The main body 1 has an air passage extending in the Z direction, and the air passage is connected to an air source, and air such as air can be ejected to the mold through the air passage. The main body 1 is provided with a first switch 2 for controlling the on-off of the air passage.

The first connector 3 is connected to the main body 1 and includes an X channel 31 extending in the X direction, a Y channel 32 extending in the Y direction, and a Z channel 33 extending in the Z direction. The solvent bottle 5 is fixed on the main body 1, and the bottle mouth 51 of the solvent bottle 5 is connected with the first connecting piece 3. The Y channel 32 is used for communicating the X channel 31 with an air channel on the main body 1, the Z channel 33 is used for communicating a bottle mouth 51 of the solvent bottle 5 with the X channel 31, and the first connecting piece 3 is further provided with a second switch 4 for controlling the opening and closing of the Z channel 33.

Specifically, one end of the X channel 31 extends through the first connecting member 3, and the other end does not extend through the first connecting member 3, that is, the first connecting member 3 has an outlet of the X channel 31, and the other end of the X channel 31 is located inside the first connecting member 3. The Y passage 32 and the Z passage 33 do not intersect with each other, in other words, the communication between the Y passage 32 and the X passage 31 and the communication between the Z passage 33 and the X passage 31 are offset. Preferably, the communication between the Y channel 32 and the X channel 31 is closer to the outlet of the X channel 31 than the communication between the Z channel 33 and the X channel 31. By adopting the scheme, gas can be sprayed out through the gas channel, the Y channel 32 and the X channel 31 in sequence, a solvent (including but not limited to a cleaning agent and a release agent) in the solvent bottle 5 is sprayed out through the bottle opening 51, the Z channel 33 and the X channel 31 in sequence, the gas channel is controlled to be switched on and off by the first switch 2, and the Z channel 33 is controlled to be switched on and off by the second switch 4, so that the gas spraying and the solvent spraying are not influenced mutually, namely, the MIM mold cleaning device can spray gas and solvent independently and spray solvent simultaneously, and people can select different spraying modes according to needs.

Wherein, the shaft sleeve 21 is fixedly arranged in the second section 112 of the air passage; the first piston 222 includes a first rod 221 disposed in the shaft housing 21, a first piston 222 connected to the first rod 221, and a second rod 223 connected to an end of the first piston 222 opposite to the first rod 221. One end (called a sleeve end 211 for short) of the sleeve 21 facing the first piston 222 is used to abut against the first piston 222 to limit the first piston 222, and the outer diameter of the sleeve end 211 is smaller than the inner diameter of the second section 112 of the gas passage, so that when the first piston 222 is pushed to the side of the first section 111 departing from the third section 113, gas can sequentially pass through the first section 111 of the gas passage and the outer edge of the sleeve end 211 to enter the third section 113 of the gas passage. The first elastic element 23 is disposed in the second section 112 of the air passage and abuts against an end of the second rod 223 of the first piston 222, which end faces away from the first piston 222. Preferably, the second rod 223 has a first inner cavity towards one end of the first elastic member 23, and the first elastic member 23 (preferably a spring) is disposed in the first inner cavity in a penetrating manner at an end abutting against the second rod 223, so that a space required for the first elastic member 23 to be disposed can be saved, and further, the size of the second connecting member 11 in the X direction can be saved, thereby facilitating the light weight of the whole device.

Specifically, for convenience of installation, the opposite wall surfaces of the movable plate 432 and the base 431 may be respectively provided with a groove for accommodating the second elastic member 42, and then the base 431 is provided with a bolt 433 for limiting the movable plate 432, so that the second elastic member 42 can be prevented from being separated from the two grooves when the movable plate 432 has an excessively large amount of movement.

The second switch 4 may also be provided with a second handle 44, and the second handle 44 is connected to the movable plate 432, so as to facilitate the operation of the person. In particular, when it is necessary to press the first switch 2 and the second switch 4 at the same time, the convenience of the operation by the first handle 25 and the second handle 44 is particularly significant.

With continued reference to fig. 7 and 8, second piston 411 may also be provided with a second passageway 4111 for communicating between port 51 of solvent bottle 5 and X-passageway 31. Specifically, the end of the second piston 411 facing the mouth 51 of the solvent bottle 5 may be provided with a second inner cavity, the second inner cavity moves relative to the mouth 51 of the solvent bottle 5, the inner diameter of the second inner cavity is substantially equal to the outer diameter of the mouth 51, the second passage 4111 is substantially in an inverted L shape, and the second passage penetrates through the second inner cavity to communicate the mouth 51 with the X passage 31, so that the sprayed solvent can be gathered and guided, and the solvent is prevented from accumulating in the Z passage 33, which affects the spraying efficiency of the solvent on the one hand and causes solvent waste on the other hand. Naturally, in order to avoid the solvent from flowing out, the second piston 411 is also provided with a sealing ring 24, and the connection point of the solvent bottle 5 and the first connecting piece 3 can be correspondingly provided with the sealing ring 24.
