[0029] The utility model provides an inverted mold base structure. When a first template is arranged on the ground, an injection molding component is inserted into a second template. A glue inlet of the injection molding component faces a first mold core in the first template. After such an inverted mold base structure completes injection molding of a mold cavity through the glue inlet, the mold is opened, and an ejector pin component moves to eject the product in the mold cavity. Since the second mold core and the ejector pin component can move relatively, the mold core can dissipate heat better, and the utility model can be suitable for producing products with high requirements for appearance surface effects. Example

[0030] The utility model embodiment provides a flip mold base structure, such as Figures 1 to 3As shown, it includes: a first template 1, the first template 1 is provided with a first mold core 11; a second template 2, the second template 2 is provided with a relatively movable second mold core 21 and a ejector assembly 22; an injection molding assembly 3, the injection molding assembly 3 is penetrated by the second template 2, and the glue inlet 31 of the injection molding assembly 3 faces the first mold core 11; after the first template 1 and the second template 2 are molded together, a mold cavity 4 is provided between the first mold core 11 and the second mold core 21.

[0031] Such an inverted mold base structure mainly consists of three parts: a first mold plate 1, a second mold plate 2 and an injection molding component 3. This structure is particularly suitable for the production of products that require a specific injection method or have high requirements for mold core heat dissipation. The first mold plate 1 is provided with a first mold core 11, which is a part of the mold cavity 4.

[0032] The first template 1 is usually fixed on the ground as the base of the mold. The second template 2 may be equipped with an ejector assembly 22, which can move when the mold is opened to eject the product in the mold cavity 4.

[0033] The structure of the second template 2 allows the second mold core 21 and the ejector assembly 22 to move relative to each other, which helps to dissipate heat from the mold core. The injection molding assembly 3 is inserted into the second template 2, and its injection port 31 faces the first mold core 11 in the first template 1. This injection method can meet the special requirements of some products for the injection position.

[0034] An exemplary description is given of one possible working principle of an inverted mold base structure provided by an embodiment of the utility model: after the first template 1 and the second template 2 are molded together, a mold cavity 4 is formed between the first mold core 11 and the second mold core 21. The injection molding component 3 is controlled by the injection molding machine and is responsible for injecting the molten plastic into the mold cavity 4. The injection molding component 3 injects the molten plastic into the mold cavity 4 through the glue inlet 31. After the injection molding is completed, the plastic in the mold cavity 4 is gradually cooled and solidified under the cooling effect of the mold core. The mold is opened, and the ejector assembly 22 in the second template 2 starts to move to eject the product in the mold cavity 4. Since the second mold core 21 and the ejector assembly 22 can move relative to each other, the mold core can better dissipate heat during the injection molding and cooling process to avoid excessive temperature of the mold core. In this way, by using the built-in ejector assembly 22, the use of an inverted hot nozzle for injection molding is achieved without affecting the production ejection, and it is used to produce products with high requirements for appearance effects and large product glue surfaces.

[0035] like Figure 3As shown, more specifically, the ejector assembly 22 includes an ejector plate 221 and an ejector member 222, and the second mold core 21 is arranged between the ejector plate 221 and the first mold core 11. Among them, the ejector member 222 can be used to eject the product in the mold cavity 4. The ejector assembly 22 is composed of the ejector plate 221 and the ejector member 222, which can stably and efficiently eject the product from the mold cavity 4. Among them, the ejector plate 221 can be a supporting structure of the ejector member 222, and the ejector member 222 is used to eject the product in the mold cavity 4.

[0036] like Figure 2 and Figure 3 As shown, more specifically, the ejector member 222 is provided in the second mold core 21, one end of the ejector member 222 is connected to the ejector plate 221, and the other end is arranged toward the mold cavity 4. In this way, a more open or larger heat dissipation space 23 can be formed between the second mold core 21 and the ejector plate 221 to enhance the heat dissipation effect of the mold core. Since the ejector member 222 is provided in the second mold core 21 and an open heat dissipation space 23 is formed between the ejector plate 221 and the second mold core 21, the mold core can dissipate heat better during the injection molding and cooling process, reduce the mold core temperature, and improve product quality and production efficiency.

[0037] like Figure 2 and Figure 3 As shown, more specifically, the ejector assembly 22 includes a plurality of ejector parts 222. The structure of the plurality of ejector parts 222 can better eject products with a larger glue surface or can be suitable for ejecting different types of products. In this way, the ejector assembly 22 includes a plurality of ejector parts 222, and these ejector parts 222 can be evenly distributed at the bottom of the mold cavity 4, ensuring that the product is evenly stressed during the ejection process, and avoiding deformation or damage of the product.

[0038] The structure of multiple ejector parts 222 can also be flexibly adjusted according to the shape and size of the product to adapt to different types of products. Each ejector part 222 can be inserted into the second mold core 21, one end is connected to the ejector plate 221, and the other end is arranged toward the mold cavity 4. This structure ensures the stability and reliability of the ejector part 222 during the ejection process. The connection between the ejector part 222 and the ejector plate 221 can be achieved by threads, pins or other fastening methods to ensure the firmness of the connection. Since multiple ejector parts 222 are inserted into the second mold core 21, empty heat dissipation spaces 23 are formed between them and between the ejector plate 221. These spaces help the mold core to dissipate heat during injection molding and cooling, and reduce the mold core temperature. Good heat dissipation performance can not only improve product quality and production efficiency, but also extend the service life of the mold. When the mold is opened, the ejector plate 221 drives multiple ejector parts 222 to move forward at the same time to evenly eject the product in the mold cavity 4. Due to the uniform distribution and simultaneous action of the plurality of ejector pins 222, the product can be smoothly released from the mold without deformation or damage.

[0039] Advantages of ejector assembly 22: Wide adaptability. The structure of multiple ejector components 222 enables ejector assembly 22 to adapt to products of different types or with larger glue surfaces, thus improving the versatility and flexibility of the mold. Good ejection effect. Since multiple ejector components 222 act simultaneously, the product can be smoothly separated from the mold, thus avoiding deformation or damage caused by uneven force. Excellent heat dissipation performance. The open heat dissipation space 23 formed between ejector component 222 and ejector plate 221 helps to dissipate heat from the mold core, reduces the mold core temperature, and improves product quality and production efficiency.

[0040] More specifically, a flexible part 223 may be provided on one end of the ejector part 222 facing the mold cavity 4. The flexible part 223 may be a part of the ejector part 222, or may be an additional part provided on the ejector part 222. By providing the flexible part 223, the ejector part 222 may reduce the possibility of damaging the product when ejecting the product. The flexible part 223 may be directly integrated into the structure of the ejector part 222. This means that one end of the ejector part 222 may be an end facing the mold cavity 4 and may have the characteristics of a flexible material, such as being made of rubber, silicone or other elastic materials. This allows the ejector part 222 to have greater cushioning when in contact with the product, thereby reducing direct impact and damage to the product.

[0041] The flexible member 223 also exists as an additional component of the ejector pin 222. This usually involves putting a flexible sleeve, pad or other similar component on the top of the ejector pin 222. The material and thickness of the flexible member 223 can be selected according to the specific requirements of the product to ensure the best cushioning effect.

[0042] The main function of the flexible member 223 is to reduce the direct impact of the ejector member 222 on the product when ejecting the product. This is particularly important for products made of fragile or sensitive materials because it can significantly reduce the risk of product damage.

[0043] The flexible member 223 can also increase the adaptability of the ejector member 222 to different types of products. Since the flexible member 223 has a certain deformation ability, it can better adapt to products of different shapes and sizes, thereby improving the versatility and flexibility of the mold. By reducing damage to the product and enhancing adaptability, the flexible member 223 can also indirectly extend the service life of the mold. Because the frequency of product damage and mold maintenance is reduced, production costs and time are reduced.

[0044] The material of the flexible member 223 may have good elasticity and wear resistance to ensure its stability and reliability in long-term use. Common materials include rubber, silicone, polyurethane, etc. The size and shape of the flexible member 223 should be selected according to the specific requirements of the product. For example, for a smaller product, the flexible member 223 can be designed as a smaller circle or square; while for a larger product, a larger flexible member 223 is required to provide sufficient cushioning effect.

[0045] like Figures 1 to 3 As shown, the ejector assembly 22 may further include a driving member 224, which is connected to the ejector plate 221 and / or the ejector member 222. The driving member 224 may be used to drive the ejector plate 221 and / or the ejector member 222 to move, so as to achieve movement between the ejector plate 221 and the second mold core 21, or to control the ejector member 222 to move to eject the product. More specifically, the driving member 224 may be a cylinder. In this way, the driving member 224 may be the power source in the ejector assembly 22, responsible for driving the ejector plate 221 and / or the ejector member 222 to move.

[0046] The driving member 224 can be selected as a cylinder, which has the advantages of stable power, rapid response, easy control, etc. During the mold opening process, the driving member 224 drives the ejector member 222 to move forward to eject the product from the mold cavity 4.

[0047] Among them, the cylinder has stable power, which can ensure the stability and consistency of the ejector 222 during the ejection process. The cylinder responds quickly and can quickly complete the movement of the ejector 222, thereby improving production efficiency. The cylinder is easy to control, and the moving speed and force of the ejector 222 can be controlled by adjusting the air pressure and flow. Of course, the selection and configuration of the driving member 224 can also be determined according to the specific mold structure and product requirements, that is, the driving member 224 can be a product other than a cylinder.

[0048] like Figure 3As shown, more specifically, it may be that it also includes a heat dissipation component 111, and the heat dissipation component 111 is arranged on the first mold core 11. In this way, the heat dissipation component 111 can be used to enhance the heat dissipation effect of the first mold core 11, so that the first mold core 11 and the second mold core 21 can have a good heat dissipation effect. In the inverted mold base structure provided in the embodiment of the utility model, in order to further improve the heat dissipation performance of the mold, especially when processing products that require higher heat dissipation efficiency, introducing the heat dissipation component 111 is a possible effective solution. The heat dissipation component 111 may include a variety of heat dissipation elements such as heat sinks and heat pipes. The heat sink can be made of high thermal conductivity materials, such as aluminum alloy, brass or bronze, which have a large surface area and high thermal conductivity, and can effectively transfer heat from the first mold core 11 to the air. The heat pipe uses the principle of liquid evaporation and condensation to achieve efficient heat transfer. The heat dissipation component 111 can be fixed to the first mold core 11 by bolts, welding or other fastening methods to ensure its stability and reliability during the working process of the mold. Good heat dissipation performance helps maintain the stability of the mold temperature and avoids quality problems such as product deformation and bubbles caused by mold overheating. The use of the heat dissipation component 111 can reduce the damage to the mold due to overheating, thereby extending the service life of the mold.

[0049] The heat dissipation component 111 cooperates with other components: The heat dissipation component 111 cooperates with other key components such as the ejector component 22 and the injection molding component 3 to ensure efficient and stable operation of the mold. The ejector component 22 is responsible for ejecting the product, while the heat dissipation component 111 is responsible for heat dissipation of the mold. The two cooperate with each other to enable the mold to maintain stable performance in a continuous and efficient production process.

[0050] Specifically, it may further include a heat dissipation space 23 . After the first mold plate 1 and the second mold plate 2 are molded together, a heat dissipation space 23 is provided between the second mold core 21 and the ejector plate 221 .

[0051] The following is an example of one possible working principle of an inverted mold base structure provided by the embodiment of the utility model: the raw material enters the mold cavity 4 through the glue inlet 31. After the injection molding is completed, the mold is opened, and the driving member 224 is started to drive the ejector assembly 22 to eject the product, and the ejector member 222 on the ejector plate 221 ejects the product. After the product is removed, the mold is reversed and reset to wait for the next mold opening. In this way, through the structure of the built-in cylinder combined with the built-in ejector assembly 22, the use of the inverted hot nozzle injection molding does not affect the production ejection, and is used to produce products with high requirements for the appearance effect and a large product glue surface.

[0052] Compared with the prior art, an inverted mold base structure provided by an embodiment of the utility model, when the first template is set on the ground, the injection molding component is inserted into the second template, and the glue inlet of the injection molding component faces the first mold core in the first template. After such an inverted mold base structure completes the injection molding of the mold cavity through the glue inlet, the mold is opened, and the ejector assembly moves to eject the product in the mold cavity. Since the second mold core and the ejector assembly can be relatively movable, the mold core can better dissipate heat, which can be suitable for producing products with high requirements for appearance surface effects.

[0053] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
