Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine accessories, in particular to a barrel structure used for blow molding equipment. Background Art

[0002] An injection molding machine is a molding device that uses a plastic molding mold to make thermoplastic plastics or thermosetting plastics into plastic products of various shapes. The screw barrel is an important component of the injection molding machine, which can transport, compact, melt, stir and pressurize the plastic inside the screw barrel. The plastic is melted because a heating device is provided on it.

[0003] When installing the heating device on the screw barrel, it is generally done by fixing the heating device with a flange to the flange set on the outside of the screw barrel with bolts, or fixing the heating device to the outside of the screw barrel with a component like a cable tie. When disassembling the heating device on the outside of the screw barrel, it is necessary to open the bolts or cable ties with great force, which is a laborious operation. In addition, since the fixed components on the heating device are in a high-temperature area for a long time, the bolts or cable ties on them are more difficult to disassemble. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, the barrel structure for the blow molding equipment includes a barrel body 1, and heating rings 2 for heating the raw materials inside the barrel body 1 are equidistantly installed on the outer side of the barrel body 1, and the heating rings 2 are arranged in two semicircular shapes in contact with each other, and the heating rings 2 are sleeved on the outer side of the barrel body 1, and fixed blocks 3 are symmetrically fixedly installed in the middle of both ends of the heating ring 2, and a positioning hole 4 is opened in the middle of the fixed block 3, and a mounting block 5 is fixedly installed at a position on the outer side of the barrel body 1 corresponding to one side of the fixed block 3, and a sliding hole 6 is opened in the middle of the mounting block 5, and a positioning rod 7 is slidably installed inside the sliding hole 6, and the positioning rod 7 can slide into the internal setting of the positioning hole 4.

[0022] like Figures 1 to 5 As shown, limit rings 8 are fixedly installed on the outer side of the barrel body 1 at the positions on both sides corresponding to the heating ring 2, and the inner circle of the limit ring 8 is provided with a mounting bevel 9.

[0023] When the heating ring 2 is sleeved on the outside of the barrel body 1, the heating ring 2 is installed between the two limiting rings 8. The setting of the installation bevel 9 can conveniently clamp the heating ring 2 between the two limiting rings 8 to locate the installation position of the heating ring 2.

[0024] like Figures 1 to 5 As shown, a mounting frame 10 is fixedly installed on the outer side of the barrel body 1 at positions corresponding to both sides of the heating ring 2, a rotating rod 11 is rotatably installed in the middle of the mounting frame 10, a fixing ring 12 is fixedly installed at one end of the rotating rod 11, a connecting rod 13 is eccentrically rotatably installed on the side of the fixing ring 12 away from the rotating rod 11 through an axle pin, and the end of the connecting rod 13 away from the fixing ring 12 is rotatably connected to the positioning plug rod 7 through an axle pin.

[0025] By driving the rotating rod 11 to rotate, and then driving the fixing ring 12 to rotate, one end of the connecting rod 13 connected to the rotating fixing ring 12 will rotate, and the other end will make a linear motion, thereby driving the positioning rod 7 inside the sliding hole 6 of the mounting block 5. The positioning rods 7 on both sides of the heating ring 2 can be inserted into the positioning holes 4 in the fixing blocks 3 at both ends of the heating ring 2 to fix the position of the heating ring 2. Conversely, the positioning rods 7 can be slid out of the positioning holes 4 in the fixing blocks 3 to remove the heating ring 2.

[0026] like Figures 1 to 5 As shown, one end of the positioning rod 7 away from the connecting rod 13 is provided with a chamfer 14 .

[0027] It is convenient to slide the positioning rod 7 into the positioning hole 4.

[0028] like Figures 1 to 5 As shown, a knob 15 is fixedly mounted on one end of the rotating rod 11 away from the fixing ring 12 .

[0029] It is convenient for people to rotate the rotating rod 11.

[0030] like Figures 1 to 5 As shown, a tension spring 16 is fixedly installed on the outer ring of the fixing ring 12 , and one end of the tension spring 16 away from the fixing ring 12 is fixedly connected to the top of the inner wall of the mounting frame 10 .

[0031] When the positioning rod 7 is inserted into the positioning hole 4 , the tension spring 16 will continue to pull the outer ring of the fixing ring 12 , and will keep the positioning rod 7 continuously inserted into the positioning hole 4 , thereby preventing the heating ring 2 from falling off.

[0032] The utility model provides a barrel structure for blow molding equipment, and the specific working principle is as follows:

[0033] When the device is in use, the two heating rings 2 are tightly sleeved on the outside of the barrel body 1, and the fixing block 3 is placed corresponding to the mounting block 5. The rotating rod 11 is driven to rotate by turning the knob 15, and then the fixing ring 12 is driven to rotate. One end of the connecting rod 13 connected to the rotating fixing ring 12 will rotate, and the other end will make a linear motion, thereby driving the positioning rod 7 inside the sliding hole 6 of the mounting block 5. The positioning rods 7 on both sides of the heating ring 2 can be inserted into the positioning holes 4 in the fixing blocks 3 at both ends of the heating ring 2 to fix the position of the heating ring 2. At this time, the tension spring 16 will continue to pull the outer ring of the fixing ring 12, and will keep the positioning rod 7 continuously inserted in the positioning hole 4 to prevent the heating ring 2 from falling off;

[0034] When the heating ring 2 needs to be disassembled, the reverse rotation knob 15 drives the rotating rod 11 to rotate in the reverse direction, and then drives the fixing ring 12 to rotate in the reverse direction. The connecting rod 13 connected to the rotating fixing ring 12 will pull the positioning rod 7 to slide out of the positioning hole 4 in the fixing block 3, and the heating ring 2 can be removed.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
