Description

Technical Field

[0001] This utility model relates to the field of cutting molds, specifically to a cutting mold with adjustable cutting depth. Background Technology

[0002] A die is a mold used for punching and forming products. In the actual production process, the die works in conjunction with a flat mold that provides pressure. The flat mold applies stable and uniform pressure, and the die head, which is precisely machined on the surface of the die, extrudes and punches the target material. With the help of the pre-set shape and size of the die head, the material is separated and formed into a shape that perfectly matches the contour of the die head. It is widely used in packaging, printing, electronic components and other fields.

[0003] Currently, the die and the cutting head are basically fixed together by welding to ensure strength. This can prevent the cutting head from loosening or falling off during high-frequency punching. However, this also means that the cutting head cannot be flexibly adjusted according to actual processing needs. When punching thin or soft materials, the cutting head is prone to cutting too deep, which can easily damage the processing platform below and cause the cutting edge to be subjected to excessive impact, resulting in chipping or deformation of the cutting edge. This significantly shortens the service life of the cutting head and increases the maintenance and replacement costs of the die.

[0004] Therefore, it is necessary to invent a cutting die with adjustable cutting depth to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable cutting depth die. By setting two sets of support platforms in conjunction with inclined surfaces and grooves, the height of the positioning platform can be adjusted. By adjusting the height of the positioning platform, the downward stroke of the flat die can be limited, thus enabling the punching of products of different thicknesses. At the same time, it can also protect the die head from excessive compression and damage, thereby solving the problem of die head damage when punching thinner products due to a fixed die head height.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cutting depth die, comprising: A mold base, wherein a cutting head is fixedly connected to the upper surface of the mold base; A support mechanism includes a positioning platform slidably connected to the inner wall of a mold base. Measuring components are provided on the front and rear outer walls of the positioning platform. An inclined groove is formed on the inner wall of the positioning platform. A support platform is slidably connected to the inner wall of the mold base. An inclined surface is formed on the top of the support platform. A double-ended threaded rod is rotatably connected through the inner wall of the mold base. A knob is fixedly connected to the left end of the double-ended threaded rod. A threaded sleeve that is threadedly connected to the double-ended threaded rod is fixedly connected to the bottom of the support platform.

[0007] Preferably, the measuring component includes a connecting rod, one end of which is fixedly connected to the side wall of the positioning stage, and the other end of which is fixedly connected to a pointer.

[0008] Preferably, a scale is fixedly connected to the outer walls of the front and rear sides of the mold base.

[0009] Preferably, the sliding direction of the positioning platform is perpendicular to the sliding direction of the support platform.

[0010] Preferably, the inclined surface and the inclined groove have the same inclination angle, and the outer wall of the inclined surface is attached to the inner wall of the inclined groove.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the design of the support mechanism, can limit the downward stroke of the flat die according to the thickness of the product, thus ensuring that the cutter head is not damaged when punching thinner products, providing sufficient protection for the cutter head and thereby improving its service life. Through the setting of the measuring component, the distance between the upper surface of the positioning table and the top of the cutter head can be precisely adjusted according to the thickness of the product, thereby further improving the die-cutting accuracy of the product.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3 The adjustable cutting depth die shown includes a die base 1 and a support mechanism 3; The upper surface of the mold base 1 is fixedly connected to the cutter head 2. The product to be punched is placed on the cutter head 2, and the flat mold is controlled by hydraulic equipment to punch the product downward. At the same time, the product can be punched by the cutter head 2. The support mechanism 3 includes a positioning platform 31, which is slidably connected to the inner wall of the mold base 1. The positioning platform 31 limits the downward stroke of the planar mold, preventing excessive pressing that could damage the cutting head 2. Measuring components 4 are provided on both the front and rear outer walls of the positioning platform 31. An inclined groove 32 is formed on the inner wall of the positioning platform 31. A support platform 33 is slidably connected to the inner wall of the mold base 1. The height of the positioning platform 31 can be adjusted by setting the support platform 33, allowing the distance between its upper surface and the cutting head 2 to be adjusted to the product thickness. The sliding direction of the positioning platform 31 is perpendicular to... The sliding direction of the support platform 33 is such that the top of the support platform 33 is provided with an inclined surface 34, and a double-ended threaded rod 35 is rotatably connected through the inner wall of the mold base 1. A knob 36 is fixedly connected to the left end of the double-ended threaded rod 35. By rotating the double-ended threaded rod 35 through the knob 36, the double-ended threaded rod 35 rotates on the inner wall of the mold base 1. A threaded sleeve 37 that is threadedly connected to the double-ended threaded rod 35 is fixedly connected to the bottom of the support platform 33. When the double-ended threaded rod 35 rotates, it can drive the two sets of threaded sleeves 37 that are threadedly connected to it to move synchronously in opposite directions on the inner wall of the mold base 1.

[0017] like Figure 3 - Figure 4 As shown, the measuring component 4 includes a connecting rod 41. One end of the connecting rod 41 is fixedly connected to the side wall of the positioning platform 31, and the other end of the connecting rod 41 is fixedly connected to a pointer 42. When the positioning platform 31 slides upward, it will drive the connecting rod 41 to move upward synchronously. When the connecting rod 41 moves upward, it will drive the pointer 42 to move upward synchronously. The outer walls of the front and rear sides of the mold base 1 are fixedly connected to a scale 43. When the pointer 42 moves upward, the upward movement distance of the pointer 42 can be observed using the scale 43. In this way, the upward movement distance of the positioning platform 31 can be determined.

[0018] like Figure 2As shown, the inclined surface 34 and the inclined groove 32 have the same inclination angle. The outer wall of the inclined surface 34 is attached to the inner wall of the inclined groove 32. When the two sets of support platforms 33 approach each other, the inclined surface 34 at the top of the support platform 33 will press the inclined groove 32 upward, thereby causing the support platform 33 to push the positioning platform 31 upward. At this time, the positioning platform 31 can slide upward on the inner wall of the mold base 1. When the two sets of support platforms 33 move away from each other, the positioning platform 31 can slide downward and reset by its own gravity.

[0019] The working principle of this utility model is as follows: By rotating the double-threaded rod 35 with knob 36, the double-threaded rod 35 rotates on the inner wall of the mold base 1. At the same time, the double-threaded rod 35 drives the two sets of threaded sleeves 37 connected to it to move synchronously in opposite directions on the inner wall of the mold base 1. At this time, the two sets of threaded sleeves 37 will drive the two sets of support platforms 33 to slide synchronously in opposite directions on the inner wall of the mold base 1. When the two sets of support platforms 33 approach each other, the inclined surface 34 at the top of the support platform 33 will press the inclined groove 32 upward, thereby causing the support platform 33 to push the positioning platform 31 upward. At this time, the positioning platform 31 can slide upward on the inner wall of the mold base 1. At this time, the distance between the upper surface of the positioning platform 31 and the top of the cutter head 2 will gradually decrease, controlling the distance between the upper surface of the positioning platform 31 and the top of the cutter head 2 to be the same as the material thickness. When the flat mold presses the product downward, the cutter head 2 can punch the product. At the same time, the positioning platform 31 can limit the downward stroke of the flat mold, thereby avoiding over-punching and damage to the cutter head 2.

[0020] As the positioning platform 31 slides upward, it drives the connecting rod 41 to move upward synchronously. As the connecting rod 41 moves upward, it drives the pointer 42 to move upward synchronously. As the pointer 42 moves upward, the upward distance of the pointer 42 can be observed using the scale 43. In this way, the upward distance of the positioning platform 31 can be known. By subtracting the upward distance of the positioning platform 31 from the known height of the cutter head 2, the distance between the upper surface of the positioning platform 31 and the top of the cutter head 2 can be obtained. Thus, the height of the positioning platform 31 can be precisely adjusted according to the product thickness.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
