Abstract

The utility model provides a mould structure with a pouring head at a slide. The mould structure has the effects that the pouring head is convenient to take out during demoulding, the attractive appearance of a product is ensured, the continuous product manufacturing capability is good, and the production efficiency is high. The mould structure comprises a front mould, a rear mould, a front mould plate, a rear mould plate and a runner, wherein the runner penetrates through the front mould plate and the front mould and then is communicated with the pouring head; and particularly, the pouring head is a submarine pouring head comprising a horizontal section and an inclined feeding section. The mould structure is characterized in that the inclined feeding section of the submarine pouring head penetrates a slide insert; a mounting groove is formed in the middle of the slide insert; a movable ejector pad is embedded in the mounting groove and supports the horizontal section of the submarine pouring head; the top of a round ejector pin is embedded in a horizontal linear groove at the bottom of the movable ejector pad; the round ejector pin penetrates the rear mould plate; the bottom of the round ejector pin is in fastening connection with the combination body of an ejector retainer plate and an ejector base plate; a cavity is formed between the rear mould plate and the ejector retainer plate; and the slide insert is in fastening connection with an insert fixing block.

Description

A kind of cast gate is positioned at the mould structure of row position

Technical field

The utility model relates to the mould structure technical field to the demanding product of outward appearance, is specially the mould structure that a kind of cast gate is positioned at the row position.

Background technology

Existing to the demanding product of outward appearance; Battery of mobile phone shell for example, its pouring gate structure need design a non-outward appearance side of loosing core in the position of being expert at, and such requirement has brought very big difficulty for the smooth taking-up of cast gate; It makes the ability that manufactures a product continuously of mould, and output efficiency is low.

Summary of the invention

The utility model provides a kind of cast gate to be positioned at the mould structure of row position, and cast gate was convenient to remove when it made the demoulding, and had guaranteed the appearance looks elegant of product, and the ability that manufactures a product continuously of mould is good, and output efficiency is high.

A kind of cast gate is positioned at the mould structure of row position; It comprises front mould, back mould, front template, rear pattern plate, runner, and said runner is communicated with cast gate after running through said front template, front mould, and said cast gate is specially sub marine gate; Said sub marine gate comprises horizontal segment, oblique pan feeding section; It is characterized in that: the oblique pan feeding section of said sub marine gate runs through row position mold insert, and the middle part of said row position mold insert has mounting groove, and movable pushing block is flush-mounted in the said mounting groove; The horizontal segment of said sub marine gate is supported on said movable pushing block; The top of dome pin is embedded in the straight horizontal wire casing of said movable pushing block bottom, and said dome pin runs through said rear pattern plate, is fastenedly connected the combination of face needle plate, end needle plate bottom it, between said rear pattern plate, the face needle plate cavity is arranged; Said row position mold insert is fastenedly connected said mold insert fixed block; Said mold insert fixed block has oblique guide-track groove, and the lower end of running through the oblique guide rail of said front template is positioned at said oblique guide-track groove, and said mold insert fixed block is supported on said rear pattern plate.

After adopting the structure of the utility model, during injection moulding, stream is expected along runner, sub marine gate to front mould, the formed die cavity material feeding of back mould; Until formed product, take off front mould afterwards, obliquely cause driving mold insert fixed block level to moving; The top of dome pin breaks away from the mold insert fixed block until oblique guide rail, at this moment in the straight horizontal wire casing occurred level position of movable pushing block bottom; Sub marine gate breaks away from product, moves on the combination of face needle plate, end needle plate afterwards, makes to move on the dome pin; Move thereby force on the movable pushing block, because the horizontal segment of sub marine gate is supported on movable pushing block, the material of the horizontal segment of sub marine gate is ejected; Terminal level section material web oblique pan feeding section material and is ejected together, and cast gate was convenient to remove when it made the demoulding, and has guaranteed the appearance looks elegant of product; The ability that manufactures a product continuously of mould is good, and output efficiency is high.
