[0038] 1, 2 and 6, an injection mold 10 provided in one embodiment of the present application is used to process and mold a product 20. For example, multiple products 20 can be processed simultaneously on the same injection mold 10. The injection mold 10 includes a first mold mechanism 100, a second mold mechanism 200, a first slide mechanism 300 and a second slide mechanism 400; the first mold mechanism 100 and the second mold mechanism 200 can be slidably connected along a first direction.

[0039] Referring to FIG. 2, FIG. 3 and FIG. 4, in some embodiments, the first mold mechanism 100 includes a cover plate 110, a first mold assembly 120 and a slide bar 130, and the cover plate 110 and the first mold assembly 120 may be provided with a glue injection hole 111. The cover plate 110 and the first mold assembly 120 are mutually overlapped along a first direction, and the cover plate 110 and the first mold assembly 120 can slide relative to each other along the first direction. The number of slide bars 130 can be multiple, for example, the number of slide bars 130 can be four, and the four slide bars 130 can be respectively arranged near the four right angles of the cover plate 110, the slide bars 130 are fixedly connected to the cover plate 110, and the slide bars 130 can be slidably arranged in the first mold assembly 120 and the second mold mechanism 200. Therefore, through the guiding effect of the slide bar 130, the relative sliding accuracy between the cover plate 110 and the first mold assembly 120 can be improved, and the relative sliding accuracy between the second mold mechanism 200 and the first mold assembly 120 can also be improved.

[0040] Referring to FIG. 2 , FIG. 3 and FIG. 4 , in some embodiments, the first mold mechanism 100 further includes a fastener 140 , which may be a bolt, etc. The fastener 140 includes a rod portion 141 and a cap portion 142 , the rod portion 141 and the cap portion 142 are coaxially arranged, the rod portion 141 is protrudingly arranged on the end surface of the cap portion 142 in the axial direction, and the cross-sectional dimension of the rod portion 141 is smaller than the cross-sectional dimension of the cap portion 142 . The first mold assembly 120 is provided with a large hole 1211 and a small hole 1212. The large hole 1211 is farther away from the cover plate 110 than the small hole 1212. The large hole 1211 and the first small hole 1212 are coaxially arranged. The aperture of the large hole 1211 is larger than the aperture of the small hole 1212, so that the large hole 1211 and the small hole 1212 form a stepped hole together. The stepped hole runs through the entire first mold assembly 120 along the thickness direction, and the connection between the large hole 1211 and the small hole 1212 has a stepped surface 1213. The rod 141 is inserted into the small hole 1212, so that the rod 141 extends into the cover plate 110 and is fixedly connected to the cover plate 110, for example, the rod 141 is threadedly connected to the cover plate 110. When the injection mold 10 is closed, the cap 142 is located in the large hole 1211, and the cap 142 is spaced from the step surface 1213, that is, there is a certain distance between the cap 142 and the step surface 1213. When the injection mold 10 is opened, the cap 142 can abut against the step surface 1213. In fact, during the mold opening process, relative sliding occurs between the cover plate 110 and the first mold assembly 120, thereby increasing the distance between the cover plate 110 and the first mold assembly 120. When the cap 142 abuts against the step surface 1213, the distance between the cover plate 110 and the first mold assembly 120 increases to the maximum, and the cover plate 110 and the first mold assembly 120 will no longer be able to slide relative to each other. Therefore, the distance between the cap 142 and the step surface 1213 can determine the maximum stroke of relative sliding between the cover plate 110 and the first mold assembly 120. It can be understood that the rod portion 141 can also play a good guiding role in the relative sliding between the cover plate 110 and the first mold assembly 120, thereby improving the stability and sliding accuracy of the relative sliding between the cover plate 110 and the first mold assembly 120.

[0041] Referring to Fig. 6, Fig. 7, Fig. 8 and Fig. 9, in some embodiments, the first mold assembly 120 includes a first mold plate 121 and a first mold core 122, and the first mold plate 121 and the first mold core 122 can be fixedly connected by a detachable connection such as a bolt connection, and the first mold core 122 surrounds the mold cavity 11, and the mold cavity 11 is connected to the injection hole 111, so that the molten plastic liquid injected from the injection hole 111 can enter the mold cavity 11. The first mold core 122 is provided with a first sliding hole 1221, and the first sliding hole 1221 is spaced apart from the two end surfaces of the first mold core 122 in the first direction, so that the first sliding hole 1221 can be a circumferentially closed hole structure, so the first sliding hole 1221 can be understood as a tunnel-type hole structure. The injection mold 10 also includes a core puller, which for the sake of convenience of description can be recorded as a first core puller 610. The first core puller 610 extends a certain length along the first direction. The first core puller 610 is fixedly connected to the first template 121 and / or the first mold core 122. The first core puller 610 extends into the cavity 11. The first core puller 610 is used to form the internal structure of the product 20.

[0042] Referring to FIG. 2 , FIG. 4 and FIG. 7 , in some embodiments, the second mold mechanism 200 includes a base 210 and a second mold assembly 220, and the second mold assembly 220 includes a second mold plate 221 and a second mold core 222. The second mold plate 221 and the second mold core 222 can be fixedly connected by a detachable connection such as a bolt connection, and the second mold core 222 surrounds the molding cavity 11. The base 210 is fixedly connected to the second mold plate 221, and the base 210 and the second mold plate 221 surround a receiving cavity 211. The second mold core 222 is provided with a second sliding hole 2221, and the second sliding hole 2221 is spaced apart from the two end surfaces of the second mold core 222 in the first direction, so that the second sliding hole 2221 can be a circumferentially closed hole structure, so the second sliding hole 2221 can be understood as a tunnel-type hole structure.

[0043] Referring to Figure 4, in some embodiments, the injection mold 10 also includes a core puller. For the convenience of description, the core puller can be recorded as a second core puller 620. The second core puller 620 extends a certain length along the first direction. The second core puller 620 is fixedly connected to the base 210. The second core puller 620 is inserted into the second mold assembly 220 and extends into the cavity 11. The second core puller 620 is used to form the internal structure of the product 20.

[0044] Referring to FIG. 2 , FIG. 4 and FIG. 5 , in some embodiments, the injection mold 10 further includes a push mechanism 500, which includes a push plate 510 and a push pin 520, which are connected to each other. The push plate 510 and the push pin 520 are protrudingly arranged on the push plate 510 along the first direction, so the push pin 520 extends a certain length along the first direction, and the push pin 520 extends into the cavity 11 and contacts the product 20. The second core pull 620 is slidably arranged on the push plate 510, so that the push plate 510 can slide relative to the second core pull 620 along the first direction. The push pin 520 is slidably sleeved outside the second core pull 620, so the push pin 520 can slide relative to the second core pull 620 in the first direction. The push plate 510 is accommodated in the receiving cavity 211 surrounded by the base 210 and the second mold assembly 220, so the push plate 510 can make full use of the space of the receiving cavity 211. During the mold opening process, when the ejector plate 510 slides close to the second mold assembly 220 , the ejector pin 520 can eject the product 20 from the cavity 11 , thereby achieving smooth demolding of the product 20 .

[0045] Referring to FIG. 2 , FIG. 4 and FIG. 5 , in some embodiments, the ejection mechanism 500 further includes a limiting column 530 and an elastic member 540. One end of the limiting column 530 is fixedly connected to the ejection plate 510. The limiting column 530 is slidably arranged in the second template 221. The limiting column 530 extends a certain length along the first direction. By providing the limiting column 530, a good guiding effect can be played on the sliding of the ejection plate 510, thereby improving the sliding stability and sliding accuracy of the ejection plate 510 and the ejector pin 520. The elastic member 540 is at least partially accommodated in the accommodating cavity 211 and sleeved on the limiting column 530. The elastic member 540 abuts between the second template 221 and the ejection plate 510. When an external force pushes the ejection plate 510 to move close to the second template 221 so that the ejector pin 520 can separate the product 20 from the cavity 11, the elastic member 540 stores energy. After the ejector pin 520 ejects the product 20 from the cavity 11 for demolding, the elastic member 540 can release energy so that the elastic member 540 pushes the push plate 510 to move away from the second template 221 until the push plate 510 contacts the base 210 and returns to the initial position. Therefore, the elastic member 540 can reset the push plate 510.

[0046] Referring to FIG. 2 , FIG. 4 and FIG. 7 , in some embodiments, the second mold mechanism 200 may further include a positioning column 230, one end of which is fixed on the base, and the positioning column 230 may be slidably arranged in the ejection plate 510, and the other end of the positioning column 230 may abut against the second template 221, so that the positioning column 230 provides a certain support force for the second template 221. The positioning column 230 is accommodated in the accommodating cavity 211, and the number of the positioning columns 230 may be multiple. The positioning column 230 may play a good guiding role in the sliding of the ejection plate 510, thereby improving the sliding stability and sliding accuracy of the ejection plate 510 and the ejector pin 520.

[0047] Referring to FIG. 6, FIG. 7, FIG. 8 and FIG. 9, in some embodiments, the first slide mechanism 300 includes a plurality of first slide assemblies 301, and the plurality of first slide assemblies 301 are arranged around the same cavity 11 and the same product 20. For example, the same product 20 can be molded by two first slide assemblies 301, and the two first slide assemblies 301 can be spaced 180° along the circumference of the product 20, and the first slide assemblies 301 are used to mold the external structures such as the barbs and holes of the product 20. The first slide assembly 301 includes a first shovel 310 and a first slider 320, and the first shovel 310 and the first slider 320 are slidably connected in a direction that is a first acute angle with the first direction. The first shovel 310 is fixedly connected to the cover plate 110, for example, the first shovel 310 can be fixedly connected to the cover plate 110 by a detachable connection such as a bolt connection; the first shovel 310 can be slidably inserted into the first template 121, so that the first shovel 310 is slidably connected to the first template 121 along the first direction. The first slider 320 is slidably connected to the first template 121 along the second direction, and the second direction is perpendicular to the first direction. The first slider 320 is used to form the external structures such as the barbs and holes of the product 20. The first slider 320 is inserted into the first sliding hole 1221 on the first mold core 122, so that the first slider 320 and the first sliding hole 1221 are slidably matched.

[0048] Referring to FIGS. 10 and 11 , one of the first shovel 310 and the first slider 320 is provided with a first guide cavity 330 and the other is slidably matched with the first guide cavity 330. For example, the first guide cavity 330 can be provided on the first shovel 310, and the first slider 320 is slidably matched with the first guide cavity 330. The extension direction of the first guide cavity 330 forms a first acute angle with the first direction, and points from the first mold mechanism 100 to the second mold mechanism 200 along the first direction, and the distance from the first guide cavity 330 to the mold cavity 11 gradually increases. The cross section of the first guide cavity 330 can be T-shaped or dovetail-shaped.

[0049] Referring to FIG. 10 and FIG. 11 , in some embodiments, the first slide assembly 301 may further include a first connecting member 340, the first shovel 310 has a first inclined surface 311, the first slider 320 has a second inclined surface 321, the first inclined surface 311 and the second inclined surface 321 are in contact with each other and extend in the same direction as the first guide cavity 330. The first guide cavity 330 is provided on one of the first inclined surface 311 and the second inclined surface 321, and the first connecting member 340 is detachably connected to the other, for example, the first guide cavity 330 is provided on the first inclined surface 311, and the first connecting member 340 is detachably connected to the second inclined surface 321, for example, the first connecting member 340 can be detachably connected to the second inclined surface 321 by bolt connection. The cross-sectional shape of the first connecting member 340 is adapted to the first guide cavity 330, so that the first connecting member 340 and the first guide cavity 330 are slidably matched, so the cross-sectional shape of the first connecting member 340 can be T-shaped or dovetail-shaped.

[0050] During the mold opening process, when the cover plate 110 moves away from the first template 121 in the first direction, the first shovel 310 will also follow the cover plate 110 to move relative to the first template 121 in the first direction. Since the extension direction of the first guide cavity 330 forms a first acute angle with the first direction, and points from the first mold mechanism 100 to the second mold mechanism 200 in the first direction, the distance from the first guide cavity 330 to the cavity 11 gradually increases, so that the first shovel 310 can generate a component force in the second direction on the first slider 320 through the first connecting member 340. Under the action of the component force, the first slider 320 can slide relative to the first slide hole 1221 and gradually move away from the cavity 11 and the product 20. After the cover plate 110 moves to the limit position relative to the first template 121, the first slider 320 stops moving relative to the first slide hole 1221 and completely separates from the product 20, thereby eliminating the interference of the first slider 320 on the product 20 in the first direction, so that the product 20 can be smoothly separated from the cavity 11 in the first direction.

[0051] Referring to FIG. 8 , FIG. 9 and FIG. 10 , in some embodiments, the second slide mechanism 400 includes a plurality of second slide assemblies 401, and the plurality of second slide assemblies 401 are arranged around the same cavity 11 and the same product 20. For example, the same product 20 can be molded by two second slide assemblies 401, and the two second slide assemblies 401 can be spaced 180° along the circumference of the product 20, and the second slide assemblies 401 are used to mold the external structures such as the barbs and holes of the product 20. The second slide assembly 401 includes a second shovel 410 and a second slider 420, and the second shovel 410 and the second slider 420 are slidably connected along a direction that is a second acute angle with the first direction. The second shovel 410 is fixedly connected to the first template 121, for example, the second shovel 410 can be fixedly connected to the first template 121 by a detachable connection such as a bolt connection; the second slider 420 is slidably connected to the second template 221 along the second direction, and the second direction is perpendicular to the first direction. The second slider 420 is used to form the external structures such as the barbs and holes of the product 20. The second slider 420 is inserted into the second slide hole 2221 on the second mold core 222, so that the second slider 420 slides with the second slide hole 2221. For two adjacent second slider assemblies 401 for forming two adjacent products 20, the two second sliders 420 of the two second slider assemblies 401 can share a second shovel 410. Of course, the two second sliders 420 can be driven by different second shovels 410.

[0052] Referring to Fig. 8, Fig. 9 and Fig. 10, one of the second shovel 410 and the second slider 420 is provided with a second guide cavity 430 and the other is slidably matched with the second guide cavity 430. For example, the second guide cavity 430 can be provided on the second slider 420, and the second shovel 410 is slidably matched with the second guide cavity 430. The extension direction of the second guide cavity 430 forms a second acute angle with the first direction, and points from the first mold mechanism 100 to the second mold mechanism 200 along the first direction, and the distance from the second guide cavity 430 to the mold cavity 11 gradually increases. The cross section of the second guide cavity 430 can be T-shaped or dovetail-shaped.

[0053] Referring to FIG. 8 , FIG. 9 and FIG. 10 , in some embodiments, the second slide assembly 401 may further include a second connecting member 440, the second shovel 410 has a first inclined surface 411, the second slider 420 has a second inclined surface 421, the first inclined surface 411 and the second inclined surface 421 are in contact with each other and extend in the same direction as the second guide cavity 430. The second guide cavity 430 is provided on one of the first inclined surface 411 and the second inclined surface 421, and the second connecting member 440 is detachably connected to the other, for example, the second guide cavity 430 is provided on the second inclined surface 421, and the second connecting member 440 is detachably connected to the first inclined surface 411, for example, the second connecting member 440 can be detachably connected to the first inclined surface 411 by bolt connection. The cross-sectional shape of the second connecting member 440 is adapted to the second guide cavity 430, so that the second connecting member 440 and the second guide cavity 430 are slidably matched, so the cross-sectional shape of the second connecting member 440 can be T-shaped or dovetail-shaped.

[0054] During the mold opening process, when the first template 121 moves away from the second template 221 along the first direction, the second shovel 410 will also follow the first template 121 to move relative to the second template 221 along the first direction. Since the extension direction of the second guide cavity 430 forms a second acute angle with the first direction, and points from the first mold mechanism 100 to the second mold mechanism 200 along the first direction, the distance from the second guide cavity 430 to the cavity 11 gradually increases, so that the second shovel 410 can generate a component force along the second direction on the second slider 420 through the second connecting member 440. Under the action of this component force, the second slider 420 can slide relative to the second slide hole 2221 and gradually move away from the cavity 11 and the product 20. After the second template 221 moves a set distance relative to the first template 121, the second slider 420 stops moving relative to the second slide hole 2221 and completely separates from the product 20, thereby eliminating the interference of the second slider 420 on the product 20 along the first direction, so that the product 20 can be smoothly separated from the cavity 11 along the first direction.

[0055] In some embodiments, the first acute angle and the second acute angle are equal, so the first guide cavity 330 and the second guide cavity 430 extend in the same direction. This can simplify the manufacturing process, thereby reducing the manufacturing cost of the injection mold 10; on the other hand, it can improve the smoothness of the movement of the first slider 320 and the second slider 420, thereby reducing jamming and ultimately improving the demolding efficiency of the product 20. When closing the mold, the first slider 320 and the second slider 420 overlap each other, which can simplify the structure of the injection mold 10, thereby realizing a compact design of the injection mold 10.

[0056] The working principle of the injection mold 10 is described below:

[0057] In the first step, the injection mold 10 is closed, molten plastic is injected into different cavities 11 through the injection holes 111 , and the molten plastic is gradually cooled under a certain pressure so that the molten plastic is solidified to form a product 20 .

[0058] In the second step, the first mold assembly 120 and the entire second mold mechanism 200 move away from the cover plate 110, so that the first shovel 310 pushes the first slider 320 to gradually move away from the product 20 in the first slide hole 1221. After the cover plate 110 moves to the limit position relative to the first mold assembly 120, the first slider 320 completely withdraws from the product 20, thereby eliminating the interference of the first slider 320 on the product 20 along the first direction.

[0059] In the second step, the first mold assembly 120 can be fixed, and the second mold mechanism 200 moves away from the first mold assembly 120, so that the first core puller 610 gradually withdraws from the product 20. The second shovel 410 pushes the second slider 420 to gradually move away from the product 20 in the second slide hole 2221. After the second mold mechanism 200 moves to the extreme position relative to the first mold assembly 120, the second slider 420 completely withdraws from the product 20, thereby eliminating the interference of the second slider 420 on the product 20 along the first direction. At this time, the first core puller 610 will also completely withdraw from the product 20.

[0060] In the third step, since the first slider 320 and the second slider 420 have withdrawn from the product 20 to eliminate the interference with the product 20 along the first direction, the ejector plate 510 can be pushed to move, so that the ejector pin 520 ejects the product 20 from the cavity 11 of the second mold assembly 220. At this time, the product 20 is completely separated from the cavity 11 and demolding is successfully achieved.

[0061] Since the multiple first sliders 320 in the multiple first slider assemblies 301 can mold the appearance structures at different positions of the product 20, and the multiple second sliders 420 in the second slider assemblies 401 can mold the appearance structures at different positions of the product 20, that is, the first sliders 320 and the second sliders 420 can simultaneously mold the appearance structures at different positions of the product 20. Therefore, the external structure of the product 20 is molded at one time by the same injection mold 10, effectively avoiding the external structure of the product 20 from being molded by multiple different equipment, thus reducing the transfer time and processing time of the product 20 between different equipment, thereby improving the production efficiency of the injection mold 10 for the product 20.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
