Description

Technical Field

[0001] The utility model relates to the technical field of aviation composite material processing equipment, in particular to a composite material forming die fixing mechanism. Background Art

[0002] Compared with traditional aluminum, steel and titanium materials, the main advantages of aviation composite materials are reduced weight and simpler assembly. Existing aviation composite molding molds are divided into upper molds and lower molds. Previous fixing equipment cannot quickly fix the upper and lower molds of the mold separately, and the efficiency is low.

[0003] In order to solve the above technical problems, a Chinese utility model patent with the authorization announcement number CN212046068U discloses a device for fixing an aviation composite material forming mold. The solution fixes the upper mold and the lower mold of the mold separately by setting a fixing mechanism. The placement groove on the lower fixing plate is used to place the lower mold of the aviation composite material forming mold, and the placement groove on the upper fixing plate is used to place the upper mold of the aviation composite material forming mold. The electric cylinder can drive the upper fixing plate together with the upper mold to move downward to the lower fixing plate for mold closing. However, this solution still has shortcomings: because the fixing plate has a placement groove, the mold lacks support during the process of placing the mold into the placement groove, so one worker is required to cooperate with the support, and another worker operates the fixing mechanism to fix the mold. Therefore, in order to achieve installation, at least two workers are required to cooperate with each other, and the operation is cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0042] See also Figure 1-4 The utility model provides a technical solution: a composite material forming mold fixing mechanism, comprising: a bottom plate 1 and two fixing frames 11 arranged on the bottom plate 1 for placing an upper mold and a lower mold; a fixing component for clamping the mold, the fixing component is arranged in a through slot 28 opened in the fixing frame 11; a driving component for closing or separating the two fixing frames 11; a supporting plate 21 for supporting the bottom of the mold, the supporting plate 21 is slidably arranged at the bottom end of the fixing frame 11; a control component for driving the supporting plate 21 to slide relative to the fixing frame 11, thereby opening or closing the through slot 28;

[0043] The above technical solution can be used to conveniently place the mold into the through slot 28 of the fixing frame 11 and fix it. Since a support plate 21 is provided at the bottom of the through slot 28, after the upper mold is placed into the through slot 28, the bottom end of the upper mold fits with the upper end of the support plate 21, and the support plate 21 supports the upper mold. The upper mold can then be fixed by a fixing assembly, and then the support plate 21 can be removed from the bottom of the through slot 28 by a control assembly. Since the fixing frame 11 of the lower mold is provided at the upper end of the bottom plate 1, the bottom plate 1 can support the lower mold, and therefore there is no need to provide a support plate 21. When the mold needs to be closed, the upper fixing frame 11 can be driven downward by a driving assembly until the two fixing frames 11 are merged to complete the mold closing.

[0044] like Figure 1As shown, in this embodiment, the driving assembly includes: a bracket 2 with a first slide groove 5, the bracket 2 is arranged at the upper end of the bottom plate 1; a first slider 6 connected to the fixing frame 11, the first slider 6 is slidably arranged in the first slide groove 5; a first screw rod 4 rotatably arranged in the first slide groove 5, the first screw rod 4 is matched with a first screw rod groove 7 opened on the surface of the first slider 6; a first motor 3 is arranged at the top end of the bracket 2, and the output shaft of the first motor 3 is connected to the first screw rod 4;

[0045] The above technical solution can drive the fixed frames 11 to move closer to each other, so as to realize the upper and lower mold closing. When working, the first motor 3 is started, the first motor 3 drives the first screw rod 4 to rotate, the first screw rod 4 drives the first slide block 6 to slide downward along the first slide groove 5, and the first slide block 6 drives the fixed frame 11 connected thereto to move downward synchronously until the upper and lower fixed frames 11 are closed, and the mold closing is completed.

[0046] like Figure 3 As shown, in this embodiment, the fixing assembly includes: two clamping blocks 16 relatively arranged in the through slot 28, and a transmission assembly for driving the two clamping blocks 16 to merge or separate with each other; specifically, the transmission assembly includes: a second slider 17 connected to the clamping block 16, the second slider 17 slidingly cooperates with a second slide slot 15 provided in the fixing frame 11; a second screw rod 14 rotatably arranged in the second slide slot 15, the second screw rod 14 cooperates with a second screw rod groove 18 provided on the surface of the second slider 17; a second motor 13 provided at one end of the fixing frame 11, the output shaft of the second motor 13 is connected to the second screw rod 14;

[0047] By adopting the above technical solution, the upper and lower molds can be installed in the fixed frame 11. After the mold is placed in the through slot 28 of the fixed frame 11, the second motor 13 is started to drive the second screw rod 14 to rotate. The second screw rod 14 is a bidirectional screw rod, so that it can drive the two second sliders 17 to slide toward each other along the second slide groove 15, thereby driving the clamping block 16 connected to the second slider 17 to approach each other to clamp the mold.

[0048] Further, such as Figure 3 As shown, in this embodiment, the clamping block 16 is provided with a positioning pin 19 on the side thereof that fits with the mold, and the positioning pin 19 matches with the positioning groove provided on the surface of the mold;

[0049] The adoption of the above technical solution can further improve the clamping stability of the clamp block 16 on the mold and prevent the mold from moving. Since the positioning pin 19 is provided, when the clamp block 16 clamps the mold, the positioning pin 19 will be inserted into the positioning groove on the side of the mold, thereby forming a locking effect and effectively preventing the mold from falling off the fixing frame 11.

[0050] like Figure 4As shown, in this embodiment, a guide protrusion 20 is provided at the bottom end of the fixing frame 11, and the guide protrusion 20 is slidably matched with a guide groove 22 provided on the side of the support plate 21; the control component includes: a third motor 23 connected to the fixing frame 11; a connecting shaft 24 connected to the output shaft of the third motor 23; a gear 25 connected to the connecting shaft 24; a rack 27 matched with the gear 25, and the rack 27 is connected to the support plate 21;

[0051] The above technical solution can control the movement of the support plate 21. When the support plate 21 needs to be moved, the third motor 23 is started, and the third motor 23 drives the connecting shaft 24 and the gear 25 to rotate. The gear 25 engages the rack 27, thereby driving the support plate 21 to slide straight along the guide protrusion 20.

[0052] Further, such as Figure 4 As shown, the rack 27 is disposed in a recessed groove 26 formed on the surface of the support plate 21, and the height of the rack 27 does not exceed the depth of the recessed groove 26;

[0053] The above technical solution can avoid friction between the rack 27 and the bottom end of the upper mold, thereby reducing wear.

[0054] like Figure 3 As shown, in this embodiment, the fixing frame 11 and the first slider 6 are detachably connected; specifically, the mold fixing mechanism further includes: a clamping block 12 provided at one end of the fixing frame 11, the clamping block 12 cooperates with the clamping groove 8 provided in the first slider 6, and a threaded groove 9 is provided at the corresponding position of the clamping block 12 and the first slider 6; a threaded rod 10 with one end rotating in the threaded groove 9 of the first slider 6, and the other end of the threaded rod 10 is screwed into the threaded groove 9 of the clamping block 12;

[0055] The above technical solution can facilitate the disassembly and replacement of the fixing frame 11. When replacement is required, the threaded rod 10 is rotated to disconnect the threaded rod 10 from the threaded groove 9 on the surface of the block 12, and the block 12 is pulled out of the groove 8, and then the fixing frame 11 connected to the block 12 is removed from the first slider 6. In this embodiment, the fixing frame 11 at the lower end is fixed, and its detachable structure is the same as the detachable structure of the fixing frame 11 at the upper end.

[0056] Working principle: When in use, the upper mold and the lower mold are placed in the through groove 28 of the corresponding fixing frame 11, the bottom end of the upper mold is fitted with the upper end of the support plate 21, and the support plate 21 supports the upper mold. Then the second motor 13 is started to drive the second screw rod 14 to rotate. The second screw rod 14 is a bidirectional screw rod, so that it can drive the two second sliders 17 to slide toward each other along the second slide groove 15, thereby driving the clamping block 16 connected to the second slider 17 to approach each other to clamp the mold. Since a positioning pin 19 is provided, when the clamping block 16 clamps the mold, the positioning pin 19 will be inserted into the positioning pin on the side of the mold. The mold is positioned in the groove, thereby forming a locking effect, which effectively prevents the mold from falling off the fixing frame 11, and then the support plate 21 is moved away from the bottom of the through groove 28 through the control component. Since the fixing frame 11 of the lower mold is set at the upper end of the bottom plate 1, the bottom plate 1 can support the lower mold, so there is no need to set the support plate 21. When the mold needs to be closed, the first motor 3 is started, the first motor 3 drives the first screw rod 4 to rotate, the first screw rod 4 drives the first slide block 6 to slide downward along the first slide groove 5, and the first slide block 6 drives the fixing frame 11 connected thereto to move downward synchronously until the upper and lower fixing frames 11 are closed, and the mold is closed.
