Abstract
The utility model discloses a special mold for forming of an injection molding pipeline. The special mold adopts a module type structure, and is convenient to mount and dismount, good in material passability and high in finished product quality. The special mold comprises an internal mold fixing sleeve and an external mold fixing sleeve, which are arranged on a rotating shaft of an injection molding machine; an external mold is fixedly arranged on the external mold fixing sleeve through external mold fastening screws; a middle mold is fixedly arranged on the internal mold fixing sleeve through middle mold fastening screws; an internal mold is fixedly arranged on the outer side of the middle mold through internal mold fastening screws; the internal mold, the middle mold and the outer edge of the internal mold fixing sleeve are mutually matched; the external mold fixing sleeve is matched with the inner edge of the external mold; the internal mold, the middle mold and the outer edge of the internal mold fixing sleeve form a pipe passage with the external mold fixing sleeve and the inner edge of the external mold; an external mold calibrating ring made of polytetrafluoroethylene material is arranged on the inner wall of the inlet of the external mold; and an internal mold calibrating ring made of polytetrafluoroethylene material and matched with the external mold calibrating ring is arranged on the outer wall of the inlet of the internal mold.
Description
Technical field
The utility model relates to pipe production equipment, is specifically related to a kind of pipeline injection moulding production equipment.
Background technology
Along with the development of material technology, municipal administration is used HDPE, PVC, plastic material production in a large number with pipeline.This kind of pipeline generally adopts Shooting Technique production, first materials in the tube are heated, then by extruder by materials in the tube through the mould extrusion molding.Existing injection moulding pipeline mould generally adopts the monoblock cast mode to produce, and dismounting, installation are all comparatively complicated; Simultaneously, though the materials in the tube passage of existing mold through PROCESS FOR TREATMENT such as polishings, surface roughness is still larger, material flow frictional force when the materials in the tube passage is larger, the pipeline finished surface is of low quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of injection moulding pipeline moulding particular manufacturing craft, and it adopts modular organization, installation, convenient disassembly, and the material trafficability characteristic is good, and end product quality is high.
For addressing the above problem, injection moulding pipeline moulding particular manufacturing craft of the present utility model, comprise the internal mold fixed cover and the external mold fixed cover that are arranged in the injection machine rotating shaft, be fixedly installed external mold by the external mold hold-down screw on the external mold fixed cover, be fixedly installed middle mould by middle mould hold-down screw on the internal mold fixed cover, the middle mould outside is fixedly installed internal mold by the internal mold hold-down screw; The outer rim of described internal mold, middle mould, internal mold fixed cover matches, and the inner edge of described external mold fixed cover, external mold matches, and forms the materials in the tube passage between the outer rim of internal mold, middle mould, internal mold fixed cover and external mold fixed cover, external mold inner edge; The inwall of external mold porch is provided with the external mold sizing ring of polytetrafluoroethylene (PTFE) material, and the outer wall of internal mold porch is provided with the internal mold sizing ring of the polytetrafluoroethylene (PTFE) material of mating with external mold sizing ring.
After having adopted technique scheme, internal mold of the present utility model, middle mould, external mold adopt modular organization, installation, convenient disassembly.The inwall of external mold porch is provided with the external mold sizing ring of polytetrafluoroethylene (PTFE) material, the outer wall of internal mold porch is provided with the internal mold sizing ring of the polytetrafluoroethylene (PTFE) material of mating with external mold sizing ring, the polytetrafluoroethylene (PTFE) material possesses good self-lubricating property, when material enters, skin-friction force significantly descends, flow velocity is uniform and stable, and trafficability characteristic is good, and production efficiency is high, finished product outer surface fineness is good, and product quality obviously improves.
The accompanying drawing explanation
Fig. 1 is the structural representation of injection moulding pipeline moulding particular manufacturing craft of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, injection moulding pipeline moulding particular manufacturing craft of the present utility model, comprise the internal mold fixed cover 1 and the external mold fixed cover 2 that are arranged in the injection machine rotating shaft, be fixedly installed external mold 4 by external mold hold-down screw 3 on external mold fixed cover 2, be fixedly installed middle mould 10 by middle mould hold-down screw 9 on internal mold fixed cover 1, middle mould 10 outsides are fixedly installed internal mold 5 by internal mold hold-down screw 8.
The outer rim of described internal mold 5, middle mould 10, internal mold fixed cover 1 matches, and its joint polishing, be convenient to material and pass through.The inner edge of described external mold fixed cover 2, external mold 4 matches.Along the injection machine rotating shaft radially, external mold fixed cover 2, external mold 4 are arranged on outer ring, and internal mold 5, middle mould 10, internal mold fixed cover 1 are arranged on inner ring; Form materials in the tube passage 11 between the outer rim of internal mold 5, middle mould 10, internal mold fixed cover 1 and external mold fixed cover 2, external mold 4 inner edges; This materials in the tube passage 11 and injection machine rotating shaft coupling along circumference.
The inwall of external mold 4 porch is provided with the external mold sizing ring 6 of polytetrafluoroethylene (PTFE) material, and the outer wall of internal mold 5 porch is provided with the internal mold sizing ring 7 of the polytetrafluoroethylene (PTFE) material of mating with external mold sizing ring 6.External mold sizing ring 6 matches each other with internal mold sizing ring 7, and be arranged on the porch of mould, the materials in the tube of heating coordinate the pipeline formed to enter mould with internal mold sizing ring 7 through external mold sizing ring 6, because the polytetrafluoroethylene (PTFE) material possesses self-lubricating function, thereby mobile materials in the tube surface obtains thick step processing, roughness obviously descends, and by functional, effectively improves the quality of products.
Axial along the injection machine rotating shaft, external mold sizing ring 6 is identical with the length of internal mold sizing ring 7.Materials in the tube passage 11 is divided into intake section 110, amplifier section 112, horizontal component 113.External mold sizing ring 6 is that 1:1.5～2 are comparatively suitable with the Length Ratio of the intake section 110 of materials in the tube passage 11.
