Description

Technical Field

[0001] The invention relates to the technical field of rubber ball production moulds, in particular to an inflatable rubber ball production and vulcanization integrated mould. Background Art

[0002] In recent years, due to the increasing shipping costs, the displacement of new ship orders placed by shipping companies has been on the rise. As the displacement of ships increases, the safety requirements of ships have also been improved, especially in terms of safety performance in ship-to-ship transfer operations or ship-to-shore transfer operations. The larger the displacement of a ship, the greater the force of wind and waves on the ship during the transfer operation. In order to absorb the impact force caused by wind and waves during the transfer operation and reduce the reaction force generated after the impact, inflatable rubber fenders (fenders) need to be placed between ships or between ships and docks. The deformation of the inflatable rubber fenders (fenders) themselves can absorb the collision energy and reduce the reaction force.

[0003] The production of inflatable rubber cushioning balls involves multiple technical links, among which the vulcanization integrated mold plays an important role in the production process. Vulcanization is a key step in rubber processing. It refers to the chemical reaction between the raw rubber in the rubber and the vulcanizing agent through heating and pressurization. The rubber is cross-linked from linear macromolecules to three-dimensional macromolecules, thus giving the rubber products the required elasticity, strength and durability.

[0004] The existing inflatable rubber ball production and vulcanization integrated mold has the problem of being unable to produce and vulcanize in the mold during use. Each demoulding process in the production process may require a lot of man-hours, reducing production efficiency and extending a single production cycle.

[0005] In summary, the prior art lacks the technology for production, vulcanization and automatic demoulding in an integrated mold for vulcanization of inflatable rubber balls. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the background technology and to propose an inflatable rubber ball production vulcanization integrated mold.

[0008] Preferably, two hydraulic rods are installed and fixedly arranged on the fixed frame in a symmetrical structure, the other ends of the hydraulic rods are connected and fixedly arranged to the movable frame, and a transmission rack is connected and fixedly arranged on one side of the movable frame.

[0009] Preferably, spiral steam pipes are installed outside the middle mold and the end mold.

[0010] Preferably, a fixed rack is connected and fixedly arranged on the fixed seat, a roller groove is opened on the fixed seat, and an inclined guide rod is connected and fixedly arranged on one side of the fixed seat.

[0011] Preferably, a transmission gear is fixedly connected to one end of the toggle frame, and the transmission gear is meshed with a transmission rack for transmission, and a driving wheel is rotatably connected to the other end of the toggle frame.

[0012] Preferably, a slide groove is provided on the movable frame, the inner wall of the slide groove is arranged in sliding contact with the outer wall of the driving wheel, and a roller foot is fixedly installed at the bottom of the movable frame, and the roller foot is arranged in sliding cooperation with the inner wall of the roller groove.

[0013] Preferably, the ball pushing mechanism includes an L-shaped frame, the bottom end of the L-shaped frame is connected and fixed to the mobile frame, one side of the upper end of the L-shaped frame is symmetrically structured and rotatably connected with two push rod groups, and a push plate is rotatably connected between the other ends of the two push rod groups, and the push plate is movably contacted with the inflatable rubber ball.

[0014] Preferably, a universal joint is rotatably provided on the L-shaped frame, a bidirectional worm is fixedly connected to the top of the universal joint, a worm wheel is fixedly connected to one end of the push rod group, the bidirectional worm and the worm wheel are meshingly transmitted, a rotating shaft is fixedly provided on the other end of the universal joint, the rotating shaft is rotatably connected to the L-shaped frame, an adjusting wheel is fixedly provided on the bottom end of the rotating shaft, and the adjusting wheel is meshingly transmitted with a fixed rack.

[0015] Preferably, the ball-supporting demoulding mechanism includes a base, one end of the base is fixedly connected to the movable frame, a ball seat is rotatably connected to the base, a limiting groove is provided on the base, a slider is slidably provided on the inner wall of the limiting groove, a connecting rod is rotatably connected to the top of the slider, the top of the connecting rod is rotatably connected to the lower surface of the ball seat, a contact wheel is rotatably connected to the lower surface of the slider, the contact wheel is movably contacted with the inclined guide rod, and a groove is provided on the ball seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has the functions of production and vulcanization in the mold, which improves the processing efficiency; 2. After the inflatable rubber ball is vulcanized by the mold, after the two end molds are separated from the middle mold, the ball push-out mechanism can automatically push the inflatable rubber ball from the middle mold to the ball seat, eliminating the need for manual demoulding, significantly shortening the production cycle, thereby improving production efficiency, enabling continuous and stable operation, reducing inconsistencies and errors caused by manual operation, and ensuring a stable production rhythm; 3. The ball demoulding mechanism can realize the automatic reception of the pushed inflatable rubber ball. When the moving frame is reset, one end of the ball seat will rotate and tilt under the action of the inclined guide rod, so that the inflatable rubber ball can fall automatically, which is convenient for it to be received again. The continuous reception and placement of the inflatable rubber ball can be realized during the production process, which further improves the efficiency of the production line, reduces manual intervention, and avoids system failure or production stagnation caused by the instability of the ball. 4. By setting a toggle rod, the toggle rod can be driven to rotate while the end mold and the middle mold are being closed and separated, so that the toggle rod will drive the moving frame to move, thereby automatically driving the ball-pushing mechanism and the ball-releasing mechanism to move to both sides of the middle mold for automatic unloading. Through the linkage design of the toggle rod and the moving frame, the automation of mold closing, separation and unloading is realized, reducing the need for manual operation, which not only reduces labor costs, but also significantly improves production efficiency and reduces human errors. Since the mold closing and separation actions are carried out simultaneously with the automatic unloading system, the operation cycle of the production line is shortened.

[0025] like Figure 6 As shown, a slide groove 701 is provided on the mobile frame 7, and the inner wall of the slide groove 701 is arranged in sliding contact with the outer wall of the driving wheel 602. A roller support foot 702 is fixedly installed at the bottom of the mobile frame 7, and the roller support foot 702 is arranged in sliding cooperation with the inner wall of the roller groove 102.

[0029] Working principle: When it is necessary to produce the inflatable rubber ball 10, first the equipment is customized according to the size of the inflatable rubber ball 10, and the inflatable rubber ball 10 is produced and formed inside the mold according to the product technical process requirements. The end flange is pre-buried during the production and forming process. After the production is completed, the external high-temperature steam enters the spiral steam pipe 301 outside the middle mold 3 and the end mold 5, and the high-temperature steam flows in the spiral steam pipe 301 to achieve heat conduction to the middle mold 3 and the end mold 5.

Then, when the contact wheel 906 contacts the inclined guide rod 103, the slider 904 connected to the contact wheel 906 will be driven to move, so that the slider 904 drives the connecting rod 905 to move, so that the connecting rod 905 drives one end of the ball seat 902 to lift up, so that the inflatable rubber ball 10 can automatically fall down, complete the demolding, and then proceed to the next processing step.
