Abstract
Description
Technical Field
[0001] This utility model relates to the field of trendy toy production technology, and in particular to a fine curved surface mold for trendy toys. Background Technology
[0002] As a rapidly rising cultural consumer product category in recent years, trendy toys rely heavily on their exquisite curved shapes for their visual appeal. From smooth character outlines and full muscle lines to complex decorative textures, all of these depend on the support of high-precision molds.
[0003] When producing trendy toys using traditional molds, the rigidity of the metal cavity and the limitations of replicating details often result in poor molding of delicate parts, especially small structures such as finger joints and hairline textures, which are prone to missing glue, deformation, or blurred textures, resulting in serious loss of details in the finished product. At the same time, metal molds have poor adaptability to demolding undercut curved surfaces, which can easily cause damage to details.
[0004] Therefore, this utility model proposes a fine curved surface mold for trendy toys. Utility Model Content
[0005] The purpose of this invention is to provide a fine curved surface mold for trendy toys to solve the above-mentioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fine curved surface mold for trendy toys includes a top plate, an upper template, a lower template, a limiting guide post, and a bottom plate. The upper template is located above the lower template, and the limiting guide post is movably sleeved between the middle of the upper template and the lower template.
[0008] The assembly component, located at the connection between the lower template and the silicone mold, includes a fixed connecting plate fixed to the bottom of the lower template, a cylinder connected to the bottom of the fixed connecting plate, a square linkage plate set at the output end of the cylinder, and a transmission rod movably connected to the outer edge of the square linkage plate. One end of the transmission rod is movably sleeved with an extension rod, and the top of the extension rod is fixedly connected with a connecting push plate. Limiting pins are installed at equal intervals on one side of the connecting push plate.
[0009] Furthermore, a limiting slider is fixedly connected to the top of the fixed connecting plate. The limiting slider is cross-shaped, and each set of extended sides is wedge-shaped. Each set of extended sides of the limiting slider is movably sleeved with one set of connecting push plates.
[0010] Furthermore, the fixed connecting plate and the limiting slider are arranged in a cross shape, and a sliding groove is provided at the bottom of the intersection of the fixed connecting plate and the limiting slider. The interior of the sliding groove is slidably connected to the extension rod.
[0011] Furthermore, the top of the lower template is attached to the upper template, and four sets of limiting guide columns are movably sleeved inside both the upper and lower templates. The top ends of the four sets of limiting guide columns movably sleeved inside the upper template are fixedly connected to the top plate, and the bottom ends of the four sets of limiting guide columns movably sleeved inside the lower template are fixedly connected to the bottom plate.
[0012] Furthermore, a drive shaft is movably sleeved inside the top plate, and the output end of a motor is fixedly connected to the front of the drive shaft. The outer wall of the motor is fixedly connected to the top plate, and an eccentric circle is fixedly connected to the outer wall of the drive shaft. The eccentric circle is eccentrically connected to the drive shaft, and the bottom end of the eccentric circle is in contact with the upper template.
[0013] Furthermore, the upper and lower templates are provided with expansion grooves at their four internal corners, and the limiting guide post is fixed with a limiting collar that forms a movable connection with the expansion groove.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. By embedding a silicone mold inside a metal mold and using multiple sets of limiting pins for stable engagement from four sides, the silicone mold and the lower template fit tightly together, effectively reducing seams and ensuring the detail of the trendy toy. When replacing, the cylinder-driven linkage mechanism can quickly disengage the limiting pins from the mold, easily completing the silicone mold replacement. This ensures production details and allows for quick replacement when the silicone mold is damaged, reducing production interruption losses.
[0016] 2. After injection molding, the motor drives the eccentric circle to rotate, which, together with the spring, causes the template to vibrate regularly. This effectively removes air from the fine gaps and prevents air bubbles from appearing on the surface of the toy. At the same time, the limiting collar on the outer wall of the limiting guide post provides reasonable space for the template to vibrate and limits it during demolding, ensuring effective separation of the template and comprehensively guaranteeing the precision and structural stability of the toy production.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] Please see Figures 1 to 5 As shown, the trendy toy fine curved surface mold provided by this utility model includes a top plate 1, an upper template 3, a lower template 4, a limiting guide post 5, and a bottom plate 7. The upper template 3 is located at the upper end of the lower template 4, and the limiting guide post 5 is movably sleeved in the middle of the upper template 3 and the lower template 4.
[0027] The assembly component, located at the connection between the lower template 4 and the silicone mold 11, includes a fixed connecting plate 13 fixed to the bottom of the lower template 4, a cylinder 19 connected to the bottom of the fixed connecting plate 13, a square linkage plate 18 set at the output end of the cylinder 19, and a transmission rod 16 movably connected to the outer edge of the square linkage plate 18. One end of the transmission rod 16 is movably sleeved with an extension rod 17, and the top of the extension rod 17 is fixedly connected with a connecting push plate 15. Limiting pins 14 are installed at equal intervals on one side of the connecting push plate 15.
[0028] The top of the fixed connecting plate 13 is fixedly connected to a limiting slider 12. The limiting slider 12 is cross-shaped, and each set of extended sides is wedge-shaped. Each set of extended sides of the limiting slider 12 is movably connected to one set of connecting push plates 15.
[0029] The fixed connecting plate 13 and the limiting slider 12 are arranged in a cross shape, and a groove is provided at the bottom of the intersection of the fixed connecting plate 13 and the limiting slider 12. The inside of the groove is slidably connected to the extension rod 17.
[0030] In the production of trendy toys, for parts requiring extremely high detail, an optimized solution can be adopted: embedding a silicone mold 11 inside the corresponding metal mold. To ensure a stable connection between the silicone mold and the metal mold, a limiting mechanism is specially set at the rear end of the silicone mold 11, and multiple fixing structures ensure the complete presentation of production details.
[0031] When it is necessary to replace or install the silicone mold 11, firstly, the output end of the control cylinder 19 extends outward, and the resulting thrust drives the square linkage plate 18 to move smoothly outward in sync. During the movement of the square linkage plate 18, it will pull the four sets of transmission rods 16 that are internally movable to achieve synchronous rotation. Then, through the transmission effect of the extended rod 17, it drives the connecting push plate 15 to slide inward on the surface of the limiting slider 12, so that the limiting pins 14 fixed on the surface of the connecting push plate 15 are simultaneously disengaged from the lower template 4 and the silicone mold 11. At this time, the operator can easily take out the silicone mold 11 from the other side of the lower template 4 for replacement. Multiple sets of limiting pins 14 form an all-round stable sleeve limit from the four sides of the silicone mold 11, so that the edge of the silicone mold 11 is tightly fitted with the lower template 4, effectively reducing or avoiding the generation of connection gaps. While ensuring the detail, it also fully maintains the fine texture of other parts of the trendy toy.
[0032] Because silicone material is inherently soft, it is prone to wear and damage due to frequent stress during long-term production. This design, which allows for quick replacement of local molds, enables timely replacement of damaged silicone molds, minimizing production interruptions and material waste caused by mold problems and significantly reducing production losses.
[0033] Example 2
[0034] Based on Example 1, please refer to Figures 1 to 5 As shown, the top of the lower template 4 is attached to the upper template 3. Both the upper template 3 and the lower template 4 have four sets of limiting guide columns 5 that are movably fitted inside. The top of the four sets of limiting guide columns 5 that are movably fitted inside the upper template 3 are fixedly connected to the top plate 1, and the bottom of the four sets of limiting guide columns 5 that are movably fitted inside the lower template 4 are fixedly connected to the bottom plate 7.
[0035] The top plate 1 is movably connected to the drive shaft 10. The output end of the motor 2 is fixedly connected to the front of the drive shaft 10. The outer wall of the motor 2 is fixedly connected to the top plate 1. The outer wall of the drive shaft 10 is fixedly connected to the eccentric circle 9. The eccentric circle 9 is eccentrically connected to the drive shaft 10, and the bottom end of the eccentric circle 9 is in contact with the upper template 3.
[0036] The upper template 3 and the lower template 4 are provided with expansion grooves at their four internal corners, and the outer side of the limiting guide post 5 is fixed with a limiting collar 8 that forms a movable connection with the expansion groove.
[0037] After the internal injection molding process of the upper mold plate 3 and the lower mold plate 4 is completed, air may be trapped in the complex structure such as fine gaps inside the mold cavity, which may cause defects such as air bubbles on the surface of the finished trendy toys. This device will automatically start the exhaust vibration mechanism after injection molding. By starting the motor 2, the output end of the motor 2 drives the transmission shaft 10 to rotate stably inside the top plate 1, so that the eccentric circle 9 fixed on the transmission shaft 10 rotates around the transmission shaft 10. Since the eccentric circle 9 and the transmission shaft 10 adopt an eccentric connection design, when the convex end of the eccentric circle 9 faces down, it will generate a downward thrust, which will drive the upper mold plate 3 and the lower mold plate 4 to move downward synchronously on the surface of the limit guide post 5. When the eccentric circle 9 continues to rotate until the convex end faces up, the four sets of springs 6 set at the bottom of the lower mold plate 4 will release elastic potential energy, pushing the lower mold plate 4 and the upper mold plate 3 to return to the upper position. This cycle repeats, so that the upper mold plate 3 and the lower mold plate 4 will generate regular vibration, thereby helping to fully expel the air inside the mold gaps and ensuring the fineness of the trendy toy surface.
[0038] The upper template 3 and the lower template 4 are provided with expansion grooves at their four corners. Limiting collars 8 are movably sleeved inside the expansion grooves. The inner walls of the limiting collars 8 are fixedly connected to the limiting guide posts 5.
[0039] Meanwhile, on the outer wall of the limiting guide column 5, a limiting collar 8 is set inside the upper template 3 and the lower template 4, which can limit the position of the upper template 3 and the lower template 4, ensuring that the two can be effectively separated during demolding, and also providing reasonable activity space for the vibration process, ensuring the stable operation of the vibration mechanism.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
