Description

Technical Field

[0001] This utility model relates to the field of engine exhaust manifold casting technology, and in particular to corrosion-resistant engine exhaust manifold casting. Background Technology

[0002] The engine exhaust manifold is a key component of the engine exhaust system. It is typically cast from high-temperature resistant alloy materials and has a complex shape and internal channels. The main function of the exhaust manifold is to collect the exhaust gases from each cylinder of the engine and guide them to subsequent treatment devices such as the catalytic converter.

[0003] Some engine exhaust manifolds are made by casting. Engine exhaust manifold castings are the devices used to produce these exhaust manifolds. Existing engine exhaust manifold castings have a relatively simple function, only realizing the casting and molding of engine exhaust manifolds. After the product is demolded, it is necessary to manually spray the release agent into the molding grooves of the upper and lower molds by holding a spray bottle. The manual spraying of the release agent by holding a spray bottle into the upper and lower molds is labor-intensive. In order to solve the above problems, we have proposed this corrosion-resistant engine exhaust manifold casting. Utility Model Content

[0004] The main purpose of this invention is to provide a corrosion-resistant engine exhaust manifold casting, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant engine exhaust manifold casting includes a fixed mold and a moving mold. The fixed mold has a mounting frame on its side wall. A vertical plate is slidably connected to the bottom of the mounting frame. A horizontal plate is provided on the vertical plate. The side wall of the vertical plate is provided with a spraying mechanism for spraying the forming grooves of the fixed mold and the moving mold. The spraying mechanism includes a liquid storage tank set on the side wall of the vertical plate. The liquid storage tank is provided with a liquid pump and a liquid inlet pipe. The inlet and outlet ends of the liquid pump are respectively connected to an inlet pipe and an outlet pipe. The end of the outlet pipe away from the liquid pump is connected to a rotating pipe through a quick connector. The rotating pipe is provided with multiple nozzles communicating with its interior. A drive mechanism for driving the rotating pipe to rotate is provided under the horizontal plate.

[0007] Preferably, the driving mechanism includes a second motor fixedly connected to the lower end of the cross plate, and the rotating tube and the output shaft sidewall of the second motor are respectively provided with a first gear and a second gear.

[0008] Preferably, the side wall of the mounting frame is provided with a controller and a first motor, and the output shaft of the first motor is fixedly connected to a reciprocating lead screw.

[0009] Preferably, a connecting plate is fixedly connected to the lower end of the cross plate, and a plurality of first bolts are provided on the side wall of the connecting plate.

[0010] Preferably, the mounting frame has side plates on both sides, and the side plates have multiple second bolts on their side walls.

[0011] Preferably, the first motor is a servo motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This device is equipped with a spraying mechanism. By slowly pushing the vertical plate towards the fixed mold, the spray nozzle automatically sprays the release agent into the molding tank as it passes between the fixed and moving molds. This eliminates the need for manual spraying of the release agent with a handheld sprayer, thus reducing the labor intensity of the operators. The device is also equipped with a drive mechanism. During the movement of the rotating tube, the rotating tube swings slightly left and right, which can improve the coverage of the release agent spraying. The device is equipped with a first motor. By starting the first motor, the reciprocating screw can be driven to rotate, causing the vertical plate to reciprocate. This eliminates the need for manual pushing of the vertical plate, thereby improving the automation level of the device. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5As shown, the corrosion-resistant engine exhaust manifold casting includes a fixed mold 1 and a moving mold 2. The fixed mold 1 and the moving mold 2 are made of alloy steel or stainless steel containing elements such as chromium and nickel. Chromium can form a dense chromium oxide protective film on the metal surface, preventing oxygen and other corrosive substances from further eroding the metal. Nickel can improve the corrosion resistance and toughness of the alloy. The side wall of the fixed mold 1 is provided with a mounting frame 3. A vertical plate 11 is slidably connected to the bottom of the mounting frame 3. A horizontal plate 18 is provided on the vertical plate 11. The side wall of the vertical plate 11 is provided with a spraying mechanism for spraying the forming groove of the fixed mold 1 and the moving mold 2. The spraying mechanism includes a liquid storage tank 6 set on the side wall of the vertical plate 11. The liquid storage tank 6 is provided with a liquid pump 7 and a liquid inlet pipe 19. The water inlet end and the water outlet end of the liquid pump 7 are respectively connected to a water inlet pipe (the end away from the liquid pump 7 is located near the bottom of the liquid storage tank 6) and a water outlet pipe. The end of the water outlet pipe away from the liquid pump 7 is connected to a rotating pipe 9 through a quick connector 17. The rotating pipe 9 is provided with multiple nozzles 10 that communicate with its interior.

[0022] The horizontal plate 18 is provided with a drive mechanism for driving the rotating tube 9 to rotate. The drive mechanism includes a second motor 13 fixedly connected to the lower end of the horizontal plate 18. The rotating tube 9 and the output shaft sidewall of the second motor 13 are respectively provided with a first gear 15 and a second gear 16. The teeth and meshing details of the first gear 15 and the second gear 16 are not shown in the figure, but in reality, the two mesh with each other.

[0023] In this utility model, the side wall of the mounting frame 3 is provided with a controller 20 and a first motor 5. The output shaft of the first motor 5 is fixedly connected to a reciprocating lead screw 4, which eliminates the need for manual movement of the vertical plate 11, thereby improving the automation level of the device.

[0024] In this utility model, a connecting plate 12 is fixedly connected to the lower end of the horizontal plate 18. The side wall of the connecting plate 12 is provided with a plurality of first bolts 14, so that the horizontal plate 18 can be detachably connected to the vertical plate 11 for convenient transportation.

[0025] In this utility model, the two side walls of the mounting frame 3 are provided with side plates 21, and the side plates 21 are provided with multiple second bolts, so that the mounting frame 3 and the fixed mold 1 can be detachably connected, which facilitates transportation.

[0026] In this invention, the first motor 5 is a servo motor, which makes the forward speed of the nozzle 10 controllable, and the connecting pipe 8 is a corrugated pipe, which allows the rotating pipe 9 to rotate smoothly.

[0027] It should be noted that this utility model is a corrosion-resistant engine exhaust manifold casting. The user slowly pushes the vertical plate 11 towards the fixed mold 1, and the rotating pipe 9 slowly enters the fixed mold 1 and the moving mold 2. The liquid pump 7 is started, and the liquid pump 7 pumps the release agent stored in the liquid tank 6 into the rotating pipe 9. The release agent in the rotating pipe 9 is sprayed out from multiple nozzles 10 (the pipe is equipped with a solenoid valve). Thus, when the nozzles 10 pass through the fixed mold 1 and the moving mold 2, the release agent is sprayed into the molding tank. It is not necessary to manually spray the release agent with a spray bottle, thereby reducing the labor intensity of the operator.

[0028] During the movement of the rotating tube 9, the output shaft of the second motor 13 is started. The output shaft of the second motor 13 drives the rotating tube 9 to swing slightly left and right through the meshing of the first gear 15 and the second gear 16 (the output shaft of the second motor 13 can rotate in both directions), which can improve the spraying and covering effect of the release agent.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
