Detailed Description

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings.

Referring to fig. 2 to 4, the present utility model provides a vertical housing plastic mold core, which comprises a molding housing 1 and an inner mold core 2, wherein the inner mold core 2 is installed in the molding housing 1, a cavity gap between the molding housing 1 and the inner mold core 2 is a molding cavity, the inner mold core 2 comprises a bottom plate 21 and a core 22, the bottom plate 21 is arranged at the bottom of the core 22 and is used for shielding a bottom opening of the molding housing 1, and one side of the core 22 corresponding to a vertical edge of the vertical housing is arranged in an inclined manner;

When the plastic mold core is used, high-temperature melted plastic raw materials are injected into a molding cavity to realize molding, the vertical edge of the vertical shell primary blank molded in the molding cavity is inclined outwards, and after the vertical shell primary blank is taken out of the mold, the vertical edge of the vertical shell primary blank contracts and deforms under the influence of room temperature to keep the vertical state, so that the plastic mold core is provided, and the vertical state of the vertical shell can be kept after demolding.

In this embodiment, the core 22 includes a main core 221 and a side core 222, the side core 222 is detachably mounted on a surface corresponding to a vertical side of the main core 221 and the vertical shell, and a bevel is provided on a surface of the side core 222;

When the vertical shell blank is used, the vertical edge of the vertical shell blank formed in the forming cavity is inclined outwards through the inclined surface of the side core 222, so that the vertical edge of the vertical shell blank is contracted and deformed under the influence of room temperature after the vertical shell blank is taken out of the die, and the vertical state is maintained; and the side core 222 which can be detached and replaced can be adjusted and replaced according to the plastic raw materials, so that the adjustment of shrinkage amplitude of different plastic raw materials during cooling is satisfied.

In this embodiment, the inclined surface is an inclined surface inclined from bottom to top toward the main core 221.

The working principle of the utility model is as follows:

The high-temperature melted plastic raw material is injected into the forming cavity to realize forming, the vertical edge of the vertical shell primary blank formed in the forming cavity is inclined outwards, and after the vertical shell primary blank is taken out of the die, the vertical edge of the vertical shell primary blank contracts and deforms under the influence of room temperature to keep the vertical state, so that the plastic die core capable of keeping the vertical state after demolding is provided.

The circuit, the electronic components and the modules are all in the prior art, and can be completely realized by a person skilled in the art, and needless to say, the protection of the utility model does not relate to the improvement of software and a method.
