Detailed Description
The injection molding breather pipe of the automobile engine is of an integrated structure and is injection molded by plastic materials; the manufacturing cost and the weight of the injection molding part can be greatly reduced compared with the casting part; therefore, when the breather pipe is manufactured in an injection molding mode, the problems of heavy weight and high manufacturing cost existing in the existing casting water pipe can be solved.
The injection-molded vent pipe is composed of a connecting disc 1, a vent elbow 2, a communicating cylinder 3 and a transverse connecting pipe 6 (see the attached figure 1 in the specification).
The center of the connecting disc 1 is provided with a vent elbow 2 (see the attached figure 1 in the specification); the vent elbow 2 is a right-angle elbow (see the attached figure 1 in the specification).
A reinforcing rib plate A8 (see the attached figure 1 in the specification) is arranged between the transverse part and the vertical part of the vent elbow 2 and the connecting disc 1; the purpose of arranging the reinforcing rib plate A8 is as follows: the transverse part and the vertical part of the ventilating elbow 2 are connected with the connecting disc 1 into a whole through the reinforcing rib plate A8, so that the aim of enhancing the structural strength of the ventilating elbow 2 is fulfilled.
The lower end of the vent elbow 2 is communicated with the lower surface of the connecting disc 1; the lower surface of the connecting disc 1 around the lower end of the vent elbow 2 is provided with a sealing cylinder 13 (see the attached figure 4 in the specification); the circumferential surface of the seal cylinder 13 is provided with a seal ring groove B14. The injection molding breather pipe can be communicated with an automobile engine through a sealing cylinder 13; during assembly, the sealing ring is arranged in the sealing ring groove B14, so that the aim of enhancing the sealing performance of the sealing cylinder 13 can be achieved, and the leakage problem is avoided.
The two sides of the connecting disc 1 are symmetrically provided with connecting lugs 4, and connecting holes 5 are formed in the connecting lugs 4; the injection molding breather pipe can be arranged on an automobile engine through a connecting hole 5 connected with the support lug 4. The side of the connecting disc 1 is provided with a mounting lug 7 (see the attached figure 2 in the specification).
The connecting support lug 4 and the assembling support lug 7 are both in a disc-shaped structure; the connecting support lug 4 and the connecting disc 1 and the assembling support lug 7 and the connecting disc 1 are in arc transition connection (see the attached figure 2 in the specification). The purpose of so setting up and linking the journal stirrup 4 and assembling the journal stirrup 7 is: the problem that the connection lug 4 and the assembly lug 7 are easy to crack due to stress concentration when the connection lug 4 and the assembly lug 7 are connected with the connecting disc 1 in other modes is solved.
