AI Technical Summary
When injection molding plastic boxes, existing plastic box injection molds need to be opened on both sides as handles. However, due to the fragile plastic material, it is difficult to directly open holes during the injection molding process, resulting in increased production costs and prone to cracking of the plastic box.
An injection mold including a support plate, a mold, an adjustment assembly and a ticking assembly is designed. The twitching assembly drives the pulling plate and connecting rod to move through the electric push rod, and can directly open the handle opening during the injection molding process. The adjustment component adjusts the thickness of the bottom of the plastic box through extrusion blocks and bolts.
It realizes the direct opening of the handle when injection-molding plastic boxes, which reduces subsequent processes and reduces production costs. It also quickly adjusts the bottom thickness of the plastic boxes by adjusting the components, improving production efficiency.

The injection mold of plastic box is a tool specially used to produce plastic boxes. It adopts injection molding process to inject molten plastic material into the mold and obtain a plastic box of predetermined shape after cooling.
[0003] With existing plastic box injection molds, when injecting plastic boxes, some plastic boxes need to have grooves on both sides to serve as handles for easy use. However, the plastic boxes need to be punched after the injection molding is completed.

[0017] The beneficial effect of the utility model is that by setting up the pulling component, when injection molding plastic boxes, some plastic boxes need to be opened on both sides after processing to expose the handles for easy use and carrying by personnel, but most injection molds first inject a rectangle and then open the holes, which increases the working steps, and when opening the holes, the plastic material is brittle and prone to cracking, which increases the production cost. By using the pulling component, the handle opening can be opened when the plastic box is injection molded, which reduces the subsequent processes and reduces the cost. By setting up the adjusting component, when producing plastic boxes, the required bottom thickness is different, and the required thickness can be quickly adjusted by using the adjusting component, which is convenient to operate.
