Because supporting baseplate 100, support floor, mould punching press portion 300 all can be the sheet metal component and make, or form by the sheet metal component concatenation. In the actual production process, the sheet metal parts suitable for batch production can be adopted, and then the sheet metal parts are spliced into the die body.
When making for the mould body, carry out the die sinking production, the mould body of mode production through the sheet metal component concatenation is fixed can effectively get save time. Simultaneously, because the mould body that the die sinking production obtained is solid structure, the used material of mould body can also be practiced thrift in the production of the mould body of the mould this embodiment in this embodiment.
As shown in fig. 1 and 2, wherein the support ribs include lateral support ribs 210 and longitudinal support ribs 220; a plurality of lateral support ribs 210 and longitudinal support ribs 220 are arranged at intervals, and the longitudinal support ribs 220 connect the lateral support ribs 210.
The longitudinal support rib 220 and the lateral support rib 210 are connected to each other to reinforce the overall strength of the mold support 200, thereby preventing the mold support 200 from being damaged or distorted during the punching process. The transverse supporting rib plates 210 and the longitudinal supporting rib plates 220 are arranged at intervals, and meanwhile, production materials can be saved.
As shown in fig. 4, 5 and 6, in order to facilitate the mutual splicing between the support ribs, the longitudinal support ribs 220 and the transverse support ribs 210 are both provided with support snap-in grooves, and the support snap-in grooves on the transverse support ribs 210 are adapted to the support snap-in grooves of the longitudinal support ribs 220.
As shown in fig. 4 to 6, in order to reinforce the connection strength between the lateral support rib 210 and the longitudinal support rib 220 and further reinforce the strength of the entire mold support portion 200, the support catching grooves on the longitudinal support rib 220 include a first long catching groove 221 and a first short catching groove 222, and the first long catching groove 221 and the first short catching groove 222 are arranged at an interval; the support catching grooves on the lateral support ribs 210 include second short catching grooves 212 fitted with the first long catching grooves 221 or/and first long catching grooves 221 fitted with the first short catching grooves 222.
In the present embodiment, the first long latching groove 221 and the second long latching groove 211 have substantially the same groove length, and are both longer than the first short latching groove 222 and the second short latching groove 212. For the lateral support rib plate 210, the length of the support fastening groove affects the strength of the lateral support rib plate 210, so that the support fastening groove on one of the two adjacent lateral support rib plates 210 arranged on the longitudinal support rib plate 220 is the second long fastening groove 211, and the other one is the second short fastening groove 212.
As shown in fig. 5 to 7, preferably, the lateral support rib 210 includes a lateral support portion 213 and a lateral stamped portion 301; the lateral support portion 213 is connected with the longitudinal support rib 220; the die stamping part 300 comprises a transverse stamping part 301 and a die stamping rib plate 310, the die stamping rib plate 310 extends along the longitudinal direction, and the die stamping rib plate 310 and the transverse stamping part 301 are both provided with stamping part clamping grooves 311; the punch catching grooves 311 of the die punch rib 310 and the punch catching grooves 311 of the lateral support rib 210 are fitted to each other.
