Injection mold

Abstract

The invention discloses an injection mold which comprises an upper die, a lower die, an injection molding opening and an injection molding runner, wherein the upper die and the lower die both adopt symmetric concave cavity structures; after the upper die and the lower die are combined with each other, a die cavity is formed in the mold; the injection molding opening is formed in the top of the upper die and is communicated with the injection molding runner; the upper die and the lower die are also provided with balance blocks and vibration motors; the vibration motors are respectively arranged on the balance blocks. By the arrangement of the balance blocks and the vibration motors, the injection mold provided by the invention guarantees the equilibrium and is unlikely to shake; meanwhile, the uniformity of injection molding materials in the injection mold is guaranteed, the quality of a product subjected to injection molding is improved, the labor intensity of an operator is alleviated, and harm to the safety of the operator, caused by sputtering of the materials in a vibration process, is prevented.

Description

technical field [0001] The invention relates to the field of molds, in particular to an injection mold. Background technique [0002] At present, when the material is injected, since the injection material will condense in a very short time, in order to ensure the quality of the injection molding and remove the air contained in the injection material, it is necessary to vibrate the injection material. Now, manual vibrating rods are generally used for manual vibration. In this way, the average vibration time is 270s ~ 310s, the vibration time is too long, and the labor intensity is high. At the same time, due to the difference in personal experience and the difference in operation level, it is easy to cause unevenness of the injection material during the injection molding process. On the one hand, if the injection plastic is too thick, the vibration will not be dense, and it is easy to form pores, which will reduce the overall performance of the injection plastic and easily ...

[0002] At present, when the material is injected, since the injection material will condense in a very short time, in order to ensure the quality of the injection molding and remove the air contained in the injection material, it is necessary to vibrate the injection material. Now, manual vibrating rods are generally used for manual vibration. The way, the average vibration time is 270s ~ 310s, the vibration time is too long, the labor intensity is high

At the same time, due to the difference in personal experience and the difference in operation level, it is easy to cause unevenness of the injection material during the injection molding process.

On the one hand, if the injection compound is too thick, the vibration will not be dense, and it will easily form pores, resulting in a decrease in the overall performance of the injection compound, and it will easily form transverse cracks when it is dry; Easy to form cracks during baking

The injection material is loaded into the mold twice, and the artificial vibration takes a long time, which may easily cause the injection material in the middle to be weakly bonded, thus affecting the strength of the injection molded body.
