Abstract

DC60 (20/04/54) Mold cooling water pipe consists of a hollow inner fluid delivery pipe with open ends. A protective tube is fitted to the outer surface to prevent fluid leakage when the front open end of the fluid delivery pipe is inserted into a hole in the mold. The inside of the fluid delivery pipe has a longitudinal baffle dividing it into an outlet and a return fluid pipe. A rear end cap is attached to the open rear end of the fluid delivery pipe. This cap has an open end on one side for fitting onto the rear open end of the fluid delivery pipe. Part of the rear cap is an inlet fluid pipe with an internal channel for fluid entry connecting to the outlet fluid pipe, accommodating an external fluid entry connection. The other part of the rear cap is a return fluid pipe with an internal channel for fluid return connecting to the return fluid pipe, accommodating an external fluid return connection. Both ends are open, with a protective tube fitted to a portion of the outer surface to prevent liquid from flowing out when the front open end of the liquid delivery pipe is inserted into a hole in the mold. The inside of the liquid delivery pipe has a longitudinal baffle dividing it into an outlet and a return liquid pipe. A rear end cap is attached to the open rear end of the liquid delivery pipe. This rear end cap has an open end on one side for fitting onto the rear open end of the liquid delivery pipe. Part of the rear end cap is a liquid inlet pipe with an internal liquid inlet channel connecting to the liquid outlet pipe to accommodate an external liquid inlet connection. The other part of the rear end cap is a liquid return pipe with an internal liquid return channel connecting to the return pipe to accommodate an external liquid return connection.

Claims (5)

1. The mold cooling tube consists of a fluid delivery tube (1) which is a hollow tube with open ends for delivering fluid from one open end to the other. On the outer surface at or towards the front end of the fluid delivery tube (1), there is a fluid barrier tube (2) which is a rubber or silicone tube fitted to prevent water from flowing out when the open front end of the fluid delivery tube (1) is inserted into any hole in the mold. On the outer surface of the fluid barrier tube (2), there is a raised shoulder (3) to prevent the fluid barrier tube (2) from sliding out when inserted into any hole in the mold. On the front and back of the fluid barrier tube (2), there are locking rings (4) fitted to the outer surface of the fluid delivery tube (1) to prevent the fluid barrier tube (2) from sliding out of the fluid delivery tube (1). It has a special characteristic: Inside the liquid delivery pipe (1) there is an inner divider (5) which is a divider or inner divider base along the length of the liquid delivery pipe (1) to divide the inside of the liquid delivery pipe (1) into an outlet pipe (6) and a return pipe (7), and at the open rear end of the liquid delivery pipe (1) there is a rear pipe cap (8) installed, which is a structure with one end open for fitting onto the open rear end of the liquid delivery pipe (1), and part of the rear pipe cap (8) is the liquid inlet pipe (9), which is a pipe with an inner liquid inlet channel (10) that connects to the liquid outlet pipe (6) to accommodate the connection from the external liquid inlet pipe to allow liquid from the outside to flow in through the liquid inlet channel (10) through the liquid outlet pipe (6) to cool the mold. The open front end of the fluid delivery pipe (1) and the other end of the closed rear pipe base (8) are connected to the fluid return pipe (12), which is a tube with an inner fluid return channel (13) that connects to the fluid return pipe (7) to accommodate the connection of an external fluid return pipe to draw the mold cooling fluid back into the fluid return pipe (7) and through the fluid return channel (13). 2. The coolant pipe for the mold, as per claim 1, the outer surface of the liquid delivery pipe (9) shall be a level shoulder at the inlet (11) to prevent the liquid delivery pipe from slipping out when fitted onto the outside of the liquid delivery pipe (9). 3. For any of the mold cooling pipes under any of the claims 1-2, the outer surface of the return fluid delivery pipe (12) shall be a return shoulder (14) to prevent the return fluid suction pipe from slipping out when fitted onto the outer surface of the return fluid delivery pipe (12). 4. The cooling water pipes for any of the claims 1-3, in the area of some of the voids inside the rear pipe base (8), shall be sealed with an external adhesive or binder for the purpose of separating and separating the fluids being sent from the fluid inlet port (10) to the fluid outlet pipe (6) from the fluids being sent from the fluid return pipe (7) to the fluid return port (13). 5. The cooling pipe for the mold under any of the claims 1-4 shall have a rear support tube (15) of the rubber or silicone rubber type fitted to the outer surface of the liquid delivery pipe (1) in front of the rear pipe end base (8) to help support the liquid delivery pipe (1) so that it does not bend and break.
