Description

Technical Field

[0001] This application relates to the field of mold frame technology, and in particular to a mold frame that is quickly adjustable, lightweight and easy to maintain. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] The published patent with authorization announcement number CN220658950U describes a mold base for a stamping die that is easy to maintain. It includes a lower mold base with a die cavity installed in the center of its top surface. Clamping components are slidably installed at both ends of the lower mold base. Each clamping component includes a fixing post, with a pressure plate rotatably installed in the center of the fixing post. The pressure plate is installed at both ends of the die cavity. An upper mold base is located above the lower mold base, and a punch is slidably installed at the bottom of the upper mold base. The punch is fixed to the bottom of the upper mold base by bolts. This invention features a die cavity installed at the top of the lower mold base and fixed by clamping components, avoiding direct bolt contact with the die cavity. The punch is slidably installed at the bottom of the upper mold base and fixed by bolts, achieving punch positioning. The punch does not directly contact the bolts, and the impact force of the punch will not impact the bolts, thus facilitating the maintenance of both the die cavity and the punch.

[0004] When the above device is implemented, the punch is fixed by bolts to achieve the limit. However, the bolts are prone to stripping their threads after repeated loosening and unloosening during long-term use, which will affect the stability after subsequent tightening and further fail to guarantee the stability of the punch fixation. Therefore, this application proposes a mold frame that is quick to adjust, lightweight and easy to maintain. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a mold frame that is quick to adjust, lightweight and easy to maintain, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a mold frame that is quick-adjustable, lightweight, and easy to maintain, including a lower mold, an upper mold mounted on the top of the lower mold, a lifting component for lifting the upper mold mounted on the outer side of the lower mold, two insert blocks symmetrically mounted on the bottom of the upper mold, and insert holes provided on the inner walls of the two insert blocks, two support frames symmetrically mounted on the top of the lower mold, and square grooves provided on the top of the two support frames, and locking components mounted on the outer walls of the two support frames.

[0007] In a preferred embodiment, the lifting assembly includes a side plate, which is fixed to the outer wall of the lower mold. A positioning frame is fixedly installed on the top of the side plate, and a cylinder is installed on the top of the positioning frame. The output shaft of the cylinder is connected to the top of the upper mold.

[0008] By adopting the above technical solution, the driveable cylinder can pull the upper mold upward, thereby separating the bottom of the movable upper mold from the top of the lower mold, which facilitates the removal of the material formed inside the lower mold.

[0009] In a preferred embodiment, four uprights are symmetrically installed on the top of the lower mold, and each of the four uprights is fitted with an upward push spring along its outer edge. The top ends of the four uprights are inserted into the interior of the upper mold, and both the lower mold and the upper mold are hollow inside.

[0010] By adopting the above technical solution, the four uprights can be used to position the upper mold installed on top of the lower mold, ensuring that the installation position of the upper mold is precisely aligned with the lower mold and will not shift. At the same time, the elastic force of the push spring can be used to support the upper mold, which further facilitates the lifting component to remove the upper mold from the top of the lower mold. The hollow design inside the lower and upper molds can ensure that the lower and upper molds are lightweight and easy to transport.

[0011] In a preferred embodiment, the locking assembly includes a protective cover, which is installed on the outer wall of the support frame. A pin is slidably connected to the inner wall of the protective cover. A fixing plate is fixed to the outer edge of the pin. One end of a return spring is fixedly connected to one side of the fixing plate, and a limit plate is fixedly connected to the other end of the return spring.

[0012] By adopting the above technical solution, the elastic force of the return spring can be used to push the pin near the fixed plate to be stably set on the inner wall of the square groove. Then, the fixed plate and the limiting plate can be used to limit the two ends of the return spring, thereby ensuring that it will not rub against the inner wall of the protective cover. At the same time, the protective cover can be used to protect the fixed plate, the return spring and the limiting plate, ensuring that they are not directly exposed to the outside.

[0013] In a preferred embodiment, the insert block is inserted into the inner wall of the square groove, and the end of the pin near the fixing plate is inserted into the inner wall of the insertion hole.

[0014] By adopting the above technical solution, the insert block can be stably positioned on the inner wall of the square groove using the pin, thereby achieving a stable connection between the lower mold and the upper mold, and further ensuring that the lower mold and the upper mold will not easily separate.

[0015] In a preferred embodiment, a pull plate is fixedly installed on one outer end of the pin.

[0016] By adopting the above technical solution, the user can better slide the pin on the inner wall of the protective cover, making it easier for the user to exert force with their hand. This further facilitates moving the end of the pin close to the fixed plate away from the inner wall of the socket, thereby releasing the locking of the plug.

[0017] In a preferred embodiment, the fixed plate is slidably connected to the inner wall of the protective cover, and the pin is slidably connected to the inner wall of the limiting plate.

[0018] By adopting the above technical solution, the end of the return spring away from the fixed plate can be limited by the limiting plate, thereby ensuring that the return spring will not rub against the inner wall of the protective cover when under force, thus ensuring stability. The fixed plate can move within the inner wall of the protective cover and can be used to squeeze the return spring, thereby moving the position of the pin inserted into the inner wall of the socket.

[0019] The beneficial effects of this application are:

[0020] This type of mold frame is quick-adjustable, lightweight, and easy to maintain. By setting a locking component, the insert block can be stably positioned on the inner wall of the square groove, thereby achieving a stable connection between the lower mold and the upper mold. This further ensures that the lower mold and the upper mold will not easily separate, and there is no need to loosen and unloosen the bolts repeatedly when locking and unlocking, thus facilitating the stability of subsequent locking.

[0021] This mold frame is quick-adjustable, lightweight, and easy to maintain. By driving a cylinder to pull the upper mold upward, the bottom of the upper mold can be separated from the top of the lower mold, making it easier to remove the material formed inside the lower mold, facilitate the maintenance and cleaning of the interior of the lower mold, and make it easy to adjust the distance between the lower mold and the upper mold, thereby increasing the maintenance space.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4 A quick-adjustable, lightweight and easy-to-maintain mold frame includes a lower mold 1, an upper mold 2 mounted on the top of the lower mold 1, a lifting assembly for lifting the upper mold 2 mounted on the outside of the lower mold 1, two insert blocks 8 symmetrically mounted on the bottom of the upper mold 2, and insert holes 9 opened on the inner walls of the two insert blocks 8, two support frames 10 symmetrically mounted on the top of the lower mold 1, and square grooves 11 opened on the top of the two support frames 10, and locking assemblies mounted on the outer walls of the two support frames 10.

[0029] See Figure 1 - Figure 3 The lifting assembly includes a side plate 3, which is fixed to the outer wall of the lower mold 1. A positioning frame 4 is fixedly installed on the top of the side plate 3, and a cylinder 5 is installed on the top of the positioning frame 4. The output shaft of the cylinder 5 is connected to the top of the upper mold 2, so that the cylinder 5 can be driven to pull the upper mold 2 upward, thereby moving the bottom of the upper mold 2 away from the top of the lower mold 1, thus facilitating the removal of the material formed inside the lower mold 1.

[0030] See Figure 1 and Figure 2 Four uprights 6 are symmetrically installed on the top of the lower mold 1, and each of the four uprights 6 is fitted with an upward push spring 7. The tops of the four uprights 6 are inserted into the interior of the upper mold 2. The interiors of both the lower mold 1 and the upper mold 2 are hollow, which allows the four uprights 6 to position the upper mold 2 installed on the top of the lower mold 1, ensuring that the installation position of the upper mold 2 is precisely aligned with the lower mold 1 and will not shift. At the same time, the elastic force of the upward push spring 7 can be used to support the upper mold 2, which further facilitates the lifting assembly to remove the upper mold 2 from the top of the lower mold 1. The hollow design of the interiors of the lower mold 1 and the upper mold 2 ensures that the lower mold 1 and the upper mold 2 are lightweight and easy to transport.

[0031] See Figure 2 and Figure 4The locking assembly includes a protective cover 12, which is installed on the outer wall of the support frame 10. A pin 13 is slidably connected to the inner wall of the protective cover 12. A fixing plate 15 is fixed to the outer edge of the pin 13. One end of a return spring 16 is fixedly connected to one side of the fixing plate 15, and a limiting plate 17 is fixedly connected to the other end of the return spring 16. This allows the elastic force of the return spring 16 to push the pin 13 close to the fixing plate 15 and stably set it on the inner wall of the square groove 11. The fixing plate 15 and the limiting plate 17 can limit the two ends of the return spring 16 respectively, thus ensuring that it will not rub against the inner wall of the protective cover 12. At the same time, the protective cover 12 can protect the fixing plate 15, the return spring 16 and the limiting plate 17, ensuring that they are not directly exposed.

[0032] See Figure 3 and Figure 4 The insert 8 is inserted into the inner wall of the square groove 11, and the end of the pin 13 near the fixed plate 15 is inserted into the inner wall of the insertion hole 9, so that the insert 8 can be stably positioned on the inner wall of the square groove 11 by using the pin 13, thereby achieving a stable connection between the lower mold 1 and the upper mold 2, and further ensuring that the lower mold 1 and the upper mold 2 will not easily separate.

[0033] See Figure 4 A pull plate 14 is fixedly installed on one side of the pin 13, which improves the ease with which the user can pull the pin 13 to slide on the inner wall of the protective cover 12, making it easier for the user to exert force with their hands, and further making it easier to move the end of the pin 13 close to the fixed plate 15 away from the inner wall of the socket 9, thereby releasing the locking of the plug block 8.

[0034] See Figure 4 The fixed plate 15 is slidably connected to the inner wall of the protective cover 12, and the pin 13 is slidably connected to the inner wall of the limiting plate 17. This allows the limiting plate 17 to limit the end of the return spring 16 away from the fixed plate 15, thereby ensuring that the return spring 16 will not rub against the inner wall of the protective cover 12 when under force, thus ensuring stability. The fixed plate 15 can move within the inner wall of the protective cover 12 to press the return spring 16, thereby moving the position of the pin 13 inserted into the inner wall of the socket 9.

[0035] Working principle:

[0036] First, the pin 13 can be used to stably position the insert block 8 on the inner wall of the square groove 11, thereby achieving a stable connection between the lower mold 1 and the upper mold 2. This further ensures that the lower mold 1 and the upper mold 2 will not easily separate. At the same time, pulling the pull plate 14 can cause the pin 13 to slide on the inner wall of the protective cover 12, which makes it easier to move the end of the pin 13 near the fixed plate 15 away from the inner wall of the insertion hole 9, thereby releasing the lock on the insert block 8. Then, the cylinder 5 can be driven to pull the upper mold 2 upward, thereby moving the bottom of the upper mold 2 to separate from the top of the lower mold 1, which makes it easier to remove the material formed inside the lower mold 1.
