Abstract
The present invention relates to a method for making a ceramic core of a golf club head casting with an extruding method, particularly to a making method for a ceramic core of a golf club head casting. The present invention is realized through the following steps: step a, a skeletal material, a mineralizing agent, a plasticizing agent, a caking agent, a wetting agent and a solvent are proportionally weighed; step b, the skeletal material, the mineralizing agent and the powdery caking agent are put in a dry mixing machine; step c, the materials uniformly mixed in a dry mode are put in a wet mixing machine, and the plasticizing agent, the wetting agent and the solvent are orderly added in the process of the stirring and the mixture of the materials; step d, the materials uniformly mixed in a wet mode are put in a pug mill, and the pugging of the materials is carried out; step e, the materials processed through the pugging are put in a closed container and stood for several hours under the condition of a moderate temperature, and plasticity blank materials are obtained; step f, the plasticity blank materials are extruded into a blank on an extruding molding machine, and then, the blank is cut into blank segments; step g, the blank segments are dried; step h, the blank segments are sintered in a high temperature sintering furnace; step i, the fine processing of the sintered workblanks is carried out. The present invention can carry out multitudinous continuous production, and the defects, such as cracks, gas holes, deformation, deboss, etc., are eliminated.
Description
Technical field:
The present invention relates to a kind of preparation method of golf club head cast ceramic cores.
Background technology:
At present, the ceramic core that is used for the golf club head precision casting adopts the preparation of hot pressing injecting method.Because the hot pressing injecting method is a softening agent preparation ceramic size with thermoplastic material (as paraffin), hot pressing forms shape, and high temperature sintering becomes core.The ceramic core intensity of this method preparation is low, dimensional precision is low, easily produces following defective: shrink big, density is low and inhomogeneous, distortion, crackle, pore, depression, and hot pressing injecting method mould complexity, manufacturing cycle are long; Production efficiency is low, is not suitable for the production in enormous quantities of the such simple shape of golf club head precision casting ceramic core (cylindrical) part, and its is fit to short run, complex-shaped ceramic product.
Summary of the invention:
The purpose of this invention is to provide a kind of pressing method for preparing the golf club head cast ceramic cores, it is continuous production in enormous quantities, enhances productivity; Improve product density and homogeneity; The ceramic core radial dimension precision of golf club head precision casting is reached ± 0.02 millimeter; And eliminate defectives such as crackle, pore, distortion, depression.The present invention is achieved in that a, batching: the weighing in proportion of aggregate, mineralizer, softening agent, binding agent, wetting agent, solvent; B, dried mixing: aggregate, mineralizer and powder binder are put into dry-mixed machine mix; C, wet mixing: putting into the wet mixing machine do mixing uniform material, mixing and add softening agent, wetting agent and solvent in the process successively, thorough mixing is even; D, pugging: the uniform material of wet mixing is put into the pug mill pugging, binding agent, softening agent, wetting agent, solvent, aggregate, mineralizer are squeezed in pug mill practice more than 20 minutes,, obtain the good plasticity-blank of compactness simultaneously by vacuum stripping; E, old: the material through pugging is put into airtight container, under 20～30 ℃ condition, placed 12～24 hours, obtain the plasticity-blank; F, crowded base: on single-lead-screw extruding briquetting machine the plasticity-blank is extruded into cylindrical parison, being cut into pieces then is transferred on the travelling belt, dries 10～20 minutes down at 25～60 ℃; G, drying: following dry 3～7 days at 20～30 ℃ then; H, sintering: dried blank is put into high temperature sintering furnace 1200～1500 ℃ of following sintering 8～14 hours; I, precision work:, finish final finished to carrying out simple precision work through the blank behind the high temperature sintering.The present invention prepares the golf club head cast ceramic cores with pressing method, owing to adopt the plasticity-blank, the hole of having avoided gas in the traditional technology slurry and wax material to form, defective such as longitudinal crack, distortion, and improved compactness, surface smoothness and the dimensional precision of ceramic core at the squeeze compacted under, make golf club head precision casting ceramic core radial dimension precision reach ± 0.02 millimeter; Extrusion process can form successive, automatic production, and mould is simple, the manufacturing cycle is short, the production efficiency height; This processing method can be continuously, automatic production, is suitable for producing in enormous quantities, can be applicable to the golf club head precision casting ceramic core preparation of various alloys (all metals and alloys such as titanium alloy, soft iron, spheroidal graphite cast iron and stainless steel).
