Abstract
The utility model discloses a high-gloss injection mold, wherein an injection molding cavity is formed in a main body of the injection mold; a flow passage is formed on the main body of the injection mold; the flow passage is communicated with the injection molding cavity through an injection molding opening; the injection mold further comprises a cutter and a push device used for pushing the cutter; and the a blade of the cutter faces to the injection molding opening. The high-gloss injection mold eliminates the original secondary clamping procedure, and has the advantages of high production efficiency and good appearance quality of products.
Description
Technical field
The utility model relates to a kind of high-gloss injection mold.
Background technology
Development along with Tool and Die Technology, and transparent material, the application more and more widely of high luminescent material, people also propose more and more higher requirement to injection moulding, it is exactly highlighted that the product of employing transparent material and the injection moulding of high luminescent material institute has a common characteristic, and adopt traditional injection mold, after the product injection moulding is finished, product is taken out by the workman, remove the cast gate material of staying product surface then, there is following shortcoming in this injection mold:
1, need increase frock in addition, complicated clamping carries out secondary operations, influences production efficiency;
2, clamp in the process at secondary, product is caused damage easily, defectives such as scuffing;
3, for high light series products, by workman's pickup, stay vestiges such as fingerprint easily at product surface, influence the presentation quality of product;
4, adopt the processing of secondary clamping, be unfavorable for the automated production of product.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of high-gloss injection mold is provided, and the utility model can save original secondary and clamp operation, and the presentation quality of production efficiency height, product is good.
Its technical scheme is as follows:
A kind of high-gloss injection mold is provided with injection molding cavity in die main body, be provided with runner on die main body, and runner communicates with injection molding cavity by injection hole; The thrust unit that this mould also includes cutting knife and cutting knife is promoted, the edge of a knife of cutting knife is towards injection hole.
When injection moulding, liquid transparent material or high luminescent material can enter in the injection molding cavity by runner, injection hole, and after injection moulding was finished, can retain between injection hole and runner had the cast gate material, start thrust unit this moment, cutting knife moves under the effect of thrust unit and the cast gate material is excised.The utility model has saved original secondary and has clamped operation, and efficient is higher, good product quality.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Be provided with chute on described die main body, described cutting knife can slide in this chute.
Described thrust unit comprises piston/cylinder unit, slide block and back-moving spring, and slide block can slide with respect to described die main body, and slide block is connected with piston/cylinder unit, is provided with the inclined-plane that matches on slide block and described cutting knife, and cutting knife is connected with back-moving spring.Piston/cylinder unit moves under the effect of hydraulic oil or high pressure gas, will drive slide block and move, owing between slide block and the cutting knife inclined-plane that matches is arranged, when slide block moved, cutting knife also can move and the cast gate material is cut off; The piston/cylinder travelling backwards, cutting knife resets under the effect of back-moving spring.
In sum, the utility model has the advantages that: product injection moulding efficient is higher, and quality is good.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1 and Figure 2, a kind of high-gloss injection mold is provided with injection molding cavity 2 in die main body 1, be provided with runner 4 on die main body 1, and runner 4 communicates with injection molding cavity 2 by injection hole 3; The thrust unit that this mould also includes cutting knife 7 and cutting knife 7 is promoted, the edge of a knife of cutting knife 7 is towards injection hole 3.
Wherein, be provided with chute 9 on described die main body 1, described cutting knife 7 can slide in this chute 9; Described thrust unit comprises piston/cylinder unit 5, slide block 6 and back-moving spring 10, slide block 6 can slide with respect to described die main body 1, and slide block 6 is connected with piston/cylinder unit 5, is provided with the inclined-plane 8 that matches on slide block 6 and described cutting knife 7, and cutting knife 7 is connected with back-moving spring 10.
When injection moulding, liquid transparent material or high luminescent material can enter in the injection molding cavity 2 by runner 4, injection hole 3, after injection moulding is finished, can retain between injection hole 3 and runner 4 has the cast gate material, and start thrust unit this moment, and promptly piston/cylinder unit 5 moves under the effect of hydraulic oil or high pressure gas, to drive slide block 6 moves, because between slide block 6 and the cutting knife 7 inclined-plane 8 that matches is arranged, when slide block 6 moved, cutting knife 7 also can move and the cast gate material is cut off; The piston/cylinder travelling backwards, cutting knife 7 resets under the effect of back-moving spring 10, and present embodiment has saved original secondary and has clamped operation, and efficient is higher, good product quality.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
