Two-color injection molding machine types and characteristics analysis
The two-color injection molding machine is a machine that can produce two different materials and colors of plastic products. The two-color injection molding machine uses certain injection molding equipment and techniques to inject two different materials into the same set of molds to obtain the finished product. The two-color injection mold It is a plastic mold in which two plastic materials are injected on the same two-color injection molding machine, and then molded in two parts, but the product is only glued once. Such an operation is usually completed by only one set of molds and requires a special two-color injection molding machine. With the cooperation of the two-color mold, the two-color injection molding machine produces plastic products with two colors or materials, which improves the use experience and aesthetics of the finished product. two-color injection molding machines have relatively complex requirements for molds, and their structure and characteristics are somewhat different from those of single-color molds.
1. Types of two-color molds
Two-color molds can be divided into core rotation type, core retreat type, and push plate rotation type according to the structure. At present, the core rotation type is widely used in the market, and the core rotation split type in the core rotation type is the most widely used. The core rotation split type is used in two split molds on a set of injection molding machines. Alternate rotation to achieve injection molding of two-color products. The other form of the core rotating type is the core rotating conjoined type, and the conjoined type is to complete the injection molding of the two-color product in a pair of molds.
2. the characteristics of the two-color mold should have
Two-color molds are divided into a male mold and a female mold. The female mold is composed of two molds of different shapes to form a product, while the male mold is exactly the same two molds. The two female molds and the male mold are arranged in water. It needs to be as full as possible and balanced. In addition, the total thickness of the front mold panel plus A board cannot be less than 170mm, and must meet the parameter requirements of the corresponding injection molding machine model. The front and back molds of the two-color mold are in a straight line, and they must be completely coincident after rotating 180° from the center point. The nozzle of the three template should be designed with automatic demoulding action to avoid affecting the second injection.
In order to prevent the master mold from scratching the glue position of the first molded product during the second injection, a part of the space can be properly designed, and the strength of the sealant should be mastered to avoid deformation of the product under a larger impact.
3. the development of two-color molds
At present, two-color injection molding has been widely used in our lives, such as electronic products, toys, medical products, etc., so two-color molds are gradually being developed. With the continuous innovation of technology, multi-color injection molding machines have also come out and are developing rapidly. , Not only two-color molds,but also multi-color molds will be widely used in our daily lives.
