Abstract
The utility model discloses a kind of plastic straightening structures, it is related to plastic field, including pedestal and the thin-walled mount structure being set on the base; thin-walled mount structure is surrounded by the wall portion of front, the short curved wall portion of two sides and subsequent long curved wall portion, it is characterised in that: the shape of the wall portion of injection molding after processing is completed is the arc of convex.The utility model is designed as the arc of convex by the shape of the wall portion by injection molding after processing is completed, it concaves after the thermal stress release that plastic generates in process, so that the shape of deformed wall portion becomes straight wall, guarantee that the plastic produced is consistent with the shape of design.
Description
Technical field
The utility model relates to plastic field more particularly to a kind of plastic straightening structures.
Background technique
Plastic is common component in industrial production, and injection molding is a kind of common plastic parts moulding production technology, it is
A kind of forming method of the simultaneous molding of injection, specially at a certain temperature, the plastic material melted completely by helical screw agitator is used
High pressure injects die cavity, after cooling and solidifying, the method that obtains molded product.The batch that this method is suitable for complex-shaped component is raw
It produces, is important one of processing method.The advantages of injection molding forming method is that speed of production is fast, high-efficient, and operating can be achieved automatically
Change, designs and varieties are more, and shape can go from the simple to the complex, and size can be descending, and product size is accurate, and product, which easily updates, to be changed
Generation, the product of energy forming shape complexity, injection molding are suitable for the processing and formings such as mass production and complex-shaped product field.At present
A kind of plastic by injection molding process, just the structure after machine-shaping is as shown in Fig. 1, including pedestal and be arranged the bottom of at
Thin-walled mount structure on seat, thin-walled mount structure are surrounded by the long vertical wall section of front, the short curved wall of two sides and subsequent long curved wall,
The shape is consistent with the shape of design, however there are biggish thermal stress in long vertical wall section after injection molding processing, behind answer
Long vertical wall section, which can deform, after power release concaves, and shape is as shown in Fig. 2, leads to the plastic produced and the shape of design not
Unanimously.
Utility model content
The utility model aim is exactly to provide a kind of plastic straightening knot to make up defect of the existing technology
Structure can correct plastic deformation formed after injection molding, keep the plastic produced consistent with the shape of design.
Technical solutions of the utility model are as follows: a kind of plastic straightening structure, including pedestal and are set on the base
Thin-walled mount structure, thin-walled mount structure are surrounded by the wall portion of front, the short curved wall portion of two sides and subsequent long curved wall portion,
It is characterized by: the shape of the wall portion of injection molding after processing is completed is the arc of convex.
Further, the shape of the arc of the convex is set, so that the shape of wall portion becomes straight after plastic deformation
Wall.
Further, the pedestal is provided with multiple jacks in the thin-walled mount structure.
Further, the jack includes a variety of various sizes of jacks.
Further, the plastic is automobile rubber shell connector.
Further, the plastic is about median plane bilateral symmetry.
Further, the pedestal of the plastic is rectangle structure, the wall portion of the front and subsequent long curved wall portion
Point parallel with the long side of the rectangle structure, the short curved wall portion of the two sides is parallel with the short side of the rectangle structure.
Further, the wall thickness phase of the wall portion of the front, the short curved wall portion of two sides and subsequent long curved wall portion
Together.
The utility model has the beneficial effects that: the shape by the wall portion by injection molding after processing is completed designs
For the arc of convex, the deformed shape of wall portion can be corrected, guarantees that the plastic produced is consistent with the shape of design.
Detailed description of the invention
Fig. 1 is the shape before the deformation of existing plastic.
Fig. 2 is the deformed shape of existing plastic.
Fig. 3 is the shape before the plastic deformation of the utility model.
Fig. 4 is the deformed shape of plastic of the utility model.
Wherein；1- pedestal；Wall portion before 2-；The short curved wall portion of the two sides 3-；The subsequent long curved wall portion of 4-.
Specific embodiment
Brief description is made to specific embodiment of the present utility model with reference to the accompanying drawing.
As shown in Figure 3-4, a kind of plastic straightening structure, plastic can be but be not limited to automobile rubber shell connector, wrap
The thin-walled mount structure for including pedestal 1 and being set on the base, thin-walled mount structure is by the wall portion 2 of front, the short curved wall portion of two sides
Points 3 and subsequent long curved wall portion 4 surround, the pedestal 1 is provided with multiple and different size jacks in the thin-walled mount structure,
The plastic is rectangle structure, 2 He of wall portion of the front about median plane bilateral symmetry, the pedestal 1 of the plastic
Subsequent long curved wall portion 4 is parallel with the long side of the rectangle structure, the short curved wall portion 3 of the two sides and the rectangle
The short side of structure is parallel, the wall thickness of the wall portion 2 of the front, the short curved wall portion 3 of two sides and subsequent long curved wall portion 4
Identical, the shape of the wall portion 2 of injection molding after processing is completed is the arc of convex.According to experimental setup to
The shape of the arc of evagination, so that the shape of wall portion 2 becomes straight wall after plastic deformation.The utility model will be by that will be molded into
The shape of the wall portion of type after processing is completed is designed as the arc of convex, and the thermal stress that plastic generates in process is released
It concaves after putting, so that the shape of deformed wall portion becomes straight wall, guarantees the plastic produced and design
Shape is consistent.
The utility model is not limited to above-mentioned specific embodiment, and various modifications and changes may be made to the present invention.
All foundation the technical essence of the utility model, should all to embodiment of above any modification, equivalent replacement, improvement and so on
Included in the protection scope of the utility model.
