Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning filter mold technology, and in particular to a mold for automotive air conditioning filters. Background Technology
[0002] A mold is a tool or device used in industrial production to shape materials into products with specific shapes and sizes through pressure or external force. It is one of the core process equipment in manufacturing, enabling mass production, ensuring product quality, and reducing production costs. It is widely used in almost all industrial sectors, including automobiles, electronics, home appliances, medical devices, and aerospace.
[0003] In existing technologies, when manufacturing air conditioning filters, molds are used to shape the filters. This process can precisely control the filter's dimensions and structural details, ensuring that the produced filter is perfectly matched to the installation position of the car's air conditioning system and avoiding installation difficulties caused by dimensional deviations.
[0004] However, in the mold production process, the upper and lower molds are combined to shape the object. If the tightness between the two is insufficient, leakage may occur, causing the injection material to overflow from the gap, resulting in material waste. It will also cause uneven internal structure density of the produced object, and voids or weak points in key stress parts due to insufficient filling, resulting in insufficient overall strength. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mold for automotive air conditioning filter elements.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mold for an automotive air conditioning filter element, comprising a tensioning mechanism, a limiting mechanism provided on the outer side of the tensioning mechanism, the tensioning mechanism including a locking cavity, a semi-circular rod provided on the inner surface of the locking cavity, the inner surface of the locking cavity being rotatably engaged with the outer top end of the semi-circular rod, a driving handle provided at the bottom end of the semi-circular rod, the bottom end of the semi-circular rod being fixedly connected to the top end of a driving plate, a connecting rod provided at the bottom end of the driving handle, the bottom end of the driving handle being rotatably connected to the top end of the connecting rod, a sleeve provided on the outer side of the connecting rod, the outer side of the connecting rod being slidably connected through the inner wall of the sleeve, a crossbar provided on one side of the sleeve, and one side of the sleeve being fixedly connected to one end of the crossbar.
[0007] In a preferred embodiment, the limiting mechanism includes a ratchet, a pawl is provided on the outer side of the ratchet, the outer side of the ratchet is rotatably engaged with the top end of the pawl, a base is provided at the bottom end of the pawl, and the bottom end of the pawl is rotatably connected to one side end of the base.
[0008] In a preferred embodiment, a spring is provided on one side of the pawl, and one side of the pawl is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to the top side of the base. A rotating rod is provided on the inner wall of the ratchet, and the inner wall of the ratchet is fixedly connected to the rotating rod through it.
[0009] In a preferred embodiment, a protruding rod is provided on the top side of the middle end of the crossbar, and the top side of the middle end of the crossbar is rotatably in contact with one end of the protruding rod. The inner wall of the protruding rod is fixedly connected to the outer side of the rotating rod.
[0010] In a preferred embodiment, the outer side of the rotating rod is rotatably connected to the inner wall of the base, and a knob is provided at one end of the rotating rod, with the center of the knob being fixedly connected to the one end of the rotating rod.
[0011] In a preferred embodiment, a lower mold is provided at the top of the base, the top of the base is fixedly connected to the bottom side of the lower mold, a positioning ring is provided at one end of the lower mold, one end of the lower mold is fixedly connected to one side end of the positioning ring, and the inner surface of the positioning ring is rotatably connected to the outer side of the drive handle.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. By aligning the semi-circular rod with the inlet of the lock cavity, the upper and lower molds are then fitted together. Simultaneously, the semi-circular rod is positioned inside the lock cavity. By rotating the drive handle 180 degrees, the protrusion of the semi-circular rod is made to fit against the inner wall of the lock cavity. By inserting a rod-shaped object into the knob and rotating the knob, the rotating rod and the protruding rod rotate synchronously, applying downward pressure to the horizontal plate. This causes the semi-circular rod to lift the lock cavity, further tightening the lower and upper molds to prevent leakage and ensure the integrity of the formed object.
[0016] 2. By installing a ratchet on the rotating rod, the pawl will always be engaged with the ratchet under the tension of the spring when rotating. At the same time, after the rotating rod has finished rotating, the pawl will immediately engage with the ratchet to prevent the rotating rod from rotating in the opposite direction. This will firmly maintain the downward pressure of the crossbar on the connecting rod and ensure that the semi-circular rod does not loosen its support to the locking cavity.

[0028] Example 1
[0029] like Figure 1 - Figure 7As shown, this utility model provides a technical solution: a mold for an automotive air conditioning filter element, including a tensioning mechanism 1, a limiting mechanism 2 provided on the outer side of the tensioning mechanism 1, the tensioning mechanism 1 including a locking cavity 13, a semi-circular rod 14 provided on the inner surface of the locking cavity 13, the inner surface of the locking cavity 13 being rotatably engaged with the outer side of the top end of the semi-circular rod 14, a driving handle 112 provided at the bottom end of the semi-circular rod 14, the bottom end of the semi-circular rod 14 being fixedly connected to the top end of a driving plate, a connecting rod 16 provided at the bottom end of the driving handle 112, the bottom end of the driving handle 112 being rotatably connected to the top end of the connecting rod 16, a sleeve 17 provided on the outer side of the connecting rod 16, the outer side of the connecting rod 16 being slidably connected through the inner wall of the sleeve 17, a crossbar 18 provided on one side of the sleeve 17, one side of the sleeve 17 being fixedly connected to one end of the crossbar 18, and a protruding rod 1 on the top side of the middle end of the crossbar 18. 10. The top side of the middle end of the crossbar 18 is rotatably connected to one end of the protruding rod 110. The inner wall of the protruding rod 110 is fixedly connected to the outer side of the rotating rod 19. The outer side of the rotating rod 19 is rotatably connected to the inner wall of the base 113. A knob 111 is provided at one end of the rotating rod 19. The center of the knob 111 is fixedly connected to one end of the rotating rod 19. A lower mold 11 is provided at the top of the base 113. The bottom side of the base 113 is fixedly connected to the bottom side of the lower mold 11. A positioning ring 15 is provided at one end of the lower mold 11. The side side of the lower mold 15 is fixedly connected to one end of the positioning ring 15. The inner surface of the positioning ring 15 is rotatably connected to the outer side of the drive handle 112. An upper mold 12 is provided at the top side of the lower mold 11. The top side of the lower mold 11 and the bottom side of the upper mold 12 are fitted and correspond to each other. The inner wall of the upper mold 12 is fixedly connected to the outer side of the locking cavity 13.
[0030] In this embodiment, when this type of automotive air conditioning filter mold is used, firstly, a lower mold 11 is fixed at the top of the base 113, and an upper mold 12 is correspondingly located on the top side of the lower mold 11. A locking cavity 13 is designed on the inner wall of the upper mold 12. The inner wall of the locking cavity 13 is annular in diameter. At the same time, a positioning ring 15 is installed at one end of the lower mold 11. A drive handle 112 is designed on the inner surface of the positioning ring 15. The drive handle 112 can move up and down and rotate within the positioning ring 15. A semi-circular rod 14 is fixed at the top of the drive handle 112. By aligning the semi-circular rod 14 with the inlet of the locking cavity 13, the upper mold 12 and the lower mold 11 are fitted together. At the same time, the semi-circular rod 14 will be located inside the locking cavity 13. Then, by rotating the drive handle 112 180 degrees, the protrusion of the semi-circular rod 14 is fitted with the inner wall of the locking cavity 13, and a structural connection is formed between the lower mold 11 and the upper mold 12.
[0031] A connecting rod 16 is designed at the bottom of the drive handle 112. The connecting rod 16 is rotatably connected to the drive handle 112. A sleeve 17 is designed on the outside of the connecting rod 16. Under the action of the sleeve 17, the connecting rod 16 can only move vertically. At the same time, a crossbar 18 is fixedly connected to one side of the sleeve 17. A protruding rod 110 is designed at the middle end of the crossbar 18. A rotating rod 19 is fixedly fixed through the inner wall of the protruding rod 110. A knob 111 is installed at one end of the rotating rod 19. Therefore, by inserting a rod-shaped object into the knob 111 and rotating the knob 111, the rotating rod 19 and the protruding rod 110 rotate synchronously and exert downward pressure on the crossbar. In turn, the semi-circular rod 14 pushes the locking cavity 13 down, so that the lower mold 11 and the upper mold 12 fit more tightly, avoiding leakage and ensuring the integrity of the object after molding.
[0032] Example 2
[0033] like Figure 5 - Figure 7 As shown, the limiting mechanism 2 includes a ratchet 21, a pawl 22 is provided on the outer side of the ratchet 21, the outer side of the ratchet 21 is rotatably engaged with the top of the pawl 22, a base 113 is provided at the bottom end of the pawl 22, the bottom end of the pawl 22 is rotatably connected to one side of the base 113, a spring 23 is provided on one side of the pawl 22, one side of the pawl 22 is fixedly connected to one end of the spring 23, the other end of the spring 23 is fixedly connected to the top side of the base 113, and a rotating rod 19 is provided on the inner wall of the ratchet 21, the inner wall of the ratchet 21 is fixedly connected to the rotating rod 19 through it.
[0034] In this embodiment, a ratchet 21 is installed on the outside of the rotating rod 19, and a pawl 22 is designed on one side of the ratchet 21. A spring 23 is fixed on one side of the pawl 22, and the other end of the spring 23 is fixed on the base 113. Thus, during the rotation of the rotating rod 19, the pawl 22 will be continuously engaged with the ratchet 21 under the tension of the spring 23. After the rotating rod 19 has finished rotating, the pawl 22 will immediately engage with the ratchet 21, preventing the rotating rod 19 from rotating in the opposite direction. This stabilizes the downward pressure of the crossbar 18 on the connecting rod 16, ensuring that the semi-circular rod 14 does not loosen its support on the locking cavity 13, and maintaining the tight fit between the lower mold 11 and the upper mold 12 for a long time.
[0035] Working principle:
[0036] like Figure 1 - Figure 7As shown, by aligning the semi-circular rod 14 with the inlet of the lock cavity 13, the upper mold 12 and the lower mold 11 are fitted together accordingly, while the semi-circular rod 14 is located inside the lock cavity 13. Then, by rotating the drive handle 112 180 degrees, the protrusion of the semi-circular rod 14 is fitted with the inner wall of the lock cavity 13, and a structural connection is formed between the lower mold 11 and the upper mold 12. Finally, by inserting a rod-shaped object into the knob 111, the knob 111 is rotated, causing the rotating rod 19 and the protruding rod 110 to rotate synchronously and exert downward pressure on the horizontal plate. This causes the semi-circular rod 14 to lift the lock cavity 13, making the lower mold 11 and the upper mold 12 fit together more tightly and preventing leakage.
[0037] During the rotation of the lever 19, the pawl 22 will be engaged with the ratchet 21 under the tension of the spring 23. At the same time, after the lever 19 finishes rotating, the pawl 22 will immediately engage with the ratchet 21 to prevent the lever 19 from rotating in the opposite direction. This will stabilize the downward pressure of the crossbar 18 on the connecting rod 16 and ensure that the semi-circular rod 14 does not loosen its support to the locking cavity 13.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
