Abstract

A kind of identical reversion detent mould structure of the concave-convex type that plastic part silk tooth can be allowed to be accurately positioned, reversion detent and two systems structure of trackslipping are added in drive mechanism, the indefinite of its direction position is playbacked after they make a tooth rotation exit plastic part, the lowest order that its detent bar for inverting catch system touches detent wheel will be blocked to the interface of highest order and be positioned, system of trackslipping is by the resistance from detent wheel, sprocket wheel coenosarc of coincideing can be given to one thrust of spring, by compression, the identical wheel inclined-plane mutually identical with identical sprocket wheel coenosarc just skids spring, so that motor dallies.

Description

Concave-convex type, which coincide, inverts detent mold

This division original application title inverts detent mold, application number 2019100284114, applying date 2019.01.11 day.

Technical field

The present invention relates to a kind of mould structures, and the concave-convex type that can especially position to the silk tooth of plastic part, which coincide, inverts detent Mold.

Background technique

Currently, the localization method of well known plastic part silk tooth, be that mold is preceding altogether places silk tooth by hand, after die sinking again It produces and from plastic part, inconvenient and inefficiency.

Summary of the invention

The defect of craft modes of emplacement used by positioning in order to overcome prior art plastic part silk tooth, the present invention provide A kind of identical reversion detent mould structure of new concave-convex type, it can be accurately positioned to the silk tooth of plastic part.

The technical solution adopted by the present invention to solve the technical problems is: the mold releasability of existing band silk tooth product, silk tooth Its direction position is indefinite after plastic part is exited in rotation, and it is exactly the silk that direction position is indefinite that concave-convex type, which coincide, which inverts detent mold, Tooth is restored to the direction position of setting.That is, not needing fixed-direction position in plastic part silk tooth and driving the mould of demoulding by motor In lamps structure, first, adding a detent wheel (14) on silk tooth (8) or transmission shaft (10) in the drive mechanism of mould inside And matched detent spring (15), washer (16), detent bar (17), adapter lug (18), detent wheel is using spiral, and half Gradually to big, least radius and crossing for maximum radius are a protrusion interfaces to diameter by small, when mold releasability acts, detent bar Along the contact surface of detent wheel from low level gradually to after a high position, then it can fall with the rotation of detent wheel and the effect of detent spring Low level rises and falls sliding, and when reversion, the lowest order that detent bar touches detent wheel will be blocked to the interface of highest order, at this moment, silk The direction position of tooth will meet the design requirement of plastic part silk tooth direction position, when detent wheel is mounted on transmission shaft, gear one (19) and the size of gear two (20) with the number of teeth wants identical, consistent with the revolving speed of axis where ensureing two, so that mold work makes Direction position in detent and the requirement of silk tooth after installation and debugging will not change；Second, being fixed on motor drive shaft (34) originally On sprocket wheel repack the identical sprocket wheel coenosarc (37) that can be trackslipped and matched identical wheel (36), positioning pin (30), flat into Spherical bearing (32), spring (38), clamp nut (39), screw rod (40), spring capping (41), nut (42), coincide wheel and kiss Closing the identical of sprocket wheel coenosarc can be male-type or concave-convex type, and attached drawing show male-type, and concave-convex type is by one of protrusion Remove and go to opposite direction carving the hole of a moulding identical as the protrusion retained, should be no less than by coincideing by two pairs, three pairs or more Can it is more steady, motor (33) rotate demould when, coincide wheel and identical sprocket wheel coenosarc be vertical face mutually coincide put forth effort, no It can skid, detent bar gradually arrives the high-order sliding that rises and falls along the low level of detent wheel tread, and in motor reversion, coincide wheel and kiss Conjunction sprocket wheel coenosarc, which is that inclined-plane is mutually identical, puts forth effort, and at this moment, detent wheel also inverts, and detent bar touches the lowest order of detent wheel to most It being blocked when the interface of a high position, detent wheel can not rotate, this has just given from the very big resistance in one, upstream motor driven direction, As soon as the inclined-plane that spring is mutually coincide by compression skids, so that motor is empty so that sprocket wheel coenosarc of coincideing is given to spring thrust Turn, mold is got and accorded with one by one in each molding, injection molding, pressure maintaining, die sinking, rotation demoulding, the reciprocating action of reversion detent Close desired product.

The beneficial effects of the present invention are: mechanical automation degree is high, high-efficient, at low cost, high efficiency.

Specific embodiment

Part of the upper die: feed inlet (3) and 4 guide posts (2) are put into upper mold cover board (4) respectively and cavity template (6) is right In the hole answered, and four cover board screws (1) are tightened, there are appropriately sized injecting hole in feed inlet and cavity (5).

Part of the lower die: putting into lower die upper plate (12) for bearing one (9) and bearing two (11) respectively, transmission shaft and silk tooth difference It puts into bearing one and bearing two, for detent wheel on transmission shaft, bearing three (21), gear one and gear two put into lower die lower plate (13), altogether lower die upper plate and lower die lower plate, so that silk tooth and transmission shaft put into gear two and bearing three and gear respectively It in one, then by type body (7) threading silk tooth and lower die lower plate, tightens screw (25), bearing four (26) is under transmission shaft and lower die On plate, detent wheel, gear one and gear two and the axis at place have non-circular structure to cooperate or fix anti-skidding dislocation measure, card Position spring, washer, detent bar and adapter lug are put into lower die upper plate, and rotating drive shaft determines silk tooth to detent bar detent position Direction position and the requirement of product recorded silk tooth if do not met and needed the angle that adjusts, dismantled lower die upper plate and lower die Lower plate adjusts the identical point of gear two and gear one, the angle that the angle that gear two adjusts needs to adjust with the silk tooth just recorded Degree is consistent, then assembles recovery, then stop bit circle (27) and sprocket wheel (28) are mounted on transmission shaft, under four guide sleeves (22) are put into In mould upper plate and lower die lower plate, then with 4 or 6 lower die screws (24) support block (23) on mold both sides and support block pad (29) are tightened It is fixed on lower die upper plate.

Motor portion: the wheel dress that coincide is fixed on the motor and with positioning pin, and screw rod is screwed into motor drive shaft and with compression spiral shell Mother is fixed, then identical sprocket wheel coenosarc, plane bearing, spring, spring capping and nut are assembled.

The guide post of upper mold injects the guide sleeve of lower die, then motor is fixed in lower die with bracket (35), is placed in mold It is installed on the upward one side of injection molding machine, is installed chain (31), installation connects water circulation cooling system.
