Description

Technical Field

[0001] The utility model relates to the technical field of aluminum casting equipment, in particular to an improved mold core fixing plate. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Molds are extremely widely used in industrial production. The mold can be composed of two molding halves, and the two molding halves are arranged oppositely. When the two molding halves are opened, the so-called molded parts can be taken out, which requires a special centering device to complete.

[0003] For example, the authorization announcement number "CN201030422Y" is named a mold for casting aluminum ingots. Although when the aluminum ingots with a trapezoidal cross-section are packaged, two adjacent aluminum ingots on the same layer are placed upside down with each other, and the trapezoidal grooves and trapezoidal protrusions on the inclined surface engage with each other to lock the two aluminum ingots longitudinally, so that the aluminum ingots will not slip longitudinally, but there is still an existing mold for casting aluminum ingots. In actual use, it is necessary to butt and fit the two mold halves together, and then realize the die-casting of aluminum materials inside the mold. However, since the two mold halves are separate, they need to be temporarily installed and docked during use. This may result in a certain mold gap after the mold is fitted. The mold gap will affect the subsequent die-casting of aluminum materials. In addition, the gap between the molds will also make the upper mold and the lower mold not fit tightly enough, resulting in poor mold clamping and fixing effect of the mold for casting aluminum ingots, which ultimately reduces the working quality of the mold for casting aluminum ingots.

[0004] At the same time, the existing molds for casting aluminum ingots generally adopt a method of tightening and fixing the mold parts by bolts all around, but the bolt tightening method requires multiple bolts to be screwed into the connection between the two molds in sequence to achieve the fixing effect. However, after the mold is used, the operator needs to reversely screw the bolts one by one to remove it. Not only is the process cumbersome and prolongs the use time of the mold for casting aluminum ingots, but it also imposes a burden on manpower and material resources, reducing the convenience of installation of the mold for casting aluminum ingots. Utility Model Content

[0011] Preferably, mold quick installation structures are provided on both sides of the bottom plate;

[0012] The mold quick installation structure includes a crank, a double-headed screw and a coupling;

[0013] The two cranks are rotatably installed on the outer walls of both sides of the base plate, the inner sides of the two cranks are fixedly connected with double-headed screws, the coupling is fixedly installed in the middle of the double-headed screws, the outer threads of the two double-headed screws are sleeved with two threaded blocks, the tops of the two threaded blocks are slidably connected to the base plate, the tops of the two threaded blocks are fixedly installed with fixed plates, and the inner sides of the two fixed plates are movably connected to the outer wall of the lower mold.

[0017] The crank will drive the double-headed screw to rotate inside the base plate, and the threaded blocks connected to the threads on both sides of the rotating double-headed screw will move inward along the double-headed screw for extrusion. At this time, the threaded blocks will drive the fixed plates on both sides to move parallel to the inside of the base plate.

After the mold between the top plate 2 and the bottom plate 1 is closed, the clamping rods 65 on both sides can be pulled along the rotating shaft 61. At this time, the clamping rods 65 will move to the top of the top plate 2. The rotating sleeve 62 is manually rotated and twisted. At this time, the rotating sleeve 62 will pull the threaded column 63 to move downward, and then the bolt column 63 will pull the upper extension shaft 64 to move downward.

The lower ends of the plurality of clamping rods 65 are movably connected to the top of the top plate 2, and the lower ends of the plurality of clamping rods 65 are movably connected to the extension plate 5.

[0027] After the mold is closed between the top plate 2 and the bottom plate 1, the clamping rods 65 on both sides can be pulled along the rotating shaft 61, and the clamping rods 65 will move to the top of the top plate 2. The rotating sleeve 62 can be manually turned and twisted.

At this time, the clamping rod 65 on the inner side of the extension shaft 64 will tighten and fix the top plate 2 above the mold to achieve positioning and installation. The external flip locking structure is used to enable the top plate 2 to drive the lower mold 3 and the lower mold 4 above the bottom plate 1 to achieve positioning and stable mold closing and installation, thereby improving the working quality of the improved mold centering plate.

[0028] See also Figure 1-6A mold quick installation structure 8 is provided on both sides of the bottom plate 1. The mold quick installation structure 8 includes a crank 81, a double-headed screw 84 and a coupling 85.

After the upper mold 4 and the lower mold 3 are fitted and docked, the crank handles 81 on both sides are rotated, and the crank handles 81 will drive the double-headed screw 84 to rotate inside the bottom plate 1. The threaded blocks 82 connected to the threads on both sides of the rotating double-headed screw 84 will move inward along the double-headed screw 84 for extrusion. At this time, the threaded blocks 82 will drive the fixed plates 83 on both sides to move parallel to the inside of the bottom plate 2 until the fixed plates 83 complete the clamping and positioning effect. The inner side of the upper mold 4 and the lower mold 3 is fixedly provided with a die-casting cavity 9, and the inside of the die-casting cavity 9 is used to fill the aluminum casting material.

[0029] After the upper mold 4 and the lower mold 3 are fitted together, the crank handles 81 on both sides are rotated, and the crank handles 81 will drive the double-headed screw 84 to rotate inside the base plate 1. The threaded blocks 82 connected to the threads on both sides of the rotating double-headed screw 84 will move inward along the double-headed screw 84 and be squeezed. At this time, the threaded blocks 82 will drive the fixed plates 83 on both sides to move parallel to the inside of the base plate 2 until the fixed plates 83 complete the clamping and positioning effect.

[0031] Working principle:

[0032] First, after the mold is closed between the top plate 2 and the bottom plate 1, the clamping rods 65 on both sides can be pulled along the rotating shaft 61, and the clamping rods 65 will move to the top of the top plate 2, and the rotating sleeve 62 can be manually turned and twisted, and the rotating sleeve 62 will pull the threaded column 63 downward, and then the bolt column 63 will pull the upper extension shaft 64 downward, and the clamping rod 65 inside the extension shaft 64 will tighten and fix the top plate 2 above the mold to achieve positioning installation;

[0033] Then, after the upper mold 4 and the lower mold 3 are fitted together, the crank handles 81 on both sides are rotated, and the crank handles 81 will drive the double-headed screw 84 to rotate inside the bottom plate 1, and the threaded blocks 82 connected to the threads on both sides of the rotating double-headed screw 84 will move inward along the double-headed screw 84 for extrusion, and then the threaded blocks 82 will drive the fixed plates 83 on both sides to move parallel to the inside of the bottom plate 2 until the fixed plates 83 complete the clamping and positioning effect;

[0034] Finally, the gasket 72 is made of rubber with a soft texture and good cushioning effect. When the top plate 2 drives the upper mold 4 to press down and fit with the lower mold 3, the docking blocks 73 on both sides will fall on the top of the support block 71. The corresponding fit between the support block 71 and the docking block 73 can make the mold centering more accurate and less prone to deviation. The top ends of the two reinforcement seats 74 are fixedly connected to the inner side of the top plate 2. The reinforcement seat 74 is made of aluminum alloy steel to ensure the stability of the fixed docking block 73.
