Golf club head and its wax mold making method

Abstract

The invention relates to a process of preparing golf ball arm bulb and its wax mold, comprising following steps: preparing a first wax mold part by using a the first mode assembly, said first wax mold comprises a connecting part; putting said first wax mold into a first mold nest of the second mold assembly, said the first mold nest corresponding to the first part shape of preset bulb; injecting wax into a second mold nest of the second mold assembly, said second mold nest corresponding to the second part shape of preset bulb; cooling said wax in the second mold nest to form a second wax mold part, which is connected to connecting part of the first wax mold part; thus a wax mold bulb is formed, and bulb cast can be produced. The invention can produce smooth wax mold connecting surface, which improves wax mold connecting quality, increases plainness of bulb surface, and reduces mould-clearing cost.

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
