Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and more specifically, to a blister tray molding die. Background Technology

[0002] When producing PET material blister trays, they need to be formed using a blister mold. First, the substrate is heated, then the substrate is placed on the upper outer surface of the mold, and then air is drawn out so that the substrate can adhere to the mold.

[0003] In the prior art, the substrate is adhered to the inner wall of the mold cavity by air extraction. Due to the uniform distribution of the air extraction holes, the substrate can be adhered to the middle of the lower end of the mold cavity. Application No. 202421227056.6 discloses a PET material blister tray forming mold, including a forming mold assembly. A blister component is fixedly installed on the lower outer surface of the forming mold assembly. The forming mold assembly includes a mold plate, a forming cavity, a bottom forming plate, air extraction holes and an annular air channel. The blister component includes a base plate, a surrounding plate, a top plate, a connecting nozzle, an air extraction main pipe, a fixing frame, air extraction branch pipes, an expansion port, an air extraction chamber and a support column. The mold plate is fixedly installed on the upper outer surface of the top plate. The forming mold assembly of the above device is fixedly connected to the top of the blister component. It is not possible to flexibly disassemble and replace the damaged forming mold, which greatly reduces its practicality and service life. Moreover, after the forming and cooling, the operator needs to manually remove the blister tray from the mold cavity. The material removal operation will greatly increase the defect rate of the blister tray.
