A Large Angle Inclined Secondary Core-pulling Plastic Mold Structure

Abstract

The invention discloses a large-angle oblique secondary core-pulling plastic mold structure. A second oblique drawing guide block is slidably connected to the lower part of the right side wall of the kernel cavity, a first oblique buckle is slidably connected to the left side of the outer wall of the first oblique drawing guide block, and the right side of the outer wall of the second oblique drawing guide block is slidably connected. A second oblique buckle is slidably connected, the left side of the middle part of the upper surface of the outer wall of the front mold core cavity is provided with a first hot runner glue inlet, and the right side of the middle part of the upper surface of the outer wall of the front mold core cavity is opened with a The second hot runner glue inlet, the left side of the lower surface of the rear mold core cavity is slidably connected with a first inclined top block. The invention adopts the double-needle valve hot runner, the appearance of the product is beautiful, the trace of the glue port is small, the two-part type is used to ensure smooth core pulling, and the secondary inclined-pulling connecting rod structure with the side inclined hole is adopted, which is conducive to the demoulding of the complex structure of the product. After the product is not deformed or damaged.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold structure with a large-angle oblique secondary core-pulling. Background technique [0002] Plastic mold is the abbreviation of a combined mold for compression molding, extrusion molding, injection, blow molding and low foam molding. A series of plastic parts of different shapes and sizes can be processed through the coordinated change of the mold convex, concave mold and auxiliary molding system. It mainly includes a concave mold with variable cavity composed of a die combination base plate, a die assembly and a die combination clamping plate, and a punch combination base plate, a punch component, a punch combination clamp plate, a cavity cut-off component and A punch with a variable core consisting of side-section composite plates. The molds can be divided into three types according to the different gating system types: (1) Dashuikou mold: the runner and g...

Problems solved by technology

(2) Fine nozzle mold: runners and gates are not on the parting line, usually directly on the product, so an additional group of nozzle parting lines should be designed, the design is more complicated, and the processing is more difficult. Generally, it depends on the product requirements. fine nozzle system

[0003] Existing plastic molds have obvious deformation and lack of material in the production of products, especially large-angle oblique holes will produce deformation
