Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of delayed goring mould.
Background technology
Mould is indispensable important equipment in injection mo(u)lding.Injection mo(u)lding is had in the airtight molding space of required form being injected in mould of the plastic material of hot melt state high speed, after waiting plastic material cooling curing, opens mould and the plastic cement machining object of solidification ejected, to obtain the method for products formed.There is due to injection molding forming method the features such as the plastic cement products that shaping expense is low, molding cycle is short, forming process is simple and be easy to forming shape complexity, therefore manufacture field application at plastic cement products very general.
Generally, when die sinking, namely when caster and male template are separated, product just ejects by thimble immediately, complete in time delay, product cools without time enough, in knockout course, product easily occurs that pushing up white phenomenon occurs, and also can be pulled once in a while, has influence on the quality of product.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, provides a kind of simple and reliable for structure, can delayed goring, avoids occurring the phenomenons such as top is white, ensures the delayed goring mould of product quality.
For achieving the above object, technical scheme provided by the utility model is: a kind of delayed goring mould, it also comprises upper mounted plate, caster, male template, upper ejector retainner plate, lower ejector retainner plate, bottom plate, flat thimble and dome pin, fixed plate, caster, male template, upper ejector retainner plate, lower ejector retainner plate and bottom plate are by order is stacked successively from top to bottom, and have gap between described lower ejector retainner plate and bottom plate, flat thimble and dome pin interval are arranged side by side, and upper end is successively through lower ejector retainner plate, upper ejector retainner plate and male template, lower end is pressed on described bottom plate, described flat thimble and dome are formed for the position radial protrusion should gone up between ejector retainner plate and lower ejector retainner plate and drive boss, on this, the lower surface of ejector retainner plate is provided with the upper movable chamber suitable with this driving boss, the upper surface of described lower ejector retainner plate is provided with the lower movable chamber suitable with this driving boss, the degree of depth sum in this lower movable chamber and upper movable chamber is greater than the length of described driving boss.
Improve as one of the present utility model, the flat-shaped body that described flat thimble comprises cylinder and is connected with this cylinder, described driving boss is arranged on described cylindrical lower position.
Improve as one of the present utility model, the degree of depth in the lower movable chamber of matching with the driving boss of described flat thimble is greater than the degree of depth in lower movable chamber with another.
The beneficial effects of the utility model are: the utility model structure is ingenious, reasonable, when caster separates with male template, under pressure retracts effect, upper ejector retainner plate ejects together with lower ejector retainner plate, and due to the degree of depth sum driving the length of boss to be less than lower movable chamber and lower movable chamber, namely lower movable chamber and driving boss have gap between having, fail to force in time and drive on boss, flat thimble and dome pin keep transfixion, have certain time-delay effect, and this delay time section cools for product just; Namely distance is ejected when being greater than lower movable chamber and driving the gap between boss, product ejects by flat thimble and dome pin, effectively can solve ejection process product and occur albefaction problem, ensure product quality, and stripping result is good, good stability, reliability is high, and overall simple, be easy to realize, cost is low, is beneficial to extensive popularization.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the decomposition texture schematic diagram of upper and lower ejector retainner plate in Fig. 1.
Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of delayed goring mould that the present embodiment provides, it also comprises upper mounted plate 1, caster 2, male template 3, upper ejector retainner plate 4, lower ejector retainner plate 5, bottom plate 6, flat thimble 7 and dome pin 8, fixed plate 1, caster 2, male template 3, upper ejector retainner plate 4, lower ejector retainner plate 5 and bottom plate 6 by order is stacked successively from top to bottom, and have gap between described lower ejector retainner plate 5 and bottom plate 6, and flat thimble 7 and dome pin 8 interval are arranged side by side, and upper end is successively through lower ejector retainner plate 5, upper ejector retainner plate 4 and male template 3, lower end is pressed on described bottom plate 6, and described flat thimble 7 and the upper position radial protrusion between ejector retainner plate 4 and lower ejector retainner plate 5 of dome pin 8 correspondence are formed and drive boss 71, 81, on this, the lower surface of ejector retainner plate 4 is provided with and this driving boss 71, 81 suitable upper movable chambeies 41, 42, the upper surface of described lower ejector retainner plate 5 is provided with the lower movable chamber 51 suitable with this driving boss, 52, the degree of depth sum in this lower movable chamber 41 and upper movable chamber 51 is greater than the length of described driving boss 71.The degree of depth sum in this lower movable chamber 42 and upper movable chamber 52 is greater than the length of described driving boss 81.
Preferably, the degree of depth in the lower movable chamber 51 of matching with the driving boss 71 of described flat thimble 7 is greater than the degree of depth with lower movable chamber 52.Adopt the eject step of the flat thimble of this structure 7 slower compared with ejecting of dome pin 8.Because the face area of dome pin 8 is larger than the face area of flat thimble 7, namely comparatively large with the contact area of product, not easily there is the phenomenon that top is white; And utilize the ejection cycle between flat thimble 7 and dome pin 8 poor, allow product cool further, then flat thimble 7 contacts with product again, effectively stops the phenomenon occurring that top is white, ensures product quality.Be provided with flat thimble 7 and dome pin 8 simultaneously, be applicable to longer and narrower, that wall is thin product.
Concrete, the flat-shaped body 73 that described flat thimble 7 comprises cylinder 72 and is connected with this cylinder, described driving boss 71 is arranged on the lower position of described cylinder 72.
During work, when caster 2 separates with male template 3, under pressure retracts effect, upper ejector retainner plate 4 ejects together with lower ejector retainner plate 5, and due to the degree of depth sum driving the length of boss to be less than lower movable chamber and lower movable chamber, namely lower movable chamber and driving boss have gap between having, fail to force in time and drive on boss, flat thimble 7 and dome pin 8 keep transfixion, have certain time-delay effect, and this delay time section cools for product just; Namely eject distance when being greater than lower movable chamber and driving the gap between boss, product ejects by flat thimble 7 and dome pin 8, effectively can solve ejection process product and occur albefaction problem, and ensure product quality, and stripping result is good, good stability, reliability is high.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.As described in the utility model above-described embodiment, adopt structure same or analogous with it and the mould of other structure obtained, all in the utility model protection domain.
