Abstract
The utility model discloses a demoulding mechanism that blows of thin wall product is provided with main air flue in the mould of back, main air flue is located the below of product, main air flue is blown to the inside of product, the outside at the back mould still is provided with a plurality of supplementary air flues, supplementary air flue sink into in by the pneumatic means drive or expose in the back mould outside, expose in the back mould outside the play air cock of supplementary air flue is aimed at the back die cavity that product bottom edge was located. The utility model discloses can realize shortening the injection cycle to the fast and stable drawing of patterns of thin wall product, improve production efficiency.
Description
Technical field
The utility model relates to mould structure technical field, particularly a kind of air blowing mould release mechanism of thin-wall product.
Background technology
The injection molding mechanism for thin-wall product conventional at present, general is all that thin-wall product ejects by the inner air flue of a deisgn product, product likely can be caused to glue, and gas that rear mold and air flue produce by boasting can puncture thin-wall product, so there is a lot of unstable possibility, extend injection cycle, add the cost to mold repair, even reduce production efficiency.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of air blowing mould release mechanism of thin-wall product, can realize the fast and stable demoulding to thin-wall product, shortens injection cycle, enhances productivity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of air blowing mould release mechanism of thin-wall product, is provided with main airway in rear mold, and described main airway is positioned at the below of product, blows in the inside of described main airway to product; Some auxiliary ports are also provided with in the outside of rear mold, described auxiliary port sinks into or is exposed to outside described rear mold in being driven by pneumatic means, and the outlet nozzle being exposed to the described auxiliary port outside described rear mold aims at the rear die cavity residing for described product bottom margin.
In technique scheme, described main airway comprises the first air flue and the second air flue, and described first air flue, the second air flue externally to distribute setting along the center line of product successively.
In technique scheme, the inner bottom part of described first air flue to product is blown, and the inwall of described second air flue to product is blown.
In technique scheme, described auxiliary port is wrapped up by sleeve pipe, and sleeve pipe is provided with opening and exposes described outlet nozzle.
The beneficial effects of the utility model are: increase the auxiliary port of blowing to product bottom margin, time product is ejected by main airway insufflation part, can be blown by the rear die cavity position of auxiliary port to product bottom margin, the gas blowing to this rear die cavity position rises through bounce-back and promotes product bottom margin, enables product be blown rear mold instantaneously and drops.Overall structure is simple, a maintenance difficulty is installed little, the automatic demoulding to thin-wall product can be realized effectively rapidly, shorten injection cycle and reduce the possibility of gluing rear mold, and main airway jet intensity only need product to eject part the bottom margin of product is departed from after die cavity, decrease the possibility punctured by product because the jet mistake of air flue is strong, substantially increase production stability and the reliability of product, enhance productivity and reduce maintenance cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of air blowing mould release mechanism of thin-wall product, is provided with main airway in rear mold 1, and this rear mold 1 is punch, and product 9 is have flange in bowl-shape edge; Described main airway is positioned at the below of product 9, blows in the inside of described main airway to product 9; Some auxiliary ports 2 are also provided with in the outside of rear mold 1, described auxiliary port 2 sinks into or is exposed to outside described rear mold 1 in being driven by pneumatic means, and the outlet nozzle 3 being exposed to the described auxiliary port 2 outside described rear mold 1 aims at the rear die cavity 4 bottom described product residing for 5 edges.Some auxiliary ports 2 also circumferentially can distribute along the surrounding of rear mold 1, and four points that also can only arrange between four equities carry out blowing.
Wherein, described main airway comprises the first air flue 6 and the second air flue 7, and described first air flue 6, second air flue 7 externally to distribute setting along the center line of product 9 successively.Preferred first air flue 6 and the second air flue 7 can circumferentially be arranged respectively, form being uniformly distributed of opposing product 9, also can realize being uniformly distributed the active force of product 9, avoid product 9 is blown partially when air blowing.
Wherein, the inner bottom part of described first air flue 6 pairs of products 9 is blown, and the inwall of described second air flue 7 pairs of products 9 is blown simultaneously.The position of blowing to product 9 is evenly distributed on whole product 9, makes product 9 uniform force, the stably demoulding can be realized, ensure demoulding quality.
Wherein, described auxiliary port 2 is wrapped up by sleeve pipe 8, and sleeve pipe 8 is provided with opening and exposes described outlet nozzle 3.In order to ensure that auxiliary port 2 can not impact product 9 in injection moulding process, sleeve pipe 8 is wrapped up auxiliary port 2, and drives auxiliary port 2 to be elevated, when mold-closing injection, auxiliary port 2 is concealed in rear mold 1, when when die sinking, auxiliary port 2 stretches out rear mold 1.Sleeve pipe 8 is also provided with the projection for limiting boot 8 stroke, this projection is stuck in the groove of the vias inner walls of described this sleeve pipe 8 accommodating.
Above embodiment is just to illustrate instead of restriction the utility model, therefore all equivalences done according to the method described in the utility model patent claim change or modify, and are included in the utility model patent claim.
