Abstract
The utility model provides a mould for forming a multi-mesh structure, which comprises a front mould and a rear mould; the mould is provided with a front mould projection and a rear mould projection which are inserted into the meshes of the product, wherein the front mould projection is arranged on the front mould, and the rear mould projection is arranged on the rear mould. The front and the rear moulds are matched with each other to form meshes; a product parting line is arranged at the middle part of the meshes, so that the partial travel which is wrapped inside the product of the front and the rear moulds are greatly reduced, thus favoring the mould stripping. In addition, on the aspect of the stress, during the mould stripping, the front mould applies an upward stress on the product, and the rear mould applies a downward stress on the product, so that the stress on the opposite directions can be compensated with each other, and the final composite force is small, thereby being free from causing large stress on local part of the product, and being free from causing the scrape and the deformation of the product.
Description
Technical field
The utility model relates to the mould of injection mo(u)lding, relates in particular to a kind of how mesh-structured forming mould that is used for.
Background technology
The effect that plastics play more and more in modern manufacturing industry is important.Because plastics have characteristics such as light weight, low price, easy to process, specific strength height, so plastics use more and morely in the modern industry, more and more widely.Injection mo(u)lding is a kind of method commonly used in the plastic processing.Whether the quality of injection molding product quality rationally has very big relation with mould structure.Fig. 1 has shown and a kind ofly in the prior art has been used for how mesh-structured forming mould, comprise front mould 1 and back mould 2, front mould 1 has the front mould projection 11 that inserts product mesh (not shown), product parting line 4 is made in the front mould side of product 3, product parting line 4 is stayed the product back, be not easy to see, do not influence the outward appearance of product like this.But, the product by such mold injection aborning, in the time of the demoulding since the front mould projection 11 of front mould 1 to insert mesh deep, when product stripping, front mould 1 can give product a unidirectional upwards active force of (opposite with stripping direction).Mesh on product more for a long time, each mesh place all is subjected to the active force of same direction, will cause the mesh zone to be subjected to a bigger active force, will cause stress to concentrate for product 3.And for actual production process,, then may cause product 3 to stay in the front mould 1, even cause defectives such as product 3 scratches, distortion if the active force of 1 pair of product 3 of front mould is too big.
The utility model content
The technical problem that the utility model embodiment will solve is to provide a kind of how mesh-structured forming mould that is used for, and it is too dark to be intended to solve existing mold front mould insertion mesh, causes product easily to stay in the front mould, even causes the problem of product scratch, distortion.
The utility model embodiment realizes like this, a kind ofly be used for how mesh-structured forming mould, comprise front mould and back mould, described mould has and inserts front mould projection and the back mould projection that product produces mesh, the front mould projection is positioned on the front mould, and back mould projection is positioned on the mould of back.
Compared with prior art, technique scheme is inserted front mould projection and the back mould projection that product produces mesh because mould has, like this, by front mould and back mould applying formation mesh, the product parting line is positioned at roughly middle part of mesh, the partial journey that makes front mould, back mould be enclosed in the product reduces greatly, and this more helps depanning.In addition, from stressed angle, in the process of die sinking, front mould can give product the unidirectional upwards active force of (opposite with stripping direction), and then mould can give product the unidirectional active force of (identical with stripping direction) downwards simultaneously.Like this, both direction opposite effect power will be cancelled out each other, and final is smaller with joint efforts, also can not cause the excessive problem of local stress to product, also can therefore not cause the problem of product scratch, distortion.
Description of drawings
Fig. 1 is that prior art provides a kind ofly is used for how mesh-structured mould;
Fig. 2 be the utility model one preferred embodiment provide be used for how mesh-structured mould.
Fig. 3 is the I place enlarged drawing of Fig. 2.
The specific embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 2 and Fig. 3 have shown a preferred embodiment of the present utility model, are used for how mesh-structured forming mould, comprise front mould 5 and back mould 6, and front mould 5 has front mould projection 51, and back mould has back mould projection 61.Front mould 5 is fitted mutually with the opposing end faces of back mould 6, can form mesh-structured (not shown) after the formed product, product parting line 4 is changed roughly middle part of mesh by traditional back mould somatotype, the partial journey that makes front mould 5, back mould 6 be enclosed in 3 li of products reduces greatly, this more helps depanning, and this is particularly important to the deep product of some mesh.In addition, from stressed angle, in the process of die sinking, front mould 5 can give product the unidirectional upwards active force of (opposite with stripping direction), and then mould 6 can give product the unidirectional active force of (identical with stripping direction) downwards simultaneously.Like this, both direction opposite effect power will be cancelled out each other, and final is smaller with joint efforts, therefore can not cause the excessive problem of local stress to product, also just can therefore not cause the problem of product scratch, distortion.
The degree of depth that mould projection 61 inserts after the depth ratio of above-mentioned front mould projection 51 insertion products is little.Like this, because the insertion depth of back mould 6 is darker than front mould 5, the active force of 6 pairs of products of back mould, so more helps product and stays in the mould 6 of back so its direction of making a concerted effort is pointed to back mould 6 greater than front mould 5 like this.Specifically, in the present embodiment, the mesh degree of depth is T, and the degree of depth of front mould projection 51 is T1, and T1 is T/3.The degree of depth of back mould projection 61 is T2, and T2 is 2T/3.
Among the utility model embodiment shown in the drawings, joint place part edge at least forms an outward extending step.Front mould projection 51 is fitted mutually with back mould projection 61 opposing end faces, and front mould projection 51 is littler than back mould projection 51, thus make its joint place at least part edge formation one amount of stretching out be the step of L, L is 0.1～0.3mm, preferably 0.2mm.The mesh that the mesh that this step can make front mould partly form partly forms less than the back mould.Can reduce required precision like this, allow the front mould 5 of mould and back mould 6 that certain deviation is arranged mould.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
