DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0018] An embodiment of the utility model, as Figure 1 and Figure 2 As shown, a guide rail 3 fixedly connected to the frame 2 is provided on one side of the frame 2 close to the mold body 1, and a guide wheel mechanism is connected to one side of the mold body 1 close to the guide rail 3. The guide wheel mechanism includes a first connecting plate 4 arranged on the top of the mold body 1, and a second connecting plate 5 vertically arranged is connected to the side of the first connecting plate 4 away from the mold body 1. A guide wheel 6 abutting against the guide rail 3 is movably mounted on the second connecting plate 5, and a reset mechanism 8 is arranged on the second connecting plate 5. The guide wheel mechanism around the mold can reduce the shaking generated during the opening and closing process of the low-pressure machine, thereby improving the stability of the opening and closing process, ensuring the quality of the workpiece, and reducing safety hazards.
[0019] The first connecting plate 4 is fixed to the top of the mold body 1 by fixing bolts 41. A rectangular notch is provided on the first connecting plate 4 near the connection position with the second connecting plate 5. The top of the second connecting plate 5 is embedded in the notch of the first connecting plate 4 and is movably connected by the first rotating shaft 7. When the mold body 1 is affected by horizontal external force during the opening and closing process, a certain buffer force is generated to avoid the rigid connection from getting stuck.
[0020] The guide wheel 6 is movably mounted on the second connecting plate 5 via the second rotating shaft 61 . During the opening and closing movement of the mold body 1 , the guide wheel 6 is driven to move along the vertical direction of the guide rail 3 to reduce shaking.
[0021] The guide wheel 6 is a concave wheel structure, and the wheel surface of the guide wheel 6 fits the surface of the cylindrical guide rail 3, thereby increasing the contact area between the guide wheel 6 and the guide rail 3 and avoiding derailment.
[0022] The reset mechanism 8 includes an adjusting bolt 81 installed on the second connecting plate 5. A top cap 82 abutting against the mold body 1 is provided on the side of the adjusting bolt 81 close to the mold body 1. After the extending length of the adjusting bolt 81 is adjusted, the elastic member 83 and the mold body 1 are in the original position. An elastic member 83 is provided between the top cap 82 and the adjusting bolt 81. Specifically, the elastic member 83 adopts a spring structure. During the opening and closing process of the mold body 1, if a horizontal force is received, the external force acts on the top cap 82 to deform the elastic member 83. At the same time, the first connecting plate 4 and the second connecting plate 5 are offset at the position of the first rotating shaft 7 to avoid collision with the guide rail 3 and eliminate the influence of external force, so that the mold body 1 can also ensure smooth and stable opening and closing of the mold under the action of external force.
