Abstract
The utility model relates to a rubber and plastic extruding machine head for the protective layers of electric lines, comprising a machine head casing, an inner mold, an outer mold, a mold core, etc. The inner mold and the outer mold of the machine head do not need to be adjusted, and are arranged on a coaxial position all the time; accordingly, the protective layers of the electric lines are homocentric, and the thickness are consistent. The machine head can be matched with native and foreign rubber and plastic extruding machines having various types, and the machine head is matched with a purpose-made tool for removing leftover material.
Description
The utility model belongs to makes electric wire rubber, plastic extruder head.
The rubber of electric wire or plastic sheath are finished by rubber, plastic extruder.For a long time, rubber, plastic extruder use 3 adjustment type heads, this head needs experienced operating personnel to adjust screw outside the head shell with range estimation and feel to make the internal mold of head and external mold coaxial, and start operation, cut off electric wire, see the cross section sheath of inspection electric wire and whether judge with one heart that the thickness of electric wire sheath is even.In operation, because the influence of factors such as mechanical oscillation, feeding pressure, flow, temperature, the internal mold position of adjusting easily changes.The result makes electric wire sheath off-centre, produces waste product.Especially in production in enormous quantities, raw-material waste is very big.After the operation, when removing salvage stores, hit with the sharp device of metals such as shovel, hammer, time and effort consuming, fragile head further influences the electric wire quality.
The purpose of this utility model is to provide the not mode transfer head of a kind of rubber, plastic extruder.
The utility model has guaranteed that from structure the internal mold of head and external mold are in coaxial position all the time, the coaxial position structure of this internal mold and external mold, by the spatial geometric shape of internal mold and external mold and other part closely assembly relation determine, thereby guaranteed the concentric of electric wire sheath, the thickness uniformity.Keep certain clearance between internal mold and the external mold, in the die orifice portion, interior die orifice has certain length apart from outer die orifice place to interior die orifice outside, effectively packs tightly electric wire with assurance melt rubber or plastics.Preceding cover cavity has the logical hopper of evenly arranging more than two, makes melt rubber or plastics more even at the internal mold oral area, further improves the quality of electric wire sheath.Shown in its detailed structure Fig. 1, it is made up of head shell (1), protecgulum (2), external mold (3), internal mold (4), packing ring (5), movement (6), bonnet (7), cabling cover (8), bearing (9).During operation, electric wire extends to outside the machine through cabling cover (8), movement (6), internal mold (4), external mold (3) along axis direction; Simultaneously, have the melt rubber of certain pressure and temperature or plastics and lead to gap between hopper, internal mold (4) and the external mold (3) through the inner chamber of the circular cone inlet of head shells (1), core rod (6), protecgulum (2), pack tightly electric wire uniformly at external mold (3) oral area, protract with electric wire.During shut-down operation, back out cabling cover (8), change special-purpose nut, be screwed into specific purpose tool shown in Figure 6, the front end of specific purpose tool snaps in bearing (9) inner ring, backs out protecgulum (2) then, rotates specific purpose tool and can remove the interior defective material of head.
The utility model is rational in infrastructure, easy and simple to handle, need not adjust the position of internal mold, the electric wire sheath thickness of output is even, gloss appearance is good, has significantly improved product quality, has reduced waste product, saves raw-material consumption, and versatility is good, can be supporting with rubber, the plastic extruder of domestic and international various models.

Fig. 2 is a right view of the present utility model.
Fig. 3 is the protecgulum cutaway view.
Fig. 4 is the protecgulum left view.
Fig. 5 is the core rod cutaway view.
Fig. 6 removes defective material instrument schematic diagram.
In Fig. 1, head shell (1), protecgulum (2), external mold (3), internal mold (4), packing ring (5), movement (6), bonnet (7), cabling cover (8), bearing (9).
In Fig. 3, protecgulum (2), logical hopper (10).Among Fig. 4, protecgulum (2), logical hopper (10).
Further specify the utility model below in conjunction with accompanying drawing for an embodiment.
Among Fig. 1, protecgulum (2) is by screw thread and fastening connection of head shell (1).Slave head capsule (1) left side is along axis pack into external mold (3), packing ring (5), internal mold (4), movement (6), bearing (9), bonnet (7), cabling cover (8).Wherein, external mold (3) is a T10A carbon steel, and internal mold (4) is a Hardmetal materials, and other part is No. 45 carbon steel, and bearing is selected single-row centripetal bearing for use No. 20, and be equipped with except that the defective material specific purpose tool shown in Figure 6.
Claims (3)
1, a kind of rubber of electric wire sheath, plastic extruder head are made up of head shell, protecgulum, bonnet, external mold, internal mold, movement, cabling cover, it is characterized in that: the coaxial position structure of a, internal mold and external mold, the uniform logical hopper of cover cavity before the b.
2, according to the described head of claim 1, it is characterized in that the coaxial position structure of described internal mold and external mold, between internal mold and external mold, keep certain clearance.
3, according to claim 1,2 described heads, in the die orifice portion, interior die orifice has a length apart from outer die orifice to die orifice outside in it is characterized in that.
