Abstract

The invention provides an injection molding mold and an injection molding method using the same. The invention provides an injection molding mold. The injection molding mold comprises a mold frame assembly, a supporting assembly, a first jacking assembly and a second jacking assembly. The mold frame assembly is supported at the top end of the supporting assembly and is used for molding an injection molding part; the second jacking assembly is located between the first jacking assembly and the mold frame assembly, the first jacking assembly comprises a cutter, and the second jacking assembly comprises at least one ejector pin; when the first jacking assembly moves towards the mold frame assembly to a first position, the cutter penetrates through a cutting part of the injection molding part to separate a sprue part of the injection molding part from an injection molding body, and the ejector pin is located at an initial position; and when the first jacking assembly jacks up the second jacking assembly and moves towards the mold frame assembly to a second position, the ejector rod jacks up the injection molding body. The injection molding mold is high in operation efficiency, and the product yield can be increased.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection molding mold and an injection molding method using the same. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding machines can be divided into vertical type, horizontal type and vertical-horizontal compound type according to the arrangement of injection device and clamping device. [0003] The injection molding machine is usually composed of an injection molding system, a mold clamping system, a transmission system electrical control system, a heating and cooling system, etc. The injection mold is controlled by the injection molding machine to close the mold, and under a certain pressure and speed, the molten metal is melted t...
