Embodiment Construction
[0019] refer to Figure 1 to Figure 4 , the present invention is an installation structure for preventing core fracture and running aluminum with point cooling, including a mold 8 and a point water carrier installed on the mold 8, and the point water carrier includes a transition from the outside to the inside nested layer by layer Screw 3, point transport pipe 4 and water pipe 5. The shape of the transition screw 3 is similar to that of a standard screw, with a nut and a shaft. A through hole is further processed inside the transition screw 3. At the same time, the transition screw 3 can be provided with a small thread on the head. The point water delivery device also includes a cooling head 6 installed on the inside of the mold 8. The inside of the cooling head 6 has a stepped hole. The outer wall is threaded with mold 8, the large diameter end of the stepped hole is threaded with the head of the transition screw 3, the small diameter end of the stepped hole encloses the he...

The present invention discloses an installation structure for preventing a mold core with a point cooling head from fracturing and causing aluminum leakage. The installation structure comprises a moldand a point water conveyer, wherein the point water conveyer comprises transition screws, point water conveying pipes and water delivery pipes which are nested layer by layer from outside to inside;the minimum clearance dimension between the transition screws and the mold and the minimum clearance dimension between the transition screws and the point water conveying pipes are both less than 0.5mm; the mold is provided with fastening nuts at the nuts of the transition screws; the outer walls of the fastening nuts are in threaded connection with the inner wall of the mold; the partial outer walls of the point water conveying pipes are bulged to form a first stepped shaft; the first stepped shaft is in threaded connection with the inner walls of the transition screws. When the point cooling head fractures, a gap with a size of less than 0.5 mm can effectively prevent molten aluminum from overflowing; at the same time, the solution of the present invention has the function of double protection, the gap between the mold and the point water conveyer is blocked by the fastening nuts at the end, and the gap between the transition screws and the point water conveying pipes is also blocked by the first stepped shaft at the end. The installation structure of the present invention is applied to the field of mold casting.
Description
technical field [0001] The invention relates to the field of mold casting, in particular to an installation structure for preventing mold core from breaking and running out of aluminum with some coldness. Background technique [0002] Mold casting needs to inject molten aluminum into the cavity. Due to the complex internal structure of the mold and the different flow times of the molten aluminum in the cavity, different positions in the cavity may have different cooling rates; at this time, in order to ensure that the overall cooling rate of the cavity is uniform, it is necessary to do certain parts. special treatment. This special treatment refers to cooling, and a cooling head is set on the inner surface of the mold. At this time, the cooling head is fixedly installed and used as a part of the core. The outside world flows into the inside of the cooling head, and the temperature of the cooling head is low. At this time, tap the cold head to reduce the temperature of the ...
