[0002] Metal structural components are an important part of various mechanical equipment and building structures. They are usually made of metal materials and have excellent properties such as high strength, corrosion resistance, and wear resistance. Die casting molding equipment is required for the processing of metal structural components.

[0003] For example, a forming device for processing metal structural parts, authorized by announcement number CN220480208U, includes a support base, a bracket fixedly connected to the top of the support base, a hydraulic pump fixedly connected to the top of the bracket, a die-casting block fixedly connected to the bottom of the hydraulic pump, a fixing rod fixedly connected to the inner wall of the bracket, and a receiving groove formed on the inner wall of the fixing rod. However, this document still has shortcomings. In use, the support base, bracket, hydraulic pump, die-casting block, fixing rod, receiving groove, limiting groove, movable block, movable rod, and return spring improve the stability of die casting, prevent shaking, and facilitate buffering during die casting, avoiding damage caused by excessive impact and improving safety. However, after processing the metal structural parts, the formed metal structural parts tend to adhere to the inside of the forming groove, requiring manual removal, which is cumbersome. Furthermore, when processing metal structural parts with different structures, different forming equipment needs to be used, increasing the processing cost of the metal structural parts. Utility Model Content

[0004] The purpose of this invention is to solve the problem that formed metal structural parts are prone to sticking to the inside of the forming groove, and to propose a forming device for processing metal structural parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a forming device for processing metal structural parts, including a base and a top plate. The base is fixedly connected to the top plate by a support column. A lower mold is fixedly connected to the upper surface of the base. A hydraulic cylinder is fixedly installed inside the top plate. A back plate is fixedly connected to the hydraulic rod of the hydraulic cylinder. A demolding mechanism is provided below the back plate. An upper mold is fixedly connected to the lower surface of the back plate. A locking mechanism is provided inside the upper mold.

[0007] Preferably, the demolding mechanism includes racks, two racks are fixedly connected to the lower surface of the back plate, the racks mesh with gears, the gears are fixedly connected to one end of a rotating rod, the outer wall of the rotating rod is rotatably connected to the lower mold through a bearing, the other end of the rotating rod is fixedly connected to a first bevel gear, the first bevel gear meshes with a second bevel gear, a screw is fixedly connected above the second bevel gear, the outer wall of the lower end of the screw is rotatably connected to the lower mold through a bearing, the outer wall of the screw is threadedly connected to a threaded cylinder, and the upper ends of both threaded cylinders are fixedly connected to a support plate.

[0008] Preferably, the snap-fit ​​mechanism includes a support rod, the outer wall of which is slidably connected to the upper mold, a pin fixedly connected to the surface of the support rod, the outer wall of which is slidably connected to a groove provided in the support plate, the outer wall of the support plate is slidably connected to the upper mold, a connecting rod fixedly connected to the outer wall of the support plate, the outer wall of which is slidably connected to the upper mold, and a spring sleeved on the outer wall of the connecting rod, the two ends of which are fixedly connected to the upper mold and the connecting rod respectively.

[0009] Preferably, the end of the connecting rod is engaged with a slot provided in the connecting plate, and the outer wall of the connecting plate is fitted with a groove provided in the upper mold.

[0010] Preferably, a mold core is fixed to the lower surface of the connecting plate.

[0011] Preferably, a slider is fixedly connected to the outer wall of the back plate, the slider is slidably connected to the outer wall of the slide rod, and the upper end of the slide rod is fixedly connected to the top plate.

[0012] Preferably, the lower mold is provided with a sliding groove and a forming groove inside.

[0013] Preferably, the slide groove is clearance-fitted with the outer wall of the rack, the forming groove is slidably connected with the outer wall of the support plate, and the forming groove is clearance-fitted with the outer wall of the mold core.

[0014] The present invention discloses a forming device for processing metal structural parts, which has the following advantages: Through the cooperation between a rack, gear, rotating rod, first bevel gear, second bevel gear, screw, threaded cylinder, and support plate, the rack is inserted into the groove and drives the gear to rotate. The gear drives the rotating rod to rotate, the rotating rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the screw to rotate, the screw drives the threaded cylinder to move downward, the threaded cylinder drives the support plate to move downward, and the mold core is inserted into the forming groove to process and form the metal structural part. After the metal structural part is processed and formed, the hydraulic cylinder is activated in the reverse direction, the mold core and rack move upward, the rack drives the gear to rotate in the reverse direction, and then the support plate slides upward, lifting the processed metal structural part upward. The formed metal structural part does not stick to the inside of the forming groove, and there is no need to manually remove the formed metal structural part, making the operation relatively simple.

[0015] By coordinating the support rods, pins, support plates, connecting rods, and springs, pulling down the support rods on both sides causes the pins to move. The pins then drive the support plates to slide through the grooves within the support plates, which in turn drive the connecting rods to slide. The end of the connecting rod retracts into the upper mold and compresses the spring. The end of the connecting rod separates from the slot within the connecting plate, allowing the mold core and connecting plate to be removed. The desired mold core is then selected, and the connecting plate above the mold core is placed into the groove within the upper mold. The support rods on both sides are released, and the springs, under elasticity, drive the connecting rods to slide in the opposite direction. The end of the connecting rod inserts into the slot within the connecting plate, and the connecting plate is snapped into place inside the upper mold, thus achieving the installation of the mold core. The mold core can be replaced, eliminating the need to change forming equipment when processing metal structural parts with different structures, thereby reducing the processing cost of metal structural parts.
