In order to support the plate member and prevent the plate member from collapsing during the forming process, as shown in fig. 1, the present invention provides a hot press forming die. This hot stamping forming die includes: the upper die, the lower die 1 and the auxiliary supporting component.
The upper die can move relative to the lower die 1 to be close to or far away from the lower die 1, and the plate is placed on the lower die 1; the auxiliary stay subassembly sets up on lower mould 1, and auxiliary stay subassembly's one end and sheet material butt, auxiliary stay subassembly can be along with last mould extrusion sheet material relative lower mould 1 progressively retracts in order to guarantee the sheet material shaping.
The auxiliary supporting assembly is arranged to support the plate, so that the plate is prevented from collapsing in the hot stamping forming process of the plate. Specifically, in this embodiment, the auxiliary supporting component is provided with a set of, in other embodiments, also can set up the multiunit according to actual needs to promote the support effect to the sheet material, further guarantee hot stamping forming's effect. However, since the auxiliary support member is provided on the lower mold 1, the auxiliary support member needs to be designed according to the actual situation.
Furtherly, supplementary supporting component includes elastic component 2 and bracing piece 3, has seted up first mounting groove on the lower mould 1, and bracing piece 3 sets up in first mounting groove, and one end relative first mounting groove stretch out with the sheet material butt, and elastic component 2 sets up in first mounting groove, the tank bottom butt of one end and first mounting groove, the other end and 3 butts of bracing piece. In the process of carrying out hot stamping forming on the plate material, the support rod 3 is along with the upper die pressing plate material, the support rod 3 is along with compressing the elastic part 2, smooth forming of the plate material is guaranteed, after the plate material is formed, the manufactured part is taken out, and the support rod 3 automatically bounces under the action of the elastic part 2. Further, in the present embodiment, the elastic member 2 is a compression spring.
Further, offer the second mounting groove that is linked together with first mounting groove on the lower mould 1, the second mounting groove is located the upper end of first mounting groove, and the diameter of second mounting groove is less than the diameter of first mounting groove, and bracing piece 3 includes interconnect's guide part 32 and supporting part 31, and guide part 32 is located first mounting groove, and supporting part 31 wears to locate in the second mounting groove, and stretches out relative second mounting groove.
