Abstract

The utility model discloses a kind of pushing block ejecting structure, which includes pushing block, thimble and ejector retainner plate, and the pushing block is located on the die cavity bottom surface of rear cavity, and the head end of the thimble is stretched into rear cavity and is connected with pushing block, and tail end is connected with the ejector retainner plate;The utility model clever structure, rationally, by pushing block come ejecting product, is increased and the contact area between product significantly, and uniform force, ejection effect is good, is prevented effectively from and product occurs and situations such as top is white, top is worn, deforms occur, ensure product quality, yield rate is lifted, production efficiency is high, and overall simple, it is easily achieved, good operating stability, long service life, beneficial to being widely popularized.

Description

Pushing block ejecting structure
Technical field
The utility model is related to die ejector pin technical field, and in particular to a kind of pushing block ejecting structure.
Background technology
Mould is indispensable important equipment in injection mo(u)lding.Injection mo(u)lding is by the plastic material high speed of hot melt state Be injected into there is the closed molding space of required form in mould, after waiting plastic material cooling and solidifying, opening mould will be solid The plastic cement machining object ejection of change, the method to obtain products formed.As injection molding forming method has, shaping expense is low, molding cycle The features such as short, forming process is simple and is easy to the plastic cement products of forming shape complexity, therefore in plastic cement products manufacture field application It is extremely widespread.
Generally, in die sinking, i.e., when caster and male template separate, product is just ejected by thimble immediately, existing Although some thimble structures can meet the functional requirement of ejection, as thimble is less with the contact area of product, easily occur Situations such as top is white, top is worn or deformed so that the yield rate of product is relatively low, and have impact on production efficiency.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of clever structure, rationally, and ejection effect is good, has Effect ensures product quality, lifts the pushing block ejecting structure of yield rate.
For achieving the above object, technical scheme provided by the utility model is:A kind of pushing block ejecting structure, which includes pushing away Block, thimble and ejector retainner plate, the pushing block are located on the die cavity bottom surface of rear cavity, the head end of the thimble stretch into rear cavity and with push away Block is connected, and tail end is connected with the ejector retainner plate.
Used as a kind of improvement of the present utility model, the ejector retainner plate includes panel and base plate, and the tail end footpath of the thimble is convex Increase forms limiting section, and the back side of the panel is provided with the cavity being adapted with the limiting section, and the cavity is provided with and allows thimble The through hole that passes through of head end, the base plate covered at the back side of panel, and by the closure of openings of the cavity.
Used as a kind of improvement of the present utility model, the back side of the ejector retainner plate is provided with circular jacking block.
Used as a kind of improvement of the present utility model, the peripheral position of the pushing block is provided with installing hole, and the installing hole is provided with Screw, and the screw hole being adapted with the screw is provided with the head end face of the thimble.
The beneficial effects of the utility model are:The utility model clever structure, rationally, by pushing block come ejecting product, greatly Big to increase and the contact area between product, and uniform force, ejection effect is good, is prevented effectively from and product occurs and occur that top is white, top Situations such as wearing, deform, it is ensured that product quality, lifts yield rate, and production efficiency is high, and overall simple, it is easy to accomplish, work is steady It is qualitative good, long service life, beneficial to being widely popularized.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Specific embodiment
Referring to a kind of pushing block ejecting structure that Fig. 1 and Fig. 2, the present embodiment are provided, which includes pushing block 1, thimble 2 and ejector retainner plate 3, the pushing block 1 is located on the die cavity bottom surface of rear cavity 4, and the head end of the thimble 2 is stretched into rear cavity 4 and is connected with pushing block 1, Specifically, the peripheral position in the pushing block 1 is provided with installing hole 11, and the installing hole 11 is provided with screw 12, and in the thimble 2 Head end face be provided with the screw hole being adapted with the screw 12.The tail end of the thimble 2 is connected with the ejector retainner plate 3.
Referring to Fig. 2, the ejector retainner plate 3 includes panel 31 and base plate 32, and the convex increase in tail end footpath of the thimble 2 forms spacing Portion 21, the back side of the panel 31 are provided with the cavity 311 being adapted with the limiting section 21, and the cavity 311 is provided with and allows thimble 2 The through hole that passes through of head end, the base plate 32 fixed by screw 33 and covered at the back side of panel 31, and by the cavity 311 Closure of openings.Preferably, limiting section 21 is provided with concave surface, and the convex surface being adapted with the concave surface is provided with the cavity 311, is kept away Exempt from 2 rotation of thimble, further lift ejection effect.
Preferably, circular jacking block 5 is provided with the back side of the ejector retainner plate 3, and it is convenient to be connected with push rod, lift the steady of ejection It is qualitative.
During work, by pushing block 1 come ejecting product 6, increase significantly and the contact area between product 6, and uniform force, Ejection effect is good, is prevented effectively from and situations such as appearance of product 6 top is white, top is worn, deforms occurs, it is ensured that product quality, lifts yield rate, And good operating stability, long service life, greatly improve production efficiency.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality The mode of applying is changed and is changed.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right Some modifications and changes of the present utility model should also be as falling in scope of the claims of the present utility model.Additionally, to the greatest extent Some specific terms used in pipe this specification, but these terms are merely for convenience of description, not to the utility model Constitute any restriction.As described in the utility model above-described embodiment, using obtained from same or similar structure other The mechanism of structure, in the utility model protection domain.
