Abstract
Description
Technical Field
[0001] This utility model relates to a cleaning device, specifically a powder mold cleaning device. Background Technology
[0002] The applicant has developed a powder mold for cleaning, comprising an outer ring and an inner core. The inner core, which can be raised and lowered, is installed within the outer ring. The upper surface of the inner core and the inner wall of the outer ring form a powder cavity. A base plate is provided at the bottom of the inner core, the outer diameter of which is smaller than the bottom diameter of the inner hole of the outer ring. This creates a gap between the inner core and the inner wall of the inner hole of the outer ring, while also preventing the inner core from detaching from the outer ring. The powder cavity is used to hold powder. Since powder is used to manufacture high-precision products, there must be no powder residue in the powder mold for cleaning. Therefore, how to clean the powder mold is the topic discussed in this application.
[0003] Chinese patent discloses a fully automatic mold cleaning machine with application number CN201922442029.6. This fully automatic mold cleaning machine includes: a mold cleaning mechanism comprising two symmetrically arranged guide rails, each with a transmission component, and a cleaning component positioned between the two guide rails. The transmission components drive the cleaning component to move linearly along the guide rails. The cleaning component includes a brush and multiple air valves, which are equidistantly arranged along the length of the brush. One end of each air valve extends into the brush. A front baffle and a rear baffle are respectively located at opposite ends of the brush. The air valves are positioned between the front baffle and the brush. Multiple upper and lower suction pipes are connected to the front baffle. A dust collection mechanism is used to collect dust sucked out by the upper and lower suction pipes. The dust collection mechanism includes a dust collection box, a fan disposed within the dust collection box, and a dust collection box filter element.
[0004] Although the fully automatic mold cleaning machine can clean the mold, it still has the following problems: In the target powder mold to be cleaned, the inner core can be raised and lowered, and there is a possibility that powder may get stuck between the outer ring and the inner core. There is also a possibility that powder may enter the bottom plate edge through the gap between the outer wall of the inner core and the inner wall of the inner hole of the outer ring. It is difficult to remove the powder between the inner wall of the outer ring and the inner core by simply blowing and sucking or by brushing. Utility Model Content

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figure 1 as well as Figure 2 As shown, this utility model discloses a powder mold cleaning device, including: a cleaning device and a lifting device 2; the cleaning execution end of the cleaning device is located above the lifting device 2; the lifting device 2 includes: a first lifting mechanism 21 and a second lifting mechanism 22, the second lifting mechanism 22 is installed on the output end of the first lifting mechanism 21, 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, and 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.
[0022] The cleaning device includes a cleaning hood 11 and a cleaning mechanism. The cleaning hood 11 has an upper cleaning chamber, into which the powder mold 3, which is lifted by the lifting device 2, is inserted for cleaning. The top of the cleaning hood 11 is connected to the cleaning mechanism. During cleaning, the cleaning hood 11 is fastened to the upper cleaning chamber above the powder mold, preventing powder leakage during cleaning. The cleaning hood 11 is fixed above the lifting device 2 by a first mounting bracket, and the lifting device 2 is mounted below the cleaning hood 11 by a second mounting bracket.
[0023] 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 hood 11 and communicates with the upper cleaning chamber, while the input end of the suction mechanism 122 passes through the cleaning hood 11 and communicates with the upper cleaning chamber. The cleaning mechanism consisting of the jetting mechanism 121 and the suction mechanism 122 can blow and suck air into the upper cleaning chamber, thereby achieving the cleaning function.
[0024] The jet mechanism 121 includes a first jet pipe 1211 and a jet pump. One end of the first jet pipe 1211 is connected to the output end of the jet pump, and the other end of the first jet pipe 1211 is connected to the cleaning hood 11. The suction mechanism 122 includes a first suction pipe 1221 and a suction pump. One end of the first suction pipe 1221 is connected to the input end of the suction pump, and the other end of the first suction pipe 1221 is connected to the cleaning hood 11. The jet pump uses the first jet pipe 1211 to blow air into the upper cleaning chamber.
[0025] A protruding ring cover 110 protrudes from the bottom outer wall of the cleaning hood 11, forming a bottom spray cavity 111 between the inner wall of the ring cover and the bottom outer wall of the cleaning hood 11. An air blowing hole 112 is provided on the bottom of the cleaning hood 11, connecting the upper cleaning cavity and the bottom spray cavity 111. A second air jet pipe 1213 passes through the protruding ring cover 110, with one end of the second air jet pipe 1213 connected to the bottom spray cavity 111 and the other end connected to the output end of the air jet pump. Because the first suction pipe 1221 blows air vertically downwards, the inner wall of the powder mold 3 to be cleaned has an adhesive effect on the powder, making it difficult for the powder to fully detach from the inner wall of the powder mold 3 after the first suction pipe 1221 blows air. Based on the above reasons, a protruding ring cover 110 is designed at the bottom of the cleaning hood 11 to form a bottom spray chamber 111. Subsequently, an air blowing hole 112 is opened, which is connected to the bottom spray chamber 111. This enables air to be blown from the bottom of the cleaning hood 11, achieving the effect of dust dispersion in the upper cleaning chamber and reducing the probability of dust adhering to the powder mold 3 to be cleaned. With the subsequent cooperation of the third air jet pipe 1214, the powder adheres almost to the inner wall of the powder mold 3 to be cleaned. The dust dispersion effect is improved without using a brush or an external drive mechanism for the brush, avoiding wear of the powder mold 3 to be cleaned caused by using a brush, and also avoiding waste of materials and resources caused by using a brush. This reduces production costs and improves the cleaning effect.
[0026] The output end of the second lifting mechanism 22 is connected to the bottom inner cavity of the powder mold 3 to be cleaned, forming a lower cleaning chamber. The output end of the jet pump is also connected to one end of the third jet pipe 1214, and the other end of the third jet pipe 1214 is connected to the lower cleaning chamber. The input end of the suction pump is also connected to one end of the second suction pipe 1223, and the other end of the second suction pipe 1223 is connected to the lower cleaning chamber. This achieves the cleaning of the lower cleaning chamber by the cooperation of the third jet pipe 1214 and the second suction pipe 1223, preventing the powder from 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, thus achieving all-round cleaning of the mold to be cleaned and improving the cleaning effect of the mold.
[0027] The output end of the second lifting mechanism 22 includes a base 221 and a nozzle 222. The nozzle 222 is mounted on the base 221. The nozzle 222 has an air outlet chamber and an air intake chamber. The air outlet chamber is connected to the third air jet pipe 1214, and the air intake chamber is connected to the second air intake pipe 1223. Since the output end of the second lifting mechanism 22 supports the inner core 32 of the powder mold 3 to be cleaned, the output end of the second lifting mechanism 22 needs to be raised and lowered. Therefore, the third air jet pipe 1214 and the second air intake pipe 1223 are installed at the nozzle 222 and the base 221 at the output end of the second lifting mechanism 22. The output end of the third air jet pipe 1214 and the input end of the second air intake pipe 1223 can be raised and lowered together and extended into the outer ring 31 of the powder mold 3 to be cleaned, so as to fully clean the powder inside the bottom of the outer ring 31 of the powder mold 3 to be cleaned.
[0028] The nozzle 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, and a third air jet pipe 1214 and a second air intake pipe 1223 are installed on the base 221. The bottom ring 2221 has a first spray chamber and a first suction chamber, the first spray chamber is connected to the third air jet pipe 1214, and the first suction chamber is connected to the second air intake pipe 1223; the head body 2222 is fastened to the bottom ring 2221, and the head body 2222 has a second spray chamber and a second suction chamber, the second spray chamber is connected to the first spray chamber, and the second suction chamber is connected to the first suction chamber; an upper top plate 2223 is provided above the head body 2222, and the upper top plate 2223 is fixed to the top of the connecting core 2224. The middle part of the connecting core 2224 passes through the head body 2222, and the head body is detachably connected to the bottom ring 2221. This allows the connecting core 2224 to connect the upper top plate 2223 to the bottom ring 2221, and also allows the head body 2222 located in the middle to be pressed tightly onto the bottom ring 2221, thereby facilitating the opening of an irregular second spray chamber and a second suction chamber on the head body 2222.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
