Description

Technical Field

[0001] This utility model relates to the field of seat tray processing, and in particular to a seat tray pressing mold. Background Technology

[0002] The tray is located at the bottom of the seat, connecting the seat cushion, backrest, armrests and other components to the ground. It bears the overall weight of the seat, the load on the human body and the adjustment function. At the same time, it must meet multiple requirements such as stability, comfort, durability and safety. Its design directly affects the ergonomic performance of the seat and is the basis for realizing the seat height adjustment, rotation and tilt functions.

[0003] Currently, seat trays offer the function of adjusting the seat's forward and backward movement and its up and down position. To enhance the functionality of the seat tray, a mechanism for adjusting the seat's left and right sway is installed on it. However, to ensure the left and right sway mechanism can return to its original position, multiple springs need to be installed on the seat tray first, such as... Figure 3 As shown, first place the four springs into the four slots on the seat tray, then place the left and right swing mechanism on the four springs. Press down on the left and right swing mechanism to compress the springs. When the pin holes on the left and right swing mechanism correspond to the pin holes on the seat tray, use the pin to lock the left and right swing mechanism (e.g., Figure 4 As shown in the figure, and because the spring has a large elastic coefficient, it is necessary to invent a seat tray pressing mold to meet the above requirements in order to facilitate pressing the left and right swinging mechanism onto the spring.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4 The seat tray pressing mold shown includes a workbench 1. Two vertical plates 2 are fixedly connected to the top of the workbench 1. A horizontal plate 3 is fixedly connected to the top of both vertical plates 2. A cylinder 4 is fixedly mounted on the top of the horizontal plate 3. The cylinder 4 is connected to an air pump via an external pipe, and the air pump provides power to the cylinder 4. The output end of the cylinder 4 passes through the horizontal plate 3 and is fixedly connected to a jig 5. The jig 5 also includes a first horizontal section 51 and a second horizontal section 52. The first horizontal section 51 is a pressing section, and the second horizontal section 52 is a limiting section. The first horizontal section 51 pushes the pressing mold 6 downwards, thereby pressing the left-right swinging mechanism into the seat tray. The second horizontal section 52 presses down on the buffer spring 15, causing the limiting rod 14 to slide within the limiting cylinder 12 and the pressing cylinder 13, improving the pressing effect. The stability of the mold 6 during downward movement is ensured by connecting the first horizontal section 51 and the second horizontal section 52 via a longitudinal plate. The first horizontal section 51, the second horizontal section 52, and the longitudinal plate are integrally formed. The bottom of the first horizontal section 51 is fixedly connected to the pressing mold 6. A semi-circular pin groove 7 is provided at the center of the bottom of the pressing mold 6. Through the semi-circular pin groove 7, when the left and right swing mechanism is pressed onto the seat tray, the upper half of the pin holes on the seat tray and the left and right swing mechanism are located in the semi-circular pin groove 7. The pin is inserted into the pin holes on the seat tray and the left and right swing mechanism to limit the left and right swing mechanism. Two placement racks 8 for placing seat trays are fixedly installed on the top of the workbench 1. The shape of the placement racks 8 is produced according to the shape of the seat tray and is specifically designed for placing seat trays. Figure 2 As shown, the seat tray is placed on the placement rack 8. The placement rack 8 improves the stability of the seat tray when it is placed and pressed into the left-right swing mechanism. Both the seat tray and the left-right swing mechanism are existing technologies, so their specific structures will not be described in detail. Their specific shapes are as follows: Figure 2 and Figure 3 As shown.

[0020] Support legs 9 are fixedly connected to the four corners of the bottom of the workbench 1, and reinforcing rods 10 are fixedly connected between two adjacent support legs 9 to improve the stability of the seat tray pressing into the left and right swinging mechanism.

[0021] Two abutment posts 11 are provided at the bottom of the first horizontal part 51. The bottom ends of the two abutment posts 11 are fixedly connected to the top of the worktable 1. By providing the abutment posts 11, when the cylinder 4 pushes the die frame 5 to move down, the first horizontal part 51 of the die frame 5 will come into contact with the abutment posts 11, thereby controlling the stroke of the cylinder 4 and preventing the pressing mold 6 from moving down further.

[0022] Two through holes are formed on the surface of the second horizontal section 52, and a limiting cylinder 12 is fixedly connected inside the through holes. A pressing cylinder 13 is fixedly connected to the bottom of the limiting cylinder 12. A limiting rod 14 is provided inside the limiting cylinder 12 and the pressing cylinder 13. A buffer spring 15 is provided on the outer wall of the limiting rod 14. The top of the buffer spring 15 abuts against the bottom of the pressing cylinder 13, and the bottom of the buffer spring 15 abuts against the top of the worktable 1. The buffer spring 15 is compressed when the I-frame 5 moves down and recovers when the I-frame 5 moves up. Since the I-frame 5 is connected to the cylinder 4, vibration will not occur randomly when the elastic force of the buffer spring 15 is less than the force of the cylinder 4. The bottom of the limiting rod 14 is fixedly connected to the top of the worktable 1. By providing a buffer spring 15 at the bottom of the second horizontal section 52, when the cylinder 4 pushes the entire I-frame 5 down, the buffer spring 15 can buffer the downward pressure of the pressing mold 6. And the limiting rod 14 can limit the pressing mold 6.

[0023] The working principle of this utility model is as follows: First, the seat tray that needs to be pressed into the left and right swinging mechanism is placed on the placement rack 8 of the worktable 1. Then, the spring that needs to be pressed into is placed in the slot on the seat tray (e.g., Figure 3 (As shown), the left and right swing mechanism is then placed on four springs. The cylinder 4 pushes the I-frame 5 downwards, and the first horizontal part 51 on the I-frame 5 pushes the pressing mold 6 downwards. The pressing mold 6 then presses the left and right swing mechanism into the seat tray. At this point, the pin holes on the seat tray and the left and right swing mechanism correspond. The pin is inserted into the pin hole to lock the left and right swing mechanism, thus completing the pressing of the left and right swing mechanism (as shown). Figure 4 (As shown).

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
