Many special vehicles such as new energy vehicles and motorhomes often use micro water pumps as water circulation, cooling, or on-vehicle water supply systems. Such micro self-priming water pumps are collectively referred to as automotive water pumps. During the production and processing of electronic water pumps, very high requirements are placed on their overall sealing performance and airtightness performance. To meet the production requirements, airtightness detection operations are usually carried out on the electronic water pumps to be shipped out using an airtightness detector.

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] Embodiment 1

[0035] like Figure 1-7 As shown, the utility model provides a quick-release tool for detecting air tightness of an electronic water pump, the quick-release tool comprising: a lower base 1, a lower mold 2, an upper base 3 and an upper mold 4;

[0036] An upper base 3 capable of resting against the lower mold 2 is horizontally and liftably arranged above the lower base 1. The facing surfaces of the lower base 1 and the upper base 3 are respectively detachably provided with a lower mold 2 and an upper mold 4 for use with them through a quick release mechanism 5. The quick release mechanism 5 is composed of a No. 1 base 510, a No. 1 limit block 511 and a No. 1 fastener 512; wherein,

[0037] The facing surfaces of the lower base 1 and the upper base 3 are respectively spaced apart and horizontally fixed with two No. 1 bases 510 for assembling the lower mold 2 and the upper mold 4, and the two sides of the lower mold 2 and the upper mold 4 are respectively fitted with the two No. 1 bases 510, and the upper end of each of the No. 1 bases 510 is spaced apart and horizontally movably provided with a plurality of No. 1 limit blocks 511 that can move toward the lower mold 2 or the upper mold 4 and the bottom can rest thereon, and each of the No. 1 bases 510 is provided with a No. 1 fastener 512 that can lock the No. 1 limit block 511 after movement.

[0038] In the above solution, the ends of the two facing surfaces of the No. 1 base 510 are partially protruded to form limit blocks adapted to the lower mold 2 .

[0039] like Figure 4-6As shown, the at least one lower base 1 is horizontally fixed inside the cabinet body, and the upper base 3 is assembled above the lower base 1 in a liftable manner. Among them, a fixing plate 6 is horizontally and fixedly arranged inside the cabinet body directly above the lower base 1. A servo electric cylinder 7 is vertically and fixedly arranged through the fixing plate 6, and the upper base 3 is horizontally fixed on the telescopic end of the servo electric cylinder 7. The servo electric cylinder 7 is used to drive the upper base 3 to drive the upper mold 4 fixed thereon to descend until the upper mold 4 abuts against the lower mold 2. The mold cavity formed inside the upper mold 4 and the lower mold 2 is used to fix the electronic water pump to be detected.

[0040] In addition, an air outlet hole 18 is vertically penetrated and arranged on the lower base 1 inside the lower mold 2, and a first sealing ring is fixedly arranged on the lower base 1. The bottom end of the lower mold base 2 can abut against the first sealing ring to make the space between the lower mold 2 and the lower base 2 airtight. A second sealing ring is horizontally and fixedly arranged at the upper end of the lower mold 2, and the upper mold 4 can abut against the second sealing ring so that when the upper mold 4 descends onto the lower mold 2, the upper mold 4 can squeeze the second sealing ring to ensure that the mold cavity formed between the upper mold 4 and the lower mold 2 is in an airtight state, which is convenient for accurately and reliably detecting the airtightness of the electronic water pump fixed in the mold cavity formed by the lower mold 2 and the upper mold 4 in the later stage. A gas inlet pipe communicating with its interior is horizontally and fixedly arranged on the side wall of the lower mold 2, and the gas inlet pipe is connected to the external detection gas source. During detection, the air outlet end of the airtight detector is connected to the gas inlet pipe, and the air inlet end of the airtight detector is connected to the external gas source, so as to inject the external gas source into the lower mold 2 through the gas inlet pipe by the airtight detector and enter the mold cavity formed by splicing the upper mold 4 and the lower mold 2 through the air outlet hole 18 of the lower mold 2.

[0041] During detection, the electronic water pump to be detected is vertically placed in the cavity of the lower mold 2, and the upper mold 4 is driven to abut against the lower mold 2 so that the electronic water pump is sealed in the mold cavity formed by splicing the inner cavity of the lower mold 2 and the inner cavity of the upper mold 4, and the electronic water pump fits against the inner wall of the mold cavity formed by splicing the inner cavity of the lower mold 2 and the inner cavity of the upper mold 4.

[0042] Enclose the electronic water pump to be detected in a sealed mold cavity. When the upper mold 4 descends and abuts against the lower mold 2, the bottom end of the upper mold 4 presses the second sealing ring on the lower mold 2, so that the connection between the upper mold 4 and the lower mold 2 is in a sealed state, improving the sealing performance of the sealed mold cavity formed by the upper mold 4 and the lower mold 2. Connect the airtightness detector to the factory air source (or booster pump). This step ensures the stable supply of the air source and is a prerequisite for gas injection. Then, accurately and effectively inject gas into the lower base 1 through the airtightness detector via the injection pipe, and finally enter the sealed mold cavity formed by the internal splicing of the upper mold 4 and the lower mold 2 through the air outlet hole 18 on the lower base 1. In addition, the first sealing ring on the bottom end of the lower mold 2 is to ensure the sealing performance between the lower mold 3 and the lower base 2, preventing gaps between the lower mold 2 and the lower base 1 from affecting the sealing performance inside the sealed mold cavity. And use the airtightness detector to detect the rate at which gas leaks from the product under test. According to the magnitude of the leakage rate, it can be judged whether the airtight performance of the product under test is qualified. And the airtightness detector used is prior art, so its specific structure and working principle will not be elaborated here again.

[0043] As Figure 1-7 shown, horizontally place the lower mold 2 between the two first bases 510, and the four sides of the lower mold 2 are respectively in contact with the two first bases 510 and the limit blocks on the first bases 510. Through the combined use of the two first bases 510 and the limit blocks at both ends of each first base 510, in the horizontal direction, the lower mold 2 can be limited, and move all the first limit blocks 511 on the two first bases 510 so that all the first limit blocks 511 on the two first bases 510 abut against both sides of the lower mold 2, and lock the first limit blocks 511 with the first fasteners 512, so that in the vertical direction, the lower mold 2 can be limited. Similarly, the upper mold 4 can be quickly assembled on the upper base 3 through the quick-release mechanism 5 in the same assembly manner.

[0044] During the assembly process, only need to place the lower mold 2 between the two first bases 510 and move the first limit blocks on the first bases 510 to lock the lower mold 2, so that the assembly of the lower mold 2 or the upper mold 4 can be quickly completed. Therefore, different-sized upper molds 4 and lower molds 3 can be quickly replaced through the quick-release mechanism 5 to be applicable to the airtightness detection of electronic water pumps of different sizes, improving the assembly effect.

[0045] In a preferred embodiment of the present utility model, on both sides of the lower mold 2 and the upper mold 4, there are respectively partially downward depressions to form a first limiting step 11 adapted to the first limiting block 511, and each first limiting block 511 moves towards the lower mold 2 or the upper mold 4 and can abut against the first limiting step 11 after moving. On each first base 510, there are several first limiting grooves 8 spaced apart and partially inwardly recessed for assembling all the first limiting blocks 511 thereon. And in each first limiting groove 8, there is a first fixing hole 9 vertically opened and adapted to the first fastener 512. On each first limiting block 511, there is a first strip-shaped hole adapted to the first fastener 512. The first fastener 512 can pass through the first strip-shaped hole and be screwed into the first fixing hole 9 on the first base 510 until the nut of the first fastener 512 abuts against the first limiting block 511 to lock the moved first limiting block 511.

[0046] In the above solution, the first fastener 512 is a bolt with threads provided at the bottom part.

[0047] During use, as Figure 1 、 2 、3, 5 and Figure 7 shown, place the lower mold 2 horizontally between the two first bases 510. The four sides of the lower mold 2 are respectively in contact with the two first bases 510 and the limiting blocks on the first bases 510 to limit the lower mold 2. Since the first fastener 511 and the first fixing hole 9 in the limiting groove 8 are in threaded connection, therefore, the first fastener 512 can be rotated to make the first fastener 511 rise in the first fixing hole 8 during rotation until the nut of the first fastener 512 at its top is away from the first limiting block 511, so that the nut of the first fastener 512 is separated from the first limiting block 511. Then move the first limiting block 511 to make the first limiting block 511 move towards the lower mold 2 until the first limiting block 511 abuts against the lower mold 2, and then rotate the first fastener 511 in the reverse direction until the nut of the first fastener 512 abuts against the first limiting block 511, thus completing the locking of the moved first limiting block 511.

[0048] In addition, since there is a first strip-shaped hole adapted to the first fastener 512 on the first limiting block 511, the first strip-shaped hole plays a guiding role to ensure that the first limiting block 511 can move smoothly and linearly.

[0049] Since the nut on the first fastener 511 abuts against the first limiting block 511 to lock it, when releasing the locking relationship with the first limiting block 511, rotating the first fastener 511 for 2 - 3 turns can create a gap between the nut at its top and the first limiting block 511. Therefore, the locking relationship between the quick-release mechanism 5 and the lower mold 2 or the upper mold 4 can be quickly released, and thus the lower mold 2 or the upper mold 4 can be quickly disassembled from the quick-release mechanism 5. Similarly, rotating the first fastener 511 in the reverse direction for 2 - 3 turns can make the nut at its top abut against the first limiting block 511 to quickly complete the assembly of the lower mold 2 or the upper mold 4.

[0050] In a preferred embodiment of the present utility model, handles 14 are horizontally and fixedly arranged on both sides of the lower mold 2 and the upper mold 4.

[0051] In the above solution, it is convenient for the staff to remove the disassembled and assembled lower mold 2 or upper mold 4 by holding the handle 14.

[0052] In a preferred embodiment of the present utility model, at least one guiding hole 13 is vertically and penetratingly formed in the lower mold 2 and the upper mold 4 respectively, and guiding rods 12 which are vertically fixedly arranged on the facing surfaces of the lower base 1 and the upper base 3 and can be penetrated by the lower mold 2 and the upper mold 4 and whose diameters gradually increase and are frustum-shaped from the direction of the lower base 1 to the lower mold 2 or from the direction of the upper base 3 to the upper mold 4 are provided.

[0053] In the above solution, by the combined use of the guiding rod 12 and the guiding hole 13, a guiding effect is achieved, so that the lower mold 2 or the upper mold 4 can be quickly and accurately placed in the two first bases 510.

[0054] Embodiment Two

[0055] The difference between Embodiment Two and Embodiment One lies in:

[0056] In a preferred embodiment of the present utility model, the quick-release mechanism 5 is composed of a second base 520, a second limiting block 521 and a second fastener 522; among them,

[0057] The opposite surfaces of the lower base 1 and the lower mold 2 are respectively horizontally and fixedly provided with two second bases 520 for assembling the lower mold 2 and the upper mold 4 at intervals. The opposite surfaces of the two second bases 520 are respectively partially recessed inward to form guiding grooves adapted to the lower mold 2 or the upper mold 4. The two sides of the lower mold 2 and the upper mold 4 are respectively partially recessed inward to form two second limiting steps 15 adapted to the two guiding grooves on the second bases 520. The lower mold 2 or the upper mold 4 can respectively slide into the two guiding grooves from the ends of the two second bases 520. The ends of the two second bases 520 are movably provided with second limiting blocks 521 capable of blocking the lower mold 2 or the upper mold 4 that slides into the two guiding grooves. Each of the second limiting blocks 521 after movement is locked by the second fastener 522.

[0058] In the above solution, during use, as Figure 8-10 shown, the upper mold 4 or the lower mold 2 is respectively horizontally slid into the two guiding grooves of the two second bases 520 from both ends of the two second bases 520. The two guiding grooves are used to limit the upper mold 4 or the lower mold 2 longitudinally. The two second limiting blocks 521 on the two second bases 520 are moved so that the two second limiting blocks 521 abut against the upper mold base 4 or the lower mold base 2 to limit the upper mold 4 or the lower mold 2 in the transverse direction. The second fastener 522 is used to lock the second limiting block 521 after movement, so as to quickly assemble the upper mold 4 or the lower mold 2 and improve the assembly efficiency.

[0059] In a preferred embodiment of the present invention, the end of each second base 520 is partially recessed inward to form a second limiting groove 16 adapted to the second limiting block 521. A second limiting block 521 capable of abutting against the lower mold 2 or the upper mold 4 is slidably arranged in each second limiting groove 16. The two sides of the lower mold 2 and the upper mold 4 are respectively partially recessed inward to form second limiting steps 15 adapted to the guiding grooves on the second bases 520. A second fixing hole 17 adapted to the second fastener 522 is horizontally opened in each second limiting groove 16. A second strip-shaped hole adapted to the second fastener 522 is opened on each second limiting block 521. The second fastener 522 can pass through the second strip-shaped hole and be screwed into the second fixing hole 17 until the nut of the second fastener 522 abuts against the second limiting block 521 to lock the lower mold 2 or the upper mold 4 that slides into the two guiding grooves on the two second bases 520.

[0060] In the above solution, the second fastener 522 has the same structure as the first fastener 512 and both are bolts.

[0061] During use, the upper mold 4 or the lower mold 2 is horizontally slid into the two guiding grooves of the two second bases 520 from both ends of the two second bases 520 respectively, so that the second limiting steps 15 on both sides of the upper mold 4 or the lower mold 2 abut against the limiting grooves, and the second limiting blocks 521 on the ends of each second base 520 are moved so that the second limiting blocks 521 abut against the upper mold 4 or the lower mold 2, and the second fastener 522 is rotated so that the second fastener 522 rises and falls in the second fixing hole 17 in the second limiting groove 16, so that during the rotation of the second fastener 522, when the nut on its top abuts against the second limiting block 521, the second limiting block 521 is locked, and when the second fastener 522 is rotated in the reverse direction so that the nut on its top leaves the second limiting block 521, the locking of the second limiting block 521 is released, so that the second limiting block 521 can be moved in the reverse direction so that the second limiting block 521 leaves the upper mold 4 or the lower mold 2, so that the upper mold 4 or the lower mold 2 can be quickly disassembled from the quick-release mechanism 5, so as to replace the upper mold 4 and the lower mold 2 of different sizes, so as to realize the airtightness detection of electronic water pumps of different sizes.

[0062] By sliding the upper mold 4 and the lower mold 2 into the two limiting grooves from one end of the two second bases 520 respectively, and moving the second limiting block 521 so that it abuts against the upper mold 4 or the lower mold 2, and locking the second limiting block 521 by the second fastener 522, it can be realized that the upper mold 2 and the lower mold 3 of different sizes can be quickly replaced through the quick-release mechanism 5, so as to be applicable to the airtightness detection of electronic water pumps of different sizes, and the assembly effect is improved.

[0063] Others are the same as in Embodiment 1.

[0064] In summary, the quick-release tooling for airtightness detection of the electronic water pump provided by the present utility model overcomes the problems in the prior art that the disassembly and assembly process is relatively complex, time-consuming and laborious, inconvenient to replace, thereby reducing the disassembly and assembly efficiency and practicability.
