[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] like Figure 1-3 As shown, the utility model proposes a pouring mechanism for glass fiber reinforced plastic grating processing, comprising a batching kettle 1 for mixing raw materials, and a pouring material box 2 is arranged on one side of the batching kettle 1;

[0026] The transmission mechanism includes a material transfer pump 31 arranged at the bottom of the batching kettle 1 and a feed end seat 33 arranged on the casting material box 2. A transmission channel is built between the material transfer pump 31 and the feed end seat 33 through a pipeline 32;

[0027] The pipe 32 is a flexible structure, and the other end of the pipe 32 is inserted into the slot of the feed end seat 33. When the casting box 2 moves, the pipe 32 can be displaced and deformed accordingly to prevent the normal movement of the casting box 2 from being hindered.

[0028] The pouring mechanism includes a metering pump 41 arranged at intervals at the bottom of the pouring material box 2, and a protruding pouring pipe 42 is installed at the output end of the metering pump 41;

[0029] The moving mechanism includes a track 51 symmetrically arranged outside the workbench, an electric slide 52 that can move back and forth is installed in the track 51, and a casting material box 2 is clamped between the two electric slides 52;

[0030] The scraper mechanism includes a cylinder 61 arranged at the back of the casting material box 2. A movable piston rod 62 is installed in the inner cavity of the cylinder 61. The other end of the piston rod 62 is connected to a suspension 63. The suspension 63 is connected to a scraper 65 through a connecting plate 64.

[0031] In this embodiment, the resin mixture prepared in the batching kettle 1 is transported to the casting box 2 through a transmission mechanism. A metering pump 41 is provided at the bottom of the casting box 2 to control the supply amount of the resin mixture, and the resin mixture is poured into the mold through a pouring pipe 42.

[0032] Through the operation of the moving mechanism, the pouring box 2 moves back and forth in the track 51 along with the electric slide 52, and the pouring of the mold is completed within one displacement cycle;

[0033] During the pouring process, the scraper mechanism works, the cylinder 61 drives the piston rod 62 to extend, and drives the scraper 55 connected to one side of the suspension 63 to contact the surface of the mold. During the displacement process, the excess resin mixture is scraped off the surface of the mold to maintain the uniform distribution of the resin mixture in the mold grooves, thereby solving the problem of uneven molding of the subsequent solidified FRP grating and difficulty in demolding the attached mold.

[0034] It should be supplemented that the scraper 65 and the suspension 63 move synchronously, and the end surface of the scraper 65 attached to the mold to be cast is an inclined structure.

[0035] The end surface attached to the mold to be cast is an inclined structure. The inclined scraper 65 can push and scrape excess resin mixture away from the surface of the mold, and the inclined slope can retain part of the resin mixture.

[0036] It is understandable that a suction mechanism may be added to the scraper 65 to suck the excess resin mixture out of the mold to reduce material waste.

[0037] As a working example of the stirring mechanism: the stirring mechanism includes a driving device 11 installed on the top of the batching kettle 1, and a stirring shaft 12 penetrating the inner cavity of the batching kettle 1 is installed at the output end of the driving device 11. The stirring shaft 12 is a rotating structure, and the outer wall is provided with a first stirring frame 13 and a second stirring frame 14. The driving device 11 drives the stirring shaft 12 to rotate, and drives the first stirring frame 13 and the second stirring frame 14 provided on the outer wall thereof to stir and mix the resin raw material and the catalyst in the inner cavity of the batching kettle 1 to form a resin mixture for casting.

[0038] The first stirring frame 13 includes six stirring paddles, which are the main stirring structure for mixing materials, and the second stirring frame 14 includes four stirring paddles, which are the auxiliary stirring structure for preventing the resin from solidifying.

[0039] In an optional embodiment, a spacing is left between the pouring tubes 42, and the spacing specification is the same as the spacing of the raised sections of the mold to be cast, so as to directly inject the resin mixture output by the pouring tubes 42 into the cavity of the mold to be cast.

[0040] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
