Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0025] Such as Figure 1-5 Shown:

[0026] An injection mold for producing a set-top box shell, comprising an upper mold assembly 1, a lower mold assembly 2, and an internal thread forming assembly 3, and the upper mold assembly 1 includes a top plate 11, an upper backing plate 12, an upper mold core 13, and a lower mold assembly 1. The mold assembly 2 includes a base plate 21, a left support seat 22, a right support seat, a lower backing plate 23, and a lower mold core 24. The upper mold core 13 and the lower mold core 24 cooperate to form a cavity 4, which is molded after mold clamping and injection molding. 1. After cooling, the set-top box shell 9 will be molded in the cavity 4, and there is a cavity 5 between the left support base 22 and the right support base, and the internal thread...

Abstract

The invention discloses an injection mold for producing a set top box shell. The injection mold comprises an upper mold assembly, a lower mold assembly and an internal thread forming assembly, wherein the upper mold assembly comprises a top plate, an upper base plate and an upper mold core; the lower mold assembly comprises a bottom plate, a left supporting seat, a right supporting seat, a lower base plate and a lower mold core; the upper mold core and the lower mold core are matched to form a mold cavity; a cavity is formed between the left supporting seat and the right supporting seat; and the cavity internal thread forming assembly is located on the inner side of the cavity. According to the injection mold, the set top box shell with a plurality of mounting holes can be produced, subsequent drilling forming is not needed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for producing set-top box shells. Background technique [0002] Such as figure 1 The shown set-top box casing 9 has a plurality of mounting holes 91, which are generally manufactured by an injection mold after being injected and then drilled. The process is cumbersome and the production efficiency is low. In addition, there is usually residual material at the nozzle position during the injection molding process. Generally, after the subsequent mold opening and ejection of the set-top box shell 9, it is necessary to manually cut the nozzle of the set-top box shell 9 to remove the residual material at the nozzle. This processing method also has production efficiency. lower question. Contents of the invention [0003] In view of the above problems, the present invention provides an injection mold for producing set-top box shells, which can produce set-...
