Abstract
The invention discloses a lightweight secondary injection molding sealing structure. The lightweight secondary injection molding sealing structure comprises a clad body and a cladding body, wherein one or more than one sealing sharp edge is arranged between the clad body and the cladding body, the sealing sharp edge is made of polyethylene; when the clad body and the cladding body are subjected to injection molding secondarily and heat is transferred to the sealing sharp edge, the sealing sharp edge absorbs heat and is molten to form a mixed body together with the clad body and the cladding body. When the clad body and the cladding body of the secondary injection molding part are designed, one or more sealing sharp edges are arranged on the clad body, the heat of the cladding body is transferred to the sealing sharp edge of the clad body during secondary injection molding, the sealing sharp edge is molten since heat cannot be rapidly transferred due to the structure reason, so that the clad body and the cladding body form the mixed body to achieve the high-pressure resistant sealing effect.
Description
Technical field
The present invention relates to quadric injection mould Sealing Technology, particularly a kind of lightweight quadric injection mould hermetically-sealed construction.
Background technology
Quadric injection mould can increase product functionality and added value can not be again that cost increase is too many.In past 10 years, quadric injection mould technology is thorough changes product aesthetical standard, mentality of designing and functional requirement.Auto parts and components manufacturer also recognizes the potential advantages of this technology, constantly expands its application in auto parts and components field.Quadric injection mould technology with create " soft feeling surface and well-known, but it also have other functions many, such as: ergonomic designs, double-colored outward appearance, brand identity and improved properties.Utilize this technology can increase energy (such as: noise abatement, damping, waterproof, crashproof) and the added value of product.But also there is sealing problem in quadric injection mould in the application of auto parts and components field, be applied in without the need on sealing or the parts of low pressure seal at present mostly, the parts needing high pressure sealing still use traditional seal seal form, so both can increase pts wt, cost also can increase manufacturing technique requirent.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides one and being applicable to require damping, shock-resistant, warping strength, sealing and elasticity, oil resistant, chemicals-resistant and require the lightweight quadric injection mould hermetically-sealed construction of sufficient intensity.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of lightweight quadric injection mould hermetically-sealed construction, it is characterized in that: comprise and be wrapped by body and cladding, described being wrapped by between body and cladding is provided with one or more than one sealing sharp edge, described sealing sharp edge is that the easy molten plastic of high temperature is made, described sealing sharp edge is when being wrapped by body and cladding quadric injection mould, temperature is sealed sharp edge when being passed to sealing sharp edge and is absorbed fusing, and is wrapped by body and cladding forms mixture.
As a further improvement on the present invention, described sealing sharp edge is polyethylene
The invention has the beneficial effects as follows: the present invention is when designing secondary injection plastic and being wrapped by body and cladding, be wrapped by design one or many sealing sharp edges on body. utilizing the temperature conduction of the cladding when carrying out quadric injection mould to it causes temperature cannot transmit the principle of fuse itself fast because of reasons in structure when being wrapped by body sealing sharp edge, making itself and cladding form mixture and having reached high-pressure-resistant sealed effect.
The technique of low cost lightweight quadric injection mould Sealing Technology quadric injection mould of the present invention more can be widely used in auto-parts and manufacture the cost decline 20% that field can also be parts; improving productivity 52%. decreases the use of rubber type of material, thus better emissions reduction protects natural environment.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present invention;
Fig. 2 is one of structural representation of the present invention;
Indicate in figure: 1-is wrapped by body; 2-cladding; 3-seals sharp edge.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of embodiment of a kind of lightweight of the present invention quadric injection mould hermetically-sealed construction, comprise and be wrapped by body 1 and cladding 2, described being wrapped by between body 1 and cladding 2 is provided with one or more than one sealing sharp edge 3, described sealing sharp edge 3 is made for the easy molten plastic of high temperature, described sealing sharp edge 3 is when being wrapped by body 1 and cladding 2 quadric injection mould, temperature is sealed sharp edge when being passed to sealing sharp edge and is absorbed fusing, and is wrapped by body 1 and cladding 2 forms mixture.Described sealing sharp edge 3 is polyethylene
.when carrying out quadric injection mould, the temperature conduction of cladding is to when being wrapped by body sealing sharp edge, it causes temperature cannot transmit the principle of fuse itself fast because of reasons in structure, makes itself and cladding form mixture and has reached high-pressure-resistant sealed effect.
