Structural composition
Forming parts: determine the shape of tweezers, etc., composed of core, cavity, commonly used P20 and other high-quality die steel, cutting, wear resistance and other properties.
Pouring system: including the main channel, diverter channel, gate, cold hole, the role is to connect the injection molding machine, guide the melt, control the flow rate, collect cold material.
Guide part: composed of guide column and guide sleeve, it is installed in the dynamic fixed mold to ensure the accuracy of mold closing and help demoulding.
Launching mechanism: After injection molding, tweezers are launched, common push-rod, push-tube and other forms, composed of push-rod, etc., to ensure uniform pushing force.
Lateral parting and core-pulling mechanism: used for tweezers with side holes and side pits, composed of sliders, etc.
Cooling system: The mold is provided with a water channel, and the circulating water is used to dissipate heat, so that the tweezers can cool quickly and ensure the uniform temperature of the mold.
Design essentials
Parting surface: Choose in the largest contour, avoid holes, grooves, do not affect the appearance of performance.
Gate: Select the right type and position according to the tweezers, such as side gate can reduce the weld mark.
Cooling system: reasonable arrangement of the water channel to ensure uniform temperature, complex tweezers or need special cooling.
Manufacturing process
Roughing: CNC machine tools to spare, for finishing.
Finishing: Precision and surface quality are guaranteed with high-precision equipment.
Surface treatment: nitriding, hard chrome plating, improve mold performance, prolong life.
Assembly and debugging: assembly after cleaning and deburring, adjust the mold, check the problem and repair.
