AI Technical Summary
⚠Technical Problem
The existing mold guide mechanism lacks an effective sealing structure, which causes lubricating oil to diffuse into the product cavity, affecting product quality.
⚗Method used
Design a sealing and guiding mechanism for a mold, with an annular seal installed on the guide sleeve and an annular oil storage groove on the inner circumferential wall. The lubricating oil is adsorbed through the local negative pressure effect, and the seal is fixed by the pressure cover component to ensure seamless continuity of the guide surface.
🎯Benefits of technology
It effectively blocks the diffusion of lubricating oil into the product cavity, improves product yield, reduces frictional resistance and wear, and extends service life.

Abstract
The utility model relates to a sealing technology field of guide mechanism, concretely relates to a sealing guide mechanism of mould, include: guide component, guide component includes the guide pin and guide bush that mutually slide and cooperate, the guide pin fixed mounting is in the movable mould base plate of mould, the guide bush fixed mounting is in the fixed mould base plate of mould, the guide pin insertion end sleeve mouth department of guide bush is coaxially equipped with annular sealing element, the inside diameter of sealing element is same with the inside diameter of guide bush, to form the continuous guide surface, the inner peripheral wall of sealing element has the multiple annular oil storage grooves that continuously distribute along its axial direction. The section of each oil storage groove is V, U, C, trapezoidal arbitrary one, and the interval of adjacent two oil storage grooves is 0.5-1mm. Sealing element is fixed in the guide pin insertion end sleeve mouth department of guide bush through gland component, and the gland component is fixed on the fixed mould base plate through fastener. The utility model, the multiple annular oil storage grooves of sealing element inner peripheral wall scrape the oil stain, dust to sealing element inside, improve the yield of product.
