The die casting machine is a machine for pressure casting and is generally divided into a hot pressing chamber and a cold pressing chamber; the pressure chamber structure and arrangement mode can be divided into a straight die casting machine and a horizontal die casting machine. The die casting machine hydraulically shoots molten metal into a die under the action of pressure to be cooled and molded, and after the die is opened, a solid metal casting can be obtained and is initially used for die casting types.

Example 1: as shown in fig. 1 to 4, a novel die adjusting structure mainly comprises a head plate 6, two plates 8, a tail plate 10 and a pull rod 9, wherein the pull rod 9 passes through the two plates 8 and the tail plate 10 and is connected with the head plate 6, a die is positioned between the head plate 6 and the two plates 8, and the distance between the head plate 6 and the two plates 8 can be adjusted according to the thickness a of the die. The pull rod 9 is provided with a die adjusting nut 1, and a die adjusting large gear ring 12 for adjusting the die adjusting nut 1 is arranged on one side of the tail plate 10. The die adjusting screw 1 is in threaded fit with the pull rod 9, namely the pull rod 9 is provided with a polish rod section and a threaded section so as to pass through the two plates 8 and the tail plate 10 and simultaneously be matched with the die adjusting screw 1. The pull rod 9 is in sliding fit with the tail plate 10 and the two plates 8 through guide sleeves, and is fixedly connected with the head plate 6 through screws or other fixing modes.
When the ultra-large die casting machine or the injection molding machine is used for die adjustment, the required die adjustment force is huge, the die adjustment screw 1 is convenient to lubricate in order to prevent the die adjustment screw 1 from being meshed with the pull rod 9 during die adjustment, the die adjustment screw 1 made of copper alloy materials is needed, and the cost of the die adjustment screw 1 made of copper materials is very high, so that the cost control is not facilitated.
In this embodiment, the load requirement of the die adjusting screw 1 during die adjustment is reduced, so that the die adjusting screw 1 made of cast iron material can also complete work, thereby reducing production cost. Specifically, in the mold adjusting mechanism in this embodiment, a bar oil cylinder 2, an auxiliary mold adjusting oil cylinder 11 and a mold adjusting motor 4 are assembled, the bar oil cylinder 2 connects the two plates 8 and the tail plate 10, the output end of the mold adjusting motor 4 is provided with motor teeth 3, and the motor teeth 3 are engaged with the large mold adjusting gear ring 12. The pumping cylinder 2 is installed above the two plates 8 and the tail plate 10, and the auxiliary die adjusting cylinder 11 is connected below the two plates 8 and the tail plate 10. When the thickness of the die is required to be adjusted, the pumping rod oil cylinder 2 and the auxiliary die adjusting oil cylinder 11 supply pressure together to provide hydraulic thrust with the magnitude close to the static friction force of the two plates 8 and the tail plate 10, and push the tail plate 10 together to overcome the die adjusting resistance, and simultaneously start the motor 4 to drive the die adjusting large gear ring 12 to rotate, so that the four die adjusting nuts 1 rotate to drive the tail plate 10 to move forwards or backwards, so as to accurately control the position of the tail plate 10, and accurately adjust the die thickness A. Compared with the mode of directly pushing the tail plate 10 by the die adjusting screw 1 in the traditional mode, the drawing bar oil cylinder 2 and the auxiliary die adjusting oil cylinder 11 in the embodiment can eliminate most of die adjusting resistance, so that the die adjusting force required by pushing the tail plate 10 by the die adjusting screw 1 is greatly reduced, the threaded matching load between the die adjusting screw 1 and the pull rod 9 is reduced, the die adjusting screw 1 is not engaged with cast iron materials, the service life of the die adjusting screw 1 made of cast iron materials is ensured, and the use cost of the auxiliary die adjusting oil cylinder 11 is far lower than the copper material cost of the die adjusting screw 1, so that the use cost is reduced. Meanwhile, the reduction of the die adjusting load also means that the power required by the die adjusting motor 4 can be greatly reduced, so that the die adjusting motor 4 with low power can be selected, the use cost is further reduced, and the reliability is improved.
In order to ensure the accuracy of the driving effect and the driving direction, the auxiliary die adjusting cylinder 11 may be installed at the bottom center of the tail plate 10, and the movement of the bar extracting cylinder 2 above the tail plate 10 may be balanced, and the bar extracting cylinder 2 and the auxiliary die adjusting cylinder 11 may jointly push the tail plate 10 and the two plates 8 to move.

In this embodiment, when a thin or thick die is required to be adjusted, the pumping rod cylinder 2 and the auxiliary die adjusting cylinder 11 supply pressure together to provide hydraulic thrust with a magnitude close to the static friction force of the two plates 8 and the tail plate 10, so as to push the tail plate 10 together to overcome die adjusting resistance, and meanwhile, the motor 4 is started to drive the die adjusting large gear ring 12 to rotate, so that the four die adjusting nuts 1 rotate to drive the tail plate 10 to move forwards or backwards, and the position of the tail plate 10 is precisely controlled, so that the die thickness A is precisely adjusted. The overall structure is approximately unchanged (namely the reliability is unchanged), and the cost is reduced under the condition that only the auxiliary die adjusting oil cylinder is added.
Example 2: the present embodiment is different from embodiment 1 in that: in the novel die adjusting structure in the embodiment, the drawing bar oil cylinder 2 is only arranged above the two plates 8 and the tail plate 10, and the auxiliary die adjusting oil cylinder 11 is not arranged, so that the die adjusting effect can be realized.
