In the market, most of the molds that come into contact with each other are injection molds, which are injected through plastic molds to form the required products for sale. In the mold industry, injection molds are commonly used. So what are the characteristics of injection mold?
Injection mold is a processing method used in mass production of parts, mainly used in industrial fields. The process of injection molding is that the materials which are melted by heat are injected into the mold cavity by high pressure and are cooled and solidified to obtain the molded product; Injection Mold the molding properties are divided into two types of thermosetting plastic molds and thermoplastic plastic molds. Features An injection mold can form a number of complex structure, size precision, intrinsic good quality plastic parts, plastic products in the production has been widely used. Characteristics of two design and manufacture, geometry and structure design of a reasonable size or not, a direct impact on the polymer melt flow in the mold channel characteristics and filling effect, Injection Mold and ultimately affect the molding quality of plastic parts. In the early design and development there are many uncertainties, first of all from the initial design requires experienced practitioners, most need to rely on the mold designer's knowledge and experience. Three characteristics such as jet flow, warpage, weld marks and the phenomenon of under-generation, are closely related with the design of the casting system. Fourth, control the mold temperature First, Injection Mold the mold heated to the working temperature, the second is to maintain a constant mold temperature at the operating temperature. The characteristics of the injection mold may be many, in the extensive use of plastic molds, the most common injection mold.
Injection molds are mainly divided into two parts: dynamic mold and fixed mold. It is divided into several categories according to molding process of injection mold, such as transfer mold, blow mold, Injection Mold casting mold, thermoforming mold, hot pressing mold and injection mold. Injection Mold It is by moving the mold installed in the injection molding machine moving the template, Injection Mold by moving the mold to make it closed with the fixed mold manufacturing plastic products.
Injection molds are important process equipment for producing various industrial products. With the rapid development of plastic industry, injection molds are generally used in important industrial sectors such as aerospace, electronics, machinery, ships and automobiles. With the widespread use of computers, Injection Mold plastic injection mold gradually toward data automation.
Due to the characteristics of injection molds, the temperature inside the injection mold is not uniform at all points, and this is mainly related to the injection cycle time. Thermal Balance Control of Injection Molds The heat transfer of injection molding machines and molds is the key to creating plastic parts, so it is important to keep the mold working at a constant temperature.
