Abstract
Description

[0002] Foamed products are widely found in daily life. They are made using a foaming process, a common manufacturing technique used to produce foamed plastic products applicable to packaging, construction, automotive, and electronics industries. Specifically, foamed products can be used in automobiles or other vehicles as interior trim or other functional structures. Compression molding is a common polymer foaming process widely used in insulation, structural, and soundproofing materials. This process involves pouring a pre-prepared foamed polymer into the cavity of a mold under high temperature and pressure, allowing it to expand and solidify to form the final product. When producing foamed parts using compression molding, compression molding is required. During operation, powdered, granular, or fibrous plastic is placed into the mold cavity at the molding temperature, and then the mold is closed and pressure is applied to shape and solidify the foam.

[0047] This application provides a foaming injection robot for an open press, which automates the injection process. The foaming injection robot is installed on top of the open press and extends downwards into the interior of the open press to inject material. Therefore, it has a compact structure, minimal impact on the operating space, and no equipment or tracks on the ground operating position, thus solving the problem of large molds and products entering and exiting the mold frame.
[0048] refer to Figure 1 and Figure 2 The foaming injection robot 200 includes at least a guide rail 10, a base 20, a first drive assembly 50, an L-shaped arm 30, and a feeding assembly.

[0051] The feeding assembly includes a foaming machine material tank 91, an injection head 92, a delivery pump 93, and a material conveying pipeline 94; the foaming machine material tank 91 and the injection head 92 are connected by the material conveying pipeline 94; the delivery pump 93 is installed on the material conveying pipeline 94 and is used to drive the foaming material in the foaming machine material tank 91 to be conveyed to the injection head 92; the injection head 92 is located on the horizontal arm 32 of the L-shaped arm 30 and is used to inject the foaming material into the foaming mold.
[0052] Specifically, the guide rail 10 extends along the first horizontal direction x, and the base 20 is limited to move along the guide rail 10, that is, limited to move along the first horizontal direction x. Further, a guide cantilever 21 is provided on the base 20. The L-shaped arm 30 consists of a vertical arm portion 31 and a horizontal arm portion 32. On one hand, the vertical arm portion 31 is supported on the guide cantilever 21 and can be adjusted relative to the guide cantilever 21 in the second horizontal direction y and the vertical direction z.

The guiding cantilever 21 and the L-shaped arm 30 form a "匸"-shaped structure.
[0056] In Figure 1 In the structure shown, the foaming mold includes an upper mold and a lower mold, and the injection head 92 is used to inject foaming material into the lower mold. Specifically, after the upper mold separates upward from the lower mold, the L-shaped arm 30 moves into the open press 100 along the second horizontal direction y, and the horizontal arm portion 32 of the L-shaped arm 30 extends into the injection space R above the lower mold. Before the upper mold and the lower mold are closed, the L-shaped arm 30 moves in the direction of exiting the open press 100 along the second horizontal direction y, and the horizontal arm portion 32 of the L-shaped arm 30 exits the injection space R.
[0057] The vertical arm portion 31 of the L-shaped arm 30 is carried on the guiding cantilever 21 and can be moved and adjusted relative to the guiding cantilever 21 in the second horizontal direction y and the vertical direction z.

[0059] refer to Figure 2 and Figure 3 The first drive assembly 50 includes a first rack 51, a first gear 52, and a first servo motor 53; wherein, the first rack 51 is fixed to the top of the open press and extends along the first horizontal direction x; the first gear 52 is in transmission engagement with the first rack 51; the first servo motor 53 is mounted on the base 20 and is used to connect and drive the first gear 52 to drive the base 20 to move and adjust on the guide rail 10.
[0060] Specifically, the first drive assembly 50 is a gear and rack transmission mechanism. When the first servo motor 53 drives the first gear 52 to rotate, it can drive the base 20 to move and adjust on the guide rail 10. In the first drive assembly 50, the first gear 52 is the driving element, and the first rack 51 is the driven element. When the first gear 52 starts to rotate under the driving force of the first servo motor 53, its tooth surface will mesh with the tooth surface of the first rack 51. As the first gear 52 continues to rotate, it will move along the extension direction of the first rack 51, thereby driving the base 20 to move and adjust on the guide rail 10. In addition, the first servo motor 53 can perform precise displacement adjustment of the base 20.
[0061] refer to Figure 4 The second drive assembly 60 includes a second rack 61, a second gear 62, and a second servo motor 63.

The second servo motor 63 is mounted on the movable frame 40 and is used to connect and drive the second gear 62 to drive the movable frame 40 to move and adjust relative to the guide cantilever 21.
[0062] Specifically, the second drive assembly 60 is a gear and rack transmission mechanism. When the second servo motor 63 drives the second gear 62 to rotate, it can drive the movable frame 40 to move and adjust relative to the guide cantilever 21. In the second drive assembly 60, the second gear 62 is the driving element, and the second rack 61 is the driven element. When the second gear 62 starts to rotate under the driving force of the second servo motor 63, its tooth surface will mesh with the tooth surface of the second rack 61. As the second gear 62 continues to rotate, it will move along the extension direction of the second rack 61, thereby driving the movable frame 40 to move and adjust along the guide cantilever 21. In addition, the second servo motor 63 can perform precise displacement adjustment of the movable frame 40.
[0063] refer to Figure 5 The third drive assembly 70 includes a third rack 71, a third gear 72, and a third servo motor 73. The third rack 71 is fixed to the vertical arm 31 of the L-shaped arm 30 and extends in the vertical direction z. The third gear 72 is driven by the third rack 71. The third servo motor 73 is mounted on the moving frame 40 and is used to connect and drive the third gear 72 to drive the L-shaped arm 30 to move and adjust relative to the moving frame 40.
[0064] Specifically, the third drive assembly 70 is a gear and rack transmission mechanism. When the third servo motor 73 drives the third gear 72 to rotate, it can drive the L-shaped arm 30 to move and adjust relative to the moving frame 40. In the third drive assembly 70, the third gear 72 is the driving member, and the third rack 71 is the driven member. When the third gear 72 starts to rotate under the driving force of the third servo motor 73, its tooth surface will mesh with the tooth surface of the third rack 71. As the third gear 72 continues to rotate, the third rack 71 moves in the vertical direction z, thereby driving the L-shaped arm 30 to move and adjust relative to the moving frame 40. In addition, the third servo motor 73 can perform precise displacement adjustment of the L-shaped arm 30.
[0065] refer to Figure 6 The injection head 92 includes a first injection head 921 and a second injection head 922.

The second injection head 922 is movably mounted on the horizontal arm portion 32 and can be driven by the fourth drive assembly 80 to adjust the distance between it and the first injection head 921. During injection, the fourth drive assembly 80 can adjust the distance between the second injection head 922 and the first injection head 921 to more evenly inject the foaming material into the mold.

[0067] Specifically, the second injection head 922 is movably mounted to the horizontal boom portion 32 via the nut component 82, which can move and adjust the second injection head 922 along the horizontal boom portion 32. When the fourth servo motor 83 drives the lead screw 81 to rotate, the nut component 82 moves along the lead screw 81, thereby moving and adjusting the second injection head 922 to adjust its distance from the first injection head 921.
