Description
Technical field
The utility model relates to injection molding machine technical fields, in particular to a kind of nozzle guard.
Background technique
Currently, nozzle guard is provided on injection molding machine, to stop the high temperature melt that may be sputtered when injection, from
And it guarantees personal safety.Meanwhile injection molding machine is being expected clearly, is replacing mold, replacement nozzle or progress equipment without positioning ring
Maintenance when, it is also desirable to protected with nozzle guard.Currently, being had in the market using more nozzle guard
Four kinds: the first, nozzle guard is directly anchored on solid plate, and the metal plate that nozzle guard covers on injection molding machine fore side passes through
Hinge is fabricated to opening door structure；Second, circular hole is opened inside nozzle guard cover equipped with sliding block, sliding block is along being perpendicularly fixed at cover half
Two guide posts on plate realize sliding and folding, and sliding equipment is also possible to idler wheel, linear bearing or built-in ball；The third,
It is fixed with gib block in melten gel barrel cover, matched sliding block is housed inside nozzle guard cover, nozzle guard cover can be in melten gel barrel cover
On reciprocatingly slide realization folding；4th kind, shield fixed plate is installed on solid plate, is passed through between fixed plate and movable cover
Damping hinge or the connection of undamped formula hinge, realize shield along the rotary motion of the direction of rotation of hinge.
There are the following problems for the first above-mentioned structure: a face metal plate of nozzle guard cover is fabricated to opening door by hinge
Structure, when operation, need to open protective door, since protection hinge needs enough installation spaces, it may appear that and avoiding space is insufficient,
The problems such as observation is inconvenient.
There are the following problems for second above-mentioned of structure: two guide posts being perpendicularly fixed on solid plate belong to cantilever beam knot
Structure needs enough length and rigidity, the spray increased especially with type to merge out enough operations or maintenance space
The rigidity in the space of mouth shield volume and operation or maintenance, cantilever beam guide pillar structure must be promoted sharply, and structure is caused to lack
Weary dexterity, cost also rise rapidly therewith；In addition such nozzle guard shade assembly is more, assembles time-consuming and laborious.
There are the following problems for the third above-mentioned structure: the move distance of nozzle guard cover and space requirement may be superimposed on molten
On packing element cover, it is similar to nested type mechanism, there are the structural advantages for minimizing movement parts space requirement, but due to being in rubber melting cylinder
It is moved on cover, therefore when replacing expects pipe group and its to require dismounting primary for nozzle guard cover when melten gel barrel cover, i.e. versatility and exchange
Property is very poor.
There are the following problems for the 4th kind of above-mentioned structure: shield realizes rotation by the reciprocating motion of damping hinge,
Advantage is that field of view increases, but since access times are more frequent, the shadow of the service life of hinge to entire protective cover
Space accounting is big when ringing the problem of existing very much, often will appear failure for a long time, and rotating, and is in addition applied to large-tonnage injection molding machine
When, be only hinged entire protecting cover, causes the rigidity of structure insufficient, cost also rises rapidly therewith.
