[0023] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Example 1:

[0025] refer to Figure 1-4 A styrene-butadiene rubber molding equipment includes a base 1, a lower mold 2 is fixedly installed on the top of the base 1, a mold cavity 3 for molding the product is opened inside the lower mold 2, and a column 4 fixedly connected to the upper surface of the base 1 is provided on one side of the lower mold 2, a mounting plate 5 is fixedly installed on the top of the column 4, a hydraulic cylinder 6 is fixedly installed on the top of the mounting plate 5, the piston rod of the hydraulic cylinder 6 passes through the surface of the mounting plate 5, and a support plate 15 is fixedly connected to its lower end surface, and an upper mold 7 used in conjunction with the mold cavity 3 is fixedly installed on the bottom of the support plate 15.

[0026] refer to Figure 1 Four guide pillars 16 are fixedly connected between the base 1 and the support plate 15. The guide pillars 16 are located on the four sides of the lower mold 2. The support plate 15 slides on the surface of the guide pillars 16. When the upper mold 7 moves downward for die casting, the guide pillars 16 increase its stability and prevent the upper mold 7 from shifting.

[0027] During use, the piston rod of the hydraulic cylinder 6 drives the upper mold 7 to move downward and press it into the lower mold 2, thereby die-casting the styrene-butadiene rubber in the lower mold 2.

[0028] refer to Figure 2-3 The bottom of the mold cavity 3 is connected with a top column 9, and the top of the top column 9 is fixedly connected with a top plate 8 for ejecting the molded rubber. The top plate 8 slides inside the mold cavity, and the bottom of the top plate 8 is fixedly connected with a top block on the top of the top column 9. The upper surface of the top plate 8 is set corresponding to the molded rubber.

[0029] refer to Figure 2-3 A cavity 10 is provided inside the base 1, and a fixed plate 11 is fixedly connected to the bottom of the cavity 10. A slide groove 13 is provided at the bottom of the fixed plate 11 for the ejector column 9 to slide, which is used to improve the stability of the ejection molding rubber. The middle part of the ejector column 9 is fixedly connected to a pressure plate 111 that slides inside the cavity 10. A spring 12 is fixedly connected between the pressure plate 111 and the fixed plate 11. The ejector column 9 passes through the inside of the spring 12, and a groove 14 corresponding to the ejector plate 8 is provided at the bottom of the mold cavity 3.

[0030] Furthermore, when the upper mold 7 is not performing die-casting, the top plate 8 is located above the groove 14. When the upper mold 7 is performing die-casting, the upper mold 7 presses the rubber and thereby presses the top plate 8 downward. After the rubber is molded, the upper mold 7 is moved out, and the spring 12 drives the top column 9 to move upward, thereby causing the top plate 8 to move upward and eject the molded rubber, facilitating demoulding and accelerating work efficiency.

[0031] Furthermore, when the rubber is die-cast, the molten rubber is poured into the mold cavity 3 and located on the upper surface of the top plate 8. The output end of the hydraulic cylinder 6 drives the upper mold 7 to move downward, and the guide column 16 maintains its stability. The upper mold 7 presses the rubber and thereby presses the top plate 8 downward. The upper mold 7 is pressed into the mold cavity 3 and remains stationary. After the rubber is molded, the upper mold 7 is moved out, and the spring 12 drives the top column 9 to move upward, thereby causing the top plate 8 to move upward to eject the molded rubber, so that the rubber is separated from the mold cavity, making it easier for the staff to remove it.

[0032] Example 2:

[0033] refer to Figure 1 、 2 , 5 and 6, a cooling plate 17 is fixedly connected to the bottom of the upper mold 7, and the cooling plate 17 is arranged corresponding to the molding rubber and is used to cool the upper surface of the rubber. A cooling groove 18 is opened inside the cooling plate 17, and the cooling groove 18 is arranged in a "snake" shape. One end of the cooling groove 18 is connected with a water inlet pipe 19 running through one side of the upper mold 7 for passing cooling water, and the other end of the cooling groove 18 is connected with a water outlet pipe 20 running through the other side of the upper mold 7 for discharging cooled water. The cooling water circulation arrangement improves the use effect.

[0034] refer to Figure 1-2 A cooling bin 21 is provided inside the lower mold 2 and outside the mold cavity 3. The cooling bin 21 is in a "U" shape and is hollow. Air ducts 22 are connected on both sides of the cooling bin 21. A fan 23 is provided at one end of the air duct 22 to dissipate the heat inside the cooling bin 21 and speed up the cooling speed. Air inlets 24 are provided on the front and rear sides of the lower mold 2. The air inlets 24 are connected to the cooling bin 21 for internal air circulation.

[0035] Furthermore, after the rubber is pressed, the water inlet pipe 19 is controlled to input cooling water and the fan 23 is rotated at the same time. The fan 23 cooperates with the air inlet 24 to accelerate the air flow rate in the cooling chamber 21 and accelerate the heat dissipation. After the cooling water enters the cooling groove 18, the upper surface of the rubber is cooled. The air cooling and water cooling are used in combination to accelerate the cooling speed and improve work efficiency. The cooled water is discharged from the water outlet pipe 20 for easy use next time.
