无箱造型机出现错型错误的原因主要有两个:
There are two main reasons for the incorrect shape of the unboxing molding machine:
一方面，它受到造型机本身精度的影响，同时也受到其配套工艺设备或其辅助设备的影响。建模、板放置不均匀时,沙子移错,板本身设计和安装错位,盒子的内壁是坚持砂块,和沙子堆积是错误的和许多其他因素的原因错误类型的问题。知道了错误类型的原因，就应该尽量避免。
On the one hand, it is influenced by the accuracy of the molding machine itself, as well as by its supporting process equipment or auxiliary equipment. When modeling and uneven placement of boards, sand is moved incorrectly, the design and installation of the board itself are misaligned, the inner wall of the box is stuck with sand blocks, and sand accumulation is incorrect due to many other factors. Knowing the reasons for the wrong type should be avoided as much as possible.
1. 锥型定位销粘有砂块
1. The conical positioning pin is stuck with sand blocks
自动免箱造型机有特殊设计，是圆锥定位销定位，这种方式方便更换模板。模板不需要固定。更换模板只需将使用过的模板提起，更换新的模板，扩大支架。更改模板非常快。
The automatic box free molding machine has a special design, which is a conical positioning pin positioning method, which is convenient for replacing templates. The template does not need to be fixed. To replace the template, simply lift the used template, replace it with a new template, and expand the bracket. Changing templates is very fast.
2.推型过快
2. Pushing too fast
在造型过程中,完成后箱模型,首先脱槽油缸驱动脱情况下董事会完成关闭对话框形砂轮胎从辅助砂箱,砂型板回到原位,此时完成后无箱造型机盒子形状的砂轮胎需要从造型我转移到铸件的浇注位置行走部分,如果推箱油缸的速度通过较快，推箱板到箱砂轮胎就会和箱砂轮胎晃动而前进。
During the modeling process, the rear box model is completed. Firstly, when the slotting oil cylinder drives the detachment, the board of directors closes the dialog box for the sand tire to return to its original position from the auxiliary sand box and the sand mold plate. At this time, the sand tire in the shape of the box of the box less molding machine needs to be transferred from the molding position to the pouring position of the casting. If the speed of the pushing oil cylinder passes quickly, the pushing box plate to the box sand tire will shake and move forward with the box sand tire.
3.箱体内壁不干净
3. The inner wall of the box is not clean
有沙块粘在上面无箱造型机厂家建议，从成品砂胎上取下后，要用清洁剂清洗干净。但长期使用后，刷子上的清洁剂会老化而形成清洗不洁，导致箱体内壁仍有砂球，在箱体上粘上砂子轮胎。当上时，这些多余的砂团就会形成砂胎移动，从而使用砂错位。
The manufacturer of the unboxing molding machine suggests that after removing the sand block from the finished sand tire, it should be cleaned with a cleaning agent. But after long-term use, the cleaning agent on the brush will age and form unclean cleaning, resulting in sand balls still on the inner wall of the box and sand tires sticking to the box. When used, these excess sand masses will form sand tire movement, resulting in the use of sand misalignment.
4. 起模不均匀
4. Uneven mold lifting
将上箱砂胎倾斜模板放在吊模架上。外观完成后，模板拆下时，起升模具支点在起升模具架上不成度线，起升模具的速度不同造成起升模具的高度不同。放箱子的时候，箱子会推着箱子上的沙胎移动。其实这种情况和上面的砂块箱清洗不干净是一样的，其结果就是砂胎在上下箱的位置错位了。
Place the inclined template of the upper box sand tire on the suspension frame. After the appearance is completed, when the template is removed, the fulcrum of the lifting mold does not form a straight line on the lifting mold frame, and the different speeds of the lifting mold result in different heights of the lifting mold. When placing the box, it will push the sand tire on the box. In fact, this situation is the same as the incomplete cleaning of the sand block box above, and the result is that the sand tire is misaligned in the upper and lower boxes.
