Description

An automatic core-shooting and parting system for the production of gating risers

technical field

The invention relates to the technical field of core-shooting and core-making in sand casting, in particular to an automatic core-shooting and mold-parting system used for the production of gating risers.

Background technique

Mold core making is a way in precision casting production. The common hot box and cold box core making, because the sand core is first solidified in the mold after sand shooting, and then the sand core is separated, the separation difficulty is relatively low, so there are already corresponding automatic production equipment on the market. In the ordinary core shooting process, the sand core does not need to be solidified before the mold is divided, so the production efficiency is high, but the mold is difficult to separate. When the upper and lower molds are separated, it is necessary to ensure the parallelism of the two molds. Manual parting is used, requiring workers to have a high degree of technical proficiency. In addition, since the mold with sand cores weighs 40-50Kg, the weight is relatively heavy, and manual separation is very labor-intensive. In addition, there is a lot of dust in the production process, and the production environment is not suitable for manual operation.

The working process of an automatic core-shooting and parting system for the production of sprue risers provided in this embodiment is as follows:

First, after the upper mold 41 and the lower mold 42 are closed, they are placed on the mold positioning frame 14. When the mold 15 rotates to the automatic core shooting station 16, the mold 15 is just below the sand shooting cavity 22 of the core shooting machine. The hydraulic cylinder 111 drives the lifting ejector pin 110 to extend upwards, thereby moving the mold positioning frame 14 and the mold 15 upwards to the port of the sand shooting cavity 22. Under a certain pressure, the core shooter starts the sand shooting work, and the mold 15 can be The mold cavity is filled with resin sand to complete automatic sand shooting.

After the sand shooting is completed, the rotary shaft 12 rotates 90 degrees, and the mold 15 filled with resin sand arrives at the sand filling station 17, and the bottom of the sand core is filled up with manual assistance to complete the sand filling operation.

Then the rotary shaft 12 continues to rotate 90 degrees, and the mold 15 that has been filled with sand reaches the automatic mold splitting station 18, and enters the automatic mold splitting process. The mold 15 is turned over, the mold 42 is pulled out, and the lower mold 42 is turned over and put back to the automatic mold splitting process. On the mold station 18, put the net plate 37, the net plate 37 and the upper mold 41 are overturned, separate the upper mold 41 and the upper mold 41 is moved back to the automatic mold splitting station 18 and the lower mold 42 tool 15 clamping. The specific process is as follows: driven by the horizontal guide rail 32 and the vertical guide rail 33, the two flipping claws 34 approach the mold 15 on the automatic mold splitting station 18 respectively. Driven by the cylinder 310, the upper splint 341 of each flipping handle The upper and lower sides of the mold handle 43 are respectively clamped with the lower clamping plate 342, thereby clamping the upper mold 41 and the lower mold 42 to lift together, and driven by the turning motor 39, the upper mold 41 and the lower mold 42 are turned up and down 180 degrees together , then the upper mold 41 and the lower mold 42 are placed on the sand core delivery platform 312, and the overturning claws 34 are released. At this time, the upper mold 41 is at the bottom and the lower mold 42 is at the top. Then the lower mold 42 positioned at the top is grabbed separately again by the overturning claw 34, and the lower mold 42 is lifted vertically to realize the separation of the lower mold 42, and then the separated lower mold 42 is rotated 180 degrees up and down and then placed on the automatic mold parting tool. Position 18 of the mold positioning frame 14. Then under the drive of the horizontal guide rail 32, the sucker claws 35 arrive at the top of the screen plate support platform 311, the suction cup claws 35 move down to grab the screen plate 37, and the screen plate 37 is placed on the inverted upper mold 41, and then the two A turning claw 34 clamps the mold handle 43 of the upper mold 41 and the screen plate 37 together, lifts and rotates 180 degrees up and down, and then puts it on the sand core delivery platform 312 again. superior. Then, the patrix 41 located above is individually grasped again by the overturning claw 34, and the patrix 41 is lifted vertically to realize the separation of the patrix 41, and then the patrix 41 after separation is placed on the lower part of the automatic mold splitting station 18. On the mold 42, the automatic parting work is finished so far, and the sand core falls on the screen plate 37, and can be sent to the end together along the conveying guide rail 313, for manual or machine to take away and dry.

The re-closed mold 15 will move to the cleaning mold cavity station 19 when the rotary shaft 12 rotates 90 degrees again, and the mold cavity can be cleaned regularly manually.
