[0003] However, existing inclined guide post type core pulling mechanisms often lack a locking structure, resulting in poor stability. The side slide is prone to wobbling during mold closing, which reduces the processing quality. Furthermore, existing inclined guide post type core pulling mechanisms often lack the function of quickly installing and removing the core. The core is generally fixed by fixing bolts, which is time-consuming and labor-intensive, reducing installation efficiency. Therefore, there is an urgent need for a multi-directional connector demolding linkage core pulling mechanism to solve the above problems. Utility Model Content

The existing inclined guide post type core pulling mechanism often does not have the function of quickly installing and disassembling the core, and the core is generally fixed by fixing bolts.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional connector demolding linkage core-pulling mechanism, comprising a core-pulling mechanism, a fixing structure, an installation structure, and a core. The core-pulling mechanism includes a guide groove, with a side slider slidably connected to the top of the guide groove. An inclined guide post is slidably connected to the middle of the side slider, and the top of the inclined guide post is fixedly connected to a wedge block.

The insert plate is snapped into the bottom of the side slider. A connecting plate is fixedly connected to the right side of the rotating seat, and an extrusion plate is fixedly connected to the top of the connecting plate. The extrusion plate is snapped into the right side of the side slider. The installation structure includes a fixing seat, which is fixedly connected to the right side of the side slider. A dovetail slider is slidably connected to the fixing seat, and a core is fixedly connected to the right side of the dovetail slider. Threaded rods are threaded to both ends of the fixing seat, and an insert rod is fixedly connected to the side of the threaded rod closest to the middle. The insert rod is inserted into the dovetail slider.
[0006] Preferably, the top of the insert plate is provided with rounded corners, and the bottom insertion hole edge of the side slider is provided with rounded corners.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This multi-directional connector demolding linkage core-pulling mechanism has a fixed structure. When the mold is closed, the side slider moves to the right along the inclined guide post, so that the right side of the side slider abuts against the extrusion plate. The side slider pushes the extrusion plate to the right, so that the extrusion plate rotates through the rotating seat, causing the spring to be compressed and contracted, so that the insert plate is inserted into the insertion hole at the bottom of the side slider. The position of the side slider is locked by the insert plate. When demolding, the side slider no longer abuts against the extrusion plate. The elastic force of the spring pushes the connecting plate upward, so that the support plate moves downward, so that the insert plate is no longer locked against the side slider, realizing automatic unlocking. The fixed structure can lock the side slider when the mold is closed, which improves the stability of the side slider, improves the processing quality, and is easy to use.
[0014] 2. This multi-directional connector demolding linkage core-pulling mechanism is equipped with an installation structure. When the core needs to be installed, the dovetail slider is inserted into the fixed seat. Rotating the first handle causes the threaded rod to rotate, which in turn drives the insertion rod to insert into the dovetail slider, locking it in place. The tapered insertion rod prevents the dovetail slider from wobbling. Rotating the second handle causes the limiting plate to press against the side of the fixed seat, generating a preload force to fix the position of the threaded rod. The installation structure allows for quick installation and removal of the core. It is simple in structure, stable in use, and requires no fixing bolts, improving installation efficiency and making it easy to use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5This utility model provides an embodiment of a multi-directional connector demolding linkage core-pulling mechanism, comprising a core-pulling mechanism 1, a fixing structure 2, an mounting structure 3, and a core 4. The core-pulling mechanism 1 includes a guide groove 11, with a side slider 12 slidably connected to the top of the guide groove 11, and an inclined guide post 14 slidably connected to the middle of the side slider 12. The top of the inclined guide post 14 is fixedly connected to a wedge block 13. The fixing structure 2 includes a rotating shaft 21, with the guide groove 11 rotatably connected to both ends of the rotating shaft 21, and a rotating seat 22 rotatably connected to the middle of the rotating shaft 21. A support plate 23 is fixedly connected to the left side of the rotating seat 22, and an insert plate 24 is fixedly connected to the top of the support plate 23. The insert plate 24 is snapped into the bottom of the side slider 12. A connecting plate 25 is fixedly connected to the right side of the rotating seat 22. The top of 25 is fixedly connected to the extrusion plate 26, which snaps onto the right side of the side slider 12. The mounting structure 3 includes a fixing seat 31, which is fixedly connected to the right side of the side slider 12. The fixing seat 31 is slidably connected to the dovetail slider 32, and the right side of the dovetail slider 32 is fixedly connected to the core 4. Both the front and rear ends of the fixing seat 31 are threadedly connected to threaded rods 34. The side of the threaded rod 34 closest to the middle is fixedly connected to the insertion rod 35, which is inserted into the dovetail slider 32. The mounting structure 3 enables the quick installation and disassembly of the core 4. The structure is simple, stable in use, and requires no fixing bolts, thus improving installation efficiency. The fixing structure 2 can lock the side slider 12 when the mold is closed, improving the stability of the side slider 12 and the processing quality.
[0023] Furthermore, the top of the insert plate 24 is provided with rounded corners, and the bottom insertion hole edge of the side slider 12 is provided with rounded corners. The insert plate 24 is inserted into the insertion hole at the bottom of the side slider 12, and the position of the side slider 12 is locked by the insert plate 24.
[0024] Furthermore, a round hole is provided at the top right end of the guide groove 11, and a spring 27 is provided inside the round hole. One end of the spring 27 is fixedly connected to the inner wall of the core pulling mechanism 1, and the other end of the spring 27 is fixedly connected to the bottom of the connecting plate 25. When the mold is closed, the extrusion plate 26 rotates through the rotating seat 22, causing the spring 27 to be compressed by pressure. When the mold is demolded, the side slider 12 no longer presses against the extrusion plate 26, and the elastic force of the spring 27 pushes the connecting plate 25 upward.
[0025] Furthermore, the threaded rod 34 is fixedly connected to the grip 33 on the side away from the middle, and the threaded rod 34 is threadedly connected to the grip 36. Both the grip 33 and the grip 36 are hexagonal grips, and the surface is provided with an anti-slip coating. The anti-slip coating prevents slippage when rotating the grip 33 and the grip 36, and the hexagonal grip is easier to hold.
[0026] Furthermore, a limiting plate 37 is fixedly connected to the side of the second grip 36 near the middle. The limiting plate 37 is threadedly connected to the threaded rod 34. The limiting plate 37 abuts against the side of the fixed seat 31. Rotating the second grip 36 causes the limiting plate 37 to abut against the side of the fixed seat 31, thereby generating a preload force to fix the position of the threaded rod 34.
[0027] Furthermore, the insertion rod 35 is a tapered insertion rod, and the front and rear sides of the dovetail slider 32 are provided with tapered grooves corresponding to the insertion rod 35. The inner wall of the tapered groove is ground. The threaded rod 34 drives the insertion rod 35 to be inserted into the dovetail slider 32, so that the insertion rod 35 locks the dovetail slider 32.
[0028] Working principle: During use, when the mold is closed, the side slider 12 moves to the right along the inclined guide post 14, so that the right side of the side slider 12 abuts against the extrusion plate 26. The side slider 12 pushes the extrusion plate 26 to the right, causing the extrusion plate 26 to rotate through the rotating seat 22. This causes the spring 27 to contract under pressure, allowing the insert plate 24 to engage with the insertion hole at the bottom of the side slider 12. The insert plate 24 locks the position of the side slider 12. When demolding, the side slider 12 no longer abuts against the extrusion plate 26. The elastic force of the spring 27 pushes the connecting plate 25 upward, causing the support plate 23 to move downward, so that the insert plate 24 no longer engages with the side slider 12, achieving automatic unlocking. The fixing structure 2 can lock the side slider 12 during mold closing, improving efficiency. The stability of the side slider 12 improves processing quality and facilitates use. When the core 4 needs to be installed, insert the dovetail slider 32 into the fixed seat 31, rotate the first handle 33 to drive the threaded rod 34 to rotate, and the threaded rod 34 drives the insertion rod 35 to be inserted into the dovetail slider 32, so that the insertion rod 35 locks the dovetail slider 32. The tapered insertion rod prevents the dovetail slider 32 from shaking. Rotate the second handle 36 to make the limiting plate 37 abut against the side of the fixed seat 31, thereby generating a pre-tightening force to fix the position of the threaded rod 34. The installation structure 3 can realize the quick installation and disassembly of the core 4. The structure is simple, stable in use, and does not require fixing bolts, which improves installation efficiency and facilitates use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
