Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a neck structure suitable for a building block figure and a toy thereof. Background Art

[0002] The shrinkage rate of plastic refers to the percentage difference between the size of the plastic part at the molding temperature and the size after it is taken out of the mold and cooled to room temperature. It reflects the degree of size reduction of the plastic part after it is taken out of the mold and cooled. Factors that affect the shrinkage rate of plastic include: plastic type, molding conditions, mold structure, etc. The shrinkage rate of different polymer materials is different. Secondly, the shrinkage rate of plastic is also closely related to the shape of the plastic part, the complexity of the internal structure, whether there are inserts, etc.

[0003] In the current production process of building block body parts, especially cylindrical structural parts (such as necks), if they are made into solid parts, they often have dents and quality defects due to shrinkage and deformation. In order to reduce the impact of shrinkage, the production method of stealing glue is often adopted to hollow out the inside of the parts, making the entire parts into thin-walled parts. Although thin-walled parts also have very small shrinkage, the impact on the appearance quality is small. Figure 5 , Figure 6 As shown in the figure, this part is the neck part of the figure, with the upper end connected to the head and the lower end connected to the body. The shape needs to meet the symmetrical shape requirements no matter how it rotates. Therefore, it is impossible to meet the uniform wall thickness requirements by stealing glue. If the neck part is made into a solid part, it will inevitably produce obvious shrinkage marks, deformation and other quality defects ( Figure 7 The dents in the figure are caused by shrinkage of the plastic parts), which will inevitably lead to uneven wall thickness at the connection between the neck part and the upper and lower parts, affecting product quality.

[0049] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0050] The utility model provides a neck structure suitable for a building block figure, such as Figure 1 , Figure 2As shown, it includes a building block body 1 located in the middle, a first building structure 2 arranged on the upper part of the building block body 1, and a second building structure 3 arranged on the lower part of the building block body 1. The first building structure 2 is used to assemble the head of the building block man, and the second building structure 3 is used to assemble the body part of the building block man. The first building structure 2 and the second building structure 3 can adopt a variety of building structures. Specifically, the first building structure 2 can be designed as a male head or a female head, and the second building structure 3 can also be designed as a male head or a female head. It can be flexibly designed according to the overall appearance of the toy, convenient assembly and other requirements to meet the needs of fun and convenient assembly.

[0051] The building block 1 in this embodiment is a rod-shaped structure with a concave middle and convex ends along the axial direction, and the two ends are symmetrical; the thickness of the building block (1) at the thickest position is a, the thickness at the thinnest position is b, and the height difference between the thickest position and the thinnest position is d. Fig.12 As shown, when the modeling optimization parameter f satisfies 0.02<f<0.15, it is within the modeling optimization range where shrinkage is controllable, where: The outer surface of the building block 1 has a smooth transition structure from the thickest position to the thinnest position, making the appearance more beautiful. Fig.13 As shown, the modeling optimization parameter f satisfies: Since the modeling optimization parameter f is 0.11, which is within the range of 0.02 to 0.15, the shrinkage is within the controllable modeling optimization range. At the same time, the material used for the building block 1 is ABS, and the maximum shrinkage of ABS is generally around 0.8%, while the plane shrinkage drop that can usually be clearly seen by the naked eye is around 0.05mm, which means that shrinkage will inevitably have a visual impact on the uniform regular modeling. In this embodiment, the shrinkage position of the thicker interface is concentrated, and the shrinkage drop is large. The shrinkage drop of the thinner interface is small relative to the thicker interface. The shrinkage of the thicker interface will also make the final thickness smaller than the thinner interface, avoiding the accidental increase in thickness drop. Therefore, the structure in the utility model greatly weakens the impact of shrinkage on the appearance, so that the appearance changes caused by shrinkage are within the controllable quality range, greatly improving the product yield and reducing the processing cost.

[0052] The building block 1 in this embodiment has an outer peripheral surface with alternating concave and convex shapes along the circumference of the axial direction of the building block 1. The cross section of the building block 1 forms an area from the concave point of the edge to the next concave point in the clockwise direction. A convex point is arranged between two concave points in each area. The cross section of the building block 1 includes n areas, where n is a positive integer from 2 to 10, wherein n is preferably 4. Figure 3As shown. The circumferential direction of the building block 1 along the axial direction of the building block 1 is designed to have a concave and convex shape. The same mechanism as the axial direction can also achieve the effect of weakening the impact of shrinkage on the appearance and making the appearance change caused by shrinkage within the controllable quality range. In a possible embodiment, any two regions in the cross section of the building block 1 are axially symmetrical or centrosymmetrical, for example, two adjacent regions in the cross section are axially symmetrical; for another example, when n is 4, two non-adjacent regions are arranged centrosymmetrically.

[0053] In order to enhance the overall aesthetics, the outer surface of the building block 1 has a smooth transition from concave points to convex points, and the corners at both ends of the building block 1 are chamfered, which is both safe and beautiful. The utility model forms a relatively obvious wall thickness distinction in the concave and convex texture design, guides the shrinkage direction to a certain extent when shrinkage occurs, complements the original shape, introduces the deformation problem in advance, controls it within a reasonable range, greatly reduces the impact of shrinkage on the overall aesthetics of the toy, and meets the symmetry requirements.

[0054] The utility model also provides a toy, including a neck structure suitable for a building block figure, such as a building block figure toy, such as Figure 4 As shown, the neck of the building block man toy can improve the yield of toy parts and reduce costs without affecting the player's experience by setting the neck structure of the utility model.

[0055] The toy in the present utility model further comprises a waist structure 4 and a waist decoration 5, such as Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the waist structure 4 includes a frame 41, a rear trouser piece 42 that can be spliced ​​to the rear end of the frame 41, a front trouser piece 43 that can be spliced ​​to the front end of the frame 41, and a ball head sleeve 44 that can be spliced ​​to the left and right ends of the frame 41 respectively. The two ends of the bottom of the frame 41 are respectively provided with cylindrical protrusions, and the ball head sleeve 44 is mounted and spliced ​​on the protrusions.

[0056] The two sides of the top of the rear trousers 42 are respectively provided with second protrusions 421, and the two sides of the top of the front trousers 43 are respectively provided with first protrusions 431. The rear trousers 42 and the front trousers 43 are respectively spliced ​​on the frame 41 to form waist trousers. At this time, the first protrusion 431 and the second protrusion 421 contact and abut against each other to form a male head. The waist decoration 5 is spliced ​​on the outside of the waist trousers and can limit and lock the waist trousers. The waist trousers of the utility model adopt a split structure and introduce a belt decoration 5 for position locking. The waist trousers structure separated from the front and back, the semicircular structure of the protrusion is locked by the belt part. After the shape is assembled, it will not fall off from the front and back, which increases the stability of the toy. At the same time, when disassembling, if the ball head is disassembled, the waist trousers can be directly separated from the front and back, avoiding the problem of the need to disassemble in the order of installation caused by making the waist trousers into an integral part in the prior art, achieving the effect of preventing the disassembly sequence and disassembly in no particular order, which increases the fun of the toy.

[0057] The top of the frame 41 has a third assembling structure 411, which can be used to assemble the structure above the waist of the building block. The third assembling structure 411 is a male or female head, for example Fig. 9 The third assembling structure 411 is designed as a male head. Meanwhile, the male head has a splicing hole, which can also be used as a female head.

[0058] In practical applications, the front trousers piece 43 and the back trousers piece 42 can be connected in a variety of ways. The front trousers piece 43 can be directly spliced ​​on the back trousers piece 42 to form a waist trousers; and / or the front trousers piece 43 and the back trousers piece 42 are spliced ​​on the frame 41 to form a waist trousers. The mid-waist trousers of the utility model adopt a split structure, which not only solves the problem of low overall yield rate of the whole piece and high cost of ultrasonic demoulding, but also solves the problem that the overall assembly will lead to difficulty in disassembly, greatly improving the player's experience.
