Abstract
The utility model relates to an insulation extruding machine head for cable cores, comprising an outer mold sleeve, an inner mold shuttle, and a machine head seat. The machine head seat is provided with an injection molding hole communicated with a cavity on the front part of the machine head seat. The cavity comprises a pressure equalizing sleeve, an outer mold seat, and an outer mold. The interior of the inner mold shuttle is provided with a hole through which the cable core can be threaded through, and the hole and an inner mold hole are homocentric. The front end of the inner mold is extended into the trumpet hole of the outer mold, and the top of the trumpet hole is provided with a line-forming hole. The utility model is characterized in that the rear part of the inner mold shuttle is provided with the eccentric adjustable mechanism of the inner mold and the outer mold, and the mechanism comprises the pressure equalizing sleeve and a regulating screw; the eccentricity can be adjusted in one step through an improved machine head; the outer mold and the inner mold can be matched in the 360 DEG direction.
Description
The utility model relates to the insulating exruded machine head of a kind of cable stamen line.
In cable was produced, the insulating exruded machine head of cable stamen line that generally adopts mainly was made of outer die casing, internal mold shuttle and headstock at present.One injecting hole is arranged on the headstock.Injecting hole communicates with the cavity of headstock front portion.One hole that the stamen line is passed is arranged in the internal mold shuttle, and nib is concentric in this Kong Yingyu.The internal mold front end stretches in the conical bore of external mold.The top of conical bore has one to become the line hole with the lead of being produced is corresponding.Lead stamen line passes from the hole of internal mold shuttle, passes from become the line hole.
Between the outer die casing of this head and the support be connected and the internal mold shuttle can not be tightened with being threaded of support so that adjust the concentricity of external mold and internal mold shuttle.This structure can be loosening in head work, causes that the concentricity volume of external mold and internal mold is poor, causes the off-centre of lead stamen line.On the other hand, this machine is in when work, inlet wire and internal mold off-centre, and internal mold weares and teares easily, and lack useful life.In addition, the one-tenth line angle degree of this machine, promptly conical bore drift angle angle big (30 degree) is restricted the plastics kind of selecting for use.
The purpose of this utility model is can keep internal mold and external mold concentricity at the problems referred to above design is a kind of, and the head that can adjust as required.
The utility model comprises outer die casing, internal mold shuttle and head.Injecting hole is arranged on the headstock.Injecting hole communicates with the cavity of headstock front portion.This cavity is to be made of equal gland, outer mould base, external mold.Plastics become equal pressure condition herein.The blow pressure that goes out of die orifice can be by the front and back position adjusting of internal mold shuttle.One hole that the stamen line is passed is arranged in the internal mold shuttle, and this hole is concentric with interior nib.The front portion of internal mold is stretched in the horn mouth of external mold, bell-mouthedly anterior becomes between the line angle 8-10 degree, and bell-mouthed top has one to become the line hole with the diameter of wire of being produced is corresponding.The eccentric adjusting mechanism of internal mold and external mold is equipped with at the rear portion of internal mold shuttle.The preceding die head and the back die head of high-abrasive material system is equipped with at the rear portion of the front portion of internal mold and internal mold shuttle respectively.
The insulating exruded machine head of cable stamen line can disposable adjusting off-centre after above-mentioned improvement.External mold, internal mold can 360 degree direction assemblings.The axial distance of internal mold and outer intermode can be regulated by mobile internal mold shuttle.By the concentricity of four tuningout heart screw adjusted internal molds and external mold, guarantee the uniform pressure of head die orifice simultaneously by equal gland.
Description of drawings.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the end view of Fig. 1.
Below in conjunction with accompanying drawing the utility model is elaborated.
As can be seen from the figure, internal mold shuttle 3 passes from headstock 4, and the front portion of internal mold shuttle is a conical internal mold 5, and the front portion of internal mold is the die head 9 with carbide alloy system.The front end of internal mold stretches in the horn mouth of external mold 6.The adjustment of internal mold shuttle can be rotated in both gaps.The horn mouth of external mold is made of 3 sections taper seats.The one-tenth line angle of front end is 9 degree, seamlessly transits between face and the face.External mold is fastened on the headstock by outer die casing 7.The alignment ring 1 that can arbitrarily load and unload is equipped with at internal mold shuttle rear portion, and a carbide alloy die head 11 is housed in the alignment ring.The rear portion of internal mold shuttle is clamped by four adjustment screw 2 that are installed on the equal gland.The off-centre of internal mold shuttle and external mold can be by the adjustment screw adjustment.When using the utility model head, should be earlier according to employed insulation raw material, as polyvinyl chloride, the front and back position of the thickness adjusted internal mold shuttle of insulating barriers such as polyethylene is to change the blow pressure that of die orifice.Adjust the concentricity of internal mold and external mold then.
This head can unload outer die casing 7 as required and change interior outer mold.External mold, outer mould base 8 can be fastened on the support by outer die casing, and can guarantee the concentricity that external mold and headstock go out to mould.Outer die casing is equipped with Electrothermal ring and keeps the interior plastics temperature (not drawing among the figure) of head.
