Abstract
The utility model discloses an external limiting ejection mechanism, which comprises an upper press rod (2), an upper limiting rod sleeve (5), a lower limiting rod (6) and an upper limiting rod (3). One end of the upper press rod (2) is fixedly connected to an upper ejection plate (1), the upper limiting rod sleeve (5) is fixedly connected to an upper core box fixing plate (4), the lower limiting rod (6) and the upper limiting rod (3) are fixedly connected to a lower core box fixing plate (4), the upper press rod (2) is placed right above the upper limiting rod (3), the upper limiting rod (3) is movably sleeved into an inner cavity of the upper limiting rod sleeve (5), a radial bump (3.1) is disposed at the upper end of the upper limiting rod (3), and a limiting groove (5.1) which matches with the radial bump (3.1) is arranged on the upper portion of the inner cavity of the upper limiting rod sleeve (5). In a total core ejection process, lots of material cost is saved particularly for core box dies with higher requirements to materials of core box bodies, production cost is lowered, and simultaneously, market competitiveness of the dies is also improved.
Description
Technical field
The utility model relates to sand casting core box mould applications, the spacing ejecting mechanism of particularly a kind of external.
Background technology
The in process of production core shooters that adopt horizontal parting of casting core box mould, the core shooter of the type need adopt spacing ejecting mechanism could produce qualified core smoothly more.The main body parts of the spacing ejecting mechanism of prior art must could be realized ejecting of entire die by the core box body all in the inside of core box body.With regard to the corresponding somatotype area that increases the core box body, need more core box body material to satisfy this ejecting mechanism, thereby the corresponding mold weight that increased has improved manufacturing cost, has reduced the market competitiveness of mould indirectly like this.
Summary of the invention
The utility model technical problem to be solved is: a kind of spacing ejecting mechanism of external that can effectively reduce core box body weight, saving mold materials, reduce die cost is provided.
The utility model addresses the above problem the technical scheme that is adopted: the spacing ejecting mechanism of a kind of external; Comprise that an end is fixedly connected on the upperpush rod of upper plate, is fixedly connected on the upper limit bar cover of core box fixed head, the lower limit bar that is fixedly connected on down the core box fixed head and upper limit bar; Described upperpush rod place described upper limit bar directly over, the activity of described upper limit bar is sleeved on the inner chamber of described upper limit bar cover; And the upper end of described upper limit bar is provided with radial projection, and the inner chamber top of described upper limit bar cover is provided with the stopper slot that matches with described radial projection.
Compared with prior art, the advantage of the utility model is: after penetrating the completion of sand process, upper plate moves to above the core box, and the plunger tip bar contacts with core on this moment, prepares to eject core, and upperpush rod contacts with the upper limit bar simultaneously.Upper plate presses down under the effect of equipment pressure, and the core box body begins uply on this moment, and core is ejected thereupon.And when the radial projection of upper limit bar contacted the stroke of promptly accomplishing setting with the stopper slot of upper limit bar cover, it is up that last core box body also just stops, and so also just played spacing effect.In whole plunger tip and spacing process; The core box mould need not accomplished by more core box body; Particularly concerning the higher core box mould of core box body material requirements, practice thrift many Master Costs, reduced production cost, also improved the market competitiveness of mould simultaneously.
As preferably, described upper limit bar matched in clearance is in described upper limit bar cover inner chamber.
Description of drawings
Fig. 1 is the structural representation of the spacing ejecting mechanism of the utility model external.
In the accompanying drawing: core box fixed head, 5 upper limit bar covers, 5.1 stopper slots, 6 lower limit bars, 7 times core box fixed heads on 1 upper plate, 2 upperpush rods, 3 upper limit bars, 3.1 radial projection, 4.
The specific embodiment
Embodiment to the utility model further describes below in conjunction with accompanying drawing.
Shown in accompanying drawing; The spacing ejecting mechanism of a kind of external; Comprise an end be fixedly connected on the upperpush rod 2 of upper plate 1, be fixedly connected on core box fixed head 4 upper limit bar cover 5, be fixedly connected on down the lower limit bar 6 and the upper limit bar 3 of core box fixed head 4; Described upperpush rod 2 place described upper limit bar 3 directly over, described upper limit bar 3 activities are sleeved on the inner chamber of described upper limit bar cover 5; And the upper end of described upper limit bar 3 is provided with radial projection 3.1, and the inner chamber top of described upper limit bar cover 5 is provided with the stopper slot 5.1 that matches with described radial projection 3.1.
In this specific embodiment, described upper limit bar 3 matched in clearance are in the inner chamber of described upper limit bar cover 5.
After penetrating the completion of sand process, upper plate 1 moves to above the core box, and the plunger tip bar contacts with core on this moment, prepares to eject core, and upperpush rod 2 contacts with upper limit bar 5 simultaneously.Upper plate 1 presses down under the effect of equipment pressure, and the core box body begins uply on this moment, and core is ejected thereupon.And when the radial projection 3.1 of upper limit bar 3 contacted the stroke of promptly accomplishing setting with the stopper slot 5.1 of upper limit bar cover 5, it is up that last core box body also just stops, and so also just played spacing effect.In whole plunger tip and spacing process; The core box mould need not accomplished by more core box body; Particularly concerning the higher core box mould of core box body material requirements, practice thrift many Master Costs, reduced production cost, also improved the market competitiveness of mould simultaneously.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of in the protection domain of the utility model independent claims, being done are all in the utility model protection domain.
Claims (2)
1. spacing ejecting mechanism of external; It is characterized in that: comprise that an end is fixedly connected on the upperpush rod of upper plate (1) (2), is fixedly connected on the upper limit bar cover (5) of core box fixed head (4), the lower limit bar (6) that is fixedly connected on down core box fixed head (4) and upper limit bar (3); Described upperpush rod (2) place described upper limit bar (3) directly over, described upper limit bar (3) activity is sleeved on the inner chamber of described upper limit bar cover (5); And the upper end of described upper limit bar (3) is provided with radial projection (3.1), and the inner chamber top of described upper limit bar cover (5) is provided with the stopper slot (5.1) that matches with described radial projection (3.1).
