Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, provide the utility model discloses a silica gel forming die's an embodiment, including mutual adaptation and carry out the cope match-plate pattern 101 that the hinge connects through hinge structure 103, lower bolster 102, the lower terminal surface of cope match-plate pattern 101 is arranged and is equipped with a plurality of mould cavity 104 of going up, the lower mould cavity 105 that is equipped with a plurality of and last mould cavity 104 corresponding adaptation is arranged to the up end of lower bolster 102, thereby silica gel forming die still includes a plurality of lower mould cavity 105 of locating and the ejecting shell structure of ejecting fashioned silica gel product 107 that can stretch out and draw back from top to bottom, cope match-plate pattern 101, lower bolster 102 lid is gone up mould cavity 104 after closing, lower mould cavity 105, ejecting shell structure between have formed the product die cavity.

The ejection shell structure comprises an ejection shell 106 which is arranged in the lower mold cavity 105 and positioned at the lower end of the molded silica gel product 107, and an ejection spring which is arranged between the ejection shell 106 and the lower mold cavity 105 and can eject the ejection shell 106 upwards so as to eject the silica gel product 107, wherein the ejection shell 106 is made of metal.

The ejection stroke of ejector shell 106 may be adjusted according to process requirements.

When the die is closed, the upper die plate 101 and the lower die plate 102 are covered, the upper die plate 101 has a downward pressing effect on the ejection shell structure, so that the ejection spring contracts and the ejection shell 106 contracts back into the lower die cavity 105, when the die is opened after the molding of the silica gel product 107 is finished, the upper die plate 101 is opened, the ejection spring is released and reset, and the ejection shell 106 is ejected out to eject the molded silica gel product 107, so that the silica gel product 107 can be easily taken out, the demolding process is simple and convenient, and the demolding efficiency is high. This silica gel forming die's structure scientific and reasonable is equipped with ejecting shell structure, can automatic ejecting silica gel product 107 after the die sinking, need not to demold through dragging the product, and the drawing of patterns process is simple and easy convenient, and the drawing of patterns is efficient, and the drawing of patterns effect is ideal, and in addition, the product is automatic ejecting, avoids appearing the deformation problem, and the product disability rate is low, and the product yield is high, and the product steady quality. The method is particularly suitable for the silica gel product 107 with higher thin edge, is beneficial to improving the efficiency of a series of production processes from molding to demolding to product taking out, greatly reduces the rejection rate and improves the yield of products.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
