[0026] Embodiment

[0027] The embodiment provides an injection molding equipment of an air volume switch, the air volume switch comprises a common piece 1 and a gear piece 2, the injection molding equipment comprises a static mold body 3 and a movable mold body 4 opposite to the static mold body 3, the movable mold body 4 has a first position in a separated state with the static mold body 3 and a second position when the movable mold body 4 is attached to the static mold body 3, the static mold body 3 has an injection molding cavity 31 for placing the common piece 1 and the gear piece 2, the movable mold body 4 has a stamping column 5 for breaking ribs of the common piece 1 and the gear piece 2 to form a plurality of metal pieces, and the static mold body 3 is further provided with an injection molding port 6 for injecting material into the injection molding cavity 31.

[0028] The specific improvement is that Figure 1 and Figure 2As shown, before injection molding, the common piece 1 and the stop piece 2 are installed into the injection cavity 31 of the stationary mold body 3. Then, the moving mold body 4 moves to one side of the stationary mold body 3. The stamping column 5 on the moving mold body 4 will break the common piece 1 and the stop piece 2 into multiple metal pieces. The broken scrap parts of the common piece 1 and the stop piece 2 will be squeezed downwards. (The position of the stamping column 5 can be determined according to the product model to determine the location of the main broken ribs, and then customized.) After the moving mold body 4 and the stationary mold body 3 are in place, the injection tube in the injection port 6 begins to inject material into the injection cavity 31 to form a package around the common piece 1 and the stop piece. The housing of piece 2 encapsulates the waste material, eliminating the need for additional cleaning. This allows the common piece 1 and the stop piece 2 to be injection molded together with the housing. Compared to existing technologies, during the initial installation, it is only necessary to install the common piece 1 and the metal piece onto the mold, and then use the mold for stamping and forming. Compared to the existing technology, which involves first placing the metal piece and the stop piece 2 into one mold for stamping, and then placing the stamped metal piece into a second mold for injection molding, this significantly reduces the installation process, simplifies the production steps, and improves production efficiency.

[0029] Based on the above embodiments: the injection cavity 31 has a positioning plate 32, the positioning plate 32 includes a first receiving cavity 33 for inserting the stop piece 2 and a second receiving cavity 34 for inserting the common piece 1, and the injection cavity 31 is provided with a support column 7 for supporting the common piece 1.

[0030] The specific improvements mentioned above are as follows: Figure 5 As shown, the injection cavity 31 has a positioning plate 32, and the positioning plate 32 has a first receiving cavity 33 and a second receiving cavity 34. The unbroken common piece 1 and the stop piece 2 each have four pins. The four pins of the common piece 1 are inserted into the first receiving cavity 33, and the four pins of the stop piece 2 are inserted into the second receiving cavity 34. Through the setting of the first receiving cavity 33 and the second receiving cavity 34, the positions of the common piece 1 and the stop piece 2 can be effectively fixed, which facilitates subsequent injection molding.

[0031] Based on the above embodiments: the common piece 1 includes a grounding piece 11, a common connecting piece 12, and a first stop 21; the stop piece 2 includes a second stop 22, a third stop 23, and a fourth stop 24; the stamping column 5 includes a first pressing column 51, a second pressing column 52, a third pressing column 53, a fourth pressing column 54, and a fifth pressing column 55; the first pressing column 51 is located at the connection between the common connecting piece 12 and the first stop 21; the second pressing column 52 and the third pressing column 53 are located at the connection between the common connecting piece 12 and the grounding piece 11; the fourth pressing column 54 is located at the connection between the second stop 22 and the third stop 23; and the fifth pressing column 55 is located at the connection between the third stop 23 and the fourth stop 24. The moving mold body 4 is also provided with several support frames 8 for positioning the common piece 1 and the stop piece 2.

[0032] The specific improvement is that, as shown in Figures 2-5 The air volume switch has three contacts, the third contact is always in contact with the grounding sheet 11, the first contact is always in contact with the common sheet 1, and the second contact is in contact with any one of the first gear 21, the second gear 22, the third gear 23, or the fourth gear 24. The first pressing column 51 can break the connection between the common connecting sheet 12 and the first gear 21, the second pressing column 52 and the third pressing column 53 can break the connection between the common connecting sheet 12 and the grounding sheet 11, the fourth pressing column 54 can break the connection between the second gear 22 and the third gear 23, and the fifth pressing column 55 can break the connection between the third gear 23 and the fourth gear 24. Through the arrangement of the first pressing column 51, the second pressing column 52, the third pressing column 53, the fourth pressing column 54, and the fifth pressing column 55, the common sheet 1 and the gear sheet 2 can be broken into multiple separate metal sheets, which facilitates subsequent injection molding.

[0033] On the basis of the above embodiment, an elastic member 13 is arranged below the positioning plate 32, and when the movable mold body 4 is switched from the second position to the first position, the elastic member 13 can push the positioning plate 32 towards the side close to the movable mold body 4.

[0034] The specific improvement is that, as shown in Figure 1 When the injection molding is completed, the movable mold body 4 moves away from the stationary mold body 3, and then the cylinder below the positioning plate 32 pushes the positioning plate 32 upwards. The cylinder is sleeved with an elastic member 13 inside, and after the cylinder is pushed upwards, the injection-molded air volume switch is demolded. Due to the elastic restoring force of the elastic member 13, the positioning plate 32 is driven to reset, thereby completing a whole demolding process.

[0035] On the basis of the above embodiment, a counter-inserting structure 9 is arranged between the stationary mold body 3 and the movable mold body 4. The counter-inserting structure 9 includes a correcting column 91 arranged on one side of the movable mold body 4 and a correcting groove 92 arranged on one side of the stationary mold body 3 for the insertion of the correcting column 91.

[0036] The specific improvement is that, as shown in Figure 6 Through the arrangement of the correcting column 91 and the correcting groove 92, the position of the movable mold body 4 and the stationary mold body 3 can be corrected when they are attached, thereby ensuring that the movable mold body 4 and the stationary mold body 3 can be attached.

[0037] On the basis of the above embodiment, a supporting rod 93 is arranged on the positioning plate 32 and inserted into the first gear 21.

[0038] The specific improvement is that, as shown in Figure 2 and Figure 3As shown, through the arrangement of the support rod 93, the first gear 21 can be effectively supported, and is prevented from being pressed and deformed during installation, thereby increasing the product scrap rate.

[0039] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation on the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
