Description

Technical Field

[0001] The utility model relates to the field of engraving, in particular to a trimming and engraving die. Background Art

[0002] Forging is a machining process that uses a forging press to apply pressure to a metal blank, causing it to plastically deform and produce forgings with defined mechanical properties, shapes, and sizes. Forged products require trimming, which involves removing excess material generated during forging along the product's outer contours. Currently, while the trimming die is trimming the product, an engraving mechanism within the die typically also imprints the product. This engraving mechanism's primary function is to clearly engrave the mark (year / month / day) on the product for traceability. Because the engraving die uses different dies daily or for each batch, the dies must be frequently replaced.

[0003] At present, the existing engraving mechanism for trimming molds is shown in the Chinese utility model "A back panel punching and trimming engraving mold" with patent number CN201720287204.7 (authorization announcement number CN206702064U), which includes an upper mold and a lower mold. The upper mold is provided with an engraving component, which is fixed to the lower surface of the upper mold by screws, so that when the upper mold moves downward, the mold can engrave the back panel workpiece.

[0004] Although the above-mentioned imprinting mechanism can be used for imprinting, it is fixed to the mold by screws. If the imprinting mechanism is frequently replaced, the operation of replacing the imprinting mechanism is relatively troublesome. That is, it is necessary to first remove the upper mold, loosen the screws, remove the old imprinting mechanism, replace it with a new imprinting mechanism, and then fix the new imprinting mechanism to the lower surface of the upper mold with screws, and finally install the upper mold on the mold. Therefore, further improvements are needed for the trimming imprinting mold. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a trimming and engraving mold with a reasonable structure and convenient replacement of the engraving mechanism in response to the above-mentioned existing technical status.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: the trimming and engraving mold includes:

[0007] A mold, comprising an upper mold and a lower mold, wherein the lower mold is used to support the product to be processed, and the upper mold is used to punch and trim the product to be processed; and

[0008] An engraving mechanism is installed on the upper die to engrave the position to be engraved on the product to be processed;

[0009] Its characteristics are:

[0010] A mounting groove for installing the engraving mechanism is provided on the lower surface of the upper mold, and a locking mechanism capable of locking the engraving mechanism is provided at a corresponding position on the lower surface of the upper mold. The locking mechanism includes a locking member that can be extended and retracted relative to the inside and outside of the mounting groove, and the relative locking or unlocking of the locking member is triggered when the actuator located outside the upper mold extends into the locking mechanism.

[0011] In order to enable the locking member of the locking mechanism to be relatively locked or unlocked, preferably, a groove is provided on the side wall of the imprinting mechanism, and when the locking member of the locking mechanism is in the groove, the locking member of the locking mechanism locks the imprinting mechanism, and when the actuator extends into the locking mechanism and triggers the locking member to be located outside the groove, the locking member of the locking mechanism unlocks the imprinting mechanism. That is, when the locking member of the locking mechanism is in the groove, the locking member abuts against the imprinting mechanism through the groove, so that the imprinting mechanism is installed in the mounting groove of the upper mold, preventing the imprinting mechanism from falling out of the mounting groove, thereby locking the imprinting mechanism, and then enabling the imprinting mechanism to imprint the to-be-imprinted position of the product to be processed; when the actuator extends into the locking mechanism and triggers the locking member to be located outside the groove, the locking block releases the imprinting mechanism, and the locking member of the locking mechanism unlocks the imprinting mechanism, so that the imprinting mechanism falls out of the mounting groove under the action of its own weight, thereby removing the imprinting mechanism from the upper mold, and then enabling the imprinting mechanism to be replaced.

[0012] In order to allow the locking member of the locking mechanism to be located within the groove, the locking mechanism preferably further includes a locking seat located on one side of the mounting groove and an elastic member disposed within the locking seat. The locking member is disposed within the locking seat and is capable of extending and retracting along the locking seat. The ends of the elastic member abut against the top wall of the locking seat and the locking member, respectively, and the elastic member causes the locking member to tend to move within the groove. Under the action of the elastic member, the locking member can extend outward within the locking seat to be located within the groove, causing the locking member to abut against the engraving mechanism.

[0013] To enable the locking member to be triggered when the actuator extends into the locking mechanism, the lower surface of the upper mold is preferably further provided with a vertical guide hole for the actuator to enter. The top end of the vertical guide hole communicates with the bottom of the locking seat, and the bottom end of the vertical guide hole communicates with the exterior. The diameter of the vertical guide hole is smaller than that of the locking member. The actuator may be a steel needle that can extend into the locking seat through the vertical guide hole. The actuator can push the locking member, causing it to move out of the groove, thereby unlocking the locking member of the locking mechanism.

[0014] To enable the engraving mechanism to change the engraving font, the engraving mechanism preferably includes an engraving seat and an engraving block. The groove is provided on the side wall of the engraving seat near the locking mechanism. The lower surface of the engraving seat is provided with a slot for inserting the engraving block. The lower end surface of the engraving block is provided with an engraving font that can be engraved at the position to be engraved. When the engraving block is inserted into the engraving seat, the engraving font is exposed to the outside through the slot. The engraving block is detachably connected to the engraving seat. After the engraving mechanism is removed from the upper mold, the engraving font can be changed by replacing the engraving block.

[0015] In order to enable the engraving block to be inserted into the engraving seat, preferably, a clamping block is provided in the slot, and the engraving block is provided with a clamping slot for inserting the clamping block, and the engraving block can be inserted into the engraving seat through the cooperation of the clamping block and the clamping slot.

[0016] Compared with the prior art, the advantages of the present invention are as follows: the trimming and engraving mold is provided with an installation groove on the lower surface of the upper mold. When the engraving mechanism is installed in the installation groove, the locking member of the locking mechanism in the upper mold can lock the engraving mechanism when triggered by the actuator, preventing the engraving mechanism from falling out of the installation groove, thereby allowing the engraving mechanism to engrave the position to be engraved on the product to be processed; or the locking member of the locking mechanism can unlock the engraving mechanism when triggered by the actuator, causing the engraving mechanism to fall out of the installation groove under the action of its own gravity, thereby removing the engraving mechanism from the upper mold and allowing it to be replaced. Therefore, the trimming and engraving mold can simplify the operation of replacing the engraving mechanism and improve the working efficiency of the trimming and engraving mold.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 9 Shown is the best embodiment of the present utility model.

[0028] like Figure 1 and Figure 2 As shown, the trimming and engraving mold of this embodiment includes a mold, which includes an upper mold 2 and a lower mold 3. The lower mold 3 is used to support the product to be processed, and the upper mold 2 punches and trims the product to be processed. The upper mold 2 includes a blade plate 1 for cutting off the flash of the product to be processed and an engraving mechanism 4 for engraving the product to be processed. The lower mold 3 includes a lower support block 31 for placing the product to be processed and fixing the position of the product to be processed.

[0029] like Figures 3-5As shown, the lower surface of the upper mold 2 in this embodiment is provided with a mounting groove 21 for mounting the imprinting mechanism 4. A locking mechanism 5 capable of locking the imprinting mechanism 4 is provided at a corresponding position on the lower surface of the upper mold 2. The locking mechanism 5 includes a locking member 51 that can be extended and retracted relative to the mounting groove 21. The locking member 51 is triggered to lock or unlock when the actuator 6 located outside the upper mold 2 extends into the locking mechanism 5. In this embodiment, a groove 41 is provided on the side wall of the imprinting mechanism 4. When the locking member 51 of the locking mechanism 5 is located within the groove 41, the locking member 51 of the locking mechanism 5 locks the imprinting mechanism 4. When the actuator 6 extends into the locking mechanism 5, the locking member 51 is triggered to be located outside the groove 41, thereby unlocking the imprinting mechanism 4. The locking mechanism 5 of this embodiment also includes a locking seat 52 located on one side of the mounting groove 21 and an elastic member 53 disposed in the locking seat 52. The elastic member 53 of this embodiment is a spring. The locking member 51 is disposed in the locking seat 52 and can extend and retract along the locking seat 52. The two ends of the elastic member 53 respectively abut against the top wall of the locking seat 52 and the locking member 51. The elastic member 53 causes the locking member 51 to have a tendency to move into the groove 41. In addition, the lower surface of the upper mold 2 of this embodiment is further provided with a vertical guide hole 7 for the actuator 6 to enter. The top end of the vertical guide hole 7 is connected to the bottom of the locking seat 52, and the bottom end of the vertical guide hole 7 is connected to the outside. The diameter of the vertical guide hole 7 is smaller than that of the locking member 51. The actuator 6 (such as a steel needle) can extend into the locking seat 52 through the vertical guide hole 7, so that the actuator 6 pushes the locking member 51, causing the locking member 51 to move out of the groove 41, thereby releasing the engraving mechanism 4.

[0030] like Figure 6 and Figure 7 As shown, the imprinting mechanism 4 of this embodiment includes an imprinting seat 42 and an imprinting block 43. A groove 41 is provided on the side wall of the imprinting seat 42 near the locking mechanism 5. A slot 421 is provided on the lower surface of the imprinting seat 42 for inserting the imprinting block 43. The lower end surface of the imprinting block 43 is provided with an imprinting font 431 capable of imprinting the position to be imprinted. When the imprinting block 43 is inserted into the imprinting seat 42, the imprinting font 431 is exposed to the outside through the slot 421. A clamping block 422 is provided in the slot 421, and a slot 432 is provided on the imprinting block 43 for inserting the clamping block 422. The engagement of the clamping block 422 and the slot 432 enables the imprinting block 43 to be inserted into the imprinting seat 42.

[0031] The working process of this embodiment is as follows: when the user needs to replace the imprinting mechanism 4, the user extends the actuating member 6 into the locking seat 52 through the vertical guide hole 7, and the actuating member 6 pushes up the locking member 51, so that the locking member 51 moves out of the groove 41, thereby unlocking the imprinting mechanism 4, and the imprinting mechanism 4 falls off from the mounting groove 21 under the action of its own gravity; then the imprinting block 43 in the imprinting mechanism 4 is pushed to move the imprinting block 43 out of the slot 421 of the imprinting seat 42, and then a new second imprinting block 44 is replaced (the specific structure can be referred to). Figure 8 ) or the third engraving block 45 (the specific structure can refer to Figure 9 ), through the cooperation of the card block 422 and the card slot 442 of the second engraving block 44 or the card slot 452 of the third engraving block 45, the second engraving block 44 or the third engraving block 45 can be inserted into the engraving seat 42, thereby completing the replacement of the engraving font; finally, the replaced engraving mechanism 4 is inserted into the mounting groove 21, and the locking member 51 of the locking mechanism 5 can move along the locking seat 52 under the action of the elastic member 53, and finally the locking member 51 is located in the groove 41, and the locking member 51 of the locking mechanism 5 locks the engraving mechanism 4, that is, the engraving mechanism 4 is installed in the mounting groove 21 of the upper mold 2, and then the engraving mechanism 4 can engrave the position to be engraved on the product to be processed.
