Description

A kind of crashproof mould
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of crashproof mould.
Background technology
Present mould has number of different types, wherein a kind of mould is a flexible glue spare of making materials such as plastic material such as PVC, because the small product size that has is smaller, so mould is meticulousr, comprise front template, preceding die, rear pattern plate, back die, thimble, back stitching and ejector retainner plate, because die contacts with the back die before when making plastic cement products, when current die contacts with the back die, thimble is subjected to downward power, because product is smaller, and easy deformation when ejecting, eject the back distortion for fear of product, just need thimble as far as possible greatly and preferably can exceed the external surface of product, consequent problem is exactly thimble and ejection system with after preceding die contacts, cause thimble to be miscued easily, destroy the structure of mould, cause the mould loss ratio than higher.
Summary of the invention
The utility model is finished in order to solve deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, ejecting mechanisms such as cost is lower, thimble and can not be miscued, and repeatedly uses the crashproof mould that also can not damage the mould thimble, can effectively improve die life.
A kind of crashproof mould of the present utility model, comprise front template, preceding die, rear pattern plate, back die, ejector retainner plate, thimble fixed head and back stitching, die is fixed on the described front template before described, described back die is fixed on the rear pattern plate, ejector retainner plate is fixed on the thimble fixed head, described thimble is fixed on the thimble fixed head, described front template is provided with the filling mouth, be equipped with runner on the die behind the described front mould Renhe, it is characterized in that: the sheathed spring in back stitching middle part, described spring is connected with described ejector retainner plate, described thimble fixed head is positioned at described back stitching below and is provided with the elastic force blob of viscose, described back stitching below is stuck in the following glue mouth on described ejector retainner plate bottom gluing mouth and thimble fixed head top, and described elastic force blob of viscose is positioned at gluing mouth and following glue mouth, and described back stitching is stretched out described rear pattern plate height and is higher than described thimble and stretches out described die height afterwards.
A kind of crashproof mould of the present utility model can also be:
Described spring upper end is fixed on the described rear pattern plate, and the lower end of described spring is fixed on the ejector retainner plate.
Be equipped with cooling tube in die, the back die before described.
Thimble fixed head below is connected with ejecting device by push rod.
Die and front template are fixed by screw before described, and described back die and described rear pattern plate are fixed by screw.
Described ejector retainner plate and thimble fixed head are provided with through hole, and described rear pattern plate and described lead to the hole site corresponding position are provided with circular hole, are inserted with a guide pillar in described through hole and the circular hole, and described ejector retainner plate, thimble fixed head move up and down along described guide pillar.
Be provided with back mould mold insert in the die of described back, described back mould mold insert is annular barrel-like structure.
Described thimble fixed head below is provided with and stacks nail.
Crashproof mould of the present utility model, the advantage that has in terms of existing technologies is: owing to be provided with the elastic force blob of viscose below the thimble fixed head is positioned at back stitching, the back stitching below is stuck in the following glue mouth on ejector retainner plate bottom gluing mouth and thimble fixed head top, the elastic force blob of viscose is positioned at gluing mouth and play glue mouth, and the height that back stitching is stretched out described rear pattern plate is higher than described thimble and stretches out described die height afterwards.Simultaneously, pass through a sheathed spring on the back stitching, spring is connected with ejector retainner plate, like this, when current die and back die carry out matched moulds, owing to the elastic force blob of viscose is set below back stitching, under the double action of elastic force blob of viscose and spring, makes back stitching contact with preceding die earlier, and generation cushion effect, drive the thimble fixed head downwards when back stitching is moved back and move downward, drive thimble simultaneously and move downward, the impulsive force when avoiding thimble to contact fast with preceding die, therefore effectively avoided thimble to be miscued, improved the service life of mould, simultaneously because spring and elastic plastic are more cheap, so cost is lower.
