Specific embodiment
In order to be more clear the purpose of this utility model, technical solution and its technical effect, below in conjunction with attached drawing and tool
The utility model is described in detail in body embodiment.It should be understood that specific embodiment described in this specification
Just for the sake of explaining the utility model, it is not intended to limit the utility model.
Referring to FIG. 1, the utility model embodiment provides a kind of drawing die, which can be used for manufacturing laundry
Machine rear flange.The drawing die includes upper mold component 10, lower die assembly 20, and upper mold component 10 in the vertical direction may be used
It moves back and forth.It is signified upper and lower herein, it is with the visual angle of operator for reference, i.e., operator faces this mold, specifically,
That is Fig. 1's is upper and lower.Upper mold component 10 includes upper die holder 101, upper clamp plate 102 and cavity plate 103.The lower surface of upper die holder 101
It is connect with the upper surface of upper clamp plate 102, the lower surface of upper clamp plate 102 is provided with upper clamp plate groove 104, upper folder around cavity plate 103
Plate groove 104 matches and is connected thereto with cavity plate 103, and wherein upper clamp plate groove 104 is used to fix the position of cavity plate 103.Under
