Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, a positioning double stripper plate mold with high stretching height disclosed by the utility model comprises a stretching female mold 1, a first lower stripper plate 2, a second lower stripper plate 3 and a lower clamping plate 4 which are arranged in sequence, as shown in fig. 1, a drawing groove 11 is provided on the drawing female die 1, a drawing male 41 sequentially passing through the second lower stripper plate 3 and the first lower stripper plate 2 is provided on the lower clamp plate 4 at a position corresponding to the drawing groove 11, a product 100 is placed on the surface of the drawing male 41, a stripping block 31 and a mandril 32 are fixed on the second lower stripping plate 3, the stripping block 31 is arranged around the outer side surface of the stretching male 41, a clamping groove 21 matched with the stripping block 31 is formed in the first lower stripping plate 2, when the mould does not work, the first lower stripper plate 2 is inserted into the slot 21, and the top rod 32 extends out of the first lower stripper plate.

When the stretching female die 1 and the lower clamp plate 4 perform a die closing action, that is, when the die is in a die closing state, as shown in fig. 2, the stretching female die 1 moves downward to the position of the lower clamp plate 4, the stretching female die 1 contacts the ejector rod 32 first, in the downward moving process, the ejector rod 32 penetrates through the first lower stripper plate 2 to abut against the stretching female die 1 and drive the second lower stripper plate 3 to move downward, at this time, the first lower stripper plate 2 completely abuts against the lower end face of the stretching female die 1, the stripper block 31 is gradually separated from the clamping groove 21, the stretching male die 41 drives the product 100 to gradually extend into the stretching groove 11, and the product 100 is gradually stretched and formed under the matching of the stretching groove 11 and the stretching male die 41. Further, seted up on tensile die 1 with the communicating spout 12 of tensile recess 11, spout 12 is located tensile recess 11's top, sliding connection takes off pole 13 in the spout 12, interior taking off pole 13 stretch into to tensile recess 11 is interior and is located tensile public 41's top tensile public 41 begins to drive product 100 and enters into when in the draw-in groove 21, interior taking off pole 13 supports and leans on in the product 100 surface, along with the lapse of tensile die 1, tensile public 41 shifts up gradually, interior taking off pole 13 is continuously pressing product 100 slide in the spout 12, plays the effect of location product 100, avoids the aversion of product 100 to influence stretch forming's effect.

The stretching female die 1 continues to move downwards until the stretching female die 1 and the lower clamping plate 4 achieve a die closing state, as shown in fig. 3, the stretching male die 41 completely enters the stretching female die 1, and the product 100 completes the stretching forming operation in the stretching female die. The lower extreme of lower plate 4 still is equipped with lower bolster 5 that is used for the buffering, because when the mould state is closed, tensile die 1 gives the pressure of lower plate 4 is great, lower bolster 5 can further avoid causing the loss of the table surface of whole mould.

After the product 100 is stretched and formed, the stretching female die 1 moves upwards to be matched with the lower clamping plate 4 again and enters a die opening state again, as shown in fig. 4, the drawing die 1 moves upward, the ejector pin 32 and the first lower stripper plate 2 are gradually separated from the drawing die 1, the first lower stripper plate 2 and the second lower stripper plate 3 are gradually attached to each other, at which time the stretching male 41 starts to separate from the stretching groove 11 with the product 100, when the first lower stripper plate 2 and the second lower stripper plate 3 are completely attached, the stripper block 31 is inserted into the draw groove, and the lower end of the product 100 abuts against the stripper block 31 and is separated from the draw pin 41 as the stripper block 31 moves upward, namely, the product 100 is no longer in contact with the surface of the stretching male 41, so that the stripping of the product 100 is completed, and the operator can conveniently recover the stretched product 100. Furthermore, the stripping block 31 is in a ring shape with a narrow top and a wide bottom, the stretching male member 41 penetrates out of the middle of the stripping block 31, the contact area between the product 100 and the stripping block 31 is increased, the product 100 is easier to be stripped, the clamping groove 21 is matched with the stripping block 31 in a shape with a narrow top and a wide bottom, and the stripping block 31 is prevented from continuously extending out of the clamping groove 21 when the second lower stripping plate 3 moves upwards to be in contact with the first lower stripping plate 2, so that the stripping block 31 is limited. The thickness of the narrow portion of the stripper block 31 is greater than the thickness of the product 100, ensuring that the stripper block 31 can completely contact the product 100 and smoothly eject the product 100.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
