[0036] Referring to FIG. 1 and FIG. 2 , FIG. 1 shows a schematic diagram of the structure of an injection mold in an embodiment of the present application, and FIG. 2 shows a top view of an injection mold in an embodiment of the present application. The injection mold provided in an embodiment of the present application includes a movable mold mechanism, a fixed mold mechanism 100, a movable mold insert and a fixed mold insert 200. The movable mold mechanism and the fixed mold mechanism 100 can be close to or away from each other. The movable mold mechanism includes a movable mold plate, and the fixed mold mechanism 100 includes a first fixed mold plate 110. The movable mold insert is arranged on the movable mold plate; the fixed mold insert 200 is arranged on the first fixed mold plate 110, and the fixed mold insert 200 is arranged opposite to the movable mold insert, and the cavity between the fixed mold insert 200 and the movable mold insert is a molding station, and the molding station is used for injection molding of the product 10; the fixed mold insert 200 includes a core 210 and a movable component 220, and the core 210 is provided with a lifting channel 210A, and the movable component 220 can be movably arranged in the lifting channel 210A.

[0037] The injection mold described in the embodiment of the present application is provided with a movable mold insert on the movable mold plate, and a fixed mold insert 200 is provided on the fixed mold plate 110. When the mold is closed, the movable mold mechanism and the fixed mold mechanism 100 are closed, and a molding station is formed inside the movable mold insert and the fixed mold insert 200. The plastic raw material is injected into the cavity of the molding station to be processed into a product.

[0038] The injection mold described in the embodiment of the present application, when there is a protrusion extending outward on the inner side of the processed product 10, by setting a movable component 220 in the lifting channel 210A, the gap between the core 210 and the movable component 220 constitutes a cavity of the inner wall, so that the undercut position is set on the movable component 220. When the injection molding is completed, the movable component 220 can push the inner side of the processed product 10 to be demolded with the core 210 first. At this time, the side of the inner wall relative to the movable component 220 has been demolded to make room, and then the side of the undercut position is demolded. Since the other side can be slightly deformed due to the space made available, the undercut position of the raised part will not be scratched, and the demolding is completed by automatic lifting, which has the advantages of good product quality and high production efficiency.

[0039] As shown in Figures 3 to 5, Figure 3 shows a cross-sectional view of an injection mold in an embodiment of the present application, and Figures 4 and 5 show structural schematic diagrams of a fixed mold insert 200 of an injection mold in an embodiment of the present application. In some embodiments, the lifting channel 210A is extended along the mold opening direction, and the movable component 220 includes a first insert 221, a second insert 222 and a third insert 223, and the first insert 221 and the second insert 222 are respectively arranged on both sides of the third insert 223. Gaps are provided between the ends of the first insert 221, the second insert 222 and the third insert 223 and the core 210, and the first insert 221, the second insert 222 and the third insert 223 are respectively provided with a first groove 2211, a second groove 2221 and a third groove 2231 on the side facing the gap, and a protrusion is provided on the inner side wall of the processed product 10, and the inner side wall of the processed product 10 is formed in the gap, and the protrusion is formed in the first groove 2211, the second groove 2221 and the third groove 2231. By setting the movable component 220 as the first insert 221, the second insert 222 and the third insert 223 that are relatively movable, the gaps between the ends of the first insert 221, the second insert 222 and the third insert 223 and the fixed mold insert 200 are the molding cavities of the inner side wall of the processed product 10, and then the first groove 2211, the second groove 2221 and the third groove 2231 form the convex part of the processed product, so that the undercut position can be set on the movable component 220, so that the movable component 220 pushes the processed product 10 to demould the core 210 part first, and then demould the inner convex part, thereby avoiding the quality problem of hard scratches caused by forced demoulding of the undercut position. By separating the movable component 220 into the first insert 221, the second insert 222 and the third insert 223, the three parts can be driven separately, so that the undercut position can be demoulded in sections, reducing the extrusion force when demoulding the undercut position, and reducing the damage of demoulding to the processed product.

[0040] In an optional embodiment, as shown in Figures 3, 5 and 6, the first fixed mold plate 110 is provided with a first accommodating cavity 110A, the end of the movable component 220 away from the fixed mold insert 200 is arranged in the first accommodating cavity 110A, the first insert 221 is provided with a first hanging platform 2212, and the sliding stroke of the first hanging platform 2212 in the first accommodating cavity 110A is a first stroke, the second insert 222 is provided with a second hanging platform 2222, and the sliding stroke of the second hanging platform 2222 in the first accommodating cavity 110A is a second stroke, and the third insert 223 is provided with a third hanging platform 2232, and the sliding stroke of the third hanging platform 2232 in the first accommodating cavity 110A is a third stroke. By setting the first hanging platform 2212 in the first insert 221, the second hanging platform 2222 in the second insert 222, and the third hanging platform 2232 in the third insert 223, the first hanging platform 2212, the second hanging platform 2222, and the third hanging platform 2232 slide in the first accommodating cavity 110A along the demoulding direction. Since the sliding stroke of each insert is the stroke of the hanging platform sliding from the bottom of the first fixed mold plate 110 to abut against the fixed mold insert 200, the height of each hanging platform will determine the length of its sliding stroke.

[0041] In an optional embodiment, the length of the first stroke is equal to the length of the second stroke, and the length of the third stroke is less than the length of the first stroke. That is to say, in the embodiment where the height of the hanging platform determines the sliding stroke, the height of the first hanging platform 2212 is equal to the height of the second hanging platform 2222, and the height of the third hanging platform 2232 is greater than the height of the first hanging platform 2212. By setting the length of the first stroke and the length of the second stroke to be greater than the length of the third stroke, that is, when demolding, the third insert 223 stops moving first, and then the first insert 221 and the second insert 222 continue to move with the processed product 10, thereby achieving graded demolding, thereby reducing the extrusion force of the undercut position during demolding, and reducing the damage of demolding to the processed product.

[0042] Further, as shown in FIG. 7 , the first insert 221 is provided with a first inclined surface 2213, the second insert 222 is provided with a second inclined surface 2223, the third insert 223 is provided with a third inclined surface 2233 and a fourth inclined surface 2234, the third insert 223 is in the shape of a trapezoid, the third inclined surface 2233 and the fourth inclined surface 2234 are waists of both sides of the trapezoid, the first inclined surface 2213 is movably abutted against the third inclined surface 2233, and the second inclined surface 2223 is movably abutted against the fourth inclined surface 2234. By setting the third insert 223 in the shape of a trapezoid, after the third insert 223 stops sliding, the first insert 221 and the second insert 222 can continue to slide toward the center so that the first groove 2211 and the second groove 2221 are separated from the protruding portion in the horizontal direction, without the need for forced demolding, thereby reducing the scratches on the processed product 10.

[0043] In an optional embodiment, as shown in Figure 5, the first fixed mold plate 110 also includes a first mounting member 111 and a second mounting member 112, and the first mounting member 111 and the second mounting member 112 are arranged on both sides of the first accommodating cavity 110A, the first mounting member 111 is provided with a first sliding groove 111A along the mold opening direction, and the second mounting member 112 is provided with a second sliding groove 112A along the mold opening direction, and the third hanging platform 2232 is arranged on both sides of the third insert 223, and the third hanging platforms 2232 on both sides can be slidably arranged in the first sliding groove 111A and the second sliding groove 112A respectively. By setting the first mounting member 111 and the second mounting member 112, the third hanging platform 2232 on both sides can slide in the first sliding groove 111A and the second sliding groove 112A respectively, and the first hanging platform 2212 and the second hanging platform 2231 can also slide between the first mounting member 111 and the second mounting member 112, thereby limiting the sliding directions of the first hanging platform 2212, the second hanging platform 2231 and the third hanging platform 2232, thereby improving the sliding stability of the movable component 220 and making the mold more stable when in use.

[0044] In an optional embodiment, as shown in FIG. 1 and FIG. 3 , the injection mold further includes a lifting mechanism 300, the fixed mold mechanism 100 further includes a second fixed mold plate 120 and a fixed mold base 130, the first fixed mold plate 110 is arranged on the second fixed mold plate 120, the second fixed mold plate 120 is arranged on the fixed mold base 130, and the lifting mechanism 300 is movably arranged on the fixed mold base 130 along the mold opening direction. By setting the lifting mechanism 300, the sliding assembly 220 is driven to slide, and automatic demoulding is realized, and there is no need to use manual demoulding, which has a high degree of automation and has the advantages of high production efficiency.

[0045] Further, as shown in FIG3 , the lifting mechanism 300 includes an ejector pin, a first ejector plate 310 and a second ejector plate 320. The ejector pin is clamped between the first ejector plate 310 and the second ejector plate 320. The ejector pin is arranged corresponding to the position of the movable component 220. The first ejector plate 310 and the second ejector plate 320 drive the ejector pin to abut against the movable component 220. The first ejector plate 310 and the second ejector plate 320 are arranged on the fixed mold base 130. When the mold is opened, the movable mold mechanism drives the first ejector plate 310 and the second ejector plate 320 to move in the mold opening direction, thereby driving the ejector pin to move. The ejector pin will push the movable component 220 to move in the mold opening direction, thereby pushing the processed product 10 to complete demolding.

[0046] In an optional embodiment, as shown in FIG3 , the lifting mechanism 300 further includes a reset elastic member 330, which is disposed between the first lifting plate 310 and the first fixed plate 110. By providing the reset elastic member 330, when the mold is closed after demolding, the reset elastic member 330 pushes the first lifting plate 310 and the second lifting plate 320 back to the initial position, and the reset can be performed automatically without the need for an additional driving device, which has the advantage of a high degree of automation.

[0047] The injection mold described in the embodiment of the present application has the following beneficial effects:

[0048] 1. After the injection molding is completed, the movable component 220 can push the inner side of the processed product 10 to demold the core 210 first. At this time, the inner wall relative to the side of the movable component 220 has been demolded to make room, and then the side of the undercut position is demolded. Since the other side can be slightly deformed due to the space made available, the undercut position of the raised part will not be scratched, and the demolding is completed by automatic lifting, which has the advantages of good product quality and high production efficiency.

[0049] 2. By setting the length of the first stroke and the length of the second stroke to be greater than the length of the third stroke, that is, when demolding, the third insert 223 stops moving first, and then the first insert 221 and the second insert 222 continue to move with the processed product 10, thereby achieving graded demolding, thereby reducing the extrusion force of the undercut position during demolding and reducing the damage of demolding to the processed product.

[0050] 3. By setting the third insert 223 to a trapezoidal shape, after the third insert 223 stops sliding, the first insert 221 and the second insert 222 can continue to slide toward the center so that the first groove 2211 and the second groove 2221 are separated from the raised portion in the horizontal direction, without forced demolding, thereby reducing scratches on the processed product 10.

[0051] 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.
