Abstract
A kind of mould flow passage structure preventing deformation of products, comprise the sprue withstanding on product center, the end of described sprue be also provided with one perpendicular and with its UNICOM hold out against runner, the described two ends holding out against runner hold out against the inner side at product two ends, described holds out against some auxiliary flows runner being also provided with and holding out against runner UNICOM with this, and described auxiliary flow is distributed in the both sides of described sprue.The utility model supports by holding out against the two ends of runner to product, supported by the body of auxiliary flow to product simultaneously, the distortion of limits product, after product injection molded, again by the demoulding after the release of placement a period of time iso-stress, now product can not redeformation, improves the dimensional accuracy of product.
Description
Technical field
The utility model relates to a kind of mould flow passage structure.
Background technology
All there is certain injection molding deformation problem in all injecting products, when shaping longer product, product more greatly, longer, overall structure is thiner, and deflection is larger, and entangling its reason is that runner is only responsible for injection moulding, and does not play a supportive role to product.The deflection at this series products of normal condition two ends after injection moulding can be comparatively large, product actual with the use of central meeting because distortion size is to not going up.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing mold flow passage structure, the utility model provides a kind of mould flow passage structure preventing deformation of products.
The technical scheme in the invention for solving the technical problem is: a kind of mould flow passage structure preventing deformation of products, comprise the sprue withstanding on product center, the end of described sprue be also provided with one perpendicular and with its UNICOM hold out against runner, the described two ends holding out against runner hold out against the inner side at product two ends, described holds out against some auxiliary flows runner being also provided with and holding out against runner UNICOM with this, and described auxiliary flow is distributed in the both sides of described sprue.
The beneficial effects of the utility model are: support by holding out against the two ends of runner to product, supported by the body of auxiliary flow to product simultaneously, the distortion of limits product, after product injection molded, again by the demoulding after the release of placement a period of time iso-stress, now product can not redeformation, improves the dimensional accuracy of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, a kind of mould flow passage structure preventing deformation of products, comprise the sprue 2 withstanding on product 1 and hit exactly, the end of described sprue 2 be also provided with one perpendicular and with its UNICOM hold out against runner 3, the described two ends holding out against runner 3 hold out against the inner side at product 1 two ends, described holds out against the some auxiliary flows 4 runner 3 being also provided with and holding out against runner 3 UNICOM with this, and described auxiliary flow 4 is distributed in the both sides of described sprue 2.
Supported by the two ends holding out against runner 3 pairs of products, supported by the body of auxiliary flow 4 pairs of products simultaneously, the distortion of limits product 1, after product 1 injection molded, again by the demoulding after the release of placement a period of time iso-stress, now product can not redeformation, improves the dimensional accuracy of product.
