[0010] Example 1
[0011] The present invention is a multifunctional TV back shell mold, which includes an upper mold 1, a lower mold 2, a glue injection hole 3, and a molding cavity 4, and is characterized in that it further includes a heat dissipation protrusion 5, a heat dissipation recess 6, and a heat preservation layer 7. The heating layer 8, the air vent 9, the flowing water cooling layer 10, the upper mold 1 and the lower mold 2 are buckled together by a fixed structure to form a molding cavity 4. The upper mold 1 is provided with heat dissipation protrusions 5, heat dissipation protrusions 5 and lower molds. The heat dissipation recesses 6 on the mold 2 are matched. The upper mold 1 is sequentially provided with a heating layer 8, a flowing water cooling layer 10, and a heat preservation layer 7, and the lower mold 2 is also sequentially provided with a heating layer 8, a flowing water cooling layer 10, and a heat preservation layer. 7. A glue injection hole 3 is opened...
Example Embodiment
[0012] Example 2
[0013] When in use, first buckle the upper mold 1 and the lower mold 2 together, and fix the heat dissipation protrusion 5 and the heat dissipation recess 6 together to achieve a good fixing effect. The injection hole 3 injects the raw materials into the molding cavity 4, and turns on the heating The heater in layer 8 heats the raw material, and the heat preservation layer 7 heats the raw material. During injection molding, the gas in the molding cavity 4 is discharged out of the cavity through the vent 9 to ensure the quality of the product. When the injection is completed, the injection is stopped Then, the cold water is injected into the flowing water cooling layer 10 through the water injection hole, and the cold water flows through the flowing water cooling layer 10 and is discharged to the outside through the drainage hole.
