But because the mould is fixedly connected with the mould bracket, the central height of the mould is not easy to adjust.
The utility model has the following contents:
the utility model aims at overcoming prior art not enough, providing a tensile mould of split type copper pipe of center height-adjustable, it can be under the condition of not demolising the mould body through the central height of the adjustable mould body of altitude mixture control piece of changing different height specifications, and the regulative mode is simple, convenient, swift.
The utility model provides a technical problem's scheme is:
a split type copper pipe stretching die with an adjustable center height comprises a die base and a die body which are arranged in a split mode, wherein the die body comprises an upper die body and a lower die body which are fixedly connected through bolts, and a die core is clamped between the upper die body and the lower die body; four guide posts which are uniformly distributed on the circumference are fixed on the bottom surface of the lower die body, and each guide post is inserted in a corresponding guide hole on the die base; a radially raised quadrangular prism is formed in the middle of the guide post, a U-shaped height adjusting block is sleeved on the quadrangular prism, and the height adjusting block is clamped between the lower bottom surface of the lower die body and the upper bottom surface of the die base; and the periphery of the lower die body is respectively sleeved with a screw, and the lower end of the screw is in threaded connection with the die base.
The height specification of the height adjusting block has multiple kinds, and the height of the lower die body is adjusted by replacing the height adjusting blocks with different height specifications.
The height adjusting blocks of each height specification are not less than four.
The height adjusting block is characterized in that a detachable barrier strip is fixed on the end face of the opening of the height adjusting block through screws, and the quadrangular prism is arranged in a rectangular frame formed by the barrier strip and the height adjusting block in a surrounding mode.
And the screw is sleeved with a pressure spring, and the pressure spring is clamped between the lower bottom surface of the lower die body and the upper bottom surface of the die base.
The height of the quadrangular prism is smaller than that of the height adjusting block.
Two handles which are arranged left and right are fixed on the upper side wall of the upper die body.
The utility model discloses an outstanding effect is:
compared with the prior art, the center height of the die body can be adjusted by replacing the height adjusting blocks with different height specifications under the condition that the die body is not detached, and the adjusting mode is simple, convenient and quick.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a front view of the present invention;
FIG. 3 is a cross-sectional view taken along A-A of FIG. 2;
FIG. 4 is a cross-sectional view taken along line B-B of FIG. 3;
fig. 5 is a cross-sectional view taken along line C-C of fig. 4.
The specific implementation mode is as follows:
in an embodiment, as shown in fig. 1 to 5, a split copper pipe stretching mold with an adjustable center height includes a mold base 1 and a mold body 2, which are separately arranged, the mold body 2 includes an upper mold body 21 and a lower mold body 22 fixedly connected by bolts, and a mold core 23 is clamped between the upper mold body 21 and the lower mold body 22; four guide posts 24 which are uniformly distributed on the circumference are fixed on the bottom surface of the lower die body 22, and each guide post 24 is inserted in a corresponding guide hole 11 on the die base 1; a radially convex quadrangular prism 241 is formed in the middle of the guide column 24, a U-shaped height adjusting block 25 is sleeved on the quadrangular prism 241, and the height adjusting block 25 is clamped between the lower bottom surface of the lower die body 22 and the upper bottom surface of the die base 1; the periphery of the lower die body 22 is sleeved with a screw 26 respectively, and the lower end of the screw 26 is screwed on the die base 1.
Furthermore, the height specification of the height adjusting block 25 is various, and the height of the lower mold body 22 can be adjusted by replacing the height adjusting block 25 with different height specifications.
Further, the height adjusting blocks 25 of each height specification are not smaller than four.
Furthermore, a detachable barrier strip 27 is fixed on the end surface of the opening of the height adjusting block 25 through screws, and the quadrangular prism 241 is arranged in a rectangular frame enclosed by the barrier strip 27 and the height adjusting block 25.
Furthermore, a compression spring 28 is sleeved on the screw 26, and the compression spring 28 is clamped between the lower bottom surface of the lower die body 22 and the upper bottom surface of the die base 1.
Further, the height of the quadrangular prism 241 is smaller than that of the height adjusting block 25.
