Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel-plastic composite water tank production, and in particular to a mold for producing prefabricated steel-plastic composite water tanks. Background Technology

[0002] Prefabricated steel-plastic composite water tank production involves bonding steel plates and plastics using a specific process, followed by assembly into a water tank. First, the steel plates undergo pretreatment, such as rust removal and degreasing. Then, plastic powder is evenly coated onto the steel plates, which are then placed in a mold and hot-pressed to bond the plastic and steel plates tightly, forming a steel-plastic composite panel. These composite panels are cut and processed according to the design dimensions and shape of the water tank, and then assembled into a water tank using bolts and other methods. The mold plays a crucial role in the production process, determining the shape and dimensional accuracy of the steel-plastic composite panels, ensuring precise assembly, and thus producing high-quality, corrosion-resistant, and well-sealed prefabricated steel-plastic composite water tanks.

[0003] However, the current molds have the following drawbacks: Demolding: Current molds may demold slowly, relying on manual operation, resulting in high demolding strength, which can easily damage the product surface, affecting quality and slowing down production efficiency. Disassembly and Replacement: Poor mold structure design makes disassembly inconvenient, and replacement is time-consuming and labor-intensive, inconvenient for workers, and unable to quickly switch molds to adapt to different production needs. In response to this technical problem, this application proposes a mold for producing assembled steel-plastic composite water tanks. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mold for producing assembled steel-plastic composite water tanks. The aim is to enable the mold to quickly demold the formed product, thereby reducing the intensity of manual demolding, improving product quality and production efficiency, and making the mold easy to disassemble and replace, thus enhancing the convenience of the mold.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A mold for producing assembled steel-plastic composite water tanks includes a base, four columns fixedly connected to the top side of the base, a top plate fixedly connected to the top side of the four columns, a hydraulic cylinder mounted on the bottom side of the top plate, a sliding plate fixedly connected to the drive end of the hydraulic cylinder, the sliding plate slidably connected to the outer wall of the columns, a concave mold on the top side of the base, a convex mold on the bottom side of the sliding plate, a demolding assembly inside the base for ejecting the formed water tank from the concave mold, two water inlet pipes fixedly connected to the rear side of the convex mold and the front side of the concave mold, the ends of the water inlet pipes being connected to metal pipes via a disassembly assembly for disassembling the metal pipes, the metal pipes being connected to a water circulation device, and cooling chambers being provided inside both the concave mold and the convex mold.

[0006] Furthermore, the demolding assembly includes a pressure rod rotatably connected to the inside of the base via a rotating shaft, a support rod rotatably connected to the rear end of the pressure rod, and a push block slidably connected inside the base.

[0007] Furthermore, the top end of the support rod is slidably connected to the bottom side of the push block, a push plate is slidably connected inside the concave mold, and a fixing block is fixedly connected to the bottom side of the base.

[0008] Furthermore, the disassembly assembly includes a metal ring fixedly connected to the end of the water inlet pipe. A circular ring is fixedly connected to the end of the metal pipe. Two square grooves are formed on one side of the metal ring. An annular groove is formed on the inner wall of the metal ring. Two grooves are formed on the outer wall of the circular ring. The circular ring is inserted into the inside of the metal ring.

[0009] Furthermore, a telescopic rod is fixedly connected inside the groove, and an insertion rod is fixedly connected to the end of the telescopic rod. The insertion rod is inserted into the inside of the metal ring, and a lever is fixedly connected to the outer wall of the insertion rod.

[0010] Furthermore, a spring is fitted on the outer wall of the telescopic rod, with one end of the spring connected to one end of the insertion rod and the other end of the spring connected to the inside of the groove.

[0011] Furthermore, a baffle is slidably connected to one side of the groove, and one side of the baffle is inserted into the other side of the groove.

[0012] This utility model has the following beneficial effects: In this invention, a pressure rod drives a support rod to slide up and down. By allowing the support rod to slide on the bottom side of the push block, the horizontal displacement caused by the up-and-down sliding of the support rod is offset, allowing the push block to move smoothly up and down. This push block then pushes the push plate upward, causing the push plate to push the cooled and formed water tank out of the mold. This allows the mold to quickly demold the formed product. This simple and effective method reduces the intensity of manual demolding and improves product quality and production efficiency.

[0013] In this invention, by inserting a circular ring into a metal ring and making a special design to the telescopic rod so that the circular ring can still be fixed in the metal ring after the rod is detached from the metal ring, the connection between the metal pipe and the water inlet pipe can be quickly disassembled while ensuring stability. This makes the mold easy to disassemble, facilitates mold replacement by workers, and improves the convenience of the mold. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a mold for producing assembled steel-plastic composite water tanks, comprising a base 1, four columns 8 fixedly connected to the top side of the base 1, a top plate 5 fixedly connected to the top side of the four columns 8, a hydraulic cylinder 6 mounted on the bottom side of the top plate 5, a sliding plate 4 fixedly connected to the driving end of the hydraulic cylinder 6, the sliding plate 4 slidably connected to the outer wall of the columns 8, a concave mold 3 provided on the top side of the base 1, and a convex mold 7 provided on the bottom side of the sliding plate 4. The hydraulic cylinder 6 drives the sliding plate 4 to move up and down, causing the convex mold 7 to move closer to or away from the concave mold 3, thereby stamping and forming the material. (Refer to...) Figure 4 and Figure 5 Two water inlet pipes 14 are fixedly connected to the rear side of the punch 7 and the front side of the die 3. A metal pipe 15 is connected to the end of each water inlet pipe 14. The metal pipe 15 is externally connected to a water circulation device. Cooling chambers are provided inside both the die 3 and the punch 7. Cooling water is transported to the water inlet pipes 14 through the metal pipe 15 connected to the external water circulation device, allowing the cooling water to enter the cooling chambers to cool and form the stamped material. The water circulation device consists of a water pump, a water tank, and water pipes, while the metal pipe 15 is externally connected to the water pipes. (Refer to...) Figure 3 Inside the base 1, a pressure rod 2 is rotatably connected via a pivot 10. The rear end of the pressure rod 2 is rotatably connected to a support rod 11. Inside the base 1, a push block 12 is slidably connected. The top end of the support rod 11 is slidably connected to the bottom side of the push block 12. Inside the die 3, a push plate 9 is slidably connected. Inside the bottom side of the base 1, a fixing block 13 is fixedly connected. The pressure rod 2 drives the support rod 11 to slide up and down. By allowing the support rod 11 to slide on the bottom side of the push block 12, the horizontal displacement caused by the up and down sliding of the support rod 11 is offset, allowing the push block 12 to move up and down smoothly. This push block 12 then pushes the push plate 9 upward, causing the push plate 9 to push the cooled and formed water tank out of the die 3. The fixing block 13 limits the support rod 11 to prevent it from falling excessively.

[0018] Reference Figure 6 and Figure 7A metal ring 16 is fixedly connected to the end of the water inlet pipe 14, and a circular ring 17 is fixedly connected to the end of the metal pipe 15. Two square grooves 18 are formed on one side of the metal ring 16, and an annular groove 19 is formed on the inner wall of the metal ring 16. Two grooves are formed on the outer wall of the circular ring 17. The circular ring 17 is inserted into the inside of the metal ring 16. By inserting the circular ring 17 into the metal ring 16, the metal pipe 15 and the water inlet pipe 14 are initially connected together. A telescopic rod 21 is fixedly connected inside the grooves, and an insertion rod 20 is fixedly connected to the end of the telescopic rod 21. The insertion rod 20 is inserted into the inside of the metal ring 16. By inserting the insertion rod 20 into the metal ring 16, the circular ring 17 is fixed into the metal ring 16. The telescopic rod 21 employs a special design, meaning that the maximum telescopic distance of the telescopic rod 21 can only... The insertion rod 20 is just disengaged from the metal ring 16, but a portion of it remains in the annular groove 19. This ensures that even after the insertion rod 20 disengages from the metal ring 16, the annular ring 17 remains fixed within the metal ring 16. A lever 23 is fixedly connected to the outer wall of the insertion rod 20, and a spring 22 is sleeved on the outer wall of the telescopic rod 21. One end of the spring 22 is connected to one end of the insertion rod 20, and the other end is connected to the inside of the groove. A baffle 24 is slidably connected to one side of the groove, and one side of the baffle 24 is inserted into the other side of the groove. The lever 23 disengages the insertion rod 20 from the metal ring 16, and the spring 22 keeps the insertion rod 20 pressed against the metal ring 16. At the same time, the baffle 24 limits the lever 23 to prevent it from moving accidentally and causing the insertion rod 20 to disengage from the metal ring 16.

[0019] Working principle: First, the concave mold 3 and the convex mold 7 are fixed to the base 1 and the slide plate 4 respectively using bolts and other fasteners. Then, the metal pipe 15 of the external water circulation equipment is connected to the water inlet pipe 14. When it is necessary to connect the metal pipe 15 and the water inlet pipe 14, press the lever 23 to retract part of the insert rod 20 into the groove. This part refers to the part of the insert rod 20 that is inserted into the metal ring 16. Then, align the insert rod 20 with the square groove 18, and then insert the circular ring 17 into the metal ring 16. After insertion, release the lever 23 to allow the spring to spring back. Spring 22 pushes the insertion rod 20 tightly against the inside of the annular groove 19. Then, rotating the ring 17 causes the insertion rod 20 to rotate along the annular groove 19 until the insertion rod 20 rotates into the metal ring 16. Then, sliding baffle 24 causes one side of baffle 24 to insert into the groove to limit the position of the lever 23, preventing the lever 23 from moving accidentally and causing the insertion rod 20 to disengage from the metal ring 16. This completes the connection between the metal pipe 15 and the water inlet pipe 14. When it is necessary to disassemble the metal pipe 15 and the water inlet pipe 14, simply repeat the above process in reverse. The process is straightforward and will not be elaborated here. Next, the heated material is poured into the die 3. The hydraulic cylinder 6 is activated to drive the slide plate 4 downwards, causing the punch 7 to approach the die 3 and stamp the material. Cooling water is then transported to the metal pipe 15 via a water circulation system, and then to the water inlet pipe 14, allowing the cooling water to enter the cooling chamber and cool the stamped material. The hydraulic cylinder 6 is then activated to drive the slide plate 4 upwards, causing the punch 7 to disengage from the die 3. The operator can then use the foot pedal 2 to move the front end of the pressure rod 2 downwards, causing the pressure rod 2 to drive the support rod 11 upwards. As the support rod 11 moves upwards, one end of the support rod 11 slides against the bottom side of the push block 12, thus offsetting the horizontal displacement caused by the upward and downward sliding of the support rod 11. This allows the push block 12 to move smoothly up and down, pushing the push plate 9 upwards, causing the push plate 9 to push the cooled water tank out of the die 3, thus completing the demolding process.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
