[0002] A watch is one of the most common accessories for displaying time in people's daily life. With the development of technology, a watch can not only be used as an ornament, but also become a smart watch after being equipped with built-in intelligent monitoring components. Now, people in China pay more attention to health. After being connected to a mobile phone, a smart watch can monitor the health of the wearer, such as heart rate and blood oxygen, and assist the wearer in obtaining daily physical index data, meeting the needs of people in China for a healthy life. At the same time, a smart watch can also be used as a life tool, enabling the smart watch to have functions such as querying the weather, calendar, temperature, and geographical location. Therefore, a smart watch can replace a traditional watch in daily life. A smart watch generally includes a case, a smart watch core, and a watch band. When processing the case, a corresponding processing die is often required for clamping and positioning. After determining the thickness of the watch case to be processed, it is obtained by cutting.

[0003] After the existing processing die for an electronic watch case completes the operation on the case, the product is first ejected by an ejection mechanism, and then the push plate is driven to reciprocate by a feeding mechanism to achieve convenient feeding. However, the following problems will occur during this operation process:

[0004] 1. After the push plate completes pushing the material, it needs to be driven by the feeding mechanism to move to the initial position before the next pushing operation can be carried out, which will cause waste of time and affect the operation efficiency.

[0005] 2. After the die processes the case, some raw materials will remain inside the die, affecting the quality of subsequent case production and thus resulting in a decrease in the product qualification rate. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the utility model is to provide a processing die for an electronic watch case, which can improve the production efficiency and quality of the case.

[0009] Preferably, placing grooves are symmetrically formed on the mutually approaching sides of the two groups of mounting frames, and the two transmission belts are respectively arranged in the two placing grooves and the surfaces are flush with the mounting frames.

[0010] Preferably, the transmission belt includes chain wheels symmetrically arranged at both ends of the placing groove and rotatably connected to the placing groove, and a transmission chain wound around the outer sides of the two chain wheels, and both sides of the chain wheel are respectively rotatably connected to the mounting frame and the lower mold.

[0011] Preferably, the blanking component includes an electric push rod fixed inside the lower mold and a push plate fixed to the top of the electric push rod; a through groove adapted to the push plate is formed on the top of the lower mold, and the push plate is slidably connected to the through groove.

[0012] Preferably, the lifting mechanism includes linear drivers symmetrically arranged on both sides of the blanking mechanism and a mounting plate with both ends respectively fixed to the driving ends of the two linear drivers, and the upper mold is fixed to the bottom of the mounting plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. Through the cooperation of the transmission belt, the blanking plate and the cleaning brush, on the one hand, the time for the blanking plate to return to the initial position after pushing the material can be saved, improving the processing efficiency. On the other hand, the lower mold can be cleaned simultaneously, thus avoiding the influence of part of the raw material residue on the quality of the subsequent product processing and improving the product qualification rate;

[0015] 2. Through the cooperation of the scraper and the cleaning brush, the cleaning of the cleaning brush can be realized, avoiding too much raw material residue on the cleaning brush from affecting the subsequent cleaning. Description of the Drawings

Specific embodiments

[0022] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0023] An electronic watch case processing die includes symmetrically arranged mounting frames 1, a lifting mechanism 2 fixed to the tops of two groups of mounting frames 1, an upper die 3 fixed to the bottom of the lifting mechanism 2, a lower die 4 fixed between two groups of mounting frames 1, a stripping component 5 arranged in the lower die 4 and slidably connected to the lower die 4, and a blank discharging mechanism 6 mounted on the top of the lower die 4; the blank discharging mechanism 6 includes symmetrically arranged transmission belts 61 on both sides of the lower die 4, a plurality of blank discharging plates 62 respectively fixed to the two groups of transmission belts 61 at both ends, and a cleaning brush 63 elastically connected to the bottom of the blank discharging plate 62; one end of the lower die 4 is fixedly connected with a scraper 64, and the scraper 64 cooperates with the cleaning brush 63 to clean the cleaning brush 63.

[0024] Through the cooperation of the transmission belt 61, the blank discharging plate 62 and the cleaning brush 63, on the one hand, it can save the time for the blank discharging plate 62 to return to the initial position after pushing the material, improve the processing efficiency, and on the other hand, it can clean the lower die 4 at the same time, thus avoiding the influence of part of the raw material residue on the quality of the subsequent product processing and improving the product qualification rate; through the cooperation of the scraper 64 and the cleaning brush 63, the cleaning of the cleaning brush 63 can be realized, and the influence of too much raw material residue on the subsequent cleaning on the cleaning brush 63 can be avoided.

[0025] As a possible implementation manner of this solution, preferably, placing grooves 11 are symmetrically opened on the mutually approaching sides of the two groups of mounting frames 1, and the two groups of transmission belts 61 are respectively arranged in the two groups of placing grooves 11 and the surfaces are flush with the mounting frames 1.

[0026] As a possible implementation of this solution, preferably, the conveyor belt 61 includes sprockets 611 symmetrically arranged at both ends of the placement groove 11 and rotatably connected to the placement groove 11, and a conveyor chain 612 wound around the outer sides of the two sprockets 611. The two sides of each sprocket 611 are respectively rotatably connected to the mounting frame 1 and the lower die 4. The sprockets 611 are driven to rotate by a motor, so that the conveyor chain 612 drives the blanking plate 62 and the cleaning brush 63 to rotate, so as to realize the pushing of the product and the cleaning of the lower die 4.

[0027] As a possible implementation of this solution, preferably, the ejector assembly 5 includes an electric push rod 51 fixed inside the lower die 4 and a push plate 52 fixed on the top of the electric push rod 51. A through groove 41 adapted to the push plate 52 is formed at the top of the lower die 4, and the push plate 52 is slidably connected to the through groove 41. By providing the electric push rod 51 and the push plate 52, the product can be separated from the lower die 4 to facilitate the removal of the product.

[0028] As a possible implementation of this solution, preferably, the lifting mechanism 2 includes linear actuators 21 symmetrically arranged on both sides of the blanking mechanism 6 and a mounting plate 22 with both ends fixed to the driving ends of the two linear actuators 21 respectively. The upper die 3 is fixed to the bottom of the mounting plate 22. By the cooperation of the linear actuator 21 and the mounting plate 22, the upper die 3 can be separated from the lower die 4 to facilitate the removal of the product.

[0029] The working principle of this device is as follows:

[0030] When the product is processed, first, the upper die 3 is separated from the lower die 4 through the lifting mechanism 2, and then the product is separated from the lower die 4 through the ejector assembly 5. Then, the motor drives the sprockets 611 to drive the conveyor chain 612 to rotate, so that the blanking plate 62 pushes the product to move. At the same time, since the cleaning brush 63 and the blanking plate 62 are elastically connected by a spring, the lower end of the cleaning brush 63 abuts against the lower die 4 under the action of the spring, so as to realize the cleaning of the lower die 4. When the cleaning brush 63 rotates to one side of the scraper 64, the scraper 64 cleans the cleaning brush 63.

[0031] The above are only the specific implementation manners of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
