This application arranges electric heating wires on the outer side walls of the upper mold and the lower mold, and during the rotational molding operation, the upper mold and the lower mold are heated by the electric heating wires, and the heat energy generated by the electric heating wires is directly transmitted to the upper mold and the lower mold, which can effectively reduce the loss of energy. At the same time, the cost of electric energy is also lower, which has the effect of reducing production costs.

[0003] The existing rotational molding molds are not easy to assemble and disassemble. Generally, the top mold and the bottom mold of the rotational molding mold are fixed with multiple bolts. When adding materials and demoulding, the mold needs to be installed and disassembled. When disassembling and assembling, tools are needed to disassemble and assemble multiple bolts. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. It is also not convenient to replace the heating rod. The heating rod will be damaged after long-term use and needs to be replaced. Generally, the heating rod is installed inside the mold through threads. When replacing, it is necessary to open the mold and use tools to disassemble and assemble the heating rod, which is very troublesome. The replacement steps are relatively cumbersome, which increases the workload and reduces the replacement efficiency. In order to solve the above-mentioned problems, we propose a heating type rotational molding mold. Utility Model Content
