The inner rods of the four electric push rods 38 are all movable and penetrate the slide plate 31. The four electric push rods 38 are respectively aligned with the four end points of the X-connecting plate 36. The electric push rods 38 move with the slide plate 31, so they can limit or release the limit of the X-connecting plate 36. A movable mold is inserted between the inner walls of the two slots 34. Each threaded clamp 35 presses one side of the movable mold against the inner wall of the slot 34, and the inner wall of the mold chamber 2 is away from A fixed mold is installed on one side of the slide plate 31, and an adjusting mechanism 4 is provided in the mold chamber 2, including a support plate 41, one end of the support plate 41 is fixedly connected to the inner wall of the mold chamber 2, the side wall of the support plate 41 is fixedly connected to a side plate 42, the bottom of the side plate 42 is fixedly connected to a stop arm 43, and the bottom of the side plate 42 is provided with teeth 44. There are two adjusting mechanisms 4, both of which are installed in the mold chamber 2, and the teeth 44 in the two adjusting mechanisms 4 are respectively meshed with the two gears 37.

[0027] In this embodiment, the slide plate 31 is pushed by the hydraulic cylinder 7 to slide in the mold chamber 2. At the same time, the support arm 32 drives the slot 34 on the rotating rod 33 to move synchronously. The gear 37 rolls on the meshing teeth 44 and drives the slot 34 to flip 90 degrees, so that the movable mold is perpendicular to the base 1. At the same time, the gear 37 moves out of engagement, and the inner rod of the electric push rod 38 is extended to contact the four end points of the X-connecting plate 36 to always maintain the vertical limit of the movable mold.

[0028] Embodiment 2

[0029] See also Figure 1-5 On the basis of the first embodiment, the utility model provides a technical solution: preferably, a chassis 5 is installed on one side of the outer wall of the mold chamber 2, a hydraulic cylinder 7 is installed in the chassis 5, an inner rod of the hydraulic cylinder 7 passes through the chassis 5 and is fixedly connected with the slide plate 31, a storage hole 6 corresponding to the electric push rod 38 is opened on the chassis 5, and each electric push rod 38 is respectively received in the corresponding storage hole 6, a control panel 8 is installed on the other side of the outer wall of the mold chamber 2, and the control panel 8 uses numerical control program coding to control the operation of the load equipment of this case, a waste trough 9 is opened on the top of the base 1, and two guide plates 10 are symmetrically installed on the inner wall of the waste trough 9, and an air jet gun 11 is installed inside the waste trough 9, the waste trough 9 is connected to the front of the base 1 and is installed with a slot door 12, and the recycled scraps, scraps and other large-volume residues are cleaned by opening the slot door 12, and a discharge port 13 is also opened on the front of the waste trough 9, and the discharge port 13 is connected to the top of the base 1.

[0030] In this embodiment, by controlling the hydraulic cylinder 7 to retract, the slide plate 31 drives the movable mold away from the fixed mold, and the inner rod of the electric push rod 38 is retracted to release the limit on the X-connecting plate 36. The gear 37 contacts and engages with the teeth 44 on the side plate 42, and then drives the slot 34 to flip 90 degrees through the rotating rod 33, so that the movable mold is synchronously flipped 90 degrees so that the cavity faces downward, which is convenient for the air jet gun 11 to automatically clean the residue.

[0031] Working principle: the base 1 and the mold chamber 2 are used in the prior art horizontal injection molding machine, which belongs to the common horizontal injection molding machine components. The air jet gun 11 is used to spray the cavity of the movable mold, so as to blow off the large volume of residues such as scraps and scraps, so that the scraps and other residues fall into the waste trough 9. The guide plate 10 guides the scraps to roll down through its own inclined surface, which is convenient for centralized collection of the scraps, and the trough door 12 is opened later for centralized cleaning. After the cleaning is completed, the slide plate 31 is pushed by the hydraulic cylinder 7 to slide in the mold chamber 2, and the support arm 32 carries The slot 34 on the movable rotating rod 33 moves synchronously, the gear 37 rolls on the meshing teeth 44, and drives the slot 34 to flip 90 degrees, so that the movable mold is perpendicular to the base 1. At the same time, the gear 37 moves out of engagement, and the inner rod of the electric push rod 38 extends to contact the four end points of the X-connecting plate 36, so as to limit the movable mold to prevent it from shaking and flipping again during the movement process. The electric push rod 38 moves with the slide plate 31, so it can always keep the vertical limit of the movable mold, thereby prompting the movable mold to contact the fixed mold for mold closing. When the horizontal injection molding machine completes injection molding, the hydraulic The cylinder 7 contracts to drive the movable mold away from the fixed mold and stay above the discharge port 13. At this time, the material in the movable mold cavity falls off to the discharge port 13 and is discharged and recovered outside along the inner wall slope of the discharge port 13. The hydraulic cylinder 7 is controlled to contract again, causing the slide plate 31 to drive the movable mold to continue to move away from the fixed mold. When the gear 37 is suspended in front of the side plate 42, the inner rod of the electric push rod 38 is contracted to release the limit on the X-connecting plate 36, so that the hydraulic cylinder 7 is contracted again, causing the gear 37 to contact and mesh with the meshing teeth 44 on the side plate 42, and then through the rotation The rod 33 drives the slot 34 to flip 90 degrees, and the movable mold is synchronously flipped 90 degrees to make the cavity face downward, which is convenient for the jet gun 11 to automatically clean the residue. The stop arm 43 limits the gear 37 to prevent the gear 37 from excessive rotation and the slide plate 31 from excessive displacement. The threaded clamp 35 is connected to the slider by a screw rotation. The rotation of the screw causes the slider to slide on the inner wall of the slot 34, thereby clamping and fixing the movable mold. This is a relatively common technical means, so this case will not be described in detail. The threaded installation facilitates the disassembly and replacement of the movable mold.
