Description

Technical Field

[0001] This utility model specifically relates to a novel double-layer injection mold. Background Technology

[0002] With the rapid changes in the market, traditional double-layer molds, due to single-sided injection, such as Figure 4 As shown, the flow rate of the rubber material in the two cavities is achieved by using different injection nozzle diameters to ensure a consistent injection rate. In actual production, it is difficult to ensure that the flow rate of each layer is consistent, resulting in poor uniformity of injection in the upper and lower double-layer plates, which affects the product vulcanization time and the product quality qualification rate. Therefore, we propose a new type of Hafur double-layer injection mold. Utility Model Content

[0003] The purpose of this invention is to provide a novel double-layer injection mold for hafnium to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel double-layer injection mold, comprising:

[0005] Upload template;

[0006] The hafn component is disposed on the lower surface of the upper template;

[0007] The template is placed below the Hafu component;

[0008] The Hafu component has molding cavities on both its upper and lower surfaces, an injection port on its inner side, the upper end of the injection port penetrating the upper surface of the Hafu component, and a flow channel communicating with the inner side of the molding cavity at the lower end of the injection port.

[0009] Preferably, the outer wall of the hafur component is fixed with a middle mold lifting frame for adjusting its position.

[0010] Preferably, the upper surface of the upper template is provided with a flow channel plate, and the flow channel plate has a connection port for cooperating with an external injection molding machine.

[0011] Preferably, guide blocks are provided at both ends of the upper surface of the Hafu component, and guide grooves corresponding to the guide blocks are provided on the lower surface of the upper template.

[0012] Preferably, multiple molding cavities are evenly distributed along the long side of the Hafur component.

[0013] Preferably, the lower surface of the upper template has a first mold cavity corresponding to the forming mold cavity, and the lower template has a second mold cavity corresponding to another forming mold cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a hafnium assembly, a molding cavity, runners, and injection ports. This allows for easy integration with upper and lower mold plates to form a double-layer cavity into which the resin is poured. This avoids the problems of traditional injection molds where, due to single-sided injection, it's difficult to ensure both layers are filled simultaneously, affecting vulcanization time. This device uses a hafnium assembly, placing the runners at the hafnium parting line and ensuring symmetrical runner openings for both layers, guaranteeing a uniform and consistent injection effect. This effectively increases the product qualification rate of the mold and reduces production costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a novel double-layer injection mold for HAF, comprising:

[0023] Template 2;

[0024] Hafu component 3 is disposed on the lower surface of the upper template 2;

[0025] The lower template 5 is placed below component 3;

[0026] The upper and lower surfaces of the Hafu component 3 are provided with molding cavities 301, which facilitates the fitting of the molding cavities 301 with the cavities of the upper mold plate 2 and the lower mold plate 5 respectively. The Hafu component 3 is provided with an injection port 305 inside, and the upper end of the injection port 305 penetrates through the upper surface of the Hafu component 3. The lower end of the injection port 305 is provided with a flow channel 302 that communicates with the inner side of the molding cavity 301, which facilitates the symmetry of the flow channels in the upper and lower layers and ensures a uniform injection effect between the upper and lower layers.

[0027] In this embodiment, preferably, the outer wall of the Hafu component 3 is fixed with a middle mold lifting frame 4 for adjusting its position, so as to facilitate the lifting of the Hafu component 3 when the finished product is removed later.

[0028] In this embodiment, preferably, a flow channel plate 1 is provided on the upper surface of the upper template 2, and the flow channel plate 1 is provided with a connection port 6 for cooperating with an external injection machine, so as to facilitate the injection of materials by cooperating with an external injection machine.

[0029] In this embodiment, preferably, guide blocks 303 are provided at both ends of the upper surface of the Hafu component 3, and guide grooves corresponding to the guide blocks 303 are provided on the lower surface of the upper template 2, so that the Hafu component 3 and the upper template 2 can be aligned during mold closing.

[0030] In this embodiment, preferably, multiple molding cavities 301 are evenly distributed along the long side of the Hafu component 3, which facilitates the simultaneous processing of multiple products.

[0031] In this embodiment, preferably, the lower surface of the upper template 2 is provided with a first mold cavity corresponding to the forming mold cavity 301, and the lower template 5 is provided with a second mold cavity corresponding to another forming mold cavity 301, so as to facilitate the molding of multiple products at one time.

[0032] The working principle and usage process of this utility model are as follows: During use, the material is injected into the inner side of the injection port 305 through the connection port 6, and flows simultaneously into the inner side of the molding cavity 301 on the upper and lower surfaces of the Hafu component 3 through two flow channels 302. It is formed in the inner side of the molding cavity 301 and the first mold cavity, and the second mold cavity and the other molding cavity 301. The improved structure ensures the consistency of the flow rate of the double-layer rubber material. At the same time, compared with the traditional structure, the processing difficulty and cost of the Hafu structure flow channel are greatly reduced. It can be cut and processed vertically. The new structure not only ensures the accuracy of the vulcanization time and improves the product quality, but also reduces the processing difficulty.
