The specific embodiment
The present invention includes once filling adjusting mechanism, secondary filling adjusting mechanism ..., n filling adjusting mechanism, powder feeding mechanism and die cavity mechanism; Said primary filling guiding mechanism comprises primary filling adjustment motor; Primary filling adjustment motor connects primary filling through transmission mechanism and adjusts spacing screw rod, and primary filling is adjusted spacing screw rod bottom and established the primary filling limited roller; Said secondary filling adjusting mechanism comprises secondary filling adjustment motor, and secondary filling adjustment motor connects the secondary filling through transmission mechanism and adjusts spacing screw rod, and the secondary filling is adjusted spacing screw rod bottom and established secondary filling limited roller; Said n filling adjusting mechanism comprises n filling adjustment motor, and n filling adjustment motor connects n filling through transmission mechanism and adjusts spacing screw rod, and n filling adjusted spacing screw rod bottom and established the filling limited roller n time; Said once adjust spacing screw rod, secondary adjust spacing screw rod ..., n the spacing screw rod of adjustment rise on lengthwise position successively; Said die cavity mechanism is arranged on the bottom of powder feeding mechanism; Die cavity mechanism bottom connects reset cylinder through a lifters; Reset cylinder top establish successively the demoulding swing arm of going up and down, secondary demoulding swing arm with the corresponding restriction lifters of each filling adjusting mechanism ..., n-1 demoulding swing arm, each demoulding swing arm all can appear the locking or movable two states.
The spacing piston of filling that said each demoulding swing arm top is established driving cylinder respectively and driven by driving cylinder, the firm driving direction of said driving is variable.
The present invention carries out according to the following steps:
1) at first require to confirm the depth of fill of each section powder according to goods, then through primary filling guiding mechanism, secondary filling adjusting mechanism ..., n filling adjusting mechanism adjust the position that spacing screw rod is adjusted in each filling; The position of each demoulding swing arm is confirmed in the position of adjusting spacing screw rod according to each filling then; Promptly the corresponding primary filling in the position of a demoulding swing arm adjust spacing screw rod the position ..., n-1 demoulding swing arm corresponding this filling of n-1 in position adjust the position of spacing screw rod, and with each demoulding swing arm locking;
2) die cavity mechanism moves upward under the drive of reset cylinder, stops when primary filling is adjusted spacing screw rod until running into, and primary filling finishes;
3) remove a demoulding swing arm, die cavity mechanism continues to move upward under the drive of reset cylinder, stops the secondary sand off up to running into when spacing screw rod is adjusted in the secondary filling;
4) repeat 3) step, until n sand off;
5) after the sand off, on sweep away row compacting and make product molding, the back demoulding makes.
Come to set forth in detail the course of work of the present invention with secondary feeding, secondary filling below: 1) the present invention at first requires to confirm the depth of fill of one, two powder according to goods; Thereby adjust the position that spacing screw rod is adjusted in each filling through first and second time filling adjusting mechanism, and set the action of each gas, liquid, electric system; The airdraulic actuator epicoele normal open gas of the depth of fill of control one, two powder; So that the spacing piston of filling stops the come-up of demoulding swing arm at face bottom; Thereby the come-up of die face in the control; The realization filling needs, and the power that the pressure of gas-liquid conversion cylinder cylinder of the present invention should make the spacing piston of filling produce is slightly larger than the power that makes progress that reset cylinder produces;
2) after the machine demoulding began, along with going deep into of the demoulding, the feeding swing arm drove the material boots and moves forward under demoulding action of cam; The demoulding finishes; Goods are deviate from die cavity fully; This moment, feeding cam went to isometrical section 1-2 from 6, and expected that boots release goods and material boots chamber directly over die cavity this moment, and the filling first time begins; And middle die face is moved upward under the promotion of reset cylinder and runs into primary filling and adjust spacing screw rod and stop, and filling for the first time, feeding finish;
3) magnetic valve of control gas-liquid conversion cylinder commutates under the control of PLC; The spacing piston constraint relief of filling moves up; Demoulding swing arm moves up immediately, and middle die face moves up under the promotion of reset cylinder and stops until running into the secondary filling to adjust spacing screw rod; This moment, feeding cam went to 3-4 from isometrical section 1-2, and same feeding material boots chamber rollback carries out the feeding filling to middle die face die cavity top, the sand off of feeding for the second time;
4) last feeding cam is converted to isometrical section 5-6 from isometrical section 3-4, and the material boots can fall back on rear, on sweep away row and carry out pressed ware, the machine run demoulding again, feeding, filling, completion once circulate.
More than be the forming method of two layers of pulverulent product, the forming method principle of multilayer pulverulent product is the same.
