Description

Technical Field

[0001] This utility model relates to the field of mold-related technology, specifically a slider internal extraction structure. Background Technology

[0002] Injection molds are categorized into large-gate molds, small-gate molds, and hot runner molds. Large-gate molds are suitable for products requiring high injection speeds and large flow rates, such as thick-walled products and large injection molded products. Their design facilitates rapid filling of the mold cavity with plastic material, reducing resistance and pressure loss in the material flow channels and improving injection efficiency. Small-gate molds are suitable for products requiring high precision and high appearance quality, such as electronic product casings and optical lenses. They utilize slender injection runners, which help control the flow rate and filling pressure of the injection material, reducing defects such as air bubbles and short flows, ensuring product quality and appearance. Hot runner molds are an advanced form of injection mold. They use a hot runner system to control the flow and cooling of plastic material, enabling a more precise and uniform injection process. Hot runner molds can reduce or eliminate defects such as flow marks and weld lines in products, improving the appearance quality and mechanical properties. Regardless of the mold type, after product preparation, demolding from two or more directions is required depending on the complexity of the product.

[0003] A mold double-slider internal core-pulling structure disclosed in CN117301443A includes a front mold blank and a rear mold blank. A front mold shovel is provided on one side of the front mold blank, and an inclined guide post is installed on the front mold shovel. A hook-leg slider is slidably connected to the inclined guide post. This invention, through the cooperation of the inclined guide post, the hook-leg slider, the internal core-pulling slider, and the first and second slider inserts, enables the hook-leg slider to move during the mold opening process via the inclined guide post. The hook-leg slider, in turn, drives the first and second slider inserts to move. Finally, the internal core-pulling slider moves downward under the action of the hook-leg slider, thereby achieving disengagement. Finally, the product is ejected using an ejector pin to complete the production. This invention solves the problem of simple core-pulling structures in confined spaces, providing enterprises and product designers with more structural options, while achieving more efficient production, reducing defect rates, and improving product quality.

[0004] While existing technologies have achieved the function of internal core pulling, the sliding protrusion of the slider is difficult to assemble with the sliding groove of the tie rod due to the relatively small mold space. In order to solve the above technical problems, we propose an internal core pulling structure for the slider. Utility Model Content

[0005] The purpose of this utility model is to provide a slider internal extraction structure to solve the problem in the prior art where the mold space is relatively small and the sliding protrusion of the slider is inconvenient to assemble with the sliding groove of the pull rod.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slider inner-drawing structure, including a pull rod and a slider, wherein the pull rod is provided with a groove at one end of the slider, and the slider is provided with a sliding protrusion that cooperates with the groove of the pull rod at one end, the contact surfaces of the pull rod and the slider are both set as inclined surfaces, and one end of the sliding protrusion is set as a cutting surface.

[0007] Preferably, the angle between the cutting surface of the sliding protrusion and the outer end face of the sliding protrusion is 90°.

[0008] Preferably, the cross-sectional shape of the groove is T-shaped, and the cross-sectional shape of the sliding protrusion is T-shaped.

[0009] Preferably, the angle between the inclined surface of the slider and the side surface of the slider is 120°.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the contact surfaces of the pull rod and the slider are both set as inclined surfaces, and one end of the sliding protrusion is set as a cutting surface. The setting of the cutting surface makes it convenient to insert the sliding protrusion into the slide groove, improves the assembly efficiency, and does not affect the fit between the sliding protrusion and the slide groove.
