Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber reinforced plastic pipeline processing, and particularly relates to a release agent spraying device for a glass fiber reinforced plastic pipeline mold. Background Art

[0002] In the production process of FRP pipes, the mold release agent spraying operation is a crucial link. Traditional mold release agent spraying operations are usually completed manually, however, this method has many shortcomings. First, manual spraying is difficult to ensure the uniformity of the release agent distribution, and it is easy to have uneven spraying or local spraying leakage. This not only affects the smooth demoulding of the FRP pipe from the mold, but may also cause the surface quality of the pipe to deteriorate, thereby affecting the overall product quality.

[0003] To solve this problem, companies usually use repeated spraying to try to avoid product problems caused by missed spraying by increasing the number of spraying times. However, although this approach improves the demoulding success rate to a certain extent, it also leads to the problem of doubling the amount of release agent, which greatly increases production costs. In addition, repeated spraying may also cause excessive accumulation of release agent on the mold surface, which in turn has a negative impact on the service life of the mold.

[0004] Therefore, it is necessary to develop a release agent spraying device for FRP pipe molds to meet market demand. Summary of the invention

[0021] The present embodiment provides a release agent spraying device for a glass fiber reinforced plastic pipe mold, which is mainly composed of two coaxially arranged circular frames 1, each of which is formed by butting two semicircular rings 2 hinged to each other at one end, and a buckle is provided between the other ends of each two hinged semicircular rings 2 as a locking part 3, and the stability of the two hinged semicircular rings 2 after being butt-jointed to form the circular frame 1 is ensured by the buckle.

[0022] Between the two coaxial semicircular rings 2, there are several beams 4 for supporting the structure of the whole device. A wheel frame 5 is provided on the inner side of each beam 4, and several rollers 6 are installed on the inner side of the wheel frame 5. These rollers 6 can roll on the mold surface to ensure the uniformity of spraying. A driving mechanism, such as a driving motor 19, is provided on at least one wheel frame 5, which drives the rollers 6 to rotate through a transmission belt 20, so that the device can move along the mold surface.

[0023] like Figure 1 and Figure 3 As shown in , a plurality of nozzles 9 are provided at both ends of each wheel frame 5 for spraying the release agent. A hose 8 is provided in each of the two hinged semicircular rings 2, and the hose 8 is connected to all the nozzles 9 on that side to ensure that the release agent can be sprayed out evenly from the nozzles 9. Both hoses 8 are provided with interfaces 10, and both interfaces 10 are provided with branch pipes 11. A three-way switching valve 12 is provided between the two branch pipes 11 to control the flow direction of the release agent, so that the release agent input of a single hose 8 can realize the separate spraying operation at any end of the wheel frame 5. The three-way switching valve 12 is also provided with a main pipe 13, and the main pipe 13 is connected to the release agent source 22 (a container for containing the release agent), and a driving pump 14 is installed on the main pipe 13 to provide power for the flow of the release agent.

[0024] In order to improve the uniformity and adaptability of spraying, the present embodiment further provides a telescopic adjustment mechanism between each crossbeam 4 and the corresponding wheel frame 5. The telescopic adjustment mechanism adopts a scissor fork 16 structure, and the distance between the wheel frame 5 and the crossbeam 4 can be adjusted by adjusting the screw 17 and the scissor fork 16, so as to adapt to molds of different diameters. At the same time, a telescopic tube 15 connecting the hose 8 and the nozzle 9 is provided between each wheel frame 5 and the hose 8, so as to ensure that the nozzle 9 can always stably spray the release agent during the adjustment process.

[0030] Next, the driving pump 14 is turned on to allow the release agent to pass through the main pipe 13, the branch pipe 11, and the hose 8 in sequence and then be sprayed out from the nozzle 9. At the same time, the driving motor 19 is started to make the roller 6 roll on the mold surface, and the nozzle 9 sprays the release agent to achieve uniform spraying.

[0031] Finally, after the spraying is completed, the drive pump 14 and the drive motor 19 are turned off, the connection between the hose 8 and the release agent source 22 is disconnected, and the spraying device is removed.
