Description

Technical Field

[0001] The utility model belongs to the technical field of molds, in particular to a nonferrous metal casting mold which is easy to demould. Background Art

[0002] A non-ferrous metal casting mold that is easy to demold means that during the casting process, the casting can be relatively easily removed from the mold without additional operations or tools. This mold design usually takes the characteristics of non-ferrous metals into consideration.

[0003] According to a publicly disclosed metal casting mold that is easy to demold (publication number: CN 217393660U), it includes an upper mold and a lower mold, and the bottom of the upper mold is provided with four groups of limiting holes, and the limiting holes are internally connected with limiting rods, and the bottom of the limiting rods is installed with the lower mold, and the bottom of the lower mold is installed with a cooling pipe, and the tail end of the cooling pipe extends to the back of the lower mold in a winding manner. When the mold is demolded after shaping, if the mold is not easy to demold, the demolding process may cause damage to the surface or structure of the casting, thereby affecting the quality and integrity of the casting. Through the mutual cooperation between the four groups of limiting holes, limiting rods and other components, it is difficult to make the mold fit tightly to the inner side of the mold box, and it is difficult to reduce the gap between the casting and the mold, and reduce the resistance during demolding, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a nonferrous metal casting mold which is easy to demold. The electric telescopic rod, gear bar 1, gears and other components inside the mold auxiliary equipment cooperate with each other to realize the dynamic electric telescopic rod. When the electric telescopic rod is extended, the gear bar 1 will be driven to move on the top of the bottom plate, and the gear bar 1 will be driven to move to the side away from the electric telescopic rod. When the gear bar 1 moves, it will drive the gear to rotate from left to right. The rotation of the gear from left to right makes the moving tracks of the gear bar 1 and the gear bar 2 form relative motion, drives the support plate and the clamping plate to make relative motion, and clamps the two sides of the mold box. Clamping the mold box can make the mold fit closely to the inner side of the mold box, thereby reducing the gap between the casting and the mold, reducing the resistance during demolding, making it easier for the casting to be separated from the mold, improving the demolding efficiency, and solving the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a nonferrous metal casting mold which is convenient for demoulding, comprising a bottom plate, the bottom of the bottom plate is fixedly connected with a supporting leg, the top of the bottom plate is provided with a mold auxiliary device, the mold auxiliary device comprises an electric telescopic rod, the bottom of the electric telescopic rod is fixedly connected to the top of the bottom plate, one end of the electric telescopic rod is fixedly connected with a gear bar 1, the bottom of the gear bar 1 is slidably connected to the top of the bottom plate, the top of the bottom plate is rotatably connected with a gear, the top of the bottom plate is slidably connected with a gear bar 2, the top of the gear bar 1 is fixedly connected with a support plate, the side of the support plate is fixedly connected with a clamping plate, the top of the bottom plate is fixedly connected with a cylinder, the top of the cylinder is fixedly connected with a rectangular plate, the top of the rectangular plate is fixedly connected with a bracket, the top of the bracket is slidably connected with a pressing plate, and the top of the rectangular plate is slidably connected with a mold box.

[0007] Furthermore, the gear bar 1 is meshed with the gear, and the gear bar 2 is meshed with the gear. There are two support plates and clamping plates, and they are symmetrical along the vertical center axis of the rectangular plate. Starting the electric telescopic rod and extending the electric telescopic rod will drive the gear bar 1 to move on the top of the bottom plate, and drive the gear bar 1 to move to the side away from the electric telescopic rod. The gear bar 1 is meshed with the gear. When the gear bar 1 moves, it will drive the gear to rotate from left to right. The gear is meshed with the gear bar 2. The rotation of the gear from left to right will drive the gear bar 2 to move to the side close to the electric telescopic rod, so that the movement trajectories of the gear bar 1 and the gear bar 2 form relative motion.

[0008] Furthermore, the mold box is located on the displacement track of the clamping plate, the mold box is located at the bottom of the pressure plate, and the side of the mold box is hinged with a hinged plate, which will clamp the two sides of the mold box. Clamping the mold box can make the mold fit tightly to the inner side of the mold box, thereby reducing the gap between the casting and the mold, and reducing the resistance during demolding.

[0009] Furthermore, a thin rod is fixedly connected to the side of the splint, a vertical rod is fixedly connected to the bottom of the thin rod, a triangular block is fixedly connected to the side of the vertical rod, a support plate is fixedly connected to the side of the rectangular plate, an inclined block is slidably connected to the top of the support plate, and a blocking plate is fixedly connected to the side of the inclined block.

The movement of the triangular block will squeeze the inclined block, and the inclined surface of the inclined block will fit with the inclined surface of the triangular block, which will push the inclined block to move. Then the splint keeps moving toward the side of the mold box, which will keep pushing the inclined block. The inclined block drives the blocking plate to move. The blocking plates are located on the other two sides of the mold box. The movement of the blocking plates will block the other two sides to make them more closely fit the shape of the mold.

[0010] Furthermore, the blocking plate is located on the side of the mold box, and two of the blocking plates, thin rods, and triangular blocks are provided, and are symmetrical to each other along the vertical center axis of the rectangular plate. The inclined block drives the blocking plate to move, and the blocking plates are located on the other two sides of the mold box. The movement of the blocking plates will block the other two sides.

[0011] Furthermore, the inclined block is located on the displacement track of the triangular block, the side of the support plate is fixedly connected with a short plate, the side of the short plate is fixedly connected with a spring, and the end of the spring away from the short plate is fixedly connected to the side of the blocking plate.

[0012] Furthermore, the bottom of the supporting leg is fixedly connected with an anti-skid pad, and the top of the supporting plate is slidably connected with a limiting block. The design of the anti-skid pad is conducive to preventing the device from sliding sideways.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model realizes the moving electric telescopic rod through the mutual cooperation between the electric telescopic rod, gear bar 1, gears and other components inside the mold auxiliary equipment. When the electric telescopic rod is extended, it will drive the gear bar 1 to move on the top of the bottom plate, and drive the gear bar 1 to move to the side away from the electric telescopic rod. When the gear bar 1 moves, it will drive the gear to rotate from left to right. The rotation of the gear from left to right makes the moving tracks of gear bar 1 and gear bar 2 form relative motion, driving the support plate and the clamping plate to make relative motion, which will clamp the two sides of the mold box. Clamping the mold box can make the mold fit closely to the inner side of the mold box, thereby reducing the gap between the casting and the mold, reducing the resistance during demolding, making it easier for the casting to be separated from the mold, and improving the demolding efficiency.

[0015] 2. The utility model realizes that the movement of the splint drives the thin rod and the vertical rod to move through the mutual cooperation between the triangular block, the blocking plate, the oblique block and other components inside the mold auxiliary equipment. The movement of the vertical rod drives the movement of the triangular block. The movement of the triangular block squeezes the oblique block. The inclined surface of the oblique block fits with the inclined surface of the triangular block, which pushes the oblique block to move. Then the splint continuously moves toward the side of the mold box, continuously pushing the oblique block. The oblique block drives the blocking plate to move. The blocking plate is located on the other two sides of the mold box. The movement of the blocking plate blocks the other two sides to make it more closely fit the shape of the mold, thereby effectively controlling the gap and pressure distribution between the casting and the mold during the casting process and improving the control performance of demolding.
