Description

Technical Field

[0001] This application belongs to the field of miscellaneous can production technology, specifically relating to a molding die for miscellaneous can production. Background Technology

[0002] In existing technologies, forming molds play a crucial role in the production of miscellaneous cans. They press metal sheets into predetermined shapes to facilitate subsequent processing and production of the cans, thus playing a vital role in the production process. However, the can production molds and related equipment currently available on the market have some shortcomings.

[0003] In existing technologies, to facilitate the subsequent installation of accessories such as the bottom and lid of miscellaneous cans, can production also includes subsequent processes such as stamping coils and stamping feet. Cans with special requirements even require an additional neck stamping process. Currently, the common practice is to transfer the can body, after the ribs are finished, to another machine or use a post-station device to complete the coiling and foot stamping processes. Existing stamping dies can usually only stamp the coils and feet simultaneously, and neck stamping still needs to be completed on another machine. This production mode results in an incoherent production process and low utilization efficiency of dies and equipment.

[0004] Therefore, in order to optimize the production process of miscellaneous cans, improve the efficiency of molds and equipment, reduce production costs, and enhance the continuity and overall efficiency of production, it is now urgent to improve the existing molds used in the production of miscellaneous cans in order to achieve high efficiency, continuity and low cost in the production of miscellaneous cans. Utility Model Content

[0005] In order to solve the technical problems in the prior art, in the production of miscellaneous cans, a single mold for forming cans cannot simultaneously complete the stamping of the coil, the base and the neck, and multiple molds are required to complete the production of miscellaneous cans. This results in long downtime, an uncoordinated production process and low efficiency of molds and equipment. This application proposes a molding die for the production of miscellaneous cans.

[0006] This application adopts the following scheme: a molding die for producing miscellaneous cans, including a base plate, a lower die disposed on the base plate, a shaping mechanism disposed on the base plate and located on the outer periphery of the lower die, and an upper die that can be inserted into the lower die. The base plate is provided with a first molding groove, the upper die is provided with a second molding groove, and the shaping mechanism is provided with a third molding groove. The can body to be molded is sleeved between the lower die and the shaping mechanism. When the upper die is matched and inserted into the lower die, the upper die drives the lower die to press the corresponding positions of the can body to be molded into the first molding groove, the second molding groove, and the third molding groove respectively, so that the corresponding positions of the can body to be molded form rolled edges, foot lines, and neck lines.

[0007] In some feasible embodiments, the upper mold includes a fourth main template and a core disposed on the fourth main template, and the second forming groove is disposed on the inner periphery of the fourth main template.

[0008] In some feasible embodiments, the insert includes a lower insert post disposed on the fourth main template and an upper insert post disposed on the lower insert post. The lower insert post has a quadrilateral cross-sectional shape, the upper insert post has a hexagonal cross-sectional shape, and the cross-sectional area of ​​the lower insert post is larger than that of the upper insert post.

[0009] In some feasible embodiments, the lower mold includes a bottom mold disposed on the base plate, a mold core disposed on the bottom mold, and a top mold disposed on the mold core. When the upper mold is matched and inserted into the lower mold, the upper mold drives the bottom mold to press the corresponding position of the can body to be formed into the first forming groove, the upper mold drives the mold core to press the corresponding position of the can body to be formed into the third forming groove, and the upper mold drives the top mold to press the corresponding position of the can body to be formed into the second forming groove.

[0010] In some feasible embodiments, the bottom mold includes a first main template, first side templates movably disposed on both sides of the first main template, a top block disposed between the first main template and the first side templates, and a first mold hole disposed on the first main template. The first forming groove is disposed on the outer periphery of the bottom mold. When the insert is matched and inserted into the first mold hole, the upper insert pushes the top block, thereby driving the two first side templates to slide away from the first main template in the X direction, so as to press the corresponding position of the can body to be formed into the first forming groove.

[0011] In some feasible embodiments, one end of the top block is disposed on both sides of the first mold hole, and the other end can abut against the two first side templates, and the cross-sectional shape of the first mold hole matches the cross-sectional shape of the upper insert post.

[0012] In some feasible embodiments, the bottom mold further includes a reset spring disposed between the first main template and the first side template. Multiple reset springs are spaced apart along the height direction of the first main template. The reset springs are used to drive the two first side templates to move closer to the first main template.

[0013] In some feasible embodiments, the mold core includes a second main template, second side templates movably disposed on both sides of the second main template, a raised edge disposed on the outer periphery of the second side template, and a second mold hole disposed on the second main template. The third forming groove is disposed on the outer periphery of the raised edge. When the insert is matched and inserted into the second mold hole, the lower insert pusher squeezes and drives the two second side templates to slide away from the second main template in the X direction, so that the raised edge presses the corresponding position of the can body to be formed into the third forming groove.

[0014] In some feasible embodiments, the top mold includes a third main template, third side templates movably disposed on both sides of the third main template, and a third mold hole disposed on the third main template. The second forming groove is disposed on the outer periphery of the third side template. When the insert is matched and inserted into the third mold hole, the lower insert pusher squeezes and drives the two third side templates to slide away from the third main template in the X direction, so as to press the corresponding position of the can body to be formed into the second forming groove.

[0015] In some feasible embodiments, a guide mechanism is also included between the upper mold and the shaping mechanism. The guide mechanism includes a guide post on the upper mold and a guide groove on the shaping mechanism. When the upper mold is inserted into the lower mold, the guide post is inserted into the guide groove.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] This application provides a forming mold for can production, comprising a base plate, a lower mold, a shaping mechanism, and an upper mold that can be inserted into the lower mold. The base plate has a first forming groove, the upper mold has a second forming groove, and the shaping mechanism has a third forming groove. The can body to be formed is fitted between the lower mold and the shaping mechanism. When the upper mold is inserted into the lower mold, the upper mold drives the lower mold to press the corresponding positions of the can body to be formed into the first forming groove, the second forming groove, and the third forming groove, respectively, so that the corresponding positions of the can body to be formed form rolled edges, foot lines, and neck lines. With this structure, the stamping forming of rolled edges, foot lines, and neck lines can be completed in one step without the need for multiple molds, reducing the number of equipment replacements and adjustments, reducing downtime, making the production process more continuous, and significantly improving the utilization efficiency of molds and equipment.

The can body to be molded is fitted between the lower die 2 and the shaping mechanism 3. When the upper die 4 is fitted into the lower die 2, the upper die 4 drives the lower die 2 to press the corresponding positions of the can body to be molded into the first molding groove 5, the second molding groove 6, and the third molding groove 7, respectively, so that the corresponding positions of the can body to be molded form rolled edges, foot lines, and neck lines.

[0031] This application provides a forming mold for can production, comprising a base plate, a lower mold, a shaping mechanism, and an upper mold that can be inserted into the lower mold. The base plate has a first forming groove, the upper mold has a second forming groove, and the shaping mechanism has a third forming groove. The can body to be formed is fitted between the lower mold and the shaping mechanism. When the upper mold is inserted into the lower mold, the upper mold drives the lower mold to press the corresponding positions of the can body to be formed into the first forming groove, the second forming groove, and the third forming groove, respectively, so that the corresponding positions of the can body to be formed form rolled edges, foot lines, and neck lines. With this structure, the stamping forming of rolled edges, foot lines, and neck lines can be completed in one step without the need for multiple molds, reducing the number of equipment replacements and adjustments, reducing downtime, making the production process more continuous, and significantly improving the utilization efficiency of molds and equipment. It has the advantages of compact structure, high equipment utilization rate, and ease of promotion and implementation.

[0032] In this embodiment, the upper mold 4 includes a fourth main template 40 and a core 41 disposed on the fourth main template 40, and the second forming groove 6 is disposed on the inner periphery of the fourth main template 40.

[0033] In this embodiment, the insert 41 includes a lower insert post 410 disposed on the fourth main template 40 and an upper insert post 411 disposed on the lower insert post 410. The lower insert post 410 has a quadrilateral cross-sectional shape, and the upper insert post 411 has a hexagonal cross-sectional shape. The cross-sectional area of ​​the lower insert post 410 is larger than the cross-sectional area of ​​the upper insert post 411.

[0034] In this embodiment, the lower mold 2 includes a bottom mold 20 disposed on the base plate 1, a mold core 21 disposed on the bottom mold 20, and a top mold 22 disposed on the mold core 21. When the upper mold 4 is matched and inserted into the lower mold 2, the upper mold 4 drives the bottom mold 20 to press the corresponding position of the can body to be formed into the first forming groove 5, the upper mold 4 drives the mold core 21 to press the corresponding position of the can body to be formed into the third forming groove 7, and the upper mold 4 drives the top mold 22 to press the corresponding position of the can body to be formed into the second forming groove 6.

[0035] In this embodiment, the bottom mold 20 includes a first main mold 200, first side molds 201 movably disposed on both sides of the first main mold 200, a top block 202 disposed between the first main mold 200 and the first side molds 201, and a first mold hole 203 disposed on the first main mold 200. The first forming groove 5 is disposed on the outer periphery of the bottom mold 20. When the insert 41 is matched and inserted into the first mold hole 203, the upper insert 411 presses the top block 202, thereby driving the two first side molds 201 to slide away from the first main mold 200 in the X direction, so as to press the corresponding position of the can body to be formed into the first forming groove 5.

[0036] In this embodiment, one end of the top block 202 is located on both sides of the first mold hole 203, and the other end can abut against the two first side templates 201. The cross-sectional shape of the first mold hole 203 matches the cross-sectional shape of the upper insert post 411.

[0037] In this embodiment, the bottom mold 20 also includes a reset spring 204 disposed between the first main mold 200 and the first side mold 201. Multiple reset springs 204 are spaced apart along the height direction of the first main mold 200. The reset springs 204 are used to drive the two first side molds 201 to move closer to the first main mold 200.

[0038] In this embodiment, the mold core 21 includes a second main template 210, second side templates 211 movably disposed on both sides of the second main template 210, a protruding edge 212 disposed on the outer periphery of the second side template 211, and a second mold hole 213 disposed on the second main template 210. The third forming groove 7 is disposed on the outer periphery of the protruding edge 212. When the insert core 41 is matched and inserted into the second mold hole 213, the lower insert post 410 squeezes and drives the two second side templates 211 to slide away from the second main template 210 in the X direction, so that the protruding edge 212 presses the corresponding position of the can body to be formed into the third forming groove 7.

[0039] In actual implementation, a reset spring is provided between the second main template and the second side template. Multiple reset springs are spaced apart along the height direction of the second main template. The reset springs are used to drive the second side template to move closer to the second main template.

[0040] In actual implementation, a tension spring groove is provided between the second main template and the second side template, and the reset tension spring is matched and located in the tension spring groove.

[0041] In this embodiment, the top mold 22 includes a third main mold 220, third side molds 221 movably disposed on both sides of the third main mold 220, and a third mold hole 222 disposed on the third main mold 220. The second forming groove 6 is disposed on the outer periphery of the third side mold 221. When the insert 41 is matched and inserted into the third mold hole 222, the lower insert 410 squeezes and drives the two third side molds 221 to slide away from the third main mold 220 in the X direction, so as to press the corresponding position of the can body to be formed into the second forming groove 6.

[0042] In actual implementation, a reset spring is provided between the third main template and the third side template. Multiple reset springs are spaced apart along the height direction of the third main template. The reset springs are used to drive the third side template to move closer to the third main template.

[0043] In actual implementation, a tension spring groove is provided between the third main template and the third side template, and the reset tension spring is matched and set in the tension spring groove.

[0044] In this embodiment, a guide mechanism 8 is also provided between the upper mold 4 and the shaping mechanism 3. The guide mechanism 8 includes a guide post 80 provided on the upper mold 4 and a guide groove 81 provided on the shaping mechanism 3. When the upper mold 4 is inserted into the lower mold 2, the guide post 80 is inserted into the guide groove 81.

[0045] In actual implementation, the specific process of can body forming is as follows: During the production of miscellaneous cans, after the sheet metal material completes the rigging process, the push rod will continue to push the rigging-completed can body to be formed onto the lower mold. At this time, the upper mold will press towards the lower mold.

[0046] When the insert is not inserted into the lower mold, the reset springs on the bottom mold, mold core, and top mold are all in a contracted state. As the insert is gradually inserted, the insert will first drive the third side template to move away from the third main template to fix the can body to be formed on the shaping mechanism. Then the insert will abut against the top block, thereby driving the first side template to move away from the first main template to press the corresponding position of the can body to be formed into the first forming groove on the bottom plate to complete the edge forming and fix the can body to be formed between the shaping mechanism and the lower mold to prevent the can body to be formed from shifting. Finally, the insert is fully inserted into the lower mold, and the insert will drive the second side template to move away from the second main template, driving the protrusion to press the can body to be formed into the third forming groove to complete the neck line forming. At the same time, the upper mold fits into the mold, and the corresponding position of the can body to be formed is pressed into the second forming groove to complete the leg line forming. Then the upper mold begins to retract.

[0047] Furthermore, by dividing the insert into a lower insert post 410 and an upper insert post 411, and designing the cross-sectional shape and area of ​​both, and providing a transition slope on the lower insert post, the first mold hole matches the upper insert post, and the second and third mold holes match the lower insert post. During the insertion of the insert into the lower mold, the first and third side templates can be opened first. During the forming process of the corresponding position of the can body to be formed, the transition surface prevents the lower insert post from fitting with the second mold hole. After ensuring that the can body to be formed is fixed between the forming mechanism and the lower mold, the insert is further inserted into the lower mold, the lower insert post fits with the second mold hole, and the two second side templates are opened, which can effectively prevent the can body to be formed from shifting when the second side templates are opened.

[0048] This application provides a forming mold for can production, comprising a base plate, a lower mold, a shaping mechanism, and an upper mold that can be inserted into the lower mold. The base plate has a first forming groove, the upper mold has a second forming groove, and the shaping mechanism has a third forming groove. The can body to be formed is fitted between the lower mold and the shaping mechanism. When the upper mold is inserted into the lower mold, the upper mold drives the lower mold to press the corresponding positions of the can body to be formed into the first forming groove, the second forming groove, and the third forming groove, respectively, so that the corresponding positions of the can body to be formed form rolled edges, foot lines, and neck lines. With this structure, the stamping forming of rolled edges, foot lines, and neck lines can be completed in one step without the need for multiple molds, reducing the number of equipment replacements and adjustments, reducing downtime, making the production process more continuous, and significantly improving the utilization efficiency of molds and equipment. It has the advantages of compact structure, high equipment utilization rate, and ease of promotion and implementation.
