Abstract
The utility model provides a core-pulling auxiliary mechanism inside a die-casting part, which comprises a movable die, a push rod fixed plate with an inner cavity, a push rod base, a hollow connecting rod and a forming push rod, wherein the push rod fixed plate with the inner cavity is movably connected with the movable die in the vertical direction; the push rod base is horizontally arranged in the inner cavity of the push rod fixed plate; the hollow connecting rod is fixed on the push rod base; the forming push rod can longitudinally slide inside the connecting rod; a pulley is mounted on the push rod base; and a gap for activities is preserved between the horizontal direction of the pulley and the inner cavity of the push rod fixed plate, so that the forming push rod can laterally slide when being ejected. The utility model improves the quality and the work efficiency of the die-casting part.
Description
Technical field
The utility model relates to a kind of die casting servicing unit, relates in particular to a kind of die casting inside auxiliary body of loosing core.
Background technology
As shown in Figure 4, usually during design of Die Casting, there is jog inside, die casting 7 side, generally need to adopt loose plug 5 ', before matched moulds loose plug 5 ' is put into mould, loose plug 5 ' ejects together with die casting 7 after the die casting, by hand loose plug 5 ' is separated with die casting 7 then, enter next circulation then, the loose plug of this routine makes die casting damage when separating easily, produce plucking and operating efficiency is low.Also do not occur in the market a kind of be beneficial to loose plug from die casting break away from from auxiliary body.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of
For achieving the above object, the utility model provides a kind of die casting inside auxiliary body of loosing core, and comprises dynamic model, and its key is: also comprise the ejector pin retaining plate of a band inner chamber, this ejector pin retaining plate connects with described dynamic model in the vertical direction activity; One horizontally disposed push rod base among described ejector pin retaining plate inner chamber; Be fixed on the described push rod base the hollow connecting rod and can be at the forming ejector pin of the inner longitudinal sliding motion of described connecting rod; Reservation activity space between the inner chamber of pulley and its horizontal direction and described ejector pin retaining plate is installed on the described push rod base, can laterally slides when described forming ejector pin is ejected.
Laterally slide when ejecting for the ease of forming ejector pin, therefore the angle between described forming ejector pin and the described push rod base is α, 75 °＜α＜90 °.
Further, described α=83 °.
Friction when laterally sliding when ejecting in order to reduce forming ejector pin, therefore described push rod base is installed four pulleys and is become rectangular arrangement, and two pulley rooms all connect by circular shaft longitudinally.
Further, described ejector pin retaining plate is arranged on the bottom of described dynamic model.
Further, described forming ejector pin head is provided with loose plug, and this loose plug is slidingly arranged in die casting inside.
Technique effect of the present utility model is: owing between forming ejector pin and the described push rod base angle is arranged is α, 75 °＜α＜90 °, reservation activity space between the inner chamber of pulley and its horizontal direction and ejector pin retaining plate is installed on the push rod base, when the moulding push rod is released obliquely upward, forming ejector pin slides and the foundry goods disengaging to horizontal direction, has improved the quality and the operating efficiency of die casting.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.

The specific embodiment
Embodiment 1
As Fig. 1, Fig. 2, shown in Figure 4, a kind of die casting inside auxiliary body of loosing core comprises dynamic model 1, and the ejector pin retaining plate 2 of a band inner chamber is set in the bottom of dynamic model 1, and this ejector pin retaining plate 2 connects with the activity of dynamic model 1 in the vertical direction, can slide up and down; Horizontally disposed among ejector pin retaining plate 2 inner chambers have a push rod base 3, and push rod base 3 is installed four pulleys 6 and become rectangular arrangement, and vertically two pulley rooms arranging all connect by circular shaft.A hollow connecting rod 4 and can be at the forming ejector pin 5 of connecting rod 4 inner longitudinal sliding motions is set on push rod base 3; Reservation activity space between the inner chamber of pulley 6 and its horizontal direction and ejector pin retaining plate 2 is installed on the push rod base 3, can laterally slides when forming ejector pin 5 is ejected.Described forming ejector pin 5 heads are provided with loose plug 5 ', and this loose plug 5 ' is slidingly arranged in die casting 7 inside.Angle between forming ejector pin 5 and the push rod base 3 is α=83 °.
Operation principle of the present utility model is:
As shown in Figure 1 and Figure 2, this moment, mould was in the matched moulds state, and push rod base 3 is in the left side of ejector pin retaining plate 2 inner chambers, after die casting 7 is compression molded into type, mould remaining time end, and die sinking; Then, as shown in Figure 3, forming ejector pin 5 ejects ejector pin retaining plate 2, pulley 6 rises with ejector pin retaining plate 2, die casting 7 is ejected, because the angle α of an inclination is arranged between forming ejector pin 5 and the push rod base 3, so the pulley on the push rod base 36 slides to the right in the inner chamber of ejector pin retaining plate 2, loose plug 5 ' on the forming ejector pin 5 progressively shifts out at this moment, at this moment can freely take out die casting.
Angle between forming ejector pin 5 and the push rod base 3 is α=76 °.Other technical characterictic is with embodiment 1.
Angle between forming ejector pin 5 and the push rod base 3 is α=89 °.Other technical characterictic is with embodiment 1.
