Abstract
The utility model relates to an anti-deformation structure for inserts in an injection mold. The anti-deformation structure for the inserts is installed in the injection mold; the injection mold comprises a movable template, a stationary template and base plates, the movable template and the stationary template can be clamped, and the base plates are installed on the movable template and the stationary template respectively; the middle parts of both the stationary template base plate and the movable template base plate are inward concave, and spaces are formed in the middle parts of the stationary template base plate and the movable template base plate; the spaces form a sealed cavity for injection after the movable template and the stationary template are clamped; a plurality of movable template inserts and stationary template inserts, which are matched with one another and in one-to-one correspondence, are installed coaxially and fixedly on the clamping surfaces of the spaces of the stationary template base plate and the movable template base plate, respectively; a bulge is installed on a squeezing contact surface of each movable template insert fixedly and is coaxial with the movable template insert; and a groove is formed in a squeezing contact surface of the stationary template insert coaxially corresponding to each movable template insert bulge, and is embedded and matched with the corresponding movable template insert bulge. According to the anti-deformation structure, when molds are clamped, the inserts are squeezed more tightly, so that the impact resistant strength of the inserts for feeding is improved effectively, and the problem of insert deformation caused by feeding impulsive force is solved.
Description
Technical field
The utility model belongs to mould applications, mold insert anti-deforming structure in especially a kind of injection mold.
Background technology
The existing mold insert that press fit normally is installed at the backing plate of dynamic and static template for the mould of injection moulding, around mold insert, be shaped with the space, behind dynamic and static mould matched moulds, form injection molding die cavity between space on the dynamic and static die-cushion plate and the backing plate inwall, be installed in the mutual crimping of mold insert on the dynamic and static die-cushion plate, finish thus the interior profile of injecting products.
And above-mentioned mould is in injection moulding process; owing to being subject to the restriction of the factors such as injecting products shape, specification, material, structure and processing method; mold insert lacks enough intensity usually; mold insert often can deform owing to the impulse force of charging near the injection moulding charging aperture time; affect outward appearance and the product serviceability of plastic parts moulding; not only produce defective, and easily caused the mould damage.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and mold insert anti-deforming structure in a kind of injection mold is provided, this structural strengthening the crushing strength of mold insert contact-making surface.
The technical solution adopted in the utility model is:
Mold insert anti-deforming structure in a kind of injection mold, this mold insert anti-deforming structure is installed in the injection mold, but this injection mold comprises the moving of matched moulds, quiet template and be installed in respectively moving, the backing plate of quiet template, quiet die-cushion plate and dynamic model backing plate middle part is indent and be shaped with the space all, this space forms injection molding near closed hollow ring behind dynamic model and quiet mould matched moulds, coaxial being fixed with cooperatively interacts and one to one a plurality of dynamic model mold inserts and quiet mould mold insert respectively on the matched moulds surface in quiet die-cushion plate and dynamic model backing plate space, extruding contact-making surface at each dynamic model mold insert all is fixed with a projection coaxial with the dynamic model mold insert, with each dynamic model mold insert all be shaped with the groove that cooperates with its corresponding dynamic model mold insert projection setting-in on the extruding contact-making surface of coaxial corresponding quiet mould mold insert.
And, described injection mold comprises quiet template, moving platen, matched moulds guide rod, on the matched moulds surface of quiet template quiet die-cushion plate is installed, these two ends, quiet die-cushion plate matched moulds surface are fixedly mounted with respectively a matched moulds guide rod, the corresponding side surface on quiet template matched moulds surface be equipped with one with the fixing locating ring of pedestal; On moving platen matched moulds surface one dynamic model backing plate is installed, be shaped with on the matched moulds surface of this dynamic model backing plate and two matched moulds guide rods of quiet mould guide hole one to one, quiet die-cushion plate and dynamic model backing plate middle part is indent and be shaped with the space all, this space forms injection molding near closed hollow ring behind dynamic model and quiet mould matched moulds, coaxial being fixed with cooperatively interacts and one to one a plurality of dynamic model mold inserts and quiet mould mold insert respectively on the matched moulds surface in quiet die-cushion plate and dynamic model backing plate space, and dynamic model mold insert and quiet mould mold insert form the interior profile of injecting products in die cavity after extruding cooperates mutually.
And, all be fixed with the mold insert holder respectively and between dynamic model backing plate and the quiet die-cushion plate at described each dynamic model mold insert, quiet mould mold insert.
Advantage and good effect that the utility model adopts are:
1, the utility model is by being fixedly mounted with projection and the groove of mutual coupling at dynamic and static die-cushion plate, push closelyr between the mold insert when making thus the mould matched moulds, Effective Raise the impact strength of mold insert for the injection moulding charging, thereby solved in injection moulding process because the problem of the mold insert distortion that the charging impulse force causes.
2, the utility model all is equipped with holder between mold insert and die backing plate, and the auxiliary compression strength that has improved mold insert has not only been saved production cost thus, and its clear in structure, and assembling is simple, and is applied widely, has good promotional value.
