[0002] In the injection molding process of multi-color joints, flow marks often appear on the surface of metallic parts after injection molding, which affects the appearance. In order to eliminate the appearance defects caused by flow marks, other post-processing processes such as masking spraying are usually used to cover the metallic flow marks on the surface of the parts, thereby achieving a smooth and traceless effect on the outside of the parts. However, spraying after the parts are injection molded not only increases the processing cost, but also prolongs the processing time of the parts and reduces the processing efficiency of the parts.

[0036] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0037] Embodiment 1:

[0038] The present invention provides a building block structure, comprising a building block 1, wherein the wall thickness of the building block 1 after injection molding is all controlled within the range of 0.8 to 2 mm. By controlling the overall wall thickness of the building block 1 within the range of 0.8 to 2 mm, the metallic flow marks on the outer surface of the building block 1 after injection molding disappear, thereby greatly improving the aesthetic appearance of the building block 1.

[0039] In practical applications, the wall thickness of the building block 1 can be 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc., preferably 1.5mm.

[0040] The present invention also provides a method for molding a building block structure, so that the wall thickness of the building block pieces 1 after injection molding is completely controlled within the range of 0.8 to 2 mm.

[0041] Specifically, the building block 1 has an inner cavity, and the inner cavity and the outer surface of the building block 1 form a wall thickness. The inner cavity has an opening, and the inner cavity is connected to the outside through the opening. In practical applications, the inner cavity can realize the function of the splicing hole 11. The building block 1 is preferably a cylindrical structure. By controlling the wall thickness of the building block 1, the influence of the flow marks on the outer appearance of the building block 1 on the appearance of the parts is eliminated, and the appearance of the parts is improved. Figure 2 shown.

[0042] The present invention also provides a joint, including a building block structure, the joint adopts the building block structure of the present invention, and the joint is a multi-color joint, such as Figure 5 , Figure 6 As shown, the manufacturing process can be simplified, the processing efficiency can be improved, and the production cost can be reduced.

[0043] The invention also provides a toy, comprising a building block structure.

[0044] Embodiment 2:

[0045] This embodiment provides a building block structure, including a building block 1. Different from the first embodiment, the wall thickness of the building block 1 after injection molding is controlled within the range of 0.8 to 2 mm.

[0046] When the overall thickness of the building block 1 is within the range of 2.2 to 3 mm, the flow marks on the outside of the building block 1 are relatively serious. To solve the above problem, in this embodiment, the mouth portion is provided with a notch 111 extending radially outward. The wall thickness L corresponding to the notch 111 of the building block 1 is 1.97 mm. Figure 1 As shown, the cross-section of the notch 111 is preferably a cut circle or an arc, the injection port 2 of the injection molded building block 1 is opposite to the notch 111, and the notch 111 extends from the mouth of the building block 1 to the bottom of the inner cavity. In this embodiment, the wall thickness at the notch 111 is controlled to eliminate the metallic flow marks on the outer surface of the building block 1, thereby greatly improving the aesthetics of the outer surface of the part.

[0047] It should be noted that the thickness L of the building block 1 corresponding to the notch 111 is preferably 0.8-1.5 mm, for example, L is 1 mm, 1.2 mm, etc.

[0048] In this embodiment, the wider the width of the notch 111, the better the effect of eliminating the flow marks on the outer surface of the building block 1. However, if the notch 111 is too wide, it will affect the function of the splicing hole 11 and reduce the firmness of the building block spliced ​​into the splicing hole 11. In order to ensure the splicing function of the splicing hole 11 and eliminate the flow marks on the outer surface of the building block 1, the maximum width M of the notch 111 should be within the range of 1 to 2.5 mm, such as 1.5 mm, 1.8 mm, 2 mm, etc. By controlling the width of the notch 111, the glue reduction function can also be achieved inside the injection molded building block 1, so that the wall thickness of the part of the building block 1 (the thickness L of the building block 1 corresponding to the notch 111) meets the range of 0.8 to 2 mm, preferably L is 0.8 to 1.5 mm, which is conducive to eliminating the metallic color flow marks on the outer surface of the building block 1. At the same time, the glue inlet 2 of the injection molded building block 1 is directly opposite to the notch 111, which is also conducive to the beauty of the outer surface of the building block 1.

[0049] Embodiment 3:

[0050] The present embodiment is different from the first embodiment in that the building block 1 is a plate-like structure, and the flow marks on the outer surface can be controlled by controlling the wall thickness of the plate-like building block 1, thereby achieving a smooth and beautiful exterior.

[0051] The plate-like structure in this embodiment can be a rectangular structure, an arc-shaped plate structure, a special-shaped plate, etc., and the flow marks on the outer surface after injection molding can be controlled by controlling the wall thickness, thereby improving the aesthetics of the parts.

[0052] Comparative Example:

[0053] like Figure 3 As shown, the wall thickness of the building block 1 is N, and the value of N is 2.53 mm. After injection molding, obvious flow marks appear on the outside of the building block 1, such as Figure 4 As shown, the aesthetic appearance of the part is greatly reduced.
