Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a display back panel forming mold with a guiding mechanism. Background Art

[0002] The display backplane is the supporting structure on the back of the display, usually made of metal or plastic, and provides a mounting base for the internal components of the display (such as circuit boards, power modules). The metal backplane helps to dissipate the heat generated by the internal components and protect the internal components from physical damage or electromagnetic interference. Pressure is applied to the metal sheet through the mold to form the desired shape, which is suitable for mass production.

[0003] The display back panel is placed on the mold, and the mold includes a male mold and a female mold. The male mold and the female mold are docked to realize the stamping and forming of the display back panel. During the stamping and forming process of the display back panel, manual loading and taking of materials are required, and after the display panel is stamped and formed by the mold, it will be placed on the mold. It does not have a structure for automatically guiding the unloading of materials, which increases the cumbersomeness of the mold forming and thus reduces the processing efficiency.

The material plate slides inside the slide groove through the nut to obtain a longitudinal sliding guide, and through the threaded cooperation between the screw and the nut, the nut drives the material plate to move longitudinally, and the limit block prevents the nut from completely separating from the screw.

[0012] Preferably, support plates are provided inside the front and rear sides of the processing box, and equally spaced guide rollers are rotatably mounted on the lower end of the support plates, and a guide plate is provided on the upper end of the bottom plate. The plate for display backplane processing entering the processing box is guided and limited by the guide rollers, and the display backplane discharged from the processing box is received and transported by the guide plate.

[0013] Preferably, the inner walls on both the front and rear sides of the processing box are provided with guide rails and guide sleeves slidably mounted inside the support plate, the upper end of the support plate is provided with a second spring connected to the guide sleeve, and the upper end of the support plate is provided with a guide rod located inside the second spring and slidably plugged into the guide sleeve. The support plate is supported by longitudinal sliding through the guide rails, so that the longitudinal force acting on the plate processed by the display back plate is applied to the support plate through the friction between the plate processed by the display back plate and the support roller, and moves longitudinally synchronously with the plate processed by the display back plate, providing a guide for the plate processed by the display back plate, and the longitudinally moving support plate is automatically reset by the second spring after the force is stopped, and at the same time, when the second spring is longitudinally extended and retracted, the guide rod slides inside the guide sleeve to limit the second spring to prevent the second spring from deflecting.

[0014] Preferably, the steps of using the display back panel forming mold are as follows:

[0015] S1: The plate processed by the display back panel is pre-stored inside the material box. The plate processed by the display back panel is matched with the inner wall of the material box through the support of the plate. The deviation of the plate processed by the display back panel is avoided when lifting. Because the plate is guided, when the motor drives the screw to rotate, the screw pushes the nut to rotate. Through the cooperation of the outer wall of the screw and the inner wall thread of the nut, the plate is driven to be lifted, so that the plate processed by the display back panel at the uppermost end of the plate corresponds to the stroke groove 1, the stroke groove 2, the stroke groove 3 and the stroke groove 4. It is worth mentioning that the length of the telescopic end of the hydraulic rod 2 needs to reach the length that simultaneously passes through the stroke groove 1, the stroke groove 2, the stroke groove 3 and the stroke groove 4, so that the push plate can effectively push the plate processed by the display back panel;

[0016] S2: After the plate processed by the display back panel is pushed into the processing box, it is guided by the guide rail, and the bottom is rolled and supported by the ball bearings, so that the plate processed by the display back panel is guided so that the plate processed by the display back panel is located on the die. When the hydraulic rod 1 drives the telescopic end to descend, driving the punch to descend and fit the plate processed by the display back panel, the plate processed by the display back panel will first apply an extrusion force to the ball bearings, and the extrusion force acts on the spring 3 through the ball bearings. The spring 3 is forced to contract and drives the ball bearings to enter the support tube. The subsequent extrusion force acts on the support tube, exerts an extrusion force on the spring 4, drives the support tube to descend, and descends through the stroke hole inside the die, so that the plate processed by the display back panel is fitted on the die. The extrusion of the punch on the die realizes the pressurized forming of the plate processed by the display back panel;

[0017] S3: When the telescopic end of the hydraulic rod descends and drives the connecting rod to descend, the piston is driven to slide longitudinally in the installation tube. When the piston descends, a suction force is generated in the space above the piston. The suction force acts on the inside of the installation box through the connecting pipe and acts on the inside of the support tube. The support tube is fitted with the plate material processed by the display back panel through a sealing gasket. In the process of the plate material processed by the display back panel being squeezed and lowered, it is guided and positioned by the negative pressure suction force. After the display back panel is processed and formed, the elastic force of spring four acts on the installation box, so that the installation box drives the support rod to lift. After the display back panel is formed, it is separated from the die, and the piston is reset, gradually reducing the suction force inside the support tube. During the lifting process, the negative pressure adsorption force of the display back panel gradually decreases, and is pushed through the stroke slot four to unload the material through the push plate. In the process of the display back panel being formed by the mold, automatic loading, guiding positioning, stamping, demolding and unloading are realized.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The display back panel plate of the present invention is placed on the convex die, and an extrusion force is applied to the display back panel plate through the concave die. The display back panel plate is stamped and formed by the extrusion force. During the forming process of the display back panel plate, the display back panel plate is pushed and loaded by a push plate, and then supported by an elastic support tube. Under the action of the linkage structure, the support tube descends and applies an adsorption force to the lower end of the display back panel plate, so that the display back panel plate is guided and adsorbed and positioned during stamping. The display back panel after stamping is lifted up and separated from the convex die by the elastic part, and the material is automatically unloaded by the push plate. Accurate positioning is achieved by the support tube and the adsorption force, which reduces manual operation and tediousness, simplifies the operation process, and automatically demolds through the elastic part to avoid mold jamming problems, thereby reducing labor costs and improving production efficiency.

This structure not only improves the molding accuracy, but also avoids the problem of scrap rate caused by inaccurate positioning in traditional molds;

[0050] Through the cooperation of the push plate 16 and the hydraulic rod 11, the automatic pushing of the plate and the automatic unloading after forming are realized, which reduces manual operation and improves production efficiency. The support tube 20, the guide roller 28 and the elastically supported ball 37 structure ensure the precise positioning of the plate during the stamping process, avoids deviation and dislocation, and improves the forming accuracy. Through the elastic support of the spring 47 and the support tube 20, the back plate automatically separates from the die 7 after forming, avoiding the problem of die jamming and reducing downtime. The negative pressure adsorption force formed by the piston 23 and the mounting cylinder 2 ensures that the plate is stably fitted to the die 7 during the stamping process, thereby improving the forming quality.

In traditional molds, the back plate after molding is easy to get stuck on the die 7 and needs to be manually cleaned. After improvement, elastic support and automatic demoulding structure are used to avoid mold jamming problems. In traditional molds, plate positioning relies on manual operation and is prone to deviation. After improvement, precise guidance and positioning are achieved through support tube 20 and ball 37 structure. Traditional molds have low production efficiency due to manual operation and mold jamming problems. After improvement, automated design and linkage structure are used to significantly improve production efficiency.

At the same time, it solves the problems of cumbersome manual operation, inaccurate positioning, mold jamming and severe mold wear in traditional molds, and has high practicality and economic value.

[0059] Embodiment three:

[0060] The steps for using the display back panel molding mold are as follows:

[0061] S1: The plate processed on the display back panel is pre-stored inside the material box 3 and supported by the material plate 19. The plate processed on the display back panel is adapted to the inner wall of the material box 3, and the plate processed on the display back panel is avoided from being offset when lifted, because the material plate 19 is guided. When the motor 5 drives the screw 4 to rotate, the screw 4 pushes the nut 15 to rotate, and the outer wall of the screw 4 cooperates with the inner wall thread of the nut 15 to drive the material plate 19 to be lifted, so that the plate processed on the display back panel at the uppermost end of the material plate 19 corresponds to the stroke groove 17, the stroke groove 2 18, the stroke groove 3 44 and the stroke groove 4 45. It is worth noting that the length of the telescopic end of the hydraulic rod 2 11 needs to reach the length that simultaneously passes through the stroke groove 1 17, the stroke groove 2 18, the stroke groove 3 44 and the stroke groove 4 45, so that the push plate 16 can effectively push the plate processed on the display back panel;

[0062] S2: After the plate processed by the display back panel is pushed into the processing box 6, it is guided by the guide rail 27, and the bottom is rolled and supported by the ball 37, so that the plate processed by the display back panel is guided so that the plate processed by the display back panel is located on the die 7. When the hydraulic rod 1 drives the telescopic end to descend, driving the punch 12 to descend and fit the plate processed by the display back panel, the plate processed by the display back panel will first apply an extrusion force to the ball 37, and the extrusion force acts on the spring three 35 through the ball 37. The spring three 35 is forced to shrink and drives the ball 37 to enter the support tube 20. The subsequent extrusion force acts on the support tube 20, exerts an extrusion force on the spring four 47, drives the support tube 20 to descend, and descends through the stroke hole 43 inside the die 7, so that the plate processed by the display back panel is fitted on the die 7, and the extrusion of the die 7 by the punch 12 realizes the pressurized forming of the plate processed by the display back panel;

[0063] S3: When the telescopic end of the hydraulic rod 1 descends and drives the connecting rod 22 to descend, the piston 23 is driven to slide longitudinally in the installation tube 2. When the piston 23 descends, a suction force is generated in the space above the piston 23. The suction force acts on the inside of the installation box 21 through the connecting tube 24 and acts on the inside of the support tube 20. The support tube 20 is fitted with the plate material processed by the display back panel through the sealing gasket 38. In the process of the plate material processed by the display back panel being squeezed and lowered, it is guided and positioned by the negative pressure suction force. After the display back panel is processed and formed, the elastic force of the spring four 47 acts on the installation box 21, so that the installation box 21 drives the support rod to lift. After the display back panel is formed, it is separated from the concave mold 7, and the piston 23 is reset, gradually reducing the suction force inside the support tube 20. The negative pressure adsorption force of the display back panel during the lifting process gradually decreases, and is pushed through the stroke groove four 45 by the push plate 16 to unload the material. In the process of the display back panel being formed by the mold, automatic loading, guiding positioning, stamping, demolding and unloading are realized.

10. The display back panel forming mold with a guiding mechanism according to claim 1, characterized in that: The steps for using the display back panel molding mold are as follows: S1: The plate material for display back panel processing is pre-stored inside the material box (3) and supported by the material plate (19). The plate material for display back panel processing is adapted to the inner wall of the material box (3), and the plate material for display back panel processing is prevented from being offset when being lifted. Because the plate material (19) is guided, when the motor (5) drives the screw rod (4) to rotate, the screw rod (4) pushes the nut (15) to rotate, and the plate material (19) is lifted by the cooperation of the outer wall of the screw rod (4) and the inner wall thread of the nut (15), so that the plate material for display back panel processing at the uppermost end of the plate material (19) corresponds to the stroke groove 1 (17), the stroke groove 2 (18), the stroke groove 3 (44) and the stroke groove 4 (45). It is worth noting that the length of the telescopic end of the hydraulic rod 2 (11) needs to reach the length that simultaneously passes through the stroke groove 1 (17), the stroke groove 2 (18), the stroke groove 3 (44) and the stroke groove 4 (45), so that the push plate (16) can effectively push the plate material for display back panel processing; S2: After the plate to be processed on the display back panel is pushed into the processing box (6), it is guided by the guide rail (27) and the bottom is supported by the ball bearing (37) to guide the plate to be processed on the display back panel so that the plate to be processed on the display back panel is located on the concave die (7). When the hydraulic rod (1) drives the telescopic end to descend and drives the convex die (12) to descend and fit the plate to be processed on the display back panel, the plate to be processed on the display back panel will first apply an extrusion force to the ball bearing (37), and the extrusion force is applied to the ball bearing (37) through the ball bearing (37). The ball (37) acts on the spring three (35), and the spring three (35) contracts under force, driving the ball (37) to enter the support tube (20). The subsequent extrusion force acts on the support tube (20), exerts an extrusion force on the spring four (47), drives the support tube (20) to descend, and descends through the stroke hole (43) inside the concave die (7), so that the plate material processed by the display back plate fits on the concave die (7), and the convex die (12) squeezes the concave die (7) to achieve pressure molding of the plate material processed by the display back plate; S3: When the telescopic end of the hydraulic rod (1) descends and drives the connecting rod (22) to descend, the piston (23) is driven to slide longitudinally in the installation cylinder (2). When the piston (23) descends, a suction force is generated in the space above the piston (23). The suction force acts on the inside of the installation box (21) through the connecting pipe (24) and acts on the inside of the support pipe (20). The support pipe (20) is fitted with the plate processed on the display back plate through the sealing gasket (38). When the plate processed on the display back plate is squeezed and descended, it is guided and positioned by the negative pressure suction force. After the display back panel is processed and formed, the elastic force of the spring four (47) acts on the installation box (21), so that the installation box (21) drives the support rod to lift. After the display back panel is formed, it is separated from the concave mold (7), and the piston (23) is reset, gradually reducing the suction force inside the support tube (20). During the lifting process, the negative pressure adsorption force of the display back panel gradually decreases, and the push plate (16) pushes it through the stroke groove four (45) to discharge the material. In the process of the display back panel being formed by the mold, automatic loading, guiding positioning, stamping, demoulding and unloading are realized.
