Problems solved by technology

[0003] In the prior art, when making a car antenna through an injection mold, because of the structure of the car antenna itself, for example, a texture structure is provided on the outside of a columnar body. Yes, after the injection molding is completed, it will be stuck in the cavity, and it is difficult to take out the molded product. If you take it out forcibly, it is very likely to damage the molded product, which will prolong the production time and increase the defective rate of production.

Embodiment 1

[0047] like Figure 1-9 As shown, the automotive antenna injection mold provided in this embodiment includes a front mold 10 and a plurality of rear molds; the plurality of rear molds are compressed and closed with the front mold 10 in sequence to form a plurality of different cavities, and a plurality of different mold cavities are formed. The cavities can be injected separately to form antennas of different shapes.

[0048] Specifically, the automotive antenna injection mold includes a front mold 10 and a plurality of rear molds, and each rear mold can be compressed and closed with the front mold 10 to form different cavities, and different cavities can be used to mold different shapes of antennas.

[0049] Among them, a plurality of rear molds should be pressed and closed with the front mold 10 in sequence, for example, the previous back mold and the front mold 10 are pressed and closed to form a smooth cavity structure. An antenna with a smooth surface can be obtained by ...

Embodiment 2

[0082] This embodiment also provides an injection mold, including the above-mentioned automobile antenna injection mold.

[0083] Specifically, the injection mold can be molded twice to form an injection molded product, which solves the problem that it is difficult to release the mold or even damage the molded product due to structural problems on the product that needs to be injected.

Abstract

The invention provides an injection mold for an automobile antenna and an injection mold, and relates to the technical field of mold manufacturing. The injection mold for an automobile antenna includes a front mold and a plurality of rear molds; the plurality of rear molds are respectively pressed tightly with the front molds in sequence Closed to form a plurality of different cavities; different cavities can be injected to form antennas of different shapes, which alleviates the technical problems in the prior art that the structure of the car antenna itself is difficult to take out from the cavity after injection molding is completed.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an injection mold for an automobile antenna and an injection mold. Background technique [0002] The car antenna is also called the car antenna, which refers to the mobile communication antenna designed and installed on the vehicle. It is generally used for the radio and radio station on the car. It can be divided into a car built-in antenna and an external antenna, and other antennas can also be installed according to different purposes of the car. . Automobile antennas are generally manufactured by injection molding. Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise size. cavity, after cooling and solidification, a molded product is obtained. [0003] In the prior art, when making a car antenna through an injection mold, because of the structure of the car antenna itself, for ...
