Outer guide post component for mold

Abstract

The invention discloses an outer guide post component for a mold. The outer guide post component comprises a body component and an auxiliary component; the body component comprises a lower die, a pedestal, a guide post, an end plate, a guide sleeve, an upper base and an upper die; the pedestal is detachably connected to the lower die and is positioned at the upper surface of the lower die; a steelball sleeve rolls in a steel ball groove formed in the outer sidewall of the guide post so that the friction force between the guide post and the inner surface of the guide sleeve is remarkably reduced, and thus the abrasion of the guide post and the guide sleeve is reduced; lubricating oil can flow into the steel ball sleeve by virtue of communication of an oil tank and the steel ball groove soas to maintain a steel inside the steel ball sleeve; the service life of the steel ball is prolonged; the problems that when the mold is assembled, the guide post does a reciprocating motion inside the guide sleeve to generate friction which results in reduction of the guidance precision of the guide post and the guide post loses a guidance function are solved; the guide post needs not to be replaced; and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of guide pillars, and in particular relates to an outer guide pillar assembly of a mold. Background technique [0002] The guide post is an important part in the mold. It is used in combination with the components in the mold to ensure that the mold can move and guide the mold stroke with precise positioning. [0003] At present, when the mold is clamped in the market, a certain impact force is usually generated, which is easy to deform the guide post of the mold, and during the reciprocating movement of the guide post in the guide sleeve, it is easy to cause friction between the guide post and the guide post. Sets cause wear and tear. [0004] At present, when the molds on the market are clamped, the reciprocating movement of the guide post in the guide sleeve will cause friction. Long-term use will cause the guide precision of the guide post to decrease, and then lose the guiding function. At this time, t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a mold outer guide post assembly to solve the problem that the guide post reciprocating in the guide sleeve will cause friction when the molds on the market are currently clamped in the above-mentioned background technology, and long-term use will cause the guide post to wear out. The guiding precision is reduced, and then the guiding effect is lost. At this time, only the guide post can be replaced, which increases the production cost.
