Abstract
Description
Technical Field
[0001] The present application relates to the field of mold technology, and in particular to a punching mold capable of preventing cutter deviation. Background Art
[0002] Molds are various molds and tools used in industrial production to obtain the required products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, and stretching. In short, the quality of product molding is closely related to the mold.
[0003] Punching dies are a type of die that typically positions the product with a lower die, followed by an upper die pressing down on the product to form a specific shape. However, during the punching process, as the blade presses down, it often tends to tilt outward. This can be further understood as the cutting surface being squeezed during the cutting process, making it difficult to maintain a completely vertical position. As a result, the end face of the final cut product has a certain slope, which is not conducive to high-precision cutting. Utility Model Content
[0004] The purpose of this application is to provide a punching die that prevents the cutter from deflecting, so as to solve at least one of the above-mentioned technical problems.
[0005] In order to solve the above technical problems, the present application provides a punching die with low cost and anti-cutting knife, comprising a base;
[0006] A positioning seat, the positioning seat is provided on the base and has a shape adapted to the workpiece to be cut;
[0007] an anti-drift assembly, wherein one or two anti-drift assemblies are provided and are adapted to be slidably disposed on the base along a first direction. When two anti-drift assemblies are provided, the two anti-drift assemblies are disposed on opposite sides of the positioning seat in the first direction, and the anti-drift assemblies are adapted to be retracted toward the positioning seat along a direction.
[0008] In the above implementation process, the staff places the product to be punched on the positioning seat. The positioning seat ensures the stability of the product, which facilitates subsequent stable punching. In the process of the cutter pressing down, it will be limited by the anti-deviation component. When it is subjected to the cutting extrusion force during the punching process, the anti-deviation component can offset part of the lateral force, so that the cutter can achieve vertical downward cutting more accurately, thereby improving the accuracy of punching.
[0009] Preferably, the anti-drift component includes a limit block and an elastic member;
[0010] One end of the elastic member is connected to the base, and the other end is connected to the limit block, the limit block is suitable for abutting against the side of the cutter, and the elastic member causes the limit block to retract toward the positioning seat;
[0011] In the above implementation process, the limit block is suitable for abutting against the side of the cutter. When the cutter is deflected by the lateral force, the elastic force of the elastic member can offset this part of the lateral force, thereby allowing the cutter to better maintain vertical cutting and improve cutting accuracy.
[0012] Preferably, a sensor is provided on the base along the first direction on the surface opposite to the limit block, and a sensing block is provided on the limit block, and the sensor is used to detect the relative distance between the sensing block and the sensor;
[0013] In the above implementation process, in order to ensure the normal operation of the anti-drift component, this solution further sets up sensors and sensing blocks. When one punching is completed and the next punching is ready, the sensor will sense the position of the sensing block. When it is sensed that the spacing between the sensing blocks is normal, normal punching can be performed. When it is sensed that the spacing between the sensing blocks becomes smaller, it can be determined that the limit block has not been reset normally, and it cannot play a normal limiting role on the cutter during subsequent punching. At this time, an alarm can be issued to facilitate timely shutdown and maintenance by the staff.
[0014] Preferably, a slide rail is provided on the base, a slider is slidably provided on the slide rail, and the limit block is slidably provided on the slider;
[0015] In the above implementation process, the limit block is arranged on the slider, and the slider slides with the slide rail, so that the limit block presents a sliding limit state; it can be understood that the limit block needs to be in a sliding state to cooperate with the elastic part for limiting. If a fixed method is adopted, it may get stuck or fail to limit in place.
[0016] Preferably, V-shaped surfaces are formed on both sides of the slide rail, and the bottom of the slider is adapted to the V-shaped surfaces;
[0017] In the above implementation process, this solution further optimizes the structure of the slide rail and the slider, and realizes further movement limitation through the V-shaped structure, which can make the movement trajectory of the limit block straighter, thereby achieving better and more accurate limiting effect on the cutter.
[0018] Preferably, a blocking block is provided on the base, and the blocking block is used to prevent the cutter from pressing down in an empty material state;
[0019] In the above implementation process, when the material is empty, since the cutter's moving stroke includes the material thickness (i.e., product thickness), in the empty material state, there is no obstruction of the product material thickness, and the cutter will act on the mold. This solution sets a blocking block. When the cutter is performing normal punching, that is, when there is a product, the blocking block will not affect the movement of the cutter. However, in the empty material state, the blocking block will block the cutter to prevent the cutter from damaging the mold.
[0020] Preferably, a stacking protection component is provided on the base;
[0021] The stacking protection assembly includes a support column and a buffer spring;
[0022] In the above implementation process, when not in production, in order to save space, the molds are generally stacked. This solution further provides a stacking protection component to prevent the stacked molds from damaging the main functional structure of the mold, such as the positioning seat, during stacking.
[0023] Compared with the existing technology, the beneficial effect of the present application is that the positioning seat set in this scheme can be used to ensure the stability of the product, thereby facilitating subsequent stable punching; in the process of the cutter pressing down, it will be limited by the anti-deviation component. When it is subjected to the cutting extrusion force during the punching process, the anti-deviation component can offset part of the lateral force, thereby allowing the cutter to achieve vertical downward cutting more accurately, thereby improving the accuracy of punching.

[0038] Example
[0039] A punching die is a type of die that typically positions the product using a lower die, followed by an upper die pressing down on the product to punch and cut it, giving it a specific shape. However, during the punching process, as the blade is pressed down, it often tends to tilt outward. This can be further understood as the cutting surface being squeezed during the cutting process, making it difficult to maintain a completely vertical state. As a result, the end face of the final cut product has a certain slope, which is not conducive to high-precision cutting. To address the above technical issues, this embodiment provides the following technical solutions:
[0040] For details, see Figure 1-5 , this embodiment provides a punching die for preventing a cutter from deflecting, comprising a base 10, a positioning seat 11, and an anti-deflection component 20;
[0041] Specifically, the positioning seat 11 is provided on the base 10 and is formed into a shape adapted to the workpiece to be cut;
[0042] Specifically, one or two anti-drift components 20 are provided and are adapted to be slidably disposed on the base 10 along the first direction. When two anti-drift components 20 are provided, the two anti-drift components 20 are disposed on opposite sides of the positioning seat 11 in the first direction, and the anti-drift components 20 are adapted to be retracted toward the positioning seat 11 along one direction.
[0043] In the above scheme, the staff places the product to be punched on the positioning seat 11. The positioning seat 11 ensures the stability of the product, thereby facilitating subsequent stable punching. During the downward pressing of the cutter, it will be limited by the anti-deviation component 20. When it is subjected to the cutting extrusion force during the punching process, the anti-deviation component 20 can offset part of the lateral force, thereby allowing the cutter to achieve vertical downward cutting more accurately, thereby improving the accuracy of punching.
[0044] For details, see Figure 4-5 , the anti-deviating assembly 20 includes a limit block 21 and an elastic member 22;
[0045] Furthermore, one end of the elastic member 22 is connected to the base 10, and the other end is connected to the limit block 21. The limit block 21 is suitable for abutting against the side of the cutter. The elastic member 22 prompts the limit block 21 to retract toward the positioning seat 11.
[0046] In the above solution, the limit block 21 is suitable for abutting against the side of the cutter. When the cutter is deflected by a lateral force, the elastic force of the elastic member 22 can offset this part of the lateral force, thereby allowing the cutter to better maintain vertical cutting and improve cutting accuracy.
[0047] For details, see Figure 1-2A sensor 31 is provided on the base 10 along the first direction on the opposite surface of the limit block 21, and a sensing block 32 is provided on the limit block 21. The sensor 31 is used to detect the relative distance between the sensing block 32 and the sensor 31;
[0048] In the above scheme, in order to ensure that the anti-drift component 20 works normally, the present scheme further sets a sensor 31 and a sensing block 32. When one punching is completed and the next punching is ready, the sensor 31 will sense the position of the sensing block 32. When it is sensed that the spacing of the sensing blocks 32 is normal, normal punching can be performed. When it is sensed that the spacing of the sensing blocks 32 becomes smaller, it can be determined that the limit block 21 has not been reset normally, and cannot play a normal limiting role on the cutter during subsequent punching. At this time, an alarm can be issued to facilitate timely shutdown and maintenance by the staff.
[0049] For details, see Figure 4-5 , a slide rail 41 is provided on the base 10, a slider 42 is slidably provided on the slide rail 41, and the limit block 21 is slidably provided on the slider 42;
[0050] In the above scheme, the limit block 21 is arranged on the slider 42, and the slider 42 slides with the slide rail 41, so that the limit block 21 is in a sliding limit state; it can be understood that the limit block 21 needs to be in a sliding state to cooperate with the elastic member 22 for limiting. If a fixed method is adopted, it may become stuck or not be limited in place.
[0051] Specifically, V-shaped surfaces are formed on both sides of the slide rail 41, and the bottom of the slider 42 is adapted to the V-shaped surface;
[0052] In the above scheme, this scheme further optimizes the structure of the slide rail 41 and the slider 42, and realizes further movement limitation through the V-shaped structure, which can make the movement trajectory of the limit block 21 straighter, thereby achieving better and more accurate limiting effect on the cutter.
[0053] Specifically, a blocking block 50 is provided on the base 10, and the blocking block 50 is used to prevent the cutter from pressing down in the empty material state;
[0054] In the above scheme, when the material is empty, since the moving stroke of the cutter includes the material thickness (i.e., the product thickness), in the empty material state, there is no obstruction of the product material thickness, and the cutter will act on the mold. This scheme sets a blocking block 50. When the cutter is performing normal punching, that is, when there is a product, the blocking block 50 will not affect the movement of the cutter. However, in the empty material state, the blocking block 50 will block the cutter to prevent the cutter from damaging the mold.
[0055] Specifically, a stacking material protection assembly 60 is provided on the base 10;
[0056] Furthermore, the stacking protection assembly 60 includes a support column 62 and a buffer spring 61;
[0057] In the above scheme, when not in production, in order to save space, the molds are generally stacked. This scheme further provides a stacking protection component 60 to prevent the stacked molds from damaging the main functional structure of the molds, such as the positioning seat 11, when stacking.
[0058] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
[0059] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
