Abstract
The utility model belongs to the technical field of moulds and provides a product deformation prevention structure in an injection mould. The structure comprises a first mould plate, a second mould plate and an injection moulding flow channel. A movement space is reserved between the first mould plate and the second mould plate, an insert is arranged in the movement space, a pressure space is reserved between the insert and the first mould plate, and a product is moulded in injection mode on the insert after being injected in the injection moulding flow channel. The product deformation prevention structure further comprises a pressure maintaining mechanism which can affect the insert to adjust the size of the pressure space so as to enable the product to be evenly stressed. The product deformation prevention structure in the injection mould has the advantages that the produced injection moulding product has no stress residue and is not provided with sink marks. Due to the fact that during pressure maintenance, the stress on the product in all directions is the same, inner stress is reduced to be the lowest, strength of the product is ensured while deformation of the product is reduced, and manufacture cost is saved.
Description
Technical field
The utility model belongs to technical field of mold, relates to the anti-product distressed structure in a kind of injection mold.
Background technology
When injection moulding filling product, all to carry out the pressurize operation, closely water end, when the injection machine pressurize, because pressure loss is little; So pressure is bigger, far watering end, when the injection machine pressurize; Because it is pressure loss is big,, different owing to pressure on same product like this so pressure is less; Thereby it is inconsistent to cause product to shrink, and causes product distortion wing bent, and product has distortion wing song will certainly cause the assembling difficulty slightly; Perhaps influence its appearance and use, so just need logical baking to proofread and correct or the tool correction operation, just have more one procedure so aborning; Not only can increase manufacturing cost, and proofread and correct or the product of tool correction is used of long durationly, also can produce secondary deformation through overbaking.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art, and provide a kind of when pressurize, make pressure everywhere all with, reduce the product distortion, the anti-product distressed structure in the high injection mold of product strength.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the anti-product distressed structure in a kind of injection mold; Comprise first template, second template and injection molding channel; Has space between described first template and second template; In space, be provided with and insert, insert and first template between have the pressure spacing, on inserting after the injection molding channel injection moulding, inject product; It is characterized in that: this distressed structure also includes pressure-keeping mechanism, makes the product pressure even thereby described pressure-keeping mechanism can act on the rise seamless power spacing size of inserting.
The measure of taking for the optimization such scheme specifically comprises:
In the anti-product distressed structure in above-mentioned a kind of injection mold; Described pressure-keeping mechanism comprises angled-lift splits and cylinder; Angled-lift splits upwards withstands and inserts; In space, be provided with slideway, angled-lift splits is erected on the slideway, thereby angled-lift splits can side-to-side movement drive the adjustment pressure spacing size that moves up and down of inserting under the effect of cylinder.
In the anti-product distressed structure in above-mentioned a kind of injection mold, be respectively arranged with upper mounted plate and bottom plate on described first template and second template.
Compared with prior art, the advantage of the utility model is that the injecting products of being produced is unstressed residual, and product does not have shrink mark; Because each of product be to stressed identical during pressurize, internal stress is reduced to minimum, when reducing the product distortion; Also guarantee the intensity of product, saved manufacturing cost.
Description of drawings
Fig. 1 is the overall structure sketch map of the anti-product distressed structure in this injection mold;
Structural representation when Fig. 2 is the injection moulding of the anti-product distressed structure in this injection mold;
Structural representation when Fig. 3 is the pressurize of the anti-product distressed structure in this injection mold.
Among the figure, first template 1; Second template 2; Injection molding channel 3; Space 4; Insert 5; Angled-lift splits 6; Cylinder 7; Slideway 8; Product 9; Upper mounted plate 10; Bottom plate 11; Pressure spacing T; Pressure-keeping mechanism A.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
Like Fig. 1, Fig. 2 and shown in Figure 3; Anti-product distressed structure in a kind of injection mold; Comprise first template 1, second template 2 and injection molding channel 3, install and fix for ease, be respectively arranged with upper mounted plate 10 and bottom plate 11 on first template 1 and second template 2; Have space 4 between first template 1 and second template 2, in space 4, be provided with and insert 5, inserting has pressure spacing T between 5 and first template 1, injects product 9 through inserting after injection molding channel 3 injection mouldings on 5.
The topmost structure of this distressed structure is also to include pressure-keeping mechanism A; Here the main effect of pressure-keeping mechanism A is when injecting products 9, to guarantee to make the far-end of injection moulding and near-end all keep constant compression force; Pressure-keeping mechanism A comprises angled-lift splits 6 and cylinder 7; Angled-lift splits 6 upwards withstands and inserts 5; In space 4, be provided with slideway 8, angled-lift splits 6 is erected on the slideway 8, thereby thereby angled-lift splits 6 can side-to-side movement drives the 5 adjustment pressure spacing T sizes that move up and down of inserting and makes product 9 pressures even under the effect of cylinder 7.
During work at first cylinder 7 drive angled-lift splits 6 with regard to rollback and move right, 5 move downward thereby make to insert, through injection molding channel 3 product 9 is injection-moulded in and inserts on 5; Pressure spacing T size is greater than the thickness of product 9 end-state like this; Then in order to guarantee the pressure of far-end, cylinder 7 is advanced drive angled-lift splits 6 to left movement, 5 move upward thereby make to insert; The pressure spacing T that inserts like this between 5 and first template 1 just diminishes; And in time adjust, thereby guarantee to make the far-end of injection moulding and near-end all keep constant compression force, accomplish product 9 injection mouldings.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spiritual defined scope of the utility model.
