Problems solved by technology
[0002] At present, the mold guiding device of the prior art includes a guide post and a guide hole, but since the guide post and the guide hole are all made of steel or iron, when the guide post slides in the guide hole, the distance between the guide post and the guide hole It is prone to stagnation between the guide post and the guide hole, which will lead to serious wear of the guide post or guide hole, which will lead to poor mold clamping accuracy and low product yield; at the same time, the guide post and guide hole are prone to seizure, which will easily lead to In the case of mold damage or cracking, resulting in production interruption or mold scrapping
Therefore, there is serious wear and tear in the mold guiding device of the prior art, and the problem of being easily seized

The invention discloses a mould guide device. The mould guide device comprises a guide hole formed in a mould body, wherein a copper sleeve is arranged in the guide hole. The mould guide device is characterized in that a ring-shaped bump is arranged on a position, close to the end surface, of the outer periphery of the top of the copper sleeve, wherein threads are arranged on the peripheral surface of the ring-shaped bump; the guide hole is detachably connected with the copper sleeve through the threads; a plurality of radial through holes are formed in the copper sleeve; and graphite is filled in the through holes. Compared with the prior art, the mould guide device has remarkable advantages and beneficial effects that the copper sleeve is more convenient to mount and dismount, the coppersleeve or a guide post is not liable to abrade, continuity and stability of mould production can be further improved, and the service life of a mould is further prolonged.
Description
technical field [0001] The invention belongs to the field of mold equipment, in particular to a mold guiding device. Background technique [0002] At present, the mold guiding device of the prior art includes a guide post and a guide hole, but since the guide post and the guide hole are all made of steel or iron, when the guide post slides in the guide hole, the distance between the guide post and the guide hole It is prone to stagnation between the guide post and the guide hole, which will lead to serious wear of the guide post or guide hole, which will lead to poor mold clamping accuracy and low product yield; at the same time, the guide post and guide hole are prone to seizure, which will easily lead to The situation where the mold is damaged or cracked, resulting in production interruption or mold scrapping. Therefore there is serious wear and tear in the mold guiding device of prior art, the problem that is easily seized to death. Contents of the invention [0003] ...
