When manufacturing a large number of products, the same product can be mass-produced by using the upper and lower molds, effectively improving industrial manufacturing efficiency;

[0004] During use, the forming stamping device used in ferrous metal casting is not convenient for positioning the mold, especially when the mold is replaced multiple times in small batches, resulting in low production efficiency and inconvenience in forming effective protection during the stamping process;

[0005] In order to overcome the above defects, prior art 1 (Chinese patent application with application number CN202221629104.5 and application date 2022-06-28) is a forming stamping device for ferrous metal casting, which prevents sputtering through a sealed protective shell and an operating door, has good safety, and the built-in sound-absorbing cotton adopts a wavy sound-absorbing cotton (brand is Donghong, model is D620B), which is full of many small gaps and semi-open hole structures, which can absorb a large amount of incident sound wave energy, attenuate the sound waves, reduce the interference and reverberation of reflected sound, and effectively absorb the noise emitted by the equipment. The guide slider on the guide slide rod supports the operating door for easy opening; the operating door is opened electrically through the driving mechanism, which saves effort, and the grating can be used to detect when the operating door is closed to prevent pinching, and the built-in tempered glass through the observation window has strong rigidity, which is also convenient for observation and protection;

[0034] Preferably, the forming punching device for ferrous metal casting also discloses a method for using the forming punching device, and the specific method steps are as follows:

[0035] The first step is to use it for forming and stamping ferrous metals. The ferrous metal parts can be stably placed in the mold core assembled by the lower template, and the mold cavity assembled by the upper template is controlled to form a mold clamping and stamping between the mold core, and the center waste of the stamping is discharged through the discharge piece. Before the mold core is assembled and used, the moving part is pulled to form a limit engagement with the positioning rod, and then the mold core is controlled to be nested on the upper side of the inner surface of the mold core through the positioning column, and the control handle is rotated to rotate the coaxial adjustment turntable, and the torsion spring is controlled to contract, so that the connecting rod connected to the lower side of the turntable is synchronized with the cam to control the positioning The positioning rod is limited to slide, and the positioning rod is separated from the engagement with the moving part, so that the moving part can be controlled to slide to the rear side of the lower template through the contraction of the installed spring sheet, and the extrusion part 1 installed on the moving part will squeeze the extrusion part 2, so as to control the clamping part installed on the extrusion part 2 to slide, and the clamping part is clamped on the side of the inner surface of the mold core, so as to control the stability of the mold core assembly, and when the mold core is positioned and engaged, the handle is separated from the control, so that the positioning rod and the moving part can be elastically adjusted to form a positioning engagement, so as to prevent separation during stamping and avoid shaking of the mold core;

[0036] The second step is to start the mold closing and stamping between the mold core and the mold cavity. First, the motor assembled in the housing is controlled to rotate the shaft through the output shaft, so that the bevel gear set can be controlled to rotate the spur gear in linkage. When the spur gear rotates, it meshes with the rack installed on the protective door, thereby controlling the sliding of the protective door and controlling the symmetrical protective door to move in the center. When the protective door moves, the roller installed in cooperation with the support track installed on the housing forms a limited sliding, which improves the support stability of the protective door and controls its convenient movement.

[0037] The third step is to control the fixing plate of the upper template assembly to move the wire rope upward after the mold core and the mold cavity are closed and the mold is opened, so as to control the shaft body for winding the wire rope to unfold counterclockwise, and control the spur gear 2 assembled on the shaft body to rotate counterclockwise on the inner surface of the support frame, and synchronously mesh to drive the spur gear 2 to mesh with the rack 2, and the rack 2 will slide on the inner surface of the support frame, and control the front end of the push rod assembled on the rack 2 to approach the middle section of the outer surface of the mold core, and the push rod will squeeze the reset spring on the inner surface of the support frame, and synchronously drive the oil inlet pipe to move, so as to control the oil spray head installed on the push rod to form a lubrication setting for the fitting surface of the mold core and the mold cavity, or to lubricate the upper surface of the ferrous metal parts.

[0039] 1. A positioning nesting mechanism is provided. The spring sheet installed by the slidable moving frame can effectively reset through the elasticity of the spring sheet when the moving frame is separated from the limit position of the positioning rod, so as to drive the extrusion member 1 and the extrusion member 2 to form an oblique extrusion slide, thereby controlling the extrusion member 2 to control the clamping member to form a limit engagement with the mold core, so that the mold core is initially nested through the positioning column to form a positioning engagement for use, thereby preventing the mold core from falling off;

[0040] Furthermore, after the positioning rod is disengaged and the moving part is squeezed and used, the position of the connecting rod is controlled by the turntable, so as to adjust the positioning rod and the moving part to form a limited engagement, thereby preventing the moving part from sliding and preventing the mold core from being disengaged from the engagement position;

[0041] 2. A limited movement mechanism is provided, and the stability of the use of the protective door is controlled by the cooperation of the assembled rollers and the support rails through the symmetrically assembled protective door, and the rack 1 installed in conjunction with the protective door is effectively matched with the bevel gear assembled with the rotating shaft and the linked spur gear 1 to control the stability of the protective door installed with the rack 1, thereby improving the stability of the movement of the protective door;

[0042] 3. A support frame is provided for facilitating positioning and assembly. When in use, the steel wire rope connected by winding up is coordinated with the movement of the upper template assembled by the fixed plate to effectively control the unfolding of the steel wire rope, and the spur gear 2 and the rack 2 are synchronously adjusted to form a synchronous adjustment, which can effectively control the push rod assembled by the rack 2 to form a synchronous adjustment, and control the oil spray head to move to the middle section of the mold core to form an oil spray lubrication effect;

[0043] Furthermore, when the rack 2 moves, the elastic control between the push rod and the reset spring can be used to form an elastic reset when the wire rope contracts, thereby controlling the synchronous reset of the oil injection head. BRIEF DESCRIPTION OF THE DRAWINGS
