Description

Technical Field

[0001] The present application relates to the field of stamping dies, and in particular to a 4-cylinder universal die frame for a block die. Background Art

[0002] In the field of industrial production, die stamping is often used to produce thin plates. The die can stamp the edges and middle of the thin plates, thereby cutting the thin plates during stamping, so that the thin plates are stamped into a predetermined shape, with high production efficiency.

[0003] The relevant mold includes an upper mold frame and a lower mold frame. The upper mold frame includes an upper mold base and an upper mold plate. The lower mold frame includes a lower mold base and a lower mold plate. The upper mold base and the lower mold base are arranged parallel to each other. The upper mold plate is fixed on the upper mold base and the lower mold plate is fixed on the lower mold base. The workpiece is placed between the upper mold base and the lower mold plate. The power mechanism drives the upper mold base to fall vertically, so that the upper mold plate and the lower mold plate jointly extrude the workpiece. The protrusions on the upper mold plate and the lower mold plate jointly stamp the workpiece, which can cut the edge of the workpiece and cut holes and grooves of different shapes in the middle of the workpiece, thereby achieving the effect of processing the workpiece.

[0004] The above-mentioned related technical solutions have the following defects: when the upper template of different shapes is replaced on the upper mold base, and the lower template is replaced on the lower mold base, the thickness of the upper template and the lower template changes, and the user needs to adjust the feed amount of the power mechanism so that the upper template and the lower template can extrude and process the workpiece. The adjustment process is time-consuming and labor-intensive, causing inconvenience. Utility Model Content

[0005] In order to enable the upper mold frame and the lower mold frame to maintain high precision and punch the workpiece after the template is replaced, the present application provides a 4-cylinder universal mold frame for the block mold.

[0006] The present application provides a 4-cylinder universal mold frame for a block mold, which adopts the following technical solutions:

[0007] A 4-cylinder universal mold frame for a block mold includes an upper mold frame and a lower mold frame. The upper mold frame includes an upper mold base, multiple upper pads, an upper pad and an upper mold plate. The lower mold frame includes a lower mold base and a lower mold plate. The upper mold base, the upper pad and the lower mold base are parallel to each other. The upper pad is arranged between the upper mold base and the upper pad. One end of the upper pad is detachably connected to the upper mold base, and the other end is detachably connected to the upper pad. The upper mold plate is detachably connected to the upper pad, and the lower mold plate is detachably connected to the lower mold base.

[0008] By adopting the above technical solution, an upper pad is set between the upper die base and the upper pad to create a gap between the upper die base and the upper pad. The upper die base is connected to the power unit, and the upper pad is connected to the upper template. After the user replaces the upper template or the lower template, the distance between the upper template and the upper pad can be adjusted by replacing the upper pad with different thicknesses. After the template is replaced, the thickness of the upper mold frame or the lower mold frame changes. By replacing the upper pad, the relative position of the upper mold frame and the lower mold frame remains unchanged, so that the upper mold frame and the lower mold frame can continue to move relative to each other and punch the workpiece. After the template is replaced, the upper mold frame and the lower mold frame can maintain high precision and punch the workpiece, reducing the steps of measuring and testing the stamping quality and improving efficiency.

[0009] Optionally, the upper pad includes a vertical part and a horizontal part, the vertical part and the horizontal part are perpendicular to each other, the vertical part is detachably connected to the upper mold base, and the horizontal part is detachably connected to the upper pad. A plurality of reinforcing columns are arranged between the upper pads, and the reinforcing columns are cylindrical structures, with one end of the reinforcing column abutting against the upper mold base and the other end abutting against the upper pad.

[0010] By adopting the above technical solution, a reinforcing column is set between the upper pads, so that the reinforcing column abuts between the upper die base and the upper pad, thereby improving the overall structural strength of the upper die base and the upper pad. When the power device drives the upper die base to move, the upper mold plate can squeeze the workpiece. At this time, the reinforcing column plays a supporting role, which can reduce the probability of deformation of the upper die base and the upper pad, thereby improving the workpiece processing quality.

[0011] Optionally, a mounting hole is opened at the center of the reinforcing column, and the mounting hole passes through the reinforcing column. A plurality of lower positioning members are provided on the upper pad, and the lower positioning members are inserted into the mounting hole.

[0012] By adopting the above technical solution, by opening a mounting hole at the center of the reinforcing column, the mounting hole is opened at the center of the end face of the reinforcing column, and by arranging a lower positioning piece on the upper pad, the lower positioning piece can be inserted into the mounting hole of the reinforcing column, thereby reducing the probability of the reinforcing column slipping between the upper mold base and the upper pad, so that multiple reinforcing columns can evenly support the upper mold base and the upper pad.

[0013] Optionally, a plurality of upper positioning members are provided on the surface of the upper mold base, and the positions of the upper positioning members correspond one-to-one to the lower positioning members, and the upper positioning members are used to be inserted into the mounting holes.

[0014] By adopting the above technical solution, an upper positioning piece is set on the surface of the upper mold base, so that the upper positioning piece can be inserted into the mounting hole, and then the upper and lower ends of the reinforcing column are clamped by the positioning piece, so that the reinforcing column can remain vertical relative to the upper mold base and the upper pad, so that the reinforcing column maintains a stable position and provides stable support.

[0015] Optionally, the upper positioning member is a conical structure.

[0016] By adopting the above technical solution, by setting the upper positioning piece to a cone, when installing the reinforcement column, the lower end of the reinforcement column is clamped on the lower positioning piece. When the user lifts the upper pad and the reinforcement column, the upper end of the reinforcement column is abutted against the cone and the cone is inserted into the installation hole, which makes it convenient to insert the upper positioning piece into the installation hole of the reinforcement column.

[0017] Optionally, a blanking hole is provided on the lower die base, and the blanking hole passes through the lower die base.

[0018] By adopting the above technical solution, by opening a blanking hole on the lower die base, when the upper template and the lower template jointly extrude the workpiece and groove and open a hole in the middle of the workpiece, the waste generated on the workpiece can fall through the blanking hole, reducing the steps for users to clean up the waste and enabling efficient processing of multiple workpieces.

[0019] Optionally, a plurality of lower pads are provided on the lower die base, and the lower pads are provided on both sides of the blanking hole, so that a gap is formed between the lower die base and the ground.

[0020] By adopting the above technical solution, lower pads are provided on the lower die base so that the lower pads can lift the lower die base, thereby forming a gap between the lower die base and the ground. When the blanks fall from the blanking hole to between the lower pads, it is convenient for users to clean the blanks.

[0021] Optionally, a plurality of positioning columns are provided on the lower die base, the positioning columns are arranged perpendicular to the lower die base, and a plurality of matching tubes are provided on the upper pad, the positions and sizes of the matching tubes correspond one-to-one to the positioning columns, and the positioning columns are used to be inserted into the matching tubes.

[0022] By adopting the above technical solution, by arranging multiple positioning columns on the lower die base, when the upper die frame falls, the matching tube is first connected to the positioning columns. When the lower die base continues to fall and the upper template and the lower template jointly extrude the workpiece, the upper template and the lower template are subjected to stress, and the upper template and the lower template are prone to relative horizontal slippage, resulting in poor workpiece processing quality. By arranging matching tubes and positioning columns, the probability of horizontal slippage of the upper die frame relative to the lower die frame can be reduced, thereby improving the processing quality.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By setting upper pads between the upper die base and the upper pad, a gap is created between the upper die base and the upper pad. The upper die base is connected to the power unit, and the upper pad is connected to the upper template. After the user replaces the upper template or the lower template, the distance between the upper template and the upper pads can be adjusted by replacing upper pads of different thicknesses. After the template is replaced, the thickness of the upper die frame or the lower die frame changes. By replacing the upper pads, the relative position of the upper die frame and the lower die frame remains unchanged, so that the upper die frame and the lower die frame can continue to move relative to each other and punch the workpiece. After the template is replaced, the upper die frame and the lower die frame can maintain high precision and punch the workpiece, reducing the steps of measuring and testing stamping quality and improving efficiency.

[0025] 2. By setting a reinforcing column between the upper pads, the reinforcing column abuts between the upper die base and the upper pad, thereby improving the overall structural strength of the upper die base and the upper pad. When the power device drives the upper die base to move, the upper plate can squeeze the workpiece. At this time, the reinforcing column plays a supporting role, which can reduce the probability of deformation of the upper die base and the upper pad, thereby improving the workpiece processing quality.

[0026] 3. By setting multiple positioning columns on the lower die base, when the upper die frame falls, the matching tube is first connected to the positioning columns. When the lower die base continues to fall and the upper and lower templates jointly extrude the workpiece, the upper and lower templates are subjected to stress, and the upper and lower templates are prone to relative horizontal slippage, resulting in poor workpiece processing quality. By setting matching tubes and positioning columns, the probability of horizontal slippage of the upper die frame relative to the lower die frame can be reduced, thereby improving processing quality.

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The present application embodiment discloses a 4-cylinder universal mold frame for a block mold, referring to Figure 1 and Figure 2, including an upper mold frame 1, a lower mold frame 2 and multiple reinforcement columns 3. The upper mold frame 1 includes an upper mold base 11, two upper pads 12, an upper pad 13 and an upper mold plate 14. The upper mold base 11 and the upper pad 13 are both flat structures. The upper mold base 11 and the upper pad 13 are arranged parallel to each other. The two upper pads 12 are installed between the upper mold base 11 and the upper pad 13. One end of the upper pad 12 is fixed to the upper mold base 11, and the other end is fixed to the upper pad 13. The upper mold plate 14 is installed on the side surface of the upper pad 13 away from the upper pad 12. The upper mold base 11 is connected to the power mechanism, and the upper mold plate 14 is used to press down onto the lower mold frame 2 to complete the part processing. The reinforcing column 3 is detachably connected between the upper die base 11 and the upper pad 13. The reinforcing column 3 is installed in the space between the two upper pads 12. The reinforcing column 3 is used to improve the structural strength of the upper die frame 1 and reduce the probability of the upper die base 11 and the upper pad 13 being deformed by force, thereby making the upper die frame 1 have higher quality of parts processing.

[0034] Reference Figure 1 and Figure 2 The upper foot 12 includes a vertical portion 121 and a horizontal portion 122. The vertical portion 121 is perpendicular to the horizontal portion 122 and connected to each other. The vertical portion 121 is perpendicular to the upper die base 11, and the horizontal portion 122 is parallel to the upper pad 13 and fits on one side of the upper pad 13. The upper die base 11, the upper foot 12 and the upper pad 13 are detachably connected to each other by bolts. The user can adjust the distance between the upper die base 11 and the upper pad 13 by installing upper foot 12 of different sizes between the upper die base 11 and the upper pad 13. When the user installs upper mold plates 14 of different thicknesses on the upper pad 13, by adjusting the upper foot 12, the upper die frame 1 and the lower die frame 2 can extrude parts and perform processing, reducing the steps of adjusting the relative positions of the upper die frame 1 and the lower die frame 2 and improving work efficiency.

[0035] Reference Figure 1 and Figure 2 The lower mold frame 2 includes a lower mold base 21, lower pads 22, and a lower mold plate 23. The lower mold base 21 is a flat plate structure, parallel to the upper mold base 11. The lower pads 22 are cubic columnar structures and are located on the lower side of the lower mold base 21, creating a gap between the lower mold base 21 and the ground. The lower mold plate 23 is mounted on the top surface of the lower mold base 21. The lower mold plate 23 corresponds to the upper mold plate 14 in position. When the upper mold frame 1 reciprocates in the vertical direction via the power mechanism, the upper mold plate 14 and the lower mold plate 23 can squeeze the components and punch out structures such as holes and grooves in the components.

[0036] Reference Figure 2A plurality of blanking holes 211 are provided on the lower die base 21. When the upper template 14 and the lower template 23 jointly extrude the parts and punch holes on the parts, blanking occurs on the parts. The punched waste can fall into the space between the lower pads 22 through the blanking holes 211, making it convenient for users to collect and clean the waste.

[0037] Reference Figure 2 , a plurality of matching tubes 15 are provided on the upper pad 13, and a plurality of positioning posts 24 are provided on the lower die base 21. The positioning posts 24 are perpendicular to the lower die base 21, and the matching tubes 15 are perpendicular to the upper pad 13. The positions and sizes of the positioning posts 24 correspond one-to-one to the matching tubes 15, and the positioning posts 24 are used to be inserted into the matching tubes 15. When the upper die frame 1 falls, the matching tubes 15 are first slidably connected with the positioning posts 24. At this time, the upper die frame 1 continues to fall, and the upper die plate 14 and the lower die plate 23 can jointly extrude parts. When extruding parts, the upper die frame 1 and the lower die frame 2 are subjected to stress, and the upper die frame 1 is prone to horizontal slippage relative to the lower die frame 2, resulting in poor processing quality and dimensional accuracy of parts. By providing the matching tubes 15 and the positioning posts 24, the probability of horizontal movement of the upper die frame 1 relative to the lower die frame 2 can be reduced, thereby improving the stamping quality of parts.

[0038] Reference Figure 3 and Figure 4 The reinforcing column 3 is a cylindrical structure, and multiple reinforcing columns 3 are equidistantly spaced along a straight line between the upper die base 11 and the upper pad 13. A mounting hole 31 is opened at the center of the reinforcing column 3, and the mounting hole 31 passes through the reinforcing column 3. A plurality of upper positioning members 32 are connected to the upper die base 11, and a plurality of lower positioning members 33 are connected to the upper pad 13. The positions of the upper positioning members 32 and the lower positioning members 33 correspond to each other. By arranging the reinforcing column 3 between the upper positioning members 32 and the lower positioning members 33, the upper positioning members 32 and the lower positioning members 33 are respectively inserted into the two ends of the mounting hole 31, thereby reducing the probability of the reinforcing column 3 slipping between the upper die base 11 and the upper pad 13, facilitating installation, and enabling multiple reinforcing columns 3 to be evenly arranged between the upper die base 11 and the upper pad 13.

[0039] Reference Figure 3 and Figure 4 The upper positioning piece 32 is set to a conical structure. When the upper mold frame 1 is disassembled, the user sets the reinforcement column 3 on the upper pad 13 and inserts the lower positioning piece 33 into the reinforcement column 3. At this time, the upper mold frame 1 is assembled, and the upper end of the reinforcement column 3 is connected to the upper positioning piece 32. By setting the upper positioning piece 32 to a cone, the cone can be easily and quickly slid into the mounting hole 31, thereby improving the efficiency of replacing reinforcement columns 3 of different lengths.

[0040] The implementation principle of the embodiment of the present application is: by setting a reinforcing column 3 between the upper mold base 11 and the upper pad 13, the upper pad 12 is detachably connected between the upper mold base 11 and the upper pad 13. The user can adjust the distance between the upper mold base 11 and the upper pad 13 by replacing the upper pad 12 and the reinforcing column 3, thereby facilitating the adjustment of the gap between the upper template 14 and the lower template 23, so that when the upper template 14 and the lower template 23 jointly extrude the parts, the dimensional accuracy and surface smoothness of the parts are higher.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
