Abstract
The utility model discloses a demolding mechanism for a vacuum plastic-absorbing forming die for an inner liner of a refrigerator. The demolding mechanism comprises an air cylinder installed at the upper part of a die body and two core-pulling blocks distributed on two sides of the axial line of the air cylinder; two guide rails are fixed on two sides of the die body, sliding blocks are arranged in the guide rails in a sliding manner, and the two core-pulling blocks are respectively fixed on the two sliding blocks; and simultaneously, push plates are also fixed on the two sliding blocks, and two supporting plates fixed on the air cylinder are respectively used for supporting the two push plates. Due to the use of the guide rails and the sliding block mechanisms, the core-pulling blocks can realize the separation between the same die bodies by fully using the dead weight during the demolding process; and compared with the prior demolding mechanism for directly driving the core-pulling blocks through the air cylinder and the connecting rod, the change in speed of the core-pulling blocks is small, the actions are more stable, and the manufactured product can be effectively prevented from being strained; and compared with the prior demolding mechanism, the utility model has the advantages of simple integral structure and lower maintenance cost.
