Benefits of technology

[0009]The present invention also includes a method comprising the steps of loading a volume of molten zinc into a chamber of a dispenser station, dispensing the molten zinc from the chamber of the dispenser station through a hot runner and into a mold cavity defined by a mold housing and a mold cover, continually maintaining the molten zinc in a molten state from a source of molten zinc to the mold cavity, interrupting the flow of the molten zinc to the mold cavity, following the contraction of the molten zinc in the mold cavity by maintaining sufficient pressure on the molten zinc as it solidifies therein to inhibit formation of air bubbles, and removing the solidified die-cast zinc product from the mold cavity. Once removed, a finishing surface treatment may then be applied solidified die-cast zinc product.

Problems solved by technology

However, conventional die-casting methods have been known to produce die-cast products that are prone to develop surface imperfections when the user attempts to place a finish surface treatment on the die-cast product

Embodiment Construction

[0015]FIG. 1 shows a schematic diagram of an embodiment of a system 10 for die-casting products free or substantially free of surface blemishes or imperfections. System 10 generally comprises a dispenser station 11 connected to both a mold station 12 and a source of molten zinc 13 with the dispenser station 11, mold station 12 and source of molten zinc 13 linked to a control system 14 that controls the operations thereof. Mold station 12 is also shown connected to a finishing station 26 that is also linked to control system 14, which also controls the operations of the finishing station 26. Finishing station 26 applies a finishing surface treatment to the solidified die-cast products, for example by electroplating, painting or the like. The control system 14 may comprise a variety of devices, such as a computer or a microprocessor-based device, that is capable of monitoring and sending out operational commands to the dispenser station 11, the mold station 12, the source of molten zi...

Abstract

A system and method of preventing surface imperfections of die-cast products with the method comprising the steps of loading a volume of molten zinc from a source of molten zinc into a chamber of a dispenser station, dispensing the molten zinc from the dispenser station through a hot runner and into a mold cavity, continually maintaining the molten zinc in a molten state from the source of molten zinc to the mold cavity, interrupting the flow of the molten zinc to the mold cavity, following the contraction of the molten zinc in the mold cavity as the molten zinc solidifies therein; and removing the solidified die-cast zinc product from the mold cavity.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]NoneSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]NoneREFERENCE TO A MICROFICHE APPENDIX[0003]NoneFIELD OF THE INVENTION[0004]This invention relates generally to die-casting devices, and more specifically, to a system for die-casting products having reduced surface imperfections and a method of improving the surface properties and inhibiting or preventing surface imperfections and cracking of die-cast products such as zinc products.BACKGROUND OF THE INVENTION[0005]Die-casting of parts is known in the art and generally has been adequate for most of their intended purposes. However, conventional die-casting methods have been known to produce die-cast products that are prone to develop surface imperfections when the user attempts to place a finish surface treatment on the die-cast product[0006]In order to solve the above problem, the inventor has discovered that when die-cast zinc products are manufactured in which the...
