Abstract

The invention discloses a locking and safety protection mechanism of a slush molding machine die and a powder box. The locking and safety protection mechanism is composed of a cylinder seat, a locking cylinder, a safe cylinder and a detection proximity switch, wherein the locking cylinder and the safe cylinder both are mounted on the cylinder seat; the locking cylinder is located at the rear part of the cylinder seat; the safe cylinder is located on the side part of the cylinder block; a locking pin penetrates through the cylinder seat; a pin sleeve is sleeved between the locking pin and the cylinder seat; the tail part of the locking pin is in threaded connection with the piston rod of the locking cylinder; a stepped groove is formed on the side surface of the locking pin; a pin hole is formed on the side surface of the cylinder seat; a guide sleeve is sleeved in the pin hole; a safety pin penetrates through the guide sleeve; the tail part of the safety pin is connected with the piston rod of the safe cylinder; the front part of the safety pin can be located in the stepped groove of the locking pin to lock the locking pin so that the locking pin is incapable of retracting; the detection proximity switch is arranged at the rear part of the cylinder seat, and used for detecting the retraction state of the locking pin; therefore, the safety of operation is improved; and the lower part of the front end of the locking pin is provided with an inclined surface so as to guarantee that the locking pin can be locked and unlocked smoothly, so that tight locking phenomenon is prevented.

Description

technical field [0001] The invention relates to a locking and safety protection mechanism for molds and powder boxes of slush molding machines. Background technique [0002] At present, the locking and safety protection mechanism used by the slush molding machine is made of PP polypropylene, which has poor wear resistance and frequent replacement; the gap between the locking pin and the body is too large, and the powder is easy to enter, and locking often occurs There is a phenomenon that the safety pin cannot be opened; the existing locking and safety protection mechanism does not have a device for detecting the state and position of the locking pin, and does not know the locking state of the mold of the slush molding machine and the powder box. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the locking and safety protection mechanism used by the slush molding machine, and provide a locking and safety protection...
