Abstract
The utility model relates to an injection mould of a steel ball holder for guiding elements, mainly composed of a hot running channel device, a mould core, a mould frame, needle moulds and loose core guide disks. The front part of each needle mould used for the wall aperture of moulding work pieces penetrates into each radial through hole of the mould frame, the rear sliding pins of the needle mould are hitched in each tapered slot in circumference arranged on the peripheral loose core guide disk of the mould frame. By rotating the loose core guide disks, the sliding pins of the needle moulds following the guide of the tapered slots to cause the needle moulds to realize propulsion and withdrawing the pattern. The utility model can form steel ball holders with close-packed wall apertures in high quality at one time.
Description
The utility model relates to a kind of injection mold of the guiding ball retainer that rolls.
The retainer of this rolling guiding usefulness is a cylindrical shape, is evenly equipped with multi-turn be used to pack into the through hole of steel ball on the barrel thick and fast, and the line of centres in each file hole has the identical about 7 ° spiral angle of size.At present, this kind retainer is many with aluminium alloy or brass manufacturing, boring again after the turning profile, and cost is high and when taking a lot of work.The purpose of this utility model is to propose a kind of injection mold, is material with engineering plastics (particularly POM), quickly the molded this retainer of one-off pattern.
The purpose of this utility model can reach by following measure: the utility model comprises core rod, framed and hot runner device, it is characterized in that: what also have that needle mould that quantity equates with moulding workpiece wall hole count and quantity equates with the workpiece cinclides number of turns takes out heart positioning disk, there is the sliding pin vertical with the needle mould axial line at the needle mould rear portion, take out circumferentially uniform guiding skewed slot on the heart positioning disk card, respectively taking out heart positioning disk is enclosed within framed periphery stackedly and connects as one with pin, have on framed and the identical radial direction through hole of workpiece cinclides queueing discipline, the needle mould front portion is inserted in the framed radial direction through hole, and the rear portion sliding pin is enclosed in the guiding skewed slot of taking out heart positioning disk.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the cutaway view of the present utility model that is installed on the mould bases.
Fig. 2 is (not comprising the hot runner device) of the present utility model side view cutaway drawing.
Fig. 3 is needle mould figure of the present utility model.
Fig. 4 is the heart positioning disk figure that takes out of the present utility model.
Fig. 5 takes out heart positioning disk A-A cross-sectional schematic for Fig. 4.
Among the figure, (1) ball retainer--workpiece, (2) hot runner device, (3) framed, (4) left support plate, (5) take out heart positioning disk, (6) case, (7) needle mould, (8) right support plate, (9) push rod, (10) push and block plate, (11) guide pillar, (12) moving platen, (13) solid plate, (14) core rod, (15) key, (16) handle.
Cylindrical framed (3) are screwed on solid plate (13), have on framed (3) and the identical radial direction through hole of workpiece (1) cinclides queueing discipline.The needle mould (7) that is used for through hole on molded parts (1) wall is inserted in the through hole of framed (3), needle mould (7) front end has chamfering, be used to be molded on workpiece (1) inwall less than the aperture that will encapsulate steel ball size, there is the sliding pin vertical with the needle mould axial line (7a) at needle mould (7) rear portion, be the power of reducing friction, be with the cover (7b) that rolls on the sliding pin (7a).Framed (3) peripheral, axial stratum is nestable adorning that quantity equates with workpiece (1) the cinclides number of turns take out heart positioning disk (5), smoke on heart positioning disk (5) card circumferentially every circle hole count guide groove, (5a) that equate, that the angle of inclination is identical on the amount of the being evenly equipped with number and workpiece (1) wall.The sliding pin (7a) of needle mould (7) is enclosed in the guide groove (5a), respectively taking out heart positioning disk (5) connects as one with pin, heart positioning disk (5) assembly is taken out in rotation, and guide groove (5a) is just stirred sliding pin (7a), makes each needle mould (7) do to stretch, contract mobile in framed (3) hole simultaneously.Take out heart positioning disk (5) assembly two ends and be connected with left support plate (4), right support plate (8) with screw respectively, ball bearing is respectively enclosed on framed (3) by one in left and right support plate (4), (8), and takes out between heart positioning disk (5) assembly and framed (3) gapped.Case (6) covers on left and right support plate (4), (8) and takes out heart positioning disk (5) assembly periphery and be screwed on support plate.The key (15) that transmits peripheral force connects takes out heart positioning disk (5) assembly and case (6), and handle (16) is arranged on the case (6), pulls handle (16), takes out heart positioning disk (5) assembly and turns over an angle with regard to framed relatively (3).Core rod (14) is fixed on the moving platen (12).On core rod (14) and the bead that moving platen (12) is connected three axially extending bores are arranged, the stripper apparatus of being made up of three push rods (9) and push and block plate (10) is through in these three through holes, for strengthening demoulding guiding, on push and block plate (10), establish a guide pillar (11), correspondingly in core rod (14), be provided with pilot hole.
During use, moving platen (12) advances to the matched moulds position, to M direction turning handle (16), each needle mould (7) front end is conflicted on core rod (14), arrive in the die cavity of forming by core (14), framed (3) and each needle mould (7) by hot runner device injected plastic then.During withdrawing pattern, to N direction turning handle (16), the guide groove (5a) of taking out heart positioning disk (5) guides the sliding pin (7a) at each needle mould (7) rear portion to move, and the needle mould footpath is outwards moved, until extracting from the workpiece (1) of moulding.During die sinking, moving platen (12) is drawn back, and workpiece (1) withdraws from framed (3) with moving platen (12) upper mold core (14), uses object blocks push and block plates (10) in the process that retreats, push rod (9) just ejects workpiece (1) from core rod (14), moving platen (12) puts in place subsequently and stops.
The utility model novel structure, the parts flexible movements, a plurality of needle moulds advance and the demoulding exactly simultaneously, guarantee that the workpiece one-off pattern is molded, have improved work efficiency greatly and have saved a large amount of noble metals.
