Description
Technical Field
The utility model relates to a mould especially relates to an annular rubber bush cut-out press.
Background
If the annular rubber sealing bush needs to be provided with a through hole on the side wall, the prior technical scheme basically adopts a one-step vulcanization molding scheme, and the scheme has the defects that a hole-molding mold core needs to be fixed on an outer mold of a mold, so that the machining difficulty is greatly increased, and the manufacturing cost of the mold is increased; on the other hand, when the die is installed and assembled in the using process, the core on the outer die is easy to collide with the middle die, the service life of the die can be shortened to a certain extent, and great working difficulty is brought to the subsequent deburring process.
Disclosure of Invention
An object of the utility model is to provide an annular rubber bush cut-out press to solve the problem of mentioning among the above-mentioned background art.
Annular rubber bush punching die, including the base, an organic whole is connected with the riser on the base, has set firmly the cross axle on the riser, and the top of cross axle is provided with fan-shaped area hole mould, has seted up the shrinkage pool on the fan-shaped area hole mould.
Preferably, the punching device further comprises a punch, the punch consists of a punch rod and a punch head, the punch rod and the punch head are integrally formed, and the concave hole is formed by pressing and cutting the punch.
Preferably, the punch is made of hard alloy steel material, and a chromium coating is further arranged on the outer surface of the punch.
Preferably, the vertical plate is further provided with a sliding groove, a sliding block is arranged in the sliding groove in a sliding mode, the fan-shaped hole die is integrally connected with a support, and the support is in threaded connection with the sliding block.
Compared with the prior art, the utility model discloses following beneficial effect has: the problem of the easy loss of mould has been solved to this scheme, has greatly reduced the work degree of difficulty of burring process, and the round hole characteristic uniformity of goods is high, has guaranteed the uniformity of goods outward appearance with the size, has improved work efficiency and quality, has shortened product production processing cycle, and the punching die dismouting is simple, the use is convenient, to the adaptability of different specification bushes strong, provides a comparatively practical production facility for punching a hole of annular rubber bush.
