[0035] Specific embodiments of the utility model:

[0036] See attached Figure 1 , 2 , 7 and 8, the longitudinal slide rail mechanism 3 and the transverse slide rail mechanism 4 are arranged in an upper and lower stacking manner to form a double double slide rail driving structure, and the sliding cooperation and limit function are realized by the limit slider and the slide rail, so as to realize the longitudinal displacement and transverse displacement of the injection head. The top of the transverse slide rail mechanism 4 is equipped with a sandwich rotary reducer through a flange, and a worm gear structure is adopted to realize self-locking angle control, and the reduction ratio is large, so as to ensure accurate control of the injection head rotation.

[0037] The longitudinal slide rail mechanism 3 includes a T-shaped slide rail 301, a double-slide rail bridge 302 and an L-shaped limit block 303. The T-shaped slide rail 301 is a single long T-shaped structure, the top surface of which serves as a bearing surface, and the lower bottom surface is welded to the upper crossbeam 7 on the top of the embedded tower frame. The lower wing surfaces on both sides of the T-shaped slide rail 301 are inclined as limit surfaces, and the limit sliders 3021 on both sides of the double-slide rail bridge 302 are provided with inner grooves, which match the T-shaped slide rail 301. An L-shaped limit block 3025 is assembled on the outer side of the limit slider 3021 to limit the degree of freedom, and only the longitudinal displacement is retained.

[0038] The double-slide rail driving bridge 302 is composed of a limit slider 3021, a driving bridge 3022, a high-position crossbeam 3023, an I-shaped slide rail 3024 and an L-shaped limit block 3025. There are two I-shaped slide rails 3024, which are arranged in parallel with each other. The two I-shaped slide rails 3024 are vertically arranged between the upper crossbeam 7. The bottoms of the two I-shaped slide rails 3024 are welded to the top of the driving bridge 3022. The driving bridge 3022 is composed of two webs with process holes, which are in an inverted trapezoidal shape, and steel plates are welded on the upper and lower surfaces. Two high-position crossbeams 3023 are arranged in parallel above the upper crossbeam 7, and the two ends of the two high-position crossbeams 3023 are respectively connected to the two ends of the two I-shaped slide rails 3024 to form a rectangular frame. The outer side of the limit slider 3021 is reserved with tapping holes, which can be fixed with the L-shaped limit block 3025 by bolts. There are four limit sliders 3021 distributed on the four corners of the rectangular frame. The top of the limit slider 3021 is welded to the end of the high beam 3023 and the I-shaped slide rail 3024. The high beam 3023 is made by cutting a square tube, and the cutting notch is consistent with the size of the I-shaped slide rail 3024.

[0039] The transverse slide rail mechanism 4 is installed on the top of the double slide rail axle 302, and is mainly composed of a one-way limit slider 401, a double bridge frame 402, a top plate 403, a side vertical plate 404, a lower flange 405 and an L-shaped limit block 406. A single-sided notch is opened inside the one-way limit slider 401, and the groove shape is the same as that on one side of the I-shaped slide rail 3024. The single-sided notches of each one-way limit slider have the same opening direction, so that the transverse slide rail mechanism 4 can be pushed into the grooves on one side of the two I-shaped slide rails 3024 from one side. An L-shaped limit block 406 or an L-shaped limit claw can be installed at the opening of the one-way limit slider 401 to prevent the transverse slide rail mechanism 4 from detaching.

[0040] The double bridge frame 402 is made of perforated steel plates assembled and welded, and is similar to the structure of the driving bridge 3022. A square top plate 403 is welded on the top. The top plate 403 has a hole in the middle, and the hole diameter is consistent with the outer diameter of the lower flange 405, which is connected by welding. The side plate 404 is welded to the outside of the double bridge frame 402 and the top plate 403, forming the transverse slide mechanism 4 into an overall rectangle. The lower flange 405 is a transition cone with a large bottom diameter and a small top diameter. The flange mounting hole is integrally processed, and the flange mounting size is the same as that of the sandwich rotary reducer 5.

[0041] The oil cylinder 2 is installed in the traveling bridge 3022 of the double-slide-rail traveling bridge 302, and the lever of the oil cylinder 2 is connected to the double bridge frame 402.

[0042] The sandwich rotary reducer 5 is a well-known and commonly used device in the art, and adopts a worm gear reducer, with the worm as the active end, driven by a hydraulic motor 501, and can withstand top loads and large overturning moments. The sandwich rotary reducer 5 is installed between the lower flange and the upper flange of the injection head mounting seat, and the upper and lower mounting surfaces of the sandwich rotary reducer 5 are both flange surfaces, which are fixed by long bolts and nuts.

[0043] The injection head mounting seat 6 is used to install and carry the injection head load and operating load, and is composed of an upper flange 601, a base frame 602, a transition plate 603, a reinforcing rib 604, a fixed pin seat 605 and an injection head pin 606. The upper flange 601 is welded to the bottom of the lowest point of the injection head mounting seat 6, and is connected to the flange bolts of the sandwich rotary reducer 5, and the base frame 602 is raised to avoid interference with the reducer or motor. The base frame 602 is made of profile welding and is an unequal octagon, and a transition plate 603 is welded at the center. The transition plate 603 has an inner hole, and the inner hole has the same outer diameter as the upper flange 601, and is welded and fused to reduce the flange processing amount. The reinforcing rib 604 is welded on the transition plate 603 in the inner groove of the base frame 602 to form a triangular support to enhance the structural strength. The fixed pin seat 605 is a double-plate structure with through holes from top to bottom. The through hole positioning size is the same as the injection head positioning pin sleeve. Multiple through holes match different injection heads. The outermost end is welded with a reinforced cylindrical sleeve between the double plates. The injection head pin 606 is installed on the fixed pin seat 605. The injection head pin 606 can be rotated arbitrarily to adapt to the direction of the injection head positioning pin sleeve. The bottom is locked by a gasket, a cotter pin and a slotted nut. The size and structure of the injection head pin 606 can be replaced arbitrarily.

[0044] The oil cylinder 1 can be a threaded locking oil cylinder, whose cylinder rod is provided with threads, and can bear a unidirectional locking force through a locking nut. After locking, it is not affected by the hydraulic system, which meets the working conditions of the injection head being subjected to a single-direction overturning force. The oil cylinder 2 can be a limit oil cylinder to control the displacement, ensuring that it can be limited at any position during operation. The sandwich rotary reducer is driven by a hydraulic motor, and can achieve operation at any angle through the self-locking ability of the turbine and worm, and because the reduction ratio of the turbine and worm is large, the angle can be fine-tuned.
