A kind of punch-forming mold described in the utility model, comprise base plate and be positioned at the top board above base plate, the upper plane of described base plate is fixed with die, the upper plane of described base plate is vertically fixed with at least two slide bars through described top board, described top board can slide up and down along described slide bar, the lower plane of described top board is fixed with punch, described punch is provided with punch operate portions, the upper plane of described die is provided with the groove for placing sheet material to be processed, the bottom of described groove is provided with the die operate portions corresponding with described punch operate portions, the bottom of described groove is provided with electric hot plate, the upper plane of described electric hot plate is concordant with the upper end of described die operate portions, a sidewall of described die is provided with the wire hole allowing the power line of described electric hot plate pass through, described die is provided with the strip through-hole running through described die from left to right, the lower wall of described strip through-hole and the upper co-planar of described electric hot plate, and described strip through-hole width is in the longitudinal direction greater than described groove width in the longitudinal direction, be provided with the plastic sheeting through described strip through-hole in described strip through-hole, described plastic sheeting width is in the longitudinal direction greater than described groove width in the longitudinal direction, the left side of described die or right side are provided with the retracting device for pulling described plastic sheeting.
Further, described punch comprises pedestal and described punch operate portions, and the bottom of described pedestal is corresponding with described groove to be arranged, and when not placing sheet material to be processed in described groove, the bottom of described pedestal can be stretched in described groove.
Further, the upper end of described die operate portions protrudes from the bottom surface of described groove, the lateral wall of described electric hot plate and the sidewall contact of described groove, and the middle part of described electric hot plate is provided with the hole corresponding with the upper end of described die operate portions.
The utility model adopts plastic sheeting to replace the lubricant used in traditional releasing process, the cost of plastic sheeting is extremely low, plastic sheeting is between sheet material to be processed and die operate portions, reduce the frictional force between plate stretch face to be processed and die operate portions by the slip of plastic sheeting, thus reach the generation preventing the bad phenomenon such as part generation is wrinkling, cracking, uneven distribution, surface scratch; This lubrication system has the advantage of the quality that stripping result is good, cost is low and improve part; Utilize strip through-hole to carry out spacing to plastic sheeting, and utilize retracting device to pull plastic sheeting, to prevent plastic sheeting fold, make operating personnel's handled easily; Arrange electric hot plate, the plastic sheeting treated in process below machining sheet heats, and to make plastic sheeting soften, more easily deforms and stretches, and avoids the phenomenon that fracture and opening occur plastic sheeting.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of punch-forming mold as depicted in figs. 1 and 2, the top board 3 comprising base plate 1 and be positioned at above base plate 1, the upper plane of base plate 1 is fixed with die 2, the upper plane of base plate 1 is vertically fixed with four slide bars 5 through top board 3, top board 3 can slide up and down along slide bar 5, the lower plane of top board 3 is fixed with punch 4, punch 4 is provided with punch operate portions 11, as shown in Figure 3 and Figure 4, the upper plane of die 2 is provided with the groove 13 for placing sheet material 8 to be processed, the bottom of groove 13 is provided with the die operate portions 12 corresponding with punch operate portions 11, the bottom of groove 13 is provided with electric hot plate 10, the upper plane of electric hot plate 10 is concordant with the upper end of die operate portions 12, a sidewall of die 2 is provided with the wire hole 9 allowing the power line of electric hot plate 10 pass through, die 2 is provided with the strip through-hole 7 running through die 2 from left to right, the lower wall of strip through-hole 7 and the upper co-planar of electric hot plate 10, and strip through-hole 7 width is in the longitudinal direction greater than groove 13 width in the longitudinal direction, be provided with the plastic sheeting 6 through strip through-hole 7 in strip through-hole 7, plastic sheeting 6 width is in the longitudinal direction greater than groove 13 width in the longitudinal direction, the left side of die 2 or right side are provided with the retracting device (not shown in FIG.) for pulling plastic sheeting 6.Because plastic sheeting 6 width is in the longitudinal direction greater than groove 13 width in the longitudinal direction, in process, drive plastic sheeting 6 to move by surplus on plastic sheeting 6 width, avoid plastic sheeting 6 to break.Adopt above-mentioned Mould Machining piece surface out to clean, can not postpartum because making the greasy dirt with lubricator brought, and part punching steady quality.
