[0002] Ton barrel is a medium-sized bulk container, commonly known as: ton barrel, ton packaging, kiloliter barrel. It has the advantages of light weight, high strength, corrosion resistance, etc. It is widely used in chemical, pharmaceutical, food, coating, oil and fat industries. It is an essential tool for modern storage and transportation of liquid products. Blow molding technology is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while hot. After the mold is closed, compressed air is immediately introduced into the parison to inflate the plastic parison and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. The production and processing of ton barrels are mostly carried out by blow molding.

[0003] In the prior art, after the ton barrel blow molding mold is processed, when the ton barrel is separated from the mold, there are sticky edge materials on the top and bottom, which need to be manually cut off by a cutter. When cutting, the ton barrel needs to be turned over because of the edge materials on the top and bottom. However, due to the large size of the ton barrel, it is very troublesome for personnel to turn it over, which reduces the processing efficiency of the ton barrel. Utility Model Content

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model is a blow molding mold for ton barrel production, comprising a bottom plate 1, a clamping mechanism 2 is arranged in the middle of the bottom plate 1, and an adjusting mechanism 16 is arranged on the top of the bottom plate 1;

[0024] The adjusting mechanism 16 includes a transmission rod 9, which passes through and is rotatably connected to the middle of the movable plate 7. The movable plate 7 serves to connect the threaded block 6 and the mold body 14. The two sets of transmission rods 9 are fixedly connected to the mold body 14 at one end close to each other, and the two sets of transmission rods 9 are fixedly connected to the gear 10 at one end away from each other. The bottom of the gear 10 is meshed with a toothed plate 11. The toothed plate 11 moves back and forth to cause the gear 10 to rotate back and forth, thereby causing the mold body 14 fixed thereto to rotate. The toothed plates 11 are fixedly connected to the output end of the electric push rod 12, and the electric push rods 12 are fixedly connected to the middle of the rear wall of the L-shaped plate 13. The L-shaped plate 13 is fixedly connected to the upper and middle part of the front wall of the bottom plate 1. The L-shaped plate 13 can connect and fix the movable plate 7 and the electric push rod 12, so that the electric push rod 12 can work normally.

[0025] Among them, the clamping mechanism 2 includes a threaded block 6, which is threadedly connected to the left and right sides of the outer periphery of the bidirectional screw 5 respectively, and the bidirectional screw 5 is rotatably connected to the middle of the mounting groove 3. A drive motor 4 is fixedly connected to the middle of the left wall of the base plate 1. The drive motor 4 is the power component of the clamping mechanism 2. When the drive motor 4 is working, the bidirectional screw 5 will rotate, thereby making the threaded blocks 6 on both sides approach or move away from each other.

[0026] Among them, a blow molding port 15 is set in the middle of the top wall of the mold body 14, and the two groups of mold bodies 14 are symmetrically arranged about the bottom plate 1. Material is blown into the mold body 14 through the blow molding port 15 to form a ton barrel inside the mold body 14.

[0027] The output shaft of the driving motor 4 is fixedly connected to the bidirectional screw 5 , and the threaded block 6 is slidably connected to the left and right parts of the inner side of the installation groove 3 , respectively. The threaded block 6 can translate during the rotation of the bidirectional screw 5 .

[0028] Among them, the threaded blocks 6 are fixedly connected to the middle of the bottom wall of the moving plate 7, and the threaded blocks 6 and the mounting grooves 3 are arranged in the middle of the top wall of the bottom plate 1.

[0029] Among them, universal wheels 8 are arranged at the four corners of the bottom of the bottom plate 1, and the movable plates 7 are respectively located on the left and right sides of the outside of the two sets of mold bodies 14. The arrangement of universal wheels 8 can reduce the difficulty of moving the blow mold and improve its practicality.

[0030] The combined shape of the two groups of blow molding ports 15 is circular, and the movable plates 7 are clearance-matched with the bottom plate 1. During the cutting process of the ton barrel, the two groups of mold bodies 14 are slightly separated, but the ton barrel cannot fall between them.

[0031] Working principle: when it is necessary to process the ton barrel, first start the drive motor 4, the output shaft of the drive motor 4 rotates to rotate the bidirectional screw 5, so that the left and right side thread blocks 6 are close to each other, and the moving plate 7 and the mold body 14 are driven to approach each other during the movement of the thread block 6. After the two sets of mold bodies 14 are spliced, the ton barrel is blown into the mold body 14 through the blow molding port 15. After the ton barrel is formed, start the electric push rod 12, and the output end of the electric push rod 12 is extended to move the tooth plate 11 back and forth, so that the gear 10 and the transmission rod 9 rotate, and adjust the angle between the mold body 14 and the internal ton barrel finished product, so that it rotates to a height that is convenient for trimming different positions of the ton barrel. After the trimming is completed, start the drive motor 4 again to reverse the bidirectional screw 5, separate the two sets of mold bodies 14 and take out the finished product, so that the entire blow molding process is automated.
