Abstract

The utility model discloses an injection mould, which comprises a front mould, a rear mould, an injection port and an injection runner. The injection port is recessed to the inside of the injection mould so that the length of the injection runner is shorter relatively. The length of the injection runner is shorter on the premise that moulds are in the same size since the depth of the injection port of the injection mould recessed to the inside of the injection mould is increased. Accordingly, when raw materials which are heated to melt flow through the shorter injection runner, the difficulty in injection molding is decreased and waste of the raw materials is reduced simultaneously.

Description

Injection mold
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of injection hole to mould and has carried out improved injection mold.
Background technology
Injection mold belongs to the injection mo(u)lding field, is used to produce in batches the product or the parts of different shape, is meant that particularly the raw material that melt being heated in high-pressure injection is gone into die cavity, behind cooling curing, obtain final formed product.Process of injection molding is broadly divided into following 6 stages " matched moulds-injection-pressurize-cooling-die sinking-goods take out ", and above-mentioned technology is carried out repeatedly, just can continuously produce shaped article.In above-mentioned technology, injection stage generally is to inject in the die cavity with the completion injection process with injection molding channel through the injection hole of mould through will the be heated raw material that melt of injection device.In above-mentioned injection process, the structural design of injection hole and injection molding channel can produce considerable influence to the quality of final injection molding product.As shown in Figure 2; It among the figure structural design that injection hole and injection molding channel adopted in the existing injection mold; This structural design mainly comprises injection hole 11 and injection molding channel 12, and the raw material of the thawing of being heated during injection get into die cavity through the injection hole 11 of mould with injection molding channel 12 backs.But when adopting this kind structural design; Because injection hole 11 depressions are for cylindrical shape and cave in less; Under the identical situation of mould size; The length of injection molding channel 12 is longer relatively, and the raw material that melt that are heated not only can make the difficulty of injection moulding increase through long injection molding channel 12, and can cause raw-material waste.
In sum, problem demanding prompt solution is need the injection hole 11 of injection mold be improved to overcome above-mentioned defective with injection molding channel 12.
Summary of the invention
The utility model technical problem to be solved is, a kind of injection mold is provided, and its injection hole and injection molding channel to injection mold improves, and makes injection molding channel length shorten relatively, has reached the effect of being convenient to injection moulding and having saved the raw material material.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of injection mold, and this mould comprises: front mould, back mould, injection hole and injection molding channel, wherein; Mould inside forms die cavity after said front mould and the back die combination; Said injection molding channel is communicated with the die cavity of said injection hole and mould inside formation, and in addition, said injection hole is absorbed in mould inside so that the length of said injection molding channel shortens relatively.
Further, in the described injection mold, the junction of said injection hole and injection molding channel is arc shape.
Further, in the described injection mold, the top of said injection hole is cylindrical.
The utility model has the advantages that the injection hole of the utility model is absorbed in mould inside, the top of injection hole is cylindrical, and the junction of bottom and injection molding channel is arc shape.The injection hole that has increased this injection mold through above-mentioned improvement is absorbed in the degree of depth of mould inside, thereby under the identical situation of mould size, makes injection molding channel length shorten relatively.Therefore, the raw material that melt when being heated have not only reduced the difficulty of injection moulding when passing through short injection molding channel, and have reduced raw-material waste.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model injection mold;
Fig. 2 is the structural representation of injection hole and injection molding channel in the existing injection mold;
Fig. 3 is the structural representation of injection hole and injection molding channel in the injection mold of the utility model.
The specific embodiment
For further disclosing the technical scheme of the utility model, be described with reference to the accompanying drawings the embodiment of the utility model now.
Fig. 1 is the overall structure sketch map of the utility model injection mold; Fig. 2 is the structural representation of injection hole and injection molding channel in the existing injection mold, and Fig. 3 is the structural representation of injection hole and injection molding channel in the injection mold of the utility model, wherein; Comprise: front mould 10, back mould 20, injection hole 11 and injection molding channel 12; Wherein, said front mould 10 makes up the back mould insides with back mould 20 and forms die cavitys, and said injection molding channel 12 is communicated with the die cavity of said injection hole 11 and mould inside formation; In addition, said injection hole 11 is absorbed in mould inside so that the length of said injection molding channel 12 shortens relatively.Particularly, said injection hole 11 can adopt arc shape with the junction of injection molding channel 12, and cylindrical shape can be adopted in the top of said injection hole 11.
Action situation when the utility model actual motion being described below in conjunction with Fig. 1, Fig. 2 and Fig. 3:
During work, inject said injection hole 11 through the injection device raw material that melt that will be heated, the raw material in the said injection hole 11 get into through said injection molding channel 12 in the die cavity of injection molds and accomplish injection process.In the utility model, through improving the structure of injection hole 11 and injection molding channel 12, the injection hole 11 that has increased this injection mold is absorbed in the degree of depth of mould inside, thereby under the identical situation of mould size, makes injection molding channel 12 length shorten relatively.Thereby the raw material that melt when being heated have reduced the difficulty of injection moulding when passing through short injection molding channel 12, reduced raw-material waste.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
