Description

Technical Field

[0001] The utility model belongs to the technical field of drawing dies, and in particular relates to a drawing tool guide structure for a front section of a front cabin reinforcement plate. Background Art

[0002] When the drawing die is in use, the upper die is manually closed on the lower die. Because the upper die will definitely shake and swing during this process, it is very likely to cause collision between the upper and lower mold surfaces, thereby damaging the working surface of the die, and ultimately causing the drawn product to have defects, or the risk of not being able to be drawn smoothly. The working surface of the drawn workpiece has high requirements, which reduces the quality of the finished product. When demolding, the blank is also stuck between the locating pins of the mold due to the outward drawing force, resulting in the blank being not demolded smoothly.

[0003] To this end, a drawing die guide structure with the announcement number "CN213671470U" includes an upper die and a lower die arranged above and below, a die head is fixed on the upper die, a plurality of cavities are provided in the upper die, vertical guide grooves connected to the cavities are provided on opposite sides of the cavities, a sliding hole connected to the cavity is provided at the bottom of the upper die, a pre-guide column is vertically provided in the sliding hole, one end of the pre-guide column is provided in the cavity and is connected to a sliding plate that can slide vertically in the cavity, guide blocks matching the guide groove are provided on both sides of the sliding plate, the side surfaces of the guide blocks contact the groove walls of the guide groove, and a spring is connected between the top of the sliding plate and the cavity; a pre-guide groove is provided on the top of the lower die opposite to the pre-guide column, the groove depth of the pre-guide groove is less than the length of the pre-guide column extending out of the bottom of the upper die when the spring is in a balanced state; matching toothed blocks and toothed grooves are also provided between the bottom of the upper die and the top of the lower die, a plurality of clamping blocks are provided on the bottom edge of the upper die, and a plurality of matching notches corresponding to the clamping blocks are provided on the top edge of the lower die.

[0004] However, for the above-mentioned drawing die guide structure, although the upper die is pressed down, the bottom of the pre-positioning column is inserted into the pre-positioning groove at the top of the lower die, and the top of the pre-positioning column pushes the sliding plate to slide up, compressing the spring to perform preliminary positioning on the downward pressing process of the upper die, and the guide blocks on both sides of the sliding plate slide vertically along the guide groove to ensure the stability of sliding. However, there are still the following more obvious defects during use: However, the compression spring is compressed in the process of the mold being guided to close the mold by the pre-guide column. Since the mold needs to continuously open and close the mold for processing the workpiece, the pre-guide column will be continuously compressed and reset, causing the compression spring to elastically push and shrink the pre-guide column to fail, and then the compression spring cannot elastically compress the pre-guide column to accurately close the mold.
