Description

Technical Field

[0001] The utility model relates to the field of automobile parts production, in particular to a mold capable of producing different supporting pads. Background Art

[0002] The pad is installed on the tire blowout emergency safety device and plays an auxiliary supporting role. It can support a certain height to realize the function of the tire blowout emergency safety device.

[0003] As one of the lower-level loose parts of the tire blowout emergency safety device, the pad directly contacts the bottom of the wheel groove. Since the shapes of the bottom of the wheel groove vary greatly, there is no uniform requirement for the bottom size of the wheel groove in the national and industry standards. When targeting groove bottoms of different shapes, different tire blowout emergency safety device support pads are required to match and install them.

[0004] At present, different molds are designed for different support pads, which results in too many types of molds and increases the cost of mold replacement. Utility Model Content

[0005] The utility model is based on the above technical problems and proposes a mold capable of producing different supporting pads.

[0006] A mold capable of producing different support pads comprises: a lower mold, wherein the four corners of the lower mold are provided with column holes, a cavity and a feed hole and a feed channel connected to the cavity are provided in the lower mold, an exhaust hole is provided in the cavity, two circular grooves are provided at opposite corners in the cavity, a boss is installed in the groove, a groove is provided in the center of the boss, the top surface of the boss is parallel to the cavity directly below it, and the top of the boss is also provided with a chamfer.

[0007] Preferably, the boss is detachably mounted, the boss is a cylinder, and is tightly mounted with the groove.

[0008] Preferably, the top end surface of the boss is higher than the groove.

[0009] Beneficial effects: The groove of the mold is used for the molding of the support pad. For different support pads, a boss can be installed in the groove. A slot is provided in the center of the boss. The support pad is made by using the boss and the slot, so the mold is more practical. By using a set of molds to produce different support pads by changing the type of the boss, the cost of mold replacement can be reduced and the number and types of molds can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 Shows a schematic diagram of the structure of the utility model;

[0011] Figure 2Shows Figure 1 A magnified view of the installation of the middle bump;

[0012] Figure 3 The schematic diagram of the structure of the first tire blowout emergency safety device is shown;

[0013] Figure 4 A schematic structural diagram of a second tire blowout emergency safety device is shown. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] like Figure 1~Figure 4 A mold that can produce different support pads 11 is shown. The four corners of the lower mold 1 are provided with column holes 2. The lower mold 1 is a part of the mold. It cooperates with the upper mold to produce a tire blowout emergency safety device 10. Support pads 11 are provided at two diagonal positions on one side of the tire blowout emergency safety device 10.

[0016] The lower mold 1 of the mold is provided with two independent cavities 3 and a feed hole 4 and a feed channel 5 connected to the cavities 3. The feed channel 5 is arranged in the middle and can connect the two independent cavities 3. The cavity 3 is provided with an exhaust hole 6. The cavity 3 is provided with two circular grooves 7 at the diagonals. The grooves 7 correspond to the position of the support pad 11 and are used to make the support pad 11. The grooves 7 are a concave structure.

[0017] When a support block 11 of a different shape is needed, a boss 8 is installed in the groove 7. The boss 8 is detachably installed. The boss 8 is a cylinder and is tightly installed with the groove 7. A slot 9 is provided in the center of the boss 8. The cavity 3 is designed according to the tire blowout emergency safety device 10, so the bottom surface of the cavity 3 is a transitional arc surface, and the top surface of the boss 8 is an inclined surface parallel to the cavity 3 directly below it, so that the support block 11 and the tire blowout emergency safety device 10 form a tight integrated structure. In addition, the top surface of the boss 8 is higher than the groove 7, and a chamfer is provided at the top of the boss 8. The chamfer setting can facilitate the assembly of the support block 11 after molding.

[0018] like Figure 3 As shown, the support pad 11 of the first type of tire blowout emergency safety device 10 is produced by a mold without the boss 8 being placed.

[0019] like Figure 4As shown in the figure, the support block 11 of the second type of tire blowout emergency safety device 10 is produced by a mold for placing the boss 8. The support block 11 in the figure is prepared by the groove 9 in the boss 8, and the concave part of the outer circle of the support block 11 corresponds to the top structure of the boss 8.

[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
