Therefore, they should not be construed as limitations on this invention.

[0027] In the description of this invention, "a number of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0029] like Figure 1-6 As shown, an in-mold integrated molding die is provided, including a fixed mold assembly, a moving mold assembly, a diaphragm positioning assembly, a gating system, an ejection system, and a cooling system.

[0030] like Figure 1 and 2 As shown, the fixed mold assembly includes a fixed template 13, a fixed mold core, four precision positioning plates 20, and four guide sleeves 22. The fixed mold core is located in the middle of the fixed template 13. Positioning grooves are provided at each of the four corners of the fixed template 13. The guide sleeves 22 are located at the bottom of the positioning grooves and extend into the interior of the fixed template 13. The precision positioning plates 20 are fixedly installed on the groove walls. The moving mold assembly includes a moving template, a moving mold core 26, four precision positioning blocks 24, four guide pillars 23, and a moving mold clamping block 25. The moving mold core is located in the middle of the moving template. The precision positioning blocks 24 are adapted to the positioning grooves and abut against the precision positioning plates 20. The guide pillars 23 are fixedly installed on the precision positioning blocks 24 and sleeved with the guide sleeves 22. The moving mold core 26 is installed on the moving template through the moving mold clamping block 25.

[0031] The fixed mold plate 13 and the moving mold plate cooperate with each other, and the fixed mold core and the moving mold core 26 cooperate with each other. The precision positioning plate 20 of the fixed mold assembly and the precision positioning block 24 of the moving mold assembly cooperate with each other to form a precision positioning structure. This precision positioning structure is then fixed by the guide sleeve 22 and the guide post 23 to ensure the precise alignment of the fixed mold assembly and the moving mold assembly during the mold closing process, thereby achieving high-precision molding quality.

[0032] like Figure 4As shown, the diaphragm positioning assembly includes a diaphragm 28, diaphragm pins, diaphragm positioning pins 27, and diaphragm pin holes 19. The number of diaphragm pins, diaphragm positioning pins 27, and diaphragm pin holes 19 corresponds one-to-one. In this embodiment, there are four diaphragm pins. The diaphragm 28 is located between the fixed mold core and the moving mold core 26, and the cavity formed by these three is designated as the product molding cavity. The product 30 is integrally injection molded within the product molding cavity. Therefore, depending on the different shapes of the product 30, the structure of the diaphragm 28, the fixed mold core, and the moving mold core 26, as well as their spatial arrangement, can be changed to achieve integral injection molding of products 30 with different shapes. Four diaphragm pins are fixedly connected to the outer wall of the diaphragm 28. The diaphragm pins have diaphragm positioning waist-shaped holes 29. The diaphragm positioning pins 27 are fixedly installed on the moving mold core 26. The fixed mold core has diaphragm pin holes 19, and the diaphragm positioning pins 27 pass through the diaphragm positioning waist-shaped holes 29 and connect to the diaphragm pin holes 19.

[0033] The diaphragm positioning waist-shaped holes 29 are all 9x4mm in size. By precisely aligning the diaphragm positioning pins 27 and the diaphragm positioning waist-shaped holes 29, the position of the diaphragm 28 is ensured to remain within acceptable limits. This improves the positioning accuracy of the diaphragm 28, enhances the stability of the integrated forming and punching operation of the diaphragm 28, and increases the yield rate of the formed diaphragm 28.

[0034] like Figure 3 As shown, the gating system includes a hot runner main gate 38, a hot runner manifold 36, a hot runner nozzle 35, a cold runner 17, a submarine gate 32, a gate sprue 31, a valve needle 34, a valve needle control cylinder 37, a hot runner plug 2, and a valve needle hydraulic connector 3. The hot runner main gate 38 is connected to the hot runner manifold 36, the hot runner manifold 36 is connected to the hot runner nozzle 35, the hot runner nozzle 35 is connected to the cold runner 17, the cold runner 17 is connected to the submarine gate 32, the submarine gate 32 slides with the gate sprue 31 and is connected to the inlet on the gate sprue 31, the gate sprue 31 is mounted on the fixed mold core and the outlet of the gate sprue 31 is connected to the product molding cavity. The valve needle 34 is located inside the hot runner nozzle 35 and acts as a flow and pressure valve for the hot runner nozzle 35. The valve needle 34 is connected to the output end of the valve needle control cylinder 37. The valve needle control cylinder 37 is electrically connected to the hot runner plug 2. The valve needle hydraulic circuit connector 3 is connected to the valve needle control cylinder 37.

[0035] The mold layout adopts a single cavity design, with a gating system combining hot and cold runners. The melt enters the product molding cavity through a submarine gate in the hot and cold runners. The gating system is designed for single-cavity gating, using a submarine gate with dimensions of 6mm x 1.2mm, which facilitates automatic separation of the product and the gate during ejection. The main hot runner gate 38 has a dimension of φ7mm; the hot runner nozzle 35 has a dimension of φ6mm; and the cold runner 17 has a length of 134mm and a thickness of 6mm.

[0036] The melt enters the hot runner manifold 36 from the main inlet 38 and flows into the hot runner nozzle 35 within the manifold 36. The valve needle control cylinder 37 controls the flow rate of the hot runner nozzle 35 by extending and retracting the valve needle 34, thereby regulating the melt flow rate and pressure. The melt is injected into the cold runner 17 through the hot runner nozzle 35, passes through the submarine gate 32, and enters the gate feed shank 31 to fill the product 30.

[0037] like Figure 5 As shown, the product's demolding and ejection adopts a method of ejection by a fixed mold ejection cylinder and ejector pins. Specifically, the ejection system includes an ejection signal plug 1, an ejection oil circuit connector 6, an ejection cylinder 11, an ejector pin fixing plate 9, an ejector plate 8, a product ejector pin 15, and a runner ejector pin 16. The ejection signal plug 1 and the ejection cylinder 11 are electrically connected, the ejection oil circuit connector 6 and the ejection cylinder 11 are connected, both ends of the ejector pin fixing plate 9 are fixedly connected to the output ends of the ejection cylinder 11, the ejector pin fixing plate 9 and the ejector plate 8 are fixedly connected, the product ejector pin 15 and the runner ejector pin 16 are fixedly installed on the ejector plate 8, the product ejector pin 15 penetrates the fixed mold core and mates with the product molding cavity, and the runner ejector pin 16 is connected to a cold runner positioning stalk 33, which is fixedly connected to the outer wall of the cold runner 17.

[0038] The ejector oil connector 6 is integrated into the hot runner plate 5. During system operation, oil is supplied to the ejector cylinder 11 through the ejector oil connector 6 to push the ejector pins upward, while simultaneously enabling the ejector pin fixing plate 9 and the ejector plate 8 to work together as a whole. The through-hole layout on the ejector plate 8 is precise, corresponding one-to-one with the number of product ejector pins 15 and runner ejector pins 16, ensuring stable and fixed installation. The thrust of the ejector cylinder 11 not only ejects the product ejector pins 15 but also pushes the runner ejector pins 16, ensuring smooth demolding of the product and runner. The cold runner positioning shank 33 can easily break off the runner and also position the runner, providing reliable mechanical support and hydrodynamic control for the demolding of the cold runner 17 and the product 30.

[0039] like Figure 6As shown, the cooling system includes a moving mold water channel connector 42, a moving mold water channel 39, a fixed mold water channel connector 43, a fixed mold water channel 40, a hot runner plate water channel connector 44, and a hot runner plate water channel 41. The moving mold water channel connector 42 and the moving mold water channel 39 are connected, and the moving mold water channel 39 is installed inside the moving mold and positioned close to the product molding cavity. The fixed mold water channel connector 43 and the fixed mold water channel 40 are connected, and the fixed mold water channel 40 is installed inside the fixed mold 13 and positioned close to the product molding cavity. The hot runner plate water channel connector 44 and the hot runner plate water channel 41 are connected, and the hot runner plate water channel 41 is installed around the hot runner manifold 36.

[0040] The moving mold plate, fixed mold plate 13, and hot runner plate 5 are all cooled by φ8mm pipe water cooling. The water channels 39 and 40 of the moving mold plate are designed to surround the diaphragm 28 and product 30, ensuring uniform coverage of the diaphragm 28 and product 30 and achieving all-round cooling. The water channel 41 of the hot runner plate is designed to surround the hot runner manifold 36, ensuring that the melt entering the hot runner is cooled during mold operation.

[0041] like Figure 1 As shown, the mold in this embodiment also includes a fixed mold locking template 4, a hot runner plate 5, a support plate 7, a support column 10, a position sensor 12, a template support column 14, and a lifting module 21. The fixed mold locking template 4, the hot runner plate 5, the support plate 7, and the fixed template 13 are fixedly connected in sequence, and the support column 10 is fixedly installed on the outer wall of the hot runner plate 5. Two position sensors 12 are provided, one for detecting the position of the moving template and the other for detecting the position of the ejector plate 8. The template support column 14 is fixedly connected between the fixed template 13 and the fixed mold locking template 4. The template support column 14 is sleeved with the ejector plate 8 and the ejector fixing plate 9. The hot runner plate 5, the support plate 7, and the fixed template 13 are all fixedly connected to the lifting module 21.
