Abstract
Description
Technical field
It the utility model is related to technical field of mold, and in particular to a kind of pneumatic jack assisted demoulding knot applied in a mold Structure.
Background technology
Mould is indispensable important equipment in injection molding.Injection molding is by the plastic material high speed of the state of hot melt Be injected into the closed molding space in mould with required shape, after waiting plastic material to cool and solidify, opening mould will be solid The plastic cement machining object ejection of change, to obtain the method for products formed.Because injection molding forming method has, shaping expense is low, molding cycle The features such as short, forming process is simple and is easy to forming shape complicated plastic cement products, therefore in plastic cement products manufacturing field application It is extremely widespread.
With social progress, living standard improves, and people are more and more to daily plasthetics, and arise at the historic moment plastic cement products Species is more and more.Such as the product of plastic barrel etc turns into the necessity of people's daily life.
Because bucket class product belongs to deep chamber product, need smoothly to be stripped from mould in manufacturing process, due to traditional work Skill is directly to release product by push pedal, and forming vacuum between product and mould during the demoulding makes product ejection deformation or even push up bad cause Product is unqualified, influences the quality of product.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, rationally, can be lifted take off Fruit is imitated, the pneumatic jack assisted demoulding structure of product quality is effectively ensured.
To achieve the above object, technical scheme provided by the utility model is：A kind of pneumatic jack assisted demoulding structure, it is wrapped Template, pneumatic jack main body, air valve and elasticity part are included, the cavity surface of the template is provided with air intake duct, and the upper end of the air intake duct is set There is the assembly cavity being adapted with pneumatic jack main body, the pneumatic jack main body is located in assembly cavity, and provided with the outlet being connected with air intake duct Road, the upper end of the gas off-take are provided with back taper valve pocket, and lower end is radially enlarged to form adaptation chamber, and the elasticity part is positioned at adaptation chamber Interior, the air valve is located in back taper valve pocket, and the air valve bottom is provided with and stretches into adaptation intracavitary, and is connected with elasticity part lower end The connecting rod connect.
As a kind of improvement of the present utility model, the elasticity part is spring or elastic rubber set.
As a kind of improvement of the present utility model, the bottom of the pneumatic jack main body is provided with external screw thread, and in the assembly cavity Inwall be provided with the internal thread that is adapted with external screw thread.
The beneficial effects of the utility model are：The utility model smart structural design, rationally, by entering before mould ejection Air flue is charged into gases at high pressure, and air valve is opened under the influence of air pressure, and gas quickly enters die cavity, and gas pushes up again after entering die cavity Go out, product is ejected and will not deformed when antivacuum, is easier to be stripped from die cavity by product after gas expansion, is made stripping action more It is smooth, and product quality is effectively ensured；After the demoulding, air valve is repositioned to original under the elastic force effect of elasticity part when stopping inflation Position, whole workflow action is smooth, and robust motion is good, and reliable high, overall structure is simple in addition, effectively simplifies mould knot Structure, cost is low, is used beneficial to being widely popularized.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial structurtes enlarged diagram in the utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of pneumatic jack assisted demoulding structure of the present embodiment offer, it includes template 1, pneumatic jack main body 2nd, air valve 3 and elasticity part 4, the cavity surface of the template 1 are provided with air intake duct 11, and the upper end of the air intake duct 11 is provided with and pneumatic jack The assembly cavity that main body 2 is adapted, specifically, external screw thread is provided with the bottom of the pneumatic jack main body 2, and in the assembly cavity Wall is provided with the internal thread being adapted with external screw thread, and assembling is simple, it is easy to accomplish.
The pneumatic jack main body 2 is located in assembly cavity, and provided with the gas off-take that is connected with air intake duct 11, the gas off-take it is upper End is provided with back taper valve pocket, and lower end is radially enlarged to form adaptation chamber, and the elasticity part 4 is positioned at adaptation intracavitary, 3, the air valve In in back taper valve pocket, and the bottom of air valve 3 is provided with and stretches into adaptation intracavitary, and the connecting rod being connected with the lower end of elasticity part 4 5。
In the present embodiment, the elasticity part 4 is preferably spring, and in other embodiments, the elasticity part 4 can be elastic force Rubber sleeve.
During production, gases at high pressure are charged into by air intake duct 11 before mould ejection, air valve 3 is opened under the influence of air pressure, Gas quickly enters die cavity, and gas is ejected again after entering die cavity, and product 6 is ejected and will not deformed when antivacuum, passes through gas expansion Product 6 is easier to be stripped from die cavity afterwards, makes stripping action more smoothly, and product quality is effectively ensured；After the demoulding, stop inflation When air valve 3 be repositioned to origin-location under the elastic force effect of elasticity part 4, whole workflow acts smooth, robust motion It is good, it is reliable high.
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 realities The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model Form any restrictions.As described in the utility model above-described embodiment, using other obtained from same or similar structure Mould, in scope of protection of the utility model.
