Abstract
The utility model discloses a precise detachable mould for bicycle tires, which comprises an upper and a lower moulds which are respectively composed of a mould case, at least one split plate and screws, wherein the screws are connected with the mould case and the split plates, air exhaust gaps are arranged between the split plates, and the split plate and the mould case, and an air exhaust path arranged in the mould causes the air exhaust gaps to be communicated with outside. The utility model has the advantage of convenient and reliable assembly, disassembly and cleaning, the produced bicycle tires does not need rubber strips, and the utility model is a novel bicycle tire mould with beautiful appearance and good quality.
Description
The utility model relates to a kind of bicycle tyre mould, and is especially relevant with accurate bicycle tyre activating mold.
Existing bicycle tyre mould is owing to be provided with steam vent, can stay defectives such as glue palpus after causing vulcanized tyre to be shaped at surface of tyre, influence the attractive in appearance and quality of tire, in can only being applied to, the production of low-grade bicycle tyre, can't satisfy and produce needs high-grade and the outlet bicycle tyre.
The purpose of this utility model provides a kind of surface of tyre of producing and does not stay glue must and to clean simple load and unload accurate bicycle tyre activating mold.
For achieving the above object, the utility model is realized by following technical solution: the accurate bicycle tyre activating mold of the utility model, comprise upper die and lower die, patrix and counterdie are by formwork, at least a slice assembly sheet and screw are formed, screw connects formwork and pieces together sheet, is being provided with exhaust clearance between the assembly sheet and between assembly sheet and the formwork, and the exhaust passage that is located in the mould is in communication with the outside exhaust clearance.
Described accurate bicycle tyre activating mold, the gap of its exhaust clearance is in 0.04 millimeter.
Described accurate bicycle tyre activating mold pieces together being provided with the alignment pin location between sheet and the formwork.
The utility model has been owing to adopted above-mentioned technical solution, thereby has following beneficial effect: (one) adopts active assembly chip on the structure, make clean, mounting or dismounting are convenient reliable; (2) be to utilize to piece together between the sheet and the exhaust clearance exhaust between assembly sheet and the formwork, cancelled steam vent, made the bicycle tyre of production can not produce the glue palpus, the tire outward appearance is beautiful, have good quality, can improve the bicycle tyre product competitiveness in market at home and abroad greatly.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the accurate bicycle tyre activating mold of the utility model.
Fig. 2 is the monnolithic case figure of the accurate bicycle tyre activating mold of the utility model.
As shown in Figure 1, accurate bicycle tyre activating mold is made up of patrix 1 and counterdie 2, patrix 1 and counterdie 2 are by formwork 3, piece together sheet 4 and screw 5 is formed for two, screw 5 connects formworks 3 and pieces together sheet 4, piece together between the sheet 4 and piece together be provided with between sheet 4 and the formwork 3 gap be 0.04 millimeter with interior exhaust clearance 6.As shown in Figure 2, on formwork 3, have exhaust passage 7, make exhaust clearance 6 be in communication with the outside, reach the purpose of exhaust by exhaust passage 7.Piece together for making that to be connected the location between sheet 4 and the formwork 3 more reliable, locate piecing together between sheet 4 and the formwork 3 employing alignment pin 8.
