[0031] like Figure 1-6 As shown, this application embodiment provides a mold opening and closing sequence control mechanism, including a carrier plate 1, and the carrier plate 1 is provided with a first insertion hole 11 and a second insertion hole 12 spaced apart in a first direction;

[0032] The first pin 5, one end of the first pin 5 is movably inserted into the first socket 11;

[0033] The second pin 6 has one end movably inserted into the second socket 12, and the insertion direction of the second pin 6 is opposite to that of the first pin 5.

[0034] The slider 2 has a first groove 13 in the second direction in the carrier plate 1. The slider 2 is slidably disposed in the first groove 13, and the slider 2 passes through the first insertion hole 11 and extends into the second insertion hole 12. The slider 2 is used to limit the first insertion pin 5 after the first insertion pin 5 is pulled out a certain distance. The slider 2 is provided with a pushing mechanism.

[0035] The carrier plate 1 is also provided with a second slide groove 14. The second slide groove 14 is arranged in a second direction. The locking pin 4 is slidably disposed in the second slide groove 14 and is located between the first pin 5 and the second pin 6. The locking pin 4 is used to limit the second pin 6.

[0036] It also includes a fixed mold 7, a first moving mold 8 and a second moving mold 9, which are arranged sequentially from top to bottom. The carrier plate 1 is detachably connected to the first moving mold 8, the other end of the first pin 5 is detachably connected to the fixed mold 7, and the other end of the second pin 6 is detachably connected to the second moving mold 9.

[0037] In this embodiment, the cross-sectional shape and size of the first pin 5 match the first insertion hole 11, and the cross-sectional shape and size of the second pin 6 match the second insertion hole 12, which can improve the reliability of the mechanism; the slider 2 has a through hole, the second direction length of the through hole is greater than the second direction width of the first pin 5, the first pin 5 is movably inserted into the through hole, and the locking pin 4 is cylindrical; the fixed mold 7, the first moving mold 8 and the second moving mold 9 can perform mold opening and closing movements with each other, and the maximum stroke between them is fixed; the first pin 5, the carrier plate 1 and the second pin 6 are respectively detachably installed by bolts;

[0038] When the mold is closed, one end of the slider 2 extends into the second insertion hole 12 and abuts against the contact surface 62 of the first pin 5. One side of the locking pin 4 abuts against the first pin 5, and the other side is engaged with the second pin 6. At this time, the locking pin 4 is located at the end of the second slide groove 14 near the second pin 6.

[0039] During mold opening, the first moving mold 8 and the second moving mold 9 move away from the fixed mold 7 simultaneously. At this time, the first moving mold 8 and the second moving mold 9 do not separate under the action of the locking pin 4. At this time, the first insert pin 5 will gradually withdraw from the first insertion hole 11. After the first insert pin 5 has withdrawn a certain distance, the first insert pin 5 disengages from the locking pin 4 and no longer abuts against the locking pin 4. At this time, the locking pin 4 is no longer restricted by the first insert pin 5. At this time, the mold opening of the fixed mold 7 and the first moving mold 8 is completed. At this time, the stroke distance between the fixed mold 7 and the first moving mold 8 reaches the maximum, and the first moving mold 8 no longer moves. As the second moving mold 9 continues to move away from the fixed mold 7, the second moving mold 9 drives the second pin 6 to be pulled out of the second insertion hole 12. At this time, the locking pin 4 will disengage from the second pin 6 and slide to the end of the second slide groove 14 away from the second pin 6. At this time, the second pin 6 is no longer restricted by the locking pin 4. At this time, the second pin 6 can be smoothly pulled out of the second insertion hole 12. The first moving mold 8 and the second moving mold 9 gradually separate. When the distance between the first moving mold 8 and the second moving mold 9 reaches the maximum stroke, the first moving mold 8 and the second moving mold 9 complete the mold opening.

[0040] When the second pin 6 is gradually pulled out of the second insertion hole 12, after the second pin 6 is separated from the slider 2, the slider 2 is pushed to slide towards the second insertion hole 12 under the action of the pushing mechanism to limit the first pin 5. Its function is to prevent the fixed mold 7 and the first moving mold 8 from closing before the first moving mold 8 and the second moving mold 9 close in the next mold closing.

[0041] During mold closing, the second moving mold 9 drives the second pin 6 closer to the first moving mold 8, so that the second pin 6 gradually inserts into the second insertion hole 12. When the distance between the first moving mold 8 and the second moving mold 9 is zero, the mold closing of the first moving mold 8 and the second moving mold 9 is completed. During this process, the insertion end of the second pin 6 will contact the slider 2 and push the slider 2 back to its original position. At this time, the slider 2 cancels the limit on the first pin 5. As the second moving mold 9 continues to move, it drives the first moving mold 8 to approach the fixed mold 7 together. At this time, the first pin 5 will gradually insert into the first insertion hole 11. When the insertion end of the first pin 5 contacts the locking pin 4, as it continues to insert, it will push the locking pin 4 back to the second slide groove 14 near the end of the second pin 6 and engage with the second pin 6. At this time, the mold closing of the fixed mold 7, the first moving mold 8, and the second moving mold 9 is completed.

[0042] This application achieves precise control over the mold opening and closing sequence and timing through the cooperation between the first pin 5, the second pin 6, the slider 2, and the locking pin 4. At the same time, the structure is simple and compact, requires little assembly space, can achieve dual technical action effects, and is safe, reliable, and highly applicable.

[0043] In one embodiment, a protrusion 51 is provided on the side of the first pin 5 away from the second socket 12.

[0044] In this embodiment, by providing a protrusion 51 on the side of the first pin 5 away from the second socket 12, when the second pin 6 disengages from the slider 2, the slider 2 is pushed to slide towards the second socket 12 under the action of the pushing mechanism. At this time, the slider 2 will lock the protrusion 51, thereby achieving the effect of limiting the position.

[0045] In one embodiment, the upper end of the protrusion 51 is provided with a first inclined surface 511.

[0046] In this embodiment, the first inclined surface 511 faces the side away from the second socket 12. The setting of the first inclined surface 511 can prevent the slider 2 from affecting the removal of the first pin 5 due to the slider 2 not being reset properly when the first pin 5 is pulled out of the first socket 11, thereby improving reliability.

[0047] In one embodiment, the end of the first pin 5 that is inserted into the first socket 11 is provided with a second inclined surface 52 on the side near the locking pin 4.

[0048] In this embodiment, the second inclined surface 52 allows the first pin 5 to smoothly push the locking pin 4 back to its original position during mold closing, further improving reliability.

[0049] In one embodiment, the second pin 6 is provided with a slot 61 on the side near the locking pin 4, and the shape of the slot 61 is adapted to the locking pin 4.

[0050] In this embodiment, the cross-sectional shape of the slot 61 is arc-shaped. When the locking pin 4 is pushed in the opposite direction to the end of the second slide groove 14 near the second pin 6, the side of the locking pin 4 near the second pin 6 will be partially locked into the slot 61, forming a locking connection with the slot 61, thus limiting the second pin 6.

[0051] In one embodiment, the end of the second pin 6 that is inserted into the second socket 12 is provided with a third bevel 63 on the side near the first socket 11.

[0052] In this embodiment, the third inclined surface 63 can smoothly push the slider 2 back to its original position during mold closing, further improving reliability.

[0053] In one embodiment, the pushing mechanism is an elastic element 3, which is disposed at the end of the slider 2 away from the second socket 12.

[0054] In this embodiment, the elastic element 3 includes, but is not limited to, a spring.

[0055] In one embodiment, a guide surface 21 is provided at the end of the slider 2 away from the elastic member 3.

[0056] In this embodiment, the guide surface 21 is also designed to enable the second pin 6 to smoothly push the slider 2 back to its original position, thereby improving the reliability of the mechanism.

[0057] This application also provides a mold, including a mold opening and closing sequence control mechanism of any of the above embodiments.

[0058] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
