Description
Technical field
The present invention relates to a kind of double-component injection front-template rotary-table device, this device is applicable on two component injection-moulding plastic equipment, but the goods of two kinds of different materials of production requirement or color, and the goods dead head of producing gained is not at the smooth surface of goods.
Background technology
Generally, when the plastic products (as bottle for cosmetics, bottle cap etc.) of double-component injection container for moulding shape, the male model of mould is installed on the moving die plate, and master mold is installed on the front template.Injection is made up of major and minor injection double injection, after the injection moulding for the first time, rotate mould by the male model on the moving die plate, injection is for the second time finished in the back, location, after so the goods injection is finished, generally at container outside (the bottle end or bottle cap section), this is a bigger defective to products appearance to dead head.If in order to consider to avoid above defective and designing mould, this is a very loaded down with trivial details engineering and spends huge.
Chinese patent 200920117750.1 " the clear double-colored rotating-table apparatus of injector " discloses a kind of rotating-table apparatus that is used for injector, this rotating-table apparatus is arranged on the moving die plate, male model is loaded on the moving die plate, when producing container-like plastic products, container is attached on the male model, so the dead head of goods influence the surface quality of goods and the aesthetics of outward appearance at the outer surface of goods, and owing to may improve the scrappage of goods during the pruning dead head.This device can rotate smoothly in order to make rotating disk, ejects the rotating disk gap that rotates thereby be provided with spring, be that spring is finished because the gap produces, so the gap length that produces is not exclusively, and instability during dial rotation.When die sinking, mould opening force can have active force to parts such as rotating disks in addition, produces damage, influences service life.
Disclose a kind of die fixture in the Chinese patent 200910101626.0 " double coloured plastic injection machine ", its spinning movement is the center rotation around die fixture, and action realizes complicated, makes difficulty, the manufacturing cost height.
Adopt above-mentioned two produced goods of patent equipment all not overcome the problem that dead head exposes, dead head influences surface quality and outward appearance at the outer surface of goods, and may cause scrapping of goods when pruning dead head.Male model is loaded on the moving die plate, and container is attached on the male model, and master mold is loaded on the front template, and the plastics of goods flow into moulding on the die joint of male model master mold from the runner of master mold.So when producing container-like plastic products, so the dead head of goods is at the outer surface of goods.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency in the prior art and a kind of cheap, simple in structure, the double-component injection front-template rotary-table device that can make perfect outward appearance plastic products is provided.When the present invention satisfied common double component injection product requirements, the dead head that has solved goods was exposed to exterior defects.
The technical scheme that the present invention solves the problems of the technologies described above employing is: this double-component injection front-template rotary-table device, it is characterized in that: comprise rotating disk, rotating shaft and front template, described rotating disk is respectively arranged with positioning sleeve up and down, be respectively arranged with alignment pin in each positioning sleeve, each alignment pin is connected with a positional cylinder, the rotating disk home position is fixedlyed connected with rotating shaft one end, rotating shaft is rotated and is arranged on the front template, bearing and thrust bearing are housed between rotating shaft and the front template, front template is provided with servo motor, servo motor drives rotating disk by the engagement of pinion and rotating disk, be provided with a plurality of steel balls between rotating disk and the front template, be respectively arranged with corresponding injection orifice on described rotating disk and the front template, each one of injection orifice the right and left, each injection orifice next door is respectively arranged with a cover transposition control device.Master mold is loaded on the moving die plate, and male model is loaded on the front template, and container is attached on the male model, and the plastics of goods flow into moulding on the die joint of male model master mold from the runner of male model.So when producing container-like plastic products, so the dead head of goods is at the inner surface of goods.Equally, in male model rotation back injection, the dead head of goods is equally at the inner surface of goods.Bearing and thrust bearing are housed between rotating shaft and the front template, when freely rotating, can bear certain radial load so that can make rotating shaft, thrust bearing can be eliminated mould opening force to part active forces such as rotating disks when die sinking, avoid correlated parts to be subjected to unnecessary damage.Be provided with a plurality of steel balls between rotating disk and the front template, when dial rotation, because the rolling action of steel ball, can make rotating disk play rolling effect, can not make between rotating disk and the front template and produce dry friction, the depth of parallelism requirement on the big plane of the mould installed surface of rotating disk and front template can be guaranteed simultaneously, the matched moulds effect of mould can be guaranteed.
