Fixing base for injection molding machine

Abstract

The invention discloses a fixing base for an injection molding machine, and relates to the technical field of injection molding machines. The fixing base comprises a fixing seat, a rotating portion and a mounting seat, wherein a first annular groove and a second annular groove are formed in the two opposite side surfaces of the rotating portion correspondingly, an end of the fixing seat is rotationally arranged in the second annular groove, and a ring body matched with the first annular groove is arranged on the bottom surface of the mounting seat; and a mounting hole communicating with the second annular groove is formed in the bottom surface of the first annular groove, a column body is arranged in the mounting hole, the two ends of the interior of the column body are in contact with an end of the fixing seat and an end surface of the ring body correspondingly, and the end of the fixing seat and the end surface of the ring body are corrugated surfaces. According to the fixing base, gas enters a gas guide groove between the ring body and the first annular groove through an exhaust channel, so that heat dissipation of the connecting surface between the ring body and the first annular groove is realized.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines, in particular to a fixed base for injection molding machines. Background technique [0002] The base of the injection molding rotary machine is composed of a base and a rotating disk installed on the base. The rotating disk can rotate on the base. Since the base and the rotating disk directly form surface contact, the contact area between the base and the rotating disk is large. During the rotating process of the rotating disc, the frictional force formed is very large. When the rotating disc rotates, there will be friction and heat generation between the base and the base, resulting in the locking phenomenon between the base and the rotating disc, so that the rotating disc cannot rotate, which seriously affects the performance of the injection molding machine. work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a fixed base...
