[0018] By adopting the above technical solution, the cooling holes are evenly distributed around the molding groove, which can ensure that each part of the mold dissipates heat evenly and prevent local overheating.

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1 The present invention discloses a forming die and forming process of an adapter housing. Figure 1 As shown, the molding die of the adapter shell includes a pad 1. The pad 1 serves as the base part of the mold and provides stable support to ensure that the entire mold does not deform during use. The upper surface of the pad 1 is fixedly connected with a base plate 2. The base plate 2 is fixed on the pad 1 to provide a flat surface for subsequent components and support the A plate 4. The material and thickness of the base plate 2 are usually designed to withstand the pressure generated during the molding process. A B plate 3 is fixedly installed on the upper surface of the base plate 2. The setting of the B plate 3 serves to connect and support the A plate 4. At the same time, it can be designed as a structure that is easy to replace or adjust to meet different molding requirements. An A plate 4 is arranged on the upper surface of the B plate 3. As a part of the molding die, the A plate 4 is directly involved in forming the shape and details of the adapter shell, and its design will determine the final appearance and function of the shell. A panel 5 is arranged on the upper surface of the A plate 4. The panel 5 is at the top layer and is usually used to form the surface of the shell, which directly affects the appearance and durability of the shell.

[0028] like Figure 1 As shown, the molding die of the adapter housing has a hierarchical structure that makes the function of each component clearer and facilitates manufacturing and maintenance; if a part is damaged, it can be replaced separately without remanufacturing the entire mold; moreover, the design of the A plate 4 and the panel 5 can ensure that the shape and size of the housing are accurate, meet the design requirements, and reduce the need for subsequent processing.

[0029] like Figure 1As shown, a flow plate 6 is provided between the panel 5 and the A plate 4. Specifically, the flow plate 6 is a structure inside the mold, located between the panel 5 and the A plate 4, and is mainly used for the flow of plastic or other fluid materials; its main function is to guide and control the distribution of the molten material in the mold cavity to ensure that the material evenly fills the entire mold.

[0030] like Figure 1 As shown, during the injection molding process, molten plastic is injected into the mold through a nozzle; the design of the runner plate 6 guides these molten materials to various parts of the mold; the runner plate 6 is provided with runners, the shapes and sizes of which are precisely calculated to optimize the fluidity and filling speed of the material, ensuring that the entire mold is quickly and evenly filled with material; the design of the runner plate 6 can also affect the efficiency of the cooling process, improve the molding cycle, and ensure that the material will not have defects when solidifying.

[0031] like Figure 1 As shown, the runner plate 6 helps ensure that the molten material can be evenly distributed to each part of the mold, reducing voids and defects and improving product quality; a good runner design can reduce the pressure loss of the molten material during the flow process, reduce energy consumption during the molding process, and improve molding quality.

[0032] like Figure 1 As shown, a sprue plate 7 is provided on the upper surface of the runner plate 6. Specifically, the sprue plate 7 is a component of the mold, which is installed on the upper surface of the runner plate 6. Its main function is to provide an inlet (i.e., a sprue) for the molten plastic, and also to help control the direction and speed of the material flow. The design of the sprue plate 7 directly affects the injection process of the molten material.

[0033] like Figure 1 As shown, the sprue plate 7 works together with the runner plate 6, and the sprue guides the molten plastic into the mold cavity through the runner; the sprue is usually designed to form a flow channel connected to the runner plate 6; the sprue plate 7 can control the flow speed and pressure of the material by adjusting the shape and size of the sprue, thereby optimizing the filling process; and during the injection molding process, the sprue plate 7 helps to maintain a stable pressure inside the mold to ensure the smooth flow of the molten material.

[0034] like Figure 1 As shown, therefore, the presence of the gate plate 7 can ensure the uniform distribution of the molten material in the mold, reduce voids and defects, and improve the quality of the final product; by controlling the flow speed and pressure of the molten material, the gate plate 7 can shorten the molding time and improve production efficiency.

[0035] like Figure 1 and Figure 2As shown, a first mounting cavity 8 is provided inside the B plate 3, and a rear mold core 9 for determining the rear shape of the molding adapter is fixedly installed in the first mounting cavity 8 of the B plate 3. A second mounting cavity is provided inside the A plate 4, and a front mold core 10 for determining the front shape of the molding adapter is fixedly installed in the second mounting cavity of the A plate 4. The rear mold core 9 and the front mold core 10 are matched with each other.

[0036] like Figure 1 and Figure 2 As shown, during the injection molding or die-casting process, the closure of plate A 4 and plate B 3 forms a complete mold structure, and the precise match between the front mold core 10 and the rear mold core 9 enables the molten material to fill the entire mold cavity; this precise match ensures the shape and size of the final product; after the mold is formed, the separation of plate A 4 and plate B 3 facilitates demolding, and the match between the front mold core 10 and the rear mold core 9 ensures a smooth process when the mold is opened, avoiding damage to the finished product; the design between the front mold core 10 and the rear mold core 9 can also affect the layout of the cooling channel, ensuring that the injected molten material can be evenly distributed and effectively cooled.

[0037] like Figure 1 and Figure 2 As shown, therefore, the close fit between the front mold core 10 and the rear mold core 9 can effectively control the size and shape of the molded part and achieve high-precision molding; a good mold clamping effect can reduce or eliminate welding marks that may appear during the injection molding process and improve the product appearance quality; and the disassembly and maintenance process of the mold is relatively simple, which improves the use efficiency and maintainability of the mold; by adjusting the design of the front mold core 10 and the rear mold core 9, it can better adapt to the production of different products and improve the versatility of the mold.

[0038] like Figure 1 and Figure 2 As shown, in summary, the design and structure of the A plate 4 and the B plate 3 realize an efficient, accurate and convenient molding process in mold manufacturing through the precise cooperation of the front mold core 10 and the rear mold core 9.

[0039] like Figure 1 and Figure 2 As shown, the front mold core 10 is provided with four first molding grooves 11, and the rear mold core 9 is provided with four second molding grooves 12 which are arranged corresponding to the first molding grooves 11. The first molding grooves 11 and the second molding grooves 12 correspond to each other, forming a good matching relationship. This design ensures that the molten material is evenly filled and pressed between the molds on both sides during the injection molding process, thereby promoting the fluidity and filling properties of the material.

[0040] like Figure 1 and Figure 2As shown, the design of the first molding groove 11 and the second molding groove 12 enables the molten material to be evenly pressurized during high-pressure injection molding; this helps to avoid excessive compression of the material in one direction, thereby reducing molding defects caused by uneven pressure.

[0041] like Figure 2 As shown, due to the corresponding design of the front mold core 10 and the rear mold core 9, the temperature and pressure in the entire molding process are balanced, which can effectively prevent the molded body from warping and deforming during the cooling process, ensuring that the molded product maintains its designed shape.

[0042] like Figure 2 As shown, the technical solution aims to optimize the molding process and improve the quality and appearance of the final product by opening four first molding grooves 11 and second molding grooves 12 on the front mold core 10 and the rear mold core 9 respectively, and combining the use of high-speed and high-pressure injection molding machines; the design of opening molding grooves on the mold core allows the molten material to be more evenly distributed to each area of ​​the mold, thereby effectively reducing molding defects such as clamping lines and flashing.

[0043] like Figure 2 As shown in the figure, by increasing the injection speed, the residence time of the molten material in the mold can be shortened, preventing the material from being degraded due to excessive temperature in the mold, thereby avoiding the occurrence of clamping line defects; increasing the injection pressure allows the molten material to quickly fill each molding groove of the mold, which can ensure that the molten material is completely filled in the mold without leaving any gaps, thus avoiding the flashing phenomenon caused by incomplete filling.

[0044] like Figure 1 and 2 As shown, guide pins 13 are provided at the four inner corners of the B plate 3, and the guide pins 13 match the guide holes 14 provided in the A plate 4. The guide pins 13 are inserted into the guide holes 14 in the A plate 4 to achieve precise alignment, so that the B plate 3 and the A plate 4 are strictly aligned during installation or operation; this design can ensure the relative position between the two plates is stable; and the shape and size of the guide pins 13 are designed to match the guide holes 14 to ensure that no offset occurs during movement or assembly, thereby controlling the positioning and movement of the components.

[0045] Example 2 like Figure 3 As shown, the molding process of the molding die of the adapter housing includes the following molding steps: S1: mold closing During the injection molding or die casting process, the A plate 4 and the B plate 3 of the mold are first closed to form a complete mold structure. This process requires ensuring that there is no gap between the two plates to avoid material leakage; in addition, the centering accuracy of the mold closing mechanism should be checked to ensure tightness and subsequent molding quality.

[0046] S2: Exact match The precise matching between the front mold core 10 and the rear mold core 9 is crucial, as their combination ensures that the molten material can effectively fill the entire mold cavity. At this stage, the mold core surface flatness and wear should be checked to prevent molding defects caused by unevenness. The docking design of the first molding groove 11 and the second molding groove 12 should be repeatedly checked to ensure correctness.

[0047] S3: Material injection When the mold is closed, the molten material is injected into the mold through the injection device. The injection process should maintain a constant temperature and pressure to form a stable flow. The design concept of the first molding groove 11 and the second molding groove 12 ensures that the material can be evenly distributed in the mold to prevent accumulation and the generation of bubbles.

[0048] S4: Pressure is evenly distributed During the high-pressure injection stage, the design of the double molding grooves allows the molten material to be subjected to uniform pressure. This design can effectively reduce excessive compression of the material in a certain direction and avoid molding defects such as bubbles and cracks. Therefore, it is also very important to monitor the pressure changes and flow of the injection molding machine to ensure the stability of the entire process.

[0049] S5: Mold cooling After the mold is formed, the layout of the cooling channel directly affects the cooling efficiency of the molten material. Through reasonable cooling channel design, the material is ensured to be cooled evenly to maintain the physical properties and appearance quality of the finished product. During the cooling stage, the temperature and pressure should be checked regularly to ensure the consistency of the cooling process.

[0050] S6: Parting After molding is completed, the A plate 4 and the B plate 3 are separated by a mechanical system for demoulding. In this process, the matching design of the front mold core 10 and the rear mold core 9 should ensure that the mold is opened smoothly without causing damage to the finished product. The use of appropriate mold separation oil and auxiliary devices can reduce the adhesion of the finished product and ensure smooth demoulding.

[0051] S7: Finished product inspection Finally, the finished product is inspected to ensure that the shape, size and surface quality meet the design standards. This step includes visual inspection, dimensional measurement, surface roughness test and necessary functional test. If defects are found, the cause should be analyzed in time, and corrections and adjustments should be made to improve the quality of the next production.

[0052] The effective implementation and control of each of the above steps are the key to ensuring the quality of the final product. By strictly following these molding process steps, defects can be minimized and the qualified rate of finished products can be increased to meet market demand.

[0053] Example 3 like Figure 4 As shown, cooling holes 15 are provided inside the B plate 3 and the A plate 4. There are a plurality of cooling holes 15, and the cooling holes 15 are evenly distributed around the outer sides of the first molding groove 11 and the second molding groove 12. Cooling pipes 16 are fixedly installed in the cooling holes 15 of the B plate 3 and the A plate 4.

[0054] like Figure 4 As shown, during the molding process, the mold will heat up due to the high temperature of the material; the cooling holes 15 and the cooling pipes 16 are designed to remove excess heat by providing a cooling medium (such as water or coolant). The cooling holes 15 are evenly distributed around the molding groove to ensure that each part of the mold dissipates heat evenly and prevents local overheating. The coolant in the cooling pipe 16 circulates between different temperature zones, thereby achieving continuous temperature control and keeping the mold within a certain operating temperature range.

[0055] like Figure 4 As shown in the figure, by maintaining a uniform and appropriate temperature, defects caused by temperature differences during the molding process can be reduced, and the consistency and quality of the product can be improved. Timely cooling can shorten the cooling time, thereby improving production efficiency and reducing production cycles.

[0056] Working principle: First, the A plate 4 and the B plate 3 are closed to form a complete mold structure. This closing action ensures the sealing of the mold and prepares for the subsequent material injection.

[0057] When the mold is closed, the molten material is injected into the mold to fill the first molding groove 11 and the second molding groove 12. This process requires the injected material to have good fluidity to ensure that no voids or defects occur.

[0058] After the molding is completed, the A plate 4 and the B plate 3 are separated, which makes demoulding more convenient. The matching design between the front mold core 10 and the rear mold core 9 further ensures the stability of the mold opening process and effectively reduces the resistance and damage that may occur during demoulding.

[0059] Finally, after demolding, the finished product is inspected to ensure that its shape, size and surface quality meet the design standards. Through this series of steps, an efficient and accurate production process from material injection to product molding is achieved.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
