Description

Technical Field

[0001] This utility model relates to the field of mold compound processing technology, specifically to a white mold compound processing device. Background Technology

[0002] Mold sealant is a material used in mold making and casting processes. Its main purpose is to create a seal between two molds to prevent molten metal from flowing out, while also helping to reduce friction and improve the mold's release performance. Mold sealant is generally composed of high-temperature wear-resistant materials, lubricants, and fillers, and possesses excellent high-temperature resistance and corrosion resistance.

[0003] The existing white molding compound production process requires mixing the raw materials first using a mixing device. After mixing, due to the different particle sizes of the various raw materials, some of which are relatively large, the mixed molding compound raw materials need to be ground to make the compound finer, improving its performance and appearance. However, in the production of white molding compound, grinding is usually done after mixing. This process takes time for both mixing and grinding. In addition, the mixing mechanism of the mixing tank is fixed and is prone to insufficient mixing during use. In this case, the molding compound needs to be mixed a second time, which inevitably increases the production time of white molding compound and reduces its production efficiency. Therefore, it has certain shortcomings.

[0004] In conclusion, it is necessary to invent a white molding compound processing device. Utility Model Content

The heating coil 130 can be a resistance wire heating tube, which can heat the raw materials during the stirring process to ensure the normal processing of white molding compound. Simply power it on during use. The mixer 100 has an internal mixing component for mixing the white molding compound material. The mixing component includes a mixing shaft 120, the top of which is rotatably connected to the top of the inner wall of the mixer 100 via a bearing seat. A mixing motor 110 is installed on the top of the outer wall of the mixer 100 to drive the mixing shaft 120 to rotate in both directions. An upper mixing blade 121 for mixing the white molding compound material is fixed to the outer side of the mixing shaft 120. The end of the upper mixing blade 121 away from the mixing shaft 120 is fixed with a mixing... The inner wall of the mixer 100 is scraped by a scraper. A stirring motor 110, when energized, drives the stirring shaft 120 to rotate, allowing the upper stirring blade 121 to mix the raw materials. The scraper, made of rubber, prevents the molding compound from adhering to the inner wall of the mixer 100. The scraper is rotatably connected to the inner wall of the mixer 100. A spiral stirring blade 122 is fixed to the outer wall of the stirring shaft 120, below the upper stirring blade 121. The spiral stirring blade 122 is positioned on the inner wall of the bottom discharge port of the mixer 100. The spiral stirring blade 122 can convey the mold compound at the bottom upward when it rotates in the opposite direction. During the feeding process, it can quickly convey the white mold compound towards the bottom outlet of the mixer 100. The inner wall of the bottom outlet of the mixer 100 needs to be fixed with a solenoid valve to control the discharge.

[0025] A grinder 200 is installed below the bottom of the outer wall of the mixer 100. The grinder 200 contains a grinding component for grinding the white molding compound material. The grinding component includes a grinding box 220. A hopper 210 is fixedly connected to the top of the outer wall of the grinding box 220. The bottom of the hopper 210 is connected to the bottom outlet of the mixer 100. The hopper 210 primarily conveys the white molding compound discharged from the mixer 100 towards the position between the grinding rollers 230. The grinding box 220 contains grinding rollers 230 for grinding the white molding compound material. Both ends of the grinding rollers 230 are connected to… The grinding rollers 230 are rotatably connected to the inner wall of the grinding box 220 via a rotating shaft. A grinding motor 232 for driving the grinding rollers 230 to rotate is fixed to the front end of the outer wall of the grinding box 220. A transmission gear set 231 is provided at the rear end of the outer wall of the grinding box 220, corresponding to the position of the grinding rollers 230. The transmission gear set 231 is fixed to the rotating shaft connected to the rear end of the grinding rollers 230, and adjacent transmission gear sets 231 mesh with each other. When the grinding motor 232 is energized, it can drive the connected grinding rollers 230 to rotate. When one grinding roller 230 rotates, the transmission gear set 231... The meshing allows another grinding roller 230 to rotate simultaneously, thereby grinding the falling white molding compound. Multiple sets of grinding rollers 230 can be set as needed, with gradually decreasing spacing between them to ensure thorough grinding of the white molding compound. Discharge augers 300 are fixedly installed through both sides of the inner wall of the grinder 200. The bottom discharge end of the grinding box 220 is connected to the feeding port at the center of the top of the inner wall of the discharge auger 300. The discharge auger 300 is mainly used to transport unmixed white molding compound back to the mixer 100 for further mixing as needed. Alternatively, the mixed white molding compound can be discharged. The inner walls of the discharge auger 300 are rotatably connected to the spiral conveyor blades 310 for conveying materials. The outer wall of the discharge auger 300 is fixed with a drive motor 320 for driving the spiral conveyor blades 310 to rotate in both directions. The bottom of the inner wall of the discharge auger 300 and both sides of the grinder 200 are provided with discharge ports.

[0026] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. After completion, the raw materials for preparing white molding compound are added to the stirrer 100 through the feeding pipe 141 via the material lifting equipment (existing technology, not shown in the figure). Then, the personnel can control the heating coil 130 to be powered on to heat the inside of the stirrer 100 through the controller. Then, the stirring motor 110 is powered on to drive the stirring shaft 120, the upper stirring blade 121 and the spiral stirring blade 122 to rotate, thereby mixing and stirring the added white molding compound raw materials, so that they are fully mixed and prepared into white molding compound.

[0027] After mixing for a period of time, in order to reduce the occurrence of dead zones at the bottom and to make the white molding compound finer, the controller can open the solenoid valve at the discharge port of the mixer 100, allowing the white molding compound in the mixer 100 to fall into the collecting hopper 210 through the discharge port. The collecting hopper 210 collects the white molding compound and conveys it to the grinding roller 230. At the same time, the operator can turn on the power to start the grinding motor 232 to drive the grinding roller 230 to rotate. The rotating grinding roller 230 grinds the falling white molding compound, and the ground white molding compound falls into the... If the white molding compound is not fully mixed within the discharge auger 300, the drive motor 320 will drive the spiral conveyor blade 310 to rotate in the reverse direction, causing the white molding compound to fall into the return auger 400 through the discharge port on the right. The return auger 400 will then transport it back to the mixer 100 through the return pipe 140 for further mixing. If the white molding compound is fully mixed, the drive motor 320 will drive the spiral conveyor blade 310 to rotate in the forward direction, allowing the white molding compound to be discharged into the collection container through the discharge port on the left for storage, thus enabling the next step of production.
