Fig. 2 is structural schematic diagram when the application forging ejects forge piece after the completion.

Label is in figure:Upper mold 1, lower die 2, lower die face 21, lower mode cavity 22, angled slide block 23, air bag chamber 24, air bag 241, Inflator 242, gear 243, down-pressed pole 244, gas bar 245, groove body 25, limiting device 26.

Specific implementation mode

The invention will be further described in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.

As shown in Figure 1, a kind of forging mold, including upper mold 1 and lower die 2, upper mold 1 are connect with hold-down devices, hold-down devices Driving upper mold is moved up perpendicular, and specific hold-down devices can be cylinder or oil cylinder, and the lower die 2 includes lower die face 21 under The lower mode cavity 22 that die face 21 surrounds, the upper mold 1 include upper mold 1 face opposite with lower die 2, and by the upper of 1 face of upper mold besieged city Die cavity, when being forged, upper mold 1 pushes, and when upper mold 1 and the closure of lower die 2, upper cavity and lower mode cavity 22 surround mold Chamber is to be forged.

As depicted in figs. 1 and 2,22 bottom of the lower mode cavity is provided with groove body 25, and engaging in the groove body 25 has angled slide block 23, The angled slide block 23 is matched with the groove body 25, when angled slide block 23 is properly latched in groove body 25, the upper end of angled slide block 23 Face and the bottom surface of lower mode cavity 22 maintain an equal level, and hollow air bag chamber 24 is provided in the mold, and groove body 25 connects with air bag chamber 24 Logical, 25 bottom of groove body is provided with limiting device 26, and limiting device 26 is used to that angled slide block 23 to be avoided to fall in air bag chamber 24, Specifically, the limiting device 26 is one week convex edge for being fixedly installed in 25 bottom end of groove body, gas is provided in the air bag chamber 24 Capsule 241, inflator 242, gear 243 and down-pressed pole 244, the air bag 241 are contacted with the bottom surface of angled slide block 23, and air bag 241 is used for The angled slide block 23, the air bag 241 is supported to be connect with inflator 242, air bag 241 and the junction of inflator 242 are provided with unidirectionally Valve, the check valve are only capable of that gas is made to enter in air bag 241, and wherein gas bottom end is also equipped with breather check valve, the air inlet Check valve is only capable of that gas is made to enter in inflator 242, the interior gas bar 245 for being useful for inflating that is slidably matched on the inflator 242, Specific gas bar 245 includes the piston part of bar portion and connection and bar portion bottom end, the diameter of the piston part and the internal diameter one of inflator 242 It causes, survey edge and the gas interior palette of piston part, the first vertical rack is fixedly installed in the bar portion of the gas bar 245, First rack and pinion 243 engages, and 243 other side of the gear is engaged with the second rack, and second rack is fixed Be installed on the down-pressed pole 244, sliding rail be installed on the madial wall of the air bag chamber 24, the down-pressed pole 244 with it is described Sliding rail is slidably matched, and the down-pressed pole 244 can be vertically movable along the sliding rail, so that the down-pressed pole 244 can be in airbag chamber The inside and outside sliding in room 24, the down-pressed pole 244 partially pass through the lower die face, and the piston part of cylinder also is located at inflator 242 most at this time Low side, when the upper mold 1 and the closure of lower die 2, the down-pressed pole 244 is pressed into the air bag chamber 24 by the upper mold 1 works as In, wherein the weight of cylinder is more than the weight of the down-pressed pole 244.

The workflow of the application is:When starting forging, as shown in Figure 1, upper mold 1 pushes, depressed under 1 face of upper mold at this time Compression bar 244 drives the second rack on down-pressed pole 244 downward, and the second rack drives gear 243 rotation, gear 243 drives first Rack is upward, and upwards, inflator 242 is evacuated the first rack drives gas bar 245 from the external world at this time, and air bag 241 is in unaerated at this time State, angled slide block 23 is located in groove body 25, is forged when upper cavity is closed with lower mode cavity 22, after the completion of forging, As shown in Fig. 2, upper mold 1 moves up, not compression bar 244 under extrusion of upper mold 1 at this time, at this point, inflator 242 declines under the effect of gravity, Gas gas 242 in inflator 242 is entered by check valve in air bag 241, to be inflated to air bag 241, air bag 241 Angled slide block 23 is ejected into groove body 25 after inflation, to make angled slide block 23 eject forge piece.

As depicted in figs. 1 and 2, further, in order to deflate to air bag 241 after taking out forging soon, the air bag 241 and Manual air-release valves, the Manual air-release valves be set on the lateral wall of lower die 2.Specifically the Manual air-release valves can be Ball valve moved twisting Manual air-release valves, and air bag 241 is made to be in communication with the outside, at this time 23 times pressuring gasbags of angled slide block 241, thus by gas Air discharge band in capsule 241 is extraneous, and angled slide block 23 is fallen after rise again to groove body 25.

The application is by being arranged air bag 241 and inflator 242, so as to be carried out automatically to air bag 241 after the completion of forging Inflation, so as to realize the function of automatic ejection forge piece in the case where external power supply is not separately provided.

Embodiment described above is only to absolutely prove the preferred embodiment invented and lifted, and the protection domain of invention is not It is limited to this.Those skilled in the art on the basis of invention made by equivalent substitute or transformation, in the protection model of invention Within enclosing.The protection domain of invention is subject to claims.
