Description

Technical Field

[0001] The utility model relates to the technical field of mold polishing, in particular to a mold capable of automatically polishing a mold cavity. Background Art

[0002] Powder compacting, also known as powder die pressing, is a widely used forming method in powder metallurgy production, second only to sintering in importance. Die pressing involves loading metal powder or a powder mixture into a female die, applying pressure to the powder through a die punch, and releasing the pressure to release the compact from the die, completing the forming process. The process includes powder loading, compacting, demolding, and resetting. Die-formed parts typically adopt simple, symmetrical shapes, avoiding components with varying cross-sections, such as narrow grooves, to facilitate molding and compaction. Existing molds capable of automatically polishing the die cavity typically utilize a separate scraper blade. This scraper blade typically requires pre-cutting before use. Furthermore, the scraper blade remains in use and cannot be adjusted based on usage. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a mold that can automatically polish the mold cavity to solve the technical problem that the scraper generally needs to be cut in advance and can only be used after cutting is completed. At the same time, when in use, the scraper always remains in use and cannot be adjusted according to the usage situation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold that can automatically polish a mold cavity, comprising an outer mold, the interior of the outer mold is slidably connected to a pressure column mechanism, the pressure column mechanism comprises a base, a first mounting block is provided on the top of the base, a second mounting block is provided on the top of the first mounting block, a first airbag is sleeved on one side of the bottom of the second mounting block, a first silicone layer is fixedly connected to the outside of the first airbag, and a polishing sheet layer is fixedly connected to the outside of the first silicone layer.

[0005] By adopting the above technical solution, the pressure column mechanism is slidably connected inside the outer mold, so that the pressure column mechanism can move inside the mold, thereby driving the polishing layer to polish the inner wall of the outer mold, realizing automated polishing and improving polishing efficiency.

[0006] Furthermore, a second airbag is sleeved on one side of the bottom of the first mounting block, and a second silicone layer is fixedly connected to the outer side of the second airbag.

[0015] By adopting the above technical solution, one end of the first through hole is connected to the position of the first airbag, so that the external inflation device can inflate the first airbag through the first air tube and the first through hole. When the first airbag is inflated, it can squeeze the first silicone layer, and then press the polishing sheet layer to the inner wall of the outer mold, so as to achieve full contact between the polishing sheet layer and the inner wall of the outer mold, thereby improving the polishing effect and quality, and making the polishing operation more uniform and delicate.

[0016] Furthermore, one end of the second through hole is connected to the location of the second airbag, and the second airbag is connected to the external inflation device through the second air tube.

[0017] By adopting the above technical solution, one end of the second through hole is connected to the location of the second airbag, so that the external inflation device can inflate the interior of the second airbag through the second air tube and the second through hole.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Example 1:

[0038] A mold that can automatically polish the mold cavity, such as Figures 1-4 As shown, it includes an outer mold 1, and the inner part of the outer mold 1 is slidably connected to a pressure column mechanism 2, and the pressure column mechanism 2 includes a base 201, a first mounting block 202 is provided on the top of the base 201, a second mounting block 203 is provided on the top of the first mounting block 202, and a first air bag 204 is sleeved on one side of the bottom of the second mounting block 203, and a first silicone layer 205 is fixedly connected to the outer side of the first air bag 204, and a polishing sheet layer 206 is fixedly connected to the outer side of the first silicone layer 205. By arranging the first air bag 204 between the first mounting block 202 and the second mounting block 203, and fixing the first silicone layer 205 and the polishing sheet layer 206 in sequence on the outer side of the first air bag 204, during the polishing process, the first air bag 204 can be inflated to expand and squeeze the first silicone layer 205, and then the polishing sheet layer 206 can be pressed against the inner wall of the outer mold 1, so that the polishing sheet layer 206 is fully abutted against the inner wall of the outer mold 1, thereby improving the polishing effect and quality.

[0039] See Figure 3 A second airbag 207 is sleeved on one side of the bottom of the first mounting block 202, and a second silicone layer 208 is fixedly connected to the outer side of the second airbag 207. When the maintenance function is needed, the second airbag 207 can be inflated to expand and squeeze the second silicone layer 208. Since the second silicone layer 208 has good elasticity and adaptability, it can fit tightly on the inner wall of the outer mold 1. It can cooperate with the cleaning liquid introduced from the outside to clean and maintain the inner wall of the outer mold 1 through the second silicone layer 208, thereby effectively extending the service life of the mold and ensuring the stability of the polishing effect.

[0040] See Figure 3 A cleaning cloth layer 209 is fixedly connected to the outside of the second silicone layer 208. The cleaning cloth layer 209 is made of polyester fiber. The cleaning cloth layer 209 enhances the maintenance function of the mold. When the second airbag 207 is inflated and squeezes the second silicone layer 208, the cleaning cloth layer 209 will also fit tightly against the inner wall of the outer mold 1. In conjunction with the cleaning liquid introduced from the outside, the cleaning cloth layer 209 can perform more detailed and in-depth cleaning of the inner wall of the outer mold 1, removing hard-to-reach stains and residues, thereby further improving the cleaning effect and maintenance quality of the mold.

[0041] See Figure 4A liquid inlet channel 210 is provided inside the base 201. There are multiple liquid inlet channels 210, and the multiple liquid inlet channels 210 are evenly arranged at equal distances. The setting of multiple liquid inlet channels 210 also enhances the cleaning efficiency of the mold. During the cleaning process, the cleaning liquid can be introduced into the interior of the mold through the multiple liquid inlet channels 210 at the same time, which speeds up the flow of the cleaning liquid and enables stains and residues to be cleaned faster.

[0042] See Figure 1 and Figure 2 A first through hole 211, a second through hole 212 and a bolt through hole 213 are respectively provided between the liquid inlet channel 210. The setting of the first through hole 211 and the second through hole 212 also provides more functional expansion space for the mold. The air pipe can be installed through the first through hole 211 and the second through hole 212 to achieve automation and intelligence, while the bolt through hole 213 facilitates the installation and disassembly of the mold, making the maintenance and replacement of the mold more convenient.

[0043] See Figure 3 One end of the first through hole 211 is connected to the location of the first airbag 204. The first airbag 204 is connected to the external inflation device through the first air tube 216. The inflation of the first airbag 204 is controlled by the external inflation device, and the polishing pressure can also be adjusted. According to different polishing requirements, the inflation pressure can be adjusted to achieve the best polishing effect.

[0044] See Figure 3 One end of the second through hole 212 is connected to the location of the second airbag 207. The second airbag 207 is connected to the external inflation device through the second air pipe 217. The inflation of the second airbag 207 is controlled by the external inflation device, and the cleaning pressure can also be adjusted. According to different cleaning requirements, the inflation pressure can be adjusted to achieve the best cleaning effect.

[0045] See Figure 1 and Figure 2 The pressing column mechanism 2 is provided with two groups, and the internal sliding connection of the pressing column mechanism 2 is provided with the molding column 3, so that the molding column 3 can cooperate with the outer mold 1 to form a mold cavity, thereby completing the molding operation of workpieces with different shapes.

[0046] The implementation principle of the utility model is as follows: first, when in use, the outer mold 1, the two pressure column mechanisms 2 and the mold column 3 cooperate to form a pressure mechanism, so that a compression molding can be formed;

[0047] When it is necessary to scrape the interior, the external inflation mechanism inflates the first airbag 204 through the first air tube 216, causing the first airbag 204 to expand outward. The expanded first airbag 204 squeezes the first silicone layer 205, so that the first silicone layer 205 can press the polishing sheet layer 206 into the interior of the outer mold 1, so that the polishing sheet layer 206 is fully abutted against the inner wall of the outer mold 1, so that during the movement of the two pressure column mechanisms 2, the polishing sheet layer 206 can be driven to polish the inner wall of the outer mold 1;

[0048] When the cleaning cloth layer 209 is needed to perform maintenance on the interior, the external cleaning liquid is introduced into the interior of the outer mold 1 from the liquid inlet channel 210, and the second air pipe 217 inflates the interior of the second airbag 207, causing the second airbag 207 to expand outward. The expanded second airbag 207 squeezes the second silicone layer 208, so that the second silicone layer 208 can press the cleaning cloth layer 209 into the interior of the outer mold 1, thereby achieving full contact between the cleaning cloth layer 209 and the inner wall of the outer mold 1, so that during the movement of the two pressure column mechanisms 2, the cleaning cloth layer 209 can be driven to perform maintenance on the inner wall of the outer mold 1.

[0049] Example 2:

[0050] See Figure 4 One end of the bolt through hole 213 is opened to the bottom position of the second mounting block 203, and a threaded hole 214 is opened at the bottom of the second mounting block 203. The bolt connection method also allows the mold to maintain the tightness and stability of the connection part even when it is subjected to greater polishing or cleaning pressure during long-term use, avoiding the problem of mold damage or poor polishing and cleaning effects caused by loose connection.

[0051] See Figure 4 The base 201 is fixedly connected to the first mounting block 202 and the second mounting block 203 through bolts 215 and threaded holes 214. The connection method of bolts 215 and threaded holes 214 also facilitates the disassembly and maintenance of the mold. When the mold needs to be cleaned, maintained or parts need to be replaced, the base 201 or other parts can be easily disassembled by loosening the bolts 215 without using complicated tools or equipment.

[0052] The implementation principle of the present invention is as follows: first, during installation, the first installation block 202 and the second installation block 203 can be tightened by means of the bolts 215 to achieve overall rapid installation.

[0053] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0054] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
