It is one of the most widely used decorative materials in plastic materials.

[0003] A plastic mold is a tool for shaping objects, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of an object by changing the physical state of the formed material. With the continuous development and progress of science and technology, plastic formed products are widely used in decorative panels for interior decoration. The plastic formed decorative panel has various wood grains or patterns, is bright, flat, has bright and beautiful colors, and at the same time has good physical properties such as high wear resistance, heat resistance, cold resistance, and fire resistance.

[0004] After the existing decorative panel is plastic formed, it is necessary to quickly separate the decorative panel from the plastic mold to avoid the adhesion of the four sides of the decorative panel to the mold after cooling, resulting in difficulty in separating the decorative panel from the mold. However, since the temperature of the decorative panel is relatively high and not yet shaped after plastic forming, when manually separating the decorative panel from the mold, it is easy to cause deformation of the decorative panel and scalding of the operator's hands, reducing the safety and qualification rate of factory production. In view of the above problems, a plastic mold for PVC decorative panels is proposed. Content of the Utility Model

At this time, it can be avoided that when the formed PVC decorative plate is ejected, the formed PVC decorative plate is easily adhered to the outer wall, resulting in difficult demolding. Using this method, not only the demolding is simple, but also the appearance of defective products is reduced during demolding, which is more convenient. Moreover, for the plastic mold for PVC decorative plates, the formed PVC decorative plate can be ejected through the electric push rod and the ejecting block to complete demolding. Compared with the traditional manual demolding method, this demolding method is more convenient and efficient.

[0039] Working principle: When this PVC decorative board uses a plastic mold, plastic is injected into the plastic mold frame 1, and it is sealed by the upper sealing plate 2 on the plastic mold. After the PVC decorative board is formed, by starting the motor 11, the motor 11 outputs power to the threaded rod 8 fixedly installed at the output end through operation to make it rotate. At this time, the moving block 9 sleeved on the outer surface of the threaded rod 8 continuously moves downward through the thread provided on the outer surface of the threaded rod 8. At the same time, the four fixing plates 10 fixedly installed on the outer surface of the moving block 9 slide downward on the inner surfaces of the four sliding grooves 7. At the same time, the four fixing plates 10 drive the four sliding plates 12 fixedly installed at the opposite ends to move downward. At the same time, the four sliding plates 12 drive the four vertical plates 13 fixedly installed on the upper surface to slide downward. At this time, the vertical plates 13 around the PVC decorative board move downward after being formed, and no longer restrict the periphery of the PVC decorative board after being formed. At this time, by starting the electric push rod 14, the electric push rod 14 applies an upward thrust to the four ejector blocks 15 fixedly installed at the upper end through operation to make them move upward. At this time, the formed PVC decorative board is ejected by the four ejector blocks 15, and the demolding can be completed.
