Abstract

The invention discloses an auxiliary die adjusting system of a vertical type extrusion casting machine and relates to the technical field of casting machines. The auxiliary die adjusting system comprises a nitrogen gas cylinder and a tail board. Two sides of the tail board are respectively provided with one auxiliary die adjusting cylinder, piston rods of the auxiliary die adjusting cylinders are respectively connected with two sides of the tail board, each auxiliary die adjusting cylinder is divided into a front cavity and a rear cavity, the front cavities are communicated with a nitrogen gas cylinder pipe, the rear cavities are communicated with the atmosphere, and a high-pressure air valve is arranged on a pipe between the nitrogen gas cylinder and the front cavities. The auxiliary die adjusting system of the vertical type extrusion casting machine facilitates die adjustment, reduces abrasion of draglinks and threads of adjusting nuts and saves nitrogen gas.

Description

technical field

[0001] The invention relates to the technical field of casting machines, in particular to an auxiliary mold adjustment system for a vertical squeeze casting machine. Background technique

[0002] refer to figure 1 As shown, during the use of the vertical squeeze casting machine, it is often necessary to replace the mold (3 in the figure is a static mold, and 4 is a moving mold). Due to the difference in mold thickness, it is necessary to frequently adjust the tail plate 7 relative to the head Distance between plates 1.

[0003] The principle of mold adjustment is: the mold adjustment hydraulic motor 9 drives the mold adjustment large gear 11 to rotate, the large gear 11 drives the four mold adjustment intermediate gears 10 to rotate, and the four intermediate gears 10 drive the four adjustment nuts on the four Corinthian pillars 2 12 rotates, because the four adjusting nuts 12 and the tail plate 7 are relatively fixed in the axial direction, so the rotation...
