Abstract

The utility model provides a demolding structure for an insert at the bottom. By means of the demolding structure, a product provided with a complete outer wall at the upper part of the inside, a notch in the lower part of the inside and a downward special-shaped bulge can be formed once in a mold, so that the production efficiency and the production accuracy are high, and the rejection rate is low. The demolding structure comprises a front mold, a rear mold, a plate A, a plate B and a plate C, wherein a cavity is formed between the front mold and the rear mold, and a to-be-formed product is arranged in the cavity. The demolding structure is characterized in that an inclined mounting cavity is formed in the rear mold, and an inclined block insert is located in the inclined mounting cavity; the upper side part of the inclined block insert is tightly attached to a thin wall of the to-be-formed product, and a T-shaped groove is formed in the lower part of the inclined block insert; springs are uniformly distributed between contact surfaces of the plate B and the plate C; a vertical guide pillar groove is formed below the position, corresponding to the inclined block insert, of the plate B, a guide pillar is arranged in the guide pillar groove, the lower end of the guide pillar is tightly connected with the plate C, and the upper end of the guide pillar adopts a T-shaped structure; and the T-shaped structure is clamped in a corresponding T-shaped groove in the lower part of the inclined block insert.

Description

The demolding structure of a kind of bottom mold insert

Technical field

The utility model relates to the technical field of structures of product mold, is specially the demolding structure of a kind of bottom mold insert.

Background technology

The inner upper of product is complete outer wall, inner bottom band is jagged, and have downward abnormity to protrude, for this product, existing mould can not one-shot forming, all generally first to process complete structure, through following process, form down gap afterwards, its production efficiency is low, and production low precision, percent defective is high.

Summary of the invention

The utility model provides the demolding structure of a kind of bottom mold insert, and it makes inner upper is complete outer wall, and inner bottom band is jagged, and there is the product that downward abnormity protrudes can one-shot forming in mould, make production efficiency high, production precision is high, and percent defective is low.

The demolding structure of a kind of bottom mold insert, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, C plate, described front mould, it between rear mold, is die cavity, in described die cavity, it is product to be formed, it is characterized in that: described rear mold inside has oblique installation cavity, skewback mold insert is positioned at described oblique installation cavity, the upper lateral part of described skewback mold insert is close to the thin-walled of described product to be formed, the bottom of described skewback mold insert has T-shaped groove, described B plate, between the contact-making surface of C plate, be evenly equipped with spring, described B plate corresponding to the below of described skewback mold insert have vertically to guide pillar groove, guide pillar is placed in described guide pillar groove, the lower end of described guide pillar is fastenedly connected described C plate, the upper end of described guide pillar is T-shaped structure, described T-shaped structure is installed in the T-shaped groove in bottom of corresponding described skewback mold insert.

It is further characterized in that: the oblique gradient of the upper lateral part of described skewback mold insert and the gradient of described oblique installation cavity are consistent.

Adopt after structure of the present utility model, the demoulding that makes progress of the moving front mould of A strip, when it departs from B plate completely, after rear mold, under acting force of the spring, the moving rear mold of B strip rises, now the T-shaped structure due to the upper end of guide pillar is installed in the T-shaped groove in bottom of corresponding described skewback mold insert, and the lower end of guide pillar is fastenedly connected described C plate, skewback mold insert is positioned at oblique mounting groove, skewback mold insert is under the active force of oblique mounting groove, rely on T-shaped groove, T-shaped structure is to opposite side parallel sliding, it completes oblique loosing core with respect to product to be formed, it makes inner upper is complete outer wall, inner bottom band is jagged, and there is the product that downward abnormity protrudes can one-shot forming in mould, make production efficiency high, production precision is high, percent defective is low.
