Description

Technical Field

[0001] The utility model relates to the technical field of hardware production, in particular to a high-efficiency molding machine for hardware production. Background Art

[0002] Most of the metal products in the manufacturing industry and the general parts and components in the general equipment manufacturing and other related products constitute the "small hardware" in the usual sense. The responsibility of "small hardware" is to provide parts and production tools to manufacturing enterprises, rather than as industry-specific equipment for final use. At present, in the hardware production and processing process, a shock-compression molding machine is needed to manufacture the casting sand mold of the hardware products. Compared with the previous manual method, the use of a shock-compression molding machine to make sand molds has improved the efficiency of hardware sand mold making to a certain extent. However, during the use of the current shock-compression molding machine, the molded template and the machine body are fixed with multiple bolts. When the template needs to be replaced when manufacturing sand molds of different products, the operation is cumbersome. In addition, after the shock-compression is completed and when the sand mold is shocked again, the sand that falls on the surface of the template needs to be cleaned manually, which is inconvenient to use. Therefore, we propose a high-efficiency molding machine for hardware production to solve the above problems. Utility Model Content

The side walls of the plate 4 are rotatably connected with a rotating shaft 5 through a bearing, one end of the rotating shaft 5 is fixed with a hollow plate 6, two cross plates 7 are fixed between the two hollow plates 6, the tops of the two hollow plates 6 are clamped with a template 8, and the insides of the hollow plates 6 are provided with a limit assembly 9 for fixing the template 8. A top plate 10 is provided above the base 1, and a second hydraulic cylinder 11 is fixed on the top of the top plate 10. The ejection end of the second hydraulic cylinder 11 slides through the top plate 10 and extends to the bottom thereof and is fixed with a pressing plate 12. The bottom of the top plate 10 is provided with an air blow The collecting component 13 and the top of the base 1 are provided with a rotating mechanism 14 for driving the top plate 10 to rotate. When the molding machine is in use, the molding frame limit can be placed on the top of the template 8. After manually pouring sand into the inside of the molding frame 8, the first hydraulic cylinder 3 is used to drive the movable plate 4 to move back and forth, so that the sand inside the molding frame can be vibrated and compacted. Then the second hydraulic cylinder 11 can be started to drive the pressing plate 12 to move down, so that the sand inside the molding frame can be compacted. The two sides of the template 8 are the matching surfaces of the product manufacturing sand mold. When the first hydraulic cylinder 3 lifts the movable plate 4 to a suitable height, the motor can be started to drive one of the rotating shafts 5 to rotate, so that the template can be turned over. After the compaction operation is completed and the molding frame is removed, the top plate 10 can be driven to rotate ninety degrees by the rotating mechanism 14. At this time, the air blowing collecting component 13 will be located above the sand mold, and then it will be moved down, so that the excess sand can be automatically blown off and collected. After the later operation limit component 9 releases the restriction on the template 8, it can be removed and replaced.

One end of the plate 8 is clamped and limited between the two limit blocks 904, and a moving rod 905 is fixed to one side wall of the tooth frame 903. One end of the moving rod 905 slides through the hollow plate 6 and extends to its outside. A spring 906 is fixed to one side wall of the tooth frame 903, and the other end of the spring 906 is fixedly connected to the inner wall of the hollow plate 6. When the template 8 needs to be replaced, it is only necessary to pull the moving rod 905 on one side. When one of the moving rods 905 moves, it will drive one of the tooth frames 903 to move. With the cooperation of the gear 902, the other tooth frame 903 can be driven to move in the opposite direction at the same time, and the movement of the tooth frame 903 will drive the limit block 904 to move. Therefore, after the restriction on the template 8 is released, it can be removed and replaced. During installation, it is only necessary to place the template 8 and press it. At this time, one end of the template 8 will be clamped under the limit block 904, thereby fixing the template 8.

When in use, the compressed air pipeline can be connected and fixed to the air inlet pipe 1303 through a hose. When the air blowing plate 1302 is rotated to the top of the template 8, the third hydraulic cylinder 1301 is started to drive the air blowing plate 1302 to move downward. At this time, the excess sand remaining on the template 8 and the hollow plate 6 can be automatically blown into the inside of the guide bucket 1304, so that there is no need for manual air blowing operation, and it is convenient to collect the excess sand after blowing.

[0028] like Figure 2As shown, in some embodiments, the rotating mechanism 14 includes a guide seat 1401 fixed on the top of the base 1, the top of the guide seat 1401 is rotatably connected to the support shaft 1402 through a bearing, the annular rail fixed on the top of the base 1 is internally rotatably connected to the rotating frame 1403, the top of the rotating frame 1403 is fixedly connected to the bottom of the top plate 10, and the top of the support shaft 1402 is fixedly connected to the rotating frame 1403.
