Embodiment Construction

[0013] Such as figure 1 As shown, the present invention provides a mold locking device capable of withstanding relatively large impacts, including a punch holder 3 and a mold 4 installed in the punch holder, the mold and the punch holder A locking jackscrew 2 is arranged between them, the head of the locking jackscrew is screwed with a locking gear 1, and the locking gear is meshed with a locking rack 7, and the locking rack 7 passes through the support rod 5 is erected on the rack support 8, and the locking rack can rotate around the support rod.

[0014] A limiting rod 6 is screwed on the rack support.

[0015] The rack support is fixed on the punch holder by screws.

[0016] The working principle of the present invention is as follows: the mold is installed in the punch holder, and the front and rear movement is limited by locking the top wire. The head of the locking jackscrew is screwed into the locking gear, and the locking gear acts as a nut. The locking rack meshed...

Abstract

The invention discloses a mould locking device capable of bearing larger impact, which comprises a punch holder and a mould arranged in the punch holder. A locking top thread is arranged between the mould and the punch holder. A locking gear is screwed at the head of the locking top thread. The locking gear is engaged with a locking rack which is erected on a rack support through a support rod. The locking rack can rotate around the support rod. A limiting rod is screwed on the rack support. The mould locking device has simple structure and very good locking effect and is simple to replace the mould.

Description

[0001] technical field [0002] The invention relates to a mold locking device capable of withstanding relatively large impact. Background technique [0003] The material cutting system of the multi-station automatic cold heading forging machine sends the cut material directly to the first forming station. The first forming station is an upsetting forming station with a mold. After the upsetting is formed, the workpiece after the upsetting is pushed out of the mold through the push-out mechanism. When the mold locking screw is loose and the clamping force is not enough, the mold will move forward together with the material when it is pushed out, and the cutting knife will directly cut to the mold. Because the material hardness of the mold is very high, the cutting tool design If the material force cannot cut off the mold, the cutting system will be overloaded and damaged. [0004] At present, the method commonly used for the mold locking of multi-station automatic upsettin...
