Description

Technical Field

[0001] This utility model belongs to the field of blow molding technology, specifically relating to a blow molding machine cooling molding device. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. Thermoplastic resin is extruded or injection molded to obtain a tubular plastic preform. While still hot or heated to a softened state, it is placed in a split mold. 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. A search revealed an authorized utility model patent, publication number CN219583360U, which discloses a cooling and forming device for a blow molding machine. This utility model involves placing the product on the surface of a placement platform, then opening it to allow internal water to circulate through the water collection plate. The water is then sprayed onto the bottom through nozzles for rapid cooling. During the spraying process, a first motor drives a lead screw to rotate, causing the lead screw slider to move laterally via a lead screw and nut pair. This movement of the slider moves the water collection plate, which in turn moves the nozzles laterally, thus expanding the spraying area and increasing the cooling and forming speed of the product.

[0003] Existing cooling molding devices use traditional lead screws to drive the slider, which in turn moves the water collection plate and the nozzle. However, with a certain rotational speed, the friction of the traditional lead screw increases over time, reducing transmission efficiency and significantly decreasing the moving speed. The slow movement speed of the nozzle results in insufficient coverage of the sprayed coolant, causing some areas to fail to be adequately cooled, thus affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a blow molding machine cooling and forming device that can drive the spray head to swing back and forth at a uniform speed through a swing mechanism, so that the coolant can be distributed more quickly and evenly to cover the surface of the product, thereby shortening the molding cycle and improving production efficiency.

[0005] The specific technical solution adopted by this utility model is as follows: A blow molding machine cooling and forming device includes a forming box, a cooling box at the top of the forming box, a water pump at the top of the cooling box and connected to the cooling box, a cylinder rotatably connected to the top of the forming box, a water pipe connected to the top of the water pump, the other end of the water pipe connected to the top of the cylinder, a bend pipe connected to the front side of the cylinder, the other end of the bend pipe penetrating the interior of the forming box, a spray head connected to the bottom end of the bend pipe, and a reciprocating swing mechanism at the top of the forming box. The reciprocating swing mechanism includes a drive motor connected to the top of the forming box, a rotating ring fixedly connected to the output end of the drive motor, an arc plate connected to the inner wall of the rotating ring, a sliding groove formed inside the arc plate, a sliding block slidably connected inside the sliding groove, round rods fixedly connected to both sides of the surface of the cylinder, a U-shaped frame fitted on the surface of the two round rods, a connecting column connected to the rear side of the U-shaped frame, a universal ball connected to the rear end of the connecting column, and the universal ball rotatably connected to the front side of the sliding block.

[0006] Preferably, a lead screw is rotatably connected to the top of the sliding block, the top of the lead screw extends through to the top of the rotating ring, and the lead screw is threaded into the interior of the rotating ring.

[0007] Preferably, a limiting ring is fitted on the outer surface of both of the round rods, and the limiting ring is located on the outside of the U-shaped frame.

[0008] Preferably, the top of the molding box is provided with a track groove, and the bent tube is movably disposed inside the track groove.

[0009] Preferably, the top of the cooling tank is connected to a liquid injection pipe, and the diameter of the liquid injection pipe is five centimeters.

[0010] Preferably, an observation window is provided on the front side of the cooling box, and a scale line is provided on one side of the observation window.

[0011] Preferably, ventilation openings are provided on both sides of the molding box, and ventilation fans are installed inside the ventilation openings.

[0012] The technical effects achieved by this utility model are as follows: In this invention, when cooling blow-molded parts, the parts are placed inside a molding box. A water pump is then activated, drawing coolant from the cooling box into a cylinder via water pipes. The coolant is then delivered through the cylinder to a curved pipe and spray nozzles. Simultaneously, a drive motor operates, causing a rotating ring and an arc-shaped plate to rotate. The arc-shaped plate's rotation drives a sliding block, which in turn drives a connecting column via a universal ball joint. This rotation of the connecting column causes a U-shaped frame to rotate around the rotating ring's trajectory. Simultaneously, the U-shaped frame's rotation drives a cylindrical cylinder to rotate uniformly left and right via a round rod. This left-right rotation of the cylinder causes the curved pipe and spray nozzles to oscillate back and forth, thus quickly and efficiently spraying coolant onto the surface of the blow-molded parts. This significantly reduces the cooling time for each blow-molded part, thereby improving production line efficiency and increasing production output. Attached Figure Description

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-4As shown, a blow molding machine cooling and forming device includes a forming box 1, a cooling box 101 on the top of the forming box 1, a water pump 102 installed on the top of the cooling box 101 and connected to the cooling box 101, a cylinder 103 rotatably connected to the top of the forming box 1, a water pipe 104 connected to the top of the water pump 102, the other end of the water pipe 104 connected to the top of the cylinder 103, a bent pipe 105 connected to the front side of the cylinder 103, the other end of the bent pipe 105 penetrating the interior of the forming box 1, and a spray head 106 connected to the bottom end of the bent pipe 105. A reciprocating swing mechanism is provided on the top of the forming box 1. When cooling the blow molded part, the cooling liquid inside the cooling box 101 can be extracted by the water pump 102 and pumped into the cylinder 103 through the water pipe 104. Then, through the connection between the cylinder 103 and the bent pipe 105, the cooling liquid can be sprayed onto the surface of the blow molded part through the spray head 106 for rapid cooling.

[0017] like Figure 2 and Figure 3 As shown, the reciprocating oscillating mechanism includes a drive motor 201 connected to the top of the molding box 1. A rotating ring 202 is fixedly connected to the output end of the drive motor 201. An arc-shaped plate 203 is connected to the inner wall of the rotating ring 202. A sliding groove 204 is formed inside the arc-shaped plate 203. A sliding block 205 is slidably connected inside the sliding groove 204. Round rods 206 are fixedly connected to both sides of the surface of the cylinder 103. A U-shaped frame 207 is fitted onto the surface of the two round rods 206. A connecting post 208 is connected to the rear side of the U-shaped frame 207. A universal ball 209 is connected to the rear end of the connecting post 208. The universal ball 209 is rotatably connected to the front side of the sliding block 205. When spraying cooling liquid, it can move in tandem with the cylinder. When the drive motor 201 is in operation, it drives the rotating ring 202 to rotate. The rotating ring 202 drives the sliding block 205 to rotate around the rotation trajectory of the rotating ring 202. While the sliding block 205 is rotating, it can drive the rear end of the U-shaped frame 207 to rotate around the rotating ring 202 through the universal ball 209 and the connecting column 208. While the U-shaped frame 207 is rotating, it can drive the cylinder 103 to rotate back and forth through the round rod 206. The back and forth rotation of the cylinder 103 can simultaneously drive the bent pipe 105 and the spray head 106 to swing back and forth, ensuring that the coolant can be sprayed evenly and quickly onto the surface of the blow-molded part, avoiding local overcooling or overheating, and improving the uniformity and efficiency of cooling.

[0018] like Figure 2 and Figure 3As shown, a lead screw 3 is rotatably connected to the top of the sliding block 205. The top of the lead screw 3 extends through to the top of the rotating ring 202, and the lead screw 3 is threaded into the interior of the rotating ring 202. By rotating the lead screw 3, the lead screw 3 can drive the sliding block 205 to move away from or towards the axis of the rotating ring 202 within the sliding groove 204. When the sliding block 205 moves away from the axis of the rotating ring 202, the rotation trajectory of the connecting column 208 driving the U-shaped frame 207 can be increased, thereby driving the cylinder 103, the bent pipe 105, and... The spray head 106 has a larger swing range and spray area. When the sliding block 205 moves closer to the axis of the rotating ring 202, the swing range and spray area of ​​the spray head 106 will be reduced. When large-area cooling of certain blow-molded parts is required, the swing range of the spray head 106 can be increased to quickly reduce the temperature and improve production efficiency. Conversely, the range of the spray head 106 can be reduced to ensure concentrated cooling of local areas. This allows for optimization of the cooling effect according to specific needs, avoids waste of coolant, and ensures product quality.

[0019] like Figure 2 and Figure 3 As shown, limiting rings 4 are fitted on the outer surfaces of both round rods 206. The limiting rings 4 are located outside the U-shaped frame 207. The main function of the limiting rings 4 is to prevent the U-shaped frame 207 from shifting or deviating relative to the round rods 206. By setting the limiting rings 4 on the surface of the round rods 206 and outside the U-shaped frame 207, the U-shaped frame 207 can be prevented from detaching from the surface of the round rods 206, ensuring that the U-shaped frame 207 is always in the correct position.

[0020] like Figure 1 As shown, a track groove 5 is provided on the top of the molding box 1. The bent tube 105 is movably disposed inside the track groove 5. The track groove 5 provides a fixed movement path for the bent tube 105, ensuring that the bent tube 105 moves smoothly along the predetermined track during the spraying and cooling process of the blow molded part. This avoids friction between the bent tube 105 and the molding box 1 when the spray head 106 swings, which would affect the operation of the reciprocating swing mechanism.

[0021] like Figures 1-4 As shown, the top of the cooling box 101 is connected to a liquid injection pipe 6, which has a diameter of five centimeters. When spraying coolant onto the blow-molded parts, the operator can quickly add coolant into the cooling box 101 through the liquid injection pipe 6, thus preventing insufficient coolant in the cooling box 101 and resulting in untimely cooling of the injection-molded parts.

[0022] like Figure 1 and Figure 4As shown, an observation window 7 is provided on the front side of the cooling tank 101. A scale line is provided on one side of the observation window 7. The main function of the observation window 7 is to allow the staff to intuitively observe the liquid level of the coolant. Through the observation window 7, the height of the coolant in the cooling tank 101 can be viewed in real time to ensure that the coolant is within the appropriate liquid level range. If the coolant level is too low, the staff can replenish the coolant in time through the injection pipe 6 to avoid the decrease in cooling efficiency caused by insufficient coolant.

[0023] like Figure 1 As shown, ventilation openings 801 are provided on both sides of the molding box 1. Ventilation fans 802 are installed inside the ventilation openings 801. During the molding and cooling process, one ventilation fan 802 is used for exhaust and the other ventilation fan 802 is used for intake. This allows one ventilation fan 802 to exhaust hot air and the other ventilation fan 802 to introduce fresh air, thereby quickly reducing the temperature inside the molding box 1 and accelerating the cooling efficiency of the injection molded parts.

[0024] The working principle of this utility model is as follows: When cooling the blow-molded part, the blow-molded part is placed inside the molding box 1. Then, the water pump 102 is run. The operation of the water pump 102 will pump the coolant inside the cooling box 101 into the cylinder 103 through the water pipe 104, and then deliver it to the bent pipe 105 and the spray head 106 through the cylinder 103. At the same time, the drive motor 201 is run. The operation of the drive motor 201 will drive the rotating ring 202 and the arc plate 203 to rotate. The rotation of the arc plate 203 will drive the sliding block 205 to rotate. The rotation of the sliding block 205 will... The universal ball 209 drives the connecting column 208 to rotate. The rotation of the connecting column 208 will cause the U-shaped frame 207 to rotate around the trajectory of the rotating ring 202. While the U-shaped frame 207 rotates around the rotating ring 202, it will drive the cylinder 103 to rotate left and right at a constant speed through the round rod 206. When the cylinder 103 rotates left and right, it will drive the bent pipe 105 and the spray head 106 to swing back and forth, thereby quickly and efficiently spraying cooling liquid onto the surface of the blow-molded part. This can significantly shorten the cooling time of each blow-molded part, thereby improving the working efficiency of the production line and increasing production output.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
