Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment technology, and more specifically, to a composite hollow blow molding equipment. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. A tubular plastic preform, obtained by extrusion or injection molding of thermoplastic resin, is placed in a split mold while still hot. After the mold is closed, compressed air is immediately introduced into the preform, causing it to inflate and adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0003] Patent application number 202121157416.6 discloses a single-station blow molding barrel hollow forming processing device, including a machine base, a mold, a clamping structure, and a blowing structure. The top side of the machine base has a first sliding groove, and the front side of the machine base has a second sliding groove. The mold includes a first template, a second template, and a dual-axis cylinder. The dual-axis cylinder is installed in the first sliding groove, and sliders are connected to the two ends of the cylinder. The first and second templates are vertically parallel, with their bottom ends extending into the first sliding groove and connecting to the sliders. A blow molding cavity is formed between the first and second templates. The clamping structure includes a toothed plate, a gear, a swing plate, a push rod, and a clamping plate. The gear is installed at the front end of the machine base and is driven by a motor. This invention makes plastic barrel production more convenient and reliable, improving the practicality of the equipment.

[0004] Regarding the aforementioned technologies, the dual-axis cylinders move and approach each other during startup, facilitating the placement of the preform in the cavity inside the molding die. Before air blowing, the top of the preform is pressed and fixed onto the air blowing pipe by a clamping plate, making it easier for the pipe wall to move into the mold. Simultaneously, air is blown into the preform through the air blowing cylinder, and the plastic bucket can be formed by cooling. However, this equipment lacks a cooling structure, which prevents the shaped product from cooling and solidifying quickly, potentially affecting the final processing effect of the product. Utility Model Content

[0005] To solve the above problems, this utility model provides a composite hollow blow molding device, which adopts the following technical solution:

[0006] A composite hollow blow molding device includes a base, with support plates fixedly installed on both sides of the base. A support frame is provided between the tops of the two support plates, and a connecting plate is provided inside the support frame. An air blowing pipe is provided at the bottom of the connecting plate, and the top of the air blowing pipe passes through the connecting plate. A connecting pipe is provided on the inner wall of the top of the support frame, and the top of the connecting pipe passes through the support frame. A second telescopic hose is connected between the bottom of the connecting pipe and the top of the air blowing pipe. A second telescopic rod is fixedly installed on the inner wall of the top of the support frame, and the end of the second telescopic rod is fixedly connected to the top of the connecting plate.

[0007] The base has a movable groove at the top, in which a screw is rotatably installed. A support block is provided on the side wall of the screw, and a movable plate is provided on the top of the support block. A second mounting box is provided on one side of the base, and a first geared motor is provided in the second mounting box. One end of the screw passes through the second mounting box and is fixedly connected to the end of the output shaft of the first geared motor. Baffles are fixedly installed on both sides of the movable plate. Two symmetrically distributed molds are slidably installed on the top of the movable plate. A blow molding cavity is provided on the opposite side of the two molds. A box is provided on the opposite side of the two molds. A cylinder is provided on the opposite side of the two baffles. The piston shafts of the two cylinders slide through the baffles on the same side and are fixedly connected to the opposite side of the box on the same side. A cooling component is provided between the molds and the box on the same side.

[0008] A first mounting plate is fixedly installed on one side of the base. The cross-section of the first mounting plate is inverted "L" shape. A robotic arm is provided at the bottom of the horizontal section of the first mounting plate. An electric gripper is provided at the end of the robotic arm. A frame is provided on the side of the base away from the vertical section of the first mounting plate. A conveyor belt is provided inside the frame. A wind-blown limiting component is provided above the frame.

[0009] By adopting the above technical solution, when the equipment is in use, the base has a conventional extrusion structure on the side away from the second mounting box. A first geared motor drives the screw to rotate, and the screw drives the support block to move within the moving groove. The support block, along with the moving plate and the mold body, moves synchronously to be positioned below the conventional extrusion structure. Then, tubular material is extruded between the two mold bodies through the extrusion structure. Subsequently, a cylinder drives the mold body on the same side to move above the moving plate, causing the two mold bodies to close. After the mold body is closed, it moves to below the support frame. Then, a second telescopic rod drives the connecting plate to move the air blowing pipe downwards, allowing the air blowing pipe to move inside the tubular product. The connecting pipe is connected to a conventional air pump, and air is blown into the mold body by the air pump, thus achieving blow molding. The product serves a specific purpose, and a cooling assembly is installed between the box and the mold. Coolant circulates between the box and the mold on the same side, which cools the product inside the mold, improving the molding efficiency. After the product is processed, the first geared motor drives the moving plate and the product to move under the first mounting plate. Then, the two molds are opened, and the electric gripper is driven by the robotic arm to move and hold the product on the conveyor belt inside the frame. The conveyor belt then transports the product away, thus unloading it. A wind-blown limiting assembly is installed above the frame to further cool the product and prevent it from tipping over under the cooling force of the wind, thus maintaining the stability of the product during movement.

[0010] Furthermore, the cooling assembly includes a first water pump fixedly installed on the inner wall of the bottom end of the housing. One end of each first water pump is connected to a first conduit. Water storage tanks are provided on opposite sides of the two molds. Sealing plates are fixedly installed on opposite sides of the two molds. The opposite sides of the two housings are fixedly connected to the opposite side of the sealing plate on the same side. The end of the first conduit away from the first water pump on the same side extends into the water storage tank on the same side. A second water pump is fixedly installed on the inner wall of the bottom end of each water storage tank. One end of each second water pump is connected to a second conduit. The second conduit is located away from the second water pump on the same side... The two tanks are connected to each other on the same side. The inner walls of the top of the two water tanks are equipped with liquid level sensors. The top of the two tanks are fixedly installed with support frames. The bottom of the two support frames is connected to the inner walls of the top of the two support frames. Multiple semiconductor cooling plates are arranged in a linear array. The top of the semiconductor cooling plates on the same side is connected to the support frames on the same side. The top of the two support frames is equipped with protective frames. Multiple heat dissipation holes are arranged in a rectangular array on the four sides of the two protective frames. Dustproof cotton is provided on the four sides of the protective frames. A power supply is provided on one side of the two tanks. A stirring assembly is provided inside the two tanks.

[0011] By adopting the above technical solution, the first water pump draws coolant from inside the box and guides it through the first conduit into a water storage tank inside the mold body on the same side. The cooperation of the two water storage tanks allows the coolant to coat the outer wall of the blow molding cavity, effectively cooling the product and improving molding efficiency. Furthermore, both water storage tanks are equipped with level sensors on their inner tops. Once the tanks are full, the second water pump draws the heated coolant from the tanks and returns it to the box body on the same side through the second conduit. The cooperation of the first and second water pumps ensures that the coolant circulates between the box body and the water storage tanks on the same side, thus maintaining the equipment's cooling efficiency. The system features two cabinets, each with a semiconductor cooling plate installed within a support frame at the top. Cool air generated by the semiconductor cooling plate is introduced into the cabinet on the same side, where it comes into contact with the coolant, maintaining its cooling effect. The heating end of the semiconductor cooling plate is located within a protective frame installed at the top of the cabinet, protecting the plate. The protective frame also has ventilation holes on its side walls to dissipate heat, ensuring continued operation of the semiconductor cooling plate. A stirring component is installed inside the cabinet to agitate the coolant, ensuring even mixing of the heated coolant with the cooling air for future reuse. A waterproof and breathable membrane is installed inside the lower section of the support frame.

[0012] Furthermore, the stirring assembly includes rotating rods rotatably mounted in two housings. Multiple sets of stirring plates arranged in a linear array are fixedly mounted on the side walls of both rotating rods. At least three stirring plates in the same set are arranged in a ring array on the side wall of the rotating rod on the same side. A first mounting box is fixedly mounted on the side of the two housings near the power supply on the same side. A second geared motor is provided in each of the first mounting boxes. The ends of the two rotating rods near the power supply on the same side pass through the first mounting box on the same side. The ends of the two rotating rods passing through the first mounting box on the same side are fixedly connected to the end of the output shaft of the second geared motor on the same side.

[0013] By adopting the above technical solution, the second geared motor drives the rotating rod on the same side to rotate, and the rotating rod drives the stirring plate on the same side to rotate. The stirring plate rotates inside the box on the same side, which can agitate the coolant and facilitate the uniform mixing of the heated coolant and the cold air, making it convenient for subsequent reuse.

[0014] Furthermore, the wind-blown limiting assembly includes two limiting plates disposed on the upper part of the frame. The lower sidewalls of the two limiting plates are provided with multiple through holes arranged in a rectangular array. An air collecting frame is fixedly installed on the opposite side of the two limiting plates. A multi-port connector is provided on the opposite side of the two air collecting frames. The opposite ends of the two multi-port connectors are connected to a first telescopic hose. A second mounting plate is provided on the opposite side of the frame. The cross-section of the second mounting plate is "L"-shaped. A first telescopic rod is provided on the inner side of the horizontal section of the second mounting plate. The first telescopic rod is fixedly connected to the opposite side of the limiting plate on the same side.

[0015] By adopting the above technical solution, when the processed product is conveyed on the conveyor belt, the first telescopic rod drives the same-side limiting plate to move towards the product. The cooperation of the two limiting plates restricts the product from deviating during conveying. The two limiting plates are provided with an air collecting frame, a multi-way connector and a first telescopic hose on opposite sides. The two first telescopic hoses are connected to the blower of the prior art. The blower generates air force, which enters the same-side multi-way connector and air collecting frame through the first telescopic hoses. The air force is discharged through the air collecting frame and then blown to the product surface through the through hole opened in the side wall of the same-side limiting plate to further cool the product. The limiting plate can also prevent the product from tipping over during conveying.

[0016] Furthermore, two symmetrically distributed grooves are provided at the top of the base. A slide rod is fixedly installed in each of the two grooves, and a slider is slidably installed in each of the two grooves. The bottom of the two sliders is provided with a placement groove that matches the slide rod on the same side. The top of the two sliders is fixedly connected to the bottom of the moving plate.

[0017] By adopting the above technical solution, when the moving plate moves, the moving plate slides with the slider in the groove on the same side, and the groove is provided with a sliding rod. The slider slides on the sliding rod on the same side. The cooperation of the slider, the sliding rod and the groove helps to maintain the stability of the moving plate.

[0018] Furthermore, stabilizing blocks are fixedly installed on both sides of the two mold bodies, and stabilizing rods are provided between the two stabilizing blocks on the same side. The two ends of the stabilizing rods slide through the stabilizing blocks on the same side and are fixedly connected to the opposite side of the two baffles.

[0019] By adopting the above technical solution, when the two molds move, the molds slide on the same side stabilizing blocks and stabilizing rods with the same side stabilizing blocks. The cooperation between the stabilizing blocks and stabilizing rods helps to limit and stabilize the molds, which is beneficial to maintaining the stability of the mold movement.

[0020] Furthermore, two symmetrically distributed positioning rods are fixedly installed on opposite sides of the two mold bodies. The two sets of positioning rods are rotationally symmetrically distributed, and positioning grooves matching the positioning rods are opened on opposite sides of the two mold bodies.

[0021] By adopting the above technical solution, positioning rods are provided on the opposite sides of the two mold bodies. When the two mold bodies are fitted together, the positioning rods engage with the positioning grooves opened on the side walls of the mold bodies. The cooperation between the positioning rods and the positioning grooves plays a positioning role, which helps to maintain the accuracy of the two mold bodies when they are fitted together.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] (1) In this utility model, by setting up a cooling component, after the two molds are closed, the product is blow-molded through the air blowing pipe. Then the coolant inside the box flows into the water storage tank opened inside the mold on the same side, which can cool the product, which is conducive to accelerating the product shaping and thus improving the processing efficiency of the equipment.

[0024] (2) In this utility model, after the product is processed, the screw is driven to rotate by the first geared motor. The screw drives the support block to move synchronously with the moving plate and the top structure to the bottom of the first mounting plate. Then, the electric gripper is driven to move by the mechanical arm. The electric gripper clamps the product and moves it to the conveyor belt. The product is transported by the conveyor belt. The top of the frame is provided with a wind-blown limiting component, which plays a role in further cooling the product and can also play a role in limiting the product from falling, which is conducive to maintaining the stability of the product during transport.

Cooling components are provided between the mold bodies 11 and the box 24 on the same side.

[0040] The cooling assembly includes a first water pump 40 fixedly installed on the inner wall of the bottom end of the housing 24. One end of each first water pump 40 is connected to a first conduit 41. Water storage tanks 37 are provided on opposite sides of the two mold bodies 11. Sealing plates 47 are fixedly installed on opposite sides of the two mold bodies 11. The opposite sides of the two housing bodies 24 are fixedly connected to the opposite side of the sealing plates 47 on the same side. The end of the first conduit 41 away from the first water pump 40 on the same side extends into the water storage tank 37 on the same side. A second water pump 42 is fixedly installed on the inner wall of the bottom end of each water storage tank 37. One end of each second water pump 42 is connected to a second conduit 43. The second conduit 43 is located away from the first water pump 40 on the same side. Two water pumps 42 extend into the same-side housing 24 at one end.

[0041] When the equipment is in use, the base 1 has a prior art extrusion structure on the side away from the second mounting box 33. The screw 3 is driven to rotate by the first reduction motor 34. The screw 3 drives the support block 35 to move in the moving groove 2. The support block 35 moves synchronously with the moving plate 7 and the mold body 11 and is placed below the prior art extrusion structure. Then, the tubular material is extruded between the two mold bodies 11 through the extrusion structure. Then, the cylinder 27 drives the mold body 11 on the same side to move above the moving plate 7, so that the two mold bodies 11 close. After the mold body 11 is closed, it moves to the bottom of the support frame 6. Then, the connecting plate 29 is driven to move the air blowing pipe 28 down by the second telescopic rod 30, and the air blowing pipe 28 moves into the inside of the tubular product. The connecting pipe 32 is connected to the prior art air blowing pump. By blowing air into the mold body 11 through the air blowing pump, the product can be blown.

[0042] The first water pump 40 draws coolant from inside the housing 24 and guides it through the first conduit 41 into a water storage tank 37 inside the mold body 11 on the same side. With the cooperation of the two water storage tanks 37, the coolant coats the outer wall of the blow molding cavity 12, effectively cooling the product and improving molding efficiency. Both water storage tanks 37 are equipped with level sensors on their inner tops. Once the water storage tanks 37 are full, the second water pump 42 draws the heated coolant from the tanks 37 and returns it to the housing 24 on the same side through the second conduit 43. The cooperation of the first and second water pumps 40 further maintains the coolant level. The coolant circulates within the same side chamber 24 and water tank 37, which helps maintain the cooling effect of the equipment. Both chambers 24 have a support frame 44 at the top, and each chamber has a semiconductor cooling plate 45. The cool air generated by the semiconductor cooling plate 45 is introduced into the same side chamber 24. The cool air comes into contact with the coolant inside the chamber 24, which helps maintain the cooling effect of the coolant. The heating end of the semiconductor cooling plate 45 is located in the protective frame 23 installed on the top of the chamber 24. The protective frame 23 can protect the semiconductor cooling plate 45, and the side wall of the protective frame 23 has heat dissipation holes, which can dissipate heat and help maintain the subsequent operation of the semiconductor cooling plate 45.

[0043] Both housings 24 are equipped with stirring components, each including a rotating rod 38 rotatably mounted within the housings 24. Multiple sets of stirring plates 39 arranged in a linear array are fixedly mounted on the sidewalls of both rotating rods 38. At least three stirring plates 39 in the same set are arranged in a ring array on the sidewall of the rotating rod 38 on the same side. A first mounting box 26 is fixedly mounted on the side of each housing 24 near the power supply 25 on the same side. A second geared motor 46 is installed inside each first mounting box 26. One end of each rotating rod 38 near the power supply 25 passes through the first mounting box 26 on the same side, and the other end of each rotating rod 38 passing through the first mounting box 26 on the same side is fixedly connected to the output shaft end of the second geared motor 46 on the same side. The second geared motor 46 drives the rotating rod 38 to rotate, which in turn drives the stirring plates 39 to rotate. The stirring plates 39, located inside the housing 24 on the same side, rotate, thus agitating the coolant and facilitating uniform mixing of the heated coolant with the cold air, making it suitable for subsequent reuse.

[0044] A first mounting plate 13 is fixedly installed on one side of the base 1. The cross-section of the first mounting plate 13 is inverted "L" shape.

[0045] After the product processing is completed, the first reduction motor 34 drives the moving plate 7 and the product to move below the first mounting plate 13. Then, the two mold bodies 11 are opened, and the electric gripper 15 is moved by the robotic arm 14. The electric gripper 15 clamps the product and moves it to the conveyor belt set inside the frame 16. The conveyor belt transports the product away, thus achieving the function of unloading. The first telescopic rod 21 drives the limit plate 20 on the same side to move towards the product. The cooperation of the two limit plates 20 restricts the deviation of the product during transportation. Furthermore, the two limiting plates 20 are provided with an air collecting frame 19, a multi-port connector 18, and a first telescopic hose 22 on opposite sides. The two first telescopic hoses 22 are connected to the existing blower. The blower generates air force, which enters the multi-port connector 18 and the air collecting frame 19 on the same side through the first telescopic hoses 22. The air force is discharged through the air collecting frame 19 and then blown to the product surface through the through hole opened on the side wall of the limiting plate 20 on the same side, thereby achieving the effect of further cooling the product. The limiting plate 20 can also prevent the product from tipping over during transportation.

[0046] The top of the base 1 has two symmetrically distributed grooves 4. A slide rod is fixedly installed in each groove 4, and a slider 36 is slidably installed in each groove 4. The bottom of each slider 36 has a placement groove that matches the slide rod on the same side. The top of each slider 36 is fixedly connected to the bottom of the moving plate 7. When the moving plate 7 moves, the moving plate 7 carries the slider 36 and slides in the groove 4 on the same side. The slider 36 slides on the slide rod on the same side. The cooperation of the slider 36, the slide rod and the groove 4 helps to maintain the stability of the moving plate 7.

[0047] Stabilizing blocks 10 are fixedly installed on both sides of the two mold bodies 11. Stabilizing rods 9 are provided between the two stabilizing blocks 10 on the same side. The two ends of the stabilizing rods 9 slide through the stabilizing blocks 10 on the same side and are fixedly connected to the opposite side of the two baffles 8. When the two mold bodies 11 move, the mold body 11 slides on the stabilizing rods 9 on the same side with the stabilizing blocks 10 on the same side. Through the cooperation of the stabilizing blocks 10 and the stabilizing rods 9, the stabilizing blocks 10 and the stabilizing rods 9 are used to limit and stabilize the mold body 11, which helps to maintain the stability of the movement of the mold body 11.

[0048] Two symmetrically distributed positioning rods are fixedly installed on opposite sides of each of the two mold bodies 11. The two sets of positioning rods are rotationally symmetrical. Positioning grooves matching the positioning rods are opened on opposite sides of the two mold bodies 11. Positioning rods are provided on opposite sides of the two mold bodies 11. When the two mold bodies 11 are fitted together, the positioning rods engage with the positioning grooves opened on the side walls of the mold bodies 11. The positioning rods and positioning grooves work together to achieve positioning, which helps to maintain the accuracy of the fitting of the two mold bodies 11.

[0049] The implementation principle of this utility model embodiment is as follows: When the equipment is in use, the base 1 is provided with a prior art extrusion structure on the side away from the second mounting box 33. The screw 3 is driven to rotate by the first reduction motor 34. The screw 3 drives the support block 35 to move in the moving groove 2. The support block 35, along with the moving plate 7 and the mold body 11, moves synchronously to be placed below the prior art extrusion structure. Then, the tubular material is extruded between the two mold bodies 11 through the extrusion structure. Subsequently, the cylinder 27 drives the mold body 11 on the same side to move above the moving plate 7, so that the two mold bodies 11 close. After the mold body 11 is closed, it moves to the bottom of the support frame 6. Then, the second telescopic rod 30 drives the connecting plate 29 to move the air blowing pipe 28 down, and moves the air blowing pipe 28 into the tubular product. The connecting pipe 32 is connected to the prior art air blowing pump, and the air blowing pump blows air into the mold body 11. This system serves as a blow molding product. A cooling assembly is provided between the housing 24 and the mold 11. Cooling fluid circulates between the housing 24 and the mold 11 on the same side, which cools the product inside the mold 11, improving molding efficiency. After product processing, the first reduction motor 34 drives the moving plate 7 and the product to move below the first mounting plate 13. Then, the two molds 11 are opened, and the electric gripper 15 is moved by the robotic arm 14. The electric gripper 15 clamps the product and moves it to the conveyor belt inside the frame 16. The conveyor belt transports the product away, thus unloading it. A wind-blown limiting assembly is provided above the frame 16 to further cool the product and prevent it from tipping over under the cooling force of the wind, thus maintaining the stability of the product during movement.

[0050] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
