Pass through technique scheme; The mould of plastics with slide block core-pulling mechanism that the utility model provides is provided with secondary slide block, during die sinking on master slider; Oil cylinder drives the master slider motion; Master slider drives secondary slide block and moves together, because the chute on the master slider is obliquely installed, master slider also can drive secondary slide block and on its vertical direction, move.Master slider is twitched certain distance, and major and minor slide block can break away from product fully, and completion is loosed core.At this moment, under the effect of injection machine push rod ejecting force, the push pedal drive is made bar running channel is ejected die cavity together with product, and under the gravity effect, the product collaborative running channel drops along the axis direction of core voluntarily immediately, accomplishes product stripping smoothly.Therefore, realized the purpose of improving the quality of products, enhancing productivity having reduced production cost effectively through the utility model.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the disclosed a kind of structural representation with mould of plastics of slide block core-pulling mechanism of the utility model embodiment;
Fig. 2-5 is the disclosed a kind of opening and closing mode structure sketch map with mould of plastics of slide block core-pulling mechanism of the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
The utility model provides a kind of mould of plastics (with reference to Fig. 1) with slide block core-pulling mechanism, comprises running gate system 101, cover half, dynamic model, die and the slide block core-pulling mechanism between dynamic model and cover half.Cover half comprises solid plate 104 and cover half benevolence 103, and dynamic model comprises moving platen 106, mavable module core 105, push pedal 107 and make bar 109 that die comprises core and die cavity (not indicating among the figure), cover half benevolence 103 and mavable module core 105 common die cavity that forms when matched moulds.
The slide block core-pulling mechanism comprises master slider 114, secondary slide block 115, take-up housing 112 and oil cylinder 113; Take-up housing 112 is fixed on the moving platen 106; Be slidingly connected between master slider 114 and the take-up housing 112; Oil cylinder 113 is positioned at outside the mould and with master slider 114 and is connected, and is slidingly connected between master slider 114 and the secondary slide block 115.An end of corresponding secondary slide block 115 is provided with inclined-plane one and the T type chute parallel with inclined-plane one on the master slider 114, and an end of secondary slide block 115 corresponding master sliders 114 is provided with inclined-plane two and the T type hanging platform parallel with inclined-plane two, and inclined-plane one and inclined-plane two parallel.The hanging platform of T type is fastened on when sliding in the chute of T type, and secondary slide block 115 can not break away from master slider 114.The hanging platform of dove-tail form engages also with chute each other can realize identical function.Take-up housing 112 is provided with T type slide rail, and master slider 114 is provided with T type boss, and the boss of T type is fastened on when sliding in the slide rail of T type, and master slider 114 can not break away from take-up housing 112.The boss of dove-tail form engages also with slide rail each other can realize identical function.
Wherein, an end of master slider 114 corresponding take-up housings 112 is provided with stopper slot, and take-up housing 112 is provided with gag lever post 111.One end of gag lever post 111 is arranged in stopper slot, the twitch distance of restriction master slider 114, also limits the distance that it resets.
The process that the utility model is accomplished a formed product is:
As shown in Figure 2, mould closes, molten plastic gets into from running gate system 101, flows in the mold cavity, and product 102 moulding are accomplished.
Shown in Fig. 3-4, when die sinking, dynamic model is to left movement; Oil cylinder 113 drives master slider 114 motions; Master slider 114 drives secondary slide block 115 and moves together, because the chute on the master slider 114 is obliquely installed, master slider 114 also can drive secondary slide block 115 and on its vertical direction, move.When master slider 114 is twitched certain distance, major and minor slide block 114,115 can break away from product 102 fully, accomplishes side core-pulling.
As shown in Figure 5, when major and minor slide block 114,115 broke away from product fully, the push rod of injection machine moved right, and passes the circular hole on the supporting plate 108, dragged push pedal 107 and moved right, and push pedal 107 meeting drives are made bar 109 and moved right together.Make bar 109 running channel is ejected die cavity together with product 102, under the gravity effect, product 102 collaborative running channels drop along the axis direction of core voluntarily, accomplish product 102 demouldings smoothly immediately.
After a product 102 machined, oil cylinder 113 promoted major and minor slide block 114,115 and gets back in the die cavity.Then, the mould matched moulds, injection machine push rod retraction, push rod 109 bounces back under the active force of spring 110.
Under the condition that the intensity of the shape of product and master slider 114 allows, secondary slide block 115 can be a plurality of.
The mould of plastics that the utility model provides with slide block core-pulling mechanism; On master slider 114, be provided with secondary slide block 115; During die sinking, oil cylinder 113 drives master slider 114 motions, and master slider 114 drives secondary slide block 115 and moves together; Because the chute on the master slider 114 is obliquely installed, master slider 114 also can drive secondary slide block 115 and on its vertical direction, move.Therefore, realized the purpose of improving the quality of products, enhancing productivity having reduced production cost effectively through the utility model.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
