Two-Location One Step Injection Tyre Capsule Vulcanizing Machine

Compression molding is a traditional method in order to produce early capsule. Ithas many disadvantages as fllows: the low quality of capsule; the low efficiency;complex technics process; wasting energy and high labor intension and so on. Moreand more tyre bladder will adopt the injection molding method in order to adapt themore development of it. It has many advantages: high production efficiency; less waste;saving material and high physics capability of capsule. But traditional injection methodhas many disadvantages: Its work has two processes. The first is plasticization andquantification. And the second is injection. The equipment used by the method isexpensive and has very complex structure. The paper has a new design according to thedisadvantages of traditional injection methods. So two-location one step injection tyrecapsule vulcanizing machine has been finished. It improvs the capsule quality andefficency; It saves energy and material. And it realize the civilization in the production.So production technique oftyre capsule has received the new day.The paper has deeply researched operation principle of two-location one stepinjection tyre capsule vulcanizing machine and merit and shortcoming of conventionalvacalnizing equipment. By theoretic deduce,building up the mathematics model ofconsuming power about multi-location injection molding machine, stress and strain,moreover, carrying out the relational design calculation and ANSYS analysis,havingdesigned completely new multi-location injection molding machine. Finally, for thesake of guaranting the feasibility and reliability of structure,the parameterizedthree-dimensional simulation design and dynamic process dynamic simulation ofmulti-location injection molding machine are used. The principally innovation ideas ofthe thesis as follows:1. First the whole structure of two-location one step injection tyre capsulevulcanizing machine is designed in the paper, which is proved that stress is reasonable,distortion is slight. It overcomes the shortcoming of conventional equipment,and carrys out high-capacity injection. This is a breakthrough in the multi-location injectiondesign.2. Underside injection is adopted first. It also means the injection nib and flowpassage are under of mould. Rubber matiaral flow from down to up in the mould. Themethod overcomes the eccentricity of inner mould which is aroused when injection nibis in the middle of mould(departing shape face).3. The machine use electric magnetic clutch and ball screw at the same time. Themethod slove the problem which is aroused by the change of injection nib(compared tothe traditional injection and demould technics).4. In this paper, two-diamensional moving equipment for multi-working spots isnewly designed. It adopt the high exact ball slide guide strip and AC servo-actuator. Itmeets the requirement of orientation credibility, and it solves the problem that therubber is prone to vulcanized while waiting next injection in single-working spot.5. First the principle of one step injection is managed in the process of capsuleproduction. It realize the synchronization of plasticization, quantification and injection.It also overcome many disadvantages of traditional production methods: low quality ofcapsule, wasting energy and low production efficiency and so on.6. The structure design, from which high injection pressure needed is guaranteed.It mainly include higher length diameter ratio, shorter pitch of screw in transfer zone,adopting intermeshing helical feeding roll to increase pressure, setting the bearing boxin the front of reduction box to improve the suffering condition.7. The thesis process some innovation in the designing of the new concept press instructure oftyre capsule vulcanizing machine. The innovation adopts screw framework. Its track is vertical andreciprocate. The press instructure combines with sensor. So the structure has many advantageswhich are stability and precision of the equipment. The designing embodiment the innovational andoptimizing thinking.8. ANSYS is used in accessorial design. The design combined theoretic deduceand ANSYS analysis,which improves the reliability of structure design.9. This design successfully combines the traditional design with the threedimensional simulation design and process dynamic simulation design method,whichdeduces design cycle, reduces cost. The ynchronization modern design idea of hedesign and the manufacture has fully manifested.
