Embodiment 1

[0020] The overturning mold of the present embodiment comprises an upper mold base 10, a punch insert 9, a die template, and a lower die base 1, and the punch insert 9 is fixed on the punch body of the upper die base 10, and the die template and the lower die base The mold base 1 is connected, the die template includes a bottom plate 11 and two side plates 13, the bottom plate 11 is set between the side plates 13, the two side plates 13 and the bottom plate 11 are arranged on the same horizontal line, and the side plate 13 and the bottom plate 11 are movable connect. The movable connection between the side plate 13 and the bottom plate 11 is configured as a hinged connection. The hinges 4 and 6 are arranged at both ends of the side plate 13 . On the lower die base 1, at the contact of the side plate 13 and the lower die base 1 cavity, rollers 14 are set and the rollers 14 are fixed on the lower die base by the mounting bracket 2. Roller 14 is provided with three groups at le...

Embodiment 2

[0025] The difference between the overturning mold of this embodiment and Embodiment 1 is that the hinges of this embodiment are arranged in the middle of the bottom plate in two groups, and the rollers are arranged in two groups.

Embodiment 3

[0027] The difference between this embodiment and Embodiment 1 is that the hinges of this embodiment are provided at both ends and in the middle, one set is set in the middle, one set is set at both ends, and one set of rollers is set in the middle of the side plate.

[0028] The flip-type mold structure of the present invention reduces the load of the mold when the sheet is formed, and reduces the friction between the mold and the sheet, so that no stretch marks will be formed on the outer surface of the formed part, which improves the surface quality of the formed part and prolongs the The service life of the mold is greatly reduced.

Abstract

The invention relates to a mould, in particular to an overturning type mould. The invention provides the overturning type mould which is capable of reducing the friction between board material and the mould since a side plate of a concave die of the mould can be overturned in the process of shaping a workpiece. The overturning type mould comprises an upper die base, a concave die insert, a concave die plate and a lower die base, wherein the concave die insert is fixed on the upper die base; the concave die plate is connected with the lower die base; the concave die plate comprises a bottom plate and two side plates; the bottom plate is arranged between the side plates; the two side plates and the bottom plate are arranged on the same horizontal line; the side plates are connected with the bottom plate in a movable way; and at least one group of roller wheels are arranged at the contact part between sides plates of the concave die plate and a concave die cavity of the lower die base on the lower die base, and are fixed on the lower die base by mounting brackets. As the roller wheels are arranged, the resistance for overturning the side plates can be reduced, and rotation support is provided for the overturning of the side plates.

Description

[0001] technical field [0002] The invention relates to a mold, in particular to an overturning mold. Background technique [0003] In the bending and pressing of truck longitudinal beams and beams, a convex and concave mold is used to press the upper mold into the concave mold on the punching machine for bending and forming. The tensile strength of the formed metal is greater than 510Mpa, and the thickness is 4~8mm. Sometimes, double-layer plates are used to form at the same time, and the forming thickness reaches 16mm. The traditional mold mainly includes the upper mold base, the punch insert, the die insert, the lower mold base and the pallet, the punch insert is installed on the punch body of the upper die base, and the die insert is installed both sides of the mold cavity. The supporting plate is connected with the ejector rod of the press and can move up and down along the die cavity. When the traditional mold is used for forming, the mold bears a large load, and s...
