Description

Technical Field

[0001] The present invention relates to the technical field of toys, and in particular to a toy structure, a molding method of the toy structure and a toy thereof. Background Art

[0002] Two-color building blocks are made with two-color molds. Two-color molds are molded with two plastic materials on the same injection molding machine, in two steps, but the product is only ejected once.

[0003] For the injection molding of two-color joint building blocks, injection molding is carried out in two times. After the first color joint parts are injection molded and solidified, the second color joint parts are injection molded and solidified. When the melt temperature of the first shot intersects with the melt temperature of the second shot, when the second color joint parts are injection molded after the first color joint parts are solidified, the temperature of the second color melt will cause melting points to appear at the glue-wrapped positions of the first color joint parts. The appearance of melting points will cause the solidified joint parts to rotate poorly or get stuck during the rotation process, affecting the quality of the product and greatly reducing the fun of the toy and the user experience. Summary of the invention

[0011] A toy structure provided by the present invention comprises a first resin part which is firstly injection-molded and a second resin part which is later injection-molded and can cooperate with the first resin part in a rotational form;

[0012] The second resin part has an assembly hole at a portion away from the first resin part, and the assembly hole has an extension portion at one end close to the first resin part.

[0039] 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.

[0040] Embodiment 1:

[0041] The present invention provides a toy structure, comprising a first resin part 1 and a second resin part 2. The first resin part 1 and the second resin part 2 are resin parts of different colors and are manufactured by sequential injection molding. Specifically, the toy structure is first injection-molded with a first resin part 1, and then with a second resin part 2, and the second resin part 2 can cooperate with the first resin part 1 in a rotating form, and the second resin part 2 has a rubber-coated part in contact with the first resin part 1. Since the melting temperature of the first resin part 1 is higher, the melting temperature of the second resin part 2 is lower, and the two melting temperatures intersect, the selection of the position of the injection point when injecting the second resin part 2 will cause the surface of the first resin part 1 to produce a melting phenomenon, and then cause the appearance of a melting point on the surface of the first resin part 1. In order to avoid the appearance of a melting point on the surface of the first resin part 1, when injecting the second resin part 2, the injection point is located on one side of the second resin part 2 and is selected at a position far away from the rubber-coated part. When the melt flows from the injection point to the rubber-coated part, the heat is partially dissipated, so the temperature will be reduced. The highest temperature when the melt of the second resin part 2 reaches the surface of the first resin part 1 is lower than the lowest temperature of the melt of the first resin part 1. The present invention sets the position of the injection point of the post-injection resin part so that the temperature of the melt of the post-injection resin part is slightly reduced when it contacts the surface of the first resin part 1, which will not cause the surface of the first resin part 1 to become molten, and will not cause the surface of the first resin part 1 to deform, thereby improving product quality.

[0042] It should be noted that when the melt temperature of the first resin part 1 to be injected is high, the melt temperature of the second resin part 2 is low, and there is no intersection between the melt temperatures of the first resin part 1 and the second resin part 2, the problem of selecting the position of the injection point can be ignored.

[0043] In the toy structure after injection molding in the present invention, the first resin part 1 and the second resin part 2 are of different colors, and the first resin part 1 and the second resin part 2 are non-detachable and structurally integrated, which can improve the overall splicing efficiency of the toy and increase the stability and interest of the toy.

[0044] The present invention also provides a molding method for a toy structure, which comprises the steps of first injection molding a first resin part 1, and then injection molding a second resin part 2, so that the first resin part 1 and the second resin part 2 are rotatably matched; the second resin part 2 has a rubber-coated part in contact with the first resin part 1, and a glue-in point is located on one side of the second resin part 2 when the second resin part 2 is injected. When the selection of the position of the glue-in point will cause a melting phenomenon on the surface of the first resin part 1, the position of the glue-in point is selected to be far away from the rubber-coated part, so that the temperature of the melt of the second resin part 2 injected into the mold reaches the surface of the first resin part 1 is lower than the lowest temperature of the melt of the first resin part 1 injected into the mold, so as to avoid the occurrence of a melting point on the surface of the first resin part 1 and affect the product quality.

[0045] Specifically, the edges where the first resin part 1 and the second resin part 2 contact each other are provided with an R-angle structure 11, which can effectively avoid the possibility of melting due to the sharp edge due to heat, and is beneficial to improving product quality.

[0046] The present invention also provides a toy, comprising a toy structure or a toy structure molded by using the molding method of the toy structure.

[0047] Embodiment 2:

[0048] The present embodiment provides a toy structure, including a first resin part 1 which is first injection molded, and a second resin part 2 which is later injection molded and can be matched with the first resin part 1 in a rotational form. The second resin part 2 has an assembling hole 21 at a portion away from the first resin part 1, and an end of the assembling hole 21 close to the first resin part 1 has an extension part 211, and the extension part 211 can reach the surface of the first resin part 1, so that part or all of the hot air flow can flow out through the assembling hole 21 when the molten resin flows. By arranging the extension part 211 at the inner side end of the assembling hole 21, it is equivalent to establishing a connecting channel between the assembling hole 21 and the first resin part 1, so that the hot air flow dissipates faster, which can reduce the probability of the appearance of melt points on the surface of the first resin part 1, which is conducive to improving product quality.

[0049] Embodiment 3:

[0050] This embodiment is a preferred example of embodiment 1 and embodiment 2. The toy structure in this embodiment is a joint structure, including a first resin part 1 and a second resin part 2. Figure 1 As shown, the inner side surface of the rubber-coated part is concave to form a first arcuate surface, and the part of the first resin part 1 in contact with the rubber-coated part is a convex second arcuate surface, and the first arcuate surface matches the second arcuate surface. The first resin part 1 and the second resin part 2 cooperate to form a joint, and when the joint rotates, the first arcuate surface slides relative to the second arcuate surface.

[0051] In this embodiment, the melt temperature of the first resin part 1 is 200-230°C, and the melt temperature of the second resin part 2 is 170-200°C, that is, the first resin part 1 and the second resin part 2 have a cross melting temperature of 200°C. In this embodiment, the injection point selection Figure 1 Point B in the prior art Figure 2 Compared with the glue inlet point A in the embodiment, point B as the glue inlet point is farther away from the glue encapsulation position. When the melt flows to the glue encapsulation position, the temperature drops below 200°C, which can effectively avoid the appearance of melt points; if the glue inlet point is arranged at point A, then when the melt just flows in and contacts the glue encapsulation position, the temperature is still very high, which is very likely to cause melt points to appear on the surface of the first resin part 1, thereby causing the surface of the first resin part 1 to be not smooth enough, and the joints to get stuck when rotating, resulting in a bad experience. Therefore, point B is used as the glue inlet point in this embodiment, which greatly reduces the probability of melt points appearing on the surface of the first resin part 1, which is beneficial to improving product quality.

[0052] Embodiment 4:

[0053] This embodiment is a variation of the embodiment 1. The difference from the embodiment 1 is that the portion of the second resin member 2 away from the first resin member 1 has an assembly hole 21. Figure 3 As shown, the assembly hole 21 has an extension portion 211, and the extension portion 211 can reach the surface of the first resin part 1 so that when the molten resin flows, part or all of the hot air flow can flow out through the assembly hole 21, which is different from the prior art. Figure 4 In comparison, the probability of the occurrence of melt spots on the surface of the first resin part 1 can be reduced, which is beneficial to improving product quality.

[0054] Embodiment 5:

[0055] The difference between this embodiment and the embodiments 1 and 2 is that the edges where the first resin part 1 and the second resin part 2 contact each other are both R-angle structures 11, such as Figure 6 As shown, this embodiment adopts R corner processing, which is different from the prior art Figure 7 Compared with the right-angle structure 12 adopted in the embodiment, the probability of occurrence of melt points can be reduced, which is beneficial to improving product quality.

[0056] Taking Example 3 as an example, the working principle of the present invention is as follows:

[0057] like Figure 1 , Figure 3 As shown, the first resin part 1 is firstly injection molded. After the first resin part 1 is injection molded and solidified, the Figure 1Point B in the molding is used as the injection point to inject the second resin part 2. When the molten resin material enters from the injection point B and flows over a certain distance toward the encapsulation position, part of the heat is dissipated, causing the temperature of the molten resin material to drop. When it reaches the encapsulation position, the temperature of the molten resin material is lower than the lowest temperature of the melt of the first resin part 1. Therefore, the appearance of a melt point on the surface of the first resin part 1 can be avoided, which is beneficial to ensuring product quality.
