Zhongwei Precision has two divisions: Precision Casting Hardware Division and Golf Equipment Division.

The main products of the Precision Casting Hardware Division:

1. A series of architectural hardware, such as: glass door clips, hinges, connecting claws, hinges, locks, door handles, pins, feet, stainless steel pot handles.

2. Hardware precision castings of stainless steel, carbon steel and alloy steel such as: daily hardware, mechanical equipment spare parts hardware, power tool hardware, tableware and kitchen hardware, medical equipment, electroplating hangers, automobile and motorcycle accessories, pipe valve hardware, etc. Castings and machined finished products.

The main products of the golf equipment division:

1. OEM Dunlop, Ram, Golden bear, U.s.kids golf, Knight and other foreign brands. The monthly output is 350,000 small ball heads and 50,000 large ball heads.

2. Self-developed "Eagle Wolf" series of golf equipment.

3. Independently develop lost wax casting titanium alloy and aluminum alloy golf head.

4. We can tailor golf equipment with our own unique style. The company undertakes OEM processing with drawings and samples, and can provide precision casting or precision casting machining services, such as machining, polishing, electrolytic polishing, according to customer requirements. , electroplating, etc.

There are generally three kinds of golf head materials (titanium alloy, stainless steel and carbon steel), the most popular stainless steel on the market, but the hardness of stainless steel is also relatively high, and polishing also has requirements on the weight of the golf head, and the final polished product is produced. The error is only 5 grams, which is undoubtedly more difficult for manual polishing. Will Golf head lost wax casting be your choice?

Golf head lost wax casting die head:

The utility model relates to a ball metal casting device.

When the existing stainless steel golf head is manufactured, a metal mold (such as an iron mold) or a wooden mold is first machined, and then a wax mold is made according to this mold, and a layer of refractory material is fixed on the surface of the wax mold, and then blowing on it. The steam is injected, and the wax mold is melted by its heat, that is, a so-called shell mold is formed. After sintering at a high temperature of about 1200 °C, high-temperature molten steel is poured from the die nozzle, so that the molten steel flows into each ball mold with the sprue. After cooling, the shell mold is broken to become a steel mold, and then the ball head on the lower side is sawed off, and the ball head product is completed after subsequent processing procedures such as panel mounting and grinding.

In the existing die head, a hollow conical sprue is extended on a hollow flat plate, and a head die is extended on each of the four corners and the middle two sides under the hollow flat plate. Such dies have long been used by metal ball manufacturers. Since the sprue is located in the center, when the molten steel is poured from the sprue, most of the molten steel will first flow down to the two ball-head dies in the middle after entering the flat plate, and then turn to flow direction after the two ball-head dies are filled. The ball head molds at the four corners make the temperature of the molten steel uneven in the four ball head molds. At the same time, due to the existence of air in the molten steel, after the molten steel is poured into the mold head, because there is no vent channel, it is easy to be in the ball head. Air bubbles formed in the mold. lead to an increase in the rate of defective products. In addition, due to the large area of the upper nozzle and the flat plate, the amount of molten steel required to be poured each time is increased, and after the ball head is cut off, the upper side has to be re-melted and burned into molten steel for use, resulting in a delay in the manufacturing speed and cost. rise.

The purpose of the utility model is to provide an improved stainless steel golf head casting die, so as to improve product quality and efficiency, and reduce product defect rate and manufacturing cost.

The utility model extends outward and radial runners below the original conical sprue of the die head, and is provided with air channels above each runner, and a ball head mold is extended below each runner.

The number of runners is preferably 6 or 7:

Compared with the existing stainless steel golf head casting die, due to the extended radiation of the nozzle

The ball mold has an independent runner. Therefore, when molten steel is poured from the nozzle

The molten steel can quickly and evenly enter each ball head mold from each runner; and because there is an air channel above the runner, and a ball head mold is extended below each runner, the refractory material is attached to the wax mold. When forming a shell mold, the sprue and air channel of the shell mold are connected with the nozzle, so when the molten steel poured into the ball head mold contains air, it can be discharged upward through the air channel without accumulating. When left in the ball head mold, the product will not produce air bubbles, which improves the quality and yield of the product.

In addition, since the sprue and runner have a significantly smaller area than the existing sprue and platform, the amount of molten steel required to be poured each time is less, that is, the waste remaining after the ball head is cut off. Relatively few, thus significantly improving ergonomics and reducing costs.

FIG. 1 is a perspective view of the structure of a casting die for a stainless steel golf head. FIG. 2 is a cross-sectional view of the structure of a casting die for a stainless steel golf head.

Example, as shown in Figures 1 and 2, the die head is composed of a conical sprue (1), a radial runner (2), an air channel (3) and a ball head die (4). The outward air channel extending below the conical sprue is set above each runner, and a ball head mold is extended below each runner, and the number of runners is preferably 6.
