The workpiece on side, it cannot be processed by the method for direct core pulling, the mould type for being machined with in-flanges on usual market
Core is disposed as hollow and collapsible, and the Product Precision that so can be processed in the engineering of life-time service is not high to be showed
As, thus how to be molded by in-flanges workpiece and withdrawing pattern process not defective work piece be grinding tool industry a difficult point.
The content of the invention
The purpose of this utility model is to provide a kind of simple structure and stable, many parts of the demoulding twice and not defective work piece
Pulled core structure twice.
What the purpose of this utility model was realized in：
A kind of many parts pulled core structure twice, including solid plate and moving platen, form between the solid plate and moving platen
Left and right two chambers, are movably set with core package in chamber, core package is driven by power set, and carries out left and right directions
Activity, the core package includes the sprue puller being connected with power set, and the end of sprue puller is provided with mutually fits with the chamber
The top matched somebody with somebody, comes directly towards bottom and is equipped with several latches with the week side of boss of sprue puller, and the perigene of latch is provided with several pulling blocks, draws
It is continuously coupled between block and the top.
The pulling block is provided with flange, and flange is adapted with the chamber.
The latch is provided with inclined ramp, the pulling block be provided be adapted with the inclined ramp it is tilted tiltedly
Face.
The pulling block lower end is provided with back-moving spring, and back-moving spring provides the trend that pulling block is inwardly moved.
The latch is I shape.
The power set are hydraulic cylinder.
This utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
1st, left and right two chambers, an injection molding two are formed between the solid plate of the present utility model and moving platen
Part so that working (machining) efficiency is higher, core package is driven by power set, and carries out left and right directions activity, the core group
Part includes the sprue puller being connected with power set, and the end of sprue puller is provided with the top being adapted with the chamber, comes directly towards bottom
Portion is equipped with several latches with the week side of boss of sprue puller, and the perigene of latch is provided with several pulling blocks, pulling block and the top
Between it is continuously coupled, it is ensured that the appearance flatness of the product being molded, pulling block is provided with flange, and the flange is used to be molded varus
Side, because the core package in in-flanges is not easy to pull out, therefore is provided with latch, by extracting between pulling block and sprue puller
Latch so that there is certain gap between pulling block and sprue puller, pulling block inwardly shrinks carries out the secondary demoulding, realizes not damaged
In-flanges product cast and the demoulding, the simple structure and stable, can disposably be molded multiple products, efficiency high.
2nd, the latch of the present utility model is I shape, and I shape latch causes structure more stable, and is caused
There is certain space between latch and latch, be easy to be pulled out during die sinking.
3rd, the latch of the present utility model is provided with inclined ramp, and the pulling block is provided with mutually fits with the inclined ramp
The tilted inclined-plane matched somebody with somebody so that pull out latch more convenient.
4th, the pulling block lower end of the present utility model is provided with back-moving spring, and back-moving spring provides becoming for the inside motion of pulling block
Gesture, after latch is pulled out, pulling block can be shunk due to the traction of back-moving spring so that overall structure is more reasonable, and two
Secondary die sinking is in hgher efficiency.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described with specific embodiment, as shown in Fig. 1-4：
A kind of many parts pulled core structure twice, including solid plate 1 and dynamic model 2, shape between the solid plate 1 and moving platen 2
Into left and right two chambers 11, two parts of an injection molding so that working (machining) efficiency is higher, and in chamber 11 core is movably set with
Component, core package is driven by power set, and carries out left and right directions activity, and the core package includes and power set phase
Sprue puller 9 even, the end of sprue puller 9 is provided with the top 8 being adapted with the chamber 11, comes directly towards 8 bottoms with sprue puller 9
The week side of boss is equipped with several latches 5, preferably three latches 5, and the perigene of latch 5 is provided with several pulling blocks 6, preferably three
Draw fast 6, it is continuously coupled between pulling block 6 and the top 8, it is ensured that the appearance flatness of the product being molded.
The pulling block 6 is provided with flange, and flange is adapted with the chamber 11, and pulling block is carried out more according to the demand of product
Change, the flange is used to be molded in-flanges, completes the cast of the in-flanges of different product so that use range is wider.
The latch 5 is provided with inclined ramp 7, and the pulling block 6 is provided with tilted with what the inclined ramp 7 was adapted
Inclined-plane, inclined ramp 7 causes pull-out latch more convenient.
The lower end of the pulling block 6 is provided with back-moving spring 10, and back-moving spring 10 provides the trend that pulling block is inwardly moved, works as pull-out
After latch 5, pulling block 6 can be shunk due to the traction of back-moving spring 10 so that overall structure is more reasonable, twice-die-opening
It is in hgher efficiency.
The latch 5 is I shape, and I shape latch causes structure more stable, and cause latch 5 and latch 5 it
Between have certain space, be easy to die sinking when pull out.
The power set are hydraulic cylinder 3, and hydraulic cylinder 3 causes the structure of entirety and transmission more stable and reasonable.
Operation principle of the present utility model：
Superposed moving platen is first turned on, first time side core-pulling is carried out, finished product is due to having in-flanges, therefore meeting
Extract out with core package, then carry out second core pulling, remove the latch being arranged between pulling block and sprue puller, it is same with this
When, back-moving spring traction pulling block is carried out to contract, completes second core pulling, and core pulling twice does not damage finished product, it is ensured that processing
The quality of product.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
