[0001] The present application relates to the field of cut-to-length technology, and in particular to a device for cutting mold raw materials to length. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". In the production process of some sheet metal molds, it is necessary to cut the mold sheet raw materials;

[0003] Existing cutting devices usually rely on manual operation, and it is difficult to ensure that the length of each cut is exactly the same, which will lead to waste of mold materials and reduced production efficiency. In addition, the manual cutting process requires workers to do repetitive labor for a long time and is inefficient. Therefore, we urgently need to provide a mold material fixed-length cutting device.

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a mold material fixed length cutting device, referring to Figure 1-Figure 3 , including a body 1, a conveyor belt 2 is provided on the inner side of the upper end of the body 1, a gantry 3 is fixedly installed on the middle part of the upper end of the body 1, a double-headed motor 4 is fixedly connected to the middle part of the inner side of the upper end of the gantry 3, and a rotating rod 5 is connected to the output ends of both sides of the double-headed motor 4, and an incomplete gear 7 is fixedly installed on the other end of the rotating rod 5. The double-headed motor 4 is provided to drive the rotating rods 5 at both ends to rotate, so that the incomplete gear 7 rotates, and the outer side of the incomplete gear 7 is meshed with a rack plate 8, and the bottom of the rack plate 8 is fixedly connected with a cutting blade 9. Through the meshing action of the incomplete gear 7 and the rack plate 8, when the incomplete gear 7 rotates, the rack plate 8 drives the cutting blade 9 to move downward, thereby cutting the mold raw material transported by the conveyor belt 2 A guide movable column 10 is fixedly installed on the top of the rack plate 8. The upper end of the guide movable column 10 passes through the gantry 3 and is provided with a limit baffle 11. The guide movable column 10 is set to ensure the stability of the cutting blade 9 and the rack plate 8 when they move up and down, and ensure that the cutting position of the cutting blade 9 is fixed. A reset spring 13 is provided at the bottom of the limit baffle 11. When the teeth of the incomplete gear 7 are disengaged from the rack plate 8, the rack plate 8 drives the cutting blade 9 to quickly reset under the action of the reset spring 13. In this way, the mold raw material can be quantitatively cut under the effect of uniformly conveying the raw material with the conveyor belt 2, which effectively reduces material waste, reduces production costs, reduces labor intensity during manual operation, and improves work efficiency.

[0022] Reference Figure 2 Two connecting seats 6 are fixedly installed on the inner side of the gantry 3, and the middle parts of the outer surfaces of the two rotating rods 5 are rotatably connected to the inner sides of the two connecting seats 6 respectively. The two connecting seats 6 ensure the stability of the two rotating rods 5 during rotation. The upper ends of the two guide movable columns 10 pass through the limit baffle 11 and are threadedly connected with fixing bolts 12, which are convenient for disassembling the limit baffle 11 so that the staff can regularly maintain or replace the reset spring 13 to ensure the long-term use of the device. The two reset springs 13 are respectively sleeved on the outer sides of the two guide movable columns 10. When the rack plate 8 drives the guide movable column 10 to move downward, the limit baffle 11 continuously squeezes the reset spring 13 on its outer side. Therefore, when the incomplete gear 7 is disengaged from the rack plate 8, the reset spring 13 can drive the cutting blade 9 to quickly reset and perform reciprocating cutting operations.

[0023] Reference Figure 1-Figure 3, fixed seats 14 are symmetrically fixedly connected to the upper ends of the body 1 on both sides, and cylinders 15 are installed on the sides of the fixed seats 14. The output ends of the cylinders 15 pass through the fixed seats 14 and are connected to transmission rods 16. The other end of the transmission rod 16 is fixedly connected to a baffle plate 17. The two cylinders 15 can drive the transmission rod 16 to drive the baffle plate 17 to move horizontally, so as to facilitate the adjustment of the spacing between the two baffle plates 17. By setting two baffle plates 17 with adjustable spacing, the shaking and deviation of the raw materials during transportation can be effectively limited, thereby ensuring the accuracy of the raw materials during cutting. At the same time, it can be adapted to limit the positioning of raw materials of different sizes, thereby enhancing the applicability of the device.

[0024] The implementation principle of a fixed-length cutting device for mold raw materials in an embodiment of the present application is as follows: when using the device, first start the two cylinders 15 to drive the transmission rod 16 to adjust the two material baffles 17 to a suitable spacing, and evenly transport the material through the conveyor belt 2, and at the same time start the double-headed motor 4 to drive the two rotating rods 5 to drive the incomplete gear 7 to rotate, so that the incomplete gear 7 drives the rack plate 8 and the cutting blade 9 to move downward to cut the material. At the same time, when the rack plate 8 moves downward, it will drive the guide movable column 10 and the limit baffle 11 to move downward, so that the limit baffle 11 continuously squeezes the two reset springs 13. When the cutting is completed, the incomplete gear 7 and the rack plate 8 are disengaged, and the reset effect of the two reset springs 13 drives the rack plate 8 and the cutting blade 9 to reset quickly, and so on and so forth, thereby quantitatively cutting the raw materials on the conveyor belt 2.
