The male die is equipped with at least one feed channel; the inclined pin is arranged in the male die and the inclined pin can form a molding space with the male and female dies; the inclined pin is also equipped with a concave structure with a spruce connected with the feed channel; the plastic materials is fed into the molding space through the feed channel to form a plastic part.
Description
Technical field
The utility model relates to a kind of plastics injection mould, and particularly a kind of being applicable to has the plastics injection mould that taper pin advances plastic structure.
Background technology
Injection molding is a kind of mode of production of industrial a large amount of uses at present, its process parameter adjustment is very difficult, injection molding has considerable process parameter to be needed to adjust, for example plastics temperature, injection pressure, mold temperature, injection moulding speed etc., when process conditions is adjusted when incorrect, will produce number of drawbacks on plastic injection-moulded finished product, for example plastics burn trace, number of drawbacks such as lines, indenture flow.Particularly when the finished product size is big, enter glue position regular meeting and produce because temperature is too high and burn trace, or because the plastics temperature is not enough the mobile lines of generation.Particularly when injection molding is applied to the in-mold transfer printing processing procedure, regular meeting because plastic warm to spend height or pressure excessive and the destruction of causing transfer film makes that the decorative pattern on the transfer film can't be transferred to finished surface smoothly.
In view of the existing shortcoming of above-mentioned plastics injection mould, be necessary to propose a kind of plastics injection mould, its temperature of entering the glue position can be not too high, cause finished surface defective or because plastic warm to spend height or pressure excessive and cause the destruction or the flaw of transfer film, make that the decorative pattern on the transfer film can't be transferred to finished surface smoothly.
Summary of the invention
The purpose of this utility model is for proposing a kind of plastics injection mould, its temperature of entering the glue position can be not too high, and cause the defective of finished surface or the destruction of causing transfer film because plastic warm spends height, make that the decorative pattern on the transfer film can't be transferred to finished surface smoothly.
For reaching above-mentioned purpose, the utility model provides a kind of plastics injection mould that taper pin advances plastic structure that has, and it comprises: a master mold; One male model, this male model has at least one running channel; An and taper pin, this taper pin is arranged at this male model, this taper pin, this male model and this master mold can form a molding space jointly, and this taper pin has a sunk structure, this sunk structure has a cast gate and is connected with this running channel, and a plastic material is fills up to this molding space by this running channel and forms a plastic components.
Useful technique effect of the present utility model: have a plastics injection mould that taper pin advances plastic structure by of the present utility model, its temperature of entering the glue position can be not too high, can not cause finished surface defective or because plastic warm to spend height or pressure excessive and the destruction of causing transfer film makes that the decorative pattern on the transfer film can't be transferred to finished surface smoothly.

The specific embodiment
Fig. 1 shows the plastics injection mould 200 that taper pin advances plastic structure that has of the utility model one preferred embodiment, and this plastics injection mould 200 comprises: a master mold 210, a male model 220 and a taper pin 230.This male model 220 has at least one running channel 221 and at least one knock pin 222; This taper pin 230 is arranged at this male model 220, and this taper pin 230, this male model 220 can form a molding space jointly with this master mold 210, this taper pin 230 has a sunk structure 231 in addition, this sunk structure 231 has a cast gate 2311 and is connected with running channel 231, wherein, one plastic material is fills up to this molding space by this sunk structure 231 and forms a plastic components, and this plastic components forms one by this sunk structure 231 and advances the glue buffer structure.
When this plastic components cooling, male model 220 separates with master mold 210, this taper pin 230 moving of mould 230 and on business simultaneously by separating with this plastic components the side, and then by knock pin 222, this plastic components is ejected, to advance the glue buffer structure at last again by removing on the plastic components, wherein when carrying out the ejecting of this plastic components, but knock pin 222 ejections this advance the glue buffer structure.
Fig. 2 shows the schematic diagram of the taper pin 230 among Fig. 1.This taper pin 230 has an applying plane 232, this applying plane 232 is in order to fit with male model 220, when sizing material entered sunk structure 231 with male model 220 formed spaces by cast gate 2311, the gas that mould and sizing material are carried secretly can be discharged by the slit between applying plane 232 and the male model 220.Wherein, sunk structure 231 comprises a buffer area 2312 and and enters glue zone 2313, buffer area 2312 be one with the vertically extending strip of injecting glue direction space, entering 2313 in glue zone is the diminishing space of a sectional area, when sizing material is injected by cast gate 2311, can in sunk structure 231, relax temperature and pressure, and then enter 2313 stable master molds 210 and the male model 220 formed spaces injected, glue zone by sectional area is diminishing.
What Fig. 3 showed plastic components among Fig. 1 advances the glue buffer structure.This advances glue buffer structure 250 and comprises a buffer structure 251 and and advance plastic structure 252, buffer structure 251 has a strip external form, advance plastic structure 252 and have the diminishing external form of a sectional area, because advancing plastic structure 252 has the diminishing external form of a sectional area, remove plastic components advance the glue buffer structure time, the position of advancing plastic structure 252 can fracture easily.
Has a plastics injection mould that taper pin advances plastic structure by of the present utility model, its temperature of entering the glue position can be not too high, the defective that causes finished surface can not spent the excessive and destruction of causing the transfer film of in-mold transfer printing processing procedure of height or pressure because of plastic warm yet, and makes the decorative pattern on the transfer film can't be transferred to finished surface smoothly.
Above-mentioned embodiment of the present utility model only is explanation technological thought of the present utility model and characteristics, its purpose makes those skilled in the art can understand content of the present utility model and is implementing according to this, when can not with qualification claim of the present utility model, be that all other do not break away from the various changes of the equivalence that spirit that the utility model discloses finishes or modify and all be encompassed in the disclosed scope of the utility model, all should be included in the scope of claims.
