When it is necessary to change to molds of different specifications to process different types of alloy steel products, since the cooling device is fixedly bound to the original mold, the original cooling device must first be completely removed from the old mold, and then the cooling device must be repositioned and installed on the new mold, the cooling pipes must be reconnected, and a sealing test must be performed. Therefore, the above problems need to be improved. Utility Model Content

A spring is provided in the spring groove. A limiting block is partially inserted into the slot at one end of the spring. A pull plate located on the top surface of the positioning seat is fixed to the top of the limiting block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a continuous cooling medium to the heat sink plate through the connection and cooperation between the cooling box and the cooling pipe, facilitating the circulation of the cooling medium within the heat sink plate and improving the stability of the cooling medium delivery, thereby achieving efficient cooling medium supply. Furthermore, through the connection and cooperation between the heat sink plate and the water injection pipe, the cooling medium is transported from the heat sink plate to the water injection pipe, facilitating quick adaptation between the water injection pipe and the mold docking post, improving the convenience of connecting the cooling pipeline to the mold, and thus achieving a quick docking function for the cooling pipeline.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figures 1 to 4This utility model discloses a mold for processing alloy steel, comprising a base plate 3, guide posts fixedly connected to the four corners of the top surface of the base plate 3, a top plate fixedly connected to the top of the guide posts, an electric push rod 2 installed in the middle of the bottom surface of the top plate, a sliding plate 1 sleeved on the four guide posts fixedly connected to the telescopic end of the electric push rod 2, two mounting plates symmetrically arranged on both sides of the top surface of the base plate 3, a bidirectional lead screw 7 rotatably connected between one side of the opposite face of the two mounting plates, a guide rod fixedly connected between the other side of the opposite face of the two mounting plates, a lower mold 4 clamped in the middle of the top surface of the base plate 3, an upper mold corresponding to the lower mold 4 clamped in the middle of the bottom surface of the sliding plate 1, a cooling box 5 fixedly connected in the middle of the bottom surface of the base plate 3, and two heat dissipation plates 10 movably arranged on both sides of the top surface of the base plate 3 on the lower mold 4; the base plate 3 is made of 304 stainless steel. The base plate 3, made of 304 stainless steel, offers excellent corrosion resistance and structural strength, providing a stable and durable mounting foundation for all components. The guide pillars and top plate are also made of 304 stainless steel, ensuring a robust structure. The guide pillars and sliding plate 1 work together to ensure stable movement of the upper mold. The electric actuator 2 uses the DYTZ series, which provides high thrust and smooth operation, ensuring continuous and reliable power for mold closing. The double-acting screw 7 and guide rod are both made of 304 stainless steel, offering good wear resistance and providing precise guidance for the movement of the heat sink 10. The lower mold 4 and upper mold are both made of 304 stainless steel, offering high temperature resistance and enabling alloy steel forming. The cooling box 5 and heat sink 10 are both made of 304 stainless steel, offering good corrosion resistance. The cooling function is prepared; the above-mentioned components together form the basic framework of the device, laying the structural foundation for the realization of mold closing, circulating cooling, and mold changing functions; symmetrical protrusions are provided on both sides of the two heat dissipation plates 10, which are respectively screwed to the bidirectional lead screw 7 and sleeved with the guide rod. One end of the bidirectional lead screw 7 is coaxially fixed to a motor 6 installed on the outer wall of one of the two mounting plates; the heat dissipation plates 10 are made of 304 stainless steel, and the protrusions on both sides cooperate with the bidirectional lead screw 7 and the guide rod, which are also made of 304 stainless steel. The motor 6 is model Y2-80M1-2. This model of motor has stable speed and sufficient power. When driving the bidirectional lead screw 7 to rotate, it can drive the heat dissipation plate 10 to move stably along the guide rod, ensuring that the heat dissipation plate 10... The water injection pipe 8 is precisely connected to the mold, improving the accuracy and efficiency of the cooling pipe connection and ensuring the subsequent delivery of cooling medium. Multiple overflow grooves 11 are connected to the outer walls and top surface of the lower mold 4. The overflow grooves 11 have an inverted L-shaped cross-section. A collection groove is opened at the lower end of the bottom plate 3, and a collection box 14 is placed in the collection groove. The lower mold 4 is made of 304 stainless steel. The overflow grooves 11 on its outer wall can guide excess material to the collection groove, avoiding material residue that corrodes the mold. The collection box 14 is made of 304 stainless steel, which is wear-resistant and easy to clean. It can collect excess material in a concentrated manner, preventing material dripping and contaminating the equipment or affecting the mold closing accuracy. At the same time, it reduces material waste, lowers subsequent cleaning costs, and improves the cleanliness of the production environment.
[0020] In this utility model, two docking pillars are symmetrically arranged on the outer walls of the lower mold 4 and the upper mold. A positioning seat is provided at the docking pillars on the bottom plate 3 and the sliding plate 1. A slot is provided on the positioning seat, and a spring groove is connected to one side of the slot. A spring is installed in the spring groove, and a limiting block 13 is partially inserted into the slot at one end of the spring. A pull plate located on the top surface of the positioning seat is fixed to the top of the limiting block 13. A snap-fit frame 12 corresponding to the slot and the limiting block 13 is fixed to one end of the docking pillar. The snap-fit frame 12 is rectangular. The docking pillar, positioning seat, and snap-fit frame 12 are all made of 304 stainless steel, ensuring a stable structure and preventing rust. The docking pillar and the positioning seat slot fit smoothly. The spring is made of 65Mn spring steel. The steel spring has good elasticity and high fatigue strength, and can stably push the limit block 13 into the snap-fit frame 12 to achieve quick positioning and fixation of the mold, which can be completed without additional tools. During disassembly, pulling the pull plate can release the fixation, simplifying the mold loading and unloading process, shortening mold changeover time, and improving operational convenience. Two cooling pipes are symmetrically arranged on both sides of the cooling box 5. The cooling box 5 has a built-in pump, and its output end is connected and fixed to four cooling pipes. Multiple parallel first circulation grooves are opened inside the heat dissipation plate 10. One end of each of the two cooling pipes passes through the mounting plate and connects to the first circulation groove of the heat dissipation plate 10. Four water injection pipes 8 connecting to the first circulation grooves extend symmetrically from both sides of the opposite surfaces of the two heat dissipation plates 10. The cooling box 5 is made of 304 stainless steel. The material is highly corrosion-resistant, and its built-in pump model is ISG50-160. This model of pump has a high head and stable flow rate, ensuring continuous flow of the cooling medium. Both the cooling pipes and the water injection pipes 8 are made of 304 stainless steel, which has good sealing performance and high temperature resistance. The cooling box 5 delivers the cooling medium to the first circulation tank of the heat dissipation plate 10 through the cooling pipes, and the water injection pipes 8 deliver the cooling medium to the mold, forming a cooling medium delivery channel to provide a stable medium supply for mold cooling and ensure cooling efficiency. Two adjacent water injection pipes 8 form a group and correspond to the docking pillars on the lower mold 4 and the upper mold, respectively. The docking pillars have docking holes for the corresponding water injection pipes 8, and quick connectors are provided in the docking holes. The lower mold 4 and the upper mold are connected by a quick connector. The mold has multiple parallel guide pipes 9, each end of which is connected to multiple quick connectors. The quick connectors are made of brass. The water injection pipe 8 and the quick connector of the docking post cooperate to achieve quick connection or separation of the cooling pipes and the mold. There is no need to disassemble the cooling box 5 and the cooling pipes. When changing the mold, only the heat sink 10 needs to be moved to switch the cooling pipe connection, which greatly shortens the cooling pipe adaptation time when changing the mold and improves production continuity. The guide pipes 9 are made of copper alloy. The copper alloy guide pipes 9 have good thermal conductivity and can quickly transfer heat from the mold, so that the cooling medium is evenly distributed in the mold. This ensures that all parts of the mold are cooled evenly, avoids deformation of alloy steel products due to uneven cooling, and improves the product molding quality.
[0021] Working principle: When using this utility model, firstly, according to the specifications of the alloy steel product to be processed, place the lower mold 4 in the middle of the top surface of the base plate 3, and place the upper mold in the middle of the bottom surface of the sliding plate 1. Directly align the docking posts on both sides of the lower mold 4 with the slots of the positioning seats on the base plate 3 and insert them. At the same time, align the docking posts on both sides of the upper mold with the slots of the positioning seats on the sliding plate 1 and insert them. A spring is provided in the spring groove on one side of the positioning seat slot. When the spring naturally extends, it pushes the limiting block 13 part into the slot. When the snap-fit frame 12 on the docking post moves with the docking post to the position of the limiting block 13, the limiting block 13 automatically snaps into the snap-fit frame under the action of the spring. Within 12, through the cooperation of the docking column, positioning seat slot, spring and limit block 13, the lower mold 4 and the base plate 3, and the upper mold and the sliding plate 1 can be precisely locked and fixed without the need to pull the pull plate. Then, the electric push rod 2 on the bottom surface of the top plate is activated. The telescopic end of the electric push rod 2 pushes the sliding plate 1 to move downward along the guide column, driving the upper mold to move closer to the lower mold 4 below and complete the mold closing, preparing for subsequent operations. After the mold closing is completed, the motor 6 installed on the outer wall of the mounting plate is activated. The motor 6 drives the bidirectional lead screw 7 to rotate. Since the protrusions on both sides of the heat sink 10 are respectively screwed to the bidirectional lead screw 7 and sleeved with the guide rod, the rotation of the bidirectional lead screw 7 drives the bidirectional lead screw 7 to rotate. The two heat sink plates 10 are moved along the guide rod towards the lower mold 4 until the water injection pipe 8 on the heat sink plate 10 is aligned with the docking hole of the docking post of the lower mold 4. The water injection pipe 8 and the quick connector in the docking hole are then inserted and disconnected. After the cooling pipeline is connected, the pump built into the cooling box 5 is started. The cooling box 5 delivers the cooling medium to the first circulation groove inside the two heat sink plates 10 through the cooling pipes on both sides, forming a cooling medium delivery channel. Then, the molten alloy steel raw material is injected into the cavity formed by the lower mold 4 and the upper mold. At the same time, the cooling box 5 continuously delivers the cooling medium to the first circulation groove of the heat sink plate 10 through the cooling pipes. The cooling medium flows into the water injection pipe 8 through the first circulation tank, enters the docking hole of the docking column through the quick connector, and finally enters the multiple parallel guide pipes 9 inside the lower mold 4 and the upper mold. When the cooling medium flows in the guide pipe 9, it exchanges heat with the mold cavity and absorbs the heat of alloy steel forming to achieve rapid cooling of the mold. After heat exchange, the cooling medium flows in the opposite direction along the guide pipe 9 and returns to the cooling box 5 through the quick connector, water injection pipe 8, first circulation tank and cooling pipe, forming a closed-loop circulation cooling system. If the amount of raw material injected is too much, the excess material will flow out along the overflow grooves 11 on both sides and the top surface of the lower mold 4 and fall into the collection box 14 in the collection groove of the bottom plate 3.When it is necessary to change to a different specification mold, first turn off the electric push rod 2 and the pump of the cooling box 5. The electric push rod 2 drives the sliding plate 1 and the upper mold to return to their original position. Then, start the motor 6 to drive the double-acting screw 7 to rotate in the opposite direction, so that the two heat dissipation plates 10 move away from the lower mold 4 along the guide rod. The quick connector of the water injection pipe 8 and the docking column will automatically separate. The connection between the cooling pipe and the old mold can be disconnected without disassembling the cooling pipe and the cooling box 5. Then, pull the pull plate on the top surface of the positioning seat. The pull plate drives the limit block 13 to compress the spring and disengage the locking frame 12 of the docking column. The locking engagement of the docking column, positioning seat, spring and limit block 13 is released. The old lower mold 4 and the upper mold are then connected. After removing the molds from the base plate 3 and sliding plate 1 respectively and replacing them with new molds of the specified specifications, the mating posts on both sides of the new mold are aligned with the slots of the corresponding positioning seats and inserted. The limiting block 13 automatically engages with the snap-fit frame 12 of the new mating post under the action of the spring, completing the fixation. Finally, the electric push rod 2 is activated to drive the upper mold and the new lower mold to close. Then, the motor 6 is activated to drive the heat sink 10 to move, allowing the water injection pipe 8 to re-insert and reconnect with the quick-connector of the mating post of the new mold. After the connection is completed, the cooling box 5 pump is activated to restore the cooling cycle. The entire mold changing process does not require disassembly and reassembly of the cooling device, significantly shortening the mold changing time and ensuring production continuity. Thus, the device is fully operational.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
