Abstract

The utility model discloses a die for secondary ejection. The die consists of a sprue bush, a guide sleeve, a fixed template, a guide column, a movable template, a movable die base plate, a resetting rod, a cushion block, a push rod fixing plate, a push plate, a movable die seat plate, a second cushion block, an ejection plate, a cutter, a pressing plate, a supporting column, a square ejection rod, cores, a material pulling rod, a hydraulic cylinder and the like. A basic working process of the die is that after a product is formed, the hydraulic cylinder drives the ejection plate and the pressing plate to drive the cutter to move forwards and close a sprue, and a product and runner channel is cut off, so that primary ejection is finished; when the product is returned, the sprue is cut off, and the push rod fixing plate drives the square ejection rod to push the product out. The die firmly and reliably works and is high in pressure transmission capacity; due to the optimized module design, the die structure is simplified; the automation degree is high; the production cost is saved; the working efficiency is improved; the product is attractive in appearance; the die is suitable for various products for secondary ejection, which are formed by injection molding by metal press-casting dies and plastic injection dies.

Description

A kind of mould of Double-ejection
Technical field:
The present invention relates to metal die-casting mold and plastic injection mould, is a kind of mould of Double-ejection.
Background technology:
The ejecting mechanism that adopts on metal die-casting mold and plastic injection mould at present has: (1) is ejecting mechanism manually, after it is die sinking, eject goods by manually-operated ejecting mechanism, though its mould structure is simple, but labor strength is large, production efficiency is extremely low, and safety of workers can not get ensureing simultaneously.(2) motor-driven ejecting mechanism, it is the ejecting mechanism that relies on the die sinking action drives mould of injector, realize the goods automatic demoulding, although its mold actions is solid and reliable, the pressure transmission is good, product quality is graceful, but mould structure is very complicated, brings very big inconvenience to production line manufacturing, installation, debugging and mold repair.In order to overcome the deficiency of above-mentioned mold mechanism, I am according to for many years Design and manufacture experience, and the spy provides the mould of following a kind of Double-ejection to solve the problems referred to above.
Summary of the invention:
The present invention provides a kind of mould of Double-ejection.It is achieved in that after clamping mould is on injector or the die casting machine mold cavity is filled full of pressurize, cooling, the Driven by Hydraulic Cylinder top board, and pressing plate drives cutting knife and moves ahead, and seals gate location, namely cuts off goods and runner path, finishes ejecting the first time; Continue die sinking, hydraulic cylinder drives the cutting knife rollback and cuts off mouth, and ejector pin retaining plate drives square push rod and travels forward along guide pillar, ejects goods, finishes to eject for the second time.A kind of mould of Double-ejection, it is characterized in that: sprue bush (1) cooperates with solid plate (3) glade plane space, guide pin bushing (2) is fastened in the stepped hole of solid plate (3) and is and is slidingly matched with guide pillar (4) in the stepped hole that is installed in moving platen (5), release link (7) is installed in push pedal (10) and upward and with dynamic model backing plate (6) and moving platen (5) glade plane space cooperates, cutting knife (14) is installed in pressing plate (15) upward and uses screw fastening, and then with push pedal (10), ejector pin retaining plate (9), dynamic model backing plate (6), moving platen (5) matched in clearance, square push rod (17) is installed in the push pedal (10), then with dynamic model backing plate (6), moving platen (5) is communicated with, the first core (18) and the second core (19), the 3rd core (20), the 4th core (21) is installed in moving platen (5) and upward and with dynamic model backing plate (6) compresses, hydraulic cylinder (26) is installed on mould dynamic model one side's the lateral surface of cushion block (8), guide pillar (27) is installed in the stepped hole of dynamic model backing plate (6), again with ejector pin retaining plate (9) and push pedal (10) matched in clearance.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing
