[0002] Carbon fiber materials possess high rigidity, low weight, superior tensile strength and tensile modulus, as well as high corrosion resistance, high X-ray penetration, and high resistance to chemicals, heat, and low temperatures. Therefore, replacing existing metal products with carbon fiber products has broad market prospects.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown, a quick-release nozzle for a carbon fiber blowing mold 20 is located between the carbon fiber blowing mold 20 and the blowing pipe of the blowing mechanism. It includes a rod part 11 for connecting to the carbon fiber blowing mold 20 and a nozzle part 12 for detachably connecting to the blowing pipe of the blowing mechanism.

[0029] In this embodiment, the rod body 11 and the carbon fiber blowing mold 20 are separately arranged. Of course, the rod body 11 and the carbon fiber blowing mold 20 are designed as an integral structure, which is not limited here.

[0030] One end of the rod portion 11 is used to connect to the carbon fiber blowing mold 20, and the other end of the rod portion 11 is integrally connected to the nozzle portion 12. The rod portion 11 has a first inner cavity 101 that communicates with the interior of the carbon fiber blowing mold 20.

[0031] In this embodiment, the first inner cavity 101 is a hollow cavity extending axially from the inner center of the rod portion 11. The axes of the first inner cavity 101 and the second inner cavity 102 described below coincide.

[0032] The rod body 11 includes a third step 111, a fourth step 112, and a fifth step 113 arranged sequentially from left to right. The outer diameter of the third step 111 is smaller than the outer diameter of the fourth step 112, and the outer diameter of the fifth step 113 is smaller than the outer diameter of the third step 111. The fifth step 113 is integrally connected to the left end of the second step 123.

[0033] The fifth step portion 113 has an annular protrusion 114 on its outer periphery. Several annular protrusions 114 are provided and arranged at intervals from right to left. The annular protrusions 114 are connected to the second step portion 123 described below through a second arc surface 115.

[0034] The nozzle portion 12 has a second inner cavity 102 that connects to the air blowing tube of the air blowing mechanism, and the first inner cavity 101 connects to the second inner cavity 102. In this embodiment, the second inner cavity 102 is a hollow cavity extending axially from the inner center of the nozzle portion 12.

[0035] In this embodiment, the nozzle portion 12 includes a first stepped portion 121, a first chamfered portion 122, and a second stepped portion 123 arranged sequentially from right to left. The outer diameter of the first stepped portion 121 is smaller than the outer diameter of the second stepped portion 123. The right end of the rod portion 11 is integrally connected to the left end of the second stepped portion 123. Preferably, the first inner cavity 101 extends to the right and penetrates into the second stepped portion 123. An annular groove 124 is recessed inward on the outer periphery of the second stepped portion 123.

[0036] In this embodiment, the rod portion 11 and the second step portion 123 are connected by a first arc surface 125.

[0037] The following is a brief explanation of the work process:

[0038] First, insert part of the rod 11 into the hole of the carbon fiber blowing mold 20, then install and connect the nozzle 12 to the blowing pipe of the blowing mechanism, and then start the blowing mechanism to blow air into the carbon fiber blowing mold 20 through the blowing pipe.

[0039] The key design feature of this utility model is that it connects the carbon fiber blowing mold and the blowing pipe of the blowing mechanism to the rod body and the nozzle part respectively, thereby realizing subsequent blowing molding, which greatly improves the installation efficiency and thus the molding efficiency.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
