Description
Technical Field
The invention relates to the technical field of dies, in particular to a novel die ejection type sliding block device suitable for a sliding block with a high-temperature large stroke.
Background
In the mould trade, there is a mould with slider, especially the mould that has the big stroke slider of high temperature, all promote the motion of slider, and the slider has certain inclination, open through certain inclination, the inclination of this slider is 6-8 degrees usually, generally not more than 10 degrees, the biggest limit is 15 degrees, it will die to block to exceed this angle slider, the unable normal action of mould, to the big stroke slider that inclination has exceeded 15 degrees among the prior art, all adopt the hydro-cylinder to drive the slider motion, thereby solve slider inclination's problem, although the design is fairly simple, but there is inherent not enough, if: (1) in a high-temperature production die, an oil cylinder is easy to damage and oil leakage is easy to occur; (2) the oil cylinder exceeds the appearance of the mould and is easy to collide and bump, so that the mould lifting efficiency is low and potential safety hazards exist; (3) the molds with the oil cylinders in batches are difficult to manage, are not easy to place and occupy large space.
Disclosure of Invention
In order to solve the defects and problems of a high-temperature large-stroke sliding block die in the prior art, a novel die ejection type sliding block device is provided.
The technical scheme adopted by the invention for solving the technical problem is as follows: the novel mold ejection type sliding block device comprises an upper template, wherein a guide block is fixed on the upper template through a screw fastener, the guide block is in an inclined triangle shape, graphite columns are embedded on the inclined surface of the guide block, the graphite columns are uniformly distributed on the inclined surface of the guide block, the inclined surface of the guide block is matched with a sliding block, and the sliding block is sleeved on a mandrel; the sliding block is propped by a mandril, and a bearing roller is arranged at the matching position between the sliding block and the mandril; the inclination angle A of the sliding block is less than or equal to 35 degrees.
The invention has the beneficial effects that: compared with the prior art, when the novel mold ejection type sliding block device is ejected, the ejector rod and the bearing roller drive the sliding block to move upwards along the inclined plane direction of the guide block, the contact surface of the guide block and the sliding block is blindly inlaid with the graphite column, and the graphite column has corrosion resistance and very good lubricity, because the stroke angle of the slide block is large, the friction force with the guide block is also amplified, the friction force can be effectively reduced through the graphite column, the graphite column is embedded in the contact surface in a blind way, so that the friction force can be effectively reduced, the pulling risk of the sliding block and the guide block is greatly reduced, the melting point of the graphite column is 3850 +/-50 ℃, the boiling point of the graphite column is 4250 ℃, the graphite column is very high-temperature resistant, the thermal expansion coefficient is small, the use of the high-mold-temperature mold is completely unaffected, the slide block with the highest inclination angle of 35 degrees is adopted to replace the oil cylinder, the problem of oil leakage of the oil cylinder at high temperature is solved, and the trouble caused by the exposure of the oil cylinder is solved.
Drawings
