Die opening/closing structure system used for injection mold

Abstract

The invention relates to a die opening / closing structure system, which comprises a panel, a plate A and a plate B, and further includes a small pull rod mechanism, a rubber plug mechanism, a push / stop block mechanism and a sliding block mechanism, wherein the small pull rod mechanism includes pull rod screws mounted in the panel, a small pull rod arranged on the pull rod screws and penetrating the plate A and the plate B, and a small pull rod spring arranged on the outer side of the small pull rod and in the plate A; a limit step matched with the head part of the small pull rod is arranged in the plate A; the rubber plug mechanism includes a rubber plug rod and a rubber plug fixed at the rod part of the rubber plug rod, wherein the head part of the rubber plug rod is matched with the step in the plate A, and the rubber plug is plugged into a hole in the plate B; the push / stop block mechanism includes a push block mounted on the panel, a stop block capable of sliding in the plate A, and block springs mounted in the stop block and the plate A. According to the system, the sliding block can move first during die opening and move last during die closing, so that the rubber shoveling phenomenon can be avoided, the product yield can be greatly improved, and the factory cost of the product is further lowered.

Description

technical field [0001] The invention relates to injection molds in the mold industry, in particular to a mold opening and closing structure system for injection molds. Background technique [0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. According to the market demand, the existing products sometimes require plastic or rubber coating on the metal parts, so that the metal parts need to be placed in the mold for production. However, when the mold is closed, the slider will move with the mold. The phenomenon of shoveling glue often occurs, so that the plastic or lagging cannot be tightly attached to the metal parts, which will cause the production of substandard products, and it is easy to cause danger when used on important machinery.
