Description

Technical Field

[0001] This utility model relates to the field of printer housing production, and in particular to a continuous stamping die for printer housing production. Background Technology

[0002] A printer is a computer output device used to print computer-processed results onto relevant media. Three key indicators of printer quality are print resolution, print speed, and noise level. There are many types of printers. Based on whether the printing element strikes the paper, they are divided into impact printers and non-impact printers. Based on the structure of the printed characters, they are divided into full-character printers and dot-matrix character printers. Based on how a line of text is formed on the paper, they are divided into serial printers and line printers. Based on the technology used, they are divided into column printers, ball printers, inkjet printers, thermal printers, laser printers, electrostatic printers, magnetic printers, and LED printers, etc. The printer casing requires stamping dies for processing during production.

[0003] The related technology includes guide pillars, an upper die base, and a lower die base. Guide pillars are set at the four corners of the upper die base, and the guide pillars pass through the four corners of the upper die base. An upper die is set below the upper die base. A cavity is set in the middle of the lower die base, and a lower die is set in the cavity. The lower die includes a lower die positioning mechanism, a lower core, and a buffer spring. The lower die positioning mechanism has a mold cavity, and a buffer spring is set at the bottom of the mold cavity. The other end of the buffer spring is fixedly connected to the lower core. The upper die and the lower die are connected by bolts, which not only makes the connection stable but also allows for disassembly and easy replacement. By setting a movable lower core, the stamped part is ejected at the same time as the stamping ends, avoiding secondary damage to the stamped part caused by manual removal, while improving stamping efficiency. The structure is simple and highly practical.

[0004] However, after the outer shell is stamped, the tight contact between the outer shell and the lower die results in a strong adhesion between them, and the outer shell is in a relatively fixed state. Thus, the elastic force of the buffer spring alone cannot quickly eject the outer shell, making it difficult to quickly remove and unload the outer shell, thereby reducing the unloading efficiency of the outer shell.

[0005] Therefore, it is necessary to provide a continuous stamping die for the production of printer housings to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a continuous stamping die for the production of printer housings.

[0007] This utility model provides a continuous stamping die for producing printer housings, comprising: a base, a bracket fixed to the top of the base, a hydraulic cylinder fixed to the bottom of the bracket, an upper die body fixed to the telescopic end of the hydraulic cylinder, a lower die body corresponding to the upper die body fixed to the top of the base, a material plate slidably disposed inside the lower die body, pads that abut against the material plate fixed on both sides of the inner wall of the lower die body, a movable impact plate that abuts against the material plate inside the lower die body, a slot opened on one side of the lower die body, a lever rotatably connected in the slot, and a connecting rod hinged to the impact plate at one end of the lever;

[0008] A swing assembly is disposed on one side of the lower mold body. The swing assembly is connected to the lever and is used to drive the lever to swing.

[0009] A support assembly, located between the lower mold body and the impact plate, is used to support the movement of the impact plate.

[0010] Preferably, the swing assembly includes a pull rod hinged to one end of the lever, a first slider hinged to the top of the pull rod, a first groove for the first slider to slide on one side of the lower mold body, and an electric telescopic rod fixed in the first groove and fixed to the first slider.

[0011] Preferably, the support assembly includes a first support rod fixedly disposed at the bottom end of the inner wall of the lower mold, and a second support rod fixed to the impact plate is inserted and connected to the top end of the first support rod.

[0012] Preferably, grooves are provided on both sides of the top of the lower mold body, and buffer plates are inserted and connected in both grooves. Both buffer plates are connected to the grooves through sliding components. Rubber pads that abut against the upper mold body are fixed at the top of both buffer plates, and buffer components connected to the buffer plates are provided in both grooves.

[0013] Preferably, the sliding assembly includes a second slider fixedly disposed on both sides of the buffer plate, and a second groove is provided on both sides of the inner wall of the groove for the second slider to slide.

[0014] Preferably, the buffer assembly includes a buffer rod fixedly disposed at the bottom end of the buffer plate, and a buffer groove is provided at the bottom end of the inner wall of the groove for the buffer rod to pass through. A damper fixed in the buffer groove and the buffer rod is fixed therein, and a buffer spring is sleeved on the outer wall of the damper.

[0015] Compared with related technologies, the continuous stamping die for printer housing production provided by this utility model has the following beneficial effects:

[0016] 1. A continuous stamping die for producing printer housings according to an embodiment of this application uses a hydraulic cylinder to drive the upper die body to move up and down, thereby continuously stamping the housing. After the housing is stamped, the hydraulic cylinder drives the upper die body to move upward and separate from the lower die body. Then, under the movement of the swing component, the lever swings. The lever drives the impact plate to move up and down through the connecting rod. The impact plate hits the material plate during its up and down movement. Under the impact, the housing and the lower die body are loosened, reducing the adhesion between the housing and the lower die body. Then, the material plate is ejected upward by the ejection spring set on the pad, thereby ejecting the housing upward. This facilitates the ejection of the housing, avoids the housing from sticking tightly and making it difficult to eject, and improves the ejection efficiency of the housing.

[0017] 2. A continuous stamping die for producing a printer housing according to an embodiment of this application, when the hydraulic cylinder drives the upper die body to move downward to close the die, before the upper die body contacts the lower die body, the upper die body first contacts the buffer plate and the rubber pad. Then, as the upper die body continues to move downward, it squeezes the buffer plate, and the buffer plate can squeeze the buffer assembly. In this way, with the cooperation of the buffer assembly, the upper die body can be buffered, thereby reducing the collision damage between the upper die body and the lower die body, facilitating the processing of the housing, and improving the processing efficiency of the housing.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 A continuous stamping die for producing printer housings includes: a base 1, a bracket 2 fixed to the top of the base 1, a hydraulic cylinder 3 fixed to the bottom of the bracket 2, an upper die body 4 fixed to the telescopic end of the hydraulic cylinder 3, a lower die body 5 corresponding to the upper die body 4 fixed to the top of the base 1, a material plate 6 slidably provided inside the lower die body 5, pads 7 that abut against the material plate 6 fixed on both sides of the inner wall of the lower die body 5, a movable impact plate 8 that abuts against the material plate 6 provided inside the lower die body 5, a slot 9 opened on one side of the lower die body 5, a lever 10 rotatably connected inside the slot 9, and a connecting rod 11 hinged to the impact plate 8 at one end of the lever 10.

[0025] The swing assembly 12 is disposed on one side of the lower mold body 5. The swing assembly 12 is connected to the lever 10 and is used to drive the lever 10 to swing.

[0026] Support component 13 is disposed between the lower mold body 5 and the impact plate 8 to support the movement of the impact plate 8.

[0027] In this embodiment, the upper mold body 4 is driven to move up and down by the hydraulic cylinder 3, so that the outer shell can be continuously stamped. After the outer shell is stamped, the upper mold body 4 is driven to move upward by the hydraulic cylinder 3 to separate from the lower mold body 5. Then, under the movement of the swing component 12, the lever 10 is driven to swing. The lever 10 can drive the impact plate 8 to move up and down through the connecting rod 11. The impact plate 8 impacts the material plate 6 during its up and down movement. Under the impact, the outer shell and the lower mold body 5 are loosened, reducing the adhesion between the outer shell and the lower mold body 5. Then, the material plate 6 can be ejected upward by the discharge spring set on the pad 7, thereby ejecting the outer shell upward. This facilitates the discharge of the outer shell, avoids the outer shell being tightly adhered and inconvenient to discharge, and improves the discharge efficiency of the outer shell.

[0028] In a further embodiment, such as Figure 2 As shown, the swing assembly 12 includes a pull rod 121 hinged to one end of the lever 10. A first slider 122 is hinged to the top of the pull rod 121. A first groove 123 for sliding the first slider 122 is provided on one side of the lower mold body 5. An electric telescopic rod 124 fixed to the first slider 122 is fixed in the first groove 123.

[0029] In this embodiment, when the outer shell needs to be discharged, the extension and retraction of the electric telescopic rod 124 can drive the first slider 122 to move up and down. The first slider 122 pulls the pull rod 121 to move up and down, and the pull rod 121 can pull the lever 10 to swing up and down. The lever 10 can drive the impact plate 8 to move up and down through the connecting rod 11. The impact plate 8 can impact the material plate 6 during its up and down movement. Under the impact, the material plate 6 can drive the movement of the outer shell, making the outer shell loose between the outer shell and the lower mold body 5, thereby facilitating the discharge of the outer shell.

[0030] In a further embodiment, such as Figure 2 As shown, the support assembly 13 includes a first support rod 131 fixedly disposed at the bottom of the inner wall of the lower mold body 5, and a second support rod 132 fixed to the impact plate 8 is inserted and connected to the top of the first support rod 131.

[0031] In this embodiment, when the lever 10 drives the impact plate 8 to move through the connecting rod 11, the impact plate 8 drives the first support rod 131 and the second support rod 132 to move in an interlacing motion. In this way, the impact plate 8 can be assisted and limited by the interlacing cooperation of the first support rod 131 and the second support rod 132, so as to facilitate the stable up and down movement of the impact plate 8.

[0032] In a further embodiment, such as Figure 3 As shown, grooves 14 are provided on both sides of the top of the lower mold body 5. Buffer plates 15 are inserted into each of the two grooves 14. Both buffer plates 15 are connected to the grooves 14 through sliding components 16. Rubber pads 17 that abut against the upper mold body 4 are fixed to the top of each of the two buffer plates 15. Buffer components 18 connected to the buffer plates 15 are provided in each of the two grooves 14.

[0033] In this embodiment, when the hydraulic cylinder 3 drives the upper mold body 4 to move downward to close the mold, before the upper mold body 4 contacts the lower mold body 5, the upper mold body 4 first contacts the buffer plate 15 and the rubber pad 17. Then, as the upper mold body 4 continues to move downward, it presses the buffer plate 15, which in turn presses the buffer assembly 18. In this way, with the cooperation of the buffer assembly 18, the upper mold body 4 can be buffered, thereby reducing the collision damage between the upper mold body 4 and the lower mold body 5, facilitating the processing of the outer shell, and improving the processing efficiency of the outer shell.

[0034] In a further embodiment, such as Figure 4 As shown, the sliding assembly 16 includes a second slider 161 fixedly disposed on both sides of the buffer plate 15, and a second groove 162 for sliding the second slider 161 is provided on both sides of the inner wall of the groove 14.

[0035] In this embodiment, when the upper mold body 4 presses down on the buffer plate 15, the buffer plate 15 drives the second slider 161 to slide in the second slide groove 162. In this way, with the cooperation of the second slider 161 and the second slide groove 162, the buffer plate 15 can be provided with auxiliary support to maintain the stability of the movement of the buffer plate 15. When the upper mold body 4 and the lower mold body 5 are completely closed, the buffer plate 15 is completely pressed into the groove 14, which can avoid the gap between the upper mold body 4 and the lower mold body 5.

[0036] In a further embodiment, such as Figure 3 As shown, the buffer assembly 18 includes a buffer rod 181 fixedly disposed at the bottom end of the buffer plate 15. A buffer groove 182 is provided at the bottom end of the inner wall of the groove 14 for the buffer rod 181 to pass through. A damper 183 fixed in the buffer groove 182 and fixed to the buffer rod 181 is fixed therein. A buffer spring 184 is sleeved on the outer wall of the damper 183.

[0037] In this embodiment, when the upper mold body 4 presses down on the buffer plate 15, the buffer plate 15 drives the buffer rod 181 to move downward. During the movement of the buffer rod 181, it presses against the damper 183 and the buffer spring 184. In this way, with the cooperation of the damper 183 and the buffer spring 184, the upper mold body 4 can be buffered and protected, reducing the collision damage between the upper mold body 4 and the lower mold body 5.

[0038] The working principle of the continuous stamping die for printer housing production provided by this utility model is as follows: When the hydraulic cylinder 3 drives the upper die body 4 to move downward to close the die, before the upper die body 4 contacts the lower die body 5, the upper die body 4 first contacts the buffer plate 15 and the rubber pad 17. Then, as the upper die body 4 continues to move downward, it presses against the buffer plate 15. The buffer plate 15 drives the buffer rod 181 to move downward. During the movement of the buffer rod 181, it presses against the damper 183 and the buffer spring 184. In this way, with the cooperation of the damper 183 and the buffer spring 184, the upper die body 4 can be buffered and protected, reducing the collision damage between the upper die body 4 and the lower die body 5, facilitating the processing of the housing, and improving the processing efficiency of the housing. Thus, the housing can be stamped. After processing is completed, the hydraulic cylinder... 3. The upper mold body 4 moves upward and separates from the lower mold body 5. Then, under the extension and retraction of the electric telescopic rod 124, the first slider 122 moves up and down. The first slider 122 pulls the pull rod 121 up and down, and the pull rod 121 pulls the lever 10 to swing up and down. The lever 10 can drive the impact plate 8 to move up and down through the connecting rod 11. The impact plate 8 can hit the material plate 6 during its up and down movement. Under the impact, the material plate 6 can drive the outer shell to move, making the outer shell loose from the lower mold body 5 and reducing the adhesion between the outer shell and the lower mold body 5. Then, through the discharge spring set on the pad 7, the material plate 6 can be popped up, thereby popping the outer shell up. This facilitates the discharge of the outer shell, avoids the outer shell sticking tightly and making it inconvenient to discharge, and improves the discharge efficiency of the outer shell.
