[0023] according to Figure 1 、 2 As shown in Figures 3 and 4, a splicable door foaming fixture is proposed in this embodiment, including a lower splint 10, an upper pressing plate 9 is provided above the lower splint 10, a hydraulic lifting plate 8 is provided above the upper pressing plate 9 for pushing the upper pressing plate 9 to fall, a guide device for limiting the upper pressing plate 9 is provided between the lower splint 10 and the upper pressing plate 9, and an elastic member for supporting the upper pressing plate 9 to reset is provided at the bottom of the guide device;

[0024] A discharge frame 1 is provided on one side of the lower clamping plate 10, and a plurality of discharge rollers 3 are rotatably provided inside the discharge frame 1. A loading rack 4 is provided on the other side of the lower clamping plate 10, and a plurality of loading rollers 6 are rotatably provided inside the loading rack 4.

[0025] The inner mold is pushed between the upper platen 9 and the lower clamping plate 10 by the loading roller 6 on the loading frame 4. The hydraulic lifting plate 8 on top of the upper platen 9 is connected to the hydraulic rod. The hydraulic lifting plate 8 pushes the upper platen 9 down to squeeze the inner mold. The guide device limits the upper platen 9. After the hydraulic lifting plate 8 is raised, the elastic member pushes the upper platen 9 back into place. After the mold is closed, the inner mold is sent out through the discharge roller 3 at the top of the discharge frame 1.

[0026] Two limiting rollers 7 are provided between two adjacent feeding rollers 6, and two adjusting plates 17 are provided at the lower end of the feeding frame 4. The two adjusting plates 17 are respectively rotatably connected to the upper ends of the two limiting rollers 7, and the lower end of the feeding frame 4 is provided with an adjusting mechanism for adjusting the distance between the two adjusting plates 17.

[0027] During pushing, the adjustment mechanism adjusts the distance between the two adjustment plates 17, and the limiting roller 7 at the upper end of the adjustment plate 17 limits the inner mold from both sides of the inner mold, while ensuring that the inner mold is pushed to the center of the loading rack 4 and the lower clamping plate 10 without affecting the movement of the inner mold on the loading roller 6, thereby improving the stability of the mold closing.

[0028] In order to improve the support stability of the unloading frame 1, four groups of first pillars 2 are provided at the lower end of the unloading frame 1. The four groups of first pillars 2 are respectively fixedly connected to the four corners of the unloading frame 1. The first pillars 2 support the unloading frame 1 from the bottom.

[0029] In order to improve the support stability of the loading rack 4, four groups of second pillars 5 are provided at the lower end of the loading rack 4, and the four groups of second pillars 5 are respectively fixedly connected to the four corners of the loading rack 4. The second pillars 5 support the loading rack 4 from the bottom of the loading rack 4.

[0030] To improve the mold clamping stability of the lower clamping plate 10, four sets of limit blocks 11 are provided at the lower end of the lower clamping plate 10. The four sets of limit blocks 11 are fixedly connected to the four corners of the lower clamping plate 10. The lower ends of the limit blocks 11 are fixedly connected to the third pillars 12. A support frame 16 is provided between two adjacent third pillars 12. The support frame 16 is fixedly connected to the lower end of the lower clamping plate 10 and is fixedly connected to the third pillars 12. The third pillars 12 support the lower clamping plate 10 from the bottom. The support frame 16 reinforces the third pillars 12 and the unloading frame 1 between the two third pillars 12, thereby improving the impact resistance of the third pillars 12.

[0031] About the guide device:

[0032] The guide device includes four sets of guide posts 13, which are fixedly connected to the four corners of the upper platen 9. The lower ends of the guide posts 13 pass through the limit blocks 11, and the limit blocks 11 are slidably connected to the guide posts 13. When the upper platen 9 moves up and down, the guide posts 13 fixed to the upper platen 9 will also move with it. The limit blocks 11 cooperate with the guide posts 13 to limit the upper platen 9 from the edges of the upper platen 9.

[0033] Specifically, the elastic member includes a limiting cylinder 14 provided below the limiting block 11. The limiting cylinder 14 is sleeved on the outside of the guide column 13. The guide column 13 is slidably connected to the limiting cylinder 14. The third pillar 12 is fixedly connected to the limiting cylinder 14. The upper end of the limiting cylinder 14 is fixedly connected to a spring 15. The upper end of the spring 15 is fixedly connected to the guide column 13. The spring 15 sleeves on the outside of the guide column 13. After the upper pressure plate 9 falls, the guide column 13 falls along with the upper pressure plate 9. The spring between the limiting block 11 and the limiting cylinder 14 contracts. When the thrust applied to the handle 19 disappears, the spring 15 pushes the guide column 13 upward to reset the upper pressure plate 9.

[0034] Regarding the regulating device;

[0035] The adjusting mechanism includes a limiting rod 18 and a double-headed screw 20. The limiting rod 18 is rotatably connected between the front and rear two groups of second pillars 5. The double-headed screw 20 is rotatably connected between the other two groups of second pillars 5. The limiting rod 18 passes through the two adjustment plates 17. The adjustment plates 17 are slidingly connected to the limiting rod 18. The double-headed screw 20 passes through the two adjustment plates 17. The double-headed screw 20 is threadedly connected to the adjustment plate 17. A handle 19 for controlling the rotation of the double-headed screw 20 is provided on the outside of the loading rack 4. The handle 19 is fixedly connected to the double-headed screw 20.

[0036] The outer side of the double-headed screw 20 is provided with two threads, both in positive and negative directions, which respectively cooperate with the two adjustment plates 17. When the handle 19 is turned to control the rotation of the double-headed screw 20, the double-headed screw 20 will cooperate with the two adjustment plates 17, driving the adjustment plates 17 to move along the rod of the double-headed screw 20. The limit rod 18 guides the adjustment plate 17 from the other end of the adjustment plate 17. Due to the different rotation directions of the threads on the outer side of the double-headed screw 20, the two adjustment plates 17 will move in opposite directions when moving, synchronously adjusting the spacing between the limit rollers 7 between the two feeding rollers 6.

[0037] How this application works:

[0038] The inner mold is pushed between the upper pressure plate 9 and the lower clamping plate 10 by the loading roller 6 on the loading frame 4. The hydraulic lifting plate 8 on the top of the upper pressure plate 9 is connected to the hydraulic rod. The hydraulic lifting plate 8 pushes the upper pressure plate 9 down to squeeze the inner mold. The guide device limits the upper pressure plate 9, and after the hydraulic lifting plate 8 is lifted, the elastic member pushes the upper pressure plate 9 back to its position. After the mold is closed, the inner mold is sent out through the unloading roller 3 at the upper end of the unloading frame 1. During pushing, the adjustment mechanism adjusts the distance between the two adjustment plates 17, and the limiting roller 7 at the upper end of the adjustment plate 17 limits the inner mold from both sides of the inner mold. While not affecting the movement of the inner mold on the loading roller 6, it ensures that the inner mold is pushed to the center of the loading frame 4 and the lower clamping plate 10, thereby improving the stability of the mold closing.
