After 30 minutes of waiting for the glue to solidify, the rubber band is removed to complete the entire pressure holding process. Although it is very simple, it has great disadvantages, the most prominent of which is that the rubber band will become loose after repeated use, the pressure holding effect will be reduced, and the pressure holding efficiency is low due to the reliance on manual wrapping of the rubber band around the shell to achieve pressure holding. Therefore, the prior art needs to be improved to solve the problem of low pressure holding efficiency and poor pressure holding effect caused by the prior art using manual wrapping of the rubber band around the shell to achieve pressure holding.

[0020] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] The utility model designs a pressure-maintaining fixture, which includes an upper mold, a lower mold and a locking assembly. The lower mold is provided with a first accommodating cavity 6. The workpiece is placed in the first accommodating cavity 6 and fits the first accommodating cavity 6. The locking assembly includes a first locking piece 100 and a second locking piece 10. The first locking piece 100 is connected to the upper mold, and the second locking piece 10 is connected to the lower mold. The upper mold is driven to move to abut the workpiece, and the first locking piece 100 and the second locking piece 10 are movably connected to lock the upper mold and the lower mold.

[0023] It should be noted that the utility model places the workpiece between the upper die and the lower die, and uses the upper die and the lower die to press the workpiece together to achieve pressure holding. Compared with the prior art that achieves pressure holding by wrapping a rubber band around the shell, the pressure holding effect is significantly enhanced. The upper die is driven to move to abut the workpiece, and the first locking piece 100 is connected to the second locking piece 10. The upper die and the lower die are locked, and the workpiece can be pressure-held. Compared with the prior art, the pressure holding efficiency is significantly improved, which solves the problem of low pressure holding efficiency and poor pressure holding effect caused by manually wrapping a rubber band around the shell to achieve pressure holding in the prior art.

[0024] Specifically, the first locking member 100 is provided with a hook 3 , and the second locking member 10 is provided with a limiting shaft 11 . The upper die is driven to move to abut against the workpiece, and the hook 3 is engaged with the limiting shaft 11 .

[0025] Specifically, the first locking member 100 also includes a fixed block 12, a connecting block 13 and a pressing block 14. The fixed block 12 is connected to the upper mold, the connecting block 13 is rotatably connected to the fixed block 12, one end of the connecting block 13 close to the second locking member 10 is connected to the hook 3, and the other end of the connecting block 13 is connected to the pressing block 14.

[0026] When the upper mold of the utility model is driven to move to abut the workpiece, the hook 3 will engage the limit shaft 11. At this time, pressing the pressure block 14 in the direction close to the upper mold can realize the locking of the first locking member 100 and the second locking member 10. After the pressure holding is completed, the pressure block 14 is bent in the direction away from the upper mold to make the hook 3 disengage from the limit shaft 11 to cancel the locking of the first locking member 100 and the second locking member 10. The structure is simple and practical. The locking component of the utility model is the same as the principle of the buckle in the prior art, and the utility model will not elaborate on this. Of course, it should be noted that in actual applications, people can also achieve the locking of the upper mold and the lower mold in other ways, and the utility model does not limit this.

[0027] Specifically, in order to enhance the guiding, the pressure-maintaining fixture of the utility model further includes a guide column, which is connected to the lower die and passes through the upper die, and the upper die is slidably connected to the guide column.

[0028] Specifically, the lower mold includes a first positioning plate 5 , the lower pressing plate 4 is connected to the first positioning plate 5 , the first positioning plate 5 is a flexible member, and a plurality of first accommodating cavities 6 are formed on the first positioning plate 5 .

[0029] Specifically, the upper mold includes an upper pressure plate 1 and a second positioning plate 2. The upper pressure plate 1 is connected to the second positioning plate 2. The second positioning plate 2 is a flexible member. The second positioning plate 2 has a second accommodating cavity at a position corresponding to the first accommodating cavity 6. When the upper mold moves to abut the workpiece, the second accommodating cavity adheres to and abuts the workpiece.

[0030] When the upper die of the utility model abuts against the workpiece, the upper die slides along the guide column, and the first accommodating cavity 6 faces the second accommodating cavity. The size of the first accommodating cavity 6 matches the upper shell of the workpiece, and the size of the second accommodating cavity matches the lower shell of the workpiece. The first accommodating cavity 6 and the second accommodating cavity both fit the workpiece, and all parts of the workpiece can be subjected to pressure, and the pressure maintaining effect is greatly enhanced. The first positioning plate 5 and the second positioning plate 2 are both flexible parts, which avoids the problem of scratches on the workpiece.

[0031] Specifically, the pressure-maintaining fixture further includes an elastic member 9, the lower die includes a lower pressing plate 4 and a limiting platform 7, a second locking member 10 is connected to the limiting platform 7, the limiting platform 7 is provided with a movable groove 8, the lower pressing plate 4 is arranged in the movable groove 8, and the elastic member 9 connects the groove bottom of the movable groove 8 and the lower pressing plate 4. The elastic member 9 of the utility model is a spring, and when the pressing block 14 presses the upper die downward to close the upper die, the elastic member 9 is in a compressed state and provides an elastic force to the lower pressing plate 4 to approach along the direction of the upper die, and the pressure-maintaining effect of the upper die and the lower die on the workpiece is greatly enhanced.

[0032] Specifically, the pressure-maintaining fixture further includes an air pump, and the first accommodating chamber 6 is provided with an opening, and the air pump is connected to the opening. After the pressure-maintaining of the utility model is completed, the air pump is started, and the gas output by the air pump can push the workpiece out of the first accommodating chamber 6 through the opening, so that people can unload the workpiece.

[0033] Specifically, the pressure-maintaining fixture also includes a timer and an indicator light. The timer is used to measure the pressing time of the upper die and the lower die on the workpiece in real time, and the indicator light is electrically connected to the timer.

[0034] When the timer of the utility model reaches the preset pressure holding time, it will send a signal to the indicator light, and the indicator light can be activated to remind people to unload materials in time, avoiding the problem of poor pressure holding effect caused by too long or too short pressure holding time in the prior art. Of course, the utility model does not limit the preset pressure holding time, and people can set it by themselves.
