Pure pneumatic control automatic sprue cutting mold

Abstract

The invention discloses a pure pneumatic control automatic sprue cutting mold which comprises a fixed mold part (1) and a movable mold part (2) which are matched with each other. A fixed mold core and a movable mold core are arranged in the fixed mold part (1) and the movable mold part (2) separately, and the fixed mold core and the movable mold core define a cavity in a mold closing state; the automatic sprue cutting mold is characterized in that a sprue cutting cylinder (3) is arranged in the movable mold part (2); the working end of the sprue cutting cylinder (3) is connected with a sliding block seat (4), and the sliding block seat (4) is connected with two strip-shaped sliding blocks (5) which are symmetrically distributed; the strip-shaped sliding blocks (5) are slideably connected in a sliding way formed in the movable mold core, and a plurality of cutters (6) are arranged on the strip-shaped sliding blocks (5); and the number and position of the cutters (6) are matched with those of workpieces in the cavity one by one.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a pure air-controlled automatic gate-cutting mold. Background technique [0002] Injection molding is a method of producing industrial products, which mainly needs to be realized by using a molding machine and supporting molds. This process is the main molding equipment for injecting thermoplastics or thermosetting materials into molds to form plastic products of various shapes. The workpiece produced by the injection mold is still connected between the workpiece and the material handle after demoulding, so the gate cutting operation is required. There are generally two traditional ways to remove the gate, one is the most common manual operation method, which requires a lot of human resources and labor, the cost is relatively high and the quality of the gate is not stable; the other is The second is to make special automatic gate cutting equipment according to the shape of the wo...

Problems solved by technology

There are generally two traditional ways to remove the gate, one is the most common manual operation method, which requires a lot of human resources and labor, the cost is relatively high and the quality of the gate is not stable; the other is The second is to make a special automatic gate cutting device according to the shape of the workpiece and the material handle. This method requires the design of a relatively complex mechanical structure and a variety of electronic components, which is very expensive.
