Abstract
An injection molding mold comprises a female mold and a male mold. The female mold comprises a female mold template and a plurality of female mold core blocks disposed in the female mold template. The female mold core block comprises an outer mold core block and an inner mold core block. An inner mold core hole is opened on the outer mold core block, and comprises a female mold molding part and an exhaust part. The inner mold core block comprises a molding end and an exhaust end integratedly connected to the molding end, and comprises an exhaust vent which penetrates through the end surface of the molding end to the outer side surface of the exhaust end. The inner mold core block is accommodated in the inner mold core hole, and the outer side surface of the molding end tightly contacts the inner side wall of the exhaust part; an exhaust gap communicated with the exhaust vent is formed between the outer side surface of the molding end and the inner side wall of the exhaust part which are spaced mutually. The injection molding mold allows smooth exhaust of the air at the female mold side during molding, and ensures the molding quality of a molded product.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of injecting molding die.
Background technology
In injecting molding die, whether exhaust is smooth and easy is the important indicator of weighing mould molding quality quality.If die venting is not smooth, then can cause distortion of moulding product outward appearance and undersize, also might make the inside of moulding product have bubble residual, have a strong impact on the quality of moulding product.
Existing injecting molding die often only carries out vent design in male model one side, and has ignored the vent design of master mold one side, and the part that causes taking shape in the moulding product of master mold side is out of shape and undersize because of outward appearance easily, and perhaps bubble is residual and influence its quality.In addition, the exhaust effect of existing injecting molding die is also undesirable, therefore is difficult to guarantee the Forming Quality of moulding product.
Summary of the invention
In view of this, be necessary to provide a kind of exhaust smooth and easy injecting molding die with the Forming Quality that guarantees the moulding product.
A kind of injecting molding die comprises that a master mold and one cooperate the male model with the moulding injection-molded article with described master mold, and described master mold comprises a master mold template and a plurality of mother module core piece that is arranged in the described master mold template.Described mother module core piece comprises an outer die piece and an interior die piece that is arranged in the described outer die piece.Described outer die piece offers an interior die hole, and described interior die hole comprises coaxial a master mold forming part and an exhaust portion.The die piece comprises a forming ends and an exhaust end that links to each other with described forming ends one in described, and described interior die piece comprises the steam vent that penetrates into described exhaust end lateral surface from described forming ends end face.The die piece is contained in the described interior die hole in described, and the lateral surface of described forming ends closely contacts with the madial wall of described exhaust portion, and the space forms the exhaust clearance that communicates with described steam vent between the lateral surface of described exhaust end and the madial wall of described exhaust portion.
Steam vent and exhaust clearance that described injecting molding die cooperatively interacts in the design of described master mold one side can be so that be positioned at the smooth and easy discharge of air of described master mold one side during moulding, guarantee to take shape in the Forming Quality of part of the moulding product of described master mold one side.Simultaneously, described steam vent and exhaust clearance cooperate the design of exhaust to compare prior art can be so that exhaust be more smooth and easy, with the quality of further raising moulding product.
