[0027] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0028] like Figure 1-8 The shown integrated extrusion equipment for automobile decorative strips includes a fixed mold 1 with an open upper surface, and a lifting mechanism 4 is fixedly connected to the corners of the fixed mold 1. In fact, through holes 108 are opened at the four corners of the fixed mold 1. The lifting mechanism 4 includes a cylinder 401 fixedly connected to the through hole 108, and a movable telescopic rod 402 is inserted into the cylinder 401. Under normal circumstances, the telescopic rod 402 and the cylinder 401 will form a hydraulic cylinder structure, which can generate a large pressing force. The movable end of the lifting mechanism 4 is fixedly connected to the movable mold 2. In fact, the movable mold 2 is connected to the upper end of the telescopic rod 402.

[0029] An injection mechanism 3 is provided on one side of the fixed mold 1, and a demoulding mechanism 5 is provided on the other side. The injection mechanism 3 is also fixedly provided, and is used to heat the raw material of the decorative strip into a liquid state and pressurize the raw material with good fluidity to make the raw material ejected. The specific structure of the demoulding mechanism 5 includes a flipping claw 520, which is used to lift and throw out the formed automobile decorative strip. The flipping claw 520 includes a swing arm 522 rotatably connected to the fixed mold 1, and one end of the swing arm 522 can be swung into the fixed mold 1, and the other end is always located outside the fixed mold 1. The front of the fixed mold 1 has a second articulated frame 107, and the bottom surface of the corresponding swing arm 522 has a rotating shaft 523, which just cooperates with the second articulated frame 107 to form a rotating pair. It should be noted that the extension direction of the swing arm 522 is perpendicular to the rotation direction, so that the probability of the swing arm 522 interfering with other components when rotating is relatively small. The upper surface of the fixed mold 1 is provided with a main mold The cavity 104 is used to constrain the shape of the flowing raw material. The fixed mold 1 is also provided with a fitting groove 105 connected to the main cavity 104. The position of the fitting groove 105 is lower than the main cavity 104 and is used to accommodate the swing arm 522 rotated to a horizontal position. The upper surface of the fixed mold 1 is provided with a limiting slide 102 continuous with the fitting groove 105, which is just for the swing arm 522 to pass through and limit the freedom of movement of the swing arm 522, so that the swing arm 522 is more stable when rotating. The lower surface of the movable mold 2 is provided with a positioning plate 202. When the lower surface of the movable mold 2 contacts the upper surface of the fixed mold 1, the positioning plate 202 is just fitted with the limiting slide 102 and pressed tightly against the upper surface of the swing arm 522. The surface of the swing arm 522 is provided with a secondary cavity 524 that can be continuous with the main cavity 104. When the swing arm 522 is horizontal, the secondary cavity 524 is completely aligned with the main cavity 104 to form a complete mold cavity.

[0030] A cylinder 510 is connected between one end of the swing arm 522 located outside the main cavity 104 and the bottom surface of the fixed mold 1, which is used to drive the swing arm 522 to rotate relative to the fixed mold 1. Normally, a pair of swing arms 522 are provided, and the two swing arms 522 are parallel to each other, and the ends of the two swing arms 522 extending outside the fixed mold 1 are fixedly connected to a bridging plate 521, and the lower surface of the fixed mold 1 has a first articulated frame 106, one end of the cylinder 510 is rotatably connected to the first articulated frame 106, and the other end is rotatably connected to the bridging plate 521, and the lower surface of the fixed mold 1 is also provided with a receiving groove 109, which just accommodates the tilted cylinder 510.

[0031] The fixed mold 1 is also provided with a guide channel 103 connected to the main cavity 104, which is used to introduce the pressurized decorative strip material into the cavity. The upper surface of the fixed mold 1 is provided with a relief groove 101 connected to the guide channel 103, which can effectively reduce the obstruction of the molded part by the fixed mold 1 during demolding, making the demolding process smoother. The lower surface of the movable mold 2 has a sealing plate 201. When the lower surface of the movable mold 2 contacts the upper surface of the fixed mold 1, the sealing plate 201 fits perfectly with the relief groove 101 and is in close contact with the inner bottom surface of the relief groove 101 to form a sealing surface, which can effectively prevent the flowing raw material liquid from overflowing. The injection mechanism 3 injects the decorative strip material into the main cavity 104 and the auxiliary cavity 524 through the guide channel 103. After the cavity is filled, the raw material liquid will gradually cool to form a stable automobile decorative strip.

[0032] Working principle: When working, the lifting mechanism 4 first moves the movable mold 2 down to close the mold with the fixed mold 1, the sealing plate 201 is completely aligned with the clearance groove 101, the positioning plate 202 presses the swing arm 522 into the limiting slide groove 102, the injection mechanism 3 is started, and the hot-melt flowing material is squeezed into the mold cavity formed by the main cavity 104 and the auxiliary cavity 524 through the guide channel 103 until the mold cavity is filled. After the material cools down, the movable mold 2 rises to the upper limit again under the drive of the lifting mechanism 4, and the cylinder 510 is started and The swing arm 522 contracts, causing the swing arm 522 to flip upward, lifting the molded part in the main cavity 104, and the molded part flips along with the swing arm 522. Since the rotation range of the swing arm 522 is limited, the swing arm 522 will suddenly stop when it rotates to the limited position, and the molded part will break away from the auxiliary cavity 524 under the action of its own inertia, realizing rapid unloading. After unloading is completed, the flipping claw 520 returns to the initial position when the cylinder 510 extends, and the movable mold 2 descends again to close the mold with the fixed mold 1, and the next round of extrusion operation can be carried out.

Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
