Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a PPSU high-temperature material granule molding mold. Background Technology

[0002] PPSU (polyphenyl sulfone) is a high-performance thermoplastic with excellent heat resistance, chemical resistance and mechanical properties. It has a high melting temperature, low fluidity, is sensitive to moisture, and is difficult to process.

[0003] Among them, announcement number CN214214659U discloses an injection mold, including a base plate, a base, a support seat, an upper mold, a fixing plate, a mounting plate, a fixing seat, and an injection pipe. This utility model, through the setting of a fixing rod and a spring, allows the user to fix the external injection pipe for thermoplastic plastic to the fixing seat via a threaded rod, thus facilitating the injection of thermoplastic plastic into the inner cavity of the injection mold frame through the injection pipe and the support seat. Then, the user pushes the mounting plate downwards using a press, which in turn moves the fixing plate, which in turn moves the upper mold. The movement of the upper mold causes the support to fit against the top of the injection mold frame, thus achieving mold closing. The user then injects thermoplastic plastic into the inner cavity of the injection mold frame through the injection pipe and the support seat. Simultaneously, as the upper mold moves, it slides back onto the surface of the fixing rod and compresses the spring. The spring design allows the return pin to close with the angled ejector, thus protecting the angled ejector from damaging the front mold.

[0004] To facilitate the cooling and shaping of the internal products, the device is equipped with two sets of heat dissipation chambers. However, in actual use, since the heat dissipation chambers are only located on both sides of the support, the heat dissipation area is limited, and it is impossible to dissipate the temperature inside the product and mold in time. Especially when injection molding large or complex parts, the heat generated by the injection mold frame and support cannot be dissipated in time, which will lead to a longer cooling time for the plastic, affecting production efficiency. It may also affect the molding quality of the plastic due to excessive temperature, resulting in defects such as deformation and shrinkage.

[0005] Therefore, it is necessary to invent a PPSU high-temperature material particle molding die to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a PPSU high-temperature material particle molding die to solve the problem that the heat dissipation column cannot dissipate the heat generated by the injection mold frame and support seat in a timely manner, thus affecting the product preparation efficiency.

After the material is injected into the product groove between the fixed mold and the moving mold, the heat dissipation fins quickly dissipate the temperature of the product and the mold surface. At the same time, the cooling water inside the cooling pipe quickly cools the mold, so that the heat inside the mold can be dissipated quickly, improving the product molding efficiency and product quality.

[0014] By adopting the above technical solution, the micro pump draws water into the inside of the outlet pipe, and then delivers it to the inside of the branch pipe. The manifold is used to collect the cooling water and return it to the inside of the storage tank through the inlet pipe.

[0015] Optionally, multiple sets of cooling pipes are fixedly connected between the distributor pipe and the collector pipe, and the cooling pipes are fixedly connected to the heat dissipation fins.

[0016] By adopting the above technical solution, cooling water is distributed to the interior of multiple sets of cooling pipes through the distribution pipes, and the cooling pipes and heat dissipation fins work together to dissipate heat from the mold.

[0017] Optionally, a controller is fixedly installed on the rear side of the equipment bracket, and a conduit is fixedly connected to the rear surface of the fixed mold, with the rear end of the conduit fixedly connected to the surface of the controller.

[0018] Optionally, a heating copper wire is fixedly connected inside the mold at a position on the side of the product groove, and the rear end of the heating copper wire passes through a conduit and is fixedly connected to the controller.

[0019] By adopting the above technical solution, the controller is used to control the heating copper wire to heat the fixed mold and increase the temperature of the fixed mold.

[0020] Optionally, two sets of linear guide rails are fixedly connected to the front and rear sides of the inner walls on the left and right sides of the equipment bracket, and two sets of positioning blocks are fixedly connected to the front and rear sides of the moving mold, with the positioning blocks slidably connected to the linear guide rails.

[0024] 2. This utility model utilizes a controller to heat the fixed mold using heating copper wires during the feeding process, thereby increasing the temperature of the fixed mold and effectively improving the fluidity of the material in the product tank. This allows the material to quickly fill the entire product tank, increasing the feeding speed, reducing product defects, and improving the product qualification rate. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1 to 3 The PPSU high-temperature material granule molding die shown includes a device support 1. A fixed mold 13 and a moving mold 14 are provided on the inner side of the device support 1. An installation groove 11 is opened on the left wall of the device support 1. An installation frame 12 is fixedly connected inside the installation groove 11. The fixed mold 13 is fixedly installed on the right side of the installation frame 12. A hydraulic cylinder 15 is fixedly installed on the right side of the device support 1. The left end of the piston rod in the hydraulic cylinder 15 is fixedly connected to the moving mold 14. Two sets of linear guide rails 17 are fixedly connected to the front and rear sides of the inner walls of the left and right sides of the device support 1. Two sets of positioning blocks 16 are fixedly connected to the front and rear sides of the moving mold 14. The positioning blocks 16 are slidably connected to the linear guide rails 17.

[0035] A product groove is provided between the fixed mold 13 and the moving mold 14. During the injection molding process, the moving mold 14 is first pushed to the left by the hydraulic cylinder 15 so that it fits tightly with the fixed mold 13. Then, the material is injected into the product groove between the fixed mold 13 and the moving mold 14 to cool and solidify the material. After solidification is completed, the hydraulic cylinder 15 pulls the moving mold 14 to the right. After moving to the right end, the product is pushed down by the ejector rod inside the moving mold 14 to complete the unloading.

[0036] Meanwhile, as the moving mold 14 moves, it causes the positioning block 16 to slide left and right on the surface of the linear guide rail 17, thereby improving the stability of the moving mold 14 during the movement.

[0037] See Figure 1 , Figure 4 and Figure 5A heat dissipation assembly is provided on the left side of the fixed mold 13. The heat dissipation assembly includes heat dissipation fins 131, a water storage tank 2, a micro pump 21, an outlet pipe 22, a branch pipe 23, an inlet pipe 24, a collector pipe 25, and a cooling pipe 26. The heat dissipation fins 131 are fixedly connected to the left side surface of the fixed mold 13. The water storage tank 2 is fixedly installed on the left side surface of the equipment bracket 1. The micro pump 21 is fixedly installed on the left side of the upper end of the water storage tank 2. The inlet of the micro pump 21 extends to the bottom of the water storage tank 2. The lower end of the outlet pipe 22 is fixedly connected to the outlet of the micro pump 21. The branch pipe 23 is fixedly connected to the upper end of the outlet pipe 22. The lower end of the inlet pipe 24 is fixedly connected to the right side of the upper end of the water storage tank 2. The collector pipe 25 is fixedly connected to the upper end of the inlet pipe 24. Multiple sets of cooling pipes 26 are fixedly connected between the branch pipe 23 and the collector pipe 25. The cooling pipes 26 are fixedly connected to the heat dissipation fins 131.

[0038] In addition, after the material is injected into the product tank, the heat dissipation fins 131 will dissipate the heat inside the product and the mold to the outside. At the same time, the micro pump 21 is started. The micro pump 21 pumps the cooling water inside the water storage tank 2 to the inside of the cooling pipe 26 through the water outlet pipe 22 and the diversion pipe 23. As the water flows through the inside of the cooling pipe 26, it quickly carries away the heat dissipated by the heat dissipation fins 131, effectively improving the product cooling speed, facilitating rapid cooling and shaping of the product, and improving product production quality and production efficiency.

[0039] After the material has cooled and solidified, the micro pump 21 is turned off, so that the cooling water stops being delivered to the interior of the cooling pipe 26. At this time, the cooling water remaining inside the cooling pipe 26 will flow back to the interior of the water storage tank 2 through the manifold 25 and the inlet pipe 24, thus avoiding the presence of residual cooling water inside the cooling pipe 26.

[0040] See Figure 2 , Figure 4 and Figure 6 A controller 134 is fixedly installed on the rear side of the equipment bracket 1. A wire conduit 133 is fixedly connected to the rear surface of the fixed mold 13. The rear end of the wire conduit 133 is fixedly connected to the surface of the controller 134. A heating copper wire 132 is fixedly connected inside the fixed mold 13 at the side of the product groove. The rear end of the heating copper wire 132 passes through the wire conduit 133 and is fixedly connected to the controller 134.

[0041] It should be added that, due to the low fluidity of PPSU material, the fluidity of the material will be further reduced when the mold temperature is low during the injection process. Therefore, during the material feeding process of the molding mold, the heating copper wire 132 is activated by the controller 134 to heat the fixed mold 13, increase the surface temperature of the fixed mold 13, and continue to heat during the feeding process. This allows the PPSU material to be injected at a higher temperature, effectively improving the fluidity of the PPSU material, making it easier to fill the product groove and avoid gaps that affect product quality. After the injection is completed, the heating copper wire 132 can be turned off by the controller 134.

[0042] The working principle of this utility model is as follows: After the material is loaded, the heat dissipation fins 131 are used to quickly remove the heat from the surface of the product and the mold. At the same time, the micro pump 21 draws cooling water into the interior of the cooling pipe 26. The cooling water inside the cooling pipe 26 quickly removes the heat dissipated by the heat dissipation fins 131, thereby rapidly dissipating the heat inside the mold, improving product molding efficiency and product quality. During the loading process, the controller 134 is used to control the heating copper wire 132 to heat the fixed mold 13, increasing the temperature of the fixed mold 13, thereby effectively improving the fluidity of the material in the product slot, allowing the material to quickly fill the entire product slot, increasing the loading speed, reducing product defects, and improving the product qualification rate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
