carried in from the direction perpendicular to the mold opening and closing direction of the rotary table, and the mold is rotated The vicinity of the front of the center of the table moves toward the installation position, so if the valve unit is installed on the center side, it will become an obstacle when loading the mold
