Preferably, the spiral runner comprises a main runner connected to the injector of the injection molding material feeding channel, a spiral energy reducing runner connected to the main runner, and a branch runner connecting the energy reducing runner and the first drainage channel.
By the arrangement, the liquid outlet speed of the injection molding liquid can be reduced. The injection molding liquid enters the spiral energy-reducing pouring channel through the main pouring channel, the liquid outlet speed of the injection molding liquid is reduced through circuitous movement due to the friction resistance between the pipelines, and then the injection molding liquid enters the first drainage channel through the shunt pouring channel.
As a preferable aspect, the punching unit includes: the stamping device comprises a fixed plate, a stamping cylinder, a guide post, a stamping plate and a guide post, wherein the fixed plate is fixedly arranged on the workbench and at a preset distance, the stamping cylinder is fixedly arranged on the fixed plate, the guide post is fixedly arranged between the workbench and the fixed plate, and the stamping plate is connected with the output end of the stamping cylinder and penetrates through the guide post.
So set up, provide the pressurize pressure. The control unit controls the stamping cylinder to move downwards, so that the stamping plate is driven to move downwards, and the upper die and the lower die are correspondingly pressed. The volume of the injection molding liquid is gradually reduced in the cooling process, the pressure of a melt in the mold begins to drop, the injection molding liquid in the cavity is not compressed enough due to insufficient pressure maintaining pressure, namely the density of the melt is low, and the volume shrinkage end point is lower than the volume of the mold cavity after cooling. The utility model discloses an automatic pressurization forward of stamping system makes the liquid of moulding plastics of back end advance, supplements the shrink of preceding fuse-element to form complete no shrink, the product of deformation.
Preferably, the upper die is fixed on the stamping plate in a detachable installation mode. The detachable installation mode is vacuum chuck or electromagnet adsorption.
So set up, improved the suitability of the device of moulding plastics. In the concrete production process, the producer can change the moulds of different types, models and specifications according to the demand, and the applicability of the injection molding device is improved.
And a plurality of cooling water pipelines are arranged on the lower die and the die strip and spirally wound along the profile of the cavity.
So set up, improve cooling efficiency for production efficiency. The conventional pressing mold generally performs heat dissipation by punching a plurality of heat dissipation holes in the interior of the mold, so that the heat dissipation efficiency is limited. The heat dissipation efficiency of the die can be improved by the aid of the arrangement, and production efficiency of the insulating plug is improved.
Has the advantages that: the utility model relates to a pencil terminal injection mold waters through the spiral energy reduction, reduces the play liquid velocity of flow of the liquid of moulding plastics, prevents to mould plastics liquid when getting into the die cavity, and speed is too high, strikes metal material, forms to splash, dashes the die cavity wall.
