Detailed description of the invention

Below in conjunction with the accompanying drawings a kind of preferred implementation of the present invention is described in detail.

As it is shown in figure 1, described composite die includes compound upper mold 10 and the compound lower mold 20 arranged up and down, compound upper mold and compound lower mold are both placed on hydraulic machine, and compound upper mold and compound lower mold have been provided with davit 50, it is simple to install.Composite die is used for beading and bending fork truck exterior panel 60, and the molding of this fork truck exterior panel is with reference to Fig. 5.

As in figure 2 it is shown, described compound upper mold 10 includes baffle plate 11, upper mold insert seat the 12, first bending insert 13, the recessed insert of beading 14 and the second bending insert 15.Described upper mold insert seat 12 is fixed on the bottom surface of baffle plate 11, described first bending insert 13, the recessed insert of beading 14 and the second bending insert 15 are successively set on the bottom surface of upper mold insert seat 12, wherein the first bending insert 13 is for the side of 90 degree of bending fork truck exterior panels, second bending insert 14 is for the opposite side of multi-angle bending fork truck exterior panel, and the recessed insert of described beading 14 is used for suppressing reinforcement.

As it is shown on figure 3, described compound lower mold 20 includes 21, two lower mold insert seat 22 and Tuo Liao beading mechanisms 30 of lower mould bottom plate.Described lower mold insert seat uses riser structure, and the inner side of two lower mold insert seats is provided with wear-resisting insert 23, and this wear-resisting insert is detachable, is convenient for changing.

The two ends of the lower mold insert seat on right side are provided with the end location-plate 24 for spacing compound upper mold, wherein the front end of lower mold insert seat arranges end limited block 25, the outside of this lower mold insert seat is provided with side location-plate 26, and described end limited block and side location-plate are used for positioning fork truck exterior panel.Matched moulds for convenience, is provided with guide plate 40 at the corner end of described upper mold insert seat 12 and lower mold insert seat 22.

Described Tuo Liao beading mechanism 30 is placed between two lower mold insert seats 22, and this Tuo Liao beading mechanism is suitable with described first bending insert 13, the recessed insert of beading 14 and the second bending insert 15, and fork truck exterior panel is carried out beading and bending and molding.
