Description

Technical Field

[0001] This utility model relates to the field of mold auxiliary equipment technology, and in particular to a gravity mold material support and positioning mechanism. Background Technology

[0002] In the stamping process, a support frame is often needed to support the sheet material to be processed. During production, the sheet material is placed on a certain mold surface before being pressed and deformed. However, if the mold surface is uneven, the sheet material will shift to one side due to gravity, causing it to be unbalanced and affecting the flowability of the sheet material during forming.

[0003] In existing material support systems, the material support method is rigid, meaning the height of the support platform is pre-adjusted to a predetermined value before the mold starts working and remains constant during mold operation. However, in some cases, the constant height of the support platform can cause the sheet material to warp, affecting its accuracy. For example, during stamping, after the upper die contacts the sheet material, it presses down on the edge of the cutting edge and continues to move downwards to complete the stamping process. However, the portion of the sheet material on the support platform of the material support system cannot move downwards. This causes deformation and warping of the sheet material in the area between the cutting edge and the support platform. The sheet material cannot be reused after one stamping, and the accuracy of repositioning and the shape of the sheet material will be affected.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gravity mold material support and positioning mechanism with simple and reasonable structure and reliable performance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A gravity-type mold material support and positioning mechanism includes two material support units arranged opposite to each other. Each material support unit includes a positioning seat, a positioning support frame disposed on the positioning seat, a material support rod rotatably mounted on the positioning support frame, and a gravity block disposed on the material support rod. The material support rod has a first state and a second state. When the material support rod is subjected to an external force that is greater than the gravity of the gravity block, the material support rod switches from the first state to the second state. When the external force disappears, the material support rod switches from the second state to the first state.

[0008] As a further embodiment of this utility model, one end of the material support rod forms a material support end, and the other end forms a load-bearing end. The material support rod is rotatably mounted on the positioning support frame near the material support end, and the gravity block is installed on the load-bearing end.

[0009] As a further embodiment of this utility model, the material support rod is rotatably mounted on the positioning support frame via a rotating shaft.

[0010] As a further embodiment of this utility model, an installation notch is provided on the side wall of the end of the positioning support frame away from the positioning seat, and the material support rod is rotatably mounted on the bottom wall of the installation notch.

[0011] As a further embodiment of this utility model, the sidewall of the mounting notch has a horizontal stop surface that cooperates with the material support rod in the first state and an inclined stop surface that cooperates with the material support rod in the second state.

[0012] As a further embodiment of this utility model, the included angle between the material support rod in the first state and in the second state is 70 degrees.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Due to the above structural design, which involves two material support units arranged opposite each other, each material support unit includes a positioning seat, a positioning support frame, a material support rod, and a gravity block. Before processing, the material sheet is placed on the two material support rods, and the material sheet is placed stably without tilting or falling. During processing, when the material sheet is subjected to an external force greater than the weight of the gravity block, the material support rod switches from the first state to the second state, which can prevent the material sheet from warping and can simultaneously meet the requirements of convenient loading and unloading and flexible material support. When the material sheet is removed from the material support rod, the external force disappears, and the material support rod switches from the second state to the first state.

[0027] The features and performance of this utility model will be further described in detail below with reference to the embodiments. Example

[0028] like Figure 1-3 As shown, this application discloses a gravity-type mold material support and positioning mechanism, which includes two material support units 10 arranged opposite to each other, and each material support unit 10 includes a positioning seat 11;

[0029] A positioning support frame 12 is provided on the positioning seat 11. Specifically, the positioning support frame 12 has an installation notch 121 on the side wall of the end away from the positioning seat 11. The side wall of the installation notch 121 has a horizontal stop surface 1211 that cooperates with the material support rod 13 in the first state and an inclined stop surface 1212 that cooperates with the material support rod 13 in the second state.

[0030] A material support rod 13 is rotatably mounted on the positioning support frame 12. Specifically, one end of the material support rod 13 forms a material support end 131, and the other end forms a load-bearing end 132. The material support rod 13 is rotatably mounted on the bottom wall of the positioning support frame 12 via a rotating shaft 133 near the material support end 131.

[0031] And a gravity block 14 disposed on the load-bearing end 132 of the material support rod 13. Specifically, the gravity block 14 and the positioning support frame 12 are located on the same side of the material support rod 13.

[0032] The material support rod 13 has a first state and a second state. When the material support rod 13 is subjected to an external force that is greater than the weight of the gravity block, the material support rod 13 switches from the first state to the second state. When the external force disappears, the material support rod 13 switches from the second state to the first state. Specifically, in the first state, the material support rod 13 is in contact with the horizontal stop surface 1211 and is in a horizontal state; in the second state, the material support rod 13 is in contact with the inclined stop surface and is in an inclined state.

[0033] In this embodiment, the sheet is placed on the supporting ends of the two supporting rods 13. The weight of the sheet on the supporting rods 13 is less than the weight of the gravity block 14. Therefore, the sheet can be placed stably without tilting or falling. During processing, the upper mold begins to apply force to the sheet. The sheet is continuously subjected to an external force greater than the weight of the gravity block. The supporting end 131 of the supporting rod 13 begins to descend, which in turn causes the load-bearing end 132 of the supporting rod 13 to rise. This allows the supporting rod 13 to switch from the first state to the second state, which can prevent the sheet from warping and simultaneously meet the requirements of convenient loading and unloading and flexible support. When the sheet detaches from the supporting rod 13, that is, after the sheet falls, the external force disappears, and the supporting rod 13 switches from the second state to the first state under the action of the gravity block 14.

[0034] As a preferred embodiment, the angle between the material support rod 13 in the first state and the second state is 70 degrees, thereby limiting the stroke of the material support rod 13.

[0035] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art, and has the advantages of simple and reasonable structure.

[0036] It features reliable performance and low cost.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
