Abstract
The utility model discloses a kind of die positioning structure and its injection molds, the injection mold successively includes cover half fixed plate, hot runner manifold, solid plate, moving template, support block and dynamic mould fixing plate from top to bottom, the type core of the injection mold is arranged on the moving template, the type core is equipped with several positioning and plays needle, the type core of the mold is equipped with several positioning and plays needle, when the type in-core injects a large amount of thermoplastic materials, the positioning bullet needle compression after-contraction.The utility model plays the effect of needle by positioning, thermoplastic materials is distributed more uniform, so that product surface will not generate groove, surface smoothness is higher, and product surface is more beautiful.
Description
Technical field
The utility model relates to a kind of die positioning structure and its injection molds.
Background technique
Embedding membrane type is molded decoration technology, refers to that the film a plastics sucking moulding is put into injection molding in injection mold.
But the film of plastics sucking moulding is still very fragile, the location structure of existing injection mold is bad, so that film holds in injection molding
The active force influence generated when vulnerable to thermoplastic materials flowing leads to displacement, deformation, therefore rejection rate is high.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing injection mold, the utility model provides a kind of die positioning structure and its injection molding
Mold.
The technical scheme in the invention for solving the technical problem is: a kind of die positioning structure, on the type core of the mold
Needle is played equipped with several positioning, when the type in-core injects a large amount of thermoplastic materials, the positioning bullet needle compression after-contraction.
A kind of injection mold using above-mentioned die positioning structure, the injection mold are successively fixed including cover half from top to bottom
The moving template is arranged in the type core of plate, hot runner manifold, solid plate, moving template, support block and dynamic mould fixing plate, the injection mold
On, the type core is equipped with several positioning and plays needle.
Further, the solid plate is equipped with wedge block, opens up fluted, described wedge block on the moving template
It is caught in the groove.
Further, the wedge block is equipped with inclined guide pillar, offers in the groove compatible with the inclined guide pillar
Inclined hole.
Further, pressure block is additionally provided on the solid plate.
Further, locating ring is equipped on the cover half fixed plate and dynamic mould fixing plate.
The utility model has the beneficial effects that: playing the effect of needle by positioning, thermoplastic materials is distributed more
Even, so that product surface will not generate groove, surface smoothness is higher, and product surface is more beautiful.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the solid plate of the utility model.
Fig. 3 is the structural schematic diagram of the moving template of the utility model.
Fig. 4 is the partial sectional view of the utility model.
Fig. 5 is the enlarged drawing of part A in Fig. 4.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1~Fig. 5, a kind of die positioning structure, the type core 1 of the mold is equipped with several positioning and plays needle 2, when described
When injecting a large amount of thermoplastic materials in type core 1, the 2 compression after-contraction of positioning bullet needle.
Preferably, the positioning bullet needle 2 includes playing needle main body 15, briquetting 16 and setting in briquetting and playing needle main body
Between spring 17 elastic force that the positioning plays needle is controlled within 1KG according to the characteristic of thermoplastic materials.
A kind of injection mold using above-mentioned die positioning structure, the injection mold are successively fixed including cover half from top to bottom
The type core 1 of plate 3, hot runner manifold 4, solid plate 5, moving template 6, support block 7 and dynamic mould fixing plate 8, the injection mold is arranged described
Moving template 6 on, the type core 1 be equipped with several positioning bullet needle 2.
In the present embodiment, the solid plate 5 is equipped with wedge block 9, opens up fluted 10 on the moving template 6, institute
The wedge block 9 stated is caught in the groove 10.The wedge block 9 is equipped with inclined guide pillar 11, offers in the groove 10
Inclined hole 12 compatible with the inclined guide pillar 11.After the wedge block 9 is caught in groove 10, the inclined guide pillar 11
In the insertion inclined hole 12.This kind of structure can play guiding and positioning action in vertical, transverse direction, so that dynamic model and cover half
Cooperate precision higher, and then reduces the defect rate of product.
In the present embodiment, pressure block 13 is additionally provided on the solid plate 5.The moving template 6 and solid plate 5 of mold are opening and closing
When generate biggish pressure, by the effect of the pressure block 13, so that the mold is able to bear bigger pressure, improve product
Qualification rate.
In the present embodiment, it is equipped with locating ring 14 on the cover half fixed plate 3 and dynamic mould fixing plate 8, the locating ring 14
Convenient for the positioning and dismounting of injection mold.
When the utility model is used, the film of plastics sucking moulding is put into type core 1, and needle 2 is played by positioning and is positioned, this
Shi Dingwei bullet needle 2 is in normal condition；Then mold and inject thermoplastic materials, when thermoplastic materials reaches it is a certain amount of after, positioning play needle 2 by
Compressive strain enables thermoplastic materials to be distributed more uniform, so that product surface will not generate groove 10, surface smoothness is more
Height, product surface are more beautiful.
