As is well known, a compressor partition plate is one of parts of a compressor, in order to meet working requirements, inclined holes need to be machined in part of the compressor partition plate, and a forming die cannot realize the compressor partition plate with the inclined holes in the integrally formed position, so that after the compressor partition plate is formed through compression molding, the compressor partition plate needs to be additionally machined to machine the inclined holes.

To this end, some embodiments of the present invention provide a spacer die, particularly as shown in FIGS. 1-7 of the drawings.

Referring to fig. 1, in some embodiments, a separator die 100 is used for compression molding of a compressor separator 200, after compression molding of the compressor separator 200, an inclined hole 211 is machined, the separator die 100 includes a lower die 110, an upper die 120 and a female die 130, a first protrusion 111 is formed on a side wall of the lower die 110, and the first protrusion 111 extends to an upper end face of the lower die 110 along an axial direction of the lower die 110; a second protrusion 121 is formed on the side wall of the upper die 120, the second protrusion 121 extends to the lower end surface of the upper die 120 along the axial direction of the upper die 120, and a boss 122 is arranged on the lower end surface of the upper die 120; the female die 130 surrounds the lower die 110 and the upper die 120; the position of the second protrusion 121 corresponds to the position of the first protrusion 111, so that when the compressor partition plate 200 is molded by pressing, the sidewall of the molded compressor partition plate 200 has a third protrusion 210, the third protrusion 210 extends to the upper end surface and the lower end surface of the compressor partition plate 200 along the axial direction of the compressor partition plate 200, and the inclined hole 211 is at least partially disposed in the third protrusion 210; the position of the boss 122 corresponds to the position of the compressor partition board 200 where the inclined hole 211 needs to be processed, so that when the compression molding is performed, a recess is formed at the position of the molded compressor partition board 200 where the inclined hole 211 needs to be processed.

It can be understood that when the metal powder is put into the separator mold 100 and pressed during the compression molding, the raw material loss is small, and the manufactured compressor separator 200 has low internal stress and stable mechanical properties.

It can be understood that the position of the boss 122 corresponds to the position of the compressor partition board 200 where the inclined hole 211 needs to be processed, so that the density of the part of the compressor partition board 200 where the inclined hole 211 needs to be processed is higher than that of other parts due to the boss 122 during the compression molding, so that the inclined hole 211 is not easily broken when the inclined hole 211 is processed.

It should be noted that the first protrusion 111 and the second protrusion 121 have the same cross-sectional shape, so that the molded compressor partition plate 200 is symmetrical up and down.

It should be noted that, according to practical situations, the cross-sectional shapes of the first protrusion 111 and the second protrusion 121 may also be different, and are not particularly limited herein.

Referring to fig. 1 and 10, in some embodiments, the cross-sectional shape of the boss 122 is the same as the cross-sectional shape of the inclined hole 211, and the maximum cross-sectional size of the boss 122 is the same as the cross-sectional size of the inclined hole 211.

It can be understood that, by such an arrangement, the density of the positions where the inclined holes 211 need to be processed in the compressor partition plate 200 is reasonably increased, so that the inclined holes 211 are not easily broken when the inclined holes 211 are processed.

It should be noted that the cross-sectional shape of the boss 122 may be different from the cross-sectional shape of the inclined hole 211, as long as the formed compressor partition plate 200 is not easy to break the inclined hole 211 when the inclined hole 211 is processed by the third protrusion 210.

It should be noted that the size of the maximum cross section of the boss 122 may not be equal to the size of the cross section of the inclined hole 211, and is not described herein again.

Referring to fig. 2, 3 and 4, in some embodiments, the cross-sectional shape of the boss 122 is elliptical.

It is understood that the inclined hole 211 is a generally circular hole, and the cross section of the inclined hole 211 is an ellipse, so the cross section of the boss 122 is set to be an ellipse to better meet the requirement of machining the inclined hole.

It should be noted that the cross-sectional shape of the boss 122 may also be other shapes, such as a circle, and will not be described herein.

Note that the boss 122 has a trapezoidal vertical cross-sectional shape.

This is provided to accommodate the press molding process, and allows the boss 122 to withstand a higher pressure during the process.

It should be noted that, according to practical situations, the vertical cross-sectional shape of the boss 122 may also be set to be rectangular, square, etc., and is not limited in particular here.

It can be understood that, when processing the inclined hole 211, one side of the cutter can be processed and completed first, and the other side is still in the processing, the cutter shake phenomenon of the cutter can be more obvious this moment, the inclined hole 211 is broken up more likely, and after the fourth protrusion 1221 is provided, the position of the processing inclined hole 211 of the formed compressor partition plate 200 can form a recess with different depths, and this recess can make the cutter go out of the cutter simultaneously when processing the inclined hole 211, thereby reducing the occurrence of the broken situation of the inclined hole 211.

It can be understood that, since the inclined hole 211 is to be machined, the fourth protrusion 1221 needs to be obliquely arranged to accommodate the machining of the subsequent inclined hole 211.

Referring to fig. 5, 6, 10 and 11, in some embodiments, the angle between the angled hole 211 and the upper end face of the compressor diaphragm 200 is a first angle, and the angle between the outer sidewall and the end face of the boss 122 is a second angle, which is the same as the first angle.

It can be understood that the angle between the outer sidewall of the fourth protrusion 1221 and the end surface of the boss 122 is determined according to the angle between the inclined hole 211 and the upper end surface of the compressor partition 200, which is required to be processed by a user, so as to meet the requirement of the customer.
