Abstract
The utility model discloses a kind of pre- drawing mechanism of die casting core pulling, is mainly used for the elongated core needle demoulding inside mould core pulling.The structure includes：Slide, pre- extraction spring and sliding block are spacing after slide, type pin before wedging by fixed die block, type pin.Before molding, core pulling oil cylinder pushing core pulling enters precalculated position, during molding, wedge block contacts with slide and promotes core pin slide to move forward, slide contained spring is subject to compression so that wherein core pin reaches precalculated position at this time, carry out the action molten aluminum cladded type core needle such as injection and solidify, during die sinking, wedging by fixed die block progressively disengages slide, slide is resetted before spring release by pressure pressure, slide drives core pin to be moved rearwards core pin and departs from product, reach pre- extraction effect during reset, then molds core pulling oil cylinder in place and carries out oil-filled extraction core pulling.Core pin is first extracted out before this process core pulling, is reduced product to the package power of whole core pulling, is reached the stripping result extracted out in advance.
Description
Technical field
The present invention relates to die casting technical field, specifically a kind of pre- drawing mechanism of die casting core pulling.
Background technology
Product structure determines structure of cast die.As product structure makes rapid progress to adapt to the performance of product, production
The complication of product structure also determines mould structure form, and there is longer core pin in large-scale step pulled core structure, by
Complexity in the structure of product local location core pin, occurs part in normal production and is difficult to demould or is molded undesirable
Defect.The present invention, which proposes, solves the problems, such as a kind of this effective linkage.
Utility model content
The present invention is directed to above-mentioned problem, there is provided a kind of pre- drawing mechanism of die casting core pulling.
The present invention to achieve the above object, takes following technical scheme to be achieved：
A kind of pre- drawing mechanism of die casting core pulling, it is characterised in that before wedging by fixed die block, type pin after slide, type pin
Slide, pre- extraction spring and sliding block are spacing.
Preferably, described to install wedge block additional in cover half, dynamic model elongated core needle is fixed between preceding slide and rear slide, slide
Inside core pulling, mechanical pulled core structure is formed with wedging by fixed die block.
Preferably, linked between the slide and core pulling using spring.
Preferably, it is spacing to extract increase screw fixation above guide rail out in advance for the dynamic model.
In use, during molding, wedging by fixed die block and rear slide contact of incline plane simultaneously promote slide to move forward, at this time in slide
Portion's spring is subject to compression so that wherein core pin reaches precalculated position, and then progress injection etc. acts molten aluminum cladded type core needle and coagulates
Gu during die sinking, wedging by fixed die block progressively disengages slide, slide is resetted before spring release by pressure pressure, and when reset is slided
Seat drives, core pin is moved rearwards core pin and departs from product, reaches pre- extraction effect, then molds core pulling oil cylinder in place and filled
Oil extraction core pulling.
Beneficial effects of the present invention are as follows：The pre- drawing mechanism of the utility model is simple, easy to use, is not influencing mould just
Often use, local type core needle can extract out in advance, the package power of product on core pulling face to core pulling can effectively be reduced, beneficial to core pulling
Process smoothly extracts core pulling out and reduces sticking to mould situation.

Embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing.
Core pulling position is shown referring to Fig. 1：Core pulling position in a kind of pre- drawing mechanism of die casting core pulling, cover half 1,
Core-pulling slide block 2, core pulling stent oil cylinder 3, dynamic model 4.
Slided after showing pre- withdrawn position and structure diagram, including cover half 1, pre- extraction front-slider 2, pre- extraction referring to Fig. 2
Block 3, pre- extraction wedge block 4, extract spacing 5, core pulling stent oil cylinder, dynamic model 7, core-pulling slide block 8, spring 9, elongated core needle 10 out in advance.
Show pre- drawing mechanism embodiment schematic diagram referring to Fig. 3, Fig. 3-1 shows, molds state, wedging by fixed die block 2 with it is pre-
Slide 5 after extraction, rear slide 5 fix elongated core needle 8 together with preceding slide 6, between fixed spring 7,7 compression elongated of spring at this time
Core needle 8 reaches predetermined state, and wedge block 2 contacts and promotes slide 5 to move forward during molding, and slide contained spring is pressed at this time
Contracting make it that wherein core pin reaches precalculated position, that is, molds state, carries out the action molten aluminum cladded type core needle such as injection afterwards and simultaneously coagulates
Gu；Fig. 3-2 shows that die opening state, wedge block 2 leaves slide 5, and slide 5,6 and core pin 7 are subject to the reply of spring pressure to make
With being moved rearwards, core pin 7 departs from product, and slide 5,6 stops movement, i.e. die opening state after being moved to spacing 3, this process is realized
The demoulding of core pulling local location acts on, and reaches the smooth demoulding, reduces the effect of core pulling position package power.
Show the spring structure schematic diagram of the pre- drawing mechanism of the utility model referring to Fig. 4, sliding block is spacing 1, core-pulling slide block 2,
Slide 4, pre- extraction spring 5, elongated core needle 6 before slide 3, pre- extraction after pre- extraction.
Only as described above, is only the preferred embodiments of the invention, when the model that implementation of the invention cannot be limited with this
Enclose, i.e., generally according to simple equivalent changes and modifications made by the content described in the claims in the present invention and description of the invention,
All it is still covered by the claims of the invention.Searched in addition, summary part and title are intended merely to auxiliary patent document
Seek and being used, be not used for limiting the interest field of the present invention.
