Abstract
Description
Technical Field
[0001] The utility model relates to a molding machine with a sand box pushing mechanism, belonging to the technical field of molding machines. Background Art
[0002] The molding machine is a casting equipment used to make sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box, compacting the molding sand, and making the loose molding sand in the sand box compact by different methods such as vibration, compaction, vibration pressure, and shot pressure, so that the sand mold has the necessary strength during transportation and pouring, and demolding, using different mechanisms to take the pattern out of the compacted sand mold.
[0003] However, the sand box on the existing molding machine is fixed above the molding mold. When the workers take out the mold and place the mold core after the molding mold is demolded, too much working space is occupied by the sand box on the upper end, which makes the operating space smaller when the workers take out the mold and place the mold core, increasing the difficulty of taking out the mold and placing the mold core. Sometimes the user will collide with the sand box during operation. In view of the above shortcomings, the utility model proposes a molding machine with a sand box pushing mechanism.

[0006] A further improvement is that the pushing frame includes a pushing cross frame and an operating opening opened at the front end of the left side of the pushing cross frame, a displacement groove of an extrusion feeding mechanism is opened laterally on the right side of the operating opening, and a plurality of supporting feet are arranged at intervals on the bottom surface of the pushing cross frame.

The material hose 35 is connected. When the pushing mechanism 32 pushes the extrusion feeding mechanism 34 to move to the left, the extrusion feeding mechanism 34 extends downward to abut against the top surface of the molding die set 2. The pushing frame 31 includes a pushing cross frame 311, an operation opening 312 opened at the front end of the left side of the pushing cross frame 311, and an extrusion feeding mechanism displacement groove 313 is opened horizontally on the right side of the operation opening 312. A plurality of legs 314 are arranged at intervals on the bottom surface of the pushing cross frame 311. The pushing mechanism 32 includes a pushing seat 321, a dragging block 32 arranged in the middle of the bottom surface of the pushing seat 321, and a plurality of support legs 314 are arranged on the bottom surface of the pushing seat 321. 2. A screw rod 323 is transversely threadedly connected to the drag block 322, and a motor 324 is transmission-connected to the right end of the screw rod 323. Two slide seats 325 are respectively arranged on the front and rear sides of the bottom of the push seat 321. A slide rail 326 is sleeved between the two transverse slide seats 325. A crossbeam 327 is transversely arranged on the left side of the push seat 321. The sand box group 33 includes a sand box 331 and a spiral agitator 332 vertically arranged in the cavity of the sand box 331. A feed port 333 is opened on the right side of the top surface of the sand box 331. A sand box discharge pipe 334 is connected to the bottom surface of the sand box 331. The extrusion feeding mechanism 34 includes a telescope 341, a lifting frame 342 arranged on the bottom surface of the telescope 341, and a plurality of sliders 343 arranged on the left and right sides of the lifting frame 342. A stabilizing slide 344 is vertically sleeved on the outside of each slider 343. A screw conveyor 345 is vertically arranged in the cavity of the lifting frame 342.

The right side feed port of the screw conveyor 345 is connected to the lower end of the sand box discharge pipe 334 through a feed hose 35.
[0020] Working principle:
[0021] When the extrusion feeding mechanism 34 spirally squeezes the raw materials in the sand box group 33 into the molding die group 2 through the feeding hose 35, the spiral agitator 332 will cooperate with the feeding to prevent the raw materials in the sand box 331 from being blocked. Then the automatic solenoid valve 347 is closed first to prevent sand leakage. Then the telescopic device 341 is retracted, and the discharge pipe 346 at the lower end of the screw conveyor 345 is disconnected from the top surface of the molding die group 2 through the lifting frame 342. Then the motor 324 on the pushing mechanism 32 rotates, and the screw rod 323 is used to push the material into the mold. Pull the drag block 322 to the right, and through the push seat 321, each slide seat 325 slides to the right on the slide rail 326, thereby driving the sand box group 33 and the extrusion feeding mechanism 34 to move to the right. At this time, the lifting frame 342 on the extrusion feeding mechanism 34 will slide to the right in the extrusion feeding mechanism displacement groove 313, so that the space of the working opening 312 is completely opened. At this time, the staff can remove the mold of the molded part after the mold is opened by the molding mold group 2 and re-place the mold core in the relatively open space at the working opening 312.
