Description
Technical field
The utility model relates to the Coinjection molding apparatus field, especially a kind of long clavate composite insulator Coinjection molding apparatus.
Background technology
The composite insulator injection moulding method is that plug is placed in the middle of the upper and lower umbrella cover mould, the silicon rubber outer insulating material is filled with the umbrella cover mold cavity at a high speed by injector, then through the baking moulding.Spray sizing material from injection product umbrella cover mold injects mouth, the sizing material thrust of a plurality of injection ports makes plug produce the S shape and forms the sheath thickness and differ, the synthetic insulator of special 220kV and above electric pressure is because length is long, plug adopts monolateral fixing, after the compression molding of injection silicon rubber outer insulating material, its jacket thickness changes greatly, and non-uniform phenomenon is serious.The composite insulator sheath is used for protecting plug, and operational reliability, the life-span of it and product are closely related.Many producers reach relevant criterion for making the product jacket thickness, make it still can reach standard at the minimum thickness of uneven situation lower jacket even integral body has strengthened the thickness of sheath, so not only increase the own wt of composite insulator, also increase cost.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, safe and reliable, composite insulator Coinjection molding apparatus that production efficiency is high is provided, and composite insulator thickness of insulating layer that this device is produced is even.
For this reason, the composite insulator Coinjection molding apparatus that the utility model provides, comprise injector and die device, described die device, comprise the upper and lower bearing support that can fasten mutually, be arranged at the upper and lower umbrella cover mould that on the upper and lower bearing support, also can be buckled into airtight die cavity mutually respectively, and the injection pipeline of a plurality of connection injector and die cavity, it is characterized in that: described subumbrella mold two ends are provided with the gold utensil governor motion, and described lower supporting frame is provided with a plurality of plug detent mechanisms of arranging along subumbrella mold length direction.
Be respectively arranged with on the described upper and lower bearing support that two transverse horizontal are extended, and symmetrical subumbrella mold.
Described plug detent mechanism comprises first locating bar, longitudinally is fixedly arranged on subumbrella mold one side horizontal-extending, and the one end stretches in the mould and withstands plug; Second locating bar longitudinally is movably set in subumbrella mold opposite side horizontal-extending, and the one end can stretch in the mould and withstand plug; Driving mechanism is used to drive second locating bar and is withstanding plug and leaving between the plug and move.
Described first locating bar is arranged between the two subumbrella molds.
The end that described first, second locating bar contacts with plug has the circular arc contact-making surface suitable with the plug profile respectively.
Described first, second locating bar is crisscross arranged in subumbrella mold both sides or is symmetricly set in subumbrella mold both sides.
Described gold utensil governor motion, the screw that comprises the framework that is fixedly set on the lower supporting frame, is formed on the framework and connects with transverse horizontal, be actively set in the bolt in the screw, described bolt is provided with guide vane end stop near an end of gold utensil, and described guide vane end stop withstands gold utensil.
The utlity model has following beneficial effect:
Adopt two groups of die cavitys can once produce two composite insulators, when ensuring the quality of products, improved production efficiency greatly; The relative position of location gold utensil in die cavity can be regulated and limit to location gold utensil governor motion flexibly, prevents that the insulating barrier injection around the plug is inhomogeneous; The plug detent mechanism can guarantee that plug can not cause thickness of insulating layer inhomogeneous because of sizing material thrust is offset when injection.
Description of drawings
