[0026] Example:

[0027] This embodiment discloses a mold changing trolley.

[0028] Figure 1 This is the axonometric view of the mold changing trolley of the utility model. Figure 1 As shown, the mold changing trolley includes a body 1, a platform 2 and a cylinder 3. The body 1 is a hollow structure with an opening at the upper end. A plurality of rollers 13 are rotatably arranged inside, and the upper ends of the rollers 13 are higher than the upper end of the body 1. The platform 2 is mounted on the upper ends of the rollers 13. The cylinder 3 has a cylinder body 31 and a piston 32 telescopically connected to the cylinder body 31. The cylinder body 31 is connected to the inner wall of the body 1, and the piston 32 is connected to the lower end of the platform 2.

[0029] Figure 2 It is a schematic diagram of the structure of the mold changing trolley of the utility model from a top view. Figure 3 for Figure 2 Section view at AA. Figure 4 To illustrate 3, enlarge the image at point A. Figure 5 This is a schematic diagram of the structure of the roller in the mold changing trolley of the utility model. Figure 2 to Figure 5As shown, exemplarily, the vehicle body 1 includes a support rod 11 and a support plate 12, both of which are connected to the vehicle body 1 and are arranged parallel to the length direction of the vehicle body 1. Among them, the roller 13 is rotatably arranged between the support plate 12 and the inner wall of the vehicle body 1 and arranged on both sides of the support rod 11 along the length direction of the vehicle body 1. The roller 13 includes a rotating shaft 133 and a bearing 131. The rotating shaft 133 is fixed through the support rod 11 and fixed to the inner wall of the vehicle body 1, and the bearing 131 is sleeved on the rotating shaft 133, and the bearing 131 and the rotating shaft 133 are locked by a retaining ring. Preferably, a screw 132 is also provided to pass through the support plate 12 and is threadedly connected to the rotating shaft 133 to improve the supporting strength of the roller 13. There are two cylinders 3, which are arranged on the inner wall of the vehicle body 1 in the width direction at intervals and are parallel to the length direction of the vehicle body 1.

[0030] like Figure 1 and Figure 2 As shown, further, the cylinder 31 is hinged to the inner wall of the vehicle body 1, and the piston 32 is hinged to the lower end of the platform 2. Specifically, the cylinder 31 can rotate in a vertical plane relative to the inner wall of the vehicle body 1, and the piston 32 can rotate in a vertical plane relative to the platform 2. When the mold changing trolley is overloaded or has been in use for a long time, the platform 2 and the roller 13 may sink. The hinge can prevent the cylinder 3 from bending or breaking under the action of the sinking force, thereby increasing the service life of the equipment.

[0031] Figure 6 for Figure 2 Section view at BB. Figure 2 and Figure 6 As shown, further, the platform 2 includes a baffle 21, which is arranged on both sides of the lower end of the platform 2 along the length direction and is located inside the vehicle body 1. The vehicle body 1 includes a travel switch 14, which is arranged on the inner wall of the vehicle body 1 and corresponds to the baffle 21. When the piston 32 of the cylinder 3 is extended or retracted, the baffle 21 at the lower end of the platform 2 triggers the travel switch 14, and the travel switch 14 controls the cylinder 3 to stop working, so as to limit the movement of the platform 2, prevent the platform 2 from extending too much and causing rollover or collision with external equipment, and improve the safety of the equipment.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, further, the mold changing trolley includes a steering wheel assembly 4, which is arranged at the lower end of the body 1 and arranged along the width direction of the body 1 to drive the body 1 to move. Specifically, the steering wheel assembly 4 is arranged at the four corners of the lower end of the body 1, has the advantages of high bearing capacity and flexible steering, and the steering wheel assembly 4 can adopt a commercially available AGV steering wheel.

[0033] In this embodiment, after the vehicle body 1 is moved into position, the piston 32 of the cylinder 3 is telescopically driven to drive the platform 2 to move left and right, so as to adjust the position of the mold on the platform 2 and improve the installation accuracy of the mold. The mold changing trolley does not need to rely on the installation accuracy of the ground rail and whether the trolley model matches, making the mold changing trolley versatile.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
