Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a buckle demoulding mechanism for preventing an injection molded workpiece from being deformed. Background Art

[0002] A snap-on demoulding mechanism that prevents deformation of injection molded workpieces is a specially designed mold demoulding system that ensures that the plastic workpiece can be smoothly ejected from the mold during the injection molding process through precise snap-on design and mechanical operation, while effectively controlling the force applied to the workpiece during the demoulding process to reduce the risk of deformation. This mechanism design takes into account the needs of different workpiece shapes and sizes, aims to improve production efficiency and product quality, and is one of the important innovations in modern injection mold technology.

[0003] In the prior art, most snap-on demoulding mechanisms usually use a relatively tight snap-on structure, which causes the workpiece to be clamped too tightly during the shaping process, making it difficult to demould, thereby requiring forced demoulding. The forced demoulding process can easily cause the molded workpiece to deform, rendering the workpiece unusable.

[0004] With regard to the structure in the prior art, a snap-on structure that is too tight is not only inconvenient for demolding the workpiece, but also easily causes the shaped workpiece to deform during the demolding process, thereby rendering the workpiece unusable, which not only increases costs but also affects work efficiency and causes inconvenience to the injection molding work. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a snap-on demoulding mechanism for preventing deformation of an injection molded workpiece, aiming to improve the effect of demoulding the workpiece in the prior art to facilitate demoulding and prevent deformation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snap-on demolding mechanism for preventing deformation of an injection molded workpiece, comprising a slider housing, a sliding sleeve fixedly connected to the interior of the slider housing, a slider insert fixedly connected to the outer wall of the sliding sleeve, a clamp fixedly connected to the outer wall of the slider insert, a mold head slidably connected to the outer wall of the clamp, a mold body fixedly connected to the outer wall of the mold head, a clamping groove is opened inside the slider housing, a snap-on assembly is arranged inside the slider housing, and the snap-on assembly is used to facilitate demolding of the workpiece.

[0007] Furthermore, the buckle assembly includes a front mold insert, which is slidably connected to the inside of the slider housing, the front mold insert slides inside the slot, and the inside of the slider housing is slidably connected to a rear mold core insert.

[0008] Furthermore, a first groove is provided inside the front mold insert, and a second groove is provided inside the rear mold core-pulling insert.

[0009] Furthermore, the first groove is arranged at the lower end of the front mold insert, and the second groove is arranged at the upper end of the rear mold core insert.

[0010] Furthermore, the outer wall of the rear mold core-pulling insert is slidably connected to a base, and a limiting groove is provided inside the base.

[0011] Furthermore, a clamping strip is fixedly connected to the outer wall of the rear mold core-pulling insert, and the clamping strip is slidably connected to the inside of the limiting groove.

[0012] Furthermore, the die head is arranged at one end of the die body, and the die head is arranged in an arc shape.

[0013] Furthermore, the clamping grooves are arranged at the upper and lower ends of the slider housing, and a circular hole is opened inside the slider housing.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the front mold insert is slid upward to make it slide out from the interior of the slider housing, and then the rear mold core insert is moved downward. When both the rear mold core insert and the front mold insert slide out from the interior of the slider housing, the slider housing is moved outward to make the slider housing drive the sliding sleeve and the slider insert to slide out from between the mold heads, thereby facilitating demoulding and preventing deformation of the workpiece caused by forced demoulding.

[0016] 2. In the utility model, the card grooves at the upper and lower ends of the slider shell are convenient for the front mold insert and the rear mold core-pulling insert to slide and form a buckle. The rear mold core-pulling insert passes through the base from bottom to top, so that the card strip is stuck in the inside of the limit groove. The base is laid flat on the operating table and fixed with a nut, which can prevent the rear mold core-pulling insert from falling off, plays the role of auxiliary support, and has the effect of assisting shaping.
