an injection mold

Abstract

The invention discloses an injection mold and a side pulling limiting mechanism thereof. According to the technical scheme, the injection mold is characterized by comprising a first installing table, an inclined guiding column connected to the first installing table, a second installing table and a side mold core slider; the side mold core slider is provided with an inclined guiding hole and a forming end; the first installing table and the second installing table can be separated from or get close to each other; the inclined guiding column and the inclined guiding hole are matched in an inserted connection manner so as to drive the side mold core slider to slide back and forth; a main limiting part is further included, and comprises a limiting clamp assembly installed on the second installing table; the limiting clamp assembly comprises at least two limiting clamp pieces and a torsion spring; a clamp gap exists between every two adjacent limiting clamp pieces; the side mold core slider is provided with a limiting block; the side pulling limiting mechanism is arranged in the mold; the power of an auxiliary limiting assembly comes from the action generated by the limiting clamp pieces; the limiting end in the auxiliary limiting assembly can abut against a sliding block, and the limiting end and the sliding block are mutually matched, the sliding stability of the side mold core slider is substantially improved, and the overall service life of the mold is prolonged.

Description

technical field [0001] The invention relates to an injection molding tool for plastic products, in particular to an injection mold. Background technique [0002] Existing injection molding molds for plastic products, such as the Chinese invention patent CN105150468A with the notification number CN105150468A, have side-pulling injection molds, which mainly include a fixed mold and a moving mold inside. For the molding cavity of the product, for some plastic products with mounting holes on the outer wall, a side core-pulling mechanism will be installed at the corresponding mounting hole. The side core-pulling mechanism can refer to the attached figure 1 , the side core-pulling mechanism includes a side core slider, the end of the side core slider is used to form a mounting hole, and an oblique guide hole is also set in the side core slider, and an oblique guide post is also provided, and the oblique guide post is inserted into the into the inclined guide hole, and can be used...

AI Technical Summary

Problems solved by technology

[0003] To realize the sliding action of the side core slider, a sliding groove is usually provided on the surface of the corresponding movable mold, and the side core is slidably connected in the sliding groove. Since the height of the entire side core block is high, if only relying on The sliding groove limit slip effect, the sliding stability of the entire side core slider is not strong, which will affect the actual service life of the entire side core pulling mechanism
