How to improve the quality of pipe fitting mold?

The manufacturing process of pipe fitting mold is a complex process, including design, processing, assembly, commissioning and other steps. In the entire production cycle, what factors will affect the quality of pipe fitting mold? How to improve the quality of pipe fitting mold?

1. Mold steel is the decisive factor for the quality of pipe fitting molds. How to choose the right mold steel?
(1)Determined according to raw materials. For example, PVC pipe fitting mold uses corrosion-resistant mold steel.
(2)Considering the cost of pipe fitting mold, the mold steel should be selected according to the service life. Generally, the life of P20 is about 300,000; 2738 is about 500,000; H13 / 2344 is usually more than 800,000 to 1 million.
(3)The surface treatment of the mold is also very important. Nitriding, can enhance the surface hardness of steel and effectively extend the life of the mold. Electroplating, for some molds that need to produce corrosion-resistant plastic parts, electroplating can be used to enhance and improve the properties of steel.

2.Structural design. The pipe fitting mold with mature structure design not only takes into account the differences of various materials (shrinkage rate, molding temperature, elastic tensile deformation coefficient, etc.), but also takes into account the cooling water path, the speed of opening and closing the mold, etc.

3. Mold processing. The arrangement of the mold process is particularly important. A reasonable process arrangement can speed up the production cycle and effectively save costs. The final polishing process also directly affects the surface and accuracy of the product. It can be said that this step can directly reflect the strength of pipe fitting mold manufacturer.

4. Cooling. In the mass production of pipe fittings, the profit brought by reducing the injection cycle is unimaginable. However, speeding up the production cycle will cause the mold temperature to rise, making the mold too hot to produce, and even causing mold deformation and scrap. Therefore, the design of an excellent cooling system is particularly important, including the density, diameter, and interconnection of water channels.

5.Mold maintenance. Mold maintenance is mainly maintenance and maintenance in the production process. After each use of the mold, comprehensive maintenance is required. Be sure to keep the mold dry, and then brush it with a layer of oil to prevent the mold from being damaged due to rust.
