Abstract

The invention relates to an injection mold, in particular to an automatic hot-cutting side gate injection mold. The injection mold comprises a front mold fixing plate, a front mold core, a front mold plate, a rear mold core, a rear mold plate which is used for fixing the rear mold core and a rear mold fixing plate which is provided with a pushing hole, wherein the front mold plate and the rear mold core are used for fixing the front mold core; a part cavity, a pouring channel and a gate are formed between the front mold core and the rear mold core; and a gate shearing device and a product push-out device are arranged below the rear mold plate. The injection mold is characterized in that: a material handle push-out device is arranged on the rear mold plate; the product push-out device is arranged between the rear mold plate and the rear mold fixing plate; the gate shearing device is arranged between the product push-out device and the rear mold fixing plate; and the material handle push-out device is arranged on the rear mold plate. The automatic hot-cutting side gate injection mold is suitable for producing injection molding products which have complicated shapes and strict appearance requirements; and residues do not exist at an incision, subsequent secondary machining is not required, the mold is not required to be maintained and welded, and a gate cutter has long service life.

Description

technical field

[0001] The invention relates to an injection mold, in particular to an automatic mold which is suitable for injection molding production with complex shapes and strict appearance requirements, and has no residue in the cut, no need for subsequent secondary processing, no need for maintenance and welding of the mold, and long service life of the gate cutter. Hot cut side gate injection mold, gate cutter used and injection molding process. Background technique

[0002] At present, most injection molding parts are produced by side-feeding two-plate molds. The advantages of side-feeding are uniform glue feeding, no punch marks, and low internal stress of the product, but the disadvantages are cumbersome post-processing and many people. In order to solve the problem of cumbersome secondary processing and reduce labor costs while using side glue ports, in-mold automatic cold cutting is often used. This method can only be used for products with simple structures and...
