Description

Inflatable wheel infusion forming device

This creation is about a wheel manufacturing technology, especially a non-inflatable wheel infusion forming device.

Know the wheels of automobiles, including the wheels of cars for general automobiles, the wheels of recreational vehicles, the wheels of large trucks, the wheels of engineering vehicles, the wheels of agricultural vehicles, and of course the wheels of organic vehicles and bicycle wheels. There are many types of wheels, and most of these wheels are currently composed of tires mounted on the wheel frame (traditional wheels include tires and inner tubes). The tires are inflated to inflate the tires to support the vehicle. It is on the ground and rolls when driven to allow the vehicle to travel on the road.

However, in addition to such conventional inflatable vehicle wheels, in addition to paying attention to whether the tire pressure is maintained at normal pressure (for example, the wheel of a car is about 30psi), it also often occurs that the wheel is nailed and glass during travel. Or some sharp objects are punctured, and the wheels are discouraged by the hole at this time. If the vehicle is broken down, if you have experience in wheel replacement, you can bring your own tools to replace the spare tire or request road rescue; but if the wheels are at high speed The marching process was punctured, at this time there was a danger of a flat tire, which could cause regrets. It can be seen that although the conventional inflatable vehicle wheels are still widely used at present, there are still problems such as tire pressure control and rupture and failure in use. Therefore, how to solve these problems is based on The point of creation is.

In order to solve the above-mentioned problems, the present invention provides a non-inflatable wheel infusion molding device, which can be made into an inflatable wheel to be installed on a vehicle instead of the conventional conventional inflatable vehicle wheel.

An embodiment of the present invention provides an inflatable wheel infusion forming device. The wheel includes an outer ring, a spoke, and an inner ring.

The following describes the infusion molding process 300 of the above-mentioned non-inflatable wheel infusion molding apparatus 100, as shown in FIG. 5, including a mold pressure fixing step 301, a pouring rubber step 302, a vulcanization setting step 303, and a finished product demoulding step 304, among which:

In the mold pressure fixing step 301, the outer cover 20 is provided on the outer periphery 12 of the inner mold 10, and the middle seat 30 is provided on the middle hole 13 of the inner mold 10 to form a communicating outer circulation channel 22, The spoke runner 11 and the inner annular runner 32 fix the assembled inner mold 10, the outer cover 20 and the middle seat 30 on the platform 61, and align the runner 15 with the injection channel 62 on the platform 61. As shown in FIG. 6, the first die plate 40 in this embodiment has two first bumps 44. The two first bumps 44 extend horizontally on opposite sides of the first die plate 40. When the die plate 40 is placed on the platform 61, the first protrusion 44 can be positioned by being clamped by the clamp 63 and the platform 61, so that the first die plate 40 is fixed on the platform 61 without moving; and the outer cover 20 of this embodiment It has two second bumps 23, which are located on opposite sides of the cover 20 and also extend horizontally. The two second bumps 23 and the two first bumps 44 can be aligned with each other, and During the alignment, the pins 45 are positioned next to each other so that the outer cover 20 and the inner mold 10 will not be displaced.

In the filling compound step 302, a pressurizing unit 70 is connected to the sprue 62 through a pipeline 71 (as shown in FIG. 7). The pressurizing unit 70 passes the rubber from the sprue 62 to the runner 15 and The outer circulation channel 22, the spoke flow channel 11 and the inner circulation channel 32 are filled and filled. In this embodiment, a cross bar 24 is provided on the top of the outer cover 20, and the second bar 50 is pressed by the cross bar 24 (as shown in FIG. 6), thereby positioning the inner mold 10 in the outer cover 20. To avoid the relative displacement of the inner mold 10 and the outer cover 20 caused by the force generated by the pressurizing unit 70 pouring the rubber. In this embodiment, in the step 302 of filling the rubber compound, a vacuum pumping unit 80 is used to perform a vacuum pumping action on the outer circulation channel 22, the spoke flow channel 11 and the inner circulation channel 32. At this time, the vacuum pumping unit 80 is connected to the seal by a pipe 81. At the sealing sleeve 82 (as shown in FIG. 7) on the top of the injection molding device 100, while filling the rubber material, the air in the outer ring runner 22, the spoke runner 11 and the inner ring runner 32 is evacuated to make the finished product. There is no air remaining on the outer ring 201, the spokes 202, and the inner ring 203 of the wheel 200, so no air bubbles are generated. In this embodiment, the pressurizing unit 70 is a hydraulic cylinder driven by oil pressure, and the vacuuming unit 80 is a vacuum pump.

In the vulcanization and setting step 303, a heating unit (not shown) is provided for the inner mold 10, the outer cover 20, and the middle seat 30 provided on the platform 61 after the assembly, so that the heating unit described above fills the foregoing. The rubber compounds in the outer circulation channel 22, the spoke flow channel 11 and the inner circulation channel 32 are heated to vulcanize the rubber in the communicating outer circulation channel 22, the spoke flow channel 11 and the inner circulation channel 32, and cool after the vulcanization is completed. While shaping the wheel 200. In this embodiment, the heating unit is a baking box as an example. That is, the assembled inner mold 10, the outer cover 20, and the middle seat 30 enter the baking box on the platform 61 with the provided base 60. A heating operation is performed during the heating, but is not limited thereto. A heating element (such as an electric heating tube or a heating sheet) may be installed in the inner mold 10, the outer cover 20, and / or the middle seat 30, and the heating operation may also be performed.

In the finished product demolding step 304, as shown in FIG. 8, the outer cover 20 and the middle seat 30 are separated from the inner mold 10, and the shaped wheel 200 is removed from the inner mold 10 to make the wheel 200. In a preferred embodiment, the cross bar 24 is removed so that the outer cover 20 can be detached from the inner mold 10. At this time, a hanger (such as a sling) can be used to hook the outer cover 20 and the outer cover 20 can be suspended After leaving, the wheels 200 shaped on the first module 41 and the second module 51 are exposed, and then the hanger is hooked (not shown) on the second die plate 50, and the second die plate 50 and its fixing are fixed. The second module 51 is hoisted, and then the middle seat 30 positioned there is released, and then the shaped wheel 200 is removed, and then the finished product demolding step 304 can be completed to make the wheel 200.

From the above description, it is not difficult to find that the feature of this creation is that with the non-inflatable wheel infusion molding device 100 of this creation, the wheel 200 can be made after the rubber is poured. Due to its non-inflatable wheel 200, it can be directly mounted on the vehicle as a wheel. Compared with known inflatable wheels, no tire pressure control is required, and no sharp objects are exposed to the wheels. The problem of flatness or puncture occurs in the middle, so it can have its convenience and safety in use. In addition, the non-inflatable wheel infusion molding device 100 of the present invention is that the outer ring 201, the spoke 202, and the inner ring 203 of the produced wheel 200 can be relatively thin, and still have a certain rigidity, so it can also be lightweight. And the effect of less material and low cost.
