Pipe fitting molds are molds used to produce various shaped pipe fitting products. They are supporting tools used in the injection molding industry to shape pipe fitting materials. Do you know the development trends in the pipe fitting mold processing industry? 1. The gradual large-scale production of pipe fitting mold forming parts and the high production rate requirements lead to multi-cavity molds, resulting in the gradual large-scale of molds. Large molds with a tonnage of up to 100 tons can have hundreds or even thousands of cavities, requiring mold processing equipment with large work tables, increased Y-axis and Z-axis travel, high load capacity, high rigidity, and high consistency.
When we are processing motorcycle parts mold shells, we often encounter some problems, one of the more common ones being cracking. It is well known that the main cause of cracking is due to stress deformation, which can be mainly divided into residual stress, external stress, and stress deformation caused by the external environment. Therefore, to solve the cracking problem that occurs during the processing of plastic mold shells, we must start by addressing the stress.
High-gloss molds have very strict requirements for product structure. It is well known that the shinier the product, the more sensitive it is to light refraction effects. Any slight surface defect will be quickly noticed. Therefore, how to solve the shrinkage problem is the primary issue for high-gloss products. According to experience statistics, the thickness of the ribs in general products should not exceed 0.6 times the thickness of the main glue position to avoid shrinkage, or in other words, the shrinkage is small and not easily detected, which can be ignored. However, for high-gloss products, such requirements are far from sufficient. The thickness of the product ribs must be reduced to no more than 0.4 times the thickness of the main glue position, and special treatment must be applied to the screw column positions.
Beiben H06 Car Rearview Mirror Mold
The assembly drawing of the car rearview mirror mold shows that after the mold is closed, the injection molding machine begins to inject ABS into the cavity. After a period of holding pressure for forming, the rear mold starts to separate from the front mold along with the injection molding machine. When the front mold reaches its end position, under the effect of the pull rod and the core clamping force, the plastic part and the flowing condensed material remain on the moving mold. At this moment, the core pulling mechanism begins to drive the side sliding block to complete the lateral core pulling under the effect of the hydraulic cylinder. Under the effect of the ejection mechanism, the plastic part separates from the moving mold. Under the effect of the reset rod and the reset spring, the ejector rod returns to the position where the mold was closed. Finally, the mold closes, completing one working cycle.
