Golf club head and its wax mold making method

Abstract

A method for manufacturing a golf club head and a wax mold thereof, comprising the steps of: using a first mold set to prefabricate a first wax mold part, the first wax mold part having a joint part; the first wax mold part; The part is placed in a first mold cavity of a second mold set, the first mold cavity substantially corresponds to the shape of the first part of a predetermined club head; the wax liquid is injected into a second mold cavity of the second mold set, the The second mold cavity substantially corresponds to the shape of a second part of a predetermined club head; and the wax liquid in the second mold cavity is cooled to form a second wax mold part, and the second wax mold part is integrally combined with the first wax mold On the junction of the parts, they together form a head wax mold for precision casting of a head casting. In this way, the present invention can form a smooth bonding surface of the wax mold, thereby increasing the bonding quality of the wax mold, increasing the surface flatness of the rod head casting, and improving the good rate of subsequent casting, and at the same time, the structure of the wax mold mold is relatively simplified, and the manufacturing process is reduced. complexity and reduce mold opening costs.

Description

technical field [0001] The present invention relates to a manufacturing method of a golf club head and its wax model, in particular to prefabricating a first wax model part, and the first wax model part is combined with a second wax model part by direct injection of wax in a mold group. The wax mold part is used to make an integrally formed club head wax mold, thereby improving the manufacturing method of the subsequent club head casting quality. Background technique [0002] A method for manufacturing a conventional golf club head and its wax pattern, comprising the steps of: (1) making a wax pattern mold, and pouring wax liquid into the cavity of the wax pattern mold to form a club head after the mold is opened Wax model; (2) Dip the rod head wax model into a sand shell mold, then heat the sand shell mold, pour out the wax liquid hot melt, so that a mold cavity corresponding to the shape of the rod head is formed in the sand shell mold (3) inject hot-melt molten metal int...

Problems solved by technology

However, since the filler a' usually has a relatively high viscosity, for example, the viscosity of wax at 100° C. is above 100 cps, the filler a' is not only difficult to capillary fill into the gap a, but also when it contacts the wax molds 11 and 12 It is very easy to cool and solidify and stick to the surface of the gap a

As a result, although the filler a' can fill the gap a, it causes irregular protrusions on the surface of the junction, which leads to the need for more repeated surface grinding processes for the subsequently manufactured rod head 14 casting (not shown).

Especially, if the irregular protrusion is formed at the junction of the back cavity 141 of the casting of the rod head 14, it is difficult for the workpiece to enter the back cavity 141, so the surface grinding process in the back cavity 141 will become extremely difficult. Difficult, resulting in a substantial increase in processing costs and prolonging the process time
