Abstract
The invention provides a movable mold with a submarine gate. The movable mold comprises a movable mold plate, and an ejector plate arranged in the movable mold plate, wherein an ejector pin is arranged above the ejector plate; a submarine gate and a fake gate are respectively and symmetrically arranged on two sides of the ejector pin; the end of the fake gate is communicated with the end of the submarine gate; and the fake gate and the submarine gate are obliquely arranged. The application and implementation of the invention have the beneficial effects that according to the design of the fake gate and the inverted conical structure on the top end of the ejector pin, a phenomenon that a product pops up when a material rod is instantaneously ejected out during ejection demolding is avoided.
Description
Technical field
The present invention relates to injection molding apparatus field, particularly relate to a kind of dynamic model and the extrusion method with sub marine gate.
Background technology
Sub marine gate is developed by spot pouring mouth, and it had both overcome the shortcoming of mould with pin point gate complexity, maintains again the advantage of spot pouring mouth.The position that sub marine gate can be arranged is extensive, can be arranged on dynamic model side, also can be arranged on cover half side, both inner surface or the shelter, side of plastic can be arranged on, also can be arranged on the muscle of plastic, post, or be placed on die joint, the knock-pin of mould also can be utilized to arrange cast gate.
For the product adopting sub marine gate mode, when mold ejection mechanism move, material bar, by the effect of thimble ejecting force, is launched to gap, dynamic model side of maybe rebounding, cover half side instantaneously and is not dropped, after may causing mould matched moulds like this, damaged by pressure slide block or die.Therefore, a kind of when mold ejection mechanism move in the urgent need to designing, prevent from material bar to be ejected not dropping thus do not affect the dynamic model structure of matched moulds.
Summary of the invention
The present invention seeks to solve the problems of the technologies described above, and a kind of reasonable in design is provided, prevents from expecting that bar is ejected dynamic model structure and the extrusion method of ejection.In order to achieve the above object, technical solution of the present invention is as follows:
A kind of dynamic model with sub marine gate, comprise moving platen, be arranged on the ejector retainner plate in described moving platen, the top of described ejector retainner plate is provided with thimble, the both sides of described thimble are arranged with sub marine gate and false cast gate respectively, the end of described false cast gate is communicated with the end of described sub marine gate, and false cast gate and sub marine gate are and are obliquely installed.
Preferably, described slanted angle is 45 °.
Preferably, the top of described thimble is a back taper structure.
Present invention further teaches a kind of method with the ejecting product of the dynamic model of sub marine gate, comprise the steps:
S1, injection machine top rod driving ejector retainner plate rise, and material bar ejects by described ejector retainner plate together with product;
S2, ejector retainner plate retreat, and the material bar inclined platform being watered interruption-forming by described vacation arrives to described dynamic model surface, and material bar is taken off by force from the top back taper structure of thimble.
Application of the present invention and enforcement have following beneficial effect: when the design of false cast gate and thimble top back taper structure makes the present invention prevent from when ejection device expecting that bar is ejected instantaneously, product launches.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Detailed description of the invention
Carry out clear, complete description below in conjunction with accompanying drawing by the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
As shown in Figure 1, a kind of dynamic model with sub marine gate, comprise moving platen 1, be arranged on the ejector retainner plate 2 in described moving platen 1, the top of described ejector retainner plate 2 is provided with thimble 3, the both sides of described thimble 3 are arranged with sub marine gate 4 and false cast gate 5 respectively, and the end of described false cast gate 5 is communicated with the end of described sub marine gate 4, and false cast gate and sub marine gate are and are obliquely installed.Described slanted angle is 45 °.The top of described thimble 3 is a back taper structure 6.
Process below by ejecting product of the present invention describes principle of the present invention in detail.Extrusion method of the present invention comprises the steps:
S1, injection machine push rod 7 drive ejector retainner plate 2 to rise, and material bar 8 ejects by described ejector retainner plate 2 together with product 9;
S2, ejector retainner plate 2 retreat, and the material bar inclined platform 10 formed by described false cast gate 5 arrives to described dynamic model surface 11, and material bar is taken off by force from the top back taper structure 6 of thimble 3.
Wherein, in S1 step, because sub marine gate is for being obliquely installed, so product 9 is strong de-when the demoulding, in the process of this strong demoulding, material bar 8 can be pushed up bending by thimble 3.By the time after product 9 all departs from from dynamic model, material bar can produce ejection force, but due to the existence of back taper structure 6, guarantees that material bar 8 can not be ejected from thimble 3.
In addition, due to the existence of false cast gate 5, material bar 8 can be formed material bar inclined platform 10.So when ejector retainner plate 2 retreats in step S2, described material bar inclined platform 10 can arrive to described dynamic model surface 11, material bar is taken off by force from the top back taper structure 6 of thimble 3.
Like this, the present invention just prevents launching of in product stripping process product, prevents further because product launches rear product or material bar impact matched moulds next time.
Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
