Abstract
The present invention provides a kind of blow molded product and reinforces local wall thickness mechanism and its application method, which is characterized in that including blow mold and actuator cylinder, the blow mold includes drawing mechanism, and the drawing mechanism is connect with actuator cylinder.In blow molded product molding, using the preparatory method for drawing material, part sizing material is pull towards mold groove position in advance, thus reach general thickness it is constant in the case where, increase product wall thickness at product boss.
Description
Technical field
The present invention relates to a kind of blow mold and application methods, and in particular to a kind of blow molded product reinforcement local wall thickness mechanism
And its application method.
Background technique
Also referred to as hollow blow molding, a kind of plastic working method quickly grown.Blow molding process during World War II,
Start for producing low density polyethylene (LDPE) bottle.Fifties later period, birth and blow molding machine with high density polyethylene (HDPE)
Development, blow molding technology are widely applied.The volume of hollow container has used computer control up to thousands of liters, some production
System.Plastics suitable for blow molding have polyethylene, polyvinyl chloride, polypropylene, polyester etc., and the hollow container of gained is widely used as industry
Packing container.According to parison production method, blow molding can be divided into extrusion-blown modling and injection-blow molding, and what new development was got up has multilayer to blow
Modeling and stretch-blow.
For part blow molded product because structure is limited, local wall thickness can be partially thin, but product function requires have wall thickness requirement sometimes, adopts
Method is Integral upset product wall thickness.It will increase the weight of product in this way and extend the molding cycle of product.Lead to product
The unnecessary increase of cost.Therefore a kind of blow molded product is needed to reinforce the method for local wall thickness.
Summary of the invention
Above-mentioned to solve the problems, such as, the purpose of the present invention is to provide a kind of blow molded products to reinforce local wall thickness mechanism
And its part sizing material, using the preparatory method for drawing material, is pull towards mold groove position in blow molded product molding by application method in advance
Set, thus reach general thickness it is constant in the case where, increase product boss at product wall thickness.
In order to achieve the above objectives, the technical scheme is that
A kind of blow molded product reinforcement local wall thickness mechanism, which is characterized in that including blow mold and actuator cylinder, the blow molding die
Tool includes drawing mechanism, and the drawing mechanism is connect with actuator cylinder.
As a further improvement of the foregoing solution, the drawing mechanism head be equipped with boss, the blow mold be equipped with
The extraction road of drawing mechanism cooperation.The setting can effectively limit the scope of activities of drawing mechanism, avoid excessively sending outside.
As a further improvement of the foregoing solution, the blow mold is equipped with the stomata for leading to extraction road.The setting is conducive to
The activity of drawing mechanism.
As a further improvement of the foregoing solution, the drawing mechanism is core pulling needle.
A kind of blow molded product reinforces the application method of local wall thickness mechanism, which comprises the following steps: a molding,
Ingredient contacts drawing mechanism when molding, and drawing mechanism is sent outside, embryo material is taken out of；B, it forms, drawing mechanism pushes back when molding, by a
In the embryo material taken out of push back.When molding, after being blow molded embryo material arrival certain position, core pulling needle contacts embryo material, and embryo material itself glues
Property, when embryo material is sticked to core pulling needle top surface, with the progress of molding, core pulling needle is pushed back, and drive the material of adhesion to push back mold together, from
And the wall thickness of product part is increased when forming.
Detailed description of the invention
Fig. 1 is a kind of blow molded product reinforcement local wall thickness mechanism structure schematic diagram provided by the embodiment of the present invention.
Wherein:
1, blow mold；2, drawing mechanism；3, boss；4, road is extracted out；5, stomata.
Specific embodiment
Below with reference to embodiment and attached drawing to the specific effect of the design of the invention, specific structure and generation into
Row is removed, is completely described, adequately to understand the purpose, feature and effect of the invention.Every skill of the invention
Art feature, the premise of not conflicting conflict can be with combination of interactions.
Embodiment one, referring to Fig. 1, a kind of blow molded product reinforces local wall thickness mechanism, which is characterized in that including blow mold
1 and actuator cylinder, the blow mold 1 includes drawing mechanism 2, and the drawing mechanism 2 is connect with actuator cylinder.
As a further improvement of the foregoing solution, 2 head of drawing mechanism is equipped with boss 3, and the blow mold 1 is equipped with
The extraction road 4 cooperated with drawing mechanism 2.The setting can effectively limit the scope of activities of drawing mechanism 2, avoid being outside one's consideration
It send.
As a further improvement of the foregoing solution, the blow mold 1 is equipped with the stomata 5 for leading to extraction road 4.Setting benefit
In the activity of drawing mechanism 2.
As a further improvement of the foregoing solution, the drawing mechanism 2 is core pulling needle.
Embodiment two, referring to Fig. 1, a kind of blow molded product reinforces the application method of local wall thickness mechanism, which is characterized in that packet
Include following steps: a molding, ingredient contacts drawing mechanism 2 when molding, and drawing mechanism 2 is sent outside, embryo material is taken out of；B, it forms, molding
When drawing mechanism 2 push back, the embryo material taken out of in a is pushed back.When molding, after being blow molded embryo material arrival certain position, core pulling needle is connect
Embryo material is touched, the viscosity of embryo material itself, when embryo material is sticked to core pulling needle top surface, with the progress of molding, core pulling needle is pushed back, and drives adhesion
Material push back mold together, to increase the wall thickness of product part when forming.
It should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting.Although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to the technology of invention
Scheme is modified or replaced equivalently, and without departing from the range of technical solution of the present invention, should all be covered in power of the invention
In sharp claimed range.
