Belt injection mold

Abstract

The invention relates to the technical field of belt injection molds, and discloses a belt injection mold. The belt injection mold comprises a supporting bottom plate. A fixing plate is arranged abovethe supporting bottom plate. Ejector pin guide rods are arranged in ejector pin sleeves. A lower mold is arranged above the ejector pin sleeves. A damping device is arranged on the side, close to thefixing plate, at the upper end of the supporting bottom plate. An upper mold is arranged at the upper end of the damping device and is above the lower mold. According to the belt injection mold, dustcan be prevented from entering the mold, the quality of a produced belt can be improved, harmful gas caused by melt due to high temperature can be filtered, harm to a human body by the harmful gas can be reduced, the upper mold can be buffered during mold closing, severe shaking of the mold during mold closing can be prevented, the service life of the mold can be prolonged, noise caused by quickmold closing can be effectively reduced, the discharged melt can be stored, economic cost can be reduced, and workers can be prevented from empyrosis due to the high-temperature melt.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a belt injection mold. Background technique [0002] Injection molding is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the molded product is obtained. [0003] Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, the hot pressing mold can be divided into three types: overflow type, semi-overflow type and ...

AI Technical Summary

Problems solved by technology

In order to reduce the heavy workload of mold design and manufacturing, most injection molds use standard mold bases, and belt manufacturing is based on the process of injection molds; traditional belt injection molds have many disadvantages. First, the mold will enter dust from the injection port when it is not in use. Some of the products obtained contain impurities. Secondly, the belt will generate a lot of harmful gas due to heating during the injection molding process, and the mold will vibrate violently when closing the mold, which will reduce the service life of the mold. In addition, some gas will be discharged from the vent hole. The high-temperature molten material is easy to burn the staff and cause waste. Therefore, we propose a belt injection mold
