[0046] In some embodiments, the top of the support 344 is provided with a "T"-shaped mounting hole 3441, which is connected to the second channel 342. The stop block 345 is also "T"-shaped and is installed in the mounting hole 3441 to reduce the overall height of the limit seat 34.

[0047] The first connecting component 31 includes a first support rod 312 and a first connecting block 313. The first connecting block 313 is fixedly connected to the position seat 23. One end of the first support rod 312 is slidably installed in the first channel 341 and the other end is connected to the first connecting block 313, so that the first connecting component 31 can move together with the position seat 23 and position the position seat 23. The slot 311 is provided on the first support rod 312.

[0048] The second connecting component 32 includes a second support rod 322 and a second connecting block 323. The second connecting block 323 is connected to the lifting component 24. One end of the second support rod 322 is slidably installed in the second channel 342, and the other end is connected to the second connecting block 323, so that the second connecting component 32 can move together with the lifting component 24 to position the lifting component 24.

The limiting seat 34 has a countersunk hole 346 communicating with the second channel 342 on the side away from the sliding seat 23. The countersunk hole 346 and the second channel 342 are coaxially arranged. The second support rod 322 has a threaded hole 3221. One end of the fastener 324 is located in the countersunk hole 346 and the other end is threadedly connected to the threaded hole 3221 to prevent the second connecting component 32 from falling off the limiting seat 34. The fastener 324 can slide in the countersunk hole 346. The fastener 324 is a bolt.

[0050] In this embodiment, the fixed mold 10 also includes at least one pressure seat 14 mounted on the fixed mold assembly plate 11. There are two pressure seats 14. The pressure seat 14 is provided with a first inclined surface 141, and the slide seat 23 is provided with a second inclined surface 236. When the mold is closed, the pressure seat 14 moves down together with the fixed mold assembly plate 11. During the downward movement, the pressure seat 14 will push the slide seat 23 toward the moving mold core 22 until the pressure seat 14 is located between the slide seat 23 and the limit seat 34. The first inclined surface 141 abuts against the second inclined surface 236 to complete the mold closing action.

[0051] The fixed mold plate 11 includes a panel, a runner plate and an A plate 111 connected in sequence. The fixed mold core 12 and the inclined guide post 13 are both installed on the A plate 111. The fixed mold 10 is provided with a glue inlet runner, which is connected to the cavity to facilitate the injection of glue into the cavity.

[0052] The moving mold plate 21 includes a base plate, a B plate 212, and two square irons. One end of the square irons is connected to the base plate, and the other end of the square irons is connected to the B plate 212. The moving mold core 22 and the core pulling mechanism 30 are both installed on the B plate 212. The moving mold 20 can also be equipped with an ejection mechanism with the same structure as the lifting assembly 24, so as to eject and separate the product 40 from the moving mold core 22. Of course, if the quality requirements of the product 40 are not high, the ejection mechanism in the moving mold 20 can be omitted.

[0053] The working principle of the mold:

[0054] When the mold is opened, the inclined guide post 13 moves with the fixed mold plate 11 and disengages from the inclined hole 231. The inclined guide post 13 drives the slide seat 23 and the first connecting component 31 to move together towards the side of the limit seat 34 for a distance of about 15mm. The slide seat 23 disengages from the product 40, and the lifting component 24 remains stationary. At this time, the lifting component 24 protrudes from the slide seat 23 and abuts against the product 40, realizing core pulling. Under the action of its own gravity, the limit pin 33 is engaged in the slot 311. The inclined guide post 13 can drive the slide seat 23, the first connecting component 31, the second connecting component 32, the lifting component 24 and the limit pin 33 to continue moving together towards the side of the limit seat 34 for about 34mm, so that the lifting component 24 also disengages from the product 40, so as to remove the product 40.

[0055] When the mold is closed, the inclined guide post 13 is inserted into the inclined hole 231. The inclined guide post 13 drives the slide seat 23, the first connecting component 31, the second connecting component 32, the lifting component 24 and the limiting pin 33 to move about 34mm away from the limiting seat 34. After the lifting component 24 is in place, the lifting component 24 and the second connecting component 32 stop moving. The limiting pin 33 is disengaged from the slot 311 under the action of external force. The inclined guide post 13 drives the slide seat 23 and the first connecting component 31 to continue to move about 15mm away from the limiting seat 34. The slide seat 23, the fixed mold core 12, the moving mold core 22 and the lifting component 24 enclose a cavity for molding the product 40.

[0056] In summary, this utility model uses a core-pulling mechanism 30 to replace the traditional hydraulic cylinder. With the cooperation of the sliding seat 23 and the inclined guide post 13, the core-pulling mechanism 30 can drive the sliding seat 23 and the lifting assembly 24 to perform corresponding reciprocating operations, saving the cost of hydraulic cylinders, with a simple structure, optimized mold structure, and stable injection molding production, making it suitable for widespread promotion.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
