Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and in particular to a device for disassembling the flow channel body parts of a plastic hollow machine head. Background Technology

[0002] A plastic blow molding machine consists of main components such as the die head, extruder, and molding machine, with the die head being a key component. The die head's flow channel components are assembled from rings of different diameters. However, when disassembling these flow channel components, the small clearance between them and the presence of high-temperature molten plastic within the channels make disassembly difficult. Furthermore, disassembly must be performed at high temperatures (above 100°C), but the die head structure limits the disassembly space. These factors contribute to the difficulty in disassembling the flow channel components, requiring significant manpower and time for each disassembly. Utility Model Content

[0003] To address the aforementioned defects or shortcomings, the purpose of this utility model is to provide a device for disassembling the flow channel body parts of a plastic hollow machine head.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A device for disassembling the flow channel body parts of a plastic hollow machine head includes: a support body for supporting the flow channel body parts of the machine head, and a disassembly mechanism cooperating with the support body. The disassembly mechanism includes: a pressing mechanism for pressing the outer flow channel body parts, and a pressing plate for pushing the inner flow channel body parts apart, wherein the pressing plate is in pressing contact with the top of the inner flow channel body parts.

[0006] A hydraulic mechanism is installed in the middle of the pressing mechanism, and the movable end of the pressing mechanism is connected to the pressing plate.

[0007] The hydraulic mechanism is a hydraulic cylinder or a jack.

[0008] The upper plate has symmetrically arranged waist-shaped holes, and the lower push rod is fixedly installed in the waist-shaped holes.

[0009] The lower push rod is a screw rod, which is fixedly installed on the upper plate by a nut, and the end of the lower push rod contacts the top of the outer flow channel part.

[0010] The support body is a hollow structure, and the inner diameter of the support body is larger than the outer diameter of the inner flow channel part.

[0011] The inner wall of the support is a smooth structure.

[0012] The lower pressure plate is a circular structure, with a diameter smaller than the outer diameter of the inner flow channel component and larger than the inner diameter of the inner flow channel component; or the lower pressure plate is a rectangular structure, with a length smaller than the outer diameter of the inner flow channel component and larger than the inner diameter of the inner flow channel component.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention provides a device for disassembling the flow channel body parts of a plastic hollow machine head. By applying different forces to the outer and inner flow channel body parts of the machine head through a support body, a pressing mechanism, and a pressing plate, the inner flow channel body parts are separated under the action of the thrust. This solves the problem of inconvenient operation when disassembling machine head flow channel body parts. Using this tooling mechanism, machine head flow channel body parts can be quickly disassembled, and the operation is convenient, saving time and effort. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0019] like Figure 1 , 2As shown, this utility model provides a device for disassembling the flow channel body parts of a plastic hollow machine head, including: a support body 8 for supporting the flow channel body parts of the machine head, and a disassembly mechanism cooperating with the support body 8. The disassembly mechanism includes: a pressing mechanism for pressing the outer flow channel body parts 7, and a pressing plate 5 for pushing the inner flow channel body parts 6 apart, the pressing plate 5 pressing against the top of the inner flow channel body parts 6. The pressing plate 5 has a circular structure, the diameter of which is smaller than the outer diameter of the inner flow channel body parts 6 and larger than the inner diameter of the inner flow channel body parts 6; or the pressing plate 5 has a rectangular structure, the length of which is smaller than the outer diameter of the inner flow channel body parts 6 and larger than the inner diameter of the inner flow channel body parts 6.

[0020] Specifically, a hydraulic mechanism 4 is installed in the middle of the pressing mechanism, and the movable end of the pressing mechanism 4 is connected to the pressing plate 5. For example, the hydraulic mechanism 4 in this invention is a hydraulic cylinder or a jack, wherein the jack can be automatic or manual hydraulic.

[0021] Preferably, the upper plate 1 has symmetrically arranged waist-shaped holes 11, and the lower push rod 3 is fixedly installed in the waist-shaped holes 11. The lower push rod 3 is a screw rod, which is fixedly installed in the upper plate 1 by a nut 2, and the end of the lower push rod 3 contacts the top of the outer flow channel part 7.

[0022] To ensure the smooth separation of the inner flow channel component 6 under pressure, the support body 8 has a hollow structure. The inner diameter of the support body 8 is larger than the outer diameter of the inner flow channel component 6, but smaller than the outer diameter of the outer flow channel component 7. Simultaneously, the inner wall of the support body 8 needs to be smooth to reduce friction and protect the inner flow channel component 6 from wear as much as possible.

[0023] The working process of this utility model is as follows:

[0024] First, install the tooling mechanism, raise the flow channel body parts with the support body 8, and make the lower push rod 3 contact or connect with the outer flow channel body parts 7.

[0025] Then the lower pressure plate 5 is placed above the inner layer part 6. The diameter of the lower pressure plate 5 is smaller than the outer diameter of the inner layer flow channel part 6 and larger than the inner diameter of the inner layer flow channel part 6.

[0026] After locking the upper plate 1 in the appropriate position with nut 2, place the hydraulic mechanism 4 in the center of the lower pressure plate 5 and press it firmly against the upper plate 1.

[0027] When in use, start the hydraulic mechanism 4, the top plate 1, push the lower pressure plate 5 downward, and the lower plate 5 pushes the inner flow channel part 6 downward until the inner flow channel part 6 is separated from the outer flow channel part 7.

[0028] When there are more flow channel parts in the machine head, this method can be used to disassemble each layer of parts in sequence.

[0029] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
