Abstract
The present invention relates to a ceramic core for a golf club head, particularly to a zirconia ceramic core for a titanium alloy golf club head casting. The present invention is prepared from the components of the percentage by weight: 64 to 96% of Zr2O2, 1.5 to 15% of zircon sand, 0.0007 to 5% of plasticizing agent, 0.0007 to 8% of adhesive, 0.00007 to 6% of wetting agent and 1.5 to 12% of solvent. The zirconia ceramic core prepared by the present invention is suitable for continuous production in an extrusion method, and the core has high compactness, surface smoothness and dimensional precision; the core can resist the scouring effect of centrifugal force and liquid metal in a casting process, and the zirconia ceramic core and titanium and high-temperature alloy liquid thereof have no obvious reaction phenomenon; thus, the golf club head casting which is placed in a core position has no flaw, and various physical properties of the titanium alloy materials are not destroyed; after pouring is finished, the ceramic core can be conveniently taken out from the golf club head casting by the traditional core drilling method.
Description
Technical field
The present invention relates to a kind of golf club head cast ceramic cores.
Background technology
Titanium is a kind of extremely active element, at high temperature reacts with many elements and compound, causes very big difficulty for the founding of this metal and alloy.Titanium and alloy thereof must be in foundings under the vacuum condition, and employed casting mold can not tangible reacting phenomenon take place with high temperature titanium liquid.And during the golf club head precision casting, employed core requires strict more, except not taking place also to require to have certain intensity the significantly reaction with titanium liquid, could when centrifugal casting, resist washing away, vibrating of liquid metal, and will be convenient in foundry goods, take out.At present, the ceramic core that is used for the golf club head precision casting adopts the preparation of hot pressing injecting method, and its is fit to short run, complex-shaped ceramic product.
Summary of the invention
Employing of the present invention and titanium and alloy thereof form the method for good inert substance and prepare titanium alloy golf bar head foundry goods zirconia ceramics core, it both can satisfy the requirement of golf club head precision casting, made golf club head precision casting pipe portion bore surface not form any flaw phenomenon again.The present invention is mixed by following compositions in weight percentage: ZrO
264～90%, zircon sand 1.5～15%, softening agent 1～5%, binding agent 1～8%, wetting agent 1～6% and solvent 1.5～12%.The zirconia ceramics core of the present invention's preparation is fit to the extrusion process continuous production; The compactness of core, surface smoothness and dimensional precision height; In casting cycle, can resist the souring of centrifugal force and liquid metal; Tangible reacting phenomenon does not take place in zirconia ceramics core and titanium and alloy high-temp liquid thereof, and golf club head foundry goods placing core position does not form any flaw, does not destroy the various physicalies of titanium alloy material; Behind the casting complete, utilize traditional brill core method, can in the golf club head foundry goods, take out ceramic core easily.
