Abstract
The utility model relates to a wire coating machine head without regulating a mould, which is composed of a machine head casing, a front cover, a rear cover, an inner mould, an outer mould, a mould core and a cabling sleeve, wherein, the inner mould and the outer mould of the machine head are in a fixed coaxial position structure; troughs are uniformly distributed in an inner cavity of the front cover to cause the wire coating to be in concentric mode and has uniform thickness. The quality of the appearance luster of the wire is good, and the operation does not need to be adjusted. Thus, the utility model is suitable for manufacture of wire in large batch, can be matched with the homemade and the imported rubber and plastic extruders of various models, and is fitted with a special tool for gremoving scraps.
Description
The utility model belongs to system electric wire rubber, plastic coatings extruder head.
The rubber of electric wire or plastic coatings are finished by rubber or plastic extruders.General electric wire coating extruder uses 3 adjustment type heads, this head needs experienced operator to use the internal mold and the external mold of head coaxial with range estimation and the screw above the feel adjustment head shell, and start operation, cut off electric wire, electric wire cross section coating is looked in sight, and whether thickness comes evenly to determine that mode transfer is suitable.In operation, since mechanical oscillation, the influence of factors such as feeding pressure, flow, temperature, the interior external mold position of adjusting easily changes, and the result makes electric wire coating off-centre, produces waste product.Especially in production in enormous quantities, quality is wayward, and raw-material waste is very big.After the operation, salvage stores is set in the head, and hit with the sharp device of metals such as shovel, hammer and remove, 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 electric wire coating machine head of a kind of rubber, plastic extruders, improves electric wire and produces quality in enormous quantities.
The utility model is made up of head shell 1, protecgulum 2, external mold 3, internal mold 4, packing ring 5, core rod 6, bonnet 7, cabling cover 8, bearing 9, wherein, internal mold and external mold embed core rod for fixing coaxial position structure, internal mold rear end, and die core back end is embedded with bearing and is close to bonnet; The internal mold front end is close to by pad and external mold, and external mold is close to protecgulum, and protecgulum is connected by screw thread and head shell; Have certain clearance between internal mold and the external mold, interior die orifice has certain length apart from outer die orifice.Preceding cover cavity has uniform logical hopper 10, and logical hopper is more than 2, and according to the specification difference of head, groove can be established 3～6, evenly flows to internal mold and outer die clearance to keep melt.
During operation, electric wire extends to outside the machine through cabling cover, core rod, internal mold, external mold along axis direction; Have the melt rubber of certain pressure and temperature or circular cone inlet, core rod, the protecgulum of plastics process head shell simultaneously and lead to the gap between hopper, internal mold and the external mold, tight electric wire is covered uniformly in die orifice portion outside, protracts with electric wire.During shut-down operation, back out the cabling cover, change special-purpose nut, be screwed into except that the defective material instrument, remove defective material instrument front end and snap in bearing inner ring, back out protecgulum then, rotation removes the defective material instrument can be easy to remove defective material in the head.
The utility model has guaranteed that from structure the internal mold of head and external mold are in coaxial position all the time, each part has assembly relation closely, thereby guaranteed that the electric wire cross section is a concentric circles, the coating thickness uniformity, gloss appearance is good, need not adjust the position of internal mold and external mold, significantly improve product quality, reduce waste product.Save raw-material consumption, and versatility is good, can be supporting with rubber, the plastic extruders of domestic and international various models.
