An upper base plate is installed in a cavity of the upper die base, and an upper die base positioning sleeve is installed and connected with the upper base plate.

And a lower cushion plate is arranged in the cavity of the lower die base, and the lower die base positioning sleeve is connected with the lower cushion plate in an installing way.

And a transition base plate is also arranged between the lower base plate and the lower die base positioning sleeve and is respectively connected with the lower base plate and the lower die base positioning sleeve in an installing way.

And the bottom surface of the lower die base is provided with an ejector rod, and the ejector rod extends to the cavity of the lower die base from the lower backing plate and the transition backing plate.

The through holes of the upper die holder positioning sleeve and the lower die holder positioning sleeve are the same in shape and are circular or polygonal.

The size of the upper die base positioning sleeve is the same as that of the lower die base positioning sleeve, the upper die base positioning sleeve is detachably and tightly matched with the upper die base, and the lower die base positioning sleeve is detachably and tightly matched with the lower die base.

The utility model discloses a set up upper die base position sleeve and die holder position sleeve, through the size that sets up different through-holes to under the condition that need not change the die holder, just can realize the processing of the product of different size and dimension, the suitability is more extensive.

Fig. 1 is a schematic view of the exploded cross-section structure of the present invention.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in the accompanying drawing 1, the utility model discloses a general mould, including upper die base 1 and die holder 2, all be equipped with the die cavity in upper die base 1 and the die holder 2, be equipped with band-pass hole's upper die base position sleeve 5 in the die cavity of upper die base, be equipped with band-pass hole's die holder position sleeve 8 in the die cavity of die holder 2, install location core 6 on the upper die base 1, be equipped with guide pin bushing 3 on the upper die base 1, be equipped with guide pillar 4 on the die holder 2, guide pillar 4 cartridge is gone into in guide pin bushing 3 during upper die base 1 and the pressfitting of die holder 2, and die holder position sleeve 8 is just facing upper die base position sleeve 5. The guide pillar and the guide sleeve are matched, so that the upper die base and the lower die base are more convenient to assemble, directionality is achieved, installation errors are avoided, and installation accuracy is improved. The through holes of the upper die base positioning sleeve and the lower die base positioning sleeve are usually circular in shape, and circular modules can be processed. Of course, if necessary, the shape may be polygonal or other shapes. The size of the upper die base positioning sleeve is the same as that of the lower die base positioning sleeve, and the shape of the through hole is kept the same.

The upper die base locating sleeve and the lower die base locating sleeve are respectively installed in a detachable mode, for example, the upper die base locating sleeve and the lower die base locating sleeve can be taken out conveniently for tight fit, so that different types are replaced, the size and the shape of different through holes can be used for machining different products, the die base locating sleeve and the lower die base locating sleeve are suitable for products with different sizes, the whole die base does not need to be replaced, and the operation efficiency is improved.

An upper base plate 7 is installed in a cavity of the upper die holder 1, and an upper die holder positioning sleeve 5 is installed and connected with the upper base plate 7.

And a lower backing plate 9 is arranged in the cavity of the lower die holder 2, and a lower die holder positioning sleeve 8 is connected with the lower backing plate 9 in an installing way.
