[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, an embodiment of the present application provides a small double-station mold changing vehicle, including an AGV vehicle, on which a vehicle body 1 and a mold changing assembly 2 are provided. The mold changing assembly 2 is slidably mounted on the top of the vehicle body 1, and two accordion covers 3 for dust prevention are provided at both ends of the mold changing assembly 2. One end of the accordion cover 3 is connected to the mold changing assembly 2, and the other end of the accordion cover 3 is connected to the vehicle body 1.

[0021] like Figure 2 As shown, the mold changing assembly 2 includes a linear module 21, a sliding plate 22 and two mold changing stations 23. The linear module 21 is installed on the vehicle body 1 and is located below the sliding plate 22. The driving end of the linear module 21 is connected to the sliding plate 22. The two ends of the bottom surface of the sliding plate 22 slide with the vehicle body 1. The two mold changing stations 23 are installed on the sliding plate 22. The linear module 21 is used to drive the sliding plate 22 to drive the two mold changing stations 23 to move horizontally.

[0022] Specifically, a new mold is placed at one mold-changing station 23 of the AGV, while the other mold-changing station 23 is vacant. When the AGV moves to a designated position near one side of the injection molding machine, the linear module 21 drives the sliding plate 22 to move the vacant mold-changing station 23 to the side of the injection molding machine, docking the mold-changing station 23 with the injection molding machine. The push-pull assembly 231 of the mold-changing station 23 pulls the completed mold in the injection molding machine along the roller assembly 232 and guide assembly 233 to the mold-changing station 23, and the limit assembly 234 limits the mold. The linear module 21 drives the mold-changing station 23 with the new mold to the side of the injection molding machine. The push-pull assembly 231 of the mold-changing station 23 pushes the new mold along the roller assembly 232 and guide assembly 233 into the injection molding machine, completing the mold change operation. During this period, when the linear module 21 drives the sliding plate 22 to move, the accordion covers 3 at both ends of the sliding plate 22 can be extended and retracted along with the sliding plate 22 .

[0023] In the above structure, the linear module 21 drives the sliding plate 22 to move the two die-changing stations 23, enabling the switching of the die-changing stations 23 and requiring only a single positioning of the AGV. Furthermore, the use of an accordion cover 3 not only does not affect the movement of the die-changing stations 23 but also protects the vehicle body 1 from dust. This small dual-station die-changing vehicle has a simple structure and is easy to operate. It not only reduces the number of positioning operations but also significantly improves die-changing efficiency.

[0024] like Figure 1 As shown, in one embodiment, the mold changing station 23 of the small double-station mold changing vehicle includes a push-pull assembly 231, a roller assembly 232 and a guide assembly 233. The push-pull assembly 231 is located on one side of the roller assembly 232, and the guide assembly 233 is located on the side of the push-pull assembly 231 away from the roller assembly 232. The push-pull assembly 231 includes a sprocket chain drive mechanism 100, a push-pull track 101 and a hook assembly 102. The sprocket chain drive mechanism 100 is installed on one side of the sliding plate 22, and the driving end of the sprocket chain drive mechanism 100 is connected to the hook assembly 102. The hook assembly 102 slides with the push-pull track 101. The sprocket chain drive mechanism 100 is used to drive the hook assembly 102 to move horizontally along the push-pull track 101. The sprocket chain drive mechanism 100 includes a motor and a sprocket chain transmission mechanism. The motor's drive end is connected to the sprocket chain transmission mechanism. The motor drives the sprocket chain transmission mechanism to drive the hook assembly 102 along the push-pull track 101 to move out of the vehicle body 1 and pull the mold out of the injection molding machine, so that one end of the mold is located on the guide assembly 233 and the other end of the mold is located on the roller assembly 232. The mold moves along the roller assembly 232 and the guide assembly 233 to the mold change station 23. The motor drives the sprocket chain transmission mechanism to drive the hook assembly 102 along the push-pull track 101 to one side of the mold, so that the hook assembly 102 hooks into the mold's positioning hole. The motor then drives the sprocket chain transmission mechanism to drive the hook assembly 102 to push the mold out of the mold change station 23 along the guide assembly 233 and the roller assembly 232, and transfer it into the injection molding machine. The arrangement of the mold change station 23 facilitates the push-pull operation of the mold, thereby improving the efficiency of mold change.

[0025] like Figure 3As shown, in one embodiment, the hook assembly 102 of the small dual-station mold-changing vehicle includes a hook 001, a hook seat 002, and a first cylinder 003. The hook 001 is hingedly connected to the hook seat 002, and the first cylinder 003 is mounted on the hook 001. The first cylinder 003 is used to drive the hook 001 to rotate upward around the hook seat 002. When the sprocket chain drive mechanism 100 drives the hook assembly 102 along the push-pull track 101 to one side of the mold, the first cylinder 003 drives the hook 001 to rotate upward around the hook seat 002. The first cylinder 003 releases the hook 001, allowing the hook 001 to hook into the mold's positioning hole. This arrangement facilitates driving the hook 001 to hook into the mold's positioning hole, as well as driving the hook 001 to release the mold's positioning hole, thereby achieving push-pull operations on the mold.

[0026] like Figure 2 As shown in one embodiment, the roller assembly 232 of the small dual-station die-changing vehicle includes two fixed plates 103, between which a plurality of rollers 104 are rotatably mounted. Nine rollers 104 are spaced apart between the two fixed plates 103, with the ends of the rollers 104 rotatably connected to the two fixed plates 103. The arrangement of the rollers 104 reduces friction with the die, improving die movement efficiency.

[0027] like Figure 2 As shown in one embodiment, the guide assembly 233 of the small dual-station die-changing vehicle includes two guide plates 105, with a plurality of rollers 106 rotatably positioned between the two guide plates 105. Nine rollers 106 are interspaced between the two guide plates 105, with each end of the nine rollers 106 rotatably connected to the two guide plates 105. The guide plates 105 provide guidance for one end of the die. The rollers 106 also reduce friction with the die, improving die movement efficiency.

[0028] like Figure 2 As shown, in one embodiment, a limit assembly 234 is provided on the guide assembly 233 of the small dual-station die-changing vehicle. The limit assembly 234 comprises a second cylinder and a stopper. The second cylinder is mounted on the vehicle body 1, and its drive end is connected to the stopper. The second cylinder is used to drive the material stopper to limit the position of the mold. After the two ends of the mold are moved along the guide assembly 233 and roller assembly 232 to the die-changing station 23, the second cylinder at one end of the guide assembly 233 drives the stopper upward to limit the mold. This arrangement prevents the mold from shaking and falling during the movement of the AGV.

[0029] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
