Description

Aluminum-plastic hot-pressing water-cooling circulating die

Technical Field

The utility model relates to the technical field of mold, in particular to aluminum-plastic hot pressing water-cooling circulation mould.

Background

Aluminum is used as a metal material, and is difficult to finish on a small volume, easy to deform and convenient without a plastic part; the injection molding of plastic parts is convenient in complex structure, but the strength is inferior to that of metal materials. The aluminum-plastic combined shell has the advantages of the two, and is adopted by more and more notebook computer shells.

A Hopper 12 LTE aluminum alloy back cover produced by our company has a deformation degree of a rotating shaft side exceeding SPECC 1.0mm after binding hot pressing a plastic support. This results in overall heating of the product because the heated area in the Bonding process is relatively large. The thermal residual stress causes deformation due to the inconsistency of the coefficient of linear expansion and the heat conduction of the aluminum and the plastic.

Therefore, it is necessary to design a new mold to reduce the cooling deformation of the aluminum-plastic bonded shell after heating.

Specifically, the clamping device comprises a clamping cylinder fixed on the lower template and a movable baffle driven by the clamping cylinder.

Furthermore, a sliding rail used for guiding the movable baffle plate to stretch along the direction of the main shaft of the clamping cylinder is arranged on the lower template.

Specifically, a plurality of stand columns are arranged on the lower template, and a plurality of guide sleeves matched with the stand columns are arranged on the upper template.

Specifically, a stripping device is further arranged below the lower template and comprises a plurality of stripping cylinders, and the stripping cylinders drive a jacking head used for jacking the aluminum-plastic combined part from the lower template.

Further, the stripping cylinder is driven by a pneumatic switch.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

the utility model discloses an go up the mould heating, lower mould refrigerated mode makes the plastic-aluminum conjunction just solidify with higher speed in the mould, and no deformation is unusual, and the quality is reliable.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses an aluminum-plastic hot pressing water-cooling circulation mould, including cope match-plate pattern 1 and lower bolster 2, be equipped with on the lower bolster 2 and be used for letting a plurality of quiet dogs 22 of aluminium part and the rough location of a mould and be used for letting the aluminium part with mould a tight clamping device 3 of side direction clamp, be equipped with the heating pipe (not drawn) in the cope match-plate pattern 1, be equipped with circulation water route 21 in the lower bolster 2. During operation, a plastic part is placed on the lower template 2 for positioning, then the aluminum part with glue dispensed is placed in a processing area surrounded by the static stop block 22 and is bonded by AB glue, the clamping device 3 is started to enable the aluminum part and the plastic part to be clamped laterally, poor connection caused by too large gaps is prevented, the temperature of the upper template 1 is maintained at 118-124 ℃ by heating of the heating pipe, the temperature of the lower template 2 is maintained at 18-22 ℃ by introducing cooling water into the circulating water path 21, then the upper template 1 is lowered to be matched with the lower template 2, the mold is opened after 90s of pressing, the clamping device 3 is loosened, and the aluminum-plastic combined part is taken out. Through repeated experiments, the standard that the deformation degree is less than 1.0mm after 3000pcs of back plate is combined in the production of aluminum plastic indicates that the improvement effect is stable. The utility model discloses an go up the mould heating, lower mould refrigerated mode makes the plastic-aluminum conjunction just solidify with higher speed in the mould, and no deformation is unusual, and the quality is reliable.

As shown in fig. 1 to 3, the clamping device 3 includes a clamping cylinder 31 fixed to the lower die plate 2 and a movable fence 32 driven by the clamping cylinder 31. During the use, move the baffle 32 and the cooperation of the quiet dog 22 of relative position on the lower bolster 2, let aluminium parts and mould the piece and be close to, make seam crossing reduce, just can accord with the standard with the combination condition between them after the pressfitting like this. The movable fence 32 may be driven by one clamp cylinder 31, or may be driven by a plurality of clamp cylinders 31 simultaneously.

As shown in fig. 1 and 2, the lower platen 2 is provided with a slide rail 23 for guiding the movable fence 32 to extend and contract along the main axis direction of the clamp cylinder 31. The slide rail 23 of the movable baffle 32 can reduce the abrasion of the main shaft of the clamping cylinder 31, and has a positive effect on prolonging the service life of the clamping cylinder. The slide rails 23 can be generally arranged in parallel 2-3.

As shown in fig. 1 and 2, the lower template 2 is provided with a plurality of columns 24, and the upper template 1 is provided with a plurality of guide sleeves 11 matching with the columns 24. The matching of the upright column 24 and the guide sleeve 11 can ensure that the die assembly positions of the upper template 1 and the lower template 2 are accurate.

As shown in fig. 1 to fig. 3, a stripping device 4 is further disposed below the lower mold plate 2, the stripping device 4 includes a plurality of stripping cylinders 41, and the stripping cylinders 41 drive a plug (not shown) for jacking the aluminum-plastic joint from the lower mold plate 2. Some notebook computers have a casing with edges, and the casing is easily wrapped on a lower die when the lower die is cooled, so that the casing needs to be ejected from the lower part by an ejector head to be successfully stripped.

As shown in fig. 2 and 3, the stripper cylinder 41 is actuated by a pneumatic switch 42. The pneumatic switch 42 can drive the plurality of stripping cylinders 41 to act simultaneously at one time, so that the problem caused by uneven stripping force of the aluminum-plastic combination part can be prevented.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
