Precise mold injection molding part forming and separating equipment

Abstract

The invention relates to precise mold injection molding part forming and separating equipment comprising an injection molding machine. A workbench is arranged on the left side of the injection moldingmachine; an air cylinder fixing base is installed in the middle of the upper surface of the workbench; a first finger air cylinder is fixed to the middle of the upper end of the air cylinder fixing base; a clamping jaw used for containing an injection molding part is fixed to the working end of the first finger air cylinder; the working end of the first finger air cylinder is arranged upward; a rotary pick-up device is arranged on the rear side of the air cylinder fixing base; the rotary pick-up device takes the injection molding part out of the injection molding machine and places the injection molding part on the clamping jaw, and a first material collecting assembly and a second material collecting assembly which are used for collecting spare parts of the injection molding part are arranged on the left side and the right side of the air cylinder fixing base correspondingly; the front side of the air cylinder fixing base is provided with a third material collecting assembly used forcollecting the spare parts of the injection molding part; and the rear side of the rotary pick-up device is provided with an injection molding part separating mechanism. The precise mold injection molding part forming and separating equipment is high in automation degree, the product percent of pass is increased, the cost is saved, the working efficiency is improved, and a good market applicationvalue is achieved.

Description

technical field [0001] The invention relates to the technical field of connector pins and testing, in particular to a precision mold injection molding separation device. Background technique [0002] In the production of injection molded parts, production modes such as one mold with two cavities and one mold with four cavities are often used. Taking one mold with four cavities as an example, four pieces are produced at the same time after injection molding with a mold with four cavities. Injection molded parts, during the injection process, the liquid resin flows in from the mold inlet, then flows through the flow channel set in the mold, and then divides the liquid into the four product cavities at the end. After the injected resin cools down, four connected injection molded parts are obtained. The common connection between the four injection molded parts is called the runner, and the connection position between the injection molded part and the runner is called the gate. I...

[0002] In the production of injection molded parts, production modes such as one mold with two cavities and one mold with four cavities are often used. Taking one mold with four cavities as an example, four pieces are produced at the same time after injection molding with a mold with four cavities. Injection molded parts, during the injection process, the liquid resin flows in from the mold inlet, then flows through the flow channel set in the mold, and then divides the liquid into the four product cavities at the end. After the injected resin cools down, four connected injection molded parts are obtained. The common connection between the four injection molded parts is called the runner, and the connection position between the injection molded part and the runner is called the gate. In order to obtain a single product, after the injection molding machine opens the mold, the injection molded part must be separated from the mold and the single product and the mold must be separated. The runner is disconnected from the gate, and the separation and disconnection work is often done manually, which consumes a lot of manpower, resulting in an increase in production costs and a decrease in production efficiency, or the injection molded parts are cut at the gate by an automatic punching structure. Splitting by shearing, because this separation method directly exerts a large external force on the injection molded parts, it is easy to cause deformation of the injection molded parts, increase the scrap rate, and also increase the production cost, and a single shearing mechanism cannot simultaneously The gate is sheared, the separation efficiency is low, and some equipment does not set up a collection box for collecting waste after separating the injection molded parts, which pollutes the working environment
