Abstract
The invention discloses an angle ejector rod with a stress step. According to the technical scheme, the angle ejector rod with the stress step comprises an angle ejector rod body (1) and the stress step (11), wherein the stress step is arranged on a cylindrical surface of the angle ejector rod body and is positioned below a joint of the angle ejector rod body and an angle ejector block; a step groove for bearing the stress step is formed in the bottom of an accommodating groove of a moving mold core; and during working, interference tension and impact force which are generated by resetting inertia of an ejector plate are born by the stress step, so that a key pin rabbet and a key pin which are used for connecting the angle ejector rod body and the angle ejector block are protected against being damaged. The shortcomings of high maintenance cost, low production efficiency and low yield of products in the prior art are overcome. The force damaging the key pin rabbet and the key pin which are used for connecting the angle ejector rod body and the angle ejector block is born by the stress step, so that the aims of reducing maintenance cost, increasing production efficiency and increasing the yield of the products are achieved during production and running of an injection mold.
Description
Technical field
The present invention relates to the angle ejector rod parts of injection mold, specifically refer to for injection mold and support a kind of angle ejector rod that is provided with stressed step that slanted kicking block carries out the slant-top core-pulling demoulding.
Background technology
Angle ejector rod is to support for injection mold the parts that slanted kicking block carries out the slant-top core-pulling demoulding, the angle ejector rod of prior art is cylindrical shaft-like steel components, during application, consult Fig. 3, the upper end of angle ejector rod is connected with the slanted kicking block that is provided with moulded products profile by key pin, slanted kicking block slides and is embedded in the resettlement groove of dynamic mould core, the lower end of angle ejector rod is connected with the shoes of shoes pair, the slide of shoes pair is fixedly connected on top board, during work, drawing back during ejecting and resetting when top board drives angle ejector rod and drives slanted kicking block tiltedly to loose core along resettlement groove moved;
Injection mold is in actual motion, the interference pulling force that the inertia resetting due to top board can pull slanted kicking block retraction resettlement groove to produce at angle ejector rod, simultaneously, impulsive force that can generation is collided when the bottom of slanted kicking block and the bottom land of resettlement groove contacts, above-mentioned interference pulling force all collects in impulsive force the key pin place that is connected angle ejector rod and slanted kicking block, for a long time it, connecting the key pin tenon mouth of angle ejector rod and slanted kicking block and key pin fractures and slanted kicking block disengaging accident because of damaged generation angle ejector rod, need when the time comes to shut down dismounting die change angle ejector rod, cause mould maintenance cost to increase, injection moulding production efficiency declines, goods fraction defective increases, therefore, prior art exists maintenance cost high, production efficiency is low, the problems and shortcomings that job efficiency is low.
Summary of the invention
The problems and shortcomings that exist for above-mentioned prior art, the present invention adopts on the cylinder that is positioned at the angle ejector rod below angle ejector rod and slanted kicking block connecting portion and is provided with a stressed step, the step groove of a stressed step of carrying is set at the bottom land of the resettlement groove of dynamic mould core, during work, interference pulling force and impulsive force that the inertia that top board resets produces are born by stressed step, make the key pin tenon mouth and the key pin that connect angle ejector rod and slanted kicking block exempt from injured technical scheme, a kind of angle ejector rod that is provided with stressed step is provided, be intended to by infringement angle ejector rod and the key pin tenon mouth of slanted kicking block and the power of key pin are turned by stressed step and born, make the production run of injection mold reach reduction maintenance cost, enhance productivity, improve the object of job efficiency.
The object of the present invention is achieved like this: a kind of angle ejector rod that is provided with stressed step, comprise angle ejector rod and stressed step, centered by described angle ejector rod, be provided with the steel components of the cylinder step tubulose of hollow cooling water channel, the top cylinder of angle ejector rod is provided with the columniform flange step of a circle and is called stressed step;
Application connects, and in the bottom outlet of the upper end insertion slanted kicking block of angle ejector rod, by being located at the key pin tenon mouth of angle ejector rod and slanted kicking block, with key pin, is fixed to one another connection, and now, described weighted table component level is in the below of the bottom surface of slanted kicking block; The step groove of a described stressed step of carrying is set at the bottom land of the resettlement groove that is positioned at dynamic mould core of settling described slanted kicking block for sliding, and the bottom land of step groove contacts with below described stressed step; The lower end of angle ejector rod slides through the oblique top guide hole that is positioned at dynamic mould core and dynamic model support plate, and the lower end of angle ejector rod is connected with the shoes that is positioned at the shoes pair on top board, and the slide of shoes pair is fixedly connected on top board.
Operation principle and beneficial effect
During work, drawing back during ejecting and resetting when top board drives angle ejector rod and drives slanted kicking block tiltedly to loose core along resettlement groove moved; The interference pulling force that the reset inertia of top board produces and impulsive force are born by the bottom land of stressed step and described step groove, make the key pin tenon mouth and the key pin that connect angle ejector rod and slanted kicking block exempt from stressed infringement.
This member is because the bottom land that infringement angle ejector rod and the key pin tenon mouth of slanted kicking block and the power of key pin are turned by stressed step and described step groove bears, the service life of angle ejector rod and slanted kicking block is extended, make the production run of injection mold reduce maintenance cost, improved production efficiency, improved job efficiency; In addition, this member, because the standard gauge that is easy to simple in structure is formatted, therefore has pervasive general dissemination.
Above-mentioned, the present invention adopts on the cylinder that is positioned at the angle ejector rod below angle ejector rod and slanted kicking block connecting portion and is provided with a stressed step, the step groove of a stressed step of carrying is set at the bottom land of the resettlement groove of dynamic mould core, during work, interference pulling force and impulsive force that the inertia that top board resets produces are born by stressed step, make the key pin tenon mouth and the key pin that connect angle ejector rod and slanted kicking block exempt from injured technical scheme, having overcome prior art exists maintenance cost high, production efficiency is low, the problems and shortcomings that job efficiency is low, a kind of angle ejector rod that is provided with stressed step providing, by infringement angle ejector rod and the key pin tenon mouth of slanted kicking block and the power of key pin are turned by stressed step and are born, make the production run of injection mold reach reduction maintenance cost, enhance productivity, improve the object of job efficiency.
