Rapid die clamping device for die casting machine

Abstract

The invention relates to a rapid die clamping device for a die casting machine. The rapid die clamping device for the die casting machine comprises a template arranged on the die casting machine, wherein rapid clamping mechanisms capable of clamping the die are arranged on the template; each rapid clamping mechanism comprises a driving component arranged on the side wall of the template; the template is provided with a channel corresponding to the driving component; a locking connecting rod is arranged on the channel in a sliding mode; the head end of the locking connecting rod is connected with the driving component; the tail end of the locking connecting rod is provided with a locking column which can extend into the die and is clamped with the die; the locking column is a conical column, a triangular pyramidal column, a wedged column or a trapezoidal column; the rapid clamping mechanisms are symmetrically arranged on the left side wall and the right side wall of the template; and 2to 8 rapid clamping mechanisms are arranged. By the rapid die clamping device, the template of the die casting machine can be rapidly clamped with the die; and each rapid clamping mechanism has the clamping force close to that of the corresponding locking block, so the die can be prevented from being loosened or displaced and the die is connected with the template safely and reliably.

Description

technical field [0001] The invention relates to a die-casting machine, in particular to a die quick clamping device for a die-casting machine. Background technique [0002] The mold is fixed on the template of the die-casting machine, usually by means of screw connection or clamping. [0003] The method of fixing with screws needs to adopt more screws for fixing, which is very time-consuming. [0004] The method of clamping with clamping device has the highest rate of adoption. Since this method requires a blank holder around the mold, it not only occupies the mold volume area of ​​the template, but also its clamping force depends on the strength of the operator to tighten the screws. Each clamping mold There is a large difference in the clamping force of the tool, so it is easy to cause the mold to shift, increase the reject rate, and even damage the mold and machine. Contents of the invention [0005] The purpose of the present invention is to provide a simple and reas...
