What are the components of the two-color mold structure? The two-color mold is a mold in which two types of injection molding equipment are molded in two times by one injection molding processing equipment, but the product is only released once. This kind of mold is also called double-material injection molding. Compared with overmolding, two-color molds only need one set of molds, and special two-color injection molding equipment is required. Two-color molds can make the appearance and color of the product more beautiful, and it is easier to change the color, so it is often used in products with high requirements for appearance and color. It does not need to be sprayed, but the technical requirements are high and the structure is relatively complicated. So, what are the components of the two-color mold structure? Shanghai Mulan has served Japanese brands for more than 10 years, and has been focusing on the finished product customization business of small electrical appliances, household beauty instruments, and maternal and child products. Two-color mold structure gives a detailed introduction:

The common two-color mold structure is the middle plate mold structure: the two moving mold parts of this two-color mold structure are exactly the same. Due to the needs of the product mold process structure, the two movable molds are required to be different, and there is no need to use a side core-pulling mechanism. The working principle of this mold structure is that during the two-color injection molding process, the two pairs of movable molds do not rotate. After the injection molding processing equipment completes an injection molding action, the fixed and movable molds are opened, and the middle plate is first ejected, and then the middle plate is rotated 180 degrees. degree, and then close the mold for secondary molding.

In addition, there are twin structures and seesaw structures. The twin structure means 2 molds. The mold design process only has one mold base. According to the position of the barrel of the injection molding processing equipment to determine the 2 glue inlet points, it is necessary to design two nozzles in different positions. The seesaw structure is that two sides revolve around the axis of rotation, one side moves up, and the other side moves down, and so on, and the cycle is repeated. Only by adopting the seesaw structure can the secondary material flow into the closed area smoothly and form a beautiful appearance.
