[0032] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0033] The present invention provides an intelligent transfer molding injection molding device suitable for ball valve manufacturing, the structure of which is as follows: Figure 1 、 Figure 2 and Figure 3 As shown, it includes key components such as base 1, connector 2, injection molding device 3, intelligent control unit 4, mold assembly 6 and auxiliary positioning mechanism. Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, the base 1 serves as the basic supporting component of the entire device, and is provided with a connector 2, which is connected to the injection molding device 3 by bolts or other fixing methods. The injection molding device 3 is configured to accommodate multiple materials and complete the injection molding process. The base 1 is also provided with an intelligent control unit 4, which is electrically connected to the injection molding device 3. Figure 5 As shown, base connector 2 is provided with positioning plate 1 5, which is connected to the injection assembly of injection molding device 3. Positioning plate 1 5 defines a positioning groove 1. Positioning groove 1 is used to accommodate upper mold plate 61 of mold assembly 6. Base 1 is also provided with hydraulic transmission device 7, which includes positioning plate 2 71. Positioning plate 2 71 defines a positioning groove 2, which is used to accommodate lower mold plate 62 of mold assembly 6.

[0035] like Figure 6 and Figure 8As shown, the upper mold plate 61 includes a fixed plate 611, which is embedded in a positioning groove 1. A plurality of guide rods 612 are provided on the side of the fixed plate 611 away from the positioning plate 1 5. A placement plate 1 613 is provided on the fixed plate 611. The guide rods 612 extend through the placement plate 1 613. An upper injection mold 614 is nested on the placement plate 1 613. The upper injection mold 614 is removable and has a molding groove 1 615 formed therein. The guide rods 612 are tilted at an angle ranging from 10° to 30°. This design enhances the stability of the mold when it is closed.

[0036] like Figure 9 and Figure 10 As shown, the lower template 62 includes a movable plate 621, which is embedded in the second positioning groove. A demoulding assembly 622 is slidably connected to the movable plate 621. The demoulding assembly 622 is connected to the hydraulic transmission device 7. A placement plate 2 623 is provided on the side of the movable plate 621 away from the second positioning plate 71. The placement plate 2 623 is slidably connected to the demoulding assembly 622. An injection lower mold 624 is nested on the placement plate 2 623. The injection lower mold 624 is provided with a shaping groove 2 625. The shaping groove 1 615 and the shaping groove 2 625 are adapted and suitable for the manufacture of two ball valves. A plurality of shaping parts 626 are slidably connected to the placement plate 2 623. The shaping parts 626 are slidably connected to the guide rod 612 and are detachable. At least a portion of the shaping parts 626 extends into the shaping groove 2 625 to assist in the molding of the workpiece. The injection molded part 11 ball valve after the mold assembly 6 is injection molded is shown as follows. Figure 11 shown.

[0037] like Figure 7 As shown, a plurality of locking tubes 6131 are provided on the placement plate 1 613, and a plurality of locking rods 6231 are provided on the placement plate 2 623. The locking tubes 6131 are connected with the locking rods 6231, and the gap between the locking tubes 6131 and the locking rods 6231 is less than 0.05 mm. This precise matching ensures high-precision alignment when the mold is closed, avoiding product defects caused by mold misalignment.

[0038] like Figure 12 As shown, an auxiliary positioning mechanism is provided on the connecting member 2, and the auxiliary positioning mechanism includes a bracket provided on the connecting member 2, a driving unit 81 is provided on the bracket, a worm 82 is provided at the output end of the driving unit 81, a worm wheel 83 is rotatably connected to the bracket, the worm wheel 83 and the worm 82 are engaged with each other, a threaded rod 84 is connected to the worm wheel 83 through a thread, a sliding block 85 is provided at one end of the threaded rod 84, a sliding bar 86 is detachably mounted on the placement plate 613, the sliding block 85 is slidably connected to the sliding bar 86, and the surface of the sliding bar 86 is coated with a lubricating coating. This design reduces friction resistance and improves the operating efficiency of the auxiliary positioning mechanism.

[0039] like Figure 1As shown, a material guiding slope 9 is provided on the base 1 and is located below the demoulding assembly 622. The inclination angle of the material guiding slope 9 ranges from 30° to 45°, so that the finished product can slide out of the mold smoothly.

[0040] The injection molding device 3 includes a feeding component and an injection component, such as Figure 4 As shown in the figure, the feed assembly features multiple feed ports, each connected to a storage container via a pipe for delivering different types of materials. A mixing chamber is located between the feed ports and the injection assembly, which is used to evenly mix the multiple materials in a preset ratio. The injection assembly includes a plunger injection unit, which is hydraulically driven to advance the molten material. A nozzle is located at its front end, connected to the injection port, for injecting the molten material into the mold.

[0041] The intelligent control unit 4 is installed on the base 1, as shown in FIG. Figure 3 It includes a central processing unit, a sensor module, and a display module. The central processing unit is electrically connected to the sensor module and the display module through circuits. The sensor module is used to collect temperature, pressure, and flow parameters in real time during the injection molding process, and the display module is used to present the operation interface and monitoring data.

[0042] The demoulding assembly 622 is provided with a plurality of ejector rods 10, such as Figure 9 As shown, the ejector rod 10 is slidably connected to the second placement plate 623 and passes through the lower injection mold 624. The end of the ejector rod 10 is coated with a wear-resistant coating, which extends the service life of the ejector rod 10. There are two ejector rods 10, symmetrically located on either side of the center of the lower injection mold 624. The ejector rods 10 are driven by a hydraulic transmission device 7 with a travel range of 0 to 200 mm. This design accommodates mold assemblies 6 of varying heights and meets diverse production needs.

[0043] During actual operation, a variety of materials are first delivered to the mixing chamber through the feeding assembly. After the mixing chamber evenly mixes the materials, the plunger injection unit pushes the molten material to the nozzle under hydraulic drive, and the nozzle injects the molten material into the mold. The intelligent control unit 4 collects the temperature, pressure and flow parameters of the injection molding process in real time through the sensor module, and presents the operation interface through the display module. The operator can adjust the injection molding parameters according to the data of the display module to ensure product quality. When the mold is closed, the upper template 61 and the lower template 62 achieve high-precision alignment through the precise cooperation of the locking tube 6131 and the locking rod 6231. The inclined design of the guide rod 612 enhances the stability of the mold when it is closed. After the injection molding is completed, the hydraulic transmission device 7 drives the demoulding assembly 622, and the ejector rod 10 pushes the finished product out of the mold. The finished product slides out along the guide slope 9, completing the entire injection molding process.

[0044] In the above-mentioned embodiment, the connection relationship, positional relationship and mutual cooperation relationship between the various components have been carefully designed to ensure the efficient operation of the equipment and the high-quality output of the product. The injection molding device 3 is tightly connected to the mold assembly 6 through the connector 2 on the base 1, and the positioning plate 1 5 and the positioning plate 2 71 respectively fix the upper template 61 and the lower template 62 to ensure that the mold remains stable during the injection molding process. The injection molding device 3 realizes the mixing and injection molding of multiple materials through the feeding assembly and the injection assembly, and the intelligent control unit 4 monitors the injection molding parameters in real time to improve production efficiency. The inclined design of the guide rod 612 enhances the stability of the mold when it is closed, and the precise cooperation between the locking tube 6131 and the locking rod 6231 ensures high precision of mold positioning. The demoulding assembly 622 pushes the finished product out of the mold through the ejector rod 10, and the guide slope 9 facilitates the sliding out of the finished product, thereby completing the entire injection molding process.

[0045] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is supplemented below with reference to a specific application scenario.

[0046] The auxiliary positioning mechanism plays an important role in the installation process of the mold assembly. When the mold assembly is installed, the drive unit 81 drives the worm 82 to rotate, the worm 82 engages with the worm wheel 83 for transmission, and the worm wheel 83 drives the threaded rod 84 to move through a threaded connection. A sliding block 85 is provided at one end of the threaded rod 84, and the sliding block 85 is slidably connected to the sliding bar 86. The lubricating coating on the surface of the sliding bar 86 is made of polytetrafluoroethylene material, and the friction coefficient is as low as 0.04, which significantly reduces the movement resistance. After the mold assembly is positioned, the operator will install the mold assembly to improve the injection molding accuracy of the mold assembly. This design ensures a smooth and reliable installation process of the mold assembly, while improving the operating efficiency of the equipment.

[0047] During the mold closing phase, the upper mold plate 61 and the lower mold plate 62 achieve high-precision alignment through the precise fit of the locking tube 6131 and the locking rod 6231. Specifically, the inner wall of the locking tube 6131 is polished, while the outer wall of the locking rod 6231 is chrome-plated, and the gap between the two is strictly controlled to within 0.05 mm. This precise fit avoids product defects caused by mold misalignment. The tilted design of the guide rod 612 further enhances the stability of the mold during closing. Its tilt angle range is set to 10° to 30°, allowing the mold to automatically correct for minor position deviations during the closing process.

[0048] During the actual ball valve injection molding process, a feed assembly first delivers multiple raw materials from separate storage containers to a mixing chamber, where the different materials are evenly mixed according to a preset ratio. A plunger-type injection unit, powered by a hydraulic system, pushes the mixed molten material into the nozzle. The connection between the nozzle and the injection port is designed as a sealed structure, effectively preventing molten material leakage while ensuring a steady flow rate of material into the first sizing groove 615 of the upper injection mold 614 and the second sizing groove 625 of the lower injection mold 624. This results in a single-piece molded part 11, reducing post-assembly steps.

[0049] The intelligent control unit 4 uses sensor modules to collect real-time temperature, pressure, and flow rate parameters during the injection molding process. Specifically, the temperature sensor is installed on the inner wall of the mixing chamber, the pressure sensor is located at the front end of the plunger injection unit, and the flow rate sensor is located at the nozzle outlet. The central processing unit dynamically adjusts the injection molding parameters based on the collected data. For example, if the molten material temperature is detected to be below the set value, the system will automatically extend the heating time or increase the heating power to ensure injection quality.

[0050] During the demolding stage, the hydraulic transmission device 7 first drives the lower mold plate 62 to move and disengage from the upper mold plate 61, allowing the injection molded part 11 to undergo preliminary demolding. During the movement of the lower mold plate 62, since the guide rod 612 is fixed, the shaping member 626 moves under the action of the guide rod 612 and completes the demolding of the injection molded part 11. The hydraulic transmission device 7 then drives the demolding assembly 622 to move the ejector rod 10 along the placement plate 2 623, ejecting the injection molded part 11 from the lower injection mold 624. Because the two ejector rods 10 are symmetrically distributed on both sides of the middle of the lower injection mold 624, when ejecting the injection molded part 11, the ejector rod 10 squeezes the connecting rod between the two ball valves instead of squeezing the ball valves themselves, thus avoiding deformation of the ball valves caused by traditional step-by-step demolding. The end of the ejector rod 10 is coated with a wear-resistant coating made of titanium nitride, which significantly increases the service life of the ejector rod 10. After being pushed out, the finished product slides out along the guide slope 9. The inclination angle range of the guide slope 9 is set to 30° to 45°, which not only ensures that the injection molded part 11 can slide out smoothly, but also avoids damage to the finished product caused by excessive inclination angle.

[0051] The first and second shaping grooves 615, 625, and the shaping piece 626 play a key role in the workpiece forming process. The shaping piece 626 is slidably connected to the guide rod 612 and is removable. The portion of the shaping piece 626 that extends into the second shaping groove 625 is made of a highly thermally conductive material, enabling rapid heat transfer and accelerating the workpiece cooling and shaping. The fit tolerance between the first and second shaping grooves 615, 625, is controlled within ±0.02 mm, ensuring the dimensional accuracy and surface quality of the ball valve product.

[0052] The coordinated work of the various components in the above steps ensures the stability and efficiency of the entire injection molding process. The base 1 tightly connects the injection molding device 3 to the mold assembly 6 through the connector 2. The positioning plate 1 5 and the positioning plate 2 71 respectively fix the upper template 61 and the lower template 62 to ensure that the mold remains stable during the injection molding process. The intelligent control unit 4 monitors the injection molding parameters in real time. The tilted design of the guide rod 612 enhances the stability of the mold when it is closed. The precise fit between the locking tube 6131 and the locking rod 6231 ensures high-precision mold positioning. The demolding assembly 622 pushes the injection molded part 11 out of the mold through the ejector rod 10. The material guide slope 9 facilitates the sliding out of the injection molded part 11, thereby completing the entire injection molding process.
