Description

Technical Field

[0001] This utility model relates to the field of molding die technology for cycling products, and in particular to a molding die for a helmet aromatherapy shell. Background Technology

[0002] A helmet fragrance shell is a functional component integrated inside a helmet, designed to improve the riding environment by releasing a slow-release fragrance. Its core design must balance safety, comfort, and fragrance diffusion efficiency.

[0003] Currently, the processing molds for injection molding helmet aromatherapy shells are usually made by injecting plastic into the helmet-shaped mold cavity one by one, forming the shape, and then ejecting it. During the ejection process, because the helmet-shaped plastic part has features such as protrusions, grooves, and buckles opposite to the mold opening direction, such as the side buckles, inner wall annular grooves, and fixed structures with hooks on the helmet aromatherapy shell, when the ejector pin ejects vertically, the plastic part cannot be demolded smoothly due to "backlash jamming the moving mold core", and may even be ejected white or cracked.

[0020] This utility model provides a helmet aromatherapy shell molding mold, which includes a moving mold core, a molding shell, a fixed mold core, a moving template, a fixed template, and an ejector assembly. Multiple molding shells are evenly spaced within the moving mold core. The moving mold core is positioned within the moving template. A locking groove is provided on the bottom surface of the fixed mold core. During the upward movement of the moving template, which drives the moving mold core and molding shells, the top surface of the molding shell can be pressed against the inner side of the locking groove.

The injection port delivers the injection plastic downwards to the main injection pipe, which then distributes it evenly into the delivery pipe. Multiple delivery pipes deliver the plastic downwards through the injection pipe into the molding shell. The injection plastic accumulates and forms in the cavity between the molding shell and the moving mold core. When ejecting after molding, the moving mold core moves downwards or backwards. Because the first and second angled ejector pins penetrate the moving mold core, they simultaneously generate two types of motion: following the main motion of the moving mold core and moving with the mold core. The moving mold core moves along the mold opening direction; the oblique ejection motion pushes outward and upward at its preset angle. After these two motions are superimposed, the first and second oblique ejector pins first disengage obliquely from the groove of the molding housing, then continue to push the plastic part, ultimately completely ejecting it from the core of the moving mold core, achieving damage-free demolding. Furthermore, the first and second oblique ejector pins penetrate the moving mold core, and their contact area with the plastic part is usually larger than that of ordinary ejector pins. During ejection, they can disperse the force, reduce local stress concentration in the plastic part, and avoid defects such as whitening and cracking in thin-walled or fragile areas. Simultaneously, the slight "scratching" of the plastic part during the oblique movement can assist in separating the part from the mold. The material improves demolding stability; the entire mold can simultaneously process multiple helmet aromatherapy shells, and can take into account the curved surface characteristics of the finished helmet aromatherapy shell plastic parts. The first and second inclined ejector pins are set around the outside of the molded shell and directly serve as part of the molding component, replacing the complex side core-pulling inserts, simplifying the mold structure. Moreover, the first and second inclined ejector pins are set through the moving mold core, and the contact area with the plastic part is usually larger than that of ordinary ejector pins. When ejecting, they can disperse the force, reduce local stress concentration in the plastic part, avoid defects such as whitening and cracking in thin-walled or fragile parts, improve demolding stability, and even achieve the effect of demolding without damage.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figure 1-6 This utility model embodiment provides a helmet aromatherapy shell molding mold, comprising:

[0035] The fixed template 5 has a limiting groove 51 through it. The limiting groove 51 is provided with a positioning frame 52 inside. The positioning frame 52 is provided with a conveying pipe 53 evenly through it. The conveying pipe 53 passes through the fixed mold core 3 and is located at the top of the forming shell 2.

[0036] Ejection assembly 8 includes a first support block 81 and a second support block 82. The top of the first support block 81 and the first support block 82 are respectively provided with a first inclined ejector rod 83 and a second inclined ejector rod 84. The ends of the first inclined ejector rod 83 and the second inclined ejector rod 84 are provided with undercut blocks. The first inclined ejector rod 83 and the second inclined ejector rod 84 pass through the moving template 4 and the moving mold core 1 in sequence, and the undercut blocks are provided on the outside of the forming sleeve 2.

[0037] This embodiment provides a helmet aromatherapy shell molding mold, which has a moving mold core 1, a molding shell 2, a fixed mold core 3, a moving template 4, a fixed template 5, and an ejector assembly 8. Multiple molding shells 2 are evenly spaced within the moving mold core 1. The moving mold core 1 is positioned within the moving template 4. A locking groove 31 is provided on the bottom surface of the fixed mold core 3. During the upward movement of the moving template 4, which drives the moving mold core 1 and molding shells 2, the top surface of the molding shells 2 can be pressed against the inner side of the locking groove 31. The undercut blocks of the first inclined ejector rod 83 and the second inclined ejector rod 84 precisely fit with the cavities of the fixed mold core 3 and the moving mold core 1, participating in the molding of the undercut portion of the plastic part, ensuring the dimensional accuracy and surface quality of this area, and together forming the plastic part. In the molding space, for shallow, simple undercuts or complex curved surfaces on plastic parts, the first and second angled ejector pins 83 and 84 can be directly used as part of the molding component, replacing complex side core-pulling inserts, simplifying the mold structure. The injection port 62 delivers the injection plastic downwards to the injection main pipe and then evenly distributes it into the delivery pipe 53.

The injection plastic accumulates and is formed in the cavity between the molding shell 2 and the moving mold core 1. When ejecting after molding, the moving mold core 1 moves downwards or backwards. Because the first and second angled ejector pins 83 and 84 are set through the moving mold core 1, they will generate two kinds of movements simultaneously: follow-up. The main motion of mold core 1: moving along the mold opening direction with the moving mold core; the oblique ejection motion: pushing outward and upward along its own preset tilt angle. After these two motions are superimposed, the first oblique ejector pin 83 and the second oblique ejector pin 84 will first obliquely disengage from the slot of the molding sleeve 2, and then continue to push the plastic part, finally completely ejecting the plastic part from the core of the moving mold core, achieving demolding without damage. Moreover, the first oblique ejector pin 83 and the second oblique ejector pin 84 are set through the moving mold core 1, and the contact area with the plastic part is usually larger than that of ordinary ejector pins. During ejection, the force can be dispersed, reducing local stress concentration in the plastic part and avoiding defects such as whitening and cracking in thin-walled or fragile parts. At the same time, the slight "scratching" of the plastic part during the oblique motion can... The mold assists in separating materials stuck to the mold and improves demolding stability. The entire mold can simultaneously process multiple helmet fragrance shells. Moreover, considering the curved surface characteristics of the finished helmet fragrance shell plastic parts, the first inclined ejector pin 83 and the second inclined ejector pin 84 are set around the outside of the molding shell 2 and directly serve as part of the molding component, replacing the complex side core-pulling insert and simplifying the mold structure. Furthermore, the first inclined ejector pin 83 and the second inclined ejector pin 84 are set through the moving mold core 1, and the contact area with the plastic part is usually larger than that of ordinary ejector pins. During ejection, the force can be dispersed, reducing local stress concentration in the plastic part and avoiding defects such as whitening and cracking in thin-walled or fragile parts. This improves demolding stability and even achieves the effect of demolding without damage.
