Description

Technical Field

[0001] The utility model relates to the technical field of pultruded profiles, in particular to a glue injection box. Background Art

[0002] The composite material pultrusion process is a process for producing composite material profiles by impregnating continuous fibers or their fabrics with resin under the traction of a traction device and curing the resin by heating a molding die.

[0003] Among them, the composite material pultrusion system must use a special glue injection box, and the mold core is inserted into the glue injection box to form a cavity inside the pultruded profile.

In addition, the existing glue injection box cannot adapt to the processing of pultruded profiles of different specifications and sizes, thereby reducing production efficiency. Utility Model Content

Through the above-mentioned arrangement, the glue injection box of this embodiment can be easily disassembled and maintained, thereby ensuring the stability of the mold core 100 during the glue injection process, improving product quality, and having a wider adaptability.

[0034] It should be noted that the detachable connections between the above components can be achieved by screw connection, clamping connection, etc., and no further limitations are given here.

[0035] Specifically, Figure 1 As shown, the glue injection box also includes a glue injection tube 6, one end of which is connected to the glue injection channel 10, and the other end is used to connect to the output end of the glue injection machine, ensuring that the glue can flow smoothly from the glue injection machine into the glue injection channel 10, ensuring that the glue is fully in contact with the fiber layer in the glue injection box, and improving product quality. Among them, the glue injection machine is a conventional device in this field, and thus will not be described in detail.

[0036] More specifically, if Figure 1 As shown, the glue injection tube 6 is arranged on the top plate 4, so that the structure of the entire glue injection box is more compact and stable, which is convenient for cleaning and maintenance of the glue injection box and prolongs the service life of the glue injection box.

[0037] Specifically, Figure 1 and Figure 2As shown, the glue injection box also includes a first connecting member 7. Along the extension direction of the glue injection channel 10, the first connecting member 7 is arranged on the opposite ends of the bottom plate 1 for connecting the glue injection mold. Through the first connecting member 7, the glue injection box can be stably and firmly connected to the glue injection mold to ensure that no relative movement or misalignment occurs during the glue injection process, thereby ensuring product quality. Among them, the first connecting member 7 can be implemented by a pin or a bolt, which is not limited here. In addition, the glue injection mold is a conventional device in this field, so the technical principle is clear to the technicians in this field and will not be repeated here.

[0038] Specifically, Figure 1 and Figure 2 As shown, the glue injection box also includes a second connecting member 8, which is arranged on the opposite ends of the top plate 4 along the extension direction of the glue injection channel 10, and is used to connect the glue injection mold. Through the second connecting member 8, the glue injection box can be stably and firmly connected to the glue injection mold, ensuring that no relative movement or dislocation occurs during the glue injection process, thereby ensuring product quality. Among them, the second connecting member 8 can be implemented by a pin or a bolt, and no excessive restrictions are made here.

[0039] Specifically, Figure 1-Figure 3 As shown, the yarn partition plate 5 includes a lower partition plate 51 and an upper partition plate 52, one end of the lower partition plate 51 is connected to the bottom plate 1, one end of the upper partition plate 52 is connected to the top plate 4, and the mold core 100 is clamped between the other end of the lower partition plate 51 and the other end of the upper partition plate 52 to ensure that the mold core 100 will not move or misalign during the injection process, thereby improving the molding quality of the product.

[0040] Specifically, Figure 1-Figure 3 As shown, the yarn partition plate 5 also includes a left partition plate 53 and a right partition plate 54, one end of the left partition plate 53 is connected to the first side plate 2, one end of the right partition plate 54 is connected to the second side plate 3, and the mold core 100 is sandwiched between the other end of the left partition plate 53 and the other end of the right partition plate 54, further ensuring that the mold core 100 will not move or misalign during the glue injection process, thereby improving the molding quality of the product. Through the joint action of the lower partition plate 51, the upper partition plate 52, the left partition plate 53 and the right partition plate 54, the mold core 100 can maintain a stable position during the glue injection process, thereby ensuring the uniformity and accuracy of the glue injection effect.

[0041] More specifically, there are a plurality of left baffles 53, which are arranged at intervals in the vertical direction, thereby forming a plurality of partitions on the left side of the mold core 100, which helps to separate the fiber layer, control the flow direction and speed of the colloid, and ensure the stability of the mold core 100 during the injection process. There are a plurality of right baffles 54, which are arranged at intervals in the vertical direction, and the right baffles 54 cooperate with the left baffles 53 to form a plurality of partitions on the right side of the mold core 100, further ensuring the uniform flow of the colloid and the stability of the mold core 100.

[0042] Specifically, Figure 1-Figure 3 As shown, the first side plate 2 and the second side plate 3 are both provided with connecting recesses, which are arranged on the upper and lower ends of the first side plate 2 and the second side plate 3, and the bottom plate 1 and the top plate 4 are both provided with connecting protrusions that cooperate with the connecting recesses, and the connecting protrusions are arranged on the end surfaces of the bottom plate 1 and the top plate 4 facing each other. By interlocking the connecting protrusions and the connecting recesses, and connecting the bottom plate 1, the first side plate 2, the second side plate 3 and the top plate 4 to each other through bolts, the structural stable connection and sealing of the glue injection box are realized, and the leakage and waste of the glue during the glue injection process are effectively prevented.

[0043] Specifically, Figure 1-Figure 3 As shown, multiple yarn partition plates 5 all extend toward the injection channel 10, and the mold core 100 abuts against multiple yarn partition plates 5, so that the injection channel 10 can be divided into multiple yarn threading channels 20. The yarn threading channels 20 can accommodate the fiber layer inserted in the injection box and divide the fiber layer into multiple strands, providing the necessary space for the pultrusion molding of the composite material. Through the above arrangement, not only can the mold core 100 be fixed and limited to ensure the quality of product molding, but also the fiber layer can be effectively divided into strands, ensuring the uniform distribution of the colloid during the injection process, further ensuring the product quality.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
