Plastic mold with guide lubricating structure

Abstract

The invention discloses a plastic mold with a guide lubricating structure, and relates to the technical field of molds. The plastic mold with the guide lubricating structure comprises a main body module; the main body module comprises a rear mold, a front mold and a base plate; the front mold is provided with a guide module; the guide module comprises a guide block and a guide rod; the guide module further comprises a rolling groove and a rolling ball; the guide block and the guide rod on the guide module move in a rolling mode through the rolling ball; and the guide module further comprises a limiting bag capable of limiting the rolling ball from impacting. According to the plastic mold with the guide lubricating structure, when the guide rod moves in a square guide opening in the guide block, through elastic limitation of the limiting bag, the rolling ball has a sufficient rolling space during rolling, meanwhile, the rolling ball is limited to collide and roll disorderly in the rolling groove, thus protection on the rolling ball is improved, and the situation that the friction coefficient is increased in the moving process of the guide rod due to the fact that the rolling ball is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a plastic mold with a guide lubrication structure. Background technique [0002] When using plastic molds to produce products, it is set up to ensure that the front mold and the rear mold can be accurately centered when the mold is closed. Generally, guide posts and guide sleeves are set in the mold, in order to reduce the relative wear of the guide posts and guide sleeves. The quantity needs to be lubricated all the time during its use. The usual method is to set up an oil groove on the guide post body or guide post sleeve, and manually apply and add grease or lubricating oil. However, this method is inconvenient to operate , additional labor hours are required, the amount of lubricating oil and grease used is large, the maintenance cost is high, the personnel work is negligent or not careful, it is easy to lubricate unevenly, and the amount of local wear is too large; [0003] C...

Problems solved by technology

[0005] Secondly, under the premise that there is a rolling space after the ball is blocked, it does not necessarily roll directly, and there is still a certain sliding phenomenon;

[0006] In combination with the above, although the installation of balls can reduce a certain amount of friction damage, there will be situations in which friction damage will be increased due to damage to the balls during the operation. Therefore, we propose a plastic mold with a guiding lubrication structure
