Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a trimming structure of a molding mold. Background Art

[0002] A molding die is a mold that is specially used to form and process the overall appearance of a product. During the manufacturing process, the edges of the product often have burrs, unevenness or other undesirable conditions. Generally, trimming equipment is added to the molding die. However, since the grinding structure used to grind the edges and corners of the mold cannot be adjusted, it has great limitations in use, so trimming equipment for repairing local burrs has emerged.

[0003] Although the existing trimming equipment can correct the mold in different directions and angles, such as China Utility Model Patent No. 202221267723.4 discloses a local trimming device for a stamping mold, but the equipment uses a rotating shaft to drive the trimming belt to repair and polish the burrs on the outer surface of the mold. It is more suitable for short molds. When the mold is longer, the corresponding straight length of the trimming belt must also increase. When the trimming belt is longer, it is difficult to ensure that the trimming belt is in a straight state, and it is difficult to ensure that the trimming belt can fit on the outer surface of the mold, and then the mold cannot be trimmed. It is not suitable for molds of a certain length. Therefore, a new technology is proposed. Utility Model Content

[0004] The utility model solves the technical problem that the existing trimming technology is not suitable for a mold with a certain length.

[0005] In order to solve the above technical problems, the utility model provides a technical solution: a molding die trimming structure, including a workstation in a workshop, guide rails with a distance between each other are installed on both sides of the workstation, a slider is slidably mounted on the guide rails, a column is installed on the slider, a push rod is installed between the columns, and two columns and a push rod form a gantry;

[0006] A mounting hole is provided at the center position on the top of the push rod, a cylinder is installed in the mounting hole, the piston end of the cylinder faces downward, a horizontally arranged guide platform is installed on the piston end of the cylinder, the cylinder is located in the middle position of the guide platform, a manually adjustable manual slide is installed under the guide platform, a connecting column is installed under the slider of the manual slide, the manual adjustment of the manual slide drives the connecting column to move linearly to change the position of the connecting column, and a grinding wheel is provided under the connecting column;

[0007] Buffer grooves are provided on opposite sides of the columns, a plurality of positioning springs are fixed in the buffer grooves, a mounting block is fixed between the free ends of the positioning springs, the mounting block is partially located outside the buffer groove, and a grinding belt is installed on the outer surface of the mounting block outside the buffer groove.

[0008] Furthermore, the grinding wheel is of an inverted frustum cone type, that is, a section with a smaller area faces downward, and its outer surface is covered with a grinding layer, so that the grinding angles are more and wider.

[0009] Furthermore, it also includes a baffle plate provided on one side of the work station, which blocks the slider on the guide rail. The mold to be polished can be placed on the work station with one end against the baffle plate. When trimming, the column is moved from the other end so that the grinding belt and grinding wheel contact the outer surface of the mold for grinding and trimming.

[0010] Furthermore, the push rod is located between the grinding belts and does not contact the grinding belts.

[0011] Furthermore, it also includes a material collection cabinet for collecting waste materials arranged under the work station, and a plurality of hollow holes are arranged on the work station, and the waste materials generated by grinding enter the material collection cabinet through the hollow holes.

Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 A molding die trimming structure includes a workbench 1 in a workshop, guide rails 2 are installed on both sides of the workbench 1 at a distance from each other, a slider 3 is slidably mounted on the guide rail 2, a column 4 is installed on the slider 3, a push rod 5 is installed between the columns 4, and two columns 4 and a push rod 5 form a gantry;

[0023] A mounting hole 6 is provided at the center position on the top of the push rod 5, and a cylinder 7 is fixedly installed in the mounting hole 6, and the piston end of the cylinder 7 faces downward. A transversely arranged guide platform 8 is installed on the piston end of the cylinder 7, and the cylinder 7 is located at the middle position of the guide platform 8. A manually adjustable manual slide 9 is installed below the guide platform 8, and a connecting column 10 is installed below the slider of the manual slide 9. The manual adjustment of the manual slide 9 drives the connecting column 10 to move linearly to change the position of the connecting column 10. A grinding wheel 11 is provided below the connecting column 10. The grinding wheel 11 is an inverted frustum type, that is, a smaller section faces downward, and its outer surface is covered with a grinding layer, so that the grinding angle is more and wider;

[0024] Buffer grooves 12 are provided on opposite sides of the column 4, and a plurality of positioning springs 13 are fixed in the buffer grooves 12. A mounting block 14 is fixed between the free ends of the positioning springs 13. Part of the mounting block 14 is located outside the buffer grooves 12. A grinding belt 15 is installed on the outer surface of the mounting block 14 located outside the buffer grooves 12. The push rod 5 is located between the grinding belts 15 and does not contact the grinding belts 15.

[0025] As an embodiment of the utility model, in addition to the above-mentioned structure, it also includes a baffle 16 provided on one side of the work station 1 (the baffle can also be replaced with other fixtures to fix the position of the mold), and the baffle 16 blocks the slider 3 on the guide rail 2.
