Description

Engineering tire rib mold

technical field

The utility model relates to the technical field of tire manufacturing, in particular to an engineering tire rib mold used for engineering vehicles.

Background technique

The shape of the tire used by various vehicles and the various patterns on the tire are generally put into the tire mold of the vulcanizing machine and vulcanized under certain temperature and pressure conditions. The shape of the tire pattern, It depends on the shape of the ribs on the contact surface between the tire mold and the tire blank.

Wherein the two half tire molds are a class in the tire vulcanization mould. In the prior art, the ribs of the upper mold body and the ribs of the lower mold body are made separately, and the ribs of the upper mold body are made by setting the wax pattern of the wax pattern of the upper mold body Use the investment casting process to form the wax mold of the upper mold body ribs, and the lower mold body ribs are made in two steps by setting the lower mold body ribs wax pattern, and then using the investment casting process to form the lower mold body ribs wax mold , the so-called investment casting process is to use fusible material (such as: wax) to make a model, then wrap it with modeling material, after hardening, and then melt the model, so as to obtain a casting without parting surface method.

As shown in Figure 5, when making the upper mold body flower rib model, the upper mold body flower rib wax model 51 is put into the upper mold body flower rib wax mold blank 52; as shown in Figure 6, when making the lower mold body flower During the rib model, the lower mold body flower rib wax pattern 61 is put into the lower mold body flower rib wax mold blank 62, and the upper mold body flower rib wax mold blank 52 and the lower mold body flower rib wax mold blank 62 are aluminum alloy respectively structure.

The separate blanking of the rib wax mold of the upper mold body and the wax mold of the lower mold body to make the mold is due to the different shapes and sizes of the ribs of the upper mold body and the lower mold body, which is different from the parting surface of the tire mold. It is related to the design and the structure of the tire tread. By analyzing the pattern structure of the tire, it is found that the pattern structure of the two halves of the tire mold in the prior art is roughly divided into two types, as shown in Figure 8, one is that the pattern 81 of the upper mold body and the pattern 82 of the lower mold body are opposite to the half surface of the tire. It is a mirror image relationship with a positioning difference, referred to as a mirror image relationship; as shown in Figure 7, the other is that after the pattern is rotated 180° along the top of the tire, the upper mold pattern 71 and the lower mold pattern 72 are the same, referred to as a rotation relationship. The two patterns with different structures have a great impact on the processing cost. According to statistics, in the pattern structure of the two halves of the tire mold, the proportion of the pattern of the mirror image relationship is less than 5%, while the proportion of the pattern of the rotation relationship is less than 5%. It is more than 95%, so the pattern of the rotation relationship is the main one. If the upper mold body rib model and the lower mold body rib model are respectively set with their own wax patterns and models, it will cause a substantial increase in material and processing costs. It is not conducive to reducing procedures, improving production efficiency and reducing production investment.
