The pallet mold utilizes injection molding technology. Its working principle involves heating plastic granules to a molten state, injecting them into the mold cavity under high pressure, and then demolding after cooling and solidification to form the finished product. The mold structure includes several key components:
1. Cavity and Core: Determines the pallet's shape and internal structure. Multi-cavity designs allow for the simultaneous production of multiple pallets, improving efficiency.
2. Parting Surface: The contact surface where the mold separates when opened. Multiple parting surfaces optimize the demolding process and reduce the risk of product deformation.
3. Gating System: The channel that guides molten plastic into the cavity. The runner layout must be designed according to the pallet size to avoid material waste.
4. Cooling System: Controls the mold temperature through a circulating water system to ensure rapid and uniform solidification of the plastic, shortening the production cycle.
