The first trigger component 8 includes a lifting seat 81, a sleeve 85, a touch switch 86, a spring 87, a fourth slider 88, and a second hemispherical block 89. A lifting seat 81 is slidably sleeved on the second guide rod 6. A locking mechanism for locking the lifting seat 81 on the second guide rod 6 is installed on the lifting seat 81. The position of the lifting seat 81 can be adjusted by sliding the lifting seat 81 on the second guide rod 6, so that the start of the injection molding liquid can be adjusted according to actual needs. The injection position is very convenient and flexible. The locking mechanism can lock the lifting seat 81 on the second guide rod 6. A sleeve 85 is fixed on the side of the lifting seat 81. A T-shaped columnar fourth slider 88 is connected to the sleeve 85 through a spring 87. The fourth slider 88 is slidably sleeved in the sleeve 85. A second hemispherical block 89 is fixed on the fourth slider 88. A touch switch 86 is installed inside the sleeve 85. During the core pulling process of the core pulling rod 4, when the core pulling starts, the first cavity starts to be filled with injection liquid. When the first hemispherical block 10 is connected to the second hemispherical block 89, the first cavity starts to be filled with injection liquid. When the second hemispherical block 89 on a trigger component 8 is touched, the second hemispherical block 89 compresses the spring 87 and squeezes the touch switch 86 through the fourth slider 88, thereby generating a signal, which makes it convenient to stop filling the first cavity and start filling the second cavity. Similarly, when the first hemispherical block 10 touches the second hemispherical block 89 on the second trigger component 7, a signal will also be generated, which makes it convenient to stop filling the second cavity and start filling the third cavity, thereby facilitating the batch filling of injection molding liquids of different colors.

[0021] Reference Figure 2 A first guide rod 3 is fixed on the mounting plate 2, a first slider 11 is fixed on the side of the core pulling rod 4, the first slider 11 is slidably sleeved on the first guide rod 3, the core pulling rod 4 is a hollow structure, a slide groove is provided on the side of the core pulling rod 4, a second slider 12 is fixed on the first guide rod 3, the second slider 12 is slidably installed in the slide groove, and the first slider 11 slides on the first guide rod 3 and the second slider 12 slides on the core pulling rod 4, so that the stability of the movement of the core pulling rod 4 can be improved, and the accuracy of the core pulling process can be improved.

[0022] Reference Figure 3The second guide rod 6 is provided with a scale bar 13, and the locking mechanism includes a slot 80, a screw 82, a third slider 83, and an insert block 84.

The screw 82 is rotated, and the screw 82 can be driven to move through the threaded transmission between the screw 82 and the lifting seat 81. The screw 82 pushes the third slider 83 to move, so that the insert block 84 can be inserted into the slot 80 or pulled out from the slot 80, thereby realizing the locking or unlocking of the lifting seat 81, thereby facilitating the adjustment of the position of the lifting seat 81.

[0023] Working principle: When in use, the hydraulic cylinder 1 drives the core pulling rod 4 to move through the piston rod, and the core pulling rod 4 extracts the core through the connecting piece 5.

During the core pulling process of the core pulling rod 4, when the core pulling starts, the first cavity starts to be filled with injection liquid. When the first hemispherical block 10 touches the second hemispherical block 89 on the first trigger component 8, the second hemispherical block 89 compresses the spring 87 and squeezes the touch switch 86 through the fourth slider 88, thereby generating a signal, which makes it convenient to stop filling the first cavity and start filling the second cavity. Similarly, when the first hemispherical block 10 touches the second hemispherical block 89 on the second trigger component 7, a signal is also generated, which makes it convenient to stop filling the second cavity and start filling the third cavity, thereby facilitating the batch filling of injection liquids of different colors.
