Description

Technical Field

[0001] This utility model relates to the technical field of vulcanizing molds, and in particular to a novel vulcanizing mold. Background Technology

[0002] In traditional rubber vulcanization mold processes, external equipment is typically used to heat the mold, and the heat is conducted to vulcanize the rubber within the mold cavity. However, this method has significant limitations in applications requiring bonding between rubber and ultra-high molecular weight polyethylene (UHMWPE). Since UHMWPE has a fixed softening temperature, the key to achieving a strong bond between it and rubber lies in precisely controlling the mold cavity temperature, keeping the UHMWPE in a critical state where it begins to melt but is not completely liquid, followed by rapid cooling. This process ensures that the UHMWPE maintains the mold cavity shape after cooling and forms a stable bonding interface with the rubber.

[0003] The currently used ultra-high molecular weight polyethylene (UHMWPE) has a molecular weight of 8 million and a softening temperature of 135℃. Therefore, the mold cavity temperature must be strictly controlled within the range of 135℃–139℃. If the temperature is too high, the UHMWPE will over-melt, resulting in a rough product surface and severe deformation of the bonding interface after cooling; if the temperature is too low, effective bonding cannot be achieved. Furthermore, to ensure product consistency, the temperature distribution of each mold cavity must be uniform. If there are temperature differences between mold cavities, it will cause quality problems such as weak bonding or deformation of some products, making it difficult to achieve the same process state for all products within the specified bonding time. Existing methods relying on equipment heating cannot achieve such precise temperature control and cannot simultaneously meet the process requirements of rapid heating and cooling. Therefore, a new temperature control method is urgently needed to solve this technical challenge. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel vulcanizing mold.

[0005] This utility model discloses a novel vulcanizing mold, comprising a mold body and mold cavities. The mold body has two sets of mold cavities, and the interior of the mold body has two sets of hot oil channels and two sets of cold water channels. It also includes a heating component and a cooling component. The heating component supplies hot oil to the two sets of hot oil channels, and the cooling component supplies cold water to the two sets of cold water channels. In use, the heating component allows hot oil to enter the two sets of hot oil channels to heat the mold body. Once the set temperature is reached, rubber and ultra-high molecular weight polyethylene are placed inside the mold cavities. The mold is closed, and the bonding temperature is set. After the bonding temperature is reached, the cooling component is turned on while the heating component continues to run, cooling the mold body. After the set cooling time is reached, the cooling component is turned off, while the heating component continues to run. The mold is then opened, the bonded product inside the mold cavity is removed, and new rubber and ultra-high molecular weight polyethylene are placed inside. The continuous operation of the heating component allows for rapid heating of the mold body, reducing heating time and improving heating efficiency.

[0006] Preferably, the heating assembly includes a mold temperature controller, an oil inlet pipe, an oil return pipe, an oil inlet valve, and an oil return valve. The output end of the mold temperature controller is connected to the input end of a No. 1 A tee pipe. The two sets of output ends of the No. 1 A tee pipe are respectively connected to the input ends of two sets of oil inlet pipes. The output ends of the two sets of oil inlet pipes are respectively connected to the input end of a set of hot oil channels. Each set of oil inlet pipes is equipped with an oil inlet valve. The output ends of the two sets of hot oil channels are respectively connected to the input end of a set of oil return pipes. The output ends of the two sets of oil return pipes are both connected to the two sets of input ends of a No. 1 B tee pipe. The output end of the No. 1 B tee pipe is connected to the input end of the mold temperature controller. Each set of oil return pipes is equipped with an oil return valve. When the mold temperature controller is started, it heats and delivers kerosene. By adjusting the opening and closing degree of the oil inlet valve and the oil return valve, the flow rate of hot kerosene in the hot oil channel is adjusted, thereby improving the heating efficiency of the rubber and ultra-high molecular weight polyethylene inside the mold cavity.

[0007] Preferably, the cooling assembly includes a cooler, an inlet pipe, a return pipe, an inlet valve, and a return valve. The output end of the cooler is connected to the input end of the No. 2A tee pipe. The two sets of output ends of the No. 2A tee pipe are each connected to the input end of one set of inlet pipes. The output end of each set of inlet pipes is connected to the input end of one set of cold water channels. The output end of each set of cold water channels is connected to the input end of one set of return pipes. The output ends of both sets of return pipes are connected to the two sets of input ends of the No. 2B tee pipe. The output end of the No. 2B tee pipe is connected to the input end of the cooler. Each set of inlet pipes is equipped with an inlet valve, and each set of return pipes is equipped with a return valve. When it is necessary to cool the mold cavity inside the mold body, the cooler is started, so that the cooler cools and delivers the water. The cooling water enters the cold water channel through the inlet pipe to cool the mold body and then returns to the cooler through the return pipe for further cooling. The operator adjusts the flow rate of the cooling water in the cold water channel through the inlet valve and the return valve to improve operational flexibility.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the heating component allows hot oil to enter two sets of hot oil channels to heat the mold body. After the temperature reaches the set temperature, rubber and ultra-high molecular weight polyethylene are placed inside the mold cavity, the mold is closed, the bonding temperature is set, and after the bonding temperature is reached, the cooling component is turned on while the heating component continues to run. The cooling component cools the mold body. After the set cooling time is reached, the cooling component is turned off while the heating component continues to run. The mold is opened, the bonded product inside the mold cavity is taken out, and new rubber products and ultra-high molecular weight polyethylene are placed in. The continuous operation of the heating component can quickly heat the mold body, reduce the heating time of the mold body, and improve the heating efficiency. Attached Figure Description
