Abstract
The invention relates to a sealed structure for a gas aided injection molding technological hole of an automobile door handle. The sealed structure comprises a door handle, and is characterized by further comprising a blocking cover used for blocking the gas aided injection molding technological hole, wherein the gas aided injection molding technological hole is formed in the door handle; the blocking cover comprises a main body part and a cap part which are integrally arranged; the main body part is used for being plugged into the gas aided injection molding technological hole; the outer diameter of the cap part is greater than the opening diameter of the gas aided injection molding technological hole; a circle of blocking cover welding wire capable of fusing under the ultrasonic high-frequency vibration is arranged on the peripheral edge of the lower surface of the cap part; the blocking cover is buckled on the hole edge of the gas aided injection molding technological hole; the blocking cover welding wire is fused under the ultrasonic high-frequency vibration to weld the blocking cover with the door handle. According to the invention, the structure is simple, the operation is convenient, the gas aided injection molding technological hole of the automobile door handle can be kept sealed during the electroplating process, the electroplating quality is ensured, and the yield of the handle electroplating is improved; the electroplate liquid cross contamination accident is avoided, and the loss of the electroplating factory is reduced.
Description
Technical field
The present invention relates to the sealing configuration of gas-assisted injection molding auxiliary hole on automobile door handle, belong to automobile assembling technical field.
Background technique
Along with expanding economy, automobile has become the traffic tool that people commonly use, and the market demand of automobile constantly increases, and client requires more and more higher to each side of automobile, automobile door handle serviceability and aesthetic property also obtain paying close attention to of client.
In order to ensure the intensity of automobile handle, simultaneously in order to control the manufacturing cost of automobile door handle, usually adopt now gas-assisted injection molding technique vaginal orifice in the next life handle of a kind of advanced person, it can solve strength problem and the materials Cost Problems of automobile door handle simultaneously.In order to make the outward appearance of automobile door handle more attractive in appearance, we are at electroplating surface one deck light chromium of automobile door handle, because gas-assisted injection molding technique can leave a gas-assisted injection molding auxiliary hole 1a(as shown in Figure 1 on automobile door handle 1), this hole needs firmly to block in electroplating process.Rubber stopper 4 is usually adopted now to carry out shutoff gas-assisted injection molding auxiliary hole 1a(as shown in Figure 2), but there is following shortcoming in this shutoff mode: because have difference variation in electroplating process, rubber stopper expands with heat and contract with cold, plugging effect is very poor, easily make hollow door handle die cavity can pour into electroplating chemical liquid medicine, and can overflow at other follow-up plating stage, after liquid medicine overflows, first can flow to the surface of door handle, define not purgeable stain, plating leakage, etc. bad; Secondly the liquid medicine of different cylinder body can be caused to mix, occur cross pollution accident, pollute to electroplating pool, cause liquid medicine to cancel, cause extreme loss.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the sealing configuration of gas-assisted injection molding auxiliary hole on a kind of automobile door handle is provided, its structure is simple, easy to operate, can ensure that on automobile door handle, gas-assisted injection molding auxiliary hole keeps sealing in electroplating process, ensure electroplating quality, avoid occurring cross pollution accident, greatly reduce cost of production.
According to technological scheme provided by the invention: the sealing configuration of gas-assisted injection molding auxiliary hole on automobile door handle, comprise door handle, by gas-assisted injection molding auxiliary hole on described door handle, it is characterized in that: also comprise the blanking cover for gas-assisted injection molding auxiliary hole described in shutoff, described blanking cover comprises the main part and cap portion that are wholely set, described main part is used for filling in gas-assisted injection molding auxiliary hole, the external diameter of described cap portion is greater than the aperture of gas-assisted injection molding auxiliary hole, lower surface week of cap portion can the blanking cover bonding wire of melting under ultrasound high-frequency vibration along being provided with a circle, described blanking cover is buckled in the hole of gas-assisted injection molding auxiliary hole along upper, blanking cover bonding wire becomes molten state under ultrasound dither, blanking cover and door handle are welded together.
As a further improvement on the present invention, the main part of described blanking cover and gas-assisted injection molding auxiliary hole are interference fit.
As a further improvement on the present invention, described blanking cover adopts the material identical with door handle to make.
compared with prior art, tool has the following advantages in the present invention:structure of the present invention is simple, easy to operate, can ensure that on automobile door handle, gas-assisted injection molding auxiliary hole keeps sealing in electroplating process, ensures electroplating quality, improve the yield of handle plating; Avoid occurring electroplate liquid cross pollution accident, greatly reduce cost of production, decrease the loss of plating producer.

Fig. 1 is the door handle structure schematic diagram adopting gas-assisted injection molding explained hereafter.
Fig. 2 is the sealed structural representation that in Fig. 1, door handle adopts rubber stopper seal gas-assisted injection molding auxiliary hole.
Fig. 3 is the blockage structure schematic diagram of the embodiment of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, Figure 3, on the automobile door handle in embodiment, the sealing configuration of gas-assisted injection molding auxiliary hole forms primarily of door handle 1 and blanking cover 2, and by gas-assisted injection molding auxiliary hole 1a on described door handle 1, described blanking cover 2 is for shutoff gas-assisted injection molding auxiliary hole 1a; Described blanking cover 2 comprises the main part 2a and cap portion 2b that are wholely set, described main part 2a is used for filling in gas-assisted injection molding auxiliary hole 1a, the external diameter of described cap portion 2b is greater than the aperture of gas-assisted injection molding auxiliary hole 1a, lower surface week of cap portion 2b can blanking cover 2 bonding wire 3 of melting under ultrasound high-frequency vibration along being provided with a circle, described blanking cover 2 is buckled in the hole of gas-assisted injection molding auxiliary hole 1a along upper, blanking cover 2 bonding wire 3 becomes molten state under ultrasound dither, blanking cover 2 and door handle 1 is welded together.
In the embodiment of the present invention, described blanking cover 2 preferably adopts the material identical with door handle 1 to make, and main part 2a and the gas-assisted injection molding auxiliary hole 1a of blanking cover 2 are preferably interference fit.
During concrete use, use ultrasonic welding, first the main part 2a of blanking cover 2 is inserted in the gas-assisted injection molding auxiliary hole 1a on door handle 1, be placed on special tooling; Then the cap portion 2b of blanking cover 2 is pushed down with ultrasound upper die head, ultrasound machine sends high-frequency vibration, blanking cover 2 bonding wire 3 is made to produce high heat and become molten state, then blanking cover 2 is compressed, after cooling, blanking cover 2 just welds together very securely with door handle 1, and such gas-assisted injection molding auxiliary hole 1a is just blocked firmly.
