Introduction to injection molding technology of toilet cover interlayer injection molding machine, production does not need to re-open the mold, do not produce toilet cover interlayer products can be used as a single color injection molding machine. Haiying toilet cover interlayer injection molding machine is equipped with twin screw barrel and specially designed compound nozzle to achieve innovative injection molding processing technology for the production of toilet cover interlayer. In the injection process, the surface plastic and the inner core plastic waste are injected into the mold hole to achieve double co-injection, of which the outer plastic plastic is called the cortex material, and the inner plastic waste is called the core material. Appropriate combination of the skin material and the core material waste can reduce the residual stress and increase the strength and appearance of the product. The mixed two-color injection molding machine can produce plastic products with special effects.

Curtain bead injection molding machine Function The machine can be injected into clouds or multi-level color products under the original configuration. It is only necessary to install a computer-controlled color mixer on the fixed template, and then connect with the mold when loading, it can have the function of color mixing injection molding. The injection order, number, glue amount, temperature, pressure, etc. of each injection system are controlled from the computer setting instructions, and then injected into the mold cavity through the color mixer that inputs the color mixing program in advance. Because the color mixer is very close to the mold water outlet, it is easy to obtain the desired effect during the injection mixing process. When using this function, there is no need to rotate the turntable, just set the "turntable use mode" to "Use color mixing" on the computer screen, and then equip the color mixer with adjustable mixing program.

The hydraulic transmission system takes hydraulic oil as the working medium, and its working medium directly affects the accuracy of the pressure and flow, the stability of the hydraulic system and the leakage amount. With the increase of temperature, the viscosity of hydraulic oil decreases. Therefore, the high temperature of the standard vertical injection oil will affect the pressure system of the oil, resulting in an increase in leakage, causing fluctuations in the system pressure and flow, causing fluctuations in the flow and pressure into the actuators, resulting in a variety of pressure and speed instability, causing instability in the production process, and ultimately affecting the molding quality of the product. With the increase of oil pressure, the molecular distance decreases, and the oil content increases with the increase of pressure, but the change range is small. Therefore, when the ambient temperature is high, high fat should be selected; Instead, choose low fat.

In the execution circuit of the hydraulic system, according to the main oil circuit of the two-color vertical injection molding machine and the role of each executive cylinder, the hydraulic components can form the control module of the hydraulic system to improve the integration degree of the system. Injection machine oil control module includes: pressure/flow control module (P/Q oil circuit module), injection/pre-molding control module, mold control module, ejection control module.
