The product thimble 17 that top contacts with product 35;
Fix with described product thimble 17 bottoms, and be positioned at the product thimble plate 13 on described injection machine ejector retainner plate 12 tops; And
Auxiliary top ejecting plate 15 between described core fixing plate 33 and described product thimble plate 13.
Further, also comprise support bar 16, described support bar 16 one end are fixed in described core fixing plate 33, and the other end is fixed in described auxiliary top ejecting plate 15.
Further, also comprise resetting-mechanism, described resetting-mechanism comprises:
Bottom is fixed in described product thimble plate 13, and top can be in the interior slip of auxiliary top ejecting plate 15, the sleeve 21 of its inner hollow;
Bottom is fixed in described bottom plate 31, and can be at the sliding bar of described sleeve 21 interior slips;
Be positioned at described auxiliary top ejecting plate 15, cross the sliding pin 23 of described sleeve 21, described sliding pin 23 outsides have inclined-plane; And
Be fixed in described auxiliary top ejecting plate 15, and exceed the gag lever post 24 of described auxiliary top ejecting plate 15, described gag lever post 24 bottoms have the shape matching with described sliding pin 23 outsides.
Beneficial effect: the mode that the product that mold ejection mechanism of the present utility model can make inside have back-off adopts ox horn to enter glue is carried out injection moulding, can improve the production efficiency of product, can ensure again the attractive in appearance of plastic cement products.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Detailed description of the invention
For making those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The mold ejection mechanism of the present embodiment comprises that product 35, employing ox horn enter mold base 32 and the bottom plate 31 of the injection machine 36 of glue mode, core 34, core fixing plate 33, encirclement core 34, are provided with oil cylinder 11 on bottom plate 31.
The top of injection machine thimble 14 contacts with injection machine 36, and bottom is fixed in injection machine ejector retainner plate 12; The top of product thimble 17 contacts with product 35, and bottom is fixed in product thimble plate 13; Product thimble plate is positioned at the upside of injection machine ejector retainner plate 12; Auxiliary top ejecting plate 15 is between core fixing plate 33 and product thimble plate 13; Support bar 16 one end are fixed in described core fixing plate 33, and the other end is fixed in described auxiliary top ejecting plate 15.
When the demoulding, injection machine ejector retainner plate 12 moves upward under the promotion of oil cylinder 11, and drives injection machine thimble 14 upwards injection machine 36 to be ejected to a segment distance, and this process is for the first time and ejects, and is illustrated in figure 2 the structural representation that ejects for the first time rear mechanism.
