Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an injection mold who is used for injection mold's adjustable interceptor and has this interceptor.
[ background of the invention ]
In the production practice of injection molds, due to various limitations (such as cost, and strict standard of color difference of different assemblies), there are many cases where several products with different sizes and shapes need to be simultaneously injection-molded on one set of molds, which leads to the problem that the filling of each mold cavity is difficult to balance.
The amount of glue required for each cavity is different due to the different shapes and volumes of the individual products. The synchronous glue feeding of each cavity with different sizes needs to be controlled, and the pressure of the mold cavity is basically equivalent to meet the requirement of product quality. In order to solve the problem, in continuous discussion and experiments, the amount of molten glue injected in unit time is known to directly influence the pressure of a formed cavity, that is, the size of a glue opening in a certain proportion is designed for products with different sizes and volumes during mold design, and the amount of molten glue injected in unit time can be properly adjusted through different sizes of the glue opening, so that the pressure of the cavity of each product with different sizes is balanced.
However, in practice we have found that it is not sufficient to adjust the die cavity pressure balance solely by sizing the volume to the size of the gate. Therefore, we have developed an adjustable injection molding filling shutoff device through experiments to better balance the cavity pressure of products of different sizes.

An object of the utility model is to overcome prior art's weak point, provide a simple structure, it is with low costs, the too big problem of shearing force when having solved the plastic and filling, can prevent cold glue, cull pocket from staying, improve the injection line problem of some outward appearance A level face, simple structure, the cheap interceptor for injection mold of erection side.
Another object of the utility model is to provide an injection mold who has solved the too big problem of shearing force when the plastic fills, can prevent that cold glue, incomplete glue pocket from staying, improves the injection line problem of some outward appearance A level face.
The purpose of the utility model is realized like this:
the interceptor for the injection mold is characterized by comprising an interceptor body, wherein one end of the interceptor body is provided with a fixed groove, the other end of the interceptor body is provided with a plurality of intercepting channels which can be communicated with a mold flow channel and have different sizes, an inlet of the intercepting channel is larger than an outlet thereof, and R angles at two sides of the outlet of the intercepting channel are in transition.
The shutoff device for the injection mold as described above is characterized in that the shutoff device body is in the shape of an elongated square.
The interceptor for the injection mold is characterized in that the fixing groove is internally provided with a concave platform.
The injection mold with the interceptor is characterized by comprising an upper mold base, an upper mold base plate and an upper mold, wherein the upper mold base is provided with a main runner, the upper mold is provided with a branch runner communicated with the main runner, the upper mold is also provided with an intercepting groove intersected with the branch runner, the interceptor body is slidably arranged in the intercepting groove, and a screw for fixing the interceptor body in the intercepting groove is arranged in a fixing groove of the interceptor body.
The injection mold is characterized in that the two sides of the tail end of the main runner are respectively provided with the branch runners communicated with the main runner, the upper mold is provided with the intercepting grooves vertically intersected with the two branch runners, and each intercepting groove is slidably provided with the intercepting device body.
The utility model has the advantages that:
one, the utility model discloses an equal smooth R angle transition of vatch channel has solved when the plastic fills
The problem of excessive shear force;
two, the utility model discloses a cooperation faying surface of cut-off passage and mould runner does not have the dead angle, prevents
The problems that cold glue and residual glue are trapped and then fall off and flush on the product are solved;
thirdly, the utility model discloses a cut-off channel is nimble adjustable, and minimum shelves are adjustable to being less than the gluey notes mouth on the product, reach the leading purpose of jiao kou to improve the injection line problem of some outward appearance A level face.
Fourth, the utility model discloses an injection mold has solved the too big problem of shearing force when the plastic fills, can prevent cold glue, incomplete glue pocket from staying, improves the injection line problem of some outward appearance A level face.
