Description

Technical Field

[0001] The present invention relates to the field of mold cleaning, and particularly to a fully automatic powder mold cleaning system. Background Art

[0002] The applicant has developed a powder mold to be cleaned, which includes: an outer ring body and an inner core. An inner core that can be lifted is installed inside the outer ring body. A powder cavity is formed between the upper surface of the inner core and the inner wall of the outer ring body. A bottom plate is provided at the bottom of the inner core, and the outer diameter of the bottom plate is smaller than the diameter of the bottom of the inner hole of the outer ring body, so that there is a gap between the inner core and the inner wall of the inner hole of the outer ring body, and at the same time, the inner core can be prevented from detaching from the outer ring body. The powder cavity is used for loading powder. Since high-precision products are made from powder, there should be no powder residue in the powder mold to be cleaned. Then, how to clean the powder mold to be cleaned is the topic discussed in this application.

The fully automatic mold cleaning machine includes: a mold cleaning mechanism, which includes two symmetrically arranged guide rails. Transmission components are respectively arranged on the two guide rails, and a cleaning component is arranged between the two guide rails. The transmission component drives the cleaning component to move linearly along the guide rail. The cleaning component includes a brush and a plurality of air blowing valves. The plurality of air blowing valves are equidistantly arranged along the length direction of the brush. One end of the plurality of air blowing valves extends into the brush.

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention clearer and easier to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners:

[0025] As Figures 1 to 3 shown, the present invention discloses a fully automatic powder mold cleaning system, including: a conveying device 4, a workbench, a cleaning device and a lifting device 2. The conveying device 4 is used to convey the powder mold 3 to be cleaned, and the middle of the conveying device 4 is a cleaning position;

[0026] The conveying device 4 is installed on the workbench. The cleaning execution end of the cleaning device is located above the cleaning position of the conveying device 4. The lifting device 2 is installed at the cleaning position of the conveying device 4. The output end of the lifting device 2 is used to pass through the conveying device 4 and then lift the powder mold 3 to be cleaned to the cleaning execution end of the cleaning device;

[0027] The lifting device 2 includes: a first lifting mechanism 21 and a second lifting mechanism 22. The output end of the first lifting mechanism 21 is installed with the second lifting mechanism 22, and the powder mold 3 to be cleaned is placed on the output end of the first lifting mechanism 21. The first lifting mechanism 21 is used to lift the powder mold 3 to be cleaned to the output end of the cleaning device. The output end of the second lifting mechanism 22 is located below the inner core 32 in the powder mold 3 to be cleaned. The second lifting mechanism 22 is used to lift the liftable inner core 32 in the powder mold 3 to be cleaned during cleaning.

[0028] The cleaning device includes a cleaning cover 11 and a cleaning mechanism. An upper cleaning chamber is provided inside the cleaning cover 11. The upper cleaning chamber is for the to-be-cleaned powder mold 3 lifted by the lifting device 2 to extend into for cleaning. The top of the cleaning cover 11 is connected to the cleaning mechanism. When cleaning, the cleaning cover 11 is buckled above the cleaning powder mold to form the upper cleaning chamber, avoiding powder leakage during the cleaning of the upper cleaning chamber. The cleaning cover 11 is fixed above the lifting device 2 through the first mounting frame, and the lifting device 2 is mounted below the cleaning cover 11 through the second mounting frame.

[0029] The cleaning mechanism includes a jetting mechanism 121 and a suction mechanism 122. The output end of the jetting mechanism 121 passes through the top of the cleaning cover 11 and communicates with the upper cleaning chamber. The input end of the suction mechanism 122 passes through the cleaning cover 11 and communicates with the upper cleaning chamber. The cleaning mechanism composed of the jetting mechanism 121 and the suction mechanism 122 can blow and suck the upper cleaning chamber, thereby achieving the cleaning function.

[0030] The jetting mechanism 121 includes a first jet pipe 1211 and a jet pump. One end of the first jet pipe 1211 is communicated with the output end of the jet pump, and the other end of the first jet pipe 1211 is communicated to the cleaning cover 11. The suction mechanism 122 includes a first suction pipe 1221 and a suction pump. One end of the first suction pipe 1221 is communicated with the input end of the suction pump, and the other end of the first suction pipe 1221 is communicated to the cleaning cover 11. The jet pump uses the first jet pipe 1211 to blow air into the upper cleaning chamber.

[0031] On the outer wall of the bottom of the cleaning cover 11, a protruding ring cover 110 protrudes. A bottom spray chamber 111 is formed between the inner wall of the protruding ring cover and the outer wall of the bottom of the cleaning cover 11. An air blowing hole 112 is opened on the bottom of the cleaning cover 11, and the air blowing hole 112 communicates the upper cleaning chamber with the bottom spray chamber 111; A second air spray pipe 1213 passes through the protruding ring cover 110. One end of the second air spray pipe 1213 is communicated with the bottom spray chamber 111, and the other end of the second air spray pipe 1213 is communicated with the output end of the air jet pump. Since the first air suction pipe 1221 blows air vertically downward, the inner wall of the powder mold 3 to be cleaned has an adhesion effect on the powder. After the first air suction pipe 1221 blows air, it is very difficult to make the powder fully separate from the inner wall of the powder mold 3 to be cleaned. For the above reasons, a protruding ring cover 110 is designed at the bottom of the cleaning cover 11 to form a bottom spray chamber 111, and then an air blowing hole 112 is opened. The air blowing hole 112 is communicated with the bottom spray chamber 111, so as to realize blowing air from the bottom of the cleaning cover 11, achieving the effect of raising dust in the upper cleaning chamber, reducing the probability of dust adhering to the powder mold 3 to be cleaned. With the cooperation of the subsequent third air spray pipe 1214, the powder hardly adheres to the inner wall of the powder mold 3 to be cleaned. Without using a brush and a driving mechanism for driving the brush externally, the dust raising effect is improved, the wear of the powder mold 3 to be cleaned caused by using a brush is avoided, the waste of materials and resources caused by using a brush is also avoided, the production cost is reduced, and the cleaning effect is improved.

[0032] The output end of the second lifting mechanism 22 is communicated with the inner cavity at the bottom of the powder mold 3 to be cleaned to form a lower cleaning chamber; The output end of the air jet pump is also communicated with one end of a third air spray pipe 1214, and the other end of the third air spray pipe 1214 is communicated with the lower cleaning chamber; The input end of the air suction pump is also communicated with one end of a second air suction pipe 1223, and the other end of the second air suction pipe 1223 is communicated with the lower cleaning chamber. After the third air spray pipe 1214 and the second air suction pipe 1223 cooperate, the lower cleaning chamber is cleaned, avoiding the powder falling into the lower cleaning chamber due to the lifting of the inner core 32. The upper cleaning chamber is above the inner core 32, and the lower cleaning chamber is below the inner core 32, so as to realize the all-round cleaning of the mold to be cleaned and improve the cleaning effect of the mold to be cleaned.

[0033] The output end of the second lifting mechanism 22 includes: a base 221 and a spray head 222. The spray head 222 is installed on the base 221. The spray head 222 is provided with an air outlet cavity and an air suction cavity. The air outlet cavity is communicated with the third spray pipe 1214, and the air suction cavity is communicated with the second suction pipe 1223. Since the output end of the second lifting mechanism 22 supports the inner core 32 in the powder mold 3 to be cleaned, the output end of the second lifting mechanism 22 needs to be lifted and lowered. Therefore, the third spray pipe 1214 and the second suction pipe 1223 are installed at the spray head 222 and the base 221 at the output end of the second lifting mechanism 22. The output end of the third spray pipe 1214 and the input end of the second suction pipe 1223 can be lifted and lowered together and extend into the outer ring body 31 of the powder mold 3 to be cleaned, so as to fully clean the powder at the bottom inside the outer ring body 31 of the powder mold 3 to be cleaned.

[0034] The spray head 222 includes: a bottom ring 2221, a head body 2222, an upper top plate 2223 and a connecting core 2224; the bottom ring 2221 is detachably connected to the base 221. The third spray pipe 1214 and the second suction pipe 1223 are installed on the base 221. The bottom ring 2221 is provided with a first spray cavity and a first suction cavity. The first spray cavity is communicated with the third spray pipe 1214, and the first suction cavity is communicated with the second suction pipe 1223; the head body 2222 is buckled on the bottom ring 2221. The head body 2222 is provided with a second spray cavity and a second suction cavity. The second spray cavity is communicated with the first spray cavity, and the second suction cavity is communicated with the first suction cavity; an upper top plate 2223 is arranged above the head body 2222. The upper top plate 2223 is fixed to the top end of the connecting core 2224. The middle part of the connecting core 2224 passes through the head body 2222, and the head plate body is detachably connected to the bottom ring 2221. The connecting core 2224 connects the upper top plate 2223 to the bottom ring 2221, and at the same time, the head body 2222 located in the middle is pressed tightly on the bottom ring 2221, so as to facilitate the opening of the irregular second spray cavity and second suction cavity on the head body 2222.

[0035] An elastic buffer mechanism 5 is arranged at the top of the cleaning cover 11.

[0036] The elastic buffer mechanism 5 includes: a guide tube 51, a buffer column 52 and a spring 53. The guide tube 51 is located at the center of the top of the cleaning cover 11. The lower end of the guide tube 51 extends into the upper cleaning cavity. A buffer column 52 is installed in the guide tube 51. The buffer column 52 can move up and down relatively in the guide tube 51. The top of the buffer column 52 is connected to the inner top of the guide tube 51 through a spring 53. The buffer column 52 is used to press against the inner core 32 of the powder mold 3 to be cleaned when the cleaning cover 11 is buckled on the powder mold 3 to be cleaned. In the elastic buffer mechanism 5, the buffer column 52 presses against the inner core 32. When the second lifting mechanism 22 drives the inner core 32 to move up and down, the inner core 32 is clamped, preventing the inner core 32 from protruding too much from the outer ring body 31 and offsetting, resulting in the inner core 32 being unable to return to the outer ring body 31, ensuring the stability of the relative position of the inner core 32 and the outer ring body 31 during the cleaning process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
