Plastic injection molding machining mold facilitating heat dissipation and workpiece arrangement

Abstract

The invention provides a plastic injection molding machining mold facilitating heat dissipation and workpiece arrangement, relates to the field of injection molding machining, and solves the problem that an existing device cannot achieve mixing of cooling gas in a mold female base through a mechanical linkage means to improve the cooling effect, the existing device cannot achieve automatic close-range cutting after injection molding is completed, on the one hand, manual cutting wastes time, and injection molding raw material is wasted. The plastic injection molding machining mold facilitatingheat dissipation and workpiece arrangement comprises a frame body, and the mold female base is welded on the frame body; plastic liquid is jetted into the mold female base through a feeding pipe, at the moment, a locking rod moves forwards to make contact with the head end of the pipe body under the thrust effect of the liquid, an elastic piece is in a compressed state at the moment, a feeding groove is in communication with the pipe body at the moment, and therefore the normal distribution of the plastic liquid is kept; after liquid injection is finished, the locking rod is pushed by the elastic force of the elastic piece to return to the initial position, and the pipe body returns to the initial sealing state.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and more specifically relates to a mold for plastic injection molding which is convenient for heat dissipation and finishing of workpieces. Background technique [0002] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted materials into a mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. [0003] For example, the application number: CN201410436683.5, the invention provides an injection mold for processing products with oblique holes, which belongs to the field of mold technology. The injection mold includes a fixed mold middle plate, a movable mold middle plate, and a movable mold seat plate. There is a push component movable between the movable mold seat plate; a straight top block connected with the push component is embedded in...
