Specication o! Letters Patent.
Patented May 26, 1914.
Applieationlled October 26, 1910. Serial No. 589,119.
To all whom it may concern:
Be it known that I, 'EDGAR A. CUsTER, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented certain new and useful proveniente in Permanent Metal Molds, of which the following is a specification, reference being had to the accompanying draw-` ings forming a part thereof. Y
The object of this invention is to provide means in a permanent metal mold whereby injury to the mold caused by the molten metal as it enters the matrix through the gate may be avoided.
A further object of the invention is to provide means whereby the dimensions of the gate may be Varied without reconstructing the mold.
`The variousother objects of the invention will be more fully set forth in the following description of one form of permanent mold embodying my invention, which consists in the' new and novelfeatures of construction and combinations of'v parts hereinafter set forth and claimed.
In the-accompanying drawings: Figure l is a side elevation of a section of a metal mold embodying my invention. Fig. 2 is a therein, so that water plan view of the same in section.
Referring to the drawings, which show one form of a mold embodying my invention, the mold comprises two parts or sections a which are hinged together as at b. Preferably the meeting face of each section of the mold is suitably recessed as at c to receive an insert d. Both the mold and the inserts are recessed or channeled to form the sprue c, the gate f and the matrix g. Preferably a part of the sprue and all of the gate are formed in the inserts, which may be of sui'licient length to form a part of the wall `of the matrix as at t. The casting z' may be poured around the removable cores y' which are inserted within the matrix.
One or more channels may be provided in the insert, which communicate with a supply pipe Z having a suitable valve m or other cooling Huid may be caused to flow through the insert in order to control the temperature thereof and to prevent the insert from becoming heated above any desired 'maximum temperature through contact with the molten metal passmg through the gate, and also to cause the metal of the casting contiguous to the gate to set simultaneously with'the metal in the other parts of the casting. f
The insert may be of an`y suitable mate rial. In practice, the insert may be made of a different metal than the body of the mold for the purpose of either promoting or retarding the radiation of heat, or it may be made of some different material such as a combination of fullers earth with talc or lava rock which will be able to withstand the harmfulefi'ects of the molten metal.
Heretofore much damage has been caused by the cracking of permanent molds at or near the gate, whichresulted in the practical destruction of the mold itself, since the cracks so formed could not be removed or repaired. By means of this construction the parts of the mold most subject to injury can be readily removed and a new insert put in place. Furthermore 'it is obvious that the size of the sprue and of the gate may lbe changed by substituting inserts having different sized channels or recesses formed therein.
I claim as my invention:
l. In a permanent metal mold comprising sections, an insert detachably secured to one of `the sections and adapted to Contact with the molten metal supplied to the mold, said insert forming part of the face of said section and being formed of different material than the section.
9.. In a permanent metal mold comprising sections, the combination with each section, of an insert detachably secured to said section and adapted to contact with the molten metal supplied to the mold, each insert being formed of different material sections and each having a portion of the sprue and the entire gate formed therein.
3. In a permanent metal mold comprising` sections the combination with each section, of an insert secured to said section and adapted to contact with the molten metal supplied to the mold, each insert having channels formed therein for the passage of a liquid andy forming part of the wall f the sprue'and the matrix.
4. In a permanent mold comprising secthan the g Y v1,097,849
tions, the combination with each section, of an insert secured to saidseetion and being channeled to form a portion of the gate and i This specii'cation signed and witnessed this 15th day 'of October A. D., 1910.
