Description

Technical Field

[0001] This application relates to the field of mold processing, and in particular to an ejection and reset structure. Background Technology

[0002] In existing processes, the punch moves downwards to work with the die to stamp the workpiece. After stamping, the workpiece moves upwards with the punch, at which point the stripper plate removes the workpiece from the punch. However, in the current operation, the workpiece sometimes detaches from the punch and remains inside the die, causing the equipment to fail to detect the workpiece and thus halting the machine. To reduce the probability of this happening, this application provides an ejection and reset structure. Utility Model Content

[0003] In order to ensure that the workpiece is removed from the mold and to avoid production line shutdown due to the failure to detect the workpiece, this application provides an ejection and reset structure.

[0004] The ejection and reset structure provided in this application adopts the following technical solution:

[0005] An ejection and reset structure includes a base, a concave membrane disposed on the base, a bracket disposed on the base, and a punch rod disposed on the bracket and located directly above the concave membrane. The top surface of the concave membrane has a groove for the entry of the workpiece. The base has a push rod located in the groove. The base has a reset component for driving the push rod to perform elastic reset. When the punch rod is pressed down, the reset component drives the push rod to move down. When the punch rod moves up, the reset component drives the push rod to return to the groove.

[0006] By adopting the above technical solution, the base is used to install the concave mold, the concave mold and the punch are used to stamp the workpiece, the bracket is used to install the punch, the groove is used for stretching and deforming the workpiece, and the push rod and the reset assembly work together with the operation of the punch to lift the workpiece. When the punch is pressed down, pressing the workpiece into the groove, the push rod moves downward with the workpiece. At this time, the reset assembly is compressed and moves downward with the push rod. When the punch is moved up, the workpiece moves up with the punch. After the reset assembly is depressed, the elastic reset drives the push rod to move up into the groove. When the workpiece does not move up with the punch, the push rod can push the workpiece upward and move the workpiece out of the groove. This application effectively reduces the possibility of the workpiece getting stuck in the groove and affecting the production line; at the same time, it improves the stability of the workpiece output.

[0007] Preferably, the reset assembly includes a positioning rod disposed at the lower end of the top rod, a telescopic rod disposed at the lower end of the positioning rod, and a reset spring sleeved on the telescopic rod. The base is provided with a positioning seat for positioning the lower end of the telescopic rod, and the positioning seat is provided with a through hole for the telescopic rod to move up and down.

[0008] By adopting the above technical solution, the positioning rod improves the driving effect of the return spring on the top rod, the telescopic rod improves the stability of the return spring's movement, the positioning seat improves the stability of the end of the telescopic rod, and the through hole facilitates the telescopic rod to move up and down with the extension and retraction of the return spring; at the same time, the positioning seat cooperates with the positioning rod to position the two ends of the return spring, which facilitates the elastic reset of the return spring.

[0009] Preferably, the lower end of the telescopic rod is provided with a limiting block located on the bottom surface of the positioning seat.

[0010] By adopting the above technical solution, the limiting block improves the stability of the telescopic rod on the positioning seat, reduces the possibility of the end of the telescopic rod detaching from the positioning seat, and at the same time ensures the elasticity of the return spring.

[0011] Preferably, the width of the positioning rod is greater than the width of the return spring.

[0012] By adopting the above technical solution, the width of the positioning rod is larger than the width of the return spring, which makes it easier for the positioning rod to compress the return spring. When the punch presses the workpiece, the workpiece moves down, causing the push rod to move down. The movement of the push rod compresses the positioning rod, causing the return spring to move down. The width of the positioning rod is larger than the width of the return spring, which makes it easier for the positioning rod to control the compression of the return spring.

[0013] Preferably, the groove includes a guide portion, a positioning portion, and a clearance portion sequentially formed from top to bottom, with the width of the guide portion gradually increasing upwards.

[0014] By adopting the above technical solution, the width of the guide part gradually increases upward, which facilitates the entry of the workpiece into the concave mold. The positioning part is used to cooperate with the punch to stretch the workpiece, and the clearance part facilitates the push rod to cooperate with the punch to tighten and position the workpiece.

[0015] Preferably, the width of the avoidance portion gradually increases away from the positioning portion.

[0016] By adopting the above technical solution, the width of the clearance part gradually increases away from the positioning part, which facilitates the ejection of the workpiece by the ejector rod.

[0017] Preferably, the base is provided with a positioning box for positioning the concave membrane, and the top surface of the positioning box has an opening communicating with the groove, the width of the opening being greater than or equal to the maximum width of the guide portion.

[0018] By adopting the above technical solution, the positioning box improves the stability of the concave mold on the base, and the opening is used for the process product to enter the groove. The width of the opening is greater than or equal to the maximum width of the guide part, which facilitates the process product to enter the concave mold.

[0019] Preferably, the width of the top rod is smaller than the width of the positioning part.

[0020] By adopting the above technical solution, the width of the push rod is smaller than the width of the positioning part, which makes it easier for the push rod to enter the groove and eject the workpiece.

[0021] In summary, this application uses a reset assembly and an ejector rod in conjunction with a punch rod to eject the workpiece from the concave mold, ensuring that the workpiece is removed from the groove after the stamping operation is completed; effectively reducing the possibility of the workpiece getting stuck in the groove and improving the stability of the production line.

[0026] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.

[0027] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] This application discloses an ejection and reset structure. (Refer to...) Figure 1The system includes a base 1, a concave mold 2 mounted on the base 1, a bracket 3 fixedly mounted on the top surface of the base 1, a punch 4 mounted on the bracket 3 and located directly above the concave mold 2, and a top rod 6 mounted inside the base 1 and located directly below the punch 4. The top surface of the concave mold 2 has a groove 5 for the workpiece 13 to enter and undergo a stamping operation. The upper end of the top rod 6 is located within the groove 5. A reset assembly 7 is also installed inside the base 1 to control the position of the top rod 6. In this embodiment, before the punch 4 undergoes a stamping operation, the top surface height of the top rod 6 is higher than the top surface height of the concave mold 2. In practice, the top surface height of the top rod 6 can also be flush with the top surface height of the concave mold 2. When the punch rod 4 performs the stamping operation, the punch rod 4 pushes the workpiece 13 into the groove 5. After the workpiece 13 abuts against the push rod 6, it drives the push rod 6 to move downward. At this time, the reset assembly 7 moves downward synchronously. When the punch rod 4 moves upward, the workpiece 13 moves synchronously with the punch rod 4. When the workpiece 13 does not move upward with the punch rod 4, since there is no pressure source above the workpiece 13, the reset assembly 7 drives the push rod 6 to perform a reset operation.

[0029] Reference Figure 1 and Figure 2 The reset assembly 7 includes a positioning rod 71 fixedly installed at the lower end of the top rod 6, a telescopic rod 72 fixedly installed at the lower end of the positioning rod 71, and a reset spring 73 sleeved on the telescopic rod 72. A positioning seat 8 is fixedly installed on the base 1. The positioning seat 8 is used to position the lower end of the telescopic rod 72. The positioning seat 8 has a through hole 9 on the side facing the telescopic rod 72 for the telescopic rod 72 to move up and down. The upper end of the reset spring 73 abuts against the bottom end of the positioning rod 71, and the lower end of the reset spring 73 abuts against the positioning seat 8. When the top rod 6 is subjected to pressure from the upper punch 4, it drives the telescopic rod 72 to move down. At this time, the positioning rod 71 and the positioning seat 8 compress the reset spring 73. When the punch 4 moves up, there is no pressure above, and the reset spring 73 returns to its compressed state, driving the top rod 6 to move up. If the workpiece 13 does not move up with the punch 4, the top rod 6 drives the workpiece 13 to move out of the concave mold 2, which is convenient for the staff to pick up the material and also makes it convenient for the production line to detect the workpiece 13 for the next operation.

[0030] Reference Figure 1 and Figure 3 To improve the telescopic stability of the telescopic rod 72, a limit block 10 is fixedly installed at the lower end of the telescopic rod 72. A positioning seat 8 is located between the limit block 10 and the return spring 73 to ensure the telescopic path of the telescopic rod 72 and prevent the telescopic rod 72 from detaching from the positioning seat 8, thus affecting the stability of the entire ejection and reset structure. The width of the positioning rod 71 is larger than the width of the return spring 73, facilitating compression of the return spring 73 by the positioning rod 71, thereby improving the stability of the return spring 73's compression.

[0031] Reference Figure 2 and Figure 3To improve the stability of the workpiece 13 entering the concave mold 2 for stamping, the groove 5 includes a guide portion 51, a positioning portion 52 located below the guide portion 51, and a clearance portion 53 located below the positioning portion 52. The width of the guide portion 51 gradually increases away from the positioning portion 52. The width of the positioning portion 52 is consistent with the minimum width of the bottom of the guide portion 51 and the size that the workpiece 13 needs to be stamped. The width of the clearance portion 53 gradually increases away from the positioning portion 52 to avoid the push rod 6, so that the push rod 6 and the punch rod 4 can cooperate to position the workpiece 13. The width of the push rod 6 is smaller than the width of the positioning portion 52, so that the push rod 6 can enter the positioning portion 52 and push out the workpiece 13. A positioning box 11 for positioning the concave mold 2 is also installed on the base 1. The top surface of the positioning box 11 has an opening 12 communicating with the groove 5. The width of the opening 12 is greater than or equal to the maximum width of the guide portion 51, so that the punch rod 4 can move down and drive the workpiece 13 into the groove 5.

[0032] The implementation principle of the ejection and reset structure in this embodiment is as follows: A discharge hole is provided on the top surface of the support 3. The width of the discharge hole is larger than the width of the punch 4 and smaller than the width of the workpiece 13. When the punch 4 presses the workpiece 13, the workpiece 13 enters the concave mold 2 for punching and stretching. After the operation is completed, the workpiece 13 moves upward with the punch 4. At this time, the support 3 removes the workpiece 13 from the punch 4. If the workpiece 13 does not move upward with the punch 4, the reset spring 73 changes from the pressure state of the punch 4 to the unpressurized state. The reset spring 73 resets, causing the ejector rod 6 to move upward, ejecting the workpiece 13 from the groove 5. This application effectively avoids the situation where the workpiece 13 remains in the concave mold 2 after punching, improving the stability of the production line operation.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
