Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a hardware embedded injection mold core structure device for preventing scratches. Background Art

[0002] During the injection molding process of hardware products, direct contact and friction between the mold and the product often cause scratches on the product surface, affecting the product's appearance quality and market acceptance. Traditional mold core structures often use sliding friction during demolding. This friction method not only increases the friction force on the product surface, but also easily causes scratches. Therefore, it is particularly important to develop a mold core structure device that can effectively prevent hardware products from being scratched during the injection molding process.

[0003] After searching, the patent number is 201821702398.3, and the name is a utility model of a scratch-resistant mold core structure and mold, which includes a mold core and an insert provided in the mold core, the insert is provided with a slot for injection molding, and a roller is provided around the slot; the roller is rotatably connected to the insert by a pin; a pad is provided on the side of the insert away from the open end of the slot; the mold core is also provided with a guide hole; the mold core is also provided with a positioning angle for positioning the mold core structure direction. The mold includes an upper mold core and any one of the mold core structures described above, and the mold core structure is arranged relative to the upper mold core. In this utility model, there is point contact between the mold core structure and the hardware, and rolling friction occurs during demoulding, which reduces the friction force on the hardware, reduces scratches on the hardware, and improves the product yield; at the same time, the utility model is provided with a positioning angle to facilitate the positioning of the mold core structure and ensure the accuracy of injection molding. However, there are still disadvantages to a certain extent, such as:

[0004] Hardware is formed by injecting materials into the mold structure. The existing mold structure contacts the hardware through rollers. The rotation of the rollers can prevent the hardware from contacting the inner wall of the mold structure and causing scratches. However, when the rollers are running for a long time or are invaded by foreign objects, they may get stuck or become inflexible due to insufficient lubrication or foreign object jamming, which will affect the demoulding effect and increase the risk of scratches, which is not conducive to human use.

[0023] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments;

[0024] Example 1:

[0025] The present application provides a mold core structure device for hardware embedded injection molding to prevent scratches, comprising a mold core body 1; an insert 4 is installed inside the mold core body 1, an injection hole 401 is provided inside the insert 4, a roller 402 is rotatably mounted on the outer surface of the insert 4 near the injection hole 401, and a processing mechanism 5 is installed inside the insert 4 near the outer side of the roller 402;

[0026] The processing mechanism 5 includes a fixed frame 501, a sponge 502 and a flow channel 503. The fixed frame 501 is installed on the outside of the insert 4 near the roller 402. The sponge 502 is provided on the outer surface of the fixed frame 501 near the roller 402. The flow channel 503 is provided inside the insert 4 near the top of the fixed frame 501.

[0027] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the injection hole 401 is used for injection molding of hardware, and the outer surface of the roller 402 contacts the outer surface of the hardware formed inside the injection hole 401. The rotation of the roller 402 can prevent the outer surface of the hardware from directly contacting the insert 4 and causing scratches. The processing mechanism 5 can process the roller 402 to improve its lubricity. The sponge 502 is set inside the fixed frame 501, and the flow channel 503 is connected to the sponge 502. The outer surface of the other side of the roller 402 contacts the sponge 502. By injecting lubricating oil into the flow channel 503, the sponge 502 is filled with lubricating oil. When the roller 402 rotates, the sponge 502 can directly apply the lubricating oil to the surface of the roller 402, thereby improving the lubricity of the roller 402 and preventing it from getting stuck.

[0028] Furthermore, guide holes 101 are provided inside the four corners of the mold body 1;

[0029] Specifically, such as Figure 1 As shown, in order to achieve the positioning and merging of the mold core body 1 with other mold cores, the guide hole 101 can facilitate the insertion of the guide column, so that the mold core body 1 can be horizontally aligned when merging with other mold cores, thereby positioning the mold core body 1 with other mold cores.

[0030] Furthermore, positioning angles 102 are provided at the four corners of the mold body 1, and cushioning pads 103 are provided on the surfaces of the positioning angles 102;

[0031] Specifically, such as Figure 1 As shown, in order to achieve buffering protection when the mold core main body 1 is merged with other mold cores, when the mold core main body 1 is merged with other mold cores, the four corners of the other mold cores will be stuck inside the positioning angle 102, and the buffer pad 103 is composed of buffering material. The buffer pad 103 can reduce the impact force generated when the mold core main body 1 is merged with other mold cores.

[0032] Furthermore, a fixing groove 2 is provided inside the mold core body 1, a cushion block 3 is installed inside the fixing groove 2, and an insert 4 is connected to the top of the cushion block 3;

[0033] Specifically, such as Figure 3As shown, in order to support the insert 4, the insert 4 is arranged inside the fixing groove 2, and the top of the insert 4 can be supported by the pad 3 to keep the insert 4 stable.

[0034] Furthermore, pins 403 are installed at both ends of the roller 402, and the pins 403 are connected to the insert 4;

[0035] Specifically, such as Figure 2 As shown, in order to achieve the connection between the roller 402 and the insert 4, the roller 402 is connected to the insert 4 through a pin 403, and the pin 403 can fix the roller 402.

[0036] Furthermore, a plug 6 is provided at the top of the flow channel 503;

[0037] Specifically, such as Figure 1 and Figure 4 As shown, in order to prevent foreign matter from flowing into the interior of the flow channel 503, the plug 6 is stuck inside the flow channel 503 to seal the interior of the flow channel 503, thereby preventing foreign matter from entering the interior of the flow channel 503 and contaminating the lubricating oil.

[0038] Working principle: The roller 402 is connected to the insert 4 through the pin 403. The hardware is formed by injecting material into the injection hole 401. The outer surface of the roller 402 contacts the outer surface of the hardware formed inside the injection hole 401. The rotation of the roller 402 can prevent the outer surface of the hardware from directly contacting the insert 4 and causing scratches. When the roller 402 rotates, the sponge 502 can directly apply lubricating oil to the surface of the roller 402, thereby improving the lubricity of the roller 402.

[0039] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting.
