Abstract
The utility model discloses an ejecting dark chamber mould of secondary includes cover half, movable mould, fixed plate in proper order and fixes the mould foot in the fixed plate both sides, connect through the guide pillar between cover half, movable mould and the fixed plate, all be equipped with the kicking block of L shape on the mould foot of both sides, the below of going up of kicking block is equipped with secondary roof and a roof respectively, a right -angle side of kicking block articulates on the mould foot, its outer right angle orientation a roof, another right -angle side orientation the secondary roof, be equipped with a plurality of ejector pins on the roof, the tip of ejector pin passes the butt is in behind secondary roof and the fixed plate the movable mould below, be equipped with on the secondary roof with the communicating compression thimble of mold core. The utility model discloses using L shape kicking block and as the lever, realizing that the secondary is ejecting, simple structure is reliable, and the drawing of patterns is efficient, low in manufacturing cost, and the practicality is strong.
Description
Technical field
This utility model relates to mould applications, particularly relates to a kind of deep cavity mould of Double-ejection.
Background technology
Die casting machine is exactly under pressure cooling down molding in molten metal bath injection to mould, obtains solid after die sinking
A series of industry foundry machinery of metal casting, are used primarily for die casting font.Along with scientific and technical and industrial progress, especially
It is as the industrial expansions such as automobile, motorcycle and household electrical appliance, and aspects sets out, and die-casting technique has obtained the rapidest
Development.General product is all to be ejected action carried out depanning by the most complete, but packs tightly the spy of great efforts for some
Different product, after use once ejects, can not be completely disengaged from mould, for deep cavity mould, and mould fuse
Diameter excessive more than enclasping force during 30mm, in ejection process, thimble is easily deformed, and product is easily damaged, yield rate and produce effect
Rate is low, and therefore people utilize Double-ejection mode ejecting product at twice.Existing secondary ejection mold structure is complicated, it is numerous to assemble
Trivial, manufacturing cost is high, fault rate is high thus causes poor practicability.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of deep cavity mould of Double-ejection.
For achieving the above object, this utility model is by the following technical solutions:
A kind of deep cavity mould of Double-ejection, includes cover half, dynamic model, fixed plate successively and is fixed on the mould of fixed plate both sides
Foot, is connected by guide pillar between described cover half, dynamic model and fixed plate, and the mould foot of described both sides is equipped with the jacking block of L-shaped, described
The upper and lower of jacking block is respectively equipped with secondary top board and a top board, and a right-angle side of described jacking block is hinged on described mould foot,
Its outer right angle is towards a described top board, and another right-angle side is towards described secondary top board, and a described top board is provided with some
Push rod, the end of described push rod is connected to below described dynamic model after described secondary top board and fixed plate, described secondary top board
It is provided with the compression thimble communicated with core rod.
After using technique scheme, this utility model, compared with background technology, has the advantage that cover half divides with dynamic model
After opening, first promote a top board when the liftout attachment of die casting machine is released, push rod on a top board promote dynamic model make dynamic model with
Fixed plate separates (product departs from, and product enclasping force reduces) with middle fuse, and after separating one section, a top board touches L-shaped top
Block, L-shaped jacking block rotates and is released by secondary top board, and the compression thimble just product on secondary top board disengages with dynamic model, this practicality
Novel utilizing L-type jacking block as lever, simple and reliable for structure, demoulding efficiency is high, and low cost of manufacture is practical.

Fig. 2 is this utility model front view；
Fig. 3 is this utility model side view.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of deep cavity mould of Double-ejection, include successively cover half 1, dynamic model 2, fixed plate 3 and
Being fixed on the mould foot 4 of fixed plate 3 both sides, connected by guide pillar 5 between described cover half 1, dynamic model 2 and fixed plate 3, cover half 1 is with dynamic
Mould 2 can be movable along guide pillar 5.Being equipped with L-shaped jacking block 6 on the mould foot 4 of both sides, the quantity of jacking block 6 is 4, is distributed respectively
Both sides at mould foot 4.The upper and lower of jacking block 6 is respectively equipped with secondary top board 7 and a top board 8.One right-angle side of jacking block 6 is hinged
To realize swinging up and down on mould foot 4, its outer right angle is towards a top board 8, and another right-angle side is towards secondary top board 7, one
Secondary top board 8 is provided with some push rods 81, and the end of push rod 81 is connected to dynamic model 2 times after secondary top board 7 and fixed plate 3
Side, is additionally provided with the compression thimble 71 communicated with core rod on secondary top board 7.During the demoulding, after cover half 1 separates with dynamic model 2, work as die casting
The liftout attachment of machine first promotes a top board 8 when releasing, and push rod 81 promotes dynamic model 2 to make dynamic model 2 separate with fixed plate 3 and (now produces
Product depart from middle fuse, and product enclasping force reduces), after the two separates a segment distance, a top board 8 touches L-shaped jacking block 6
Right-angle side makes L-shaped jacking block 6 rotate, and secondary top board 7 is released by another right-angle side of L-type jacking block 6, and now dynamic model 2 is not
Dynamic, product is separated by the compression thimble 71 on secondary top board 7 with dynamic model 2, takes out product and i.e. completes stripping action.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is as the criterion with scope of the claims.
