Abstract

The utility model relates to a wax mould for manufacturing golf club heads, solving the problem for enhancing quality. The wax mould of golf club heads has a hitting ball surface, a connecting sleeve and a hollow hole of a bottom. The utility model is characterized in that the wax mould has a toe part whose side is provided with a casting post of an evagination, and the loading surface of the casting post is in an 'n'-shaped model. The utility model is used for manufacturing the golf club heads.

Description

The wax-pattern of glof club head

The utility model relates to wax-pattern, refers in particular to a kind of wax-pattern that post is arranged at the making glof club head of wax-pattern toe that waters that is the sprue gate.

The wax-pattern 3 of existing glof club head, shown in Fig. 3,4: it is mainly formed the appearance of a glof club head by striking surface 31, adapter sleeve 32, bottom hollow hole 33, and its tail end is the toe 34 that is commonly called as; Appropriate locations are provided with a solid post 35 that waters near the adapter sleeve 32; And the manufacture process of general glof club head, be that it is watered post 35 vertical sticking moulding 2 bottoms of being located at, and it is inserted make it in the mud to attach, and the adapter sleeve 32 of wax-pattern 3 is blocked, treat to attach mud five times through continuous again after its drying, make its grout wall mask that attaches the thickness of desirable strength be arranged and form a die holder, and make its molten steel weight of can loading.Utilize high-temperature steam dewaxing, water post 35 and form a sprue gate 35, and adapter sleeve 32 updip slightly.The wax liquid that will dissolve is at last poured out from the hand-hole 21 of moulding 2.Molten steel injects from the inlet 21 of moulding 2, utilizes each sprue gate 36 to make it to flow into the hollow die cavity in the die holder and cools off and finalize the design.But, because the post 36 that waters of this wax-pattern 3 is the sides that are arranged at the bar head, therefore, when the perfusion molten steel, very easily hinder toward the adapter sleeve that tilts, make the flowing velocity speed of molten steel differ more because of being subjected to the bar head, extremely can be because of the influence of cooling velocity difference and flow rate near the molten steel at toe 34 places, make its surface form the tiny hole and the sand hole in hole, concavo-concave hole easily, and destroyed the quality of this glof club head; In addition, be a solid cylinder because of watering post 36, therefore, 36 positions, sprue gate of the glof club head after moulding also form a solid cylinder, when in carrying or under the influence of other factors, produce stress when especially cooling is shunk, damage and produce the crack, add that these 36 positions, sprue gate do not have the space that buffering forms, thus the as easy as rolling off a log structural failure that causes glof club head itself, and influence its quality.

The purpose of this utility model provides a kind of wax-pattern of improved glof club head.

The purpose of this utility model is achieved in that the wax-pattern of glof club head, this wax-pattern has striking surface, adapter sleeve, reaches the bottom hollow hole, and it is characterized in that: wax-pattern has the post that waters that the toe side is provided with an evagination, and this section that waters post is a Jiong word moulding.

Above-mentioned design, because the sprue gate is located at the toe side, thus not hindered by adapter sleeve during the perfusion molten steel and evenly descend in regular turn, flow speed stability, the surface does not have sand hole, has reached the effect that improves the quality.

Below by drawings and Examples the utility model is described further again.

Fig. 2 the utility model and moulding link schematic diagram;

Fig. 3 has wax-pattern three-dimensional appearance schematic diagram now;

Existing wax-pattern of Fig. 4 and moulding link schematic diagram.

As shown in Figure 1, 2: wax-pattern 1 of the present utility model has striking surface 11, adapter sleeve 12 and bottom hollow hole 13, and what the side of its toe 14 was provided with an evagination waters post 15, and this cross section of watering post 15 is a JiongZi Xing moulding.Wax-pattern 1 is sticking to be located at moulding 2 bottoms and to water post 15 up, and adapter sleeve 12 tilts down, and watering post 15 and can forming a sprue gate 16 of wax-pattern 1 so molten steel can evenly descend smoothly with three sidewalls at sprue gate 16, guaranteed the casting quality.

Claims

1, the wax-pattern of glof club head, this wax-pattern have striking surface, adapter sleeve, reach the bottom hollow hole, and it is characterized in that: wax-pattern has the post that waters that the toe side is provided with an evagination, and this section that waters post is a Jiong word moulding.
