Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically, to a molding device. Background Art

[0002] An injection mold is a tool for producing plastic products and also a tool for endowing plastic products with a complete structure and precise dimensions. For small products, a single mold is often used for injection molding. Although the injection efficiency can be improved, all cavities of the injection mold are injected through a single main injection runner. Therefore, the main injection runner is generally arranged at a position relatively close to all cavities. When the molten plastic flows over a long distance at the material inlet, it often hardens due to temperature drop. There are differences in the quality of the products produced by the cavities close to the main injection runner and those far from the main injection runner, and the products are prone to shrinkage and deformation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0062] Refer to Figure 1-4 As shown, this embodiment provides a molding device, including:

[0063] Upper top plate 1, female disk 2, male disk 3, cube 6, lower bottom plate 7 and cooling unit. A material port 16 is provided on the surface of the upper top plate 1. The material port 16 penetrates through the upper top plate 1 and the upper surface of the female disk 2. The material port 16 is used to pour molten plastic into the female disk 2. The upper top plate 1 is fixedly connected to the upper surface of the female disk 2. The lower surface of the female disk 2 fits against the upper surface of the male disk 3. The two sides of the lower surface of the male disk 3 are fixedly connected to the upper surface of the cube 6. The lower surface of the cube 6 is fixedly connected to the upper surface of the lower bottom plate 7.

[0064] It can be understood that a molding device involves multiple components and their connection methods. The core parts of the device are the upper top plate 1, female disk 2, male disk 3 and cube 6. The upper top plate 1 is connected to the female disk 2 by a fixed connection method. The female disk 2 is closely attached to the male disk 3. The two sides of the male disk 3 are fixedly connected to the cube 6, and the cube 6 is connected to the lower bottom plate 7. The device adopts fixed connections of components to enhance the stability and functionality of the overall structure. In addition, a cooling unit is also integrated into the device to ensure that the device maintains an appropriate temperature during operation. Through this precise design and multiple connections, the device can achieve efficient and stable operation, meeting the quality requirements of the mold for the product.

[0065] Refer to Figure 5-6 As shown, in some examples of the present application, the female disk 2 of a molding device includes:

[0066] Female mold core 18, first positioning concave blocks 12 and female mold core 29. The female mold core 18 is embedded in the female disk 2. A number of first positioning concave blocks 12 are provided around the female disk 2. The female mold core 29 is embedded in the female mold core 18.

[0067] It can be understood that a number of first positioning concave blocks 12 are provided around the female disk 2, and preferably 1 first positioning concave block 12 is provided in the middle of the four sides. The female mold core 18 is a core component embedded in the female disk 2, playing an important supporting and positioning role. 1 first positioning concave block 12 is provided around the female disk 2. These first positioning concave blocks 12 are used for precise positioning and fixing of the female mold core 18, ensuring the stability and accuracy of the entire mold device during operation. The female mold core 29 is further embedded inside the female mold core 18, forming a tight nested structure. Through this multi-layer embedding design, the mold can achieve high-precision molding and processing. This structure not only enhances the overall stability of the mold, but also improves its service life and working efficiency, improves the quality of the molten plastic filling the mold product, and ensures that the molten plastic can quickly and evenly fill the mold.

[0068] Refer to Figure 7 As shown, in some examples of the present application, the male disk 3 of a molding device includes:

[0069] The male mold core 19, the first positioning protrusion 13 and the male mold core 30, the male mold core 19 is embedded in the male disk 3, the male mold core 19 and the female mold core 18 are fitted together, and a plurality of first positioning protrusions 13 are arranged around the male disk 3, the first positioning protrusions 13 and the first positioning recessed blocks 12 are fitted together, and the male mold core 30 is embedded in the male mold core 19.

[0070] Specifically, a plurality of first positioning protrusions 13 are arranged around the male disk 3, and preferably one first positioning protrusion 13 is arranged in the middle of the four sides. The male mold core 19 is embedded in the male disk 3 and fits tightly with the female mold core 18 to achieve precise alignment and combination. A first positioning protrusion 13 is arranged around the male disk 3, and the four first positioning protrusions 13 correspond to and fit with the four first positioning recesses 12 on the female disk 2, ensuring that the male mold core 19 and the female mold core 18 can be accurately aligned during operation, thereby ensuring the molding accuracy. The male mold core 30 is further embedded in the male mold core 19. This design enables a highly consistent fit between the male mold core 19 and the female mold core 18, thereby improving the processing accuracy and stability of the mold. Through the mutual fitting of the male mold core 19 and the female mold core 18, and the first positioning protrusion 13 and the first positioning recessed block 12, the mold can maintain good stability and consistency during the high-precision molding process, ensuring that the molten plastic can quickly and evenly fill the mold, and preventing the leakage of molten plastic due to mold fitting errors during the fitting process, thereby affecting the stability and safety of the device.

[0071] It is understandable that a molding device selects the fit of four first positioning concave blocks 12 and four first positioning convex blocks 13, which can provide multi-point positioning, so that the various parts of the mold can be accurately aligned when the mold is closed. This four-point positioning can effectively reduce deviations and ensure the high precision of the mold during operation. In addition, the four positioning points can improve the stability and rigidity of the mold, prevent the mold from displacement or shaking during operation, and ensure the quality of the molded product. The four positioning points enable the mold to evenly distribute stress when it is subjected to force, reduce the situation where a single point is subjected to excessive force, extend the service life of the mold, and reduce the risk of wear and damage. The four-point positioning makes the installation and disassembly of the mold more convenient, reduces the time for alignment and adjustment, and improves production efficiency. In the case of transportation by high-temperature molten plastic, the four-point positioning can effectively limit the thermal expansion and deformation of the mold, ensure that the mold can maintain a stable shape and size under different working conditions, and then ensure the molding of the product, and avoid the product being affected by the temperature of the molten plastic.

[0072] In some examples of the present application, a cooling unit of a molding device includes:

[0073] A first water inlet 9, a first water outlet 8, a second water inlet 11 and a second water outlet 10. The female plate 2 is provided with the first water inlet 9 and the first water outlet 8, and the male plate 3 is provided with the second water inlet 11 and the second water outlet 10. The surfaces of the first water inlet 9 and the first water outlet 8 are embedded in the female plate 2, and the surfaces of the second water inlet 11 and the second water outlet 10 are embedded in the male plate 3.

[0074] Specifically, the female plate 2 is provided with the first water inlet 9 and the first water outlet 8. The surfaces of these water inlets and outlets are embedded in the female plate 2, and their water pipelines are embedded in the female die core 18. Similarly, the male plate 3 is provided with the second water inlet 11 and the second water outlet 10. The surfaces of these water inlets and outlets are embedded in the male plate 3, and the water pipelines are embedded in the male die core 19. This device adjusts the temperature of the mold through an effective cooling unit, ensuring that the mold maintains an appropriate temperature during operation to improve the molding quality and extend the service life of the mold. Specifically, the setting of the first water inlet 9 and the first water outlet 8 enables the coolant to circulate between the female plate 2 and the female die core 18. Similarly, the design of the second water inlet 11 and the second water outlet 10 enables the coolant to circulate between the male plate 3 and the male die core 19, ensuring the temperature control of the male plate 3 part, taking away the heat generated during operation, so that after the poured molten plastic is transported to the die core, effective cooling is carried out, cooling the high-temperature molten plastic into a mold, and ensuring the quality of the product.

[0075] It can be understood that for the cooling unit of a molding device, by separately setting independent water inlets and outlets on the female plate 2 and the male plate 3, precise temperature control of different parts of the mold can be achieved, ensuring temperature uniformity and stability during the molding process. The embedded water inlet and outlet design can improve the flow efficiency of the coolant, quickly take away the heat on the mold surface, shorten the cooling time, improve production efficiency. The water inlets and outlets are embedded inside the mold, making the entire cooling unit more compact, not affecting the shape and operation of the mold, saving space. Effective temperature control can reduce the stress and deformation of the mold caused by thermal expansion and contraction, reduce wear, and improve the service life of the mold.

[0076] In some examples of this application, a molding device includes:

[0077] The inner wall of the cube 6 is attached to the front plate 4 and the bottom plate 5. The lower surface of the front plate 4 is fixedly connected to the upper surface of the bottom plate 5. The surface of the upper top plate 1 is provided with a material port 16. The material port 16 penetrates through the upper surface of the upper top plate 1 and the female plate 2. A nozzle 17 is provided below the material port 16. The nozzle 17 penetrates through the female plate 2 and the female die core 18. A gate 21 is provided below the nozzle 17. The gate 21 is located at the middle position of the connection between the female die core 18 and the male die core 19. The bottom plate 5 is provided with a plurality of ejector pins 20. The ejector pins 20 penetrate through the front plate 4, the male plate 3 and the male die core 19. The upper part of the ejector pin 20 is tightly connected to the male die core 30.

[0078] Specifically, a material inlet 16 is provided on the surface of the upper top plate 1. The material inlet 16 penetrates through the upper top plate 1 and the upper surface of the female plate 2 to form a channel. A nozzle 17 is provided at the lower part of the material inlet 16. The nozzle 17 penetrates through the female plate 2 and the female mold core 18 to ensure that the molten material can smoothly flow into the mold cavity. The lower part of the nozzle 17 is connected to a gate 21. The gate 21 is located at the middle position of the connection between the female mold core 18 and the male mold core 19, which is the key channel for the molten material to enter the mold cavity. A number of ejector pins 20 are provided on the bottom positive plate 5. These ejector pins 20 penetrate through the surface positive plate 4, the male plate 3, and the male mold core 19 and are tightly connected to the male mold core 30. The main function of the ejector pins 20 is to eject the formed part from the mold after the molding process is completed, ensuring the smooth demolding of the product and improving production efficiency.

[0079] It can be understood that the settings of the material inlet 16, the nozzle 17, and the gate 21 form a continuous channel, ensuring that the high-temperature molten material can smoothly enter the mold cavity and guaranteeing the efficiency and molding quality of the injection molding process. The gate 21 is set at the middle position of the connection between the female mold core 18 and the male mold core 19, which can ensure uniform distribution of the material and reduce the defect of unevenness during product injection molding. The precise positioning of the nozzle 17 and the gate 21 can control the flow path and speed of the high-temperature molten material, ensuring the quality and precision of the formed part. Such a design helps to reduce problems such as air bubbles and uneven cooling, improving the quality of the finished product. The ejector pins 20 provided on the bottom positive plate 5 penetrate through the surface positive plate 4, the male plate 3, and the male mold core 19 and are connected to the male mold core 30, achieving efficient demolding. After the molding process is completed, the ejector pins 20 eject the formed part from the mold through the ejection action, ensuring the smooth demolding of the product, reducing manual intervention, and improving production efficiency. This design makes the entire device structure compact, with tight connections between various parts, not only saving space but also improving the stability and reliability of the entire device. The embedded design ensures the firm connection of each component and reduces the failure rate.

[0080] In some examples of the present application, a molding device includes:

[0081] A first adjustment unit 27 is provided at the middle position of the female mold core 18, and a number of second positioning recesses 25 are provided at the four corners of the female mold core 18. A second adjustment unit 28 is provided at the middle position of the male mold core 19, and a number of second positioning protrusions 26 are provided at the four corners of the male mold core 19.

[0082] Specifically, several second positioning recesses 25 are provided at the four corners of the female mold core 18, preferably one for each of the four-corner second positioning recesses 25. Several second positioning protrusions 26 are provided at the four corners of the male mold core 19, preferably one for each of the four-corner second positioning protrusions 26. A first adjusting unit 27 is provided at the middle position of the female mold core 18. This first adjusting unit is used to precisely adjust the position and angle of the female mold core 18 to ensure precise alignment and stability of the mold during operation. In addition, second positioning recesses 25 are provided at the four corners of the female mold core 18, and these second positioning recesses 25 correspond to the second positioning protrusions 26 on the male mold core 19, further enhancing the positioning accuracy and stability of the mold. A second adjusting unit 28 is provided at the middle position of the male mold core 19, corresponding to the first adjusting unit 27 of the female mold core 18. Through the mutual cooperation of these two adjusting units, the overall position and angle of the mold can be precisely adjusted to ensure high consistency and accuracy of the mold during operation. Second positioning protrusions 26 are provided at the four corners of the male mold core 19, and these second positioning protrusions 26 correspond to the second positioning recesses 25 on the female mold core 18. Through the precise fitting of the second positioning protrusions 26 and the second positioning recesses 25, high-precision alignment of the mold is achieved.

[0083] It can be understood that by adjusting the first adjusting unit 27 and the second adjusting unit 28 by technicians, the position and angle of the female mold core 18 are adjusted to adjust the injection-molded product. For example: the injection-molded product is bent, and an arched structure is actually made on the mold; the product is concave when it is molded, and a convex structure is actually made on the mold and then the product is flattened. This can make the injection-molded product made of 4-mm-thick polycarbonate material not easily shrink and deform, increasing the selectivity of the material used. The second positioning recesses 25 and the second positioning protrusions 26 at the four corners of the female mold core 18 and the male mold core 19 cooperate with each other, and high-precision alignment of the mold is achieved through a four-point positioning method. This design reduces the offset and displacement of the mold during operation, ensuring the consistency and quality of the molded product. The design of the first adjusting unit 27, the second adjusting unit 28, the second recess 25 and the second protrusion 26 makes the installation, adjustment and maintenance of the mold more convenient. The first adjusting unit 27 and the second adjusting unit 28 provide convenient adjustment means, while the precise alignment of the second recess 25 and the second protrusion 26 reduces the time for alignment and adjustment, improving the production efficiency and the maintenance efficiency of the mold. The precise adjustment and positioning mechanism reduces the stress and wear of the mold during operation, thereby extending the service life of the mold. By reducing the wear and damage caused by position deviation, the durability of the mold is improved.

[0084] In some examples of the present application, a locking mechanism 15 of a molding device includes:

[0085] The locking mechanism 15 is fixedly connected to the outer surface of the male plate 3. A locking groove is provided on the upper part of the locking mechanism 15, and a screw hole is provided on the outer surface of the female plate 2. The locking grooves and the screw holes correspond to each other one by one, and the locking grooves are in fit with the screw holes.

[0086] Specifically, the locking mechanism 15 is fixedly connected to the outer surface of the male plate 3. Its main function is to ensure that the male plate 3 and the female plate 2 are tightly combined during the non-working process, prevent loosening or displacement, so as to ensure the precision of the mold. An independent locking groove is provided on the upper part of the locking mechanism 15, and the locking grooves correspond to the screw holes provided on the surface of the female plate 2 one by one. When not working, the locking grooves are in fit with the screw holes, and the technician tightens bolts on the screw holes to achieve precise locking and fixation, ensuring that the mold can still maintain stability and reliability in the non-working environment.

[0087] It can be understood that the locking mechanism 15 is fixedly connected to the outer surface of the male plate 3, and precise alignment and locking are achieved through the locking grooves and the screw holes on the female plate 2. This design ensures that the mold will not loosen or displace during the non-working process, improving the stability and safety of the mold. The locking grooves and the screw holes correspond to each other one by one, ensuring that the locking points can be precisely aligned. Through the tight fit between the locking grooves and the screw holes, the structural stability of the entire mold is significantly improved. The design of the locking mechanism 15 provides additional safety protection, preventing the mold from accidentally loosening or being damaged due to insufficient locking in other environments. This design ensures the safety of the operator and the continuity of the production process.

[0088] In some examples of the present application, a molding device includes:

[0089] The lower bottom plate 7 is provided with positioning pin columns 22. The positioning pin columns 22 penetrate the surface positive plate 4, the bottom positive plate 5 and the male plate 3, and the positioning pin columns 22 are in fit with the lower surface of the female plate 2. A spiral spring 23 is sleeved on the positioning pin columns 22. The upper part of the spiral spring 23 is fixedly connected to the upper surface of the male plate 3, and the lower part of the spiral spring 23 is fixedly connected to the upper surface of the surface positive plate 4.

[0090] Specifically, the lower bottom plate 7 is provided with positioning pin columns 22. The positioning pin columns 22 penetrate the surface positive plate 4, the bottom positive plate 5 and the male plate 3 and are in fit with the lower surface of the female plate 2. This design ensures precise alignment and tight connection between the various parts of the mold, thus ensuring the stability and high efficiency of the mold during the working process. A spiral spring 23 is sleeved on the positioning pin columns 22. The upper part of the spiral spring 23 is fixedly connected to the upper surface of the male plate 3, and the lower part is fixedly connected to the upper surface of the surface positive plate 4. The spiral spring 23 plays a buffering and stabilizing role in the mold device, ensuring that the mold can withstand the working pressure during the high-pressure injection molding process and reducing impact and vibration at the same time.

[0091] It can be understood that the positioning pin column 22 penetrates through multiple mold components and fits against the lower surface of the female plate 2, ensuring precise alignment and stable connection between various parts of the mold. The helical spring 23 is sleeved on the positioning pin column 22, providing additional buffering and shock absorption effects. During the high-pressure injection molding process, the helical spring 23 can effectively absorb impact force and vibration, reduce wear and damage between various parts of the mold, thereby extending the service life of the mold. Through the bidirectional fixed connection of the helical spring 23, the stability of the entire mold device is significantly enhanced. The helical spring 23 provides continuous pressure and support during the working process, ensuring that various parts of the mold always maintain close fit and stability. The precise positioning and effective buffering and shock absorption design enable the mold to maintain an efficient and stable working state during the high-pressure injection molding process. It reduces production interruptions and product rejection rates caused by mold displacement or vibration, thereby improving the overall production efficiency and finished product quality. During the working process, the spring contracts, causing several ejector pins 20 of the bottom positive plate 5 to lift, ejecting the molded part from the mold, ensuring smooth demolding of the product and improving production efficiency.

[0093] The lower bottom plate 7 is provided with several guide columns 24, the guide columns 24 penetrate through the male plate 3, and the guide columns 24 fit against the lower surface of the female plate 2.

[0094] It can be understood that several guide columns 24 are provided on the lower bottom plate 7, these guide columns 24 pass through the male plate 3, and fit against the lower surface of the female plate 2. The main function of the guide columns 24 is to ensure precise alignment between various parts of the mold. Through the support and guiding action of the guide columns 24, the male plate 3 and the female plate 2 can be accurately aligned, avoiding displacement or deviation during the high-pressure injection molding process. This design improves the molding accuracy of the mold, and also enhances the stability and reliability of the mold during operation.

[0095] In some examples of the present application, a connecting plate 14 of a molding device includes:
