Abstract
The utility model relates to an injection mould with a delay core pulling mechanism, which comprises a sprue bush plate, a sprue bush partition plate, a fixed template and a movable template, wherein a fixed mould core and a movable mould core are respectively inserted into the fixed template and the movable template; a pressure block is arranged on the fixed mould core; a side core pulling block is arranged on the movable mould core; the pressure block and the side core pulling block are in close fit; a spring in a pre-compression state is arranged between the pressure block and the side core pulling block; and an oil cylinder is arranged at the tail part of the side core pulling block. According to the injection mould provided by the utility model, by adopting the simple pressure block and the effect of the spring, in a mould splitting process, a pouring system can be separated firstly; in a process of separating the fixed template from the movable template, the side core pulling block can be kept in a static state relative to the movable mould core due to the acting force of the compression spring and through the transverse limitation of the inclined guide pillar; and after the fixed template and the movable template are completely separated, the side core pulling action is performed through the oil cylinder. The injection mould provided by the utility model has the advantages of simple structure and great practicability.
Description
Technical field
The utility model relates to the injection mold technical field, especially a kind of injection mold with delay core pulling.
Background technology
In known technical field, a kind of processing method of using when injection mo(u)lding is some complex-shaped parts of batch production, specifically the finger material that melts that will be heated is injected die cavity by high pressure, after cooling curing, obtain formed products, and injection mold is a kind of instrument of producing plasthetics, is also the instrument of giving plasthetics complete structure and accurate dimension.When facing actual product, sometimes due to the complicated variety of the running gate system of mould, and product has side core-pulling mechanism simultaneously, in the process of mold releasability, if in running gate system and separation of products, product carries out again the words of the process of side core-pulling, be easy to cause product to pull, its structure is caused bad impact, thus need first running gate system and separation of products, and then carry out side core-pulling.
The utility model content
The technical problems to be solved in the utility model is: a kind of injection mold with delay core pulling is provided.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of injection mold with delay core pulling, comprise the cast gate cage plate, the sprue bush dividing plate, solid plate and moving platen, inlay respectively on described solid plate and moving platen fixed mold core and mavable module core are installed, be provided with briquetting on described fixed mold core, be provided with the side core-pulling piece on described mavable module core, fit tightly between described briquetting and side core-pulling piece, and be provided with the spring that is its pre-compressed state between described briquetting and side core-pulling piece, be provided with Angle Pin on described side core-pulling piece, and described Angle Pin is inserted in solid plate, afterbody at described side core-pulling piece is provided with oil cylinder.
Further, in order to facilitate mounting spring, the utility model is provided with set bolt between described briquetting and side core-pulling piece, and the described spring housing that is its pre-compressed state is located on described set bolt.
Further, for stability and the anti-wear performance that improves relative motion between side core-pulling piece and moving platen, the utility model is provided with wearing plate between described side core-pulling piece and moving platen.
The beneficial effects of the utility model are: the utility model is by adopting the effect of simple briquetting and spring, divide in the process of mould at mould, can first carry out the separation of running gate system, in solid plate and process that moving platen separates, the side core-pulling piece is due to the active force of Compress Spring, and the horizontal restriction by Angle Pin, can make the side core-pulling piece keep relative static state with mavable module core, separate with moving platen at solid plate complete after, carry out the action of side core-pulling by oil cylinder, this programme is simple in structure, has practicality.
