Abstract
The invention provides a demoulding structure for a bottom mold insert. With the demoulding structure, one shot forming of a product in a die can be realized, wherein the upper part of the interior of the product is an intact outer wall, and the lower part of the interior of the product has a gap and a downward special-shaped bump; and the demoulding structure enables high production efficiency, high production precision and a low rejection rate to be obtained. The demoulding structure comprises a front mold, a rear mold, a plate A, a plate B and a plate C, wherein a mold cavity is located between the front mold and the rear mold, and a to-be-molded product is arranged in the mold cavity. The demoulding structure is characterized in that the interior of the rear mold is provided with an oblique installation cavity, an inclined block mold insert is located in the oblique installation cavity, the upper side part of the inclined block mold insert closely abuts against the thin wall of the to-be-molded product, the lower part of the inclined block mold insert is provided with a T-shaped groove, springs are uniformly distributed between contact surfaces of the plate B and the plate C, the plate B is provided with a vertical guide pillar groove at a corresponding position below the inclined block mold insert, a guide pillar is arranged in the guide pillar groove, the lower end of the guide pillar is fixedly connected with the plate C, the upper end of the guide pillar is a T-shaped structure, and the T-shaped structure is snapped in the corresponding T-shaped groove at the lower part of the inclined block mold insert.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be 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 the production low precision, percent defective is high.
Summary of the invention
The invention provides the demolding structure of a kind of bottom mold insert, 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, the 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, the A plate, the B plate, the 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, the 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 the 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.
After adopting structure of the present invention, the demoulding that makes progress of the moving front mould of A strip, when it breaks away from the B plate fully, 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, the skewback mold insert is positioned at oblique mounting groove, the skewback mold insert is under the active force of oblique mounting groove, rely on T-shaped groove, T-shaped structure is to the 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, the production precision is high, percent defective is low.
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention;
Fig. 2 is the C-C cutaway view partial structurtes schematic diagram of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2, it comprises front mould 1, rear mold 2, A plate 3, B plate 4, C plate 5, front mould 1, it between rear mold 2, is die cavity, in die cavity, it is product 6 to be formed, rear mold 2 inside have oblique installation cavity 7, skewback mold insert 8 is positioned at oblique installation cavity 7, the upper lateral part 9 of skewback mold insert 8 is close to the thin-walled of product 6 to be formed, the bottom of skewback mold insert 8 has T-shaped groove 10, B plate 4, between the contact-making surface of C plate 5, be evenly equipped with spring 11, B plate 4 corresponding to the below of skewback mold insert 8 have vertically to guide pillar groove 12, guide pillar 13 is placed in guide pillar groove 12, the lower end of guide pillar 13 is fastenedly connected the C plate, the upper end of guide pillar 13 is T-shaped structure 14, T-shaped structure 14 is installed in the T-shaped groove 10 in bottom of corresponding skewback mold insert 8.The oblique gradient of the upper lateral part 9 of skewback mold insert 8 is consistent with the gradient of oblique installation cavity 7.
