Abstract

The utility model discloses an injection mould with a film positioning mechanism. The injection mould with the film positioning mechanism comprises a male mould, a female mould and a female mould base, wherein the lower portion of the female mould is fixedly connected with the female mould base, and the upper portion of the female mould is provided with the male mould. The injection mould with the film positioning mechanism is characterized by further comprising a mould insert, the female mould is provided with an opening, the mould insert is arranged inside the opening, the bottom of the mould insert is connected with the top of the female mould base through a spring, and when the mould insert is bounced by the spring, the top of the mould insert can extend out of the top of the female mould. The injection mould with the film positioning mechanism resolves the problems that in the prior art, when a film is arranged into an injection mould cavity and the film and resin are molded in an injection mode, the positioning of the film is difficult, great difficulty is brought to subsequent injection machining, the position of the film in an injection product deviates easily, and product quality is greatly affected. The injection mould with the film positioning mechanism can position the film quickly and conveniently and guarantees the film in the process of injection is in a correct machining position.

Description

A kind of injection mold that has the film detent mechanism

Technical field

The utility model belongs to the injection molding technology field, particularly relates to a kind of injection mold that has the film detent mechanism.

Background technology

MF (In mold film) plastic rubber shaping technology is promptly: what will print pattern has body or asomatous film to put into to penetrate model cavity and is integral with resin injection molding.Film mainly is structure location such as pattern tool die cavity or boss; If but the profile of film can't play positioning action less than the height of mold cavity or boss; Want so to realize that the film location is just very difficult; Bring bigger difficulty for so follow-up injection moulding processing, film position squints easily in the injecting products, has influenced the quality of product greatly.

The utility model content

Put into and penetrate model cavity and resin injection molding in order to solve in the prior art film; The film location is difficulty comparatively; Bring bigger difficulty for follow-up injection moulding processing, film position squints easily in the injecting products, has influenced the problem of product quality greatly; The utility model provide a kind of can quick and convenient location film, film is in the injection mold that has the film detent mechanism of correct machining position when guaranteeing injection moulding.

In order to address the above problem, the technical scheme that the utility model is taked is:

A kind of injection mold that has the film detent mechanism comprises male model, master mold and female die seat, below master mold, is fixedly connected with female die seat; Above master mold, be provided with male model; It is characterized in that: also include son, master mold is provided with opening, saidly goes into son and is installed in the opening; The said bottom of going into son is connected with the female die seat top through spring, saidly goes into subly to go into sub-top when being upspring by spring and can stretch out the master mold top.

Aforesaid a kind of injection mold that has the film detent mechanism; It is characterized in that: said opening is the stairstepping opening; Saidly go into son and go into son for the T type, the T type is gone into son and is installed in the stairstepping opening, and the countersunk head that said T type is gone into sub-two bottom sides extend into respectively in the step of stairstepping opening both sides.

Aforesaid a kind of injection mold that has the film detent mechanism is characterized in that: the bottom that said T type is gone into son is connected with the female die seat top through two springs.

The beneficial effect of the utility model is: the utility model is made movable spring with the boss of mould and is gone into son, promptly is lowered to bullet in the situation of die sinking and plays (height can design as required), at this moment utilizes the holes on the film just can easily film be located; Because it is mobilizable going into son; When matched moulds, will go into son and push back original position by the die face of opposite side; The structure that guarantees the mould matched moulds is unaffected, and the utility model injection mold can be located film fast, has guaranteed that film is positioned at the right processing position when follow-up injection moulding; Improved machining accuracy, product quality has obtained significantly promoting.

Description of drawings

Fig. 1 is the injection mold die opening state sketch map that the utility model has the film detent mechanism.

Fig. 2 is the injection mold matched moulds view that the utility model has the film detent mechanism.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further description.

Shown in Fig. 1-2; A kind of injection mold that has the film detent mechanism, comprise male model 1, master mold 2, female die seat 3 and T type go into the son 4, below master mold 2, be fixedly connected with female die seat 3; Above master mold 2, be provided with male model 1; Master mold 2 is provided with stairstepping opening 5, and the T type is gone into son 4 and is installed in the stairstepping opening 5, and the bottom that the T type is gone into son 4 is connected with female die seat 3 tops through two springs 6; The countersunk head 7 that the T type is gone into sub 4 two bottom sides extend into respectively in the step 8 of stairstepping opening 5 both sides, the T type go into son 4 when being upspring by spring the T type go into sub 4 tops and can stretch out master mold 2 tops.

After the utility model injection mold male model 1, master mold 2 were opened, the T type was gone into son 4 and is leaned on spring 6 to upspring, and it designs highly according to actual needs; Go into after son 4 upsprings when the T type, the T type is gone into sub 4 front end ledges can locate film fully, and when male model 1, master mold 2 were closed then, in closing course, the T type was gone into son 4 and leaned on the die faces of male model 1 to push back the home position, guarantees that product structure is unaffected.The countersunk head 7 that the utility model T type is gone into sub 4 two bottom sides extend into respectively in the step 8 of stairstepping opening 5 both sides; Go into the Shi Buhui that upsprings of son 4 and thoroughly eject to guarantee the T type; It is spacing by the countersunk head of bottom that the T type is gone into son 4 like this, guaranteed that injection mold has long service life.

More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
