Description
Technical field
This utility model belongs to the equipment manufacturing dry ice, is specifically related to a kind of dry-ice machine die head protection device.
Background technology
At present in dry ice manufacture process, liquid CO2By liquid CO2Storage tank enters liquid CO2Pipeline, enters back into dry ice extrusion moulding chamber and is promoted after mould cylinder piston extrudes by hydraulic jack, and dry ice is from die head extrusion molding.Existing dry-ice machine in dry ice manufacture process, dry ice extruded intracavity liquid CO2Run into air to freeze immediately, easily block the air-vent of the extruded intracavity of dry ice, the nut of the screw end of fixing mould cylinder piston is easily broken in dry ice extrusion process and is come off, and falls in the middle of die head and piston, at hydraulic jack when ejecting forward, often result in die head to damage, and die head is expensive, it is accomplished by after damage changing, it is impossible to repair, not only have impact on production, and considerably increase cost.
Summary of the invention
The purpose of this utility model is to provide a kind of dry-ice machine die head protection device, and this die head protection device overcomes the deficiencies in the prior art, simple in construction; convenient and reliable; overcome cap nut to come off and the problem that causes die head to damage, it is ensured that the normal production of equipment, reduce cost.
For reaching above-mentioned purpose, this utility model one dry-ice machine die head protection device, including fixing the mould cylinder being connected with hydraulic jack, dry ice extrusion moulding chamber it is provided with in mould cylinder, left end at the extruded intracavity of dry ice is movably set with mould cylinder piston, right-hand member is provided with die head, it is characterized in that: the centre of described mould cylinder piston is provided with screw hole, screw is installed in screw hole, mould cylinder piston is fixed by the piston rod of screw with hydraulic jack, the inwall of the end screw hole of screw is provided with endoporus draw-in groove, the endoporus draw-in groove of screw hole is provided with endoporus snap ring, described endoporus snap ring is in order to block screw.
In technique scheme, this utility model has a following beneficial effect: first, overcomes the deficiencies in the prior art, and simple in construction is convenient and reliable；Second, owing to the dry ice of solidification easily blocks the air-vent of the extruded intracavity of dry ice, the nut of screw end is easily broken in dry ice extrusion process and is come off, when hydraulic jack ejects forward, the nut come off often results in die head and damages, this utility model is provided with endoporus snap ring on the inwall of the middle screw hole of mould cylinder piston, endoporus snap ring can block the nut come off effectively, the nut preventing fracture does not falls out in the middle of piston and die head, avoid the problem causing die head to damage owing to cap nut comes off, ensure that the normal production of equipment, reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of dry-ice machine die head protection device；
Fig. 2 is the mounting structure schematic diagram of endoporus snap ring in Fig. 1；
Fig. 3 is the structural representation of endoporus snap ring in this utility model a kind of dry-ice machine die head protection device.
Detailed description of the invention
With embodiment, this utility model one dry-ice machine die head protection device is described in further detail below in conjunction with the accompanying drawings.The accompanying drawing constituting the application is used for providing being further appreciated by of the present utility model, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.
By Fig. 1, Fig. 2, Fig. 3 is visible, a kind of dry-ice machine die head protection device of the present embodiment includes the mould cylinder 2 that be connected fixing with hydraulic jack 1, dry ice extrusion moulding chamber 3 it is provided with in mould cylinder 2, left end in dry ice extrusion moulding chamber 3 is movably set with mould cylinder piston 4, right-hand member is provided with die head 9, the centre of mould cylinder piston 4 is provided with screw hole 5, screw 6 is installed in screw hole 5, mould cylinder piston 4 is fixed with hydraulic jack 1 by screw 6, the inwall of the end screw hole 5 of screw 6 is provided with endoporus draw-in groove 7, the endoporus draw-in groove 7 of screw hole 5 is movably installed with endoporus snap ring 8, the present embodiment endoporus snap ring 8 can block the nut come off on screw 6 effectively, avoid the problem causing die head 9 to damage owing to cap nut comes off.
In the present embodiment, owing to the dry ice of solidification easily blocks the air-vent 10 in dry ice extrusion moulding chamber 3, produce negative pressure to be broken by the nut of screw 6 end when hydraulic cylinder piston rod and mould cylinder piston are to rollback, nut is made to drop in die head 9 and the centre of mould cylinder piston 4, the nut come off often results in die head 9 and damages when hydraulic jack ejects forward, the present embodiment is provided with endoporus snap ring 8 on the inwall of the middle screw hole 5 of mould cylinder piston 4, can effectively block the nut come off, avoid the problem causing die head to damage owing to cap nut comes off, ensure that the normal production of equipment, reduce cost.
The above; it it is only embodiment of the present utility model; not this utility model is imposed any restrictions, the change of every any simple modification, change and equivalent method above example made according to this utility model technical spirit, all still fall within the protection domain of technical solutions of the utility model.
