Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an injection mold. The injection mold comprises a movable mold and a fixed mold. The movable mold comprises a mold base, a mold body arranged on the mold base and provided with a sealing glue surface, and an elastic sealing layer attached on the sealing glue surface. The movable mold can move relative to the fixed mold until the sealing glue surface butts against the innerwall of the fixed mold to form a mold cavity between the movable mold and the fixed mold. As the elastic sealing layer is attached on the sealing glue surface, and can be extruded for elastic deformation, the tightness of the mold cavity is better. The injection mold effectively reduces product burrs in the injection molding process. In addition, the invention further relates to a machining method of the movable mold; the sealing glue surface is polished and roughened; and the elastic sealing layer is formed on the roughened sealing glue surface, so that the attachment effect of the elastic sealing layer and the sealing glue surface is better. The movable mold prepared by the method cooperates with the fixed mold to effectively reduce the product burrs generated in the product injection molding process.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection mold and a processing method for a moving mold. Background technique [0002] Injection molding process, as a method of producing industrial products, is widely used in the production of various industries. However, in the traditional injection molding process, due to the poor sealing of the cavity of the mold, the material will overflow to form serious product burrs, which seriously affects the use and appearance of the product. [0003] Based on the consideration of reducing burrs, the mold sealing surface is generally made into a mirror surface to reduce the contact gap in the mirror area, thereby achieving the effect of increasing airtightness and reducing burrs. However, although the mirror surface reduces the contact gap, its airtight effect is still not very good, and the product still has rough edges. Contents of the invention [0004] Based on ...
