Abstract
The invention discloses a strain-preventing injection mould. The strain-preventing injection mould comprises a cavity insert and a core insert, an inclined guide pillar, a sliding block and a stop dog, wherein a cavity of a product to be processed is formed between the cavity insert and the core insert; the inclined guide pillar and the sliding block are positioned on one side of the cavity; the stop dog is arranged in the cavity insert, and the lower end of the stop dog is mutually contacted with the outer side surface of the product to be processed. According to the strain-preventing injection mould provided by the invention, the product has a deep rib position, the stop dog is arranged to effectively block the product, so that the product is prevented from straining; the strain-preventing injection mould provided by the invention has the characteristics that the installation is simple, the process is simple, the mould opening efficiency is high, and the production efficiency is improved. The structure of the strain-preventing injection mould provided by the invention is arranged in the inserts, and thus, the structure is suitable for a mould at which a thimble can not be arranged in a small sliding block.
Description
Technical field
The present invention relates to a kind of anti-injection mold of pulling.
Background technology
In process of production, when product side has very dark muscle position, slide block is wrapped in very dark muscle position to mould, in die sinking process, because product die sinking is very fast, under the effect of moment pulling force, is easy to product to pull, and drawing crack is opened even.Thereby whole product injection moulding is exactly out scrap, and waste of manpower, wastes financial resources, increase cost of material, for fear of product is pulled, injection moulding machine mould open process control chronic, what cause that whole injection cycle becomes is very long.
Summary of the invention
The present invention is intended at least solve one of technical problem existing in prior art.
For addressing the above problem, the present invention proposes a kind ofly anti-to pull injection mold, comprising: mother module core and male die core, form the die cavity of processed product between described mother module core and male die core; Angle Pin and slide block, described Angle Pin and slide block are positioned at described die cavity one side; Block, described block is located in described mother module core, and lower end contacts with the lateral surface of processed product.
Injection mold according to the present invention, when product has very dark muscle position, arranges a block, can when die sinking, effectively block product, prevents that product from pulling.The feature that injection mold of the present invention has is easy for installation, processing simple, die sinking efficiency is high, can enhance productivity.Structure of the present invention, owing to being located at die inside, is therefore applicable to the mould that small slide block cannot be placed thimble.
In addition, according to injection mold of the present invention, also there is following additional technical feature:
Preferably, the upper end of described block is not higher than the upper surface of mother module core.
Preferably, described block is slidably located in mother module core, and described block upper end is provided with hanging platform, and hanging platform is positioned at the hanging groove that is located at mother module core, and the height of described hanging groove is greater than the height of hanging platform.
Preferably, the height of described block is less than the height 0.01-0.05mm of mother module core.
Additional aspect of the present invention and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present invention and advantage accompanying drawing below combination obviously and is easily understood becoming the description of embodiment, wherein:
Fig. 1 is the structural representation of a kind of injection mold of the present invention.
description of reference numerals:
Mother module core 1; Male die core 2; Angle Pin 3; Slide block 4; Block 5; Product 6.
The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Below with reference to Fig. 1, describe according to a kind of injection mold of the embodiment of the present invention.As shown in Figure 1, injection mold of the present invention comprises mother module core 1, male die core 2, Angle Pin 3, slide block 4, block 5 and product 6.
Between described mother module core 1 and male die core 2, form the die cavity of processed product 6; Described Angle Pin 3 and slide block 4 are positioned at described die cavity one side; Described block 5 is located in described mother module core 1, and lower end is for contacting with the lateral surface of processed product 6.
Injection mold according to the present invention, when product 6 has very dark muscle position, arranges a block 5, can when die sinking, effectively block product 6, prevents that product 6 from pulling.The feature that injection mold of the present invention has is easy for installation, processing simple, die sinking efficiency is high, can enhance productivity.Structure of the present invention, owing to being located at die inside, is therefore applicable to the mould that small slide block 4 cannot be placed thimble.
As a preferred exemplary of the present invention, described block 5 is slidably located in mother module core 1, and described block 5 upper ends are provided with hanging platform, and hanging platform is positioned at the hanging groove that is located at mother module core 1, and the height of described hanging groove is greater than the height of hanging platform.Like this, in a bit of time after die sinking, block 5 can fall a segment distance, and its lower end leans against on the upper surface of slide block 4 always, can effectively block better product 6, prevents that product 6 from pulling.
The upper end of described block 5 is not higher than the upper surface of mother module core 1.The height of described block 5 is less than the height of mother module core 1, and tolerance is between-0.01-0.05mm.In the time of can preventing matched moulds thus, block 5 clashes into slide block 4.Material is different, and tolerance value is also different.
In the description of this description, the description of reference term " embodiment ", " example " or " some examples " etc. means to be contained at least one embodiment of the present invention or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
