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 mold cavity 30 is formed when the movable mold 10 and the fixed mold 20 are closed, 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 groove 211 is formed at the joint of the fixed mold parting surface 21 and the mold cavity 30, a protrusion 111 matched with the groove 211 is formed at the joint of the movable mold parting surface 11 and the mold cavity 30, and the protrusion 111 moves in the groove 211.

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 movable mold 10 is moved, the protrusion 111 moves for a certain distance in the groove 211, meanwhile, 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 that the molded foaming article can be taken out. The movable die 10 and the fixed die 20 of the foaming die adopt the mode that the protrusion 111 is matched with the groove 211, and after injection molding, the movable die 10 can move to give out a foaming space without influencing the molding of a foaming article in the cavity 30, so that the special molding requirement of the foaming article is met.

It should be noted that, during processing, the fixed mold 20 is fixed, then the movable mold 10 is moved to a position where it fits with the fixed mold 20, and then mold closing and injection molding are performed, wherein injection molding needs to be completed within 1s, after injection molding is completed, the movable mold 10 is moved by about 1mm to make a foaming space, at this time, the foaming material is foamed and molded in the cavity 30, and after molding is completed, cooling is performed, and the movable mold 10 is moved again, so that the molded foamed article is taken out. When forming the foaming article promptly, consider the demand in foaming space, one section parting line is drawn off to the side down earlier need be done to the movable mould parting surface 11 of foaming mould, and the movable mould parting surface 11 is drawn off to the level again, however, the movable mould parting surface 11 of ordinary mould is directly drawn off the movable mould parting surface 11 from the parting line is drawn off to the level, avoids damaging movable mould parting surface 11, and the movable mould parting surface 11 of ordinary mould does not need hard mold design, changes processing.

When the movable mold 10 is moved to give way to the foaming space, only the foaming material foaming forming space is reserved between the protrusion 111 and the groove 211, so that the formed foaming article meets the processing requirement, the phenomenon of flash is avoided, and the rejection rate is reduced.

Further, in the present embodiment, the protrusion 111 is clearance-fitted with the groove 211. Because the bulge 111 and the groove 211 are in clearance fit, the abrasion of the parting surface 11 of the movable mold and the parting surface 21 of the fixed mold during mold closing and mold opening can be avoided, and the molding quality of the foamed article is influenced. In addition, the matching precision of the movable mold 10 and the fixed mold 20 at the position of the protrusion 111 and the groove 211 is extremely high, so that the movable mold 10 is prevented from being damaged by insertion, and the movable mold parting surface 11 and the fixed mold parting surface 21 are prevented from being damaged.

It should be noted that, in the present embodiment, the groove 211 is a straight-slope groove 211. Through adopting the straight slope recess 211 to give up 1 mm's foaming space, the foaming of being convenient for produces, and also simpler in the design of mould. In addition, because the part is also the sealing part, the movable mold 10 needs to be completely and closely attached to the fixed mold 20 all the time, so that the phenomenon that the quality of the foamed article is affected by flash or material shortage of the foamed article due to material leakage is prevented. Of course, in other embodiments, the recess 211 is a ramp recess 211.

In the present embodiment, the outer side of the fixed mold 20 has a first inclined surface 22 that can be guided, and the inner side of the movable mold 10 has a second inclined surface 12 that can be guided, so that the movable mold 10 and the fixed mold 20 are matched through the first inclined surface 22 and the second inclined surface 12 to complete mold clamping. The first inclined surface 22 and the second inclined surface 12 are matched with each other, so that the movable die 10 is guided in the moving process of the movable die 10, the processes of closing and opening the foaming die are facilitated, and the forming quality of the foaming article is improved.

In the present embodiment, the movable mold 10 is provided with four guide slots 13, and the fixed mold 20 includes four guide posts 23 respectively engaged with the four guide slots 13, so that the movable mold 10 and the fixed mold 20 complete mold clamping through engagement of the four guide slots 13 and the four guide posts 23. Through setting up four guide posts 23 and four guide ways 13 to further leading when the compound die, guarantee that movable mould 10 moves smoothly to the position of closing with the cover half 20, avoid movable mould 10 to take place crooked at the in-process of compound die with cover half 20, promote the production efficiency of foaming article, guarantee the smooth shaping of foaming article.

Further, in the present embodiment, four guide grooves 13 and four guide posts 23 are provided at the corners of the movable mold 10 and the fixed mold 20, respectively. Therefore, the movable die 10 can be guided in the moving process of the movable die 10, the space of the whole foaming die is more reasonable, and the foaming molding of the foaming material in the cavity 30 is prevented from being influenced.

In this embodiment, the foaming mold further includes a wear-resistant block 40, and the wear-resistant block 40 is located on the first inclined surface 22. Because the plurality of wear-resisting blocks 40 are arranged on the first inclined surface 22, when the movable die 10 and the fixed die 20 are assembled, the second inclined surface 12 is not in direct contact with the first inclined surface 22, but is in butt joint through the plurality of wear-resisting blocks 40, so that the damage to a foaming die caused when the movable die 10 is moved is effectively avoided, and the influence on the quality of a foaming article due to the damage to the foaming die is also avoided.

In this embodiment, the foaming mold further includes a balance weight 50, the balance weight 50 is mounted on the movable mold 10, and when the movable mold 10 and the fixed mold 20 are closed, the movable mold 10 abuts against the fixed mold 20 through the balance weight 50. Specifically, in the present embodiment, the weight 50 is a high-hardness weight 50, and the high-hardness weight 50 is installed between the movable mold 10 and the fixed mold 20 to play a role in buffering a force, so that damage to the movable mold parting surface 11 or the fixed mold parting surface 21 due to a large mold clamping force when the movable mold 10 and the fixed mold 20 are clamped can be effectively avoided.

Further, in the present embodiment, the foaming mold includes a plurality of weights 50, and when the movable mold 10 and the fixed mold 20 are clamped, the movable mold 10 abuts against the fixed mold 20 through the plurality of weights 50. Thus, the balance weights 50 with high hardness can play a good role in buffering between the movable mold 10 and the fixed mold 20, thereby protecting the foaming mold and prolonging the service life of the foaming mold.

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.
