Connecting rod type mold closing type injection mold

Abstract

The invention discloses a connecting rod type mold closing type injection mold. The connecting rod type mold closing type injection mold comprises a fixed base, a sliding base, guiding rods, fixing blocks, a front mold, connecting blocks, a back mold, a pouring gate, a first air cylinder, a movable block, a first connecting rod, second connecting rods, third connecting rods, a second air cylinder,a first piston rod, an air inflator, a cushion plate, reinforcing rib plates, a cutter, a vacuum pump, a first connecting pipe, a straight pipe, an oil tank, an oil pump, an oil pipe, a three-way pipe, second connecting pipes, an oil filling port, a groove, an annular pipe, sponge rings, a circular hole, a spring, a piston rod, a limiting groove, a limiting ring, a second piston rod and a piston.According to the connecting rod type mold closing type injection mold, the structure is reasonable, a cutting structure is arranged, therefore, when the front mold and the back mold are separated, excess materials at the pouring gate can be automatically cut by means of force generated when the front mold and the back mold are separated, the subsequent machining process of injection molding partsis reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to an injection mold, in particular to a connecting-rod combined mode injection mold, which belongs to the technical field of injection mold application. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions; injection molding is a processing method used in mass production of certain complex-shaped parts; The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the molded product is obtained. [0003] The connecting rod type combined mode injection mold generally uses the connecting rod to open and close the injection mold; when the mold is opened, it may be guided by a guide rod, and wear may occur during the guide, and it is generally lubricated by manually applying lubricating oil. The manual labor intensity may increase; after the injection molded ...

Problems solved by technology

[0003] The connecting rod type joint mode injection mold generally uses the connecting rod to open and close the injection mold; when the mold is opened, it may be guided by the guide rod, and wear may occur during the guide, and it is generally lubricated by manually applying lubricating oil. The manual labor intensity may increase; after the injection molded part is formed in the cavity, there will be residual material at the gate, which may need to be cut and removed manually after being taken out, and then removed by grinding, and the process may be more
