An embodiment of the utility model provides a foaming mould for accomplishing foaming article shaping operation, wherein, foaming article can be auto-parts etc.. As shown in fig. 1 to 3, the foaming mold comprises a movable mold 10 and a fixed mold 20, a cavity 30 is formed when the movable mold 10 and the fixed mold 20 are assembled, the movable mold 10 is provided with a movable mold parting surface 11, the fixed mold 20 is provided with a fixed mold parting surface 21, a circle of sealing groove 22 is arranged on the outer side of the fixed mold parting surface 21, the foaming mold further comprises a sealing element, the sealing element is located in the sealing groove 22, and when the movable mold 10 and the fixed mold 20 are assembled, the sealing element is abutted against the movable mold 10.

When the foaming mold is processed, the movable mold 10 and the fixed mold 20 are matched to form the cavity 30, the foaming material is injected into the cavity 30, then the foaming material is foamed and molded in the cavity 30, the mold is opened after cooling, and parting is carried out through the movable mold parting surface 11 and the fixed mold parting surface 21 so as to take out the molded foaming article. This foaming mold is through setting up round seal groove 22 in the cover half die joint 21 outside, and the sealing member is located the seal groove 22 to support tight movable mould 10 when the compound die, thereby to the better sealed processing that has carried out in the gap between movable mould 10 and the cover half 20, avoid taking place to leak material or air admission die cavity 30 when carrying out the shaping operation and lead to foaming article to appear the overlap or the shaping inhomogeneous, improve the quality of foaming article.

It should be noted that, during processing, the fixed mold 20 is fixed, then the movable mold 10 is moved to a position where the fixed mold 20 is matched, mold closing and injection molding are performed, wherein injection molding needs to be completed within 1s, and air inside the cavity 30 is discharged, so that the cavity 30 is in a vacuum state, thus mold closing force between the movable mold 10 and the fixed mold 20 can be increased, and sealing processing is performed at the mold closing position, thereby preventing air leakage or flash from occurring during foam molding, which affects quality of foam articles, after injection molding is completed, the movable mold 10 is moved by about 1mm to give up a foam space, at this time, foam materials are foam molded in the cavity 30, until molding is completed, the movable mold 10 is cooled and moved again, and then the foam articles are ejected by about 125mm through the ejection assembly, so that the molded foam articles can be taken out.

In the present embodiment, the seal groove 22 is provided along the edge of the fixed mold parting surface 21. Set up round seal groove 22 through the edge at cover half die joint 21, and the sealing member is installed in seal groove 22 to seal the processing to the gap of movable mould die joint 11 with cover half die joint 21 round, sealed effect is better, can prevent effectively that expanded material from appearing a large amount of flashes in the foaming forming process, improves the production quality of foaming article.

It should be noted that, in the present embodiment, the sealing groove 22 is a dovetail groove, and the width of the sealing groove 22 gradually decreases from the groove bottom of the sealing groove 22 to the notch of the sealing groove 22. By adopting the dovetail-shaped sealing groove 22, and the width of the sealing groove 22 is gradually reduced from the groove bottom of the sealing groove 22 to the notch of the sealing groove 22, not only is the sealing element convenient to fixedly mount, but also the sealing element can be prevented from falling off from the sealing groove 22. Of course, in other embodiments, the seal slot 22 is not limited to being a dovetail slot.

In this embodiment, the cross-sectional shape of the seal is circular, and the seal is preferably a weatherstrip. Because the cross-sectional shape of sealing member is circular, be convenient for install the sealing member in seal groove 22 to closely cooperate with seal groove 22, play better sealed effect to the foaming mould. In addition, the sealing strip is convenient to seal, the sealing effect is guaranteed, and the cost is low. Of course, in other embodiments, the cross-sectional shape of the seal is not particularly limited.

In this embodiment, the seal is an interference fit with seal groove 22. Thus, a good sealing effect can be further realized, and the phenomenon that the outside air enters the cavity 30 from the gap between the movable mold 10 and the fixed mold 20 due to a certain gap between the sealing element and the sealing groove 22 is prevented, so that the sealing performance of the foaming mold during mold closing is effectively ensured.

In this embodiment, the foaming mould still includes the ejecting subassembly of the foaming article of being convenient for and the foaming mould drawing of patterns, and ejecting subassembly includes a plurality of lifters, and the foaming mould still includes a plurality of sealing washers, and a plurality of sealing washers are used for a plurality of lifters of sealed respectively. Through also having carried out sealing process at the active position of top member, avoid after the evacuation, the outside air enters into die cavity 30 from these gaps, influences the vacuum effect.

Further, in this embodiment, the foaming mold further includes a plurality of sealing sleeves, and a plurality of sealing rings are respectively sleeved on a plurality of top pieces, and a plurality of sealing sleeves are respectively sleeved outside a plurality of sealing rings. So, carry out double-deck sealed processing through sealing washer and seal cover to the liftout piece promptly, further prevent that the external air from entering into to the die cavity 30 in by the gap department of foaming mould, influence vacuum effect. Therefore, by arranging the sealing element and the sealing ring meter sealing sleeve, the sealing effect of the whole foaming mold can be ensured, and the quality of the foamed article is improved.

In the present embodiment, the foaming mold further includes a wear-resistant block 40, and when the movable mold 10 and the fixed mold 20 are clamped, the wear-resistant block 40 is located between the movable mold 10 and the fixed mold 20. Through setting up wear-resisting piece 40, when movable mould 10 and cover half 20 compound die, movable mould 10 and cover half 20 direct contact not, but realize the butt through a plurality of wear-resisting pieces 40, can cause the damage of movable mould die joint 11 and cover half die joint 21 effectively to avoid still influencing the quality of foaming article because of the damage of foaming mould when moving movable mould 10.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
