Abstract

The invention provides a slant core pulling structure of a front mould, which ensures that a product with a hole in a slant direction can be moulded in one step at high processing efficiency. The slant core pulling structure comprises a panel, a water gap plate, a plate A, a plate B, a front mould and a rear mould, wherein a cavity formed between the front mould and the rear mould is a mould cavity. The slant core pulling structure is characterized in that a slant insert penetrates through the front mould and then presses against on a parting surface between the front mould and the rear mould, the slant insert is located inside a slant guide rail of the front mould, the upper end of the slant insert is connected with a connection block in a fastening manner through a bolt, the connection block, the bolt and the slant insert are located on the same center line, the connection block and the bolt are located in a slant guide rail groove of the plate A, a hook hole is formed at one end of the connection block, a mechanical drag hook is connected with the water gap plate in a fastening manner, an outwards convex hook end of the mechanical drag hook is embedded in the hook hole, and a motion cavity of the mechanical drag hook is formed in the plate A.

Description

The front mould structure of tiltedly loosing core

Technical field

The present invention relates to the technical field of structures of product mold, be specially the front mould structure of tiltedly loosing core.

Background technology

After the outward appearance of the general first moulding product of mould of the existing oblique product that has a hole, carry out the processing of oblique hole again, need post forming, working (machining) efficiency is low.

Summary of the invention

The invention provides the front mould structure of tiltedly loosing core, it makes that the oblique product that has a hole can one-shot forming, the working (machining) efficiency height.

The front mould structure of tiltedly loosing core, it comprises panel, mouth of a river plate, the A plate, the B plate, front mould, back mould, described front mould, cavity between the back mould is a die cavity, it is characterized in that: oblique mold insert is pressed on described front mould after running through described front mould, the die joint of back intermode, described oblique mold insert is positioned at the oblique guide rail of described front mould, the upper end of described oblique mold insert connects contiguous block by bolted, described contiguous block, bolt, oblique mold insert is positioned at same center line, described contiguous block, bolt is positioned at the slant rail groove of described A plate, one end of described contiguous block has dog hole, the machinery drag hook is fastenedly connected described mouth of a river plate, the evagination hook end of described mechanical drag hook is embedded in the described dog hole, and described A plate has the movable chamber of mechanical drag hook.

It is further characterized in that: the bolt of described contiguous block and described oblique mold insert partly is set with die springs, and the evagination hook end of described mechanical drag hook gos deep into the bolt head lower surface that described bolt is being pressed in its upper surface behind the dog hole.

After adopting structure of the present invention, during the demoulding, panel rises, and mouth of a river plate rises, driving mechanical drag hook rises, the machinery drag hook drives the contiguous block be in the slant rail groove and moves obliquely, and then drives oblique mold insert and move obliquely, finishes the oblique demoulding until oblique mold insert, the externally drive rising down of lift structure of A plate, front mould afterwards, finish the demoulding, it makes that the oblique product that has a hole can one-shot forming, the working (machining) efficiency height.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

See Fig. 1, it comprises panel 1, mouth of a river plate 2, A plate 3, B plate 16, front mould 4, back mould 5, front mould 4, cavity between the back mould 5 is a die cavity, in the die cavity is product 6, oblique mold insert 7 is pressed on front mould 4 after running through front mould 4, the die joint that back mould is 5, oblique mold insert 7 is positioned at the oblique guide rail 8 of front mould 4, the upper end of oblique mold insert 7 is fastenedly connected contiguous block 10 by bolt 9, contiguous block 10, bolt 9, oblique mold insert 7 is positioned at same center line, contiguous block 10, bolt 9 is positioned at the slant rail groove 11 of A plate 3, one end of contiguous block 10 has dog hole, machinery drag hook 12 is fastenedly connected mouth of a river plate 2, the evagination hook end 13 of machinery drag hook 12 is embedded in the dog hole, and A plate 3 has the movable chamber 14 of mechanical drag hook 12.The bolt that contiguous block 10 and oblique mold insert are 7 partly is set with die springs 15, and the evagination hook end 13 of mechanical drag hook 12 gos deep into the bolt head lower surface that bolt 9 is being pressed in its upper surface behind the dog hole.

Its operation principle is as follows: during matched moulds, die springs 15 oblique mold inserts 7 are pressed on the die joint of front mould 4,5 of the moulds in back; During the demoulding, panel 1 rises, mouth of a river plate 2 rises, drive mechanical drag hook 12 and rise, mechanical drag hook 12 drives the contiguous blocks 10 that are in the slant rail groove 11 and moves obliquely, and then drives oblique mold insert 7 and move obliquely, finish the oblique demoulding until oblique mold insert 7, the demoulding is finished in the externally drive rising down of lift structure (belong to existing mature structure, do not draw among the figure) of A plate 3, front mould 4 afterwards.

Claims
