Detailed Description

The invention is further described with reference to the drawings and the detailed description.

As shown in fig. 1, 2 and 3: injection molding pad pasting tool, including base 1, fixed mounting has a plurality of bracing pieces 2 on the base 1, and in this embodiment, the quantity of bracing piece 2 is two, and is located base 1's both ends respectively, and the common fixed mounting in top of a plurality of bracing pieces 2 has lower bolster 3, and the effect of bracing piece 2 is to supporting lower bolster 3 to make lower bolster 3 keep on the horizontal plane. The top surface of the lower template 3 is provided with a plurality of placing grooves 31 and a plurality of positioning holes 32, in the embodiment, the placing grooves 31 are arranged along the axial direction of the lower template 3, and because each placing groove 31 is provided with an injection molding part, a plurality of injection molding parts can be subjected to film pasting at one time, so that the working efficiency is greatly improved; further set up through 31 axial arrangements of a plurality of standing grooves and make a plurality of injection molding interval arrangements on lower die plate 3 for a plurality of injection molding interval arrangements's pressfitting is between two protection films, when the user tailors the injection molding of corresponding quantity according to the use needs, not fragile adjacent injection molding, thereby realized convenient to use's technological effect. The positioning holes 32 are located on the outer sides of the plurality of placing grooves 31, and since holes with the same size and corresponding to the positioning holes 32 are formed in the edge of the protective film placed on the positioning pins 52 of the upper die plate 5, the positioning holes 32 are arranged on the outer sides of the placing grooves 31, so that a plurality of injection molded parts fall within the coverage range of the protective film. A plurality of cylinders 4 of bottom fixed mounting of lower bolster 3, lower bolster 3 is worn out respectively to the push rod of every cylinder 4, and at the common fixed mounting of tip have with the cope match-plate pattern 5 that lower bolster 3 parallels, cylinder 4 is used for transmission cope match-plate pattern 5 to carry out pressfitting or separation to lower bolster 3, utilize cylinder 4 to make the protection film of placing on cope match-plate pattern 5 and place a plurality of injection moldings on lower bolster 3 carry out the pressfitting, the realization is to a plurality of automatic pad pasting's of moulding plastics technological effect, thereby workman's intensity of labour has been alleviateed effectively, and the work efficiency is improved, the pad pasting cost is reduced. The bottom surface of the upper template 5 is provided with a plurality of clamping grooves 51 corresponding to the placing grooves 31 and a plurality of positioning pins 52 matched with the positioning holes 32, and the positioning pins 52 are used for placing a protective film, so that the position of the injection molding part adhered on the protective film corresponds to the position of the clamping grooves 51, and the film sticking quality of the injection molding part is further ensured. The clamping groove 51 and the placing groove 31 are the same in size, and the clamping groove 51 and the placing groove 31 are matched with the surface of the injection molding piece.

The working principle is as follows: the air cylinder 4 drives the upper template 5 to move upwards, so that the upper template 5 is separated from the lower template 3, a plurality of injection molded parts are sequentially placed in the placing groove 31 of the lower template 3, and each injection molded part is enabled to face upwards in a sticky mode; meanwhile, a protective film with one side having adhesiveness is placed on the positioning pin 52 of the upper template 5 to be positioned, and the side having adhesiveness of the protective film faces downward; after the placing step is completed, the push rod of the cylinder 4 is reset, so that the upper template 5 and the lower template 3 are pressed, the protective film with the sticky surface and the multiple injection molding parts with the sticky surfaces are pressed into a whole, then the cylinder 4 drives the upper template 5 to move upwards, so that the upper template 5 drives the protective film on the positioning pin 52 and the multiple injection molding parts which are bonded with the protective film in a pressing way to move upwards, another protective film without the sticky surface and with the same shape and size as the protective film with the sticky surface is placed on the positioning pin 52 of the upper template 5 to be positioned and covered below the multiple injection molding parts, after the placing step is completed, the push rod of the cylinder 4 is reset, so that the upper template 5 and the lower template 3 are pressed, so that the multiple injection molding parts are packaged between the protective film with the sticky surface and the protective film without the sticky surface, and the cylinder 4 drives the upper template 5 to move upwards, the injection molded part with the film adhered to the positioning pin 52 is taken down, and finally, the push rod of the cylinder 4 is reset.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
