Description

Technical Field

[0001] The utility model relates to the field of lost foam castings, in particular to a lost foam casting of an automobile flip bracket. Background Art

[0002] Lost foam casting is a new casting method that combines paraffin wax or foam models with similar size and shape to the casting into a model cluster, brushes refractory paint and dries it, buries it in dry quartz sand and vibrates it to shape it, and pours it under negative pressure to vaporize the model. Liquid metal occupies the position of the model and forms a component after solidification and cooling.

[0003] At present, the flip parts of the automobile flip bracket made by lost foam casting are spliced ​​and assembled by welding or bolts in subsequent use, which will lead to a long assembly time and low assembly efficiency, thereby affecting the assembly of the entire bracket.

[0004] In this regard, in order to solve the technical problem that the assembly of the parts after casting is relatively complicated, the present application proposes a lost foam casting of an automobile flip bracket. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a lost foam casting of an automobile flip bracket. The two bracket castings can be quickly assembled through a snap-fit ​​structure, thereby reducing the splicing time between the castings and speeding up the assembly efficiency of the entire automobile bracket. The models of the two bracket castings to be spliced ​​are equal, so there is no need to open a separate mold for the casting, thereby facilitating casting.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] Furthermore, a slot is provided on one side of the bracket casting opposite to one end and away from the buckle, and the shape and size of the slot are consistent with the shape and size of the outer wall of the buckle.

[0012] Furthermore, the rotating assembly includes a T-shaped block fixedly connected to the bottom end of the outer wall of the flip rod. After the bracket castings are spliced, the inner wall will form a T-shaped groove, and the shape and size of the T-shaped block are consistent with the shape and size of the T-shaped groove.

[0013] Furthermore, the upper and lower ends of the inner wall of the T-shaped block are slidably connected with second latching teeth, and the shape and size of the second latching teeth are consistent with the shape and size of the first latching teeth.

The shape and size of the slot are consistent with the shape and size of the outer wall of the buckle 7. The bottom end of the outer wall of the flip rod 2 is fixedly connected with a T-block 9. After the bracket casting 1 is spliced, the inner wall will form a T-shaped slide groove 8. The shape and size of the T-block 9 are consistent with the shape and size of the T-shaped slide groove 8. The upper and lower ends of the inner wall of the T-block 9 are slidably connected with a second latch tooth 10. The shape and size of the second latch tooth 10 are consistent with the shape and size of the first latch tooth 6. The inner wall of the upper second latch tooth 10 is fixedly connected to the outer wall of the first connecting block 12, and the lower second latch tooth 10 is fixedly connected to the outer wall of the second connecting block 13. The teeth of the second latch tooth 10 are arranged on the opposite side, so that it can better cater to the gear of the first latch tooth 6, and then can perform two-way limiting, thereby ensuring the rotation angle positioning of the flip rod 2.

[0029] Specifically, the device will have a matching controller when in use, and the controller can independently control the hydraulic rod 11. When disassembling, first press the adjustment block 3 inward, which will push the adjustment block 3 inward and drive the clamping block 4 to slide inward and compress the first spring 5. At this time, the limit between the two spliced ​​bracket castings 1 will be released. At this time, the upper bracket casting 1 will be pulled out upward along the flip rod 2, and then the flip rod 2 will be pulled out upward along the inner wall of the lower bracket casting 1 to disassemble the component into three parts.

[0030] Reference Figure 4 and Figure 5, flip rod 2, the top end of the inner wall of the flip rod 2 is fixedly connected with a hydraulic rod 11, the bottom end of the hydraulic rod 11 is fixedly connected to a first connecting block 12, and a second connecting block 13 is provided at the bottom end of the first connecting block 12. The outer edges of the first connecting block 12 and the second connecting block 13 are slidably connected to the inner wall of the flip rod 2, and the first telescopic rod 15 is slidably installed on the front and rear sides of the bottom end of the first connecting block 12. The bottom ends of the first telescopic rod 15 are slidably installed on the bottom end of the second connecting block 13, and the second telescopic rod 16 is slidably installed on the top end of the second connecting block 13. The top of the second telescopic rod 16 is slidably installed on the bottom end of the first connecting block 12, and the middle inner walls of the first telescopic rod 15 and the second telescopic rod 16 are rotatably connected with a fixed rod 14 together, and the front and rear ends of the fixed rod 14 are fixedly connected to the inner wall of the flip rod 2.

[0031] Specifically, the first connecting block 12 and the second connecting block 13 expand or contract under the control of the hydraulic rod 11, thereby corresponding to the limiting and releasing of the limiting. To ensure complete limiting, the second latch tooth 10 on the upper side is arranged clockwise with the pointed end facing upward, and then forms a clockwise limit with the first latch tooth 6 on the upper side. Then the second latch tooth 10 at the bottom will be arranged counterclockwise with the pointed end facing downward, and then form a counterclockwise limit with the first latch tooth 6 on the lower side, thereby acting together with the clockwise limit at the upper end, thereby realizing the adjustment of the flip angle of the flip rod 2.

[0032] Working principle: After the bracket casting 1 is cast, the first tooth 6 of one of the bracket castings 1 is placed upwards, and then the T-block 9 of the flip rod 2 is forked into the inner wall of the bracket casting 1. Then the first tooth 6 on the other bracket casting 1 is placed downwards and installed downwards along the outer wall of the flip rod 2, and then a T-shaped slide 8 is formed between it and the bracket casting 1 at the lower end. At this time, the T-shaped slide 8 will fit with the T-block 9 on the flip rod 2. At this time, the buckle 7 on the bracket casting 1 will coincide with the slot on the other one. At this time, the buckle 7 will be squeezed with the block 4 and move the block 4 inward, thereby compressing the first spring 5. When the installation is completed, the buckle 7 will move to the lower side of the block 4, so that the block 4 will push the block 4 toward the buckle 7 under the reaction force of the first spring 5, thereby forming a restrictive relationship between the buckle 7 and the bracket. At this time, the assembly of the bracket The installation is completed. To ensure that the flip rod 2 does not rotate at will, and thus to ensure the required rotation angle, first rotate the flip rod 2 to the required angle, and then use the matching controller to control the hydraulic rod 11 to retract it. At this time, the hydraulic rod 11 will drive the first connecting block 12 to move upward, and the movement of the first connecting block 12 will drive the first telescopic rod 15 and the second telescopic rod 16 to slide, thereby increasing the longitudinal length of the first telescopic rod 15 and the second telescopic rod 16 and reducing the transverse length, which will cause the distance between the first connecting block 12 and the second connecting block 13 to increase, thereby driving the respective second latch teeth 10 to be stuck in the relative first latch teeth 6, thereby limiting the rotation of the second latch teeth 10, resulting in the rotation of the flip rod 2 being restricted, and then the flip rod 2 will be fixed at the required angle, thereby completing the directional flip.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
