Description

Technical Field

[0001] This utility model relates to the field of electric railway accessory processing technology, specifically a combination mold for processing electric railway accessories. Background Technology

[0002] Traditional processing techniques for power and railway equipment, especially for U-shaped iron accessories related to power equipment, mostly employ stamping. A search revealed that patent CN210877088U discloses a combined mold for processing power iron accessories. This tooling includes an upper mold base, a lower mold base, a lower mold bottom plate, and an unloading device. The upper mold base is fixedly connected to the press slide, and the unloading device includes an unloading movable block. The upper mold base is fixedly connected to the unloading movable block, and the lower mold base is fixedly connected to the press worktable. The mold is equipped with a chute in which the unloading movable block can be slidably placed. The chute is connected to the forming space of the lower mold base. It can automatically push the product off after forming by the unloading movable block, which solves the problem that the processed workpiece cannot be automatically removed. However, during the ejection process, the friction between the product and the sides is large, making ejection more difficult and energy-consuming. At the same time, the U-shaped iron accessory product is prone to tilting left and right during ejection, resulting in poor unloading stability. Therefore, a combined mold for processing electric iron accessories is designed to save unloading effort and improve unloading stability. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-6 A combined mold for processing electric iron accessories includes an upper mold base 3 and a lower mold base. The lower mold base includes a lower mold base 1 and two lower mold side seats 2 that slide symmetrically on both sides above the lower mold base 1. A U-shaped stamping groove that is adapted to the upper mold base 3 can be formed between the lower mold base 1 and the two lower mold side seats 2. The top sides of the two lower mold side seats 2 are provided with support roller groups that can be lifted and moved. The outer side of the support roller groups is provided with a limiting strip 4 with a support bar 5 at the bottom that can move left and right. The top surface of the support bar 5 is flush with the top surface of the lower mold side seat 2.

[0025] Specifically, the support roller assembly includes a guide frame 7 with a guide support roller 8 rotatably connected to its top. The bottom of the guide frame 7 is guided and slidably fitted with a support frame 9 fixedly installed on the lower die side seat 2. At the mid-positions of the guide frame 7 and the support frame 9, an upper magnetic block 10 and a lower electromagnetic block 11 with magnetic repulsion are respectively provided. The upper magnetic block 10 is fixedly installed on the guide frame 7. The bottom of the lower electromagnetic block 11 is fixedly connected to a lifting adjustment screw 12 threadedly connected to the support frame 9. By rotating the lifting adjustment screw 12, the distance between the lower electromagnetic block 11 and the upper magnetic block 10 can be easily adjusted. When the lower electromagnetic block 11 is de-energized, the magnetic repulsion between the upper magnetic block 10 and the lower electromagnetic block 11 disappears, thereby causing the guide frame 7 and the guide support roller 8 to descend to a height where the top surface is lower than the top surface of the lower die side seat 2, so that the iron metal strip rests on the lower die side seat 2 and the support strip 5.

[0026] Specifically, the limiting strip 4 is horizontally guided and slidably engaged with the lower mold side seat 2. The lower mold side seat 2 is rotatably connected to a translation adjustment screw 6 that is threaded to the bottom of the limiting strip 4. By rotating the translation adjustment screw 6, the translation adjustment screw 6 can be rotated clockwise or counterclockwise, which facilitates the left and right movement of the limiting strip 4 on the lower mold side seat 2.

[0027] Specifically, an adjustment slot is provided through the lower mold base 1 on both sides. Two hinge seats are fixedly connected in the adjustment slot, and a bidirectional screw 13 is rotatably connected between the two hinge seats. An adjustment motor 15 that drives the bidirectional screw 13 to rotate is also fixedly installed in the adjustment slot. An adjustment passage is opened above the two sides of the bidirectional screw 13 in the adjustment slot. Two feed sliders 14 that mesh with the bidirectional screw 13 are symmetrically arranged in the two adjustment passages. The top of the two feed sliders 14 are fixedly connected to the lower mold side seat 2 on their respective sides. When the adjustment motor 15 is started, the output shaft of the adjustment motor 15 rotates clockwise or counterclockwise, which facilitates the rotation of the bidirectional screw 13 clockwise or counterclockwise. This drives the two feed sliders 14 to move to the sides or to the middle, and in turn drives the two lower mold side seats 2 to move to the sides or to the middle.

[0028] Specifically, a fixed slider 16 is fixedly installed on the top of the upper die holder 3, and a fixed slide block 17 is also included that slides and guides the fixed slider 16. A positioning screw 18 is threaded onto the fixed slider 16, and a positioning screw hole 19 that matches the positioning screw 18 is provided on the fixed slide block 17. In use, the fixed slide block 17 can be fixed below the punch of the stamping equipment, and then the fixed slider 16 can be slid onto the fixed slide block 17. Then the positioning screw 18 can be screwed into the positioning screw hole 19 to fix the upper die holder 3. Due to the setting of the positioning screw 18 and the positioning screw hole 19, it is convenient to replace the upper die holder 3.

[0029] Specifically, the translation adjustment screw 6, the lifting adjustment screw 12, and the positioning screw 18 are all fixedly connected with adjustment knobs. By setting adjustment knobs, it is convenient to rotate and adjust the translation adjustment screw 6, the lifting adjustment screw 12, and the positioning screw 18 respectively.

[0030] In use, first adjust the distance between the limiting strips 4 on both sides and the support roller group on the same side according to the length of the iron metal strip to be stamped. Then, place the heated iron metal strip to be stamped on the two support roller groups and then lock it between the limiting strips 4 on both sides. Then, lower the support roller groups on both sides at the same time, so that the iron metal strip to be stamped is placed on the two lower die side seats 2 and the two support strips 5. Then, move the upper die seat 3 down to form a U-shaped stamping groove through the lower die base 1 and the two lower die side seats 2 to stamp into a U-shaped iron accessory product. Then, move the two lower die side seats 2 to the sides and then move the upper die seat 3 vertically upward. Finally, remove the U-shaped iron accessory product from the lower die base 1.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
