Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a testing fixture for an aluminum alloy steering knuckle mold. Background Technology

[0002] As a key lightweight component of the automotive chassis system, the aluminum alloy steering knuckle's forming process primarily relies on high-pressure casting technology. During the casting process, mold temperature control is crucial to casting quality, production efficiency, and mold life. Therefore, aluminum alloy steering knuckle molds typically incorporate complex cooling water flow systems within the upper and lower molds, precisely regulating mold temperature through circulating cooling water.

[0003] To ensure the reliability and safety of the mold before it is put into formal production, the sealing of its internal cooling water channels must be rigorously tested, i.e., a "water test" must be conducted to check for blockages or leaks. The traditional water test procedure is as follows:

[0004] Temporary inlet and outlet connectors are manually installed at the cooling water inlet and outlet of the upper mold, respectively. Temporary inlet and outlet connectors are also manually installed at the cooling water inlet and outlet of the lower mold. The inlet pipe of the mold testing machine is connected to the inlet connectors of the upper and lower molds, and the outlet pipe of the mold testing machine is connected to the outlet connectors of the upper and lower molds. The mold testing machine is started, and pressurized water or gas is introduced into the cooling water channel to check for leaks. After the test is completed, each connector and pipe is disassembled in sequence.

[0005] However, each mold set, namely the upper mold and the lower mold, requires at least four connectors to be installed. After the test is completed, all of them need to be disassembled. The repetitive manual installation and disassembly is time-consuming and labor-intensive, and the interface on the mold is easily damaged due to the disassembly and assembly of the connectors, which shortens the service life of the mold. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a water testing fixture for aluminum alloy steering knuckle mold that can improve the water testing efficiency and the accuracy of test results, save time and effort, and avoid mold damage.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A testing fixture for an aluminum alloy steering knuckle mold includes a fixture base plate. A positioning block and a limiting block are fixedly installed at both ends of one side of the fixture base plate. The positioning block has a right-angle positioning opening, and the limiting surface of the limiting block and one of the positioning surfaces of the positioning block are located in the same plane.

[0009] A water inlet bracket and a water return bracket are fixedly installed on the other side of the tooling base plate. Two water inlet test blocks are provided on one side of the water inlet bracket, and two water return test blocks are provided on one side of the water return bracket. The upper water inlet test block and the water return test block are fixedly installed on the upper plate, and the lower water inlet test block and the water return test block are fixedly installed on the lower plate. An upper cylinder and a lower cylinder are fixedly installed on the water inlet bracket and the water return bracket respectively on the upper plate and the lower plate. The piston rod of the upper cylinder is fixedly connected to the upper plate, and the piston rod of the lower cylinder is fixedly connected to the lower plate. The water inlet test block is connected to the water inlet pipe of the mold water testing machine through a water inlet connector, and the water return test block is connected to the water return pipe of the mold water testing machine through a water return connector.

[0010] Thus, the mold includes an upper mold and a lower mold, both of which are rectangular blocks. The upper mold and the lower mold are placed on the tooling base plate. The corners of the upper mold and the lower mold are located in the right-angle positioning holes and are in contact with the two positioning surfaces of the right-angle positioning holes. The upper mold and the lower mold are in contact with the limiting surfaces of the limiting blocks to complete the positioning of the upper mold and the lower mold. At the same time, the positioning blocks and the limiting blocks provide support for the upper mold and the lower mold. Two water inlet test blocks are directly opposite the water inlets of the upper mold and the lower mold, respectively, and two water return test blocks are directly opposite the water return outlets of the upper mold and the lower mold, respectively. During the water test, the upper and lower cylinders drive the upper and lower plates to move, so that the water inlet test block is in contact with the water inlet and the water return test block is in contact with the water return outlet. The mold water tester is started, and water is introduced into the cooling water channel through the water inlet pipe, water inlet connector and water inlet test block. Water is returned through the water return test block, water return connector and water return pipe to achieve the water test. After the test is completed, the upper and lower cylinders drive the upper and lower plates to move, so that the water inlet test block and the water return test block are separated from the water inlet and water return outlet respectively.

[0011] By setting up inlet and outlet water test blocks, automatic pressing and separation with the inlet and outlet of the mold is achieved, eliminating the need for manual installation of connectors, avoiding damage to the mold, and improving the efficiency of water testing.

[0012] Preferably, both the inlet test block and the return test block are provided with sealing grooves, and sealing rings are fixedly installed in the sealing grooves.

[0013] Preferably, reinforcing ribs are fixedly installed between the water inlet bracket, the water return bracket, and the tooling base plate.

[0014] Preferably, a reinforcing rib is fixedly installed between the limiting block and the tooling base plate.

[0015] Preferably, a reinforcing rib is fixedly installed between the positioning block and the tooling base plate.

[0016] In summary, this utility model has the advantages of improving the efficiency of mold testing and the accuracy of test results, saving time and effort, and avoiding mold damage. Attached Figure Description

In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0023] like Figure 1-5 As shown, a testing fixture for an aluminum alloy steering knuckle mold includes a fixture base plate 1. A positioning block 2 and a limiting block 3 are fixedly installed at both ends of one side of the fixture base plate. The positioning block has a right-angle positioning opening 4, and the limiting surface 5 of the limiting block and one of the positioning surfaces of the positioning block are located in the same plane.

[0024] On the other side of the tooling base plate, a water inlet bracket 6 and a water return bracket 7 are fixedly installed. Two water inlet test blocks 8 are provided on one side of the water inlet bracket, and two water return test blocks 9 are provided on one side of the water return bracket. The upper water inlet test block and water return test block are fixedly installed on the upper plate 10, and the lower water inlet test block and water return test block are fixedly installed on the lower plate 11. The water inlet bracket and water return bracket are respectively fixedly installed with an upper cylinder 12 and a lower cylinder 13 on the upper and lower plates, respectively. The piston rod of the upper cylinder is fixedly connected to the upper plate, and the piston rod of the lower cylinder is fixedly connected to the lower plate. The water inlet test block is connected to the water inlet pipe of the mold water testing machine through a water inlet connector 14, and the water return test block is connected to the water return pipe of the mold water testing machine through a water return connector 15.

[0025] Thus, the mold includes an upper mold 16 and a lower mold 17, both of which are rectangular blocks. The upper and lower molds are placed on the tooling base plate, with the corners of the upper and lower molds located inside the right-angle positioning opening and in contact with the two positioning surfaces of the right-angle positioning opening. The upper and lower molds are in contact with the limiting surfaces of the limiting blocks to complete the positioning of the upper and lower molds. At the same time, the positioning blocks and limiting blocks provide support for the upper and lower molds. Two water inlet test blocks are directly opposite the water inlets of the upper and lower molds, respectively, and two water return test blocks are directly opposite the water return outlets of the upper and lower molds, respectively. During the water test, the upper and lower cylinders drive the upper and lower plates to move, so that the water inlet test block is in contact with the water inlet and the water return test block is in contact with the water return outlet. The mold water tester is started, and water is introduced into the cooling water channel through the water inlet pipe, water inlet connector and water inlet test block. Water is returned through the water return test block, water return connector and water return pipe to achieve the water test. After the test is completed, the upper and lower cylinders drive the upper and lower plates to move, so that the water inlet test block and the water return test block are separated from the water inlet and water return outlet respectively.

[0026] By setting up inlet and outlet water test blocks, automatic pressing and separation with the inlet and outlet of the mold is achieved, eliminating the need for manual installation of connectors, avoiding damage to the mold, and improving the efficiency of water testing.

[0027] The mold testing machine is an existing setup. Its inlet and outlet pipes are connected to the inlet and outlet connectors via quick-release couplings. The inlet and outlet connectors are integrated with the inlet and outlet test blocks, respectively, for ease of use.

[0028] During implementation, both the inlet and outlet water test blocks are equipped with sealing grooves, and sealing rings 18 are fixedly installed inside the sealing grooves. This prevents water leakage between the inlet and outlet water test blocks and the mold, improving the accuracy of the side test results.

[0029] During implementation, reinforcing ribs are fixedly installed between the water inlet support, the water return support, and the tooling base plate to improve the deformation resistance of the water inlet support and the water return support.

[0030] During implementation, reinforcing ribs are fixedly installed between the limiting block and the tooling base plate to improve the installation reliability of the limiting block.

[0031] During implementation, reinforcing ribs are fixedly installed between the positioning block and the tooling base plate to improve the installation reliability of the positioning block.

[0032] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
