The utility model sets a sleeve block, a lifting plate and a moving plate, presses the lifting plate to make the sleeve block, the lifting column and the moving plate move downward, then inserts or removes a suitable number of sleeve blocks on the fixed column, then releases the lifting plate and under the elastic force of the spring, the lifting plate and the moving plate move upward until the sleeve block contacts the lifting plate, at which time the sleeve block will block the movement of the lifting plate and the moving plate, and then the molten iron is injected into the liquid storage tank from the liquid inlet pipe. After the injected molten iron contacts the moving plate, it can no longer be injected, and the quantitative work of the molten iron is completed at this time.

[0003] The above technology introduces molten iron into different molds through a liquid outlet pipe. Since the liquid outlet of the liquid outlet pipe cannot be automatically closed, the molten iron discharged from the liquid outlet pipe will be poured on the disc, resulting in a waste of material. Utility Model Content

[0004] The utility model aims to provide an integrated molding device for producing and processing a crankshaft pulley.

[0005] The technical problem solved by the utility model is that the liquid outlet state of the liquid outlet pipe cannot be automatically closed, which will cause the molten iron to be poured at a position outside the mold, thereby causing waste of production materials.

[0006] The utility model can be realized through the following technical scheme: an integrated molding device for crankshaft pulley production and processing, including a support, a liquid storage tank is fixedly installed on the top of the support, molds are slidably arranged on both sides of the top of the support located at the liquid storage tank, an extrusion plate is fixedly installed on the top of the mold, liquid outlet pipes are fixedly connected to both sides of the bottom of the liquid storage tank, a liquid outlet is opened at the bottom of the outer peripheral wall of the liquid outlet pipe, an automatic sealing mechanism is installed at one end of the liquid outlet pipe away from the liquid storage tank, the automatic sealing mechanism is used to cooperate with the moving position of the mold to make the liquid outlet in a closed or open state, and when the mold drives the extrusion plate to extrude the automatic sealing mechanism, the automatic sealing mechanism contacts the closed state of the liquid outlet.

[0007] A further technical improvement of the utility model is that a push-pull plate is rotatably installed on the support at a position between the two molds, a slide groove is provided at the bottom of the push-pull plate, a push-pull rod is fixedly installed at the bottom of the mold, and one end of the push-pull rod away from the mold is slidably connected to the slide groove.

[0008] Furthermore, the shape of the slide groove is elliptical, and the mold is pushed and pulled by cooperating with the sliding of one end of the push-pull rod in the slide groove.

[0009] Furthermore, a liquid inlet pipe is fixedly installed on the top of the liquid storage tank, so that the molten iron can be introduced into the liquid storage tank.

[0010] Furthermore, the automatic sealing mechanism includes a first sliding rod slidingly arranged at one end of the liquid outlet pipe, a first support plate is fixedly installed at the end of the first sliding rod away from the liquid outlet pipe, a second support plate is fixedly installed at the end of the liquid outlet pipe adjacent to the first sliding rod, two second sliding rods are slidingly arranged on the second support plate, one end of the second sliding rod is fixedly connected to one side of the first support plate, a pressure plate is fixedly installed at the other end of the second sliding rod, and a spring is fixedly installed between the pressure plate and one side of the second support plate.

[0011] Furthermore, the outer peripheral wall of the first sliding rod is in contact with the inner peripheral wall of the liquid outlet pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The present application moves the mold to the bottom of the liquid outlet so that the first slide bar slides toward the outside of the liquid outlet pipe to disengage from the closure of the liquid outlet, thereby allowing the molten iron in the liquid outlet pipe to be introduced into the mold through the liquid outlet. Conversely, the first slide bar slides toward the inside of the liquid outlet pipe, and the liquid outlet is closed by the first slide bar. The molten iron in the liquid outlet pipe cannot flow out of the liquid outlet, thereby preventing the molten iron from flowing out of the mold and causing material waste.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-3 As shown, this embodiment provides an integrated molding device for crankshaft pulley production and processing, including a support 1, a liquid storage tank 2 is fixedly installed on the top of the support 1, a liquid inlet pipe 3 is fixedly installed on the top of the liquid storage tank 2, both sides of the outer peripheral wall of the liquid storage tank 2 are fixedly connected with a liquid outlet pipe 4, a liquid outlet port 5 is opened at a position of the outer peripheral wall of the liquid outlet pipe 4 away from the liquid storage tank 2, and an automatic sealing mechanism is installed at one end of the liquid outlet pipe 4 away from the liquid storage tank 2;

[0021] Molds 6 are slidably installed on both sides of the top of the support 1, and a push-pull rod 7 is fixedly installed at the bottom of the mold 6. A push-pull plate 8 is rotatably installed at the center position between the two molds 6 on the support 1. A driving motor for driving the push-pull plate 8 to rotate is installed on the support 1. A slide groove 9 is opened on the push-pull plate 8, and the shape of the slide groove 9 is set to be elliptical. The end of the push-pull rod 7 away from the support 1 is slidably connected with the slide groove 9;

[0022] When the push-pull plate 8 rotates, the push-pull rod 7 will slide in the elliptical chute 9. When one end of the push-pull rod 7 slides from the two ends closest to each other to the two ends farthest apart in the ellipse, the mold 6 is moved in the opposite direction of the liquid storage tank 2 by the push-pull rod 7. Conversely, the mold 6 moves in the direction of the liquid storage tank 2.

[0023] An extrusion plate 10 is fixedly installed on the top of the mold 6, and the automatic closing mechanism includes a first slide bar 11 that is slidably installed through the end of the liquid outlet pipe 4 away from the liquid outlet pipe 4, and the outer peripheral wall of the first slide bar 11 is in contact with the inner peripheral wall of the liquid outlet pipe 4, and the first support plate 12 is fixedly installed on the end of the first slide bar 11 away from the liquid outlet pipe 4, and the second support plate 13 is fixedly installed on the end of the liquid outlet pipe 4 away from the liquid storage tank 2, and the second slide bars 14 are slidably installed on both sides of the second support plate 13, and one end of the second slide bar 14 is fixedly connected to the first support plate 12, and the other end of the second slide bar 14 is fixedly installed with a pressure plate 15, and a spring 16 is fixedly installed between the pressure plate 15 and the second support plate 13;

[0024] When the mold 6 moves in the opposite direction of the liquid storage tank 2 until the mold 6 drives the extrusion plate 10 to squeeze the pressure plate 15, the pressure plate 15 squeezes the spring 16 in the direction of the second support plate 13, so that the spring 16 is in a stressed state, and the pressure plate 15 drives the second slide bar 14 to push the first support plate 12, so that the first support plate 12 drives the first slide bar 11 to move toward the outside of the liquid outlet pipe 4, until the film groove of the mold 6 moves to the bottom of the liquid outlet 5, the first slide bar 11 just breaks away from the blockage of the liquid outlet 5, so that the liquid outlet pipe 4 is The molten iron can flow into the mold 6 through the liquid outlet 5. Conversely, when the mold 6 moves toward the liquid storage tank 2, the mold 6 drives the extrusion plate 10 to disengage the extrusion of the pressure plate 15. At this time, the spring 16 in a stressed state rebounds and pushes the pressure plate 15, so that the pressure plate 15 drives the first pressure plate 15 through the second slide bar 14 to push the first slide bar 11 into the liquid outlet pipe 4. When the spring 16 rebounds to a normal state, the first slide bar 11 just closes the liquid outlet 5 to prevent the molten iron in the liquid outlet pipe 4 from flowing out of the liquid outlet 5.

[0025] When the utility model is in use, an appropriate amount of molten iron is introduced into the liquid storage tank 2 through the liquid inlet pipe 3, and then the push-pull rod 7 is driven to slide in the slide groove 9 by the rotating push-pull plate 8. When one end of the push-pull rod 7 slides in the slide groove 9 to the two ends farthest apart, the extrusion plate 10 squeezes the pressure-bearing plate 15, so that the first slide bar 11 is separated from the closure of the liquid outlet 5, so that the molten iron in the liquid storage tank 2 can flow into the mold 6 through the liquid outlet 5. After an appropriate amount of molten iron is poured into the mold 6, one end of the push-pull rod 7 is driven by the rotating push-pull plate 8 to slide in the slide groove 9 to the two ends closest to the elliptical slide groove 9. At this time, the first slide bar 11 slides into the liquid outlet pipe 4 under the action of the spring 16 rebound. Until the spring 16 rebounds to a normal state, the first slide bar 11 just closes the liquid outlet 5, thereby avoiding the molten iron in the liquid outlet pipe 4 from being poured at a position outside the mold 6, resulting in material waste.
