Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically referring to a high-pressure stamping die for automotive parts processing. Background Technology

[0002] Stamping dies are specialized pieces of equipment used in cold stamping processes to shape materials (metal or non-metal) into parts (or semi-finished products). Depending on their function, die construction, and material, stamping dies can be classified in various ways. In automotive plastic parts manufacturing, common types of stamping dies include injection molds, compression molds, transfer molds, and extrusion molds.

[0003] The existing high-pressure stamping dies for automotive parts processing currently have the following problems:

[0004] Existing high-pressure stamping dies for automotive parts processing lack the ability to recover and utilize molten plastic material overflowing from the cavity, resulting in insufficient compaction of the molten plastic material inside the cavity. This increases the likelihood of defects such as depressions and shrinkage cavities within the molten plastic material. Furthermore, traditional high-pressure stamping dies for automotive parts processing also lack the ability to cool and solidify the molten plastic material to be formed. Therefore, they cannot meet the current requirements for the use of high-pressure stamping dies. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a high-pressure stamping die for automotive parts processing that can recover molten plastic raw materials overflowing from the cavity, fully utilize the heat inside the recovered raw materials, and cool and shape the filled raw materials.

[0006] The technical solution adopted in this proposal is as follows: This proposal provides a high-pressure stamping die for automotive parts processing, comprising a base, a support frame, a recovery box, an injection molding mechanism, a branch-type filling mechanism, and a circulating water-cooling mechanism. The support frame is located on the upper wall of the base, the recovery box is located in the middle of the upper wall of the support frame, the injection molding mechanism is located on the support frame, the branch-type filling mechanism is located on the injection molding mechanism, and the circulating water-cooling mechanism is located on the side wall of the support frame. The injection molding mechanism includes a mating mechanism, a locking mechanism, and a filling mechanism. The mating mechanism is located on the upper wall of the recovery box, the locking mechanism is located on the mating mechanism, and the filling mechanism is located on the support frame. The branch-type filling mechanism includes an overflow mechanism and a heat preservation mechanism. The overflow mechanism is located on the mating mechanism, and the heat preservation mechanism is located on the side wall of the mating mechanism. The circulating water-cooling mechanism includes a cooling mechanism and a flow guiding mechanism. The cooling mechanism is located on the side wall of the support frame, and the flow guiding mechanism is located on the side wall of the heat preservation mechanism.

[0007] As a further preferred embodiment of the present invention, the mating mechanism includes a slide block, a slide rail, a strip groove, and a slider. The slide block is located on the upper wall of the recycling bin, the slide rail is located on the upper wall of the slide block, the strip groove is located on the inner wall of the slide rail and is through-type, the slider is symmetrically located at both ends of the slide rail and slides on the outer side of the slide rail, the mating semi-arc cylinder is located on the upper wall of the slider and is open at one end, with the openings of the mating semi-arc cylinders facing each other; the locking mechanism includes a locking plate, a bolt, and a nut. The locking plates are symmetrically located on both sides of the mating semi-arc cylinder, the bolt is through-type located between the inner walls of the locking plates and is threadedly connected to the locking plates, the nut is located on the outer side of the bolt and is threadedly connected to the bolt; the filling mechanism includes an injection channel and a forming mold. The forming mold is located on the inner wall of the mating semi-arc cylinder, the injection channel is through the mating semi-arc cylinder, and the forming mold is located on the inner wall of the support frame.

[0008] In use, initially, the nut is positioned away from the bolt. The mating semi-arc cylinder drives the molding die to be located at both ends of the slide rail. When molding of automotive parts is required, the mating semi-arc cylinder is pushed, causing the molding die to move relative to it. The mating semi-arc cylinders are in a mating state, and the molding die is brought into contact with the mating semi-arc cylinders. The bolt is inserted through and between the locking plates, and the nut is screwed into the outside of the bolt. The mating semi-arc cylinders are tightly fixed together. The mating semi-arc cylinders and the molding die are in contact with the outside of the injection channel. Molten plastic material is injected into the molding die through the injection channel. The molten plastic material enters the molding die along the injection channel and fills the molding die to form the prototype of the automotive part.

[0009] Preferably, the heat preservation mechanism includes a heat preservation groove and heat preservation copper pipes. Multiple sets of heat preservation copper pipes are installed through the side wall of the mating semi-arc cylinder. The heat preservation groove is installed on the inner wall of the mating semi-arc cylinder between the heat preservation copper pipe and the forming mold. The heat preservation groove is a through-type arrangement. The overflow mechanism includes a semi-conical cylinder, an overflow copper pipe, and a telescopic pipe. Multiple sets of overflow copper pipes are installed through the inner wall of the heat preservation copper pipe. The semi-conical cylinder is connected to the side of the overflow copper pipe near the support frame. The semi-conical cylinder is open at one end. The telescopic pipe is connected between the overflow copper pipe and the recycling box.

[0010] During use, excess molten plastic material is continuously filled into the molding mold. On the one hand, this ensures that the inside of the molding mold is fully and evenly filled, producing automotive parts plastic products with high density and strength. On the other hand, it ensures that the inside of the molding mold is completely filled, avoiding defects such as dents and shrinkage cavities caused by insufficient material in automotive parts products. To ensure the fluidity of the molten plastic material, molten plastic material is continuously injected into the support frame. Molten plastic material overflowing from the molding mold enters the semi-conical cylinder. The semi-conical cylinder discharges excess molten plastic material into the recycling box through the overflow copper pipe. The molten plastic material with temperature inside the overflow copper pipe heats the heat-insulating copper pipe. The heat-insulating copper pipe insulates the molding mold through the heat-insulating tank, ensuring the fluidity of the molten plastic material inside the molding mold and reducing the probability of the molten plastic material entering the molding mold solidifying.

[0011] Specifically, the cooling mechanism includes a cold water tank and a thermoelectric cooling fin assembly. The cold water tank is symmetrically arranged on both sides of the support frame, and the thermoelectric cooling fin assembly is installed through the inner wall of the cold water tank, with the cooling end of the thermoelectric cooling fin assembly located inside the cold water tank. The flow guiding mechanism includes a cooling arc tube, a circulating pump, an outlet hose, a return hose, and a control valve. The cooling arc tube is symmetrically arranged on the side of the insulated copper pipe away from the opposing semi-arc cylinder, and the cooling arc tube is connected to the insulated copper pipe. The circulating pump is located on the bottom wall of the cold water tank, with the pumping end of the circulating pump penetrating inside the cold water tank. The outlet hose is connected between the cooling arc tube at the bottom of the opposing semi-arc cylinder and the outlet end of the circulating pump. The control valve is connected to the upper wall of the cold water tank, and the return hose is connected between the cooling arc tube at the top of the opposing semi-arc cylinder and the control valve.

[0012] In use, excess molten plastic material inside the support frame is manually scooped into the semi-conical cylinder. The molten plastic material flows along the overflow copper pipe into the recycling tank. Then, the molten plastic material filled inside the molding die is cooled and solidified. The thermoelectric cooling unit cools the water inside the cold water tank through the cooling end. The circulating pump draws cooling water from the cold water tank through the pumping end. The cooling water enters the insulation copper pipe through the outlet hose and the cooling arc pipe at the bottom of the semi-conical cylinder. The insulation copper pipe cools the molding die through the insulation tank. The temperature of the molding die gradually decreases, which allows the molten plastic material inside to solidify and form. The water after heat exchange enters the return water hose through the cooling arc pipe at the top of the semi-conical cylinder. The return water hose discharges the water into the cold water tank for circulating cooling.

[0013] The cold water tank is equipped with a controller on its side wall.

[0014] Preferably, the controller is electrically connected to both the thermoelectric cooling fin assembly and the circulating pump.

[0015] Furthermore, the controller is model number SYC89C52RC-401.

[0016] The beneficial effects achieved by this solution using the above structure are as follows:

[0017] Compared with existing technologies, this solution adopts a dual-pipe flow guiding structure. Through the coordinated use of an injection molding mechanism, a branch-pipe filling mechanism, and a circulating water cooling mechanism, along with a mating mechanism, locking mechanism, filling mechanism, overflow mechanism, heat preservation mechanism, cooling mechanism, and flow guiding mechanism, when excess molten plastic material continues to be filled into the molding mold cavity, the molten plastic material overflowing from the injection channel can be guided into the semi-conical cylinder. The overflow copper pipe discharges the molten plastic material into a recovery tank for recycling. Under the heat conduction of the heat preservation copper pipe, the molten plastic material in the molding mold is kept warm through the heat preservation tank, reducing heat loss and ensuring... The mold cavity is completely filled with excess molten plastic material, thus avoiding defects such as dents and shrinkage cavities caused by material shortage in automotive parts. This ensures the density and strength of the automotive parts plastic products. The molten plastic material overflowing from the mold enters the semi-conical cylinder. The semi-conical cylinder discharges the excess molten plastic material into the recycling tank through the overflow copper pipe. The molten plastic material inside the overflow copper pipe heats the insulation copper pipe. The insulation copper pipe keeps the mold warm through the insulation tank, ensuring the fluidity of the molten plastic material inside the mold and reducing the chance of the molten plastic material entering the mold solidifying.

[0036] The cooling mechanism 26 includes a cold water tank 27 and a thermoelectric cooling fin assembly 28. The cold water tank 27 is symmetrically arranged on both sides of the support frame 2.

[0038] The controller 35 is electrically connected to the thermoelectric cooling chip assembly 28 and the circulating pump 31, respectively.

[0039] The controller 35 is model number SYC89C52RC-401.

[0040] In practical use, initially, the nut 14 is positioned away from the bolt 13. The mating semi-arc cylinder 10 drives the forming mold 17 to be located at both ends of the slide rail 7. When the automotive parts need to be formed, the operator manually pushes the mating semi-arc cylinder 10. The mating semi-arc cylinder 10 slides along the slide rail 7 via the slider 9, causing the forming mold 17 to move relative to each other. The mating semi-arc cylinder 10 is in a mating state, and the mating semi-arc cylinder 10 drives the forming mold 17 to be mated together. The bolt 13 is inserted through and between the locking plates 12, and the nut 14 is screwed into the outside of the bolt 13. The mating semi-arc cylinder 10 is tightly closed. The components are fixed together, and the mating semi-arc cylinder 10 and the molding mold 17 are attached to the outside of the injection channel 16. Molten plastic material is injected into the molding mold 17 through the injection channel 16. A suitable release agent is added to the molten plastic material in advance to reduce the friction between the molten plastic material and the support frame 2, the recycling box 3, the mating semi-arc cylinder 10, and the molding mold 17, thereby improving the fluidity of the molten plastic material. The molten plastic material enters the molding mold 17 along the injection channel 16 and fills the molding mold 17 to form the prototype of the automotive part.

[0041] The process of continuously filling the mold 17 with excess molten plastic material serves two purposes. First, it ensures that the mold 17 is filled fully and evenly, producing automotive parts with higher density and strength. Second, it ensures that the mold 17 is completely filled, preventing defects such as dents and shrinkage cavities caused by material shortages in automotive parts. To ensure the fluidity of the molten plastic material, molten plastic material is continuously injected into the support frame 2. The molten plastic material overflowing from the mold 17 enters the semi-conical cylinder 20. The semi-conical cylinder 20 discharges the excess molten plastic material through the overflow copper pipe 21 and the telescopic pipe 36 into the recycling box 3. The molten plastic material with temperature inside the overflow copper pipe 21 heats the heat-insulating copper pipe 24. The heat-insulating copper pipe 24 insulates the mold 17 through the heat-insulating tank 23, ensuring the fluidity of the molten plastic material inside the mold 17 and reducing the probability of the molten plastic material entering the mold 17 solidifying.

[0042] Excess molten plastic material inside the support frame 2 is manually scooped into the semi-conical cylinder 20. The molten plastic material flows into the recycling box 3 along the overflow copper pipe 21. Then, the molten plastic material filled inside the molding mold 17 is cooled and solidified. The controller 35 controls the thermoelectric cooling chip group 28 to start. The thermoelectric cooling chip group 28 cools the water inside the cold water tank 27 through the cooling end. The controller 35 controls the circulation pump 31 to start. The circulation pump 31 draws cooling water from inside the cold water tank 27 through the water pumping end. The cooling water enters the heat-insulating copper pipe 24 through the outlet hose 32 and the cooling arc pipe 30 at the bottom of the combined semi-arc cylinder 10. The heat-insulating copper pipe 24 cools the molding mold 17 through the heat-insulating tank 23. The temperature of the molding mold 17 gradually decreases, thereby solidifying the molten plastic material inside. The water after heat exchange enters the return water hose 33 through the cooling arc pipe 30 at the top of the combined semi-arc cylinder 10. The return water hose 33 discharges the water into the cold water tank 27 for circulation cooling.

[0043] After the automotive parts inside the molding die 17 are shaped, the controller 35 controls the circulating pump 31 to reverse the extraction, closes the control valve 34, and blocks and cuts off the connection between the return water hose 33 and the cold water tank 27. The circulating pump 31 then pumps the cooling water inside the insulated copper pipe 24 back into the cold water tank 27 through the outlet hose 32, which facilitates the injection of molten plastic raw materials again.

[0044] Manually rotate nut 14 to unscrew it from the outside of bolt 13. The operator pulls the mating semi-arc cylinder 10, which slides back and forth along slide rail 7 via slider 9. The back-to-back movement of the mating semi-arc cylinder 10 demolds the car parts. The operator then removes the demolded car parts from the mold 17. The above operation can be repeated for the next use.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
