[0002] The control panel is one of the important control components of electrical appliances. It mainly controls the electrical components in the appliance and is one of the indispensable components in the appliance. The material of the control panel is mainly plastic material. Therefore, it is mainly produced by injection molding during production. The production of the control panel needs to be operated through an injection molding mold.

[0003] However, the existing control panel injection molding mold requires manual removal of the control panel from the mold after the control panel is formed. The existing removal method mainly relies on prying with a prying piece. This removal method has high technical requirements for the operator. When removing the panel, it is very easy to cause damage to the edge of the panel, thereby affecting the integrity of the panel, causing great damage to the panel. In addition, the existing injection mold does not have the function of autonomous preheating or cooling. During injection molding, the high-temperature raw material is easily solidified instantly when it contacts the cold mold, resulting in quality defects in the panel. After the injection molding is completed, the panel cooling time is too long, affecting the progress of the next process. Utility Model Content
