Technical Field

[0001] This utility model relates to the technical field of blow molding equipment, and in particular to an adjustable hollow blow molding die pressing device. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method, often used to produce hollow plastic utensils.

[0003] Existing blow molding equipment, such as the Chinese utility model patent CN222681738U, which describes an ejector-type disposable plastic container blow molding die, mainly consists of a first mold, a second mold, and a release plate. The first mold and the second mold work together to blow mold the plastic substrate, and the release plate assists the finished product in detaching from the first mold and the second mold after molding.

[0004] However, the existing technology and equipment still have the following problems when in use: the molds in the existing machines lack heating devices, which can easily cause the plastic temperature to be too low during blow molding, resulting in poor product quality. In addition, the existing machines are inconvenient to remove the molded products, resulting in low machine production efficiency. Utility Model Content

The two rubber pads two are respectively provided with multiple horizontal heat dissipation grooves two, and the two rubber pads four are respectively provided with multiple vertical heat dissipation grooves three. The hydraulic cylinder three provides power to drive the push plate to move back and forth. The push plate moves forward to support and eject the product, making it convenient for workers to remove the product. The rubber pads two and four increase the friction between the push plate and the product.

[0030] First, the plastic raw material is placed between the mold bodies 51. Then, hydraulic cylinder 41 and heating wire 44 are activated. Hydraulic cylinder 41 provides power, driving support bracket 43 to move closer or further apart. Support bracket 43 presses the mold body 51 together, and the mold body 51 limits the plastic, thus blowing the plastic into a specific shape.

During operation, the control panel 13 displays and controls the output force of key parts of the machine, making it convenient for workers to observe and adjust the machine. Example

[0031] In addition to Example 1, it also includes:

[0032] like Figure 8As shown, the second bracket 43 is also provided with a cavity inside. The bottom end of the second bracket 43 is provided with an oil inlet and an oil outlet.

Multiple slots are provided on the side end of the mold body 51, which are respectively adapted to the size of the multiple hollow columns of the heat conduction plate 45.

[0033] First, the plastic raw material is placed between the mold bodies 51. Then, heat-conducting oil is injected into the second support 43 to ensure that heat can evenly reach the surface of the mold body 51, resulting in a more uniform temperature distribution and improved product quality. Next, hydraulic cylinder 41 and heating wire 44 are activated. Hydraulic cylinder 41 provides power to drive the second support 43 closer together or further apart, pressing the mold body 51 together. The mold body 51 then limits the plastic, thus blowing the plastic into a defined shape. Heating wire 44 heats the mold body 51, improving the blow molding quality. After blow molding, the mold body 51 is slightly moved away. At this point, hydraulic cylinder 21 is activated, providing power to drive hydraulic cylinder 22 to move up and down. Hydraulic cylinder 22 also provides power to drive the clamping plates 23 closer together or further apart.

The rubber pad 24 increases the friction between the clamping plate 23 and the product. The heat dissipation groove of the rubber pad 24 can prevent itself from overheating and being damaged. Then the mold body 51 moves to the initial position. At this time, the hydraulic cylinder 31 is opened. The hydraulic cylinder 31 provides power to drive the push plate 32 to move back and forth. The push plate 32 moves forward to support and push out the product, making it convenient for workers to remove the product. The rubber pad 23 and rubber pad 434 increase the friction between the push plate 32 and the product. The heat dissipation groove of the push plate 32 and the heat dissipation groove of the rubber pad 23 can prevent themselves from overheating and being damaged. During the operation, the control panel 13 displays and controls the output force of the key parts of the machine, making it convenient for workers to observe and adjust the machine.

[0034] like Figures 1 to 8As shown, this utility model discloses an adjustable hollow blow molding die pressing device. During operation, plastic raw material is first placed between the die bodies 51. Then, heat-conducting oil is injected into the second support 43 to ensure heat evenly reaches the surface of the die body 51, resulting in a more uniform temperature distribution and improved product quality. Next, hydraulic cylinder 41 and heating wire 44 are activated. Hydraulic cylinder 41 provides power to drive the second support 43 closer together or further apart, pressing the die body 51. The die body 51 then limits the plastic, thus blowing the plastic into a defined shape. Heating wire 44 heats the die body 51, improving blow molding quality. After blow molding, the die body 51 moves slightly apart. At this point, hydraulic cylinder 21 is activated, providing power to drive hydraulic cylinder 22 to move up and down. The drive clamping plates 23 move closer or further apart, and hydraulic cylinders 21 and 22 work together to drive the clamping plates 23 to clamp the product, thereby demolding the product. Rubber pad 24 increases the friction between the clamping plates 23 and the product. The heat dissipation groove of rubber pad 24 can prevent itself from overheating and being damaged. Then the mold body 51 moves to the initial position. At this time, hydraulic cylinder 31 is opened. Hydraulic cylinder 31 provides power to drive the push plate 32 to move back and forth. The push plate 32 moves forward to support and push out the product, making it convenient for workers to remove the product. Rubber pads 33 and 34 increase the friction between the push plate 32 and the product. The heat dissipation groove of push plate 32 and the heat dissipation groove of rubber pad 33 can prevent themselves from overheating and being damaged. During the operation, the control panel 13 displays and controls the output force of key parts of the machine, making it convenient for workers to observe and adjust the machine.

[0035] The control panel 13, hydraulic cylinder 1 21, hydraulic cylinder 2 22, hydraulic cylinder 3 31, two hydraulic cylinders 41 and multiple heating wires 44 of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0036] The main functions achieved by this utility model are: by setting a heating and pressing device 04 to heat the machine, the plastic temperature is prevented from being too low, thus improving product quality; and by setting a demolding device 02 and an ejection device 03 to demold and eject the product, making it convenient to remove the product and improving the machine's production efficiency. This solves the existing technical problems that the molds in existing machines lack heating devices, which easily cause the plastic temperature to be too low during blow molding, resulting in poor product quality, and that existing machines are inconvenient to remove the molded products, resulting in low machine production efficiency.
