Description

Tire mold with detachable pattern module Technical Field The utility model relates to the technical field of tire molds, in particular to a tire mold with a detachable pattern module. Background The tire mold is core equipment for tire vulcanization molding, and the design precision and the structural flexibility of the tire mold directly determine the production efficiency and the product diversity of the tire. In the field of tire manufacturing, tires of the same specification often need to develop various pattern styles to meet market demands (such as pattern differences of road tires and off-road tires), while pattern structures of conventional tire molds usually adopt integral type fixing designs, namely pattern blocks are permanently connected with mold bodies through welding, bolt fastening and other modes. The main defects of the prior art are that the pattern replacement cost is high, when tires with the same specification and different patterns are required to be produced, the whole set of die is required to be reprocessed, and the production flexibility is insufficient. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a tire mold with a detachable pattern module. In order to achieve the aim, the tire mold with the detachable pattern modules comprises an upper mold assembly and a lower mold assembly which are arranged in an up-down involution way, wherein a plurality of pattern modules are detachably connected to the involution surfaces of the upper mold assembly and the lower mold assembly; The mounting mechanism for positioning and mounting the pattern module is arranged between the upper die assembly and the lower die assembly and comprises a plurality of sliding grooves distributed along the circumferential direction of the die, the sliding grooves respectively penetrate through the joint surfaces of the upper die assembly and the lower die assembly, each sliding groove is internally provided with a clamping block in a sliding fit manner, and the back of the pattern module is provided with a clamping groove matched with the clamping block. The tire mold has the advantages that the clamping blocks are clamped into the clamping grooves by the sliding clamping blocks, so that the pattern modules can be installed in the upper mold assembly or the lower mold assembly, and the pattern modules can be replaced on the contrary, so that the situation that the production cost is increased because the pattern modules on the existing tire mold are usually fixedly connected to the mold and the tire factories want to produce tires with the same specification and different pattern styles is avoided. Preferably, one side of the clamping block back to the clamping groove is fixedly connected with a cylindrical rod penetrating through the lower die assembly, and the cylindrical rod and the lower die assembly are in sliding fit to form a guide structure. The component has the advantages that a worker can drive the buckling block to slide by sliding the cylindrical rod, so that the operation is more convenient. Preferably, a reset spring is sleeved on the cylindrical rod, and two ends of the reset spring are respectively abutted against the inner walls of the clamping block and the sliding groove and used for providing reset elastic force for the clamping block to be clamped into the clamping groove. The upper die assembly or the lower die assembly has the advantages that when the pattern module is inserted into the upper die assembly or the lower die assembly, the pattern module pushes the inclined surface of the buckling block, so that the buckling block is clamped into the sliding groove, the reset spring is in a contracted state, and when the buckling block is contacted with the clamping groove, the buckling block is clamped into the clamping groove under the action of resilience force of the reset spring, so that the operation is more convenient. Preferably, adjacent pattern modules are connected through a detachable clamping structure, one end of each pattern module is convexly provided with a connecting lug, the other end of each pattern module is provided with a connecting groove matched with the connecting lug, and the connecting lug and the connecting groove form a modularized splicing structure. The connecting lug on one pattern module is clamped into the connecting groove on the adjacent pattern module when the pattern module is installed, so that a plurality of pattern modules can be connected together, and the single damaged pattern module can be replaced conveniently. Preferably, an arc-shaped matching structure is arranged between the lower die assembly and the upper die assembly as a connecting mechanism, and the connecting mechanism comprises an arc-shaped clamping groove formed in the matching surface of the lower die assembly and an arc-shaped clamping block fixedly connected to the matching surface of the upper die assembly, and the arc-shap
