Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example Please refer to Figure 1-9 The present invention provides the following technical solution: an injection mold for a car door handle base, comprising a mold body 1, an exhaust pipe hole 2 provided on the mold body 1, a connecting shield 3 that can be inserted into the exhaust pipe hole 2, a connecting member 4 installed on the shield 3, and a limiting member 5 installed on the connecting member 4.

[0017] The shielding part 3 is inserted into both ends of the vent pipe hole 2 to seal both ends of the vent pipe hole 2, preventing impurities and waste from entering the vent pipe hole 2 during cleaning of the mold body 1. The connecting part 4 is connected to the shielding part 3 to facilitate the use of the rope 6 and the limiting part 5. The rope 6 is used to limit the shielding part 3 located on the outside of the mold body 1, while the limiting part 5 is used to limit the shielding part 3 located on the inside of the mold body 1, so as to achieve stable placement of the shielding part 3.

[0018] Please refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The shielding component 3 includes a sealing plug 301, a round block 302, and a through hole 303. One end of the sealing plug 301 is connected to the round block 302. The side wall of the round block 302 has two symmetrically distributed through holes 303. The sealing plug 301 is frustum-shaped. Both the sealing plug 301 and the round block 302 are made of rubber. The connecting component 4 includes a connecting block 401, a first screw hole 402, a second screw hole 403, a placement groove 404, and a slot 405. One end of the connecting block 401 has two symmetrically distributed placement grooves 404, and one end of the connecting block 401 also has a second screw hole 403. A screw hole 402 is provided, and a slot 405 is provided on the side wall of the other end of the connecting block 401. Two symmetrically distributed second screw holes 403 are provided on the top of the connecting block 401. The second screw holes 403 are connected to the slot 405. The first screw hole 402 is located between two placement slots 404. The round block 302 can be inserted into the slot 405. The through hole 303 can be aligned with the second screw hole 403. A first screw 7 can be threadedly connected to the side wall of the second screw hole 403. A second screw 8 can be threadedly connected to the first screw hole 402. A rope 6 can be wrapped and pressed in the placement slot 404.

[0019] The sealing plug 301 is inserted into the exhaust pipe hole 2. The sealing plug 301 is frustoconical in shape and made of rubber, so that the sealing plug 301 can fit exhaust pipe holes 2 with diameters within a certain range, thereby improving the application range of the sealing plug 301. Insert the round block 302 into the slot 405 and align the through hole 303 with the second screw hole 403. Screw the first screw 7 into the second screw hole 403 and through the through hole 303 to fix the round block 302 and the connecting block 401 together. At this time, the rope 6 is placed into the placement groove 404 located on the outside of the mold body 1, and the rope 6 is wrapped around the mold body 1. The connecting block 401 is fixed to the mold body 1 by the rope 6, thereby achieving the limiting and stabilizing of the sealing plug 301.

[0020] Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 8 and Figure 9 The limiting component 5 includes a support block 501, a third screw hole 502, a through hole 503, and a screw 504. The front side wall of the support block 501 has a through hole 503. The size of the support block 501 is smaller than the size of the connecting block 401. The side wall of the support block 501 has two vertically distributed third screw holes 502. The screw 504 is internally threaded into the third screw hole 502. The two screws 504 are screwed into the third screw hole 502 in opposite directions. The through hole 503 can be aligned with the first screw hole 402. One end of the screw 504 is connected to a rubber pad 9.

[0021] Since the connecting block 401 located inside the mold body 1 is not convenient to use with the rope 6, the screws 504 are screwed into different third screw holes 502 in opposite directions. Then, the connecting block 401 located inside the mold body 1 is placed against the support block 501 (the third screw hole 502 mentioned above where the screws 504 are screwed into, which is located on the support block 501), and the through hole 503 is aligned with the first screw hole 402. The second screw 8 is then screwed into the first screw hole 402 (see reference). Figure 5 The second screw 8 passes through the through hole 503, thereby fixing the support block 501 and the connecting block 401 together. At this time, the adjusting screw 504 can be pressed against the inner wall of the mold body 1, thereby limiting the support block 501 and achieving stable limiting of the sealing plug 301 located inside the mold body 1. The rubber pad 9 on the screw 504 can prevent the screw 504 from compressing the mold body 1.

[0022] The working principle and usage process of this utility model: In specific use, the sealing plug 301 is inserted into the exhaust pipe hole 2. By utilizing the frustum shape of the sealing plug 301 and the fact that the sealing plug 301 is made of rubber, the sealing plug 301 can be adapted to exhaust pipe holes 2 with diameters within a certain range, thereby improving the application range of the sealing plug 301. Insert the round block 302 into the slot 405 and align the through hole 303 with the second screw hole 403. Screw the first screw 7 into the second screw hole 403 and through the through hole 303 to fix the round block 302 and the connecting block 401 together. At this time, the rope 6 is placed into the placement groove 404 located on the outside of the mold body 1, and the rope 6 is wrapped around the mold body 1. The connecting block 401 is fixed to the mold body 1 by the rope 6, thereby achieving the limiting and stabilizing of the sealing plug 301.

[0023] Since the connecting block 401 located inside the mold body 1 is not convenient to use with the rope 6, the screw 504 is screwed into different third screw holes 502 in opposite directions. Then, the connecting block 401 located inside the mold body 1 is attached to the support block 501, and the through hole 503 is aligned with the first screw hole 402. The second screw 8 is screwed into the first screw hole 402, and the second screw 8 passes through the through hole 503, so that the support block 501 and the connecting block 401 are fixedly connected as one. At this time, the screw 504 is adjusted so that the screw 504 can be pressed against the inner wall of the mold body 1, thereby limiting the support block 501 and realizing the stable limiting of the sealing plug 301 located inside the mold body 1. The rubber pad 9 on the screw 504 can prevent the screw 504 from compressing the mold body 1.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
