Abstract
The utility model discloses a plastic composite molding mould for pencil, which includes an outer tube body, inlet cores, outlet cores, a connection piece and a discharge hole. The utility model is characterized in that the outer tube body is provided with concentric cylinder shoulder holes on the axial direction; the inlet cores are equipped inside the shoulder holes of the concentric cylinder respectively; the outlet cores are connected with the end part of the inlet cores; the connection piece is connected with one end of the outer tube body; the discharge hole is connected with the other end of the outer tube body. Core material, pole material and fur material can be injected to the utility model through different discharge holes for one-step extrusion forming product. The utility model has advantages of simple technology course, convenient operation and usage, high production efficiency, even heating surface, good thermal stability, hard deformation, easy processing, high assembly precision, and good universality and also can process products in different shapes.
Description
Technical field
The utility model relates to technical field of mold, specifically a kind of plastic pencil composite molding mould.
Background technology
Pencil is a requisite writing implement in the study, penholder all adopts timber to make for a long time, occurred various plastic pencils in recent years in succession, the mould of producing the plastic pencil employing exists many deficiencies: the one, and no lead for retractable pencil guiding, the concentricity of bar material and core material can't guarantee; The 2nd, the angle heart control interval of bar material and cladding is too small, makes the bar cladding that error be arranged, and causes appearance colour inconsistent; The 3rd, bar material feed well is little and shallow, influences inlet amount, and output is restricted.
Summary of the invention
The purpose of this utility model is a kind of plastic pencil composite molding mould that designs at the deficiencies in the prior art, and it has guaranteed the concentricity of bar material and core material, and is easy for operation, and the production efficiency height can be processed difform product.
The concrete technical scheme that realizes the utility model purpose is: plastic pencil composite molding mould, comprise outer cylinder body, import core, outlet core, connector, discharging opening, characteristics are that outer cylinder body axially has the concentric column shoulder hole, the import core is contained in respectively in the concentric column shoulder hole, the outlet core connects import core end, connector connects outer cylinder body one end, and discharging opening connects the outer cylinder body other end; The import core comprises lead for retractable pencil sleeve column, lead for retractable pencil tapered sleeve, bar material tapered sleeve, cladding charging ring, cladding tapered sleeve, and the lead for retractable pencil sleeve column is threaded with the lead for retractable pencil tapered sleeve, and bar material tapered sleeve is sleeved on the lead for retractable pencil tapered sleeve, and cladding charging ring is located between bar material tapered sleeve and the cladding tapered sleeve; Lead for retractable pencil sleeve column center is a hollow shape, and an end outer rim is provided with groove, and the lead for retractable pencil tapered sleeve is a conulite, bar material tapered sleeve endoporus is taper, and cylindrical is cylindricality and taper combination, and cladding charging ring is a cylindrical ring, which is provided with feeding-passage and aperture, cladding tapered sleeve endoporus is taper, and cylindrical is a cylindricality; Outer cylinder body is provided with two charging apertures, and a charging aperture is corresponding with groove, and another charging aperture is corresponding with feeding-passage.
Core material, bar material, cladding are injected the utility model respectively by the different feeds mouth, once squeeze out shaped article, process route is simple and direct, and is easy for operation, the production efficiency height, the utility model heating surface is even, and Heat stability is good is not yielding, handling ease, the assembly precision height, universal performance is good, can process difform product.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
Consult accompanying drawing, the utility model comprises outer cylinder body 1, import core 2, outlet core 3, connector 4, discharging opening 5, import core 2 comprises lead for retractable pencil sleeve column 6, lead for retractable pencil tapered sleeve 7, bar material tapered sleeve 8, cladding charging ring 9, cladding tapered sleeve 10, lead for retractable pencil sleeve column 6 is threaded with lead for retractable pencil tapered sleeve 7, bar material tapered sleeve 8 is sleeved on the lead for retractable pencil tapered sleeve 7, and cladding charging ring 9 is located between bar material tapered sleeve 8 and the cladding tapered sleeve (10); Lead for retractable pencil sleeve column 6 centers are hollow shape, one end outer rim is provided with groove 11, lead for retractable pencil tapered sleeve 7 is a conulite, bar material tapered sleeve 8 endoporus are taper, cylindrical is cylindricality and taper combination, and cladding charging ring 9 is a cylindrical ring, which is provided with feeding-passage 12 and aperture 13, cladding tapered sleeve 10 endoporus are taper, and cylindrical is a cylindricality; Outer cylinder body 1 is provided with charging aperture 14,15, and charging aperture 14 is corresponding with groove 11, and charging aperture 15 is corresponding with feeding-passage 12; Outer cylinder body 1 axially has the concentric column shoulder hole, and import core 2 is contained in respectively in the concentric column shoulder hole, and outlet core 3 connects import core 2 ends, and connector 4 connects outer cylinder body 1 one ends, and discharging opening 5 connects outer cylinder body 1 other end.
The utility model course of work is: lead for retractable pencil material elder generation is by hollow the entering at lead for retractable pencil sleeve column 6 centers, enter the penholder material by the charging aperture on the outer cylinder body 1 14 again, at last enter the foreskin material by the charging aperture on the outer cylinder body 1 15, three kinds of material are in the 3 places composite molding of outlet core, and walk out from discharging opening 5, obtain the plastic pencil of moulding.
The utility model outlet core 3 middle parts can be different geometries, to produce difform product.
