Abstract
The utility model belongs to the technical field of molds, and provides a gas assisted structure of a mold. The gas assisted structure of the mold comprises a gas assisted needle and a gas inlet pipe communicated with the gas assisted needle, wherein a seal ring for sealing gas is arranged in a contact position of the gas assisted needle, a cavity and a mold base. According to the gas assisted structure of the mold, the gas assisted structure is adopted to blow toward a thick-walled position of a product, so that a hollow part is formed in the thick-walled position of the product, and defects of shrinkage and the like are overcome; and the gas assisted structure is simple in structure, convenient to manufacture and high in production efficiency.
Description
Technical field
The utility model relates to mould accessory, relates in particular to a kind of auxiliary structure of gas of mould.
Background technology
Some industrial products, for strengthening its intensity and toughness, require the wall thickness at local enhancement product, but the appearance requirement of product is extremely strict again, can not have the defects such as shrink.This series products is to Design of Dies and the very challenging property of injection mo(u)lding.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of auxiliary structure of gas of mould is provided.
For realizing above object, the technical solution adopted in the utility model is:
The auxiliary structure of gas of mould, comprises the auxiliary pin of gas and the air inlet pipe being communicated with it, is provided with the sealing ring of sealing gas in the auxiliary pin of gas and mould jade, mold base contact position.
The beneficial effects of the utility model: adopt the auxiliary structure of gas to blow to product wall thickness place, make product wall thickness condemn into hollow bulb, avoided the defects such as shrink; Simple in structure, easily manufactured, production efficiency is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is according to the auxiliary structure matched moulds of the gas of a kind of mould of the utility model preferred embodiment view.
The specific embodiment
Referring to Fig. 1, the auxiliary structure of a kind of gas of mould, comprises the auxiliary pin 3 of the gas blow pipe 1, the gas that interconnect, and the auxiliary pin 3 of gas extend into the heavy wall place of goods 4.The auxiliary pin 3 of gas, mould jade, mold base sealing gas are completed by sealing ring 2, and air inflow carries control valve by injection machine and completes.
In injection moulding, by glue-feeder 5, undertaken, after completing, gas is blown into from gas blow pipe 1, allow goods 4 form hollow bulb 41, can effectively avoid occurring the defects such as shrink.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make concrete change or change and all belong to protection domain of the present utility model.
