Abstract
The invention discloses a kind of actuating arm die-casting processes.The following steps are included: 1., obtain need die casting actuating arm install taper hole relative dimensions；2., when production is calculated according to formula the installation taper hole of actual needs die casting inclined-plane relative to the angle between vertical plane, formula is
Description
Technical field
The present invention relates to wiper actuating arm technical field, especially a kind of actuating arm die-casting process.
Background technique
Vehicle wiper actuating arm is a component more important in automobile, for driving wiper to front windshield
It is cleaned, having guaranteed driver in the process of moving has the good visual field.
The mode that actuating arm generallys use die casting is produced, and is needed in whole production process while the good actuating arm of die casting
Installation taper hole, because installation taper hole has an inclined-plane, and there are shrinking percentages for material, are typically directly produced using standard size
Product, often had differences in final forming with standard size, therefore, the assurance for the angle on the inclined-plane is to examine drive
One test of swing arm total quality, currently, being merely able to adjust by way of subsequent repairing, influences the whole product of product
Matter.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of actuating arm die-casting process, by material before production
Material shrinking percentage is taken into account, and the relative dimensions and temperature that need when production are calculated by formula, to guarantee to actually obtain
The size of product reach standard size, without additional repairing, to promote the overall quality of product.
In order to solve the above technical problems, the present invention is addressed by following technical proposals: a kind of actuating arm die-casting process,
The following steps are included:
1., obtain need die casting actuating arm install taper hole relative dimensions, including installation taper hole upper end wall thickness δ 1, installation
Taper hole lower end wall thickness δ 2 and installation taper hole height H；
2., when production is calculated according to formula the installation taper hole of actual needs die casting inclined-plane relative between vertical plane
Angle, θ, formula isWherein T is temperature difference coefficient；
3., choose correspondingly-sized die casting, and die casting surface spray one layer of release agent；
4., molding；
5., injection；
6., die sinking；
7., ejection blank；
8., die casting post-processing, including blank conveying, blank cleaning, primary product machining and finished product final inspection.
In above scheme, it is preferred that step 5. in, shooting time range be 9-10s.
In above scheme, it is preferred that step 6. in, open time range be 6-7s.
In above scheme, it is preferred that step 7. in, ejection blank delay time be 1s.
The beneficial effects of the present invention are: the present invention takes into account material shrinkage before production, calculated by formula
It obtains the relative dimensions and temperature needed when production, to guarantee that the size of the product actually obtained reaches standard size, is not necessarily to
Additional repairing, to promote the overall quality of product.
Specific embodiment
Present invention is further described in detail With reference to embodiment: a kind of actuating arm die-casting process, including
Following steps:
1., obtain need die casting actuating arm install taper hole relative dimensions, including installation taper hole upper end wall thickness δ 1, installation
Taper hole lower end wall thickness δ 2 and installation taper hole height H.
2., when production is calculated according to formula the installation taper hole of actual needs die casting inclined-plane relative between vertical plane
Angle, θ, formula isWherein T is temperature difference coefficient, and temperature difference coefficient formulas isWherein, T1 is actual mold temperature, and T2 is actual device temperature, and T3 is standard module temperature, and T4 is mark
Quasi- device temperature.
3., choose correspondingly-sized die casting, and die casting surface spray one layer of release agent.
4., molding.
5., injection, wherein shooting time range be 9-10s.
6., die sinking, wherein open time range be 6-7s.
7., ejection blank, wherein ejection blank delay time be 1s.
8., die casting post-processing, including blank conveying, blank cleaning, primary product machining and finished product final inspection.
Different product refers to following table:
| δ1 | δ2 | σ | |
| H1 | 3.5 | 4.5 | 0.55% |
| H2 | 4 | 5 | 0.58% |
| H3 | 5 | 6 | 0.6% |
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
