Abstract
The invention relates to a die mechanism for obliquely pushing a parallel push plate out. The die mechanism comprises parts such as a fixed mold embedding block, a mold core, a fixed mold sleeve plate, a movable mold sleeve plate, a movable mold embedding block, a reset rod, a push pipe, a push rod fixing plate, a push plate guide pillar, a movable mold base plate, a fixed mold base plate and the like, wherein the fixed mold embedding block 1 is in clearance fit in the fixed mold sleeve plate 3; the mold core 2 is in clearance fit in the fixed mold embedding block 1, is compressed by the fixed mold base plate and is integrally connected with the fixed mold base plate through a screw; the movable mold embedding block 5 is in clearance fit with the movable mold sleeve plate 4; the reset rod 6 and the push pipe 7 are connected on the push rod fixing plate and are integrally connected with a push plate 9 through screws; the push pipe and the reset rod are in inclined fit with the movable mold embedding block; the push plate guide pillar 10 is tightly fixed on the movable mold base plate and is in sliding clearance fit with a guide sleeve in the push plate; and a movable model core is tightly fixed on the movable mold base plate and is in inclined clearance fit with the movable mold embedding block 5.
Description
Technical field
The present invention relates to die cast metal moulding and injection-moulding plastic mould, is a kind of mold mechanism that utilizes parallel push pedal cant to go out.
Background technology
At present, the frame mode that is adopted on the type cavity mould ejecting mechanism has: A, manual ejecting mechanism; B, motor-driven ejecting mechanism; C, hydraulic pressure ejecting mechanism; D, air-actuated stripper structure; E, two ejecting mechanism; F, secondary ejecting mechanism; The ejecting mechanism of G, threaded goods.Owing in every circulation of injection moulding or die cast, goods are deviate from from mold cavity and core.And adopt said mechanism because goods pack tightly core when shrinking, so the position of knockout press relation is greatly, it is very big so far to cause goods to damage phenomenon when the demoulding.Precisely the complicated shape goods are very difficult when the demoulding, the adhesive force of this and goods and die cavity, especially to the package power of core, material character article shape with goods, molding technique parameter, draw taper, the core spacing, factors such as mold cavity surface roughness are relevant, therefore when determining mould structure, should take all factors into consideration above-mentioned factor, to guarantee the smooth demoulding of goods according to shape of product, material, now be combined in mould in person and design line design experiences for many years, provide following a kind of ejecting mechanism to use for mould circle.
Summary of the invention
The present invention provides the mold mechanism that a kind of parallel push pedal cant goes out goods, its action is solid and reliable, and motion has enough strength and stiffness flexibly, products appearance is good, and the position of releasing goods is chosen in the inside of goods or products appearance is influenced little position.Adopt this mechanism, mould structure simple, it is convenient to change, and resistance to sliding is little, stripping result is good, and the position freedom of setting is big, simultaneously when mould is made, cooperation is good to neutrality, can not produce overlap during moulding, is applicable to various moulding materials, adopt this mechanism in addition, its molding cycle is short, the productivity ratio height, the quality of item grace, automaticity is high, and die life is long, handling safety.
The present invention is further described below in conjunction with accompanying drawing
1---fixed die insert 2---core 3---cover half cage plate
4---dynamic model cage plate 5---moving die insert 6---release links
7---ejector sleeve 8---ejector pin retaining plate 9---push pedals
10---the push pedal guide pillar
The specific embodiment:
It shown in the figure mold mechanism that a kind of parallel push pedal cant goes out, figure a is a mould matched moulds state, after figure b is die sinking, release the state of goods, after the mould clamping is on injector or the die casting machine, mould is opened under the power of former, when after the mould dynamic model is partly with former, moving, goods stay in the die cavity of moving die insert 5 after breaking away from from mould cover half die cavity, because the package power in goods and the mould dynamic mould core is greater than the package power of mould cover half core 2, so goods stay in dynamic model partly after the die sinking, when moving after injector or the die casting machine continuation, the push pedal of mould and the push rod of former are collided, at this moment the push rod of former promotes the mould push pedal, and push pedal drives the push piece fixed head and moves, and the push piece fixed head drives and connects superincumbent push rod and ejector sleeve 7, release link 6 is done oblique action, finishes the release of goods.
Claims (1)
1. mold mechanism that parallel push pedal cant goes out, its main feature is: the two ends bevel of goods and a kind of ejecting mechanism of adopting, its main feature is: after the mould die sinking, the push pedal of mould is under the power of former push rod, promote push pedal and make linearly operating, do oblique release along the hole at inclination angle that goods become and move and finish the product disengaging and be installed in ejector sleeve, release link, push rod on the ejector pin retaining plate.This mechanism is fit to metal crimp mold and injection mold, moves solid and reliablely, and the pressure transmission is good, and mould structure is simple, and maintenance and installation is very convenient, the quality of item grace, and die manufacturing cost is low, and the economic worth of promoting the use of is arranged.
