Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a mold for processing waterproof products. Background Technology

[0002] In the design of injection molds and related products, "skirt" typically refers to an edge structure resembling the hem of a skirt. This design is used in a variety of products, especially in components requiring sealing or waterproofing. In waterproof products, the skirt can be designed to fit tightly with the bottom cover or other components, such as... Figure 1 As shown, this is to prevent moisture penetration. In the injection molds used to produce waterproof products with skirts, the front and rear mold cores are parallel to each other, resulting in the skirt of the injection-molded product being arranged at an angle, as shown. Figure 3 As shown, this arrangement problem will increase the difficulty of subsequent demolding and make it difficult to guarantee the processing accuracy of the waterproof product.

[0003] Therefore, existing technologies have shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, such as the difficulty in demolding leading to poor product quality, and to provide a mold for processing waterproof products.

[0005] This utility model is implemented as follows: A mold for processing waterproof products includes a front mold blank, a front mold core fixed to the front mold blank, a rear mold blank, and a rear mold core fixed to the rear mold blank. The front mold core and the rear mold core cooperate to form a cavity of the product. The side of the front mold core forming the cavity is provided with a first inclined surface. An injection space is provided on the rear mold core at a position corresponding to the first inclined surface. The inner wall of the injection space is provided with a notch that can form a waterproof skirt of the product. A column is provided in the injection space to form a product ejection position. The upper end of the column corresponding to the first inclined surface is provided with a second inclined surface, and both the column and the injection space are vertically arranged.

[0006] Furthermore, the front mold core has a protrusion at one end facing the rear mold core, and at least one first inclined surface is provided on both sides of the protrusion. The rear mold core has a groove adapted to the protrusion.

[0007] Furthermore, the rear mold core has slides on both sides, and the side of the slide closest to the rear mold core is part of the injection space. The side of the slide closest to the rear mold core is parallel to the column.

[0008] Furthermore, the upper mold blank is equipped with a shovel and an inclined guide post that can drive the movement of the slide.

[0009] This utility model provides a mold for processing waterproof products. The column and injection space are both vertically arranged. When the upper mold core and the lower mold core are combined for injection molding, the first inclined surface, the column and the injection space are combined to form the product cavity. After injection molding, the product is arranged in a vertical structure to replace the existing inclined arrangement, which greatly reduces the difficulty of subsequent demolding. This helps to improve the processing accuracy and waterproof performance of the product. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figures 1-6 This utility model discloses a mold for processing waterproof functional products. The waterproof functional product is used to combine with a bottom cover to achieve the waterproof effect of the combined component. The waterproof functional product includes an inclined surface mating surface, such as... Figure 2 As shown, a connector is provided on one side of the surface mating with the exterior, the skirt of the waterproof product is provided around the periphery of the connector, and the connector has a groove for removing glue.

[0021] The mold for processing the aforementioned waterproof products specifically includes a front mold blank 1, a front mold core 2 fixed to the front mold blank 1, a rear mold blank 3, and a rear mold core 4 fixed to the rear mold blank 3. The front mold blank 1 and the rear mold blank 3 can open and close to each other. When the front mold blank 1 and the rear mold blank 3 are combined, the front mold core 2 and the rear mold core 4 are brought closer together and the product injection molding operation begins. Conversely, when the two are separated, the injection molding ends.

[0022] The front mold core 2 and the rear mold core 4 cooperate to form a product cavity. Specifically, the front mold core 2 has a first inclined surface 22 on the side forming the cavity. The end of the front mold core 2 facing the rear mold core 4 has a protrusion 21, and at least one of the first inclined surfaces 22 is provided on both sides of the protrusion 21. The rear mold core 4 has a groove 44 that adapts to the protrusion 21. When injection molding is required, the front mold core 2 and the rear mold core 4 are combined, i.e., the protrusion 21 extends into the groove 44, and injection molding can begin.

[0023] The rear mold core 4 is provided with an injection space 41 at the position of the first inclined surface 22. The inner wall of the injection space 41 is provided with a notch that can form a waterproof skirt for the product. The injection space 41 is provided with a column 42 that forms a sprue for the product. The upper end of the column 42 is provided with a second inclined surface 43 corresponding to the first inclined surface 22. That is, the first inclined surface 22 and the second inclined surface 43 cooperate with each other to form the appearance mating surface of the waterproof product. The column 42 and the inner wall of the injection space 41 cooperate with each other to form the sprue for the waterproof product. Both the column 42 and the injection space 41 are vertically arranged to ensure that the waterproof skirt of the product formed in the injection space 41 is horizontal and the entire product is arranged in a vertical direction.

[0024] In injection molds, product ejection requires the cooperation of slide 5, shovel 6, and inclined guide post 7. The operational principle of ejection using this cooperation is well-known in existing technologies, and will not be specifically elaborated upon in this embodiment. Specifically, slides 5 are provided on both sides of the rear mold core 4. The side of the slide 5 closest to the rear mold core 4 is part of the injection space 41, meaning the notch forming the skirt is also formed on the side of the slide 5 closest to the rear mold core 4. The upper mold blank is provided with the shovel 6 and the inclined guide post 7, and the side of the slide 5 closest to the rear mold core 4 is parallel to the post 42. After injection molding, the front mold core 2 and the rear mold core 4 separate, that is, the protrusion 21 gradually extends out of the groove 44. At this time, the inclined guide post 7 also gradually separates from the slide 5. During the separation process, as the inclined guide post 7 rises, the slide 5 will slowly move horizontally away from the column 42. Since the side of the slide 5 close to the rear mold core 4 is parallel to the column 42, the slide 5 can quickly separate the notch and the skirt of the waterproof product at the same time during the movement. Moreover, the entire waterproof product is vertically arranged, and the skirt of the product has no inclination. Subsequently, the shovel 6 only needs to drive the vertical lifting of the waterproof product to lift the product without damaging the skirt, which greatly reduces the difficulty of demolding. And ensuring the integrity of the skirt can ensure the waterproof function of the entire waterproof product.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
