The utility model discloses a cover half mold insert and the cooperation of first movable mould mold insert, second movable mould mold insert, third movable mould mold insert to thereby ejecting buckle through mold insert spring ejection third movable mould mold insert, better solution the problem of article back-off deformation, better solution shell buckle easily turn up the deformation, lead to the bad problem of serious assembly of product.

Description

Die for solving product back-off deformation

Technical Field

The utility model relates to an injection mold especially relates to a solve mould that product back-off warp.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. As shown in fig. 1, in the injection molding of plastic products 10, some of the buckles 101 on the products 10 are easy to turn outwards and deform, resulting in serious poor assembly of the products 10, and therefore, a mold for solving the deformation reverse is urgently needed by the manufacturers.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a solve mould that product back-off warp.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a solve the mould that the product back-off warp, including fixed die plate, movable mould board, movable mould backing plate, fixed die insert, first movable mould insert, second movable mould insert, third movable mould insert, insert spring; the fixed die plate and the movable die plate are arranged oppositely, the movable die plate is fixed on the movable die base plate, the upper end of the fixed die insert is fixed on the fixed die plate, the first movable die insert and the second movable die insert are fixed on the movable die plate, the second movable die insert is close to the side wall of the first movable die insert, the lower part of the third movable die insert is movably sleeved on the movable die plate, the upper end of the third movable die insert is opposite to the lower end of the fixed die insert, a spring gap of the insert is sleeved in a spring hole of the movable die base plate, and two ends of an insert spring are respectively abutted against the lower end of the third movable die insert and a spring hole of the movable die base plate.

After the scheme of the above, because the utility model discloses a fixed die plate, movable mould board, movable mould backing plate, cover half mold insert, first movable mould mold insert, second movable mould mold insert, third movable mould mold insert, the mold insert spring, through the cooperation of cover half mold insert and first movable mould mold insert, second movable mould mold insert, third movable mould mold insert to thereby ejecting buckle of third movable mould mold insert is popped up through the mold insert spring, better solution the problem of article back-off deformation, better solution shell buckle easily turns up the deformation, lead to the serious bad problem of assembly of product.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 2-6, the utility model relates to a solve mould of product back-off deformation, including fixed die plate 1, movable mould board 2, movable mould backing plate 3, cover half mold insert 4, first movable mould mold insert 5, second movable mould mold insert 6, third movable mould mold insert 7, mold insert spring 8.

The fixed die plate 1 and the movable die plate 2 are arranged oppositely, the movable die plate 2 is fixed on the movable die base plate 3, the upper end of the fixed die insert 4 is fixed on the fixed die plate 1, the lower end of the fixed die insert 4 extends to the movable die plate, the first movable die insert 5 and the second movable die insert 6 are both fixed on the movable die plate 2, the second movable die insert 6 is close to the side wall of the first movable die insert 1, the lower part of the third movable die insert 7 is movably sleeved on the movable die plate 2, the upper end of the third movable die insert 7 is opposite to the lower end of the fixed die insert 4, the insert spring 8 is sleeved in a spring hole 31 of the movable die base plate 3 in a clearance mode, and two ends of the insert spring 8 are respectively abutted against the lower end of the third movable die insert 7 and the spring hole 31.

The utility model discloses a theory of operation:

the utility model discloses easily turn up local make-up internal buckling anti-deformation mode with the product buckle, after the board compound die, utilize the internal buckling anti-deformation space injection moulding that cover half mold insert 4 and first movable mould mold insert 5, second movable mould mold insert 6, third movable mould mold insert 7 are constituteed, reduce the product deflection of turning up to utilize mold insert spring 8 spring ejection third movable mould mold insert 7, make its buckle 101 (as shown in figure 1) of ejecting product 10.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
