The new core isostatic cool pressing wet bag method directional compression mould of the utility model; Comprise tubular body, mandrel, upper end cover and bottom end cover; Said upper end cover is installed in the upper end oral area of main body, and said bottom end cover is installed in the lower end oral area of main body, and the bottom of said upper end cover and the top of bottom end cover are provided with blind hole; The top of said mandrel is fixed in the blind hole of said upper end cover bottom, and the bottom of said mandrel is fixed in the blind hole at said bottom end cover top; Said external side of main body is provided with the stay pipe that has through hole.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, said upper end cover and bottom end cover are " protruding " font.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, the thickness of said stay pipe is 3mm-5mm, and the top of said stay pipe contacts with upper end cover, the bottom of said stay pipe contacts with bottom end cover.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, said through hole is a plurality of.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model; The diameter of bore of said stay pipe is less than the overall diameter of gum cover; Comprise first semicanal and second semicanal; Said first semicanal and second semicanal all are trapped among said external side of main body, and the arranged outside of said first semicanal and second semicanal has clip.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, said main body is a gum cover.
Compared with prior art the beneficial effect of the utility model is: be provided with blind hole in the bottom of upper end cover and the top of bottom end cover, the top of mandrel is fixed in the blind hole of said upper end cover bottom, and the bottom of mandrel is fixed in the blind hole at said bottom end cover top; External side of main body is provided with the stay pipe that has through hole, like this, can be according to hole site in the workpiece through the better positioning core axle of blind hole, thus scrappage reduced, and play the effect of protective core axle through the support of stay pipe, increased production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; The new core isostatic cool pressing wet bag method directional compression mould of the utility model comprises tubular body 1, mandrel 2, upper end cover 3 and bottom end cover 4, and upper end cover is installed in the upper end oral area of main body; Bottom end cover is installed in the lower end oral area of main body; The bottom of upper end cover and the top of bottom end cover are provided with blind hole, and the top of mandrel is fixed in the blind hole of upper end cover bottom, and the bottom of mandrel is fixed in the blind hole at bottom end cover top; External side of main body is provided with the stay pipe 5 that has through hole 6; Like this, can pass through the better positioning core axle of blind hole according to the position of workpiece endoporus, thereby reduce scrappage, and play the effect of protecting mandrel, increase production efficiency through stay pipe.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, upper end cover and bottom end cover are " protruding " font, like this, can better upper end cover and bottom end cover be fixed on the main body.
The new core isostatic cool pressing wet bag method directional compression mould of the utility model, the thickness of stay pipe is 3mm-5mm, and the top of stay pipe contacts with upper end cover, the bottom of stay pipe contacts with bottom end cover; Like this, can effectively reduce the diameter of upper end cover and lower end, each plastic many products form batch machining, have improved production efficiency, have solved with the isostatic cool pressing dry bag method and need use the special equipment and the drawback of single inefficiency of moulding at every turn.
