Description

Technical Field

[0001] This utility model relates to the field of PET bottle processing technology, specifically to an ejection structure based on PET bottle molding die processing. Background Technology

[0002] PET bottles are plastic bottles made of polyethylene terephthalate (PET) plastic. PET bottle molds are special molds used to manufacture PET bottles. Through specific molding processes, PET plastic raw materials are processed into PET bottles with specific shapes, sizes and functions. Ejection structures act on the PET bottle, causing the molded PET bottle to be removed from the mold cavity.

[0003] Currently, the ejection structure used in PET bottle molding die processing completes the ejection operation on the PET bottle by means of an ejector cylinder. However, the ejector cylinder is operated manually to apply force, which requires real-time monitoring, is time-consuming and labor-intensive, and easily leads to wasted time. It is impossible to time the product ejection, which affects the actual use effect and processing efficiency. Therefore, there is a need to provide an ejection structure that can solve the above-mentioned drawbacks and improve the effect. Utility Model Content

[0004] The purpose of this invention is to provide an ejection structure based on PET bottle molding die processing, thereby solving the problems mentioned in the background section. To solve the above technical problems, this invention is achieved through the following technical solution:

[0005] This utility model is an ejection structure based on PET bottle molding die processing, including:

[0006] The ejection module includes an ejector cylinder that is connected through the middle of the bottom end of the fixed mold base. A rubber pusher is fitted on the upper part of the output end of the ejector cylinder, and a collar is fitted on the middle of the outer surface of the ejector cylinder. A transverse column is fixed on one side of the outer surface of the collar, and a longitudinal column passes through one end of the transverse column. A control switch is arranged opposite to the upper part of the longitudinal column, and the control switch is electrically connected to the input end of the ejector cylinder through a wire.

[0007] Furthermore, a threaded ring is threaded to the lower part of the outer surface of the top cylinder and extends into the fixed mold base. Rectangular protrusions are evenly distributed on the outer surface of the threaded ring.

[0008] Furthermore, a support column is fixed to one side of the outer surface of the control switch, and one end of the support column is sleeved on one side of the inner wall of the movable cavity in the middle of the fixed mold base.

[0009] Furthermore, the upper end of the rubber mandrel is arc-shaped and fits against the inner wall of the mold cavity in the middle of the upper end of the fixed mold base.

[0010] Furthermore, it also includes an isolation module, which includes an isolation groove connected to one side of the bottom end of the fixed mold base, and an isolation cover is provided in the middle of the isolation groove with damping sliding.

[0011] Furthermore, a winding post is fixed at one end inside the isolation cover, and a limiting ring is wound around the outer surface of the winding post. Hole blocks are sleeved on opposite sides of one end of the limiting ring.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a top cylinder to eject PET bottles. During the ejection process, the moving end of the top cylinder moves upward in conjunction with a longitudinal column. A control switch is located above the longitudinal column. As the column moves upward, it contacts the control switch, which, when pressed, controls the top cylinder to actively close it. This upward movement of the top cylinder ensures the PET bottle is smoothly ejected from the mold cavity without constant manual monitoring, saving time and effort. It is also immediately operable, improving efficiency and effectiveness. Furthermore, the ejection uses a rubber ejector head, reducing surface damage to the PET bottle and meeting the required specifications. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-4 As shown, this utility model is an ejection structure based on PET bottle molding die processing, comprising:

[0024] The ejection module includes an ejector cylinder 11 that is connected through the middle of the bottom end of the fixed mold base. A rubber pusher head 13 is sleeved on the upper part of the output end of the ejector cylinder 11, and a collar 14 is sleeved on the middle of the outer surface of the ejector cylinder 11. A transverse column 15 is fixed on one side of the outer surface of the collar 14, and a longitudinal column 16 passes through one end of the transverse column 15. A control switch 18 is arranged opposite to the upper part of the longitudinal column 16, and the control switch 18 is electrically connected to the input end of the ejector cylinder 11 through a wire.

[0025] The top cylinder 11 applies force to the rubber mandrel 13, which is then transmitted to the PET bottle, allowing the molded PET bottle to be ejected from the mold. The collar 14 is installed and fixed to the transverse column 15, and the transverse column 15 is used to fix the longitudinal column 16. The longitudinal column 16 acts on the control switch 18, which actively controls the top cylinder 11 to ensure that the PET bottle is ejected while the braking operation is actively performed after ejection. This eliminates the need for constant human monitoring and helps improve work efficiency.

[0026] The lower part of the outer surface of the top cylinder 11 is threaded with a threaded ring 12, which extends into the fixed mold base. The outer surface of the threaded ring 12 is provided with rectangular protrusions at equal intervals.

[0027] The threaded ring 12 secures the top cylinder 11 structurally. The rectangular protrusions allow for easy gripping of the threaded ring 12, facilitating easier assembly and disassembly.

[0028] A support column 17 is fixed on one side of the outer surface of the control switch 18, and one end of the support column 17 is sleeved on one side of the inner wall of the movable cavity in the middle of the fixed mold base.

[0029] Support column 17 is used to structurally install and fix control switch 18.

[0030] The upper end of the rubber mandrel 13 is curved and fits against the inner wall of the mold cavity in the middle of the upper end of the fixed mold base.

[0031] Working principle: After the top cylinder 11 is extended into the movable cavity in the middle of the fixed mold base, multiple rectangular protrusions lock the threaded ring 12 to fix the structure of the top cylinder 11. After the PET bottle is processed and formed, the controlled top cylinder 11 acts on the rubber mandrel 13, and the force is transmitted to the formed PET bottle through the rubber mandrel 13, which can smoothly eject the bottle to complete the demolding. During the ejection operation, the output end of the top cylinder 11 moves upward in conjunction with the rubber mandrel 13, and at the same time, the longitudinal column 16 moves upward. The longitudinal column 16 is opposite to the control switch 18. After contacting the control switch 18, the control switch 18, which is opened by the pressure, actively closes the top cylinder 11. During this process, the upward stroke of the top cylinder 11 satisfies the ejection of the PET bottle.

[0032] This solution eliminates the need for constant manual monitoring, saving time and effort. It is also ready to operate immediately, thus improving efficiency and effectiveness. Furthermore, the rubber ejector head 13 reduces surface damage to PET bottles, meeting the required specifications.

[0033] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0034] The isolation module includes an isolation groove 21 connected to one side of the bottom end of the fixed mold base, and an isolation cover 22 is provided in the middle of the isolation groove 21 with damping sliding.

[0035] The isolation groove 21 is designed to accommodate the installation of the isolation cover 22. The isolation cover 22 allows wires to be laid within it, achieving the purpose of isolation and protection.

[0036] One end of the isolation cover 22 is fixed with a winding post 23, and a limiting ring 24 is wound around the outer surface of the winding post 23. Hole blocks 25 are sleeved on opposite sides of one end of the limiting ring 24.

[0037] The winding post 23 can wind and store the longer part of the conductor. It is supported by the hole block 25 and the external columnar structure. By applying an inward force to the limiting ring 24, the conductor can be limited by the contact between the inner side of the limiting ring 24 and the conductor during winding, so as to prevent it from becoming loose.

[0038] Working principle: In actual use, the wire used by the top cylinder 11 extends outward from inside the isolation cover 22. If the wire is long, the longer part of the wire can be wound around the outer surface of the winding post 23, and an external columnar structure is fitted into the hole block 25. Under the action of applying an inward pushing force, the limiting ring 24 moves inward and acts on the wound wire, which can limit the winding of the wire.

[0039] This solution not only provides insulation and protection for the conductors but also allows for conductor winding, offering versatility, enhancing the structure's functionality, and making it convenient to use.
