Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Specifically, referring to fig. 1, the framework monomer 13 is 16 small framework monomers 13 and one large framework monomer 10, which are independent, in the process of injection molding, in the conventional process, each framework monomer 13 needs to be provided with a sprue, the framework mold is a cold runner mold, 17 sprues need to be provided with 17 runners, 17 runners are very expensive in material consumption in the process of injection molding, secondary injection molding is performed on the dispersed framework structure by using a two-color injection molding machine, after the framework is subjected to injection molding in a mold cavity, equipment rotates, and the framework is rotated to a soft rubber injection molding station for encapsulation injection molding.
Referring to fig. 2, the novel automobile storage box roller shutter door body of the invention comprises a hard rubber frame layer and a soft rubber wrapping layer, wherein the hard rubber frame layer comprises a plurality of frame monomers and hard rubber layers, the frame monomers are arranged in parallel at intervals, two ends of each frame monomer extend outwards to form heads, the hard rubber layers are wrapped on the surfaces of the frame monomers, the heads of adjacent frame monomers form a connecting body through the hard rubber layers, the soft rubber wrapping layer is wrapped on the surface of the hard rubber frame layer, and the hard rubber layers between the heads of the adjacent frame monomers are removed after the soft rubber wrapping layer is wrapped on the surface of the hard rubber frame layer.
Preferably on the basis of the scheme, the ebonite skeleton layer is an injection molding body, the injection molding body is formed in the ebonite cavity, the ebonite cavity is formed by combining an upper mold and a lower mold, a plurality of main body parts arranged in parallel at intervals and end parts connected with the main body parts are arranged on the upper mold and the lower mold, a communicated molding channel is arranged between the adjacent end parts, a cavity matched with the skeleton monomer is formed after the main body parts on the upper mold and the lower mold are spliced, a cavity matched with the head part is formed after the head part of the upper mold and the head part of the lower mold are spliced, and adjacent cavities form a mutually communicated structure under the action of the molding channel.
According to the invention, 17 dispersed framework monomers 13 are connected at two ends through the forming channels, the framework monomers 13 form a part after injection molding, and the injection molding only needs one sprue, so that compared with the structure shown in figure 1, 16 sprue and sub-runners are reduced in the part, and the material consumption is saved; the part is convenient to store after being molded, one part is a unit, and if the part structure in the prior art needs to be stored after being molded by injection alone, 17 scattered frameworks need to be stored together, so that the packaging difficulty is increased, the packaging quantity is reduced, and the packaging cost is directly increased.
The invention also provides a method for preparing the novel automobile storage box roller shutter door body, which comprises the following steps,
step S1, installing the skeleton monomer in the hard rubber cavity, connecting the hard rubber cavity into a whole by using a forming channel, and injecting glue for forming by an injection molding machine;
