Lengthening device for tie bar guide hole of movable template of die casting machine

Abstract

The invention relates to a lengthening device for a tie bar guide hole of a movable template of a die casting machine. The lengthening device is characterized in that a left guide copper sleeve is mounted in a left end hole of the movable template; the excircle surface of the left guide copper sleeve is in transition fit with the inner hole surface of the movable template; a right guide seat is mounted in a right end hole of the movable template; a right guide copper sleeve is mounted in a hole of the right guide seat; the excircle surface of the right guide seat is in transition fit with the inner hole surface of the movable template; the inner hole surface of the right guide seat is in transition fit with the excircle surface of the right guide copper sleeve; a tie bar is matched with the inner hole surface of the left guide copper sleeve and the inner hole surface of the right guide copper sleeve; a first lubricating oil channel is formed in the movable template; the first lubricating oil channel communicates with an oil storage tank on the left guide copper sleeve; a second lubricating oil channel is formed in the right guide seat; and the second lubricating oil channel communicates with an oil storage tank on the right guide copper sleeve. According to the lengthening device, the guide seat is mounted at one end of the tie bar guide hole of the movable template, the guide length is lengthened, stability and repeated accuracy of locked mold opening are improved, oil is injected into the lubricating oil channels, and the tie bar and the guide copper sleeves are well lubricated.

Description

technical field [0001] The invention relates to a device for extending the guide hole of a die-casting mobile formwork Golin column. Background technique [0002] At present, during the use of the die-casting machine, the mold fit is mainly guaranteed by the movement of the movable template. In the current existing technology, the guide hole of the die-casting motorized template is provided with a guide copper in the guide hole of the Gelin column. Through the self-lubrication of the guide copper, the brother Lin Zhu achieves a better rotation effect, but due to the limited lubrication performance of the guide copper, the guide hole cannot be set too long, and the length is generally short. When the guide hole is short, the repeatability of each mold opening and clamping action is not high. The product difference during production is large, which affects the pass rate and output of production. [0003] The guide copper is directly installed on the movable template, and the ...

[0002] At present, during the use of the die-casting machine, the mold coordination is mainly guaranteed by the movement of the movable template. In the current existing technology, the guide hole of the die-casting motorized template is provided with a guide copper in the guide hole of the Gelin column. Through the self-lubrication of the guide copper, the brother Lin Zhu achieves a better rotation effect, but due to the limited lubrication performance of the guide copper, the guide hole cannot be set too long, and the length is generally short. When the guide hole is short, the repeatability of each mold opening and clamping action is not high. The product difference during production is large, which affects the pass rate and output of production

[0003] The guide copper is directly installed on the movable template, and the guide length is relatively short. To obtain a longer guide length, the structure of the movable template needs to be lengthened, which increases the cost
