disclosure of Invention
The invention aims to overcome the defects in the prior art and provides the clamping mechanism of the leather carving molding press, which has a simple structure and high precision.
In order to achieve the purpose, the invention adopts the following technical scheme:
A mold locking mechanism of a leather carving molding press comprises a supporting plate, an upper pressing plate, a lower pressing plate and two locking claw mechanisms, wherein the upper pressing plate is arranged right below the supporting plate, the lower pressing plate is arranged right below the upper pressing plate, and the lower pressing plate is provided with a mold cavity corresponding to the upper pressing plate; in a lock claw mechanism, including mode locking cylinder, bracing piece, first lock claw and second lock claw, the mode locking cylinder sets up in the backup pad, is equipped with two cylinder piston rods in the mode locking cylinder, and the mode locking cylinder is cut apart into three cavity by the cylinder piston rod that is in the mode locking cylinder, one of them cylinder piston rod one end is articulated with first lock claw one end, and another cylinder piston rod one end is articulated with the one end of second lock claw, bracing piece one end is articulated with first lock claw, and the bracing piece other end is articulated with second lock claw, and the bracing piece level sets up in the backup pad top. In the actual working process, when the upper pressure plate is turned to a position parallel to the die cavity, the middle cavity of the die locking air cylinder is inflated to extend out a piston rod of the air cylinder to prop against the locking claw, the locking claw rotates around the hinged position of the locking claw and the supporting rod to clamp the lower pressure plate and lift the lower pressure plate upwards to tightly press the upper pressure plate, and the die pressing work is carried out.
Preferably, the distance between the hinge joint of the first locking claw and the piston rod of the air cylinder and the hinge joint of the first locking claw and the supporting rod is between one half and two thirds of the length of the first locking claw. When the piston rod of the air cylinder stretches out, the locking claw can rotate around the hinged position of the supporting rod.
Preferably, the distance between the hinged part of the second locking claw and the piston rod of the air cylinder and the hinged part of the second locking claw and the supporting rod is between one half and two thirds of the length of the second locking claw.
Preferably, the outer side wall of the lower pressure plate is provided with clamping grooves which correspond to the claw heads of the locking claws one to one. The lower pressing plate is locked, the lower pressing plate can be tightly clamped by the locking claw, and the lower pressing plate is lifted upwards.
Preferably, the two locking claw mechanisms are arranged in parallel and are axisymmetric with respect to the support plate. When the locking claw lifts the lower pressing plate upwards and compresses tightly, the stress of the lower pressing plate can be ensured to be even, thereby reducing errors and ensuring the precision of leather carving.
Preferably, the length of the supporting rod is greater than the minimum distance between the two opposite ends of the two cylinder piston rods, and the length of the supporting rod is less than the maximum distance between the two opposite ends of the two cylinder piston rods. The locking claw can clamp the lower pressing plate when the piston rod extends out.
The invention has the beneficial effects that: increase clamping mechanism on prior art's basis, guarantee in hot pressing process, can reach certain accuracy to can guarantee that the skin carving atress is even, improve the roughness.
