Abstract
The utility model relates to a metal wire sheath extrusion molding die, which comprises a plastic extrusion cavity, a low-air-pressure cavity and a silica gel ring, wherein a metal wire is extruded from and covered by a plastic sheath layer through the die; air pressure between the metal wire and the plastic sheath layer is lower than external atmosphere pressure; the problem that the plastic sheath layer settles down under the action of gravity is solved; and the plastic sheath layer can be tightly attached to the metal wire during cooling and hardening.
Description
Technical field
The utility model relates to technical field of mold, relates to a kind of metal wire rod sheath extruded mould or rather.
Background technology
In order to protect metal wire rod better, need extrude parcel plastic cement restrictive coating to metal wire rod, restrictive coating plastic material PVC or PE extrude through screw rod in parcel plastic cement restrictive coating process, utilize extruded mould equably attached to the surface of metal wire rod.Because the metal wire rod cross-sectional area is big; Can be when the plastic material PVC of fusion or PE adhere to because the effect generation sedimentation of gravity; The plastic cement restrictive coating thickening that causes the bottom surface, and near the plastic cement restrictive coating attenuation at top, the settlement action of gravity also can cause the adhesion effect variation of restrictive coating and metal wire rod simultaneously; Make foreskin under the effect of external force, produce with metal wire rod easily and separate, be unfavorable for the durability of metal wire rod.
This shows that above-mentioned existing metal wire rod sheath extruded mould still has many defectives, and demands urgently improving.
Because the defective that above-mentioned existing metal wire rod sheath extruded mould exists; The design people is based on being engaged in this type of product design manufacturing for many years; Long-pending have abundant practical experience and professional knowledge, actively studies innovation, in the hope of founding a kind of metal wire rod sheath extruded mould that improves molding structure; Can improve the molding structure of existing common metal wire rod sheath extruded mould, make it have more competitiveness.Through constantly research, design, and after studying sample and improvement repeatedly, found out the utility model of true tool practical value finally.
Summary of the invention
The utility model technical problem underlying to be solved is, overcomes the problem of the plastic cement restrictive coating generation sedimentation of existing metal wire rod sheath extruded mould existence.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.Metal wire rod sheath extruded mould according to the utility model proposes comprises plastics extruding cavity, low pressure chamber and silica gel circle, and the air pressure in low pressure chamber is that 1/10th of external atmosphere pressure arrives one of percentage.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before the thickness of described silica gel circle be 5 millimeters to 20 millimeters.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know by above technical scheme; The utility model can cause the air pressure between plastic cement restrictive coating and the metal wire rod to be lower than atmospheric pressure because the employing technique scheme is the low pressure chamber; Under the effect of draught head, the plastic cement external sheath layer receives a pressure, and direction is pointed to wire rod cross section symmetrical centre; The gravitational settling effect of plastic cement external sheath layer becomes not obvious, and the plastic cement external sheath layer is tightr with the combination of metal wire rod in the setting and hardening process.
In sum, the utility model really belongs to innovation on the kenel of space, and has the multinomial effect of enhancement than existing product, and simple in structure, is suitable for practicality, has the extensive value of industry.It is in limited field, technical development space; No matter structurally or bigger improvement all arranged on the function; And have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really; Thereby being suitable for practicality more, really is the new design of a novelty, progress, practicality.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technological means of understanding the utility model; And can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the utility model metal wire rod sheath extruded mould.
Among the figure, metal wire rod 1, plastics extruding cavity 2, low pressure chamber 3, silica gel circle 4, bleeding point 5.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also shown in Figure 1; This practical metal wire rod sheath extruded mould; Comprise plastics extruding cavity 2, low pressure chamber 3 and silica gel circle 4, metal wire rod 1 passes extruded mould, and it is that 1/10th of external atmosphere pressure arrives one of percentage that aspiration pump keeps the air pressure in the low pressure chamber 3 through bleeding point 5; Silica gel circle 4 plays the effect of sealing, and the thickness of silica gel circle 4 is 5 millimeters to 20 millimeters.
Because the low pressure chamber can cause interior plastic cement restrictive coating of plastics extruding cavity and the air pressure between the metal wire rod to be lower than atmospheric pressure; Under the effect of draught head; The plastic cement external sheath layer receives a pressure; Direction is pointed to wire rod cross section symmetrical centre, and the gravitational settling effect of plastic cement external sheath layer becomes not obvious, and the plastic cement external sheath layer is tightr with the combination of metal wire rod in the setting and hardening process.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. metal wire rod sheath extruded mould, it is characterized in that: comprise plastics extruding cavity, low pressure chamber and silica gel circle, the air pressure in low pressure chamber is that 1/10th of external atmosphere pressure arrives one of percentage.
