Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts molds, in particular to an automobile chassis bracket mold. Background Art

[0002] The automobile chassis is connected to various components such as suspension and exhaust. The automobile chassis connects various components such as suspension and exhaust through brackets, and the brackets of the automobile chassis are manufactured through mold stamping.

[0003] The automobile chassis bracket is cut and stamped by a sheet metal multi-stamping machine using a mold. The sheet metal stamping and cutting process will produce scraps, which will fall onto the preset inclined rack of the mold, and the scraps will be guided to the outside by the inclined rack. The scraps on the upper part of the inclined rack will also stay, which will block the waste export of the mold. Usually, people use hooks to dig out the scraps to promote the downward movement of the scraps. The scrap inclined rack of the mold is located in a small space, and the distance between people and the mold also needs to be kept at a safe distance. It is even more inconvenient for people to use long hooks to dig out the scraps. Summary of the invention

[0004] The disclosed embodiment relates to an automobile chassis bracket mold, in which the rotation of the side cam guides the lower bracket and the waste guiding inclined frame to move back and forth, and the waste guiding inclined frame moves back and forth to guide the waste on the top to fall, thereby reducing the accumulation of waste on the upper part of the waste guiding inclined frame, and eliminating the need for personnel to use hooks to dig out the waste. The forward and backward movement of the waste guiding inclined frame can also push the outer waste to move, and also avoid the waste gathering and clogging on the top of the machine tool in front of the mold.

[0005] In a first aspect of the present disclosure, a vehicle chassis bracket mold is provided, which specifically includes: a lower mold frame, a waste guiding inclined frame and an upper mold frame, wherein a waste guiding inclined frame is arranged at the lower part of the lower mold frame, an upper mold frame is arranged above the lower mold frame, a lower stamping mold is fixed on the top of the lower mold frame, side buffer columns are vertically penetrated and slid on both sides of the lower mold frame, a supporting spring with a spiral structure is fixed on the upper part of the side buffer column, the lower end of the side buffer column is fixedly connected to a lower rack, a central rotating shaft is rotatably provided on the inner side of the lower part of the lower mold frame, side cams are fixed on both sides of the central rotating shaft, and a rotating lower pulley is arrayed on both sides of the lower part of the lower mold frame.

[0006] In at least some embodiments, the lower end of the upper support spring of the side buffer column is fixed to the top of the lower mold frame, and the lower rack is located at the lower part of the lower mold frame.

[0007] In at least some embodiments, the waste guiding inclined frame is a Z-shaped structure with an inclined surface from high to low, and L-shaped lower brackets are fixed on both sides of the lower part of the waste guiding inclined frame. The lower bracket is provided with a cylindrical sliding rod and is slidably connected to the inner side of the lower part of the lower mold frame.

[0008] In at least some embodiments, the bottom of the lower bracket is slidably connected to the lower pulley, a support spring is fixed on the inner side of the lower bracket, and the tail end of the support spring on the inner side of the lower bracket is fixed to the lower mold frame.

[0009] In at least some embodiments, the lower rack is meshed with a gear fixed to the central rotating shaft. When the lower rack moves vertically, the central rotating shaft and the side cam rotate circumferentially, and the side cam slides to push the lower bracket to move. The lower bracket relies on the support spring to reset and maintain contact with the side cam, and the stamping force of the upper mold frame is used to complete the forward and backward movement of the waste guiding inclined frame.

[0010] In at least some embodiments, the lower bracket and the side cam slide, and the support spring on the inner side of the lower bracket supports the lower bracket and the side cam to keep them in contact, and the rotation guidance of the side cam and the support of the support spring drive the lower bracket and the waste guiding inclined frame to complete the reciprocating movement back and forth, and the forward and backward movement of the waste guiding inclined frame promotes the waste on the top inclined surface to slide and fall.

[0011] In at least some embodiments, an upper stamping die is fixed at the bottom of the upper die frame, and the upper stamping die is vertically above the lower stamping die. The stamping machine drives the upper die frame and the upper stamping die to move downward and perform stamping with the lower stamping die, and the upper die frame is vertically above the side buffer column.

[0012] The utility model provides a car chassis bracket mold, which has the following beneficial effects:

[0013] The rotation of the side cam guides the lower bracket and the waste guiding inclined frame to move back and forth. The waste guiding inclined frame moves back and forth to guide the waste on the top to fall, reducing the accumulation of waste on the upper part of the waste guiding inclined frame. There is no need for personnel to use hooks to dig out the waste. The forward and backward movement of the waste guiding inclined frame can also push the outer waste to move, avoiding the waste gathering in the front and causing blockage.

[0014] When the upper mold frame is stamping, the side buffer column and the lower rack are pressed downward, and the lower rack drives the central shaft and the side cam to rotate. The stamping force of the upper mold frame is used to complete the forward and backward movement of the waste guiding inclined frame. No additional motor or other power source is required, which is conducive to controlling the mold cost. BRIEF DESCRIPTION OF THE DRAWINGS
