Description

Technical Field

[0001] The invention relates to the technical field of metal cutting and processing, and in particular to a cutting device for mold manufacturing. Background Art

[0002] Isosceles trapezoidal plates are used to make the concave or convex molds in the mold. This shape helps the material flow along a specific angle during the molding process, thus forming parts with precise dimensions and angles. Isosceles trapezoidal plates are usually cut from a whole rectangular plate. During the cutting process, the plates on both sides of the cutting part need to be fixed and clamped to reduce the vibration of the plate during the cutting process, ensure the accuracy and straightness of the cutting path, and make the cutting edge smoother and neater.

[0003] The Chinese patent application document with publication number CN119260059A discloses a two-end fixed aluminum profile cutting device, including a frame, both sides of the upper end of the frame are connected with end clamping groups, the end clamping groups are used to clamp the two ends of the aluminum profile, the end clamping groups include a fixed frame, the fixed frame is fixed to the end of the frame, a clamping plate for placing the aluminum profile is provided above the fixed frame, the clamping plate is an L-shaped structure, one end of the clamping plate has a convex edge, which can realize the limitation of one side of the aluminum profile. When in use, the two ends of the aluminum profile are placed above the two clamping plates respectively, so that the surface of one side of the aluminum profile fits the convex edge of one end of the clamping plate, and then the cutting position is manually adjusted for cutting; When the above patent application document cuts a rectangular plate into an isosceles trapezoid, since the convex edge cannot move relative to the clamping plate, it can only clamp the plate with fixed shapes at both ends and the clamping position is fixed. However, for the rectangular plate that needs to be cut into an isosceles trapezoid, the clamping assembly needs to clamp one corner of the rectangular plate to facilitate cutting out the waist of the isosceles trapezoid, and also needs to clamp one end of the isosceles trapezoid with a waist to facilitate cutting out the other waist of the isosceles trapezoid. In addition, the orientation of the clamping assembly needs to be changed so that the two cut isosceles trapezoids share one waist to avoid waste of the plate. The clamping assembly in the above patent application cannot meet the fixed clamping requirements of the two ends of the rectangular plate cut into an isosceles trapezoid. Summary of the invention

[0004] The invention provides a cutting device for mold manufacturing, which solves the technical problem that in the process of cutting a rectangular plate into an isosceles trapezoidal part, the plate vibrates due to the two ends of the plate not being fixed and clamped, resulting in uneven cutting edges.

[0005] To solve the above problems, the present invention adopts the following technical solutions: A cutting device for mold manufacturing, comprising a frame, a clamping module for clamping and fixing both ends of a plate, and a cutting module for cutting the plate; The rack is used to carry the plates horizontally; The clamping module includes a stop frame, a baffle and a moving frame. The stop frame is provided with a right-angle slot 1 and a vertical section. The stop frame is slidably mounted on the frame horizontally, and the stop frame is rotatably mounted on the frame around a vertical axis. The stop frame is used to match the two ends of the plate to control the lateral position of the plate; the baffle is slidably mounted on the stop frame, and when the end face of one end of the plate fits with the vertical section, the baffle is used to fit with both sides of the plate to control the longitudinal position of the plate; the moving frame is provided with a right-angle slot 2, and when one corner of one end of the plate is engaged in the right-angle slot 1, the right-angle slot 2 is used to engage the other corner of one end of the plate to control the longitudinal position of one end of the plate; The cutting module comprises a cutting torch, and the cutting torch is used for moving relative to the plate to cut the plate into a plurality of isosceles trapezoidal parts.

[0006] When cutting a rectangular plate into multiple isosceles trapezoids, the vertical section of one of the stop frames fits with the end face of one end of the plate, and the baffle fits with the side faces of both sides of the stop frame; the right-angle slot 1 of the other stop frame fits with one of the right angles at the other end of the plate, and the right-angle slot 2 on the mobile frame fits with the other right angle at the other end of the plate; at this time, the plate is fixed between the stop frame, the baffle and the mobile frame, and the cutting torch starts from the corner point of the plate in the right-angle slot 2 and moves relative to the plate, cutting off one corner of the plate to form a waist of the isosceles trapezoidal part. ; Adjust the stop frame so that the vertical section of the stop frame fits with the end face of the plate at the next corner to be cut, and then adjust the baffle so that the baffle fits with the side faces of the plate. At this time, the plate is re-fixed on the stop frame, and the cutting torch and the plate move relative to each other to cut out an isosceles trapezoidal part. The cutting surface forms another waist of the isosceles trapezoid, which is also a waist of the next isosceles trapezoidal part. The device is flexible to use and can clamp the two ends of the rectangular plate whose shape changes during the cutting process to prevent the plate from vibrating and ensure a smooth cutting edge.

[0007] Furthermore, the baffle is slidably mounted on the stop frame in a direction horizontally and parallel to the vertical section, and the baffle is rotationally mounted on the stop frame around a vertical axis.

[0008] When the stop frame moves to adapt to the two ends of the plate, the baffles move away from each other to avoid hitting the plate; when the stop frame adapts to the two ends of the plate, the baffles approach each other and rotate so that the baffles fit both sides of the plate, increasing the contact area between the plate and the baffles, and further reducing the vibration occurring during the plate cutting process.

[0009] Furthermore, the stop frame is provided with two right-angled slots 1, and the two right-angled slots 1 are symmetrically arranged along a symmetry axis that is horizontal and perpendicular to the vertical section.

[0010] The user can select an appropriate right-angle slot 1 according to actual needs to adapt to different cutting trajectories of the plate.

[0011] Furthermore, the movable frame is slidably assembled on the stop frame along a direction horizontally and perpendicular to the vertical section, and the movable frame is slidably assembled on the stop frame along a side wall horizontally and parallel to the right-angle slot close to the symmetry axis.

[0012] When the right-angle slot 1 is engaged with one corner of one end of a plate of different sizes, the movable frame can be changed according to the position of the other corner of one end of the plate, so that the right-angle slot 2 can be engaged with the other corner of one end of the plate.

[0013] Furthermore, when the other corner of the plate is engaged in the second right-angle slot, the outer circumferential surface of the plate and the inner circumferential surface of the movable frame form a circumferentially closed gap extending vertically for avoiding the cutting torch.

[0014] There is a gap between the outer circumference of the plate in the second right-angle slot and the inner circumference of the movable frame, so that the cutting torch can be placed on a corner point of one corner of the plate in the second right-angle slot.

[0015] Furthermore, the stop frame is longitudinally slidably assembled on the frame.

[0016] The stop frame can move horizontally and longitudinally, and can also rotate around a vertical axis. The stop frame can freely change its position according to actual clamping needs and is flexible to use.

[0017] Furthermore, the cutting torch is assembled on the frame in a longitudinal reciprocating sliding manner.

[0018] The cutting torch slides back and forth longitudinally, and the stop frame slides transversely, so that the cutting torch can cut out the waist of the isosceles trapezoid.

[0019] Furthermore, a plurality of universal ball bearings are arranged on the frame, the spherical rollers of the universal ball bearings are used to support the plate, and a pressure plate is vertically slidably assembled on the stop frame, and the pressure plate is used to fix and clamp the plate with the universal ball bearings in the up and down directions.

[0020] The pressure plate and the universal ball bearing limit the vertical direction of the plate to prevent the plate from moving up and down during the cutting process, further increasing the stability of the plate during cutting.

[0021] The beneficial effects of the present invention are: Adjust the stop frame so that the vertical section of the stop frame is arranged longitudinally, place the plate to be cut on the universal ball bearing, move the baffle so that the baffle fits the two side surfaces of the plate, move the stop frame so that the vertical section of the stop frame fits the end surface of the plate, and determine the starting position of the plate; Move the stop frame close to the cutting torch so that the right-angle slot 1 engages with one corner of one end of the plate, and the moving frame moves so that the right-angle slot 2 engages with the other corner of one end of the plate. At this time, one end of the plate is engaged and fixed by the right-angle slot 1 and the right-angle slot 2, and the other end of the plate is fixed by the vertical cut surface and the stop plate. The plate is fixed in the horizontal direction, and the pressure plate is pressed down until it contacts the top of the plate. The plate is fixed in the vertical direction. The cutting torch is opposite to the corner point of the plate in the right-angle slot 2, and the cutting torch starts cutting. The two stop frames move horizontally at the same time, and the cutting torch moves longitudinally to cut off a corner of the plate. Adjust the stop frame close to one end of the plate to be cut so that the vertical section fits with the inclined surface cut from the plate, rotate the baffles and move them closer to each other so that the baffles fit with the two side surfaces of the plate, move the pressure plate down, fix the plate again, move the two baffles laterally at the same time, and move the cutting torch longitudinally to cut the first isosceles trapezoidal part on the plate; during the entire cutting process, the stop frame, the baffles and the moving frame cooperate with each other to fix and clamp the two ends of the plate that is cut into an isosceles trapezoid and its shape is constantly changing, reduce vibration during the cutting process, and ensure a smooth and flat section.
