What are the basic knowledge of plastic mold structure?

Plastic mold structure refers to the composition and structure of molds used to make plastic products. It mainly includes 9 aspects such as mold base, mold cavity, mold core, porting portal system, and cooling system.

The basic knowledge of plastic mold structure is introduced in detail below:

(1) Mold base: The mold base is the main support part of the mold, usually made of steel plates or cast iron. It provides the stability and rigidity of the mold to ensure that the mold will not be deformed or vibrated during use.

(2) Mold cavity: The mold cavity is an empty cavity for forming plastic products. Its shape and size are consistent with the final product. The mold cavity can be divided into upper and lower cavity, and the product formation is achieved through the cooperation of the upper and lower cavity.

(3) Mold core: The mold core is used to form a part of the cavity inside the plastic product. Its shape and size are consistent with the internal structure of the final product. The mold core is usually located inside the mold cavity, and the product molding is achieved through the cooperation of the mold cavity and mold core.

(4) Put the port system: The porting system is a part used to inject melting plastic materials. It includes the main pouring mouth, a pair of watering mouth, and auxiliary pouring mouth. The main watering port is the main channel for the molten plastic material to enter the mold. The pouring port and the auxiliary watering port are used to assist the filling mold cavity and core.

(5) Cooling system: The cooling system is a part used to control the temperature of the mold. It includes cooling water channels and jellynes. Cooling water channels absorb the heat generated in the mold by circulating cooling water to keep the mold within the appropriate temperature range.

(6) The exhaust system: The exhaust system is used to eliminate the part of the gas generated in the mold. During the injection molding process, the melting plastic will produce gas. If it is not excluded in time, it will cause bubbles or defects. The exhaust system is excluded by the exhaust tank, exhaust holes, etc. to achieve gas elimination.

(7) Positioning system: The positioning system is a part used to ensure the accurate positioning of the mold cavity and core. It includes positioning, positioning, and positioning board. The positioning system can keep the mold cavity and core in the correct position when closed to ensure the consistency of the size and shape of the product.

(8) Emailing system: The shooting system is used to inject the molten plastic material into the mold. It includes a tank, a mouth, and a shooting mechanism. By controlling the pressure and speed of the ejection cylinder, the molten plastic material is pushed into the mold cavity and core.

(9) Decarry system: The departure system is the part used to remove the molding products from the mold. It includes top -out rods, top boards, and top -out institutions. The molding system pushes the molding product from the mold cavity through the role of the top of the pole, so that the next step is processed and packaged.

To sum up, the basic knowledge of plastic mold structures includes mold base, mold cavity, mold core, portal pouring system, cooling system, exhaust system, positioning system, shooting system, and departure system. These components cooperate with each other to complete the molding process of plastic products together. Understanding and mastering these basic knowledge is essential for design and manufacturing high -quality plastic molds.
