[0002] Raw rubber is softened by heat, hardened and brittle when cold, not easy to form, easy to wear, and soluble in organic solvents such as gasoline. In order to improve the performance of rubber products, the raw rubber in the rubber compound is chemically reacted with a vulcanizing agent, so that it is crosslinked from a linear structure macromolecule into a three-dimensional network structure macromolecule, thereby making the rubber compound have excellent properties such as high strength, high elasticity, high wear resistance, corrosion resistance and the like. The traditional method is to vulcanize the rubber compound by using steam or far infrared heating.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a rubber vulcanization molding apparatus, such as... Figures 1-5 As shown, the molding device includes a rubber vulcanizing molding machine 1 and a hydraulic cylinder 11 installed on the rubber vulcanizing molding machine 1. A control host 2 is provided on one side of the rubber vulcanizing molding machine 1. A guide rail frame 4 and a mold plate 12 slidably installed on the guide rail frame 4 are provided on the rubber vulcanizing molding machine 1.

[0025] The rubber vulcanizing molding machine 1 is equipped with a demolding mechanism 6;

[0026] The demolding mechanism 6 comprises a support table 5 connected with the rubber vulcanization molding machine 1 and a refrigeration assembly 66 symmetrically installed on the support table 5, the upper end of the support table 5 is provided with a second air cylinder 65, the telescopic end of the second air cylinder 65 is connected with a support frame 651, the upper end of the support frame 651 is provided with a demolding plate 61, a plurality of demolding columns 62 are equidistantly installed on the demolding plate 61, the number of the demolding columns 62 is equal to that of the mold holes on the demolding plate 61, the lower end of the demolding plate 61 is provided with a wind distribution pipe 63 connected with the demolding columns 62, and the air outlet of the refrigeration assembly 66 is connected with the wind distribution pipe 63.

[0027] Specifically, when the second air cylinder 65 is started, the demolding plate 61 is driven to move upward, and the material on the mold plate 12 is pushed out by the demolding columns 62. In the process of pushing out the material, the refrigeration assembly 66 is started to generate cold air, and the cold air is introduced into the lower side of the demolding plate 61 through the air guide cavities 622 of the demolding columns 62. The cold air can cool the material and the mold plate 12 at the same time, so that the rubber product can be quickly shrunk during demolding, the demolding difficulty is reduced, the possibility of product damage is reduced, the temperature of the mold plate 12 is reduced, and the service life of the mold is prolonged.

[0028] The demolding columns 62 are internally provided with air guide cavities 622, and the demolding columns 62 are fixedly provided with isolation net rings 621.

[0029] More specifically, the air guide cavities 622 in the demolding columns 62 are used for the circulation of cold air, the isolation net rings 621 are fixed on the demolding columns 62, and the isolation net rings 621 prevent sundries from entering the air guide cavities 622 to affect the circulation of cold air.

[0030] A plurality of air guide pipes 623 connected with the bottoms of the demolding columns 62 are equidistantly installed on the wind distribution pipe 63, both ends of the wind distribution pipe 63 are provided with air connection ports 631, and the hoses 661 on the refrigeration assembly 66 are connected with the air connection ports 631.

[0031] Further, the refrigeration assembly 66 adopts a compressor refrigeration system, which comprises a compressor, a condenser, an evaporator and a throttling device, etc. The compressor compresses the refrigerant into high-temperature and high-pressure gas, which enters the condenser to be cooled into high-pressure liquid. After being reduced in pressure by the throttling device, the high-pressure liquid enters the evaporator to be evaporated into low-temperature and low-pressure gas by absorbing heat, and then returns to the compressor for circulation. The evaporator exchanges heat with air to cool the air, and the generated cold air is delivered to the wind distribution pipe 63 through the air outlet. The cold air generated by the refrigeration assembly 66 is delivered to the air connection ports 631 of the wind distribution pipe 63 through the hoses 661. The wind distribution pipe 63 distributes the cold air to the air guide cavities 622 of the demolding columns 62 through the air guide pipes 623, so that the material and the mold at each mold hole can be uniformly cooled, the product quality difference caused by uneven cooling is avoided, the consistency and quality stability of the product are improved, and the hoses 661 can effectively adapt to the up-and-down movement of the wind distribution pipe 63 without limitation.

[0032] A plurality of fixing plates 64 are symmetrically arranged on the stripping plate 61 and sleeved with the air distribution pipe 63.

[0033] Further, the fixing plates 64 are symmetrically arranged on the stripping plate 61 and sleeved with the air distribution pipe 63, which can fix the air distribution pipe 63. The stable air distribution pipe 63 can ensure the normal delivery and distribution of cold air, avoid the poor delivery or uneven distribution of cold air caused by the shaking of the air distribution pipe 63, and further improve the cooling effect and stripping quality.

[0034] The fixing plates 64 are fixedly connected with the stripping plate 61 through bolts, and the support table 5 is symmetrically provided with a connecting plate 67 intersecting with the rubber vulcanization molding machine 1, which is fixedly connected with the rubber vulcanization molding machine 1 through bolts.

[0035] It should be noted that the fixing plates 64 are fixedly connected with the stripping plate 61 through bolts to ensure the fixing effect of the fixing plates 64 on the air distribution pipe 63, and the connecting plate 67 connects the support table 5 and the rubber vulcanization molding machine 1 together through bolts, so that the stripping mechanism 6 and the rubber vulcanization molding machine 1 form a stable whole.

[0036] The rubber vulcanization molding machine 1 is fixedly provided with an assembly plate on the side away from the support table 5, the assembly plate is provided with the first cylinder 3, and the telescopic end of the first cylinder 3 is fixedly connected with one side of the mold plate 12.

[0037] It is worth mentioning that the first cylinder 3 is installed on the assembly plate on the side of the rubber vulcanization molding machine 1 away from the support table 5, and the telescopic end thereof is connected with the mold plate 12, which is driven to move along the guide rail frame 4 through the telescopic action of the first cylinder 3.

[0038] In use, the guide rail frame 4 plays a role in guiding the linear movement of the mold plate 12. When the mold plate 12 moves to the farthest end along the guide rail frame 4, the mold plate 12 is directly above the stripping plate 61, and the stripping columns 62 at the upper end of the stripping plate 61 are respectively aligned with the mold holes on the mold plate 12. When the second cylinder 65 is started, it drives the stripping plate 61 to move upward, and the stripping columns 62 push out the material on the mold plate 12. In the process of pushing out the material, the refrigeration assembly 66 is started to generate cold air, which is introduced into the lower side of the stripping plate 61 through the air guide cavities 622 of the stripping columns 62, so as to cool the material and the mold plate 12.

[0039] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this.
