The utility model discloses a change the feed inlet bottom of die casting machine feed cylinder into removable mold insert, can suffer erosion or high temperature in the feed inlet bottom and damage the time, only need change the mold insert and can realize the normal use of feed cylinder body. The present invention will be described in detail with reference to the accompanying drawings.
Example 1
The die casting machine includes die casting machine feed cylinder and heat fusion device, the feed inlet of die casting machine feed cylinder is just right heat fusion device's discharge gate for connect the high temperature molten metal liquid that heat fusion device poured greatly. Referring to fig. 1 and fig. 2, wherein fig. 1 is a perspective view of a die casting machine cartridge of the embodiment, and fig. 2 is a cross-sectional view of the die casting machine cartridge of the embodiment. Die casting machine feed cylinder includes feed cylinder body 10a, mold insert 20a, setting element 30a and bolt 40a, mold insert 20a passes through setting element 30a and bolt 40a set up in the feed cylinder body 10a, just the mold insert adopt with the same general hot die steel preparation of feed cylinder body, perhaps adopt the high temperature alloy material preparation that has high red hard.
Specifically, a feed port 11a and a mounting hole 12a are opened on a side wall of the cartridge body 10a, and the mounting hole 12a is opposite to the feed port 11 a. The charging barrel body 10a is provided with a body positioning groove and a body screw hole at the edge of the mounting hole. The size of the insert 20a is matched with that of the mounting hole 12a, and an insert positioning groove 21a corresponding to the body positioning groove is formed in the bottom of the insert 20 a.

Before installation, high-temperature sealant or high-temperature industrial mending agent is respectively coated on the edges of the installation matching surfaces of the insert 20a and the installation hole 12a, then the insert 20a is embedded into the installation hole 12a, so that the gap between the insert 20a and the edge of the installation hole 12a is completely filled, and then the redundant part is removed. The high-temperature sealant is a 1200-temperature-resistant inorganic high-molecular polymer sealant SL8081 or SQ2 high-temperature sealant from Shilin polymer Co., Ltd; the high-temperature industrial healant is a 1200 ℃ high-temperature TS767 resistant industrial healant. During disassembly, after the bolt 40a and the positioning piece 30a are disassembled, the insert 20a can be directly knocked out of the mounting hole 12a, and high-temperature sealant or high-temperature industrial repair agent at the edge of the mounting hole 12a is cleaned, so that another insert can be conveniently replaced.
And (3) a third sealing method: the sealing material is a combination of a high-temperature silica gel sealing strip and a high-temperature sealing gum. Referring to fig. 3, another insert structure of this embodiment 2 is shown, a circle of groove a is formed on an edge of an insert 20a, a high-temperature silicone rubber sealing strip is placed in the groove a, and then, according to a second sealing method, a high-temperature sealing glue is coated on an edge of a mounting matching surface between the insert 20a and a mounting hole 12a, and then the insert 20a is respectively inserted into the mounting hole 12a, so that a gap between the insert 20a and the mounting hole 12a is completely filled, and an excess portion is removed. The disassembly is similar to the sealing method II.
