Description

Technical Field

[0001] The utility model relates to the field of rotational molding equipment, in particular to rotational molding equipment for pipeline storage tanks. Background Art

[0002] With the development of society, plastic products can be seen everywhere in production and life. As an efficient plastic molding technology, rotational molding is famous for its ability to produce large, complex and one-piece plastic products, such as complex-shaped parts in automobiles, irregular entertainment facilities commonly seen in entertainment venues, and chemical storage tanks of various specifications in the chemical industry.

[0003] The existing rotational molding equipment for pipeline storage tanks mainly fixes the mold tank body on the support frame, fixes the mold cover to one side of the tank body, introduces plastic particles at the feed port, and then installs the feed cover at the feed port to make the inside of the mold into a closed space. The open flame heating device is started to melt the plastic particles and evenly adhere to the inner wall of the mold. Finally, after the rotational molding is completed, the cooling device is turned on to cool the mold, and finally demolding is completed.

[0004] The entire process involves making storage tanks one by one, which is time-consuming, labor-intensive, and results in high production costs. Furthermore, during the cooling process, the feed cover cannot be opened due to the overall high temperature. The high temperature inside the mold dissipates slowly, resulting in a longer cooling time and lower production efficiency. Utility Model Content

[0009] By adopting the above technical solution, when the telescopic rod drives the fixed rod to move up and down, the first connecting rod and the connecting frame can swing up and down together, so that the plastic particles in the mold can be evenly rolled on the inner wall of the mold.

[0010] The utility model is further configured such that a bearing at one end of the movable frame is connected to a first motor, and a bearing at one end of the movable frame is connected to a second motor.

[0011] By adopting the above technical solution, the first motor can drive the reciprocating screw to rotate, thereby moving the sliding block on the reciprocating screw, and the second motor can drive the mold to rotate, so that the flame spraying device can evenly heat the mold.

[0015] By adopting the above technical solution, the cylinder can drive the opening and closing of the feed cover. When closed, the mold is more airtight. When the rotational molding is completed, the feed cover is opened to facilitate mold cooling.

[0016] The utility model is further configured such that a sliding rod is fixedly connected to one side of the fixing rod, and a fixing block is sleeved on the outer wall of the sliding rod.

[0017] By adopting the above technical solution, the sliding rod can limit the feed cover to move only up and down without affecting the movement of the mold.

The outer wall of the reciprocating screw 7 is sleeved with multiple sets of sliding blocks 8. The first motor 31 is started to rotate clockwise, and the reciprocating screw 7 is driven to rotate, so that the sliding block 8 installed on the reciprocating screw 7 drives the mold 9 to move toward the first motor 31. A moving frame 4 is installed on one side of the reciprocating screw 7, and a support frame 5 is installed on one end of the moving frame 4. A second motor 32 is installed on one end of the sliding block 8, and the mold 9 is installed on the output end of the second motor 32. A swing component 6 is movably installed on one side of the moving frame 4. , start the open flame heating device, the second motor 32 and the telescopic rod 2 installed on the connecting frame 63, the second motor 32 drives the mold 9 to rotate, so that the heating device can evenly heat the mold 9, and the telescopic rod 2 drives the mold 9 to shake up and down, so that the plastic particles are evenly distributed inside the mold 9. An extrusion assembly 10 is installed on one side of the swing assembly 6, and the cylinder 101 contracts inward, driving the second connecting rod 102 to move, so that the fixed block 94 and the feed cover plate 93 at one end of the second connecting rod 102 are separated from the mold cover 92, so that the internal space of the mold 9 is connected to the outside, so that the high-temperature air inside the mold 9 is discharged to the outside.

[0032] See also Figure 4 The swing assembly 6 includes a first connecting rod 61 movably mounted on the bottom of the mobile frame 4, and a fixed rod 62 is installed at one end of the first connecting rod 61. A connecting frame 63 is movably mounted on one side of the mobile frame 4, and multiple groups of flame-throwing devices are installed on one side of the connecting frame 63. The bottom of the fixed rod 62 is connected to the movable end of the telescopic rod 2. When the telescopic rod 2 drives the fixed rod 62 to move up and down, the first connecting rod 61 and the connecting frame 63 can swing up and down together, so that the plastic particles in the mold 9 can be evenly rolled on the inner wall of the mold 9.

[0033] See also Figure 1 - Figure 4 One end of the movable frame 4 is connected to a first motor 31 with a bearing, and one end of the movable frame 4 is connected to a second motor 32 with a bearing. The first motor 31 can drive the reciprocating screw 7 to rotate, so that the sliding block 8 moves on the reciprocating screw 7, and the second motor 32 can drive the mold 9 to rotate, so that the flame-spraying device can evenly heat the mold 9.

The tank body 91 and the mold cover 92 can keep the mold 9 intact, and the feed cover plate 93 can facilitate loading and heat dissipation without affecting the molding of the mold 9.

[0035] See also Figure 5 and Figure 6 The extrusion assembly 10 includes a cylinder 101 installed on one side of the fixed rod 62, and the movable end of the cylinder 101 is connected to the second connecting rod 102, and one end of the second connecting rod 102 is movably connected to the fixed block 94. The cylinder 101 can drive the opening and closing of the feed cover 93. When closed, the mold 9 is more airtight.

The slide rod 103 can limit the feed cover plate 93 to move up and down only, and will not affect the movement of the mold 9.

[0037] The working principle of the present utility model is as follows: when a storage tank needs to be made, a set of molds 9 is installed on the output end of the second motor 32, and the mold cover 92 is installed on the tank body 91, and then plastic particles are added to the inside of the tank body 91, and then the cylinder 101 is started to push one end of the second connecting rod 102 to move forward, so that the other end of the second connecting rod 102 drives the fixed block 94 on the sliding rod 103 to approach the mold cover 92, so that the feed cover plate 93 is closer and closer to the mold cover 92, until the feed cover plate 93 is tightly fitted with the mold cover 92, so that the internal space of the mold 9 becomes a closed space.

[0038] Then, the open flame heating device, the second motor 32 and the telescopic rod 2 installed on the connecting frame 63 are started. The second motor 32 drives the mold 9 to rotate so that the heating device can evenly heat the mold 9. The telescopic rod 2 drives the mold 9 to shake up and down so that the plastic particles are evenly distributed inside the mold 9.

[0039] When the rotational molding process is completed, the telescopic rod 2 drives the swing assembly 6 to return to its initial horizontal position, so that the fixed rod 62 remains flush with the support frame 5, and the cylinder 101 contracts inward, driving the second connecting rod 102 to move, so that the fixed block 94 and the feed cover plate 93 at one end of the second connecting rod 102 are separated from the mold cover 92, so that the internal space of the mold 9 is connected to the outside world, so that the high-temperature air inside the mold 9 is discharged to the outside.

[0040] Then the first motor 31 is started to rotate clockwise, and the reciprocating screw 7 is driven to rotate, so that the sliding block 8 installed on the reciprocating screw 7 drives the mold 9 to move toward the first motor 31, and finally the cooling device is started to cool and demold the mold 9 at the left end of the reciprocating screw 7.

[0041] When the first group of molds 9 leave the position of the swing assembly 6, the sliding block 8 at the right end of the reciprocating screw 7 drives the mold 9 with plastic particles placed but without the feed cover 93 installed to move toward the middle of the reciprocating screw 7. When the mold 9 moves to the middle position, the cylinder 101 is started again to install the feed cover 93 in the mold cover 92, and the rotational molding process is carried out.

[0042] The two groups of molds 9 operate simultaneously, with one group of molds 9 being heated and rotationally molded in the swing assembly 6 and the other group of molds 9 being cooled in the support frames 5 on both sides, thereby improving production efficiency.
