Generally, the rubber injection machine's coring column is used as a guide rod, which is mainly used to fix the product core rod so that the equipment can complete the rubber coating and remove the product from the equipment. The traditional product rack has the following disadvantages: 1. The length of the product rack body is short, and it cannot meet the fixation of extra-long products and the production needs of the equipment; 2. When the product rack body is long, such as a single-sided cantilever of 8 meters and a total length of 18 meters, there is a defect of asynchronous lifting; 3.

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 6 As shown, a synchronous lifting product rack mechanism of a rubber injection machine includes a trolley guide rail beam 1, a traction mechanism 2 and a floating support frame 3. The traction mechanism 2 includes a traction motor 21 and a wire rope 22. The traction motor 21 is arranged at both ends of the trolley guide rail beam 1. Both ends of the wire rope 22 are connected to the traction motor 21. The wire rope 22 is provided with a core rod 4 for extending into the mold cavity. The floating support frame 3 is symmetrically arranged below the trolley guide rail beam 1. The traction motor 21 drives the core rod 4 to reciprocate in the horizontal direction through the wire rope 22.

[0029] like Figure 4As shown, a movable trolley 11 is provided on the trolley guide rail beam 1, and the movable trolley 11 is positioned at both ends of the mandrel 4. The movable trolley 11 includes a crossbeam 111 and a wheel frame 112 provided at both ends of the crossbeam 111, and a roller 113 is provided on the wheel frame 112, and the roller 113 rolls on the trolley guide rail crossbeam 1, and a pressing plate 114 is provided on the crossbeam 111, and the pressing plate 114 cooperates with the crossbeam 111 to clamp the mandrel 4. During implementation, when the pressing plate 114 and the crossbeam 111 do not clamp the wire rope 22, the position of the crossbeam 111 can be manually moved, thereby changing the position of the movable trolley 11. The movable trolley 11 is used to clamp the mandrel 4, and then the mandrel 4 is sent to the forming station, that is, between the upper mold 61 and the lower mold 62 under the traction of the wire rope 22.

[0030] like Figure 2 and Figure 3 As shown, the floating support frame 3 is provided with a bracket cylinder 31 and a beam support seat 32, and the beam support seat 32 is provided with a support slide 33, which is supported at the bottom of the trolley guide rail beam 1, and the bracket cylinder 31 is connected to the beam support seat 32. The bracket cylinder 31 controls the lifting and lowering of the support slide 33 to control the height of the trolley guide rail beam 1.

[0031] The floating support frame 3 is provided with a cylinder support plate 34 which can be raised and lowered, the bracket cylinder 31 is fixed on the cylinder support plate 34, and the cross beam support seat 32 can be raised and lowered, and an adjusting screw 35 is threadedly connected to the floating support frame 3, and the top of the adjusting screw 35 is supported on the cylinder support plate 34. The adjusting screw 35 is threadedly connected to the floating support frame 3, and is used to adjust the height of the cylinder support plate 34 on the floating support frame 3, so as to adjust the height of the bracket cylinder 31. The adjusting screw 35 is rotated to realize its movement in the vertical direction relative to the floating support frame 3, so as to drive the cylinder support plate 34 to rise and fall, and control the height of the bracket cylinder 31.

[0032] like Figure 5 As shown, a mechanical demoulding frame 12 is provided below the trolley guide rail beam 1, and the mechanical demoulding frame 12 is used to limit the descending height of the trolley guide rail beam 1. Specifically, the mechanical demoulding frame 12 includes a fixed seat 121, a support seat 22 and a support rod 123. The fixed seat 121 is fixed on the trolley guide rail beam 1, and the support seat 122 is fixedly arranged. The support rod 123 passes through the support seat 122 and its top is connected to the fixed seat 121. A limiting nut 124 is provided on the support rod 123, and the limiting nut 124 abuts against the support seat 122 when the support rod 123 descends. Figure 7-10As shown, the support seat 122 is fixed on the mold base 6a. When the trolley guide rail beam 1 descends, the limit nut 124 abuts against the support seat 122, preventing the trolley guide rail beam 1 from continuing to descend, so that the trolley guide rail beam 1 does not continue to descend with the lower mold 62, so that the product and the lower mold 62 are quickly separated. Among them, the trolley guide rail beam 1 is also provided with a guide sleeve 13. During the lifting movement of the trolley guide rail beam 1, the guide sleeve 13 is movably sleeved on the coring column 63 and moves up and down along the coring column 63.

[0033] like Figure 6 As shown, the traction mechanism 2 includes a motor seat 23 disposed at both ends of the trolley guide rail beam 1, a traction motor 21 disposed on the motor seat 23, and its output shaft is connected to a winding drum 24, and both ends of the wire rope 22 are respectively wound and connected to the winding drum 24. A guide wheel 25 is provided at the end of the motor seat 23 or the trolley guide rail beam 1, and the wire rope 22 is wound around the guide wheel 25. The winding drum 24 is driven by the traction motor 21, so that the winding drum 24 is wound around the wire rope 22, driving the wire rope 22 to move in the horizontal direction on the trolley guide rail beam 1. Among them, the reciprocating motion of the wire rope 22 is realized by the cooperation of different steering directions of the traction motor 21 located at both ends of the trolley guide rail beam 1, thereby driving the movement of the moving trolley 11 and the mandrel 4.

[0034] Combination Figure 7 and Figure 8 As shown, the traction mechanism 2 moves the core rod 4 to between the upper mold 61 and the lower mold 62, and then releases the moving trolley 11 and moves the moving trolley 11 out of the mold clamping area. Then the bracket cylinder 31 and the mold clamping cylinder 64 act synchronously, and the bracket cylinder 31 pushes the beam support seat 32 up through its piston rod, and pushes the trolley guide rail beam 1 up; at the same time, the cylinder 64 pushes the lower mold 62 up, so that the lower mold 62 and the upper mold 61 are close to each other for mold clamping. When the lower mold 62 and the upper mold 61 are molded, a mold cavity is formed between them, and the core rod 4 extends into the mold cavity. After the mold is clamped, the injection molding device 5 injects the molding rubber material into the mold cavity formed by the lower mold 62 and the upper mold 61, so that the rubber is injection molded on the core rod 4. Among them, when the lower mold 62 and the upper mold 61 are molded, the plunger cylinder 65 works to pressurize and lock the mold, and the injection molding device 5 injects the rubber into the mold cavity of the mold to complete the production of the rubber product 41.

[0035] like Fig. 9As shown, after the rubber product 41 is formed on the core rod 4, the mold is separated. The plunger cylinder 65 stops pressurizing and releases the lower mold 62. Then the mold closing cylinder 64 and the bracket cylinder 31 act synchronously, the mold closing cylinder 64 drives the lower mold 62 to move downward, and the bracket cylinder 31 drives the trolley guide rail beam 1 to descend. The lower mold 62 is separated from the upper mold 61. During the descent process, when the limit nut 124 on the support rod 123 abuts against the support seat 122, the trolley guide rail beam 1 stops descending, and the mold closing cylinder 64 drives the lower mold 62 to continue to descend. When the height of the lower mold 62 is lower than the trolley guide rail beam 1, the core rod 4 and the rubber product 41 injection molded thereon are separated from the lower mold 62, achieving the effect of rapid demolding.

[0036] like Fig.10 As shown, the traction mechanism 2 is in motion, and the traction motor 21 drives the steel wire rope 22 to move horizontally. The moving trolley 11 clamps the steel wire rope 22 and is arranged at both ends of the core rod 4, and the rubber product 41 is moved out of the mold clamping area by the traction of the steel wire rope 22, so as to facilitate the transportation and lifting of the rubber product 41.
