Description

Technical Field

[0001] This utility model relates to the technical field of rotational molding machine structure, specifically a rotational molding machine housing heating device. Background Technology

[0002] Rotational molding is a process for forming hollow plastic products, also known as rotational molding, rotational die molding, or rotary molding. This structure includes a corresponding heating structure for the rotational molding machine housing. For example, a rotational molding machine housing heating device, such as one described in patent publication number CN213440710U, uses a circulating air device in the middle of the lower mold. A rotating fan in the middle of this device generates airflow that blows into the interior of the lower mold. This circulating air replaces stirring, ensuring uniform material distribution, improving the reliability of the device, and guaranteeing the quality of the molded product. Furthermore, a vent is located at the bottom of the circulating air device, allowing moisture to escape to the outside, further enhancing the device's practicality. Furthermore, a lower support foot is set at the bottom of the lower mold to provide support, and a telescopic rod is set at the top of the lower support foot. The top of the telescopic rod passes through the bottom of the lower mold and is connected to the push plate, so that the telescopic rod can drive the push plate to rise and fall. Therefore, in use, you only need to drive the push plate to rise by the telescopic rod to push the molded device out of the lower mold for easy access.

[0003] However, in reality, the device needs to be manually removed and placed, which is cumbersome to operate and inconvenient to use. Utility Model Content
