Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold slider assembly for achieving lateral core pulling and ejection. Background Technology

[0002] Injection molding is a process in which molten material is injected into a mold, allowing it to solidify and harden into a finished product. Some injection-molded products require core-pulling. Current injection molding processes typically achieve this by using a slider mechanism along the mold opening direction for lateral core-pulling. Specifically, a slanted lever drives the slider seat and insert laterally, while guide blocks, wear plates, and pressure strips ensure the stability and consistent movement of the slider structure to achieve the core-pulling operation.

[0003] The slider structure can only achieve core-pulling action. That is, after the mold completes the lateral core-pulling operation during injection molding, the injection molded product still needs to be ejected by the ejection system (such as ejector pins) to complete the injection molding process. However, relying on the ejection system to eject the injection molded product leaves parting lines on the product surface. For some plastic injection molded products, ejection marks (such as ejector pin marks) are not allowed on the surface of the product in the mold opening direction. Furthermore, the injection mold is required to completely detach the product from the mold during the core-pulling process. Therefore, existing injection molding dies have limitations in certain applications. Utility Model Content

[0004] This invention was developed to solve the above-mentioned problems, and its purpose is to provide a slider assembly for injection molds that enables lateral core pulling and ejection.

[0005] This utility model provides a slider assembly for injection molds that enables lateral core pulling and ejection. It includes: a base, a lever, a slider seat, a slider, a slider core, and an ejector block.

[0006] The lever is inclined and mounted on the base. A slotted hole is provided on the slider seat, allowing it to be fitted onto the lever. The slider is slidably mounted on the slider seat and has an angled sliding hole, allowing it to slide along the lever while mounted. The slider core is located on one side wall of the slider. An ejector block is mounted on the slider seat, with at least a portion protruding above the slider seat. The portion of the ejector block above the slider seat has a through hole for the slider core to pass through.

[0007] The sliding hole is located directly above the waist-shaped hole.

[0008] The injection mold slider assembly for side core pulling and ejection provided by this utility model also has the following features: a slide rail is provided on the top wall of the slider seat along its center line, and a slide groove is provided on the bottom wall of the slider at the position corresponding to the slide rail, so that the slider can be slidably disposed on the slider seat.

[0009] Furthermore, the upper opening of the waist-shaped hole is located on the top wall of the slide rail, and the lower opening of the sliding hole is located on the bottom of the slide groove.

[0010] The injection mold slider assembly for side core pulling provided by this utility model also has the following features: the ejector block is located in front of the slider, so that the slider can move closer to or away from the ejector block after sliding, and the slider core is located on the side wall of the slider facing the ejector block.

[0019] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0020] Example

[0021] Figure 1 This is a schematic diagram of the structure of this utility model when it is not in the ejection and core-pulling state. Figure 2 This is a top view of the present invention when it is not in the ejected / core-pulling state. Figure 3 This is a schematic diagram of the structure of this utility model in the ejection and core-pulling state. Figure 4This is a top view of the present invention in the ejected core-pulling state.

[0022] like Figures 1 to 4 As shown, this embodiment provides a slider assembly for an injection mold that enables lateral core pulling and ejection, including: a base 10, a lever 20, a slider seat 30, a slider 40, an ejector block 50, and a slider core 60.

[0023] like Figures 1 to 4 As shown, the lever 20 is inclined on the base 10. In this embodiment, the lever 20 is preferably a round rod.

[0024] like Figures 1 to 4 As shown, the slider seat 30 has an oblong hole 31, allowing the slider seat 30 to be fitted onto the lever 20. In this embodiment, the slider seat 30 is preferably plate-shaped, with a slide rail 32 on its top wall along its center line. The width of the oblong hole 31 is not less than the diameter of the lever 20.

[0025] like Figures 1 to 4 As shown, the slider 40 is slidably mounted on the slider base 30, and the slider 40 has an oblique sliding hole 41, allowing the slider 40 to be fitted onto the lever 20 and slide along the lever 20. In this embodiment, the slider 40 is preferably plate-shaped, and its bottom wall has a groove 42 at a position corresponding to the slide rail 32, allowing the slider 40 to be slidably mounted on the slider base 30. The sliding hole 41 is located directly above the oblong hole 31, and the diameter of the sliding hole 41 is not less than the diameter of the lever 20.

[0026] like Figures 1 to 4 As shown, the ejector block 50 is disposed on the slider seat 30, and at least a portion of it is higher than the slider seat 30. The portion of the ejector block 50 that is higher than the slider seat 30 is provided with a through hole for the slider core 60 to pass through. In this embodiment, the ejector block 50 is disposed in front of the slider 40, so that the slider 40 can move closer to or further away from the ejector block 50 after sliding.

[0027] like Figures 1 to 4 As shown, the slider core 60 is disposed on one side wall of the slider 40. In this embodiment, specifically, the slider core 60 is disposed on the side wall of the slider 40 facing the ejector block 50. Preferably, the slider core 60 is made of stainless steel M340, and its heat treatment hardness is HRC58-60.

[0028] In this embodiment, the lever 20, slider seat 30, slider 40, and ejector block 50 are all made of 1.2767 material. Their heat treatment hardness is HRC58-60, and combined with DLC coating treatment, oil-free, long-term continuous production is achieved.

[0029] When performing a core-pulling and ejection operation using this invention, the ejection system of the injection mold will eject the slider seat 30 and its slider 40, as described in this application. Specifically, the slider 40 moves upward along the lever 20 while simultaneously sliding on the slider seat 30, thereby moving the slider core 60 and the injection-molded product on it, thus completing the core-pulling operation. Then, as the slider 40 continues to move, the injection-molded product will press against the ejector block 50, causing the injection-molded product to be ejected from the slider core 60, completing the demolding operation.

[0030] The role and effect of the embodiments

[0031] The injection mold slider assembly for side core pulling and ejection involved in this utility model can perform side ejection and side core pulling operations simultaneously, so no ejection marks will be produced on the surface of the injection molded product, and the cycle time of the injection molding process can also be saved. Therefore, this utility model has better practicality and applicability.

[0032] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
