Description
Technical field
The utility model relates to a kind of injection mold parting structure in medical package field.
Background technology
The plastic cement products in medical package field is more, and its architectural feature is more special, and as injector syringe, test tube etc., all there is a deep hole at product middle part, and product is little and thin.For higher production efficiency and lower production cost, this series products is a multi-cavity mold, and full hot flow path side is entered the injection moulding of glue mode.
As shown in Figure 1, current injection mold structure complexity, product die cavity is divided into multiple mold insert compositions, see mold insert A, mold insert B and mold insert C, so both reduced the accuracy of manufacture of mould, increased die manufacturing cost, and mating surface between mold insert A and mold insert B can leave clamp at product surface, affect the presentation quality of product.Mold insert is more simultaneously can produce many Yun Shui dead band, as all led to fortune water cooling in the middle part of mold insert B and mold insert C, greatly reduces fortune water efficiency, for multi-cavity thin wall product, will have a strong impact on its molding cycle.Dismounting difficulty is also a large drawback of such mould, when form removal, need first remove mold insert C, then splits out heat simultaneously and chews and mold insert B, has increased form removal difficulty.Therefore how solving the above-mentioned defect of medical package mould is that those skilled in the art pay close attention to.
Utility model content
The purpose of this utility model is to propose a kind of injection mold parting structure, and it can solve clamp and the inefficient problem of fortune water of existing.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
A kind of injection mold parting structure, rear pattern plate that it comprises front template, coordinate with described front template, be arranged on TOP-TIP and the Yun Shui in described front template and be arranged on the rear mold mold insert in described rear pattern plate, front mould mold insert is installed in described front template, the common product die cavity that forms of described front mould mold insert and described rear mold mold insert, described TOP-TIP is communicated with the product die cavity of front mould mold insert, offers the duct for described fortune water is installed on front mould mold insert.
Preferably, the quantity of front mould mold insert and rear mold mold insert is two, and two front mould mold inserts are symmetrical arranged with the fractionation face of front template, and two rear mold mold inserts are symmetrical arranged with the fractionation face of rear pattern plate, and the fractionation face of front template overlaps with the fractionation face of rear pattern plate.
Further preferred, on front mould mold insert, be provided with screw hole for screw is installed and for the dowel hole of alignment pin is installed, two front mould mold inserts are located by alignment pin, and pass through screw locking.
Further preferred, described TOP-TIP is between two front mould mold inserts.
The utlity model has following beneficial effect:
Not only make to process simple, easy accessibility, and reduced clamp position, improved product appearance quality; Product is without Yun Shui dead band, and fortune water efficiency is high, has shortened the molding cycle of product.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further.
In conjunction with shown in Fig. 1 to Fig. 4, a kind of injection mold parting structure, rear pattern plate 2 that it comprises front template 1, coordinate with described front template 1, be arranged on TOP-TIP 3 in described front template 1 and Yun Shui (Fig. 2 does not draw, can with reference to figure 4), be arranged on the rear mold mold insert 5 in described rear pattern plate 2 and be arranged in described front template 1 front mould mold insert 4 is installed.
Described front mould mold insert 4 and the common product die cavity 100 that forms of described rear mold mold insert 5, described TOP-TIP 3 is communicated with the product die cavity 100 of front mould mold insert 4, offers the duct 43 for described fortune water is installed on front mould mold insert 4.
The front mould mold insert 4 of the present embodiment and the quantity of rear mold mold insert 5 are two, two front mould mold inserts 4 are symmetrical arranged with the fractionation face 10 of front template 1, two rear mold mold inserts 5 are symmetrical arranged with the fractionation face 10 of rear pattern plate 2, and the fractionation face 10 of front template 1 and the fractionation face 10 of rear pattern plate 2 overlap.
On front mould mold insert 4, be also provided with the screw hole 41 for screw is installed and locate by alignment pin for 42, two front mould mold inserts 4 of dowel hole that alignment pin is installed, and by screw locking, assembling is simple, fixing reliable.The TOP-TIP 3 of the present embodiment is between two front mould mold inserts 4.
From the structure of the present embodiment, the product die cavity 100 that front mould mold insert 4 and rear mold mold insert 5 form is monoblock type, assembled without other mold insert, has avoided the appearance of product clamp, has optimized product appearance, realizes seamless injection moulding; Simplify processing simultaneously, easily ensured mould and die accuracy.
In front template 1, two product die cavities 100, for left and right combines, wrap up TOP-TIP 3 to wherein, then pack front template 1 into; When form removal, only two front mould mold inserts 4 need be extracted, separately can complete form removal along fractionation face 10, reach the whole self-contained effect of tearing open, easy accessibility, maintenance cost is low.
Shown in Fig. 4, two front mould mold inserts 4 are monoblock type, and the fortune water that all can distribute around product die cavity 100, without Yun Shui dead band, is shown in fortune water W1, fortune water W2, fortune water W3.Fortune water W1 is oblique tiltedly to be gone out, constantly circulation; The heat that TOP-TIP 3 is passed to product die cavity 100 by fortune water W2, fortune water W3 is taken away, thereby reaches the evenly object of cooling whole front mould mold insert 4, and fortune water efficiency is high, has shortened molding cycle, has improved productivity ratio.
Dress when mould, first packs TOP-TIP 3 into front mould mold insert 4, and packs alignment pin into, and the front mould mold insert 4 that then closes is locked in aggregatesly with screw, pack front template 1 into, completes the assembling of this parting structure.Conventionally this type of mould is a multi-cavity mold, in the time that wherein a chamber needs repairing, only two front mould mold inserts 4 need be taken out from front template 1, and motionless other die cavity, just can take the wherein die cavity in any chamber completely apart and keep in repair, easy accessibility.
When injection moulding, melten gel enters product die cavity 100 by TOP-TIP 3, and because product die cavity 100 is a whole smooth face, assembled without other mold insert, after formed product, appearance is smooth, realizes seamless injection moulding.Product is in cooling procedure, and the inner fortune water distribution of front mould mold insert 4 is even, closely knit, and product die cavity 100 is around without Yun Shui dead band, whole product cooling velocity is accelerated, product just can reach depanning condition in the shorter time, has greatly shortened molding cycle, has improved mould production efficiency.
For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
