Abstract
The invention provides a disc type hot-pressing automatic cleaning die, wherein a die cavity is arranged in the middle of a side die, a steel back covers the top of the side die at the die cavity, a core die is arranged in the die cavity, the core die is T-shaped, and a boss is arranged at the top of the core die; has the advantages that: the flash between the core mould and the mould cavity is not remained, the phenomenon of mould cavity drawing is not generated, the smooth production is ensured, the service life of the mould is prolonged, the ultrasonic cleaning is not needed, the energy is saved, the environment is protected, and the time and the labor are saved.
Description
Technical Field
The invention relates to the field of disc brake pads, in particular to a disc type hot-pressing automatic cleaning die.
Background
When the mold is used for a long time, the core mold and the inner wall of the mold cavity naturally generate flash edges, and the flash materials filled into the gap are extruded into the gap more and more along with the continuous increase of the hot pressing times, so that the core mold and the mold cavity are locked mutually, the mold cavity is slightly damaged by pulling, and the core mold and the mold cavity are directly locked to cause the failure of work. The method for reducing the locking of the die cavity can be used, namely, the die is disassembled after each hot pressing is finished, and the extrusion flash left on the inner wall of the die cavity by each hot pressing is cleaned by an ultrasonic cleaning machine, but the process has the advantages of large investment, low efficiency and no environmental protection.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provide a disc type hot-pressing automatic cleaning die.
The new technical scheme of the invention is as follows: the utility model provides a disk hot pressing self-cleaning's mould, includes side forms, mandrel and steel backing, side forms middle part be equipped with the die cavity, die cavity department side forms top cover have the steel backing, the die cavity in be equipped with the mandrel, the mandrel be the T type, the mandrel top is the boss.
The boss at the top of the core mold is 25mm thick.
The distance between the outer wall of the boss and the inner wall of the die cavity is 0.2 mm.
The outer diameter of the lower part of the core mould is smaller than that of the boss at the top of the core mould.
The outer diameter of the lower part of the core mould is 0.8-1.2mm smaller than that of the lug boss at the top of the core mould.
The distance between the outer wall of the lower part of the core mold and the inner wall of the mold cavity is 1.0-1.4 mm.
The invention has the beneficial effects that: the flash between the core mould and the mould cavity is not remained, the phenomenon of mould cavity drawing is not generated, the smooth production is ensured, the service life of the mould is prolonged, the ultrasonic cleaning is not needed, the energy is saved, the environment is protected, and the time and the labor are saved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Wherein: 1. side die 101, die cavity 2, steel backing 3, core die 301 and boss.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
The utility model provides a disk hot pressing self-cleaning's mould, includes side forms 1, mandrel 3 and steel backing 2, 1 middle part of side forms be equipped with die cavity 101, die cavity 101 department 1 top of side forms cover and have steel backing 2, die cavity 101 in be equipped with mandrel 3, mandrel 3 be the T type, 3 tops of mandrel are boss 301.
The boss 301 on the top of the core mold 3 is 25mm thick.
The distance between the outer wall of the boss 301 and the inner wall of the die cavity 101 is 0.2 mm.
The outer diameter of the lower part of the core mould 3 is smaller than that of the boss 301 at the top of the core mould 3.
The outer diameter of the lower part of the core mould 3 is 0.8-1.2mm smaller than that of a boss 301 at the top of the core mould 3.
The distance between the outer wall of the lower part of the core mold 3 and the inner wall of the mold cavity 101 is 1.0-1.4 mm.
A hot pressing material is poured into a die cavity 101 between the top of a core film and a steel backing 2, the steel backing 2 is covered on the top of the die cavity 101, a hot press is used for simultaneously applying working pressure to the steel backing 2 and a core die 3 to promote product forming, the product is taken out of the die cavity 101 after being formed, then the hot press drives the core die 3 to move up and down in the die cavity 101, a scraper-type surface is formed on the periphery of a boss 301 on the top of the core die 3, overflowing generated in the die cavity 101 at any time is removed, the overflowing freely falls down through a space of 1.0-1.4mm below the core die 3, and the overflowing between the core die 3 and the die cavity 101 is not remained, so that the work is always kept in a smooth state.
