Abstract
The utility model discloses a kind of cross-head, cross-head structure is double-layer channel, comprise the mouth mould, mouth die holder, pressure ring, the cooling and shaping water jacket that are linked in sequence successively, core, handpiece body and connector, mouth mould is placed in a mouthful die holder, pressure ring is surrounded with around mouth die holder, handpiece body surface is furnished with runner, and be furnished with air blowing runner between runner, handpiece body both sides are provided with adjustment screw, handpiece body end is provided with connector, and head is connected with extruder Hafu-type mode.The utility model provides a kind of soon shaping, and more efficiency, has the cross-head of steady extruding feature.
Description
technical field:
The utility model relates to extrudes manufacture field, soon shaping more specifically to one, more stable, more the cross-head of efficiency.
background technology:
cross-head is as extrusion molding apparatus, how its version just determines its function, traditional cross-head complex structure, and inner cavity surface is coarse, make plastic melt be difficult to extrude smoothly, be generally only furnished with single channel even without runner, this makes the quality of goods greatly reduce, and traditional die heating and cooling aspect are difficult to improve process, problem to be solved in the utility model that Here it is.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of practical cross-head is provided, handpiece structure is double-current layer road, air blowing runner is furnished with between runner, head front end is provided with cooling and shaping water jacket, cooling water forms circulation waterway in head, and head adopts inside and outside electrical heating.
Technology solution of the present utility model is as follows:
A kind of cross-head, comprise the mouth mould, mouth die holder, pressure ring, the cooling and shaping water jacket that are linked in sequence successively, core, handpiece body and connector, mouth mould is placed in a mouthful die holder, pressure ring is surrounded with around mouth die holder, handpiece body surface is furnished with runner, and handpiece body both sides are provided with adjustment screw, and handpiece body end is provided with connector.
Described cross-head structure is double-layer channel.
Air blowing runner is furnished with between described runner.
The beneficial effects of the utility model are:
1, handpiece structure is double-layer channel, is furnished with air blowing runner between runner, ensures that plastic melt uniform and stable flowing in head is extruded smoothly.
2, the Transformed area of head is even, avoids dead angle, groove etc.
3, head has enough Rigidity and strengths, simple and compact for structure, is closely connected with machine barrel, easy to loading and unloading, easily processes, easy to operate.
4, Die Design becomes symmetric shape simultaneously, ensure that and is heated evenly.
5, flow channel size design is reasonable, controls shaping length, thus ensures cross sectional shape, ensure that the quality of goods.
accompanying drawing illustrates:
Fig. 1 is schematic perspective view of the present utility model;
In figure: 1, mouth mould; 2, pressure ring; 3, cooling and shaping water jacket; 4, handpiece body; 5, adjustment screw; 6, connector; 7, runner; 8, air blowing runner; 9, core.
detailed description of the invention:
6, embodiment: as shown in Figure 1, a kind of cross-head, handpiece structure is double-layer channel, comprises the mouth mould 1, mouth die holder, pressure ring 2, the cooling and shaping water jacket 3 that are linked in sequence successively, core 9, handpiece body 4 and connector 6, mouth mould 1 is placed in a mouthful die holder, be surrounded with pressure ring 2 around mouth die holder, handpiece body 4 surface is furnished with runner 7, is furnished with air blowing runner 8 between runner 7, handpiece body 4 both sides are provided with adjustment screw 5, and handpiece body 4 end is provided with connector 6.Handpiece structure is double-layer channel, is furnished with air blowing runner between runner, ensures that plastic melt uniform and stable flowing in head is extruded smoothly.
The Transformed area of head is even, avoids dead angle, groove etc.Head has enough Rigidity and strengths, simple and compact for structure, is closely connected with machine barrel, easy to loading and unloading, easily processes, easy to operate.Die Design becomes symmetric shape simultaneously, ensure that and is heated evenly.Flow channel size design is reasonable, controls shaping length, thus ensures cross sectional shape, ensure that the quality of goods.
