Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a continuous mold series structure. Background Technology

[0002] Progressive dies are ubiquitous in the production of electronics, automotive, and home appliances, used to produce stamped parts of various complex shapes. The working principle of a progressive die involves setting up different forming stations within a single die set. The blank is fed into the die and progressively stamped and deformed sequentially to finally obtain the desired part.

[0003] When encountering complex stamping parts, a longer stamping deformation stroke needs to be designed, which may result in the template being too short and needing to be divided into multiple pieces. However, directly aligning two adjacent templates makes it difficult to guarantee the flatness and consistency of the connection between the two templates, affecting the processing accuracy of the stamped parts.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model discloses a continuous module series structure.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A continuous mold series structure includes a first connector and a second connector, which are respectively disposed at the edges of the template. When two templates are connected, the first connector and the second connector are spliced ​​into one piece. The first connector has a positioning groove 1, and the second connector has a positioning groove 2. When the first connector and the second connector are spliced ​​into one piece, the positioning groove 1 and the positioning groove 2 are connected. A connecting bolt is provided between the first connector and the second connector, and the connecting bolt is located in the positioning groove 1 and the positioning groove 2.

[0008] Furthermore, one end of the positioning groove is provided with a receiving cavity, and the head of the connecting bolt is engaged in the receiving cavity.

[0009] Furthermore, the connector has several positioning screw holes, which penetrate the connector vertically.

[0010] Furthermore, the side of the connector has a groove.

[0011] Furthermore, the second connector includes a protrusion and a stepped portion, which are integrally formed, and the second positioning groove is located on the protrusion.

[0012] Furthermore, the protrusion has several positioning screw holes arranged vertically.

[0013] Furthermore, a locking block is provided on the side of the protrusion, and the locking block is matched with the groove. When connector one and connector two are connected, the locking block is inserted into the groove.

[0014] Furthermore, the stepped portion has several positioning screw holes arranged vertically.

[0015] Furthermore, a nut is threaded onto the end of the connecting bolt away from its head, and the nut abuts against the side of the protrusion.

[0016] Furthermore, the cross-sectional shape of the card block and the groove are both triangular.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. When connecting two adjacent templates, splice connector one and connector two together and lock them together with connecting bolts. Due to the constraint of connector one and connector two, the two templates are in the same plane, which improves the flatness and consistency of the connection between the two templates, reduces the positioning error of the templates, and helps to improve the machining accuracy of the parts.

[0019] 2. Connector 1 and Connector 2 are spliced ​​together as one unit. At this time, Positioning Groove 1 and Positioning Groove 2 are connected as one unit, and the connecting bolt is located in it. The head of the connecting bolt is engaged in the receiving cavity, and the nut connected to the tail of the connecting bolt abuts against the protrusion, thus firmly connecting Connector 1 and Connector 2.

[0020] 3. The locking block and groove fit together to ensure that connector one and connector two can only be successfully connected when they are in the correct position, which helps to reduce positioning errors. Attached Figure Description

[0026] Example:

[0027] A continuous-mode series structure, such as Figure 1 As shown, it includes connector 1 and connector 2. Connector 1 and connector 2 are respectively set at the edge of the template. When connecting two adjacent templates, connector 1 and connector 2 are spliced ​​into one piece to ensure the flatness and consistency of the connection between the two templates.

[0028] like Figure 2 As shown, connector 1 has several positioning screw holes 11. The positioning screw holes 11 extend vertically through connector 1. Screws are inserted into the positioning screw holes 11 to fix connector 1 to the template.

[0029] like Figure 2 As shown, a positioning groove 12 is formed on the top of the connector 1. The groove of the positioning groove 12 is parallel to the length direction of the connector 1. A receiving cavity 121 is provided at one end of the positioning groove 12. A groove 13 is formed on the outward side of the connector 1. The cross-sectional shape of the groove 13 is triangular.

[0030] like Figure 2As shown, connector 2 includes a protrusion 21 and a stepped portion 22, which are integrally formed, with the protrusion 21 located on the outer side and the stepped portion 22 located on the inner side. The protrusion 21 has several vertically arranged positioning screw holes 212, into which screws are screwed to fix connector 2 to the template. Similarly, the stepped portion 22 has several vertically arranged positioning screw holes 221, into which screws are screwed to fix connector 2 to the template.

[0031] like Figure 2 As shown, connector 2 has a positioning groove 213, which is parallel to the length of connector 2 and extends through protrusion 21. The depth and width of positioning groove 213 are the same as those of positioning groove 12. When connector 1 and connector 2 are joined together, positioning groove 12 and positioning groove 213 are connected.

[0032] like Figure 2 As shown, a locking block 211 is provided on the side of the protrusion 21. The locking block 211 is matched with the groove 13, and the cross section of the locking block 211 is also triangular. When the connector 1 and the connector 2 are spliced ​​together, the locking block 211 is inserted into the groove 13 to prevent misalignment between the connector 1 and the connector 2.

[0033] like Figure 2 As shown, a connecting bolt 3 is provided between connector 1 and connector 2, and the connecting bolt 3 is located in positioning groove 12 and positioning groove 213. The head of the connecting bolt 3 is located in the receiving cavity 121 and abuts against the inner wall of the receiving cavity 121. The tail of the connecting bolt 3 is threaded with a nut 31, which abuts against the side of the protrusion 21, thereby locking connector 1 and connector 2 together by the connecting bolt 3.

[0034] Specific work process:

[0035] When assembling the templates, the workers first align the connector 1 and connector 2 at the edges of the two templates one by one, inserting the locking block 211 into the groove 13 to initially position connector 1 and connector 2. Then, the workers adjust the height of connector 1 and connector 2 so that the groove surfaces of positioning groove 12 and positioning groove 213 are at the same height. Next, the connecting bolt 3 is placed into positioning groove 12 and positioning groove 213, with the head of the connecting bolt 3 engaging in the receiving cavity 121, and the tail of the connecting bolt 3 screwed into the nut 31 to lock connector 1 and connector 2. Multiple pairs of connector 1 and connector 2 work together to connect adjacent templates, resulting in good flatness and consistency.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
