Description

Technical Field

[0001] The present invention belongs to the technical field of blister molding machine molds, and specifically relates to a mold quick-change device for a large blister molding machine. Background Art

[0002] Blistering is a plastic processing technology. The main principle is to plasticize and extrude the plastic raw materials through high-temperature heating to form a soft sheet. The sheet is sent to the mold part of the blister production line through a conveyor belt, and is vacuum-adsorbed on the mold surface and then cooled and formed. The semi-finished product is then transported to the die-cutting part via a conveyor belt to be cut into a finished product.

[0003] In order to improve the production adaptability of the blister machine, most large blister machines use replaceable molds to replace the molds, so as to facilitate the production of blister products of various shapes.

[0004] However, due to the large size of the large blister machine itself, when the mold needs to be replaced, it is necessary to manually insert half of the body into the blister machine to replace it. Since the blister machine itself is a downward pressure hydraulic punch, it is very dangerous to manually insert the inside of the blister machine to replace the mold. In addition, in order to meet the rapid blister forming of the blister machine and prevent overheating damage, rows of jet nozzles for cooling are provided on the outside of the large blister machine. In order to achieve a better cooling effect, these nozzles are set in the middle of the upper and lower openings of the blister machine, and are also arranged on the outside of the blister machine in a surrounding manner. Therefore, in the process of replacing the mold, these nozzles will make it very troublesome to change the mold and cause interference. Summary of the invention

[0005] In order to solve the above problems, this paper proposes a mold quick-changing device for a large-scale blister machine. The mold quick-changing device is introduced from the side of the blister machine and is plugged in on the inner side of the blister machine. A positioning guide column is provided at the bottom of the side of the blister machine.

The mold quick-changing device includes a quick-changing trolley, a mold support disassembly plate and a gap disassembly plate. The quick-changing trolley is a vertical plate-type lifting and lifting trolley. The front of the quick-changing trolley is longitudinally protruding and is provided with a mold support disassembly plate and a gap disassembly plate. The bottom of the front of the quick-changing trolley is provided with a positioning hole. The mold support disassembly plate is transversely axially symmetrically arranged on the upper and lower sides of the front of the quick-changing trolley. The mold support disassembly plate is vertically connected to the quick-changing trolley through a vertical moving groove. The outer surface of the mold support disassembly plate is symmetrical on both sides. A gap disassembly plate is provided, and a disassembly blade is provided on the inner edge of the gap disassembly plate. The gap disassembly plate is connected to the quick-change trolley for horizontal movement through a horizontal moving groove. The shape of the mold support disassembly plate is a rectangular groove step-type plate. A plurality of bolt disassembly holes are provided at the outer edge of the outer surface of the mold support disassembly plate.
