Description

Technical Field

[0001] This utility model relates to the field of tire molding mold technology, specifically a high-efficiency heat transfer tire mold. Background Technology

[0002] A molding die is a mold made according to the shape and structure of a real object in proportion. It is a tool that uses pressing or casting methods to shape materials into a certain shape. A tire is a component that can bear the weight of a vehicle body. Cooling structures are needed in the process of using tire molding dies to improve the tire molding speed.

[0003] However, most tire forming molds still have some shortcomings. When fixing the tire forming mold, bolts are needed to fix the mold, which can easily cause the tire to deform during the forming process. At the same time, the cooling of ordinary tire forming molds is not convenient enough, and the demolding effect of the tire forming mold is not good.

[0004] Chinese Patent CN218838504U discloses a tire forming mold with a cooling function, comprising: a mounting plate with a coolant tank fixedly mounted at its lower end; a water pump fixedly connected to the left side of the mounting plate, and a cooling pipe fixedly connected to the outside of the water pump; a lower mold fixedly connected to the upper end of the mounting plate; a movable mold connected to the inner middle side of the lower mold, with a fixing plate fixedly mounted on the outside of the lower mold; a fixing component rotatably connected to the outside of the fixing plate; a cooling water pipe engaged at the upper end of the lower mold; and an upper mold fixedly connected to the upper end of a sealing ring, with cooling water pipes connected to both the inside and outside of the upper mold; an injection hole on the left surface of the upper mold; and a mounting block fixedly mounted on the lower outer side of the upper mold. This tire forming mold with a cooling function facilitates fixing and cooling of the tire forming mold, and provides good demolding effect for the tire.

[0005] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device dissipates heat from the mold through cooling water pipes, but the contact area between the cooling water pipes and the mold is limited, and the heat dissipation effect needs to be further improved. Therefore, an efficient heat transfer tire mold is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this utility model proposes a tire mold with high-efficiency heat transfer.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-efficiency heat transfer tire mold, comprising a tire mold assembly, which includes an upper mold, a lower mold, and a movable mold. The bottom end of the upper mold has a threaded groove, and the top end of the lower mold has a threaded layer fixedly connected thereto, with the threaded layer threadedly connected to the threaded groove. Cooling ports are respectively provided at the center of the upper mold and the lower mold. Sealing layers are respectively provided at the upper and lower ends of the movable mold. Sealing grooves are respectively provided on the inner walls of the upper mold and the lower mold at the locations corresponding to the sealing layers. The sealing layer is inserted into the sealing groove. The top of the upper mold has an injection port. When using this tire mold assembly, the moving mold is placed in the lower mold, and the sealing layer is inserted into the sealing groove. Then, the upper mold and the lower mold are connected through the threaded layer and the threaded groove to achieve rapid assembly of the tire mold assembly. Injection molding is performed on the inside of the tire mold assembly through the injection port. After injection molding is completed, the tire mold assembly is placed in a cooling pool. Coolant enters the moving mold through the cooling port, thereby cooling the tire mold assembly in all aspects and greatly increasing the thermal conductivity of the tire mold assembly.

[0008] Preferably, the upper mold, the lower mold, and the movable mold are arranged coaxially.

[0009] Preferably, a sealing ring is bonded inside the sealing groove to provide a waterproof seal between the sealing layer and the sealing groove, preventing cooling water from entering the tire mold assembly from the connection point.

[0010] Preferably, a limiting seat is fixedly connected to the lower inner wall of the sealing layer. The surface of the limiting seat has a limiting hole. When the moving mold is placed in the lower mold, the limiting post is aligned and inserted into the limiting hole to prevent the moving mold from rotating and affecting the tire forming effect.

[0011] Preferably, a limit post is fixedly connected to the bottom of the inner wall of the lower mold.

[0012] Preferably, the surface of the upper mold is provided with a threaded connection groove, and the threaded connection groove is coaxially arranged with the injection port. A cylinder is threadedly connected inside the threaded connection groove. When the tire mold assembly is placed in the cooling pool, the top of the cylinder must always be higher than the coolant. The detachable cylinder provides waterproof protection for the injection port, preventing coolant from entering the interior of the tire mold assembly through the injection port.

[0013] Preferably, a cooling pool is installed below the tire mold assembly, and a lifting assembly is installed on the cooling pool. The lifting assembly includes a lifting platform and two sets of electric hoists.

After injection molding, the tire mold assembly is transported to the lifting platform, and the electric hoists are used to drive the lifting platform down into the coolant. The coolant passes through the openings and completely surrounds the tire mold assembly for cooling. After cooling, the electric hoists drive the lifting platform up, and after rotating to open the upper mold and lower mold, the moving mold can automatically separate, realizing the rapid demolding of the tire.

[0014] Preferably, a U-shaped support frame is fixedly connected above the cooling pool, the electric hoist is fixedly installed on the support frame, and the chain of the electric hoist is fixedly connected to the lifting platform.

[0015] The advantages of this utility model are:

[0016] 1. This utility model places the movable mold in the lower mold and inserts the sealing layer into the sealing groove. Then, the upper mold and the lower mold are connected through the threaded layer and the threaded groove to realize the rapid assembly of the tire mold assembly. After injection molding, the tire mold assembly is placed in the cooling pool. The coolant enters the movable mold through the cooling port, thereby cooling the tire mold assembly in all aspects and greatly increasing the heat conduction efficiency of the tire mold assembly.

[0017] 2. This utility model involves transporting the tire mold assembly to a lifting platform, using an electric hoist to lower the lifting platform into the coolant. The coolant passes through the openings and completely surrounds the tire mold assembly for cooling. After cooling, the electric hoist raises the lifting platform, rotates to open the upper and lower molds, and then moves the molds to automatically separate, achieving rapid demolding of the tire.
