Description

A kind of injection mold with vapour-pressure type with mechanical combination ejecting mechanism

Technical field

The utility model is related to injection mold technical field, more particularly to a kind of that there is vapour-pressure type to be ejected with mechanical combine The injection mold of mechanism.

Background technology

In articles for daily use and packing articles, some deep chamber plastic cement parts are often had, if using traditional ejection side Method, has following shortcoming：Due to ejecting distance greatly, it is necessary to bigger injection machine；Need to design substantial amounts of thimble, due to top The arrangement of pin, it more difficult to design cooling water channel, causes longer injection cycle, reduces production efficiency；Easily cause product top white Or thimble trace, cause product rejection.

Utility model content

The technical problems to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, and one kind of proposition, which has, to be combined The injection mold of vapour-pressure type and mechanical ejecting mechanism.

It is achieved through the following technical solutions above-mentioned purpose：

The utility model provides a kind of with vapour-pressure type and the mechanical injection mold for combining ejecting mechanism, including male model The mother module core, push rod and promotion push rod that benevolence, sliding block, the male die core and the sliding block form die cavity are moved along die sinking direction Pushing meanss, the male die core contains through hole, and the push rod is placed among the through hole, through hole hole head at the top of the male die core For trapezoidal hole head, the push rod includes head and shaft, and the head is trapezoidal head and can be with the through hole trapezoidal hole head Laminating, the push rod is arranged to slide along die sinking direction with respect to male die core, and empty avoiding is provided between the through hole and the shaft Groove, the shaft contains air discharge duct close to the position of head, and the avoiding hollow groove is communicated with the air discharge duct, and the male die core contains Air admission hole, the air admission hole is communicated with the avoiding hollow groove, provided with close between the male die core bottom through-hole hole head and the push rod Sealing.

It is preferred that, the trapezoidal head is formed with male die core, mother module core and sliding block formation moulding die cavity, the head Die cavity in the middle part of moulding.

It is preferred that, the shaft is cylinder, and the shaft is uniform with annular array provided with four close to the position of head The air discharge duct of arrangement.

The beneficial effects of the utility model are：The ejection knot that the utility model is combined using compressed air and mechanically Structure.Wherein compressed air has two effects：One is when avoiding the plastic part from being ejected, to be produced between plastic part and male die core Vacuum, two be the inside for acting on plastic part, assistant ejector pin ejection plastic part.By above structure, it can use smaller Injection machine, reduce injection cost, simultaneously because without using thimble, more coolings can be equably arranged in male die core Water route, the temperature of male die core can be balanced well, accelerate the cooling of male die core and plastic part, reduce cool time, improved Production efficiency, due to eliminating substantial amounts of thimble, also improves and pushes up white or thimble trace, yields is improved, so as to reduce Injection mold manufacturing cost.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing：

It is a kind of with vapour-pressure type and the mechanical injection mold for combining ejecting mechanism, including caster shown in Fig. 1 to Fig. 5 （Figure is not marked）, mother module core 1, male template 2, male die core 3, sliding block 4, push rod 5 and promote push rod along the die sinking promotion moved of direction Device 6, the male die core 3 contains through hole 31, and the push rod 5 is placed among the through hole 31, through hole 31 at the top of the male die core Hole head is trapezoidal hole head, and the push rod 5 includes head 51 and shaft 52, and the head 51 is trapezoidal head and can led to described The laminating of hole 31 trapezoidal hole head, the push rod 5 be arranged to can relative male die core 3 along the slip of die sinking direction, the through hole 31 with it is described Avoiding hollow groove 7 is provided between shaft 52, the shaft 52 contains air discharge duct 53, the avoiding hollow groove 7 and institute close to the position of head 51 State air discharge duct 53 to communicate, the male die core 3 contains air admission hole 32, the air admission hole 32 is communicated with the avoiding hollow groove 7, the male model Seal 8 is provided between the hole of benevolence bottom through-hole 31 head and the shaft 52.

It is preferred that, head 51 is formed with male die core 3, mother module core 1 and the formation moulding die cavity of sliding block 4, the head 51 Die cavity be the middle part of moulding 9.

It is preferred that, the shaft 52 is cylinder, and the shaft 52 is close to the position of head 51 provided with four with circular array Arrange the air discharge duct 53 uniformly arranged.

It is preferred that, the pushing meanss 6 include push rod fixed plate 61 and injection machine push rod 62, the push rod 5 with it is described Push rod fixed plate 61 is fixedly connected, and the injection machine push rod 62 is abreast arranged on the push rod fixed plate 61 with the push rod 5 Lower section.

It is described above that not this new technical scope is imposed any restrictions, it is all according to the utility model technical spirit to On embodiment any modification, equivalent variations and the modification made, in the range of still falling within this new technical scheme.
