Abstract
The invention discloses a method for molding soft plastic on a hard plastic product and a mold design method thereof. A molded product molded by casting the soft plastic on the hard plastic product by adopting a mold designed and manufactured by the method can prevent the soft plastic from being extruded from a contact gap between the soft plastic and the hard plastic, prevent the generation of flash and reduce a flash processing process. The mold design method is characterized by comprising the following steps of: manufacturing a hard plastic casting mold; casting the hard plastic product by using the hard plastic casting mold; realizing molding the soft plastic on the hard plastic product (namely coating the soft plastic out of the hard plastic product) by using the hard plastic casting mold to obtain a soft plastic-coated product; measuring the thickness of the raw edges of the soft plastic-coated product; and adding hard plastic strips at the sealing edges of the soft plastic and the hard plastic in the hard plastic casting mold to manufacture a soft plastic mold. The invention also provides a method for producing the molded product by using the soft plastic mold. The method comprises the following steps of: casting the hard plastic product by using the hard plastic casting mold; and molding the soft plastic on the hard plastic product by using the soft plastic mold (namely coating the soft plastic out of the hard plastic product) to obtain the molded product.
Description
Technical field
The present invention relates to the technical field that injecting products is produced, be specially a kind of flexible glue forming method and die design method thereof on the ebonite product.
Background technology
In the production of injecting products; shaped article often can occur is the product of flexible glue moulding on the ebonite product (ebonite product outsourcing flexible glue); because the shrinkage factor of plastics is inconsistent; flexible glue can be extruded from the contact gap of flexible glue and ebonite; certain thickness burr appear; affect the attractive in appearance of product, will again process burr, increased manufacturing procedure.
Summary of the invention
For the problems referred to above, the invention provides a kind of flexible glue forming method and die design method thereof on the ebonite product, at flexible glue on the ebonite product during moulding (ebonite product outsourcing flexible glue), can prevent that flexible glue from extruding from the contact gap of flexible glue and ebonite, prevent the generation of overlap, reduced the overlap treatment process.
Its technical scheme is such: it is characterized in that comprising the following steps:
(1), produce the ebonite injection mold of ebonite product;
(2), water with the ebonite injection mold and outpour the ebonite product;
(3), realizing flexible glue moulding on the ebonite product (ebonite product outsourcing flexible glue) on the ebonite injection mold of ebonite product in step (1), obtain wrapping the flexible glue product;
The burr thickness of the bag flexible glue product that (4), obtains in measuring process (3);
(5), to add width be 0.8mm-1.0mm at the sealing edge of flexible glue and ebonite in the ebonite injection mold in step (1), thickness is the ebonite bar that burr thickness adds 0.01mm-0.1mm (preferred 0.05mm), obtains soft jelly mould;
A kind of flexible glue is forming method on the ebonite product, it is characterized in that: the method for producing shaped article with described soft jelly mould comprises the following steps:
(1), water with described ebonite injection mold and outpour the ebonite product;
(2), the ebonite product in step (1) is being carried out flexible glue moulding on the ebonite product (ebonite product outsourcing flexible glue) on described soft jelly mould, obtain the shaped article of moulding flexible glue on the ebonite product.
The mould that in the present invention, the method for designing of the above-mentioned mould of employing processes, because the sealing edge of flexible glue in soft jelly mould and ebonite is processed with the ebonite bar, the gap at the sealing edge of the ebonite that contraction distortion that can local equalize's ebonite product produces and flexible glue, the processing flexible glue is on ebonite during shaped article, the shaped article of the flexible glue that processes moulding on the ebonite product (ebonite product outsourcing flexible glue), can effectively prevent the generation of burr, reduce the manufacturing procedure that burr are processed, improved operating efficiency.
The specific embodiment
Shaped article is the method for designing of the mould of flexible glue moulding on the ebonite product (ebonite product bag flexible glue) product: at first according to the ebonite product design, produce the ebonite injection mold, water and outpour the ebonite product; Then realize flexible glue moulding on the ebonite product (ebonite product outsourcing flexible glue) on aforesaid ebonite injection mold, during the cast flexible glue, because the shrinkage factor of plastics is inconsistent, the sealing edge of ebonite and flexible glue is gapped, the flexible glue plastics can be extruded from the gap at the sealing edge of ebonite and flexible glue, produce certain thickness burr, measure burr thickness, to add width be 0.8mm-1.0mm at the sealing edge of flexible glue and ebonite in original ebonite injection mold afterwards, thickness is the ebonite bar that burr thickness adds 0.01mm-0.1mm (preferred 0.05mm), obtains soft jelly mould; Again water with the ebonite injection mold and outpour the ebonite product, put into soft jelly mould and carry out flexible glue moulding on the ebonite product (ebonite product outsourcing flexible glue) again watering the ebonite product that outpours, obtain the shaped article of flexible glue moulding on the ebonite product, because the sealing edge of flexible glue and ebonite in ebonite injection moulding soft jelly mould is processed with the ebonite bar, the sealing edge of the ebonite that contraction distortion that can local equalize's ebonite product produces and flexible glue is gapped, thereby prevented the generation of burr, reduce the manufacturing procedure that burr are processed, improved operating efficiency.
