Abstract
The invention discloses an injection mold with an auxiliary boss. The injection mold comprises a male mold and a female mold, wherein a rubber inlet runner is arranged on the female mold. The injection mold is characterized by also comprising a boss, wherein the boss is arranged at the outer side of a cavity of the female mold; a groove communicated with the cavity of the male mold is arranged at the outer side of the cavity of the male mold; a pouring runner communicated and connected with the rubber inlet runner is arranged in the boss, and the pouring runner is thinner and thinner towards the pouring runner pipeline at a rubber outlet; and the rubber outlet of the boss pouring runner is over against the groove of the male mold. By adopting the injection mold, the problems in the prior art that greater loss is brought to enterprises due to a greatly improved product reject ratio because the quality of products is influenced by mold stamping phenomena easily caused by that rubber enters from the side surface for plastic products with films are solved. According to the injection mold with the auxiliary boss, plastic rubber can flow to the back side of a film during rubber inlet to guarantee that the plastic rubber cannot stamp over the film.
Description
Technical field
The invention belongs to the injection molding technology field, particularly relate to a kind of injection mold that is provided with auxiliary boss.
Background technology
As shown in Figure 1, IMF (In mold film) plastic rubber shaping technology promptly: what will print pattern has body or asomatous film 3 to put into to penetrate model cavity and is integral with resin injection molding, and promptly product simultaneously is a plastic cement 2, and another simultaneously is a film 3.Be appearance like the product two sides, can not design on any one side, can only advance glue from the side of product so enter solation road 1.As shown in Figure 2, but thinner like the fruit product wall thickness, the side is advanced glue and can be caused towards the film phenomenon, when promptly plastic cement 2 flows dashes film 3 and rebuilds or renovate into badly, has influenced the quality of product like this, and the product fraction defective improves greatly, has brought bigger loss to enterprise.
Summary of the invention
Advance glue from the side in order to solve the plastic cement products that has film in the prior art; Cause easily towards the film phenomenon; Influenced the quality of product, the product fraction defective improves greatly, has brought the problem of greater loss to enterprise; The invention provides a kind of when advancing glue plastic cement can the very first time flow to the film reverse side, guarantee that plastic cement can not dash the injection mold that is provided with auxiliary boss that turns over film.
In order to address the above problem, the technical scheme that the present invention taked is:
A kind of injection mold that is provided with auxiliary boss; Comprise male model and master mold, master mold is provided with into solation road, it is characterized in that: also comprise boss; Arranged outside at the master mold die cavity has boss; In male model die cavity arranged outside the groove that connects with the male model die cavity is arranged, in boss, be provided with entering the solation road and connect the running channel that is connected, the gum outlet of said boss running channel is right against the male model groove.
Aforesaid a kind of injection mold that is provided with auxiliary boss, it is characterized in that: said running channel is thin more to gum outlet running channel pipeline more.
Aforesaid a kind of injection mold that is provided with auxiliary boss, it is characterized in that: said male model groove is connected through arcwall face with the male model die cavity.
The invention has the beneficial effects as follows: injection mold of the present invention advances glue from the front of film extension site; Be filled to the reverse side of film the plastic cement very first time through the gum outlet of boss; Overall flow is steady; Guarantee that plastic cement can not be flushed to film, the position that last plastic cement finished product excises extension again obtains required processing article, and product quality has obtained strong assurance.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Shown in Fig. 3-6, a kind of injection mold that is provided with auxiliary boss comprises male model 4, master mold 5 and boss 6; Arranged outside at master mold 5 die cavitys has boss 6; In male model 4 die cavitys 7 arranged outside the groove 8 that connects with male model 4 die cavitys 7 is arranged, master mold 5 is provided with into solation road 9, in boss 6, is provided with running channel 10; Running channel 10 connects and is connected with entering solation road 9, and the gum outlet 12 of boss 6 running channels 10 is right against male model 4 grooves 8.
Running channel 10 is more to gum outlet 12, and the pipeline of running channel 10 is thin more, is convenient to gum outlet 12 injections like this.Male model 4 grooves 8 are connected through arcwall face 11 with male model 4 die cavitys 7 simultaneously, and are more steady when plastic cement is from groove 8 entering die cavitys 7 like this, and can not dash and turn over film 3, the stability in the time of having guaranteed the injection moulding circulation,
The present invention extends film 3; Be designed with locating hole on the extension, when male model 4 is opened with master mold 5, film 3 be positioned on the master mold; Through locating hole on the extension and cooperating of boss 6 film 3 being fixed on the master mold 5, to guarantee behind the location that the height of boss 6 is higher than the height of film 3.Behind male model 4 and master mold 5 matched moulds; Master mold 5 enter solation road 9 to mold injection plastic cement 2; Gum outlet 12 through boss 6 advances glue to the groove 8 of male model 4, and plastic cement 2 flow in the die cavity of male model 4 die cavitys 7 and master mold 5 die cavitys composition through groove 8 then, and plastic cement 2 flow to film 3 reverse side with regard to the very first time like this; Guaranteed that plastic cement 2 can be towards turning over film 3; The position that last plastic cement finished product excises extension again obtains required processing article, but advances glue through above-mentioned injecting glue mode quick and stable, has guaranteed the quality of product.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
