Description

Technical Field

[0001] The invention relates to the field of injection molds, in particular to a segmented floating demoulding mechanism based on high drop products, and also to an injection mold. Background Art

[0002] At present, in the demoulding process of products with high drop, due to the large contact area, the demoulding force required is large, which can easily cause the cavity to be scratched, cracked or deformed, thereby affecting the molding quality of the barrel body. The existing segmented floating demoulding mechanism divides the mold into multiple sections and sets a floating device between each section to achieve independent floating and position adjustment of each section to adapt to the height difference of the product. This mechanism design can effectively reduce the jamming and deformation of the product during the demoulding process, improve the success rate of demoulding and product quality. However, since the segmented floating demoulding mechanism requires multiple floating sections and floating devices, its stability may be affected. During operation, if the fitting between the floating sections is not tight enough or the adjustment of the floating device is inaccurate, incomplete demoulding may occur.

[0003] The currently disclosed Chinese patent CN114932658A discloses an injection mold for high-drop products, including a fixed mold, a movable mold and a demolding mechanism, wherein the fixed mold is fixedly arranged, a molding groove is arranged in the fixed mold, and the movable mold is suitable for cooperating with the molding groove to form a molding deep cavity for molding a barrel body; the movable mold includes at least one segmented core mold and a base plate, the core mold is installed on the base plate, and the core mold is suitable for cooperating with the molding groove to form a cavity in the barrel body; the demolding mechanism is installed on the base plate and cooperates with the core mold; when demolding, the demolding process includes a first process and a second process; wherein, in the first process: the demolding mechanism is suitable for sequentially driving each segment of the core mold to shrink toward the center of the movable mold, and then sequentially separating the core mold from the side wall of the molded cavity in sections; thereby effectively reducing the demolding force on the barrel body when the core mold is demolded, so as to improve the demolding quality of the barrel body; in the second process: the movable mold drives the demolding mechanism to synchronously move away from the barrel body after molding.

[0004] Although the above patent adopts a segmented floating demolding method, it fails to ensure the stability between the floating segments. If the floating segments are not tightly matched or the adjustment of the floating device is inaccurate, incomplete demolding may occur. Therefore, it is necessary to ensure that the floating segments are tightly matched to avoid looseness or gaps, and to set linkage components between the floating segments to ensure stable demolding.

The first linkage assembly 5 is arranged between the first segmented die 31 and the second segmented die 32. The second linkage assembly 6 is arranged between the first segmented punch 41 and the second segmented punch 42.

[0021] When the barrel body 7 with a high drop is subjected to injection molding, the fixed mold 3 and the movable mold 4 are closed, and a mold cavity for injection molding of the barrel body 7 is formed between the fixed mold 3 and the movable mold 4. As the injection liquid is injected into the mold cavity through the injection port 311, the barrel body 7 is formed after cooling, and the fixed mold 3 and the movable mold 4 are demolded accordingly. During the demolding process, the movable mold 4 drives the second segmented die 32 away from the first segmented die 31. At this time, a part of the outer wall of the barrel body 7 is out of the first segmented die 31, and then the movable mold 4 stops moving. Since the first segmented die 31 and the second segmented die 32 are connected with the first linkage component 5, the second segmented die 32 is separated from the first segmented die 31 under the drive of the first linkage component 5. The first segmented punch 41 and the second segmented die 32 are re-fitted with the first segmented die 31. At this time, the remaining part of the outer wall of the barrel body 7 is separated from the second segmented die 32 and the barrel body 7 is still attached to the movable die 4. Then the movable die 4 continues to move away from the fixed die 3 until the first segmented punch 41 contacts the second frame 2. A distance is left between the fixed die 3 and the movable die 4 for the barrel body 7 to be taken out. Since the second linkage assembly 6 is connected between the first segmented punch 41 and the second segmented punch 42, the second segmented punch 42 is first separated from a part of the inner wall of the barrel body 7 under the drive of the second linkage assembly 6, and then the first segmented punch 41 is separated from the remaining part of the inner wall of the barrel body 7, and finally the barrel body 7 is demoulded.

At this time, a gap is left between every two adjacent segment modules 421. As each segment module 421 moves along the slide groove through the protrusion 4211, until multiple segment modules 421 are fitted together, each segment module 421 is separated from the inner wall of the barrel body 7, so that a part of the inner wall of the barrel body 7 is demolded first.

[0025] When the supplementary insert strip 422 slides along the slot 412 on the first segmented punch 41, the floating sleeve 423 is driven to move by the second linkage assembly 6, so that each supplementary insert strip 422 can enter and exit between two adjacent segmented modules 421, and after the floating sleeve 423 contacts the second segmented die 32, the magnetic suction part 4221 is controlled to attract the supplementary insert strip 422, so that the floating sleeve 423 and the first segmented punch 41 are in a fixed state, and the second segmented die 32 and the floating sleeve 423 are adsorbed together by the first electromagnet 321 and the second electromagnet 322. When the movable die 4 moves away from the fixed die 3, the second segmented die 32 also moves away from the first segmented die 31, and the barrel body 7 is separated from the first segmented die 31.

[0027] When the second segmented die 32 moves away from the first segmented die 31, the first segmented die 31 and the second segmented die 32 are connected together by the first connecting rod 51 and the second connecting rod 52 until the first connecting rod 51 and the second connecting rod 52 tend to be parallel to each other, and the second segmented die 32 moves to the farthest distance relative to the first segmented die 31, and the first shaft 521 axially connected between the first connecting rod 51 and the second connecting rod 52 moves along the track opening on the fixed frame 53, and the first shaft 521 moves from One end of the track opening moves to the other end of the track opening, at which time a portion of the outer wall of the barrel body 7 first separates from the first segmented die 31, and then the reset drive 54 is started, driving the first shaft 521 to move to the original position of the track opening, so that the angle between the first connecting rod 51 and the second connecting rod 52 gradually decreases, and the second segmented die 32 is then fitted with the first segmented die 31, so that the remaining portion of the outer wall of the barrel body 7 separates from the second segmented die 32, completing the segmented demolding between the outer wall of the barrel body 7 and the fixed die 3.

[0029] When the first shaft 521 contacts the block 541, the first electromagnetic driver 5421 is started, and the first electromagnetic driver 5421 drives the first movable frame 542 to move toward the fixed frame 53, so that the push rod 543 pushes the block 541, and the block 541 then moves along the edge of the fixed frame 53, pushing the first shaft 521 to move to the original position, until the first shaft 521 moves into place, and the second segmented die 32 then fits with the first segmented die 31.

[0030] See also Figure 3 , Fig. 9 and Fig.10 As shown, a pressure sensor 5411 facing the first shaft 521 is disposed on the clamping block 541 , and a compression spring 5412 is fixedly connected between the pressure sensor 5411 and the clamping block 541 .

[0031] When the second segmented die 32 moves into position relative to the first segmented die 31, the first shaft 521 contacts the pressure sensor 5411. When the pressure sensor 5411 is pressurized, the compression spring 5412 is compressed. When the pressure sensor 5411 senses the pressure, the first electromagnetic driver 5421 is started, pushing the first shaft 521 back to its original position, effectively completing the second segmented die 32 moving away from or approaching the first segmented die 31.

At this time, all the segment modules 421 can move inward, and then the opening and closing drive The moving member 64 is started, driving all the segment modules 421 to move inward synchronously until they fit together. At this time, the segment modules 421 are separated from the inner wall of the barrel body 7, completing the demoulding of a part of the inner wall of the barrel body 7. Then the separation driving member 63 drives the second shaft rod 621 to move again, thereby controlling the floating sleeve 423 to move toward the direction of the first frame 1, and the angle between the third connecting rod 61 and the fourth connecting rod 62 gradually increases until the barrel body 7 is pushed out of the first segmented punch 41, completing the demoulding of the remaining part of the barrel body 7, and effectively achieving the effect of completely separating the inner wall of the barrel body 7 from the moving mold 4.

Since the second shaft rod 621 is movably engaged in the strip opening on the second movable frame 631, the second movable frame 631 drives the movement of the second shaft rod 621, thereby driving the movement of the third connecting rod 61 and the fourth connecting rod 62, controlling the movement direction of the floating sleeve 423 relative to the first segmented punch 41, effectively and completely combining the second segmented punch 42, and effectively separating the barrel body 7 from the first segmented punch 41 and the second segmented punch 42.
