Description
Technical Field
The utility model relates to the technical field of mold, concretely relates to mold box.
Background
Core shooters are widely used in recent years, and high molding wages can be saved by using the core shooter for molding. Because the waste of a casting head can be reduced by stacking and pouring a plurality of boxes, the collapsibility of the coated sand after pouring is good, and the sand cleaning is facilitated. The core shooter has high production efficiency and accurate size of the sand mold, and can properly reduce the processing amount; simple operation and high casting yield. More foundries prefer to use core shooter models.
The injection and compression molding machine is a molding machine that uses compressed air to uniformly inject molding sand into a flask for pre-compacting, and then applies pressure to compact the molding sand. The common injection molding machine has a vertical parting flaskless injection molding machine and a horizontal parting flaskless injection molding machine. The vertical parting flaskless injection molding machine does not need a sand box for molding, molding sand is directly injected into a molding chamber of the mold box, the manufactured sand mold has high dimensional precision, mold cavities are arranged on two sides of the mold box, the production efficiency is high, core setting is difficult, and the requirement on the quality of the molding sand is strict.
Therefore, how to upgrade the existing mold box to overcome the above problems is a problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lower core is efficient, ejecting stable in structure's mould case.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a mold box, characterized in that: including last core box, lower core box and die carrier, lower core box set up in the die carrier top, go up the core box with lower core box cooperation is connected, it is provided with the sand shooting subassembly to go up the core box top, the inside roof that is provided with down of die carrier, be provided with jib and ejector pin on the roof down, roof sliding connection in down the jib, the ejector pin upwards extends inside the lower core box, the roof extends the fixed plate to both sides down, the sliding tray has been seted up to the die carrier both sides, the fixed plate slide set up in the sliding tray, the die carrier bottom is provided with the cylinder, cylinder control the roof goes up and down.
Specifically, the sand shooting assembly comprises an air blowing plate, a sand shooting plate and a shooting nozzle, one end of the shooting nozzle is connected with the air blowing plate, the other end of the shooting nozzle penetrates through the sand shooting plate, and a positioning pin is arranged between the upper core box and the sand shooting plate.
As an improvement, a lower top column is arranged below the lower top plate, a through hole is formed in the bottom of the die carrier, and when the lower top plate descends, the lower top column can penetrate through the through hole.
As an improvement, a lower core box limiting column is arranged on the lower top plate, and when the lower top plate rises upwards, the lower core box limiting column can extend into the lower core box.
As an improvement, two sides of the upper core box are provided with carrying grooves.
Compared with the prior art, the utility model has the advantages of: the stability of ejector pin when this mould case is for preventing lower core, strengthens the structure of roof down, makes its and die carrier sliding connection, ensures that roof down is difficult for the skew at the core in-process that rises and descends, adds the cylinder in the die carrier and is used for carrying out the core to easy ejecting product, need not other devices, to the great product of volume, relies on the cylinder alone and can't realize the ejector pin, can utilize the lower fore-set of roof below installation down, uses outside machinery to realize the ejector pin.
