Abstract
The utility model relates to the technical field of automobile parts and accessories, and especially relates to a plastic component with no bubble surfaces on a glue feeding surface. The plastic component comprises a pouring gate, a plastic body area and a welding line area which are arranged in turn along a melt glue flowing direction, wherein thickness of the welding line area is smaller than that of the plastic body area, i.e., glue is reduced in the welding line area, such that flowing time of the melt glue is shortened, thereby effectively preventing bubble surfaces caused by cooling of melt glue passages at positions close to the welding line area from occurring. The plastic component provided by the utility model has the advantages of being simple in structure and high in product yield.
Description
Technical field
The utility model relates to automobile and joins the component technology field, particularly a kind of plastic parts that enters still of glue surface.
Background technology
Joint line (welding line) also be weld bond, be exactly plastic cement products in injection moulding process, melten gel has the melten gel fluid of two strands or multiply to converge formed line after cast gate injects in certain position of mould.
Existing vehicular spare parts mostly is plastic cement products, and such as the gear of automobile frame, car door panel etc., they are critical function spare and ornamental trimming on the automobile.During injection molding, area such as fruit product in advancing the process of glue is larger, the colloidal sol runner is longer, the time of colloidal sol circulation will be more of a specified duration, therefore the colloidal sol of circulation can cool off gradually, finally causes producing the bubble face on the surface of joint line position, i.e. the cokled surface of plastic cement products and the inner phenomenon that hollow is arranged, directly affect product appearance, product quality is low.
In the prior art, usually advance glue laminated power and firing rate by the forming machine adjustment, avoid the generation of the face that steeps.Yet excessive when firing rate, pressure strengthens, and the temperature of colloidal sol will rise, and causes the position of joint line to burn, and is out of condition; Too small when firing rate, pressure reduces, and can not solve the problem of bubble face, and product quality is low.
Summary of the invention
The purpose of this utility model is that a kind of plastic parts that enters still of glue surface is provided for the deficiencies in the prior art, and it can effectively avoid product surface to produce the bubble face, and is simple in structure and product quality is high.
For achieving the above object, the utility model adopts following technical proposals.
A kind of plastic parts that enters still of glue surface, described plastic parts comprise cast gate, plastic body zone and the joint line zone that sets gradually along the colloidal sol flow direction, and the thickness in described joint line zone is less than the thickness in described plastic body zone.
Wherein, the thickness in described joint line zone is the 1/3-2/3 of the thickness in described plastic body zone.
Wherein, the thickness in described joint line zone be described plastic body zone thickness 1/2.
Wherein, the back side in described joint line zone is curved.
Wherein, the thickness of the joint line position in described joint line zone is minimum.
Wherein, the outer ledge in described joint line zone is provided with reinforced rib, and reinforced rib and the setting of described joint line regions perpendicular.
Above, described plastic parts is provided with some strengthening ribs.
Wherein, described some strengthening ribs and described plastic parts are one-body molded.
The utility model beneficial effect is: the thickness in joint line of the present utility model zone is less than the thickness in plastic body zone, namely subtract glue in the position in joint line zone, so just can shorten the currency of colloidal sol, thereby prevent that effectively the colloidal sol runner from producing the bubble face in the position near the joint line zone owing to cooling causes product surface, the utlity model has advantage simple in structure and that product quality is high.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not consist of any restriction of the present utility model.
Fig. 1 is a kind of structural representation that advances the plastic parts on still of glue surface of the utility model.
In Fig. 1, include:
10---the plastic body zone
11---the joint line zone
12---cast gate
13---strengthening rib.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of plastic parts that enters still of glue surface of the present utility model, described plastic parts comprises cast gate 12, plastic body zone 10 and the joint line zone 11 that sets gradually along the colloidal sol flow direction, and the thickness in described joint line zone 11 is less than the thickness in described plastic body zone 10.
When injection molding, melten gel is from cast gate 12 to flowing all around, the thickness in joint line zone 11 is less than the thickness in plastic body zone 10, then the position of the thickness of product from plastic parts body regions 10 to joint line zone 11 reduces gradually, namely subtract glue in the position in joint line zone 11, so just can shorten the currency of colloidal sol, thereby prevent that effectively the colloidal sol runner from producing the bubble face in the position near joint line zone 11 owing to cooling causes product surface, the utlity model has advantage simple in structure and that product quality is high.
The thickness in the joint line zone 11 of present embodiment is the 1/3-2/3 of the thickness in described plastic body zone 10.Preferably, the thickness in joint line zone 11 be described plastic body zone 10 thickness 1/2, the thickness in joint line zone 11 is of moderate size, and on the one hand is conducive to prevent that product surface from producing the bubble face phenomenon, product quality is high; Be conducive on the other hand improve the structural strength in joint line zone 11, improve reliability of service of the present utility model.
The back side in the joint line zone 11 of present embodiment is curved, simple in structure, is convenient to machine-shaping, is conducive to realize subtracting glue in joint line zone 11, thereby avoids product surface to produce the bubble face.
The thickness of the joint line position in the joint line zone 11 of present embodiment is minimum, and the thickness of joint line position is minimum, and it is minimum that then the colloidal sol of joint line position advances the glue amount, effectively avoids producing the bubble face phenomenon in the joint line position, and product quality is high.
The outer ledge in the joint line zone 11 of present embodiment is provided with reinforced rib, and reinforced rib and the 11 vertical settings of described joint line zone.Outer ledge in joint line zone 11 arranges reinforced rib, make reinforced rib and joint line orthogonal, effectively disperseed the focal point of stress on the joint line, improved the structural strength in joint line zone 11, effectively avoid plastic parts to deform in joint line zone 11 even rupture, improved reliability of service of the present utility model.
The plastic parts of present embodiment is provided with some strengthening ribs 13, has further improved structural strength of the present utility model.Wherein, described some strengthening ribs 13 are one-body molded with described plastic parts, reduced production and processing operation of the present utility model, improve work efficiency, reduce production costs.
Certainly, the above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
