Problems solved by technology
[0002] In the prior art, the color masterbatch flow marks on the surface of the product during injection molding seriously affect the appearance of the product
In the past, the injection process was adjusted and improved, but it was necessary to slow down the injection speed and prolong the product molding cycle. At present, the above situation has not been improved from the product design structure, so that there is no need to adjust the injection process to ensure the output rate and save manufacturing costs.

Embodiment
[0020] An injection molded product that can improve the flow marks of color masterbatch, its structure is as follows Figure 2-3 As shown, the top of the injection molded product is provided with a filling point 1, and the inner top surface of the injection molded product is provided with an arc-shaped reinforcing rib 4. The arc-shaped reinforcing ribs 4 are evenly arranged on the inner top surface of the injection molded product, diverging from the center to the outside. The direction in which the arc-shaped reinforcing rib 4 is set is the same as the shearing direction of the screw shot of the injection molding machine.
[0021] In the present invention, the linear reinforcing rib 2 is changed into an arc-shaped reinforcing rib 4, which slows down the resin injection speed, and the arc-shaped flow direction reduces the impact on the side wall 3 of the product when the resin is injected. The direction is the same, so that the resin is injected into the mold from the injectio...

The invention relates to an injection molding product capable of improving color master flow marks. The top of the injection molding product is provided with a pouring point; the inner top surface of the injection molding product is provided with arc-shaped reinforcing ribs; the reinforcing ribs are uniformly arranged on the inner top surface of the injection molding product, and are scattered from the center to outside; the arrangement direction of the reinforcing ribs is the same with the shearing direction of screw rod ejection materials of an injection molding machine. Compared with the prior art, the injection molding product capable of improving color master flow marks provided by the invention does not influence the product outer appearance structure, is only changed subtly in the internal part, keeps the original appearance design of the product, can improve the production efficiency, and save the production cost.
Description
technical field [0001] The invention relates to an injection molded product, in particular to an injection molded product which can improve flow marks of color masterbatch. Background technique [0002] In the prior art, the color masterbatch flow mark produced on the surface of the product during injection molding seriously affects the appearance of the product. In the past, the injection process was adjusted and improved, but it was necessary to slow down the injection speed and prolong the product molding cycle. At present, the above situation has not been improved from the product design structure, so that there is no need to adjust the injection process to ensure the output rate and save manufacturing costs. Contents of the invention [0003] The object of the present invention is to provide a fine-tuned structure to overcome the defects of the above-mentioned prior art, thereby improving production efficiency and saving production costs, and can improve the flow mark...
