Abstract

The utility model provides an oblique core-pulling mechanism of a front die, which can once form oblique products with holes and achieve high processing efficiency. The oblique core-pulling mechanism comprises a panel, a water gap plate, a plate A, a plate B, the front die and a back die, wherein, a hollow cavity between the front die and the back die is a mold cavity. The oblique core-pulling mechanism is characterized in that an oblique insert penetrates through the front die and then presses a parting surface between the front die and the back die, and the oblique insert is positioned in an oblique guide rail of the front die; the upper end of the oblique insert is connected with a connecting block in a fastened manner through a bolt; the connecting block, the bolt and the oblique insert are positioned on the same center line; the connecting block and the bolt are positioned in an oblique guide rail slot of the plate A; a hook hole is formed at one end of the connecting block; a mechanical draw hook is connected with the water gap plate in a fastened manner; an outer convex hook end of the mechanical draw hook is embedded in the hook hole; and a moving cavity of the mechanical draw hook is formed on the plate A.

Description

A kind of front mould structure of tiltedly loosing core

Technical field

The utility model relates to the technical field of structures of product mold, is specially a kind of 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 utility model provides a kind of front mould structure of tiltedly loosing core, and it makes that the oblique product that has a hole can one-shot forming, and working (machining) efficiency is high.

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

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

After adopting the structure of the utility model, during the demoulding, panel rises; Mouth of a river plate rises, and drives mechanical drag hook and rises, and mechanical drag hook drives the contiguous block that is in the slant rail groove and moves obliquely; And then drive oblique mold insert and move obliquely, accomplish the oblique demoulding until oblique mold insert, afterwards A plate, front mould externally the drive of lift structure rise down; Accomplish the demoulding, it makes that the oblique product that has a hole can one-shot forming, and working (machining) efficiency is high.

Description of drawings

Fig. 1 is the structural representation of the utility model.

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, and the cavity between front mould 4, the back mould 5 is a die cavity; In the die cavity is product 6; Oblique mold insert 7 runs through the die joint that is pressed on 5 of front moulds 4, back mould behind the front mould 4, and oblique mold insert 7 is positioned at the oblique guide rail 8 of front mould 4, and the upper end of oblique mold insert 7 is fastenedly connected contiguous block 10 through bolt 9; Contiguous block 10, bolt 9, oblique mold insert 7 are positioned at same center line; Contiguous block 10, bolt 9 are positioned at the slant rail groove 11 of A plate 3, and an end of contiguous block 10 has dog hole, and mechanical 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 following: 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, and 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; Accomplish the oblique demoulding until oblique mold insert 7; The demoulding is accomplished 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.
