Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an automatically lifted luminous character mold. Background Art

[0002] Luminous characters are luminous signs made of a character shell, a panel, and a base plate. Luminous characters are colorful and personalized, making the signs more humane and playing an important role in promoting enterprises, stores, and exhibitions. The current traditional process of luminous characters is to process the plate body with a CNC engraving machine. This processing method makes the processing speed slow and wastes a lot of materials. Therefore, in order to improve the processing efficiency of acrylic luminous characters, there are technologies that propose related processing molds to assist the production of acrylic luminous characters. For example, there is a utility model patent with a publication number of CN208745124U, which proposes an acrylic luminous character production mold, which uses a mold to replace the CNC engraving machine for production, and pours liquid acrylic on the formed mold to directly obtain the desired product. The molded acrylic luminous characters are taken out using an ejector assembly to prevent scratches on the product surface and improve the removal efficiency. The acrylic glue is poured according to the lines of the graphic through the mold forming, and there is no waste of materials and the processing efficiency is high.

[0003] From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to the ejection of the product after molding. However, according to the description in the above disclosed technical content, after the curing is completed, the ejector plate is pushed and the ejector pin ejects the product from the cavity. The processing efficiency is high and the labor cost is greatly reduced. At this time, the movement of the ejector pin inside the ejection hole is controlled by the staff's manipulation of the ejector plate, so that the ejector plate moves up and down in the vertical direction inside the ejector plate groove. This method of controlling the ejector plate will increase the workload of the staff for controlling the ejector plate. At the same time, after the processing of the luminous character mold is completed, it is necessary to wait for the staff to push the ejector plate, which will increase the time for ejection after the luminous character is formed, thereby reducing the efficiency of the luminous character processing.
