The hydraulic system 1-1 and the main pressure oil cylinder constitute a hydraulic jacking mechanism, and the hydraulic jacking mechanism also comprises a jacking pressure plate 1-3, wherein the main pressure oil cylinder is a jacking oil cylinder 1-2. The jacking pressure plate 1-3 corresponds to the mold level at the head end, is hoisted on the track through the mold pulley mechanism, and moves horizontally with the telescopic movement of the jacking oil cylinder. The unified axial pressing of each mold combination is realized. A track 7 is arranged inside the main frame 3, and the two tracks are arranged horizontally and side by side. A belt 9 and a pneumatic die drawing mechanism 2 used in conjunction with the belt 9 are arranged above the track 7, and the mold pulley mechanism 6 is slidably matched with the track 7, and moves synchronously with the belt 9 through the belt pressing mechanism 8.

[0027] As a preferred embodiment, the pneumatic die drawing mechanism includes a die drawing cylinder 2-1, a main mounting frame 2-3 and a sub-mounting frame 2-4. The two main mounting frames 2-3 are respectively mounted on the inner walls on both sides of the frame, and a static pulley group 2-7 is arranged on the inner side of the main mounting frame. The sub-mounting frame 2-4 is hoisted in the middle of the horizontal direction of the main frame. The die drawing cylinder 2-1 is hoisted between the sub-mounting frame 2-4 and the main mounting frame 2-3 at the head end through the cylinder hoisting frame 2-2. In this embodiment, the side close to the hydraulic tightening mechanism is the head end. The die drawing cylinder 2-1 is a double-axis double-acting cylinder, and movable pulleys 2-8 are installed on the protruding ends on both sides. After the two ends of the belt 9 are respectively wound around the static pulley group and the movable pulley, they are connected to the sub-mounting frame 2-4 and the main mounting frame 2-3 respectively.

[0028] See Figure 5 and 9 The specific structure is as follows: a connecting plate 2-6 is provided on the main mounting frame 2-3 near the side (head end) of the die cylinder 2-1, and the free end of the belt 9 on this side passes through the static pulley group 2-7 from bottom to top, then turns back horizontally, passes through the movable pulley 2-8 at the telescopic end of the die cylinder on this side, then turns back horizontally and is fixed on the connecting plate 2-6. The other free end of the belt 9 passes through the static pulley group 2-7 on the main frame away from the side (tail end) of the die cylinder 2-1 from bottom to top, turns back horizontally, passes through the auxiliary frame 2-5, passes through the movable pulley 2-8 at the telescopic end of the die cylinder 2-1 on this side, then turns back horizontally and is fixed on the auxiliary mounting frame 2-4.

[0029] Preferably, the pneumatic die drawing mechanism also includes an auxiliary frame 2-5, and multiple auxiliary frames are evenly arranged on the frame on the side away from the die drawing cylinder. Rollers are movably installed on the auxiliary frame 2-5, and the belt 9 passes through the center of the auxiliary frame 2-5 and slides with the rollers.

[0030] The pneumatic die drawing mechanism adopts a double-axis compound cylinder to achieve double-stroke die opening and closing control through a pulley, and meets the large blank removal space, which increases safety.

[0031] In another preferred embodiment, the mold pulley mechanism 6 cooperates with the mold combination, including a pulley roller, a hanging mold frame 6-2 and a belt clamping mechanism 8. The pulley roller is arranged between two tracks, and the belt passes through the gap between the pulley roller and the hanging mold frame. The pulley roller includes pulleys 6-3 on both sides and a roller body 6-1 in the middle. The pulleys 6-3 on both sides of the pulley roller are overlapped on the tracks 7 on both sides, the upper part of the hanging mold frame 6-2 is a hook body, which is hung on the roller body 6-1, and the belt clamping mechanism 8 is installed on the hanging mold frame 6-2. At least two mold combinations are arranged on the axial track 7 of the forming machine. Disclosed in this embodiment is a ring mold combination and a body mold combination of a toilet. The mold combinations are all hoisted by the mold pulley mechanism 6.

[0032] Preferably, the belt clamping mechanism 8 includes a clamping cylinder 8-1, a clamping plate 8-2 and a limiting frame 8-3. The limiting frame 8-3 is a frame structure, and the side plates on both sides thereof are installed on the sides of the hanging mold frame 6-2 through bolts and other connecting parts. The clamping cylinder 8-1 is installed on the hanging mold frame 6-2 below the limiting frame 8-3, and the clamping plate 8-2 is installed on the protruding end of the clamping cylinder 8-1, and the clamping plate is placed in the frame structure of the limiting frame. The protruding end of the clamping cylinder 8-1 is extended and retracted while realizing the up and down movement of the clamping plate, thereby realizing the clamping and loosening of the belt inserted between the clamping plate and the limiting frame. The gap between the clamping plate and the upper part of the limiting frame corresponds to the gap between the hanging mold frame and the roller body.

[0033] The clamping cylinder 8-1 and the die-drawing cylinder 2-1 are both connected to the air control system, and precise individual control is achieved through PLC. Each group of molds is independently equipped with a mold opening and closing drive unit, and is connected to the air control system. Different mold combinations have different devices for controlling clamping. For example, the body mold combination has a side clamping device in addition to the axial clamping and closing. Each mold group is independently equipped with a side clamping device, and is connected to the air control system. The present invention is also equipped with a grouting system, which is arranged on the outside of the main frame and cooperates independently with each mold group.

[0034] The working process of the present invention is as follows: Initial state: the die drawing cylinder is in the retracted state, the belt pressing cylinder is in the retracted state, the side opening and closing cylinder is in the extended state, the ring model is in the open state, the main pressure cylinder is in the retracted state, and the operating program enters the standby initial state.

[0035] Grouting molding: After the air control system starts the control equipment, the molding machine executes the model merging program, the main pressure cylinder extends and presses the mold close to it to achieve axial compression of the mold, and at the same time controls the side compression cylinder of the body mold group in the mold combination to compress. The mud is pressurized and injected into the mold cavity through the grouting system.

[0036] Ring model demolding: After the grouting molding is completed, the PLC controls the main oil cylinder to retract, and the air control system controls the first station ring mold demolding through the PLC. At the same time, the corresponding station belt pressing cylinder extends and the film pulling cylinder retracts to drive the first station ring die to move to the specified position. The concave and convex molds of the ring mold are separated, and the belt pressing cylinder retracts. The blank is adsorbed on the convex mold under the action of vacuum, and the convex mold demolding control valve group is opened manually or automatically. At this time, the blank is taken manually or by robot, and the action cycle of the first station of the ring is completed; When the blank is taken at the previous station, the main cylinder of the die drawing device retracts to the initial position, and the concave and convex dies of the ring mold of the subsequent station are separated through the belt and the belt clamping device, and the instructions of the previous process are repeated to complete the demolding and receiving of the ring blank at this station. One action cycle of the second station is completed. The subsequent action cycle is the same as the second station.

[0037] Body model demolding: After all the ring blanks are demolded and taken out, the PLC controls the main cylinder to retract, and the PLC controls the demolding of the front model of the first station body mold. At the same time, the belt pressing cylinder of the corresponding station of the body extends and the film drawing cylinder retracts to drive the front mold of the first station to move to the specified position, and the belt pressing cylinder of this station retracts. The body side mold pressing cylinder is loosened and retracted, and at the same time, the main cylinder of the die drawing device retracts to the initial position. The PLC controls the demolding action of the left and right models of the body to start, and the blank is adsorbed on the rear model of the body under the action of vacuum. The body side mold opening and closing cylinder retracts, and the left and right molds of the body are separated through the auxiliary mechanism, and the belt pressing cylinders of the left and right side molds of the body extend. The main cylinder of the die drawing device extends, and the PLC sets the time point to control the body side mold opening and closing cylinder to extend, so that the left and right side molds of the body are completely merged before contact with the front model of the body. The blank on the rear model is opened manually or automatically to control the rear mold demoulding control valve group. At this time, the blank is taken manually or by robot, and the action cycle of the first station of the body is completed; the subsequent action cycle is the same as the second station.

[0038] The present invention changes the production form of traditional toilet bowls and uses a horizontal structure to achieve this, thereby eliminating the flipping and tilting actions in traditional equipment, greatly reducing the equipment materials and the overall space occupied by the equipment. The open design of the hoisting mold meets the mixed production of products of multiple specifications, greatly improves the diversity of the equipment, and can quickly meet the needs of different products on the market. It greatly reduces the amount of manual labor and achieves safe and efficient production.
