Embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate embodiment of the present utility model.
With reference to shown in Fig. 1 to Fig. 4, diel includes upper mould 1, lower mould 2, and upper mould 1 is provided with the upper mould relative with lower mould 2
Downward mould 2, which stretches out, in core 11, upper mold core 11 is provided with staking punch 12.
The overall support material structure bag being applied in the branched diel of multiple row in one preferred embodiment of the utility model
Include the support material block 3 and resetting-mechanism 4 being arranged on lower mould 2.Support material block 3 and upper mold core 11 is relative, and can be the of mould under stretching 2
Moved between the second place B that one position A and downward mould 2 are retracted, resetting-mechanism 4 provides one and keeps support material block 3 at first
Put A elastic force.
Further, with reference to shown in Fig. 5, shape on four support material units 31, each support material unit 31 is distributed with support material block 3
Into there is two core rod holes 311 relative with upper mould 1.Support material wall 312, support material wall 312 and punching are formed between two core rod holes 311
Pressure head 12 is just right, before the punching, and support material wall 312 can treat stamping parts 5 and support.
Lower mold core 21 is equipped with core rod hole 311 respectively, when upper mould 1 is punched down, lower mold core 21, support material wall 312, punching
The collective effect of pressure head 12 is treated stamping parts 5 and is molded.Stamping parts 5 is treated when upper mould 1 is close to lower mould 2 and carries out punch forming, staking punch
12 impact support material walls 312, support material block 3 is compressed to second place B by first position A.
When support material block 3 is in second place B, the corresponding lower mold core 21 of each support material unit 31 and the support material formation of wall 312 are supplied
The concave inward structure that staking punch 12 is inserted, 12 pairs of upper parts to be punched 5 between mould 1, lower mould 2 of concave inward structure and staking punch are molded, will
Part 5 to be punched strikes out specific shape.After upper mould 1 is away from the movement of lower mould 2, in the presence of resetting-mechanism 4, support material block 3
First position A is reset to, the part to be punched 5 after shaping is ejected upwards, a molding cycle of part 5 to be punched is completed.Wait to rush
Casting die 5, which is completed after shaping, to be terminal shell fragment, or other hardware stamping parts.
Four support material units 31 arrange arrangement on support material block 3 by two, per two support material units 31 of column distribution.In other implementations
In example, support material unit 31 or two or other multiple quantity, support material unit 31 is in support material block 3 and the upper opposite side of mould 1
Laterally, arranged at least one direction in longitudinal direction.
Multiple support material units 31 are set to work simultaneously on one support material block 3 so that the outer deformation of support material block 3 is big, and structure is strong
Degree gets a promotion, and also makes stress more uniform balance, it is to avoid material strip stress raisers, makes feeding more steady, lifting
Yields.Meanwhile, the distribution of force of resetting-mechanism 4 is also easy to arrangement, pressure-plate-force enhancing, allows the stable molding of part 5 to be punched.Simultaneously
The overall stress of material strip of multiple parts is molded, the drawing velocity of mould can be effectively improved.
Size, the profile of support material wall 312, lower mold core 21 and staking punch 12 can be set according to specific product.In order to prevent
Part 5 to be punched is scratched in forming process by lower mold core 21, and lower mold core 21 is formed with circular arc mistake with the corresponding edge of support material wall 312
Cross, part 5 to be punched can be slided into deformation process in concave inward structure.
In order to prevent the lower mould 2 of support material block 3 abjection, it is respectively equipped with the two opposite sides of support material block 3 in limiting stand 32, lower mould 2
Provided with it is corresponding with limiting stand 32 keep out keep out platform.Further, jam plate 22, lock are provided with lower mould 2 side relative with upper mould 1
Plate 22 and the mobile space for keeping out restriction limiting stand 32 between platform, to limit the height that support material block 3 stretches out lower mould 2.
In order to ensure that the steering that lower mold core 21 loads when in core rod hole 311 every time will not malfunction, set on each core rod hole 311
Have and position the positioning corner cut 3111 turned to for lower mold core 21, lower mold core 21 is provided with corresponding with positioning corner cut 3111 on one side respectively
Positioning tangent plane.When inserting lower mold core 21, make the positioning tangent plane corresponding with positioning corner cut 3111 position it is ensured that when inserting
Steering will not malfunction.
Further, since the shape of each 31 corresponding two correspondence shapings of lower mold core 21 of support material unit may be different, often
The position of the orientation angle in two core rod holes 311 of one support material unit 31 is different, allows two lower mold cores 21 of each support material unit 31
It will not also malfunction when mounted.
Preferably, resetting-mechanism 4 includes four groups of ejecting units, one support material unit 31 of every group of ejecting unit correspondence, to support
Expect that block 3 uniformly exerts a force.Certainly, in other embodiments, the quantity of ejecting unit can be adjusted according to the quantity of support material unit 31
And position.
Ejecting unit includes ejector pin 41 and return unit 42, and ejector pin 41 is located at support material block 3 side opposite with upper mould 1.Ejector pin
41 one end and support material block 3 offset cooperations, and return unit 42 is provided to ejector pin 41 keeps support to expect elastic force of the block 3 in first position A.
Support material block 3 is pressed onto after the B of the second place by upper mould 1, in the presence of return unit 42, and support material block 3 is upspring to first position A, allowed
Support material block 3 is carrying out the shaping in next cycle.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
