Description

A kind of upwards shaping mould

Technical field

The utility model relates to a kind of stamping parts of automobile shaping mould, particularly adopts the wedge structure mode to make progress the upwards shaping mould of shaping of stamping parts of automobile.

Background technology

At present, being used for the make progress mould of shaping of stamping parts of automobile, generally is the mould structure that adopts counterdie design activity eccentric swage, drives the descending upwards purpose of shaping that realizes of eccentric swage by patrix.The complex structure of the upwards shaping mould of this kind structure, the mould volume is big, cost is higher and assembly difficulty is big.

The utility model content

The purpose of this utility model provides a kind of simple in structure, with low cost, and assembling is easy to the stamping parts of automobile shaping mould that makes progress.

Upwards shaping mould described in the utility model, comprise upper bolster, die shoe and be installed in the guide pillars and bushes that is slidingly matched in the die holder up and down, cross sliding clock is installed on die shoe, counterdie is inserted and the backhaul driver, cross sliding clock can move as transverse horizontal on die shoe, have on it one to upper left side plane inclined and one to the upper right side plane inclined, counterdie is inserted and is positioned at the cross sliding clock left side, the backhaul driver is positioned at the cross sliding clock below, gives cross sliding clock active force to the right; The right side of inserting at counterdie is equipped with die socket, die socket can be for vertical movement on counterdie is inserted, the die socket lower end has one to the lower right plane inclined, fitting of this plane and cross sliding clock to the upper left side plane inclined, right side, die socket upper end is fixed with correcting die, underside shape after the shaping position shaping of correcting die upper left corner upper surface shape and shaping part is consistent, when the matched moulds state, the counterdie upper surface of inserting is consistent with the underside shape after correcting die upper left corner upper surface is connected formed shape and the shaping of shaping part.

Briquetting, eccentric swage, cushion block and nitrogen spring are installed on upper bolster, have a square to left down plane inclined on the briquetting, when the matched moulds state, the fitting of this plane and cross sliding clock to the upper right side plane inclined; Eccentric swage be positioned at counterdie insert and correcting die directly over, being slidingly matched with upper bolster also can be mobile vertically along upper bolster, its lower surface shape is consistent with upper surface shape after the shaping of shaping part, nitrogen spring is between upper bolster and eccentric swage, it gives eccentric swage active force vertically downward, and cushion block is between upper bolster and eccentric swage.

Be mounted with cushion pad and backhaul limited block on die shoe, cushion pad is positioned at the right side of cross sliding clock, plays the spacing of cross sliding clock and buffering effect.The backhaul limited block is positioned at the left side of cross sliding clock and the below of die socket, too produces unsafe factor to left movement to prevent the water smooth block.

When mould is in open mode (die sinking), cross sliding clock moves right under the effect of backhaul driver, thereby die socket is inserted at gravity effect lower edge counterdie to move down, move right to extreme position until cross sliding clock, in this process, cross sliding clock keep to be fitted to the lower right plane inclined with die socket all the time to the upper left side plane inclined, will intend the shaping part this moment and be placed on the upper surface that counterdie inserts.

When mould moved downward, guide pillar contacted guiding earlier with guide pin bushing, to guarantee the closing precision of upper and lower mould.Eccentric swage is pressed on counterdie inserts will intending the shaping part under the effect of nitrogen spring then, afterwards, the square to left down plane inclined of briquetting contacts to the upper right side plane inclined with cross sliding clock, and promote cross sliding clock to left movement, cross sliding clock promotes die socket again and inserts along counterdie and move upward, the final upwards shaping that realizes intending the shaping part.

The effect of cushion block is the position of restriction eccentric swage, with the purpose that guarantees that correcting die contacts with the eccentric swage rigidity.

Upwards shaping mould described in the utility model is simple in structure, with low cost and assembling is easy.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the upwards structural representation of shaping mould when closure state (mold closing) described in the utility model;

Fig. 2 is the structural representation of shaping mould when open mode (die sinking) that should make progress;

Fig. 3 is the cross-sectional view of shaping part before and after shaping, and wherein piece number 3 is represented the shape that shapings are preceding, the shape after the piece number 21 expression shapings.

The specific embodiment

As depicted in figs. 1 and 2, upwards shaping mould comprises upper bolster 1, die shoe 11 and is installed in the guide pin bushing 14 in the upper bolster 1 and is installed in guide pillar 12 in the die shoe 11, and guide pin bushing 14 and guide pillar 12 are slidingly matched.Cross sliding clock 9, counterdie are installed on die shoe 11 insert 6 and backhaul driver 10, cross sliding clock 9 can move as transverse horizontal on die shoe 11, have on it one to upper left side plane inclined 19 and one to upper right side plane inclined 20; Counterdie is inserted and 6 is positioned at cross sliding clock 9 left sides, and backhaul driver 10 is positioned at cross sliding clock 9 belows, gives cross sliding clock 9 active force to the right.On insert 6 right side of counterdie die socket 7 is installed, die socket 7 can be inserted for vertical movement on 6 at counterdie, die socket 7 lower ends have one to lower right plane inclined 17, fitting of this plane and cross sliding clock 9 to upper left side plane inclined 19, right side, die socket 7 upper end is fixed with correcting die 2, and the underside shape after the shaping position shaping of correcting die 2 upper left corner upper surface shapes and shaping part 3 is consistent.When the matched moulds state, counterdie 6 upper surfaces of inserting are consistent with the underside shape after correcting die 2 upper left corner upper surfaces are connected formed shape and 3 shapings of shaping part.Be mounted with cushion pad 13 and backhaul limited block 8 on die shoe 11, cushion pad 13 is positioned at the right side of cross sliding clock 9, and backhaul limited block 8 is positioned at the left side of cross sliding clock 9 and the below of die socket 7.

Briquetting 15, eccentric swage 5, cushion block 16 and nitrogen spring 4 are installed on upper bolster 1, have a square to left down plane inclined 18 on the briquetting 15, when the matched moulds state, the fitting of this plane and cross sliding clock 9 to upper right side plane inclined 20.Eccentric swage 5 be positioned at counterdie insert 6 and correcting die 2 directly over, be slidingly matched with upper bolster 1 and can move vertically along upper bolster 1, its lower surface shape is consistent with upper surface shape after 3 shapings of shaping part.Nitrogen spring 4 is between upper bolster 1 and eccentric swage 5, and it gives eccentric swage 5 active force vertically downward, and cushion block 16 is between upper bolster 1 and eccentric swage 5.

As shown in Figure 1, when mould is in die opening state, cross sliding clock 9 is in the limit on the right-right-hand limit position on die shoe 11, die socket 7 is in the limit inferior position on die shoe 11, be placed on counterdie and insert on 6 the upper surface intending shaping part 3, when mould moves downward, guide pillar 12 contacts guiding earlier with guide pin bushing 14, eccentric swage 5 is pressed in counterdie and inserts on 6 will intending shaping part 3 under the effect of nitrogen spring 4 then, afterwards, briquetting 15 promotes cross sliding clock 9 to left movement, and cross sliding clock 9 promotes die socket 7 again and moves upward, until finishing matched moulds, thereby realize intending the upwards shaping of shaping part 3.
