Description

Slider device of loosing core with oblique guide pillar

Technical Field

The utility model belongs to the technical field of slider core-pulling equipment, and particularly relates to a slider core-pulling device with an inclined guide pillar.

Background

The inclined guide post lateral parting core-pulling mechanism mainly depends on the mold opening force on an injection molding machine and realizes parting and core-pulling by transmitting the mold opening force to parts. That is to say, the inclined guide post and the slide block generate relative motion when the mold is opened, the slide block moves along the mold opening direction on one side under the action of the inclined guide post, and the other side moves laterally, wherein the lateral movement enables the lateral molding part of the mold to be separated from the concave-convex core-pulling structure on the inner side and the outer side of the plastic part. The core pulling mechanism on the outer side of the inclined guide post and the slide block at the movable die is the most common core pulling mechanism, the core pulling action is completed instantly, and the core pulling mechanism is suitable for the environment with higher automatic injection molding efficiency. The inclined guide post and slide block core pulling mechanism has the characteristics of compact structure, safe and reliable action, convenient processing and larger side core pulling distance, thereby being the most commonly used side parting and core pulling mechanism of the current injection mold. However, in the actual use process, the guiding stability is poor, and the die sinking is easy to deviate. Besides, the conventional inclined guide pillar and the slider have poor matching effect, so that the production efficiency is low.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a novel oblique guide post slider side core-pulling injection mold [201520803586.5], which comprises a movable mold assembly and a fixed mold assembly, wherein the movable mold assembly comprises a support plate, a movable mold plate is arranged above the support plate, a stripper plate is arranged above the movable mold plate, a male mold is arranged in the center of the support plate, the male mold passes through the movable mold plate and the stripper plate, and the support plate is provided with an oblique guide post; the fixed die assembly comprises a fixed die base plate, a sprue bush is arranged in the center of the fixed die base plate, a cavity insert corresponding to the male die is mounted on the lower surface of the fixed die base plate, a fixed die plate is sleeved outside the cavity insert, a side core slide block is arranged in the fixed die plate, and an inclined guide hole corresponding to the inclined guide pillar is formed in the side core slide block; the bearing plate is provided with a guide post and a push rod for pushing the pushing plate.

Above-mentioned scheme has solved the relatively poor problem of oblique guide pillar and slider cooperation effect to a certain extent, but this scheme still has a great deal of not enough, for example the relatively poor scheduling problem of direction stability.
