[0025] 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.

[0026] like Figure 1 As shown, this utility model provides a clamping device for casting molds, including a placement plate 1. L-shaped clamping blocks 2 are mirror-slidably connected to the left and right sides of the upper surface of the placement plate 1. Spring plates 4 are fixedly connected to the left and right sides of the upper surface of the placement plate 1. Springs 3 are fixedly connected to the front and back sides of the side of the L-shaped clamping blocks 2 away from the spring plates 4 in the horizontal direction. The end of the spring 3 away from the L-shaped clamping blocks 2 is fixedly connected to the surface of the spring plates 4. A telescopic plate 7 is fixedly connected between the outer surface of the L-shaped clamping blocks 2 in the horizontal direction and the surface of the spring plates 4. A support frame is fixedly connected to the lower surface of the placement plate 1 in a rectangular array. A base 6 is fixedly connected to the lower end of the support frame. A movable component 5 is provided above the base 6. Mounting blocks are fixedly connected to the left and right sides of the base 6. Mounting holes with vertical communication are opened on the front and back sides of the upper surface of the mounting blocks.

[0027] The movable component 5 moves the L-shaped clamping blocks 2 on the left and right sides towards the center, thereby stretching the spring 3 and the telescopic plate 7. When the two L-shaped clamping blocks 2 on the left and right sides move to the appropriate position, the casting mold is clamped and fixed. After processing, when the movable component 5 moves to the appropriate position again, the L-shaped clamping blocks 2 on both sides are released from the casting mold. Due to the elastic effect of the stretched spring 3, the L-shaped clamping blocks 2 move, causing the telescopic plate 7 to retract.

[0028] like Figure 2 - Figure 4As shown, the active component 5 includes a motor 51. The bottom of the motor 51 is fixedly connected to the upper surface of the base 6. The output shaft of the motor 51 is fixedly connected to a gear 52. Gears 53 are meshed on both the left and right sides of the outer surface of the gear 52. A fixing rod 54 is fixedly connected through the middle of the gear 53. The outer surface of the fixing rod 54 passes through the interior of the placement plate 1. The upper surface of the gear 53 overlaps with the lower surface of the placement plate 1. A rubber plate 21 is fixedly connected to the vertical outer surface of the L-shaped clamping block 2. Several semi-circular clamping grooves 22 with vertical and vertical communication are opened on the rear side of the vertical upper surface of the L-shaped clamping block 2. The outer surface of the rubber plate 21 is provided with concave and convex surfaces 24. A tool box 23 is fixedly connected to the horizontal upper surface of the L-shaped clamping block 2. The length of the tool box 23 is the same as the length of the L-shaped clamping block 2. The length of the rubber plate 21 is less than the length of the L-shaped clamping block 2. The size and shape of the several semi-circular clamping grooves 22 are different. The several semi-circular clamping grooves 22 are arranged from large to small.

[0029] When needed, the motor 51 is electrically connected to an external power source via wires to start, thereby driving gear 52 to rotate. The rotation of gear 52 drives gears 53 on both sides to rotate. When gears 53 rotate, they also drive the fixing rod 54 and cam 55 to rotate. The rotation of cam 55 drives the L-shaped clamping blocks 2 on both sides to move and move towards the center, thus clamping and positioning the casting mold. The tool box 23 facilitates the placement of tools. The concave and convex surfaces 24 increase the friction of the casting mold during clamping, thereby improving stability. The rubber plate 21 protects the clamping part of the casting mold during clamping and positioning, preventing damage to the casting mold after clamping. The semi-circular clamping grooves 22 in the L-shaped clamping blocks 2 on both sides facilitate the clamping and fixing of tubular casting molds. The semi-circular clamping grooves 22 are available in different sizes to accommodate different types of tubular casting molds.

[0031] When the casting mold is taken out after the machining is finished, the L-shaped rod 124 is turned over and separated from the inside of the positioning groove 122, the strip-shaped port 123 is provided, so that the workers have a stress point and it is convenient to move the plate 121, and the plate 121 is slidably arranged in the inside of the groove 11 and separated from the inside of the socket 125, so that the phenomenon of the residue on the upper surface of the plate 121 is driven, and the phenomenon of rapid cleaning is facilitated. When installation is needed, the plate 121 is directly pushed into the inside of the groove 11 and inserted into the inside of the socket 125, and then the L-shaped rod 124 is turned over again, so that the L-shaped rod 124 is in contact with the positioning groove 122, thereby limiting the position of the plate 121.

[0032] The working principle of the clamping device of the casting mold will be described below.

[0033] When use is needed, the motor 51 is electrically connected with the external power source through the wire, and is started, so that the gear one 52 is driven to rotate, and the gear two 53, the fixed rod 54 and the cam 55 on the left and right sides are driven to rotate due to the rotation of the gear one 52, so that the L-shaped clamping blocks 2 on the left and right sides are moved and close to the middle, so that the casting mold is clamped and positioned. The tool box 23 is provided, so that the tools are conveniently placed. The concave-convex surface 24 is provided to increase the friction. The rubber plate 21 is provided to have protection when the casting mold is clamped and positioned. The semi-circular clamping groove 22 is provided, so that the tubular type casting mold is conveniently clamped and fixed. When the machining is finished and the residue needs to be cleaned, the L-shaped rod 124 is turned over and separated from the inside of the positioning groove 122, and then the plate 121 is pulled to move and separated from the inside of the socket 125, so that the residue on the upper surface of the plate 121 is driven, and the phenomenon of rapid cleaning is facilitated.
