Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing equipment for plastic pipes, specifically a hot pressing device for plastic pipes in water heaters. Background Technology

[0002] Hot pressing is a processing method that uses heat and pressure to shape materials into specific shapes. It is widely used in the manufacturing industries of plastics and composite materials. It mainly utilizes high temperature to soften the material and then apply pressure to make it fit into a mold, and after cooling, the desired product is formed.

[0003] Currently, since most of the plastic pipes in water heaters are irregularly shaped bends, they are often hot-pressed during processing. However, after the pipes are formed and the pressure block is removed, the pipes are still embedded in the mold, making them inconvenient to remove.

[0004] Therefore, we propose to design a hot pressing molding device for water heater plastic pipes. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-3 This utility model provides a hot pressing molding device for plastic pipes of water heaters, including a base 1, with limit blocks 2 fixedly connected to both sides of the top of the base 1, a vertical plate 3 fixedly connected to one side of the top of the base 1, a first cylinder 4 fixedly connected to the center of the outer side of the vertical plate 3, and the telescopic end of the first cylinder 4 passing through the vertical plate 3 and fixedly connected to a side pressure block 5.

[0025] The two sides of the side pressure block 5 are slidably connected to the inner walls of the two limiting blocks 2, which facilitates limiting the movement direction of the side pressure block 5.

[0026] A hot-pressing fixing block 6 is fixedly connected to the top of the base 1 on the side away from the upright plate 3. A stand 7 is fixedly connected to the top of the hot-pressing fixing block 6. A second cylinder 8 is fixedly connected to the center of the top of the stand 7. The telescopic end of the second cylinder 8 passes through the stand 7 and is fixedly connected to a pressing block 9.

[0027] The hot-press fixing block 6 and the side pressing block 5 are respectively matched with the two sides of the lower pressing block 9. The hot-press fixing block 6, the side pressing block 5, the lower pressing block 9 and the bottom base 1 are in cooperation to facilitate the hot pressing of the plastic tube.

[0028] Both ends of the base 1 are provided with guide blocks 10 that are closely attached to the hot pressing fixing block 6. The bottom of the lower pressing block 9 corresponds to the top of the two guide blocks 10. The combination of the lower pressing block 9 and the guide blocks 10 facilitates the hot pressing of the plastic tube.

[0029] The base 1 is provided with an ejection mechanism 11, wherein the ejection mechanism 11 includes a cavity 111 opened inside the base 1, a motor 112 is embedded and fixedly connected to the bottom of the cavity 111, the drive shaft of the motor 112 passes through the cavity 111 and is fixedly connected to a shaped disk 113, an ejection hole 114 is opened at the top of the cavity 111, and an ejection block 115 is slidably connected to the inner wall of the ejection hole 114.

[0030] The ejector hole 114 is located at the bottom of the lower pressure block 9. The ejector block 115 passes through the ejector hole 114 and protrudes out, thereby ejecting the thermoformed plastic tube from the base 1, making it easy to remove the plastic tube. In this embodiment, a protrusion is provided in the middle of the ejector block 115, and a corresponding limit is also provided at the opening of the ejector hole 114 to prevent the ejector block 115 from coming out of the ejector hole 114 (this is for illustrative purposes only and is not shown in the figure).

[0031] In this embodiment, the bottom of the ejector block 115 is provided with an oblique angle, one side of the irregular disk 113 is matched with the oblique angle, and the oblique edge of the other side is parallel to the inclined surface of the oblique angle. During the movement, the ejector block 115 can be lifted up and then reset, and the cyclic ejection can be achieved by rotating the irregular disk 113.

[0032] In use, the first cylinder 4 and the second cylinder 8 are connected to the external air pump. First, the worker puts the heated plastic tube to be formed into the top of the guide block 10 through one end of the guide block 10. The first cylinder 4 and the second cylinder 8 are started, which respectively drive the side pressure block 5 to move towards the hot pressing fixing block 6 and drive the lower pressure block 9 to descend, and together with the base 1, they shape the plastic tube.

[0033] After the shaping is completed, the motor 112 is started to drive the shaped disk 113 to rotate. In the initial state, half of the shaped disk 113 is aligned with the bottom bevel of the ejector block 115. At this time, the top surface of the ejector block 115 is flush with the top surface of the base 1. After rotating 180°, the bevel of the other half of the shaped disk 113 is parallel to the bevel of the angle. During the rotation, the ejector block 115 can be gradually ejected, allowing it to rise along the ejector hole 114, thereby ejecting the plastic tube and making it easier for the staff to remove the plastic tube.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
