[0014] A method for connecting a die-casting mold with high die-casting efficiency, the method comprising the following steps: Step A: First, the output end is pushed out by the electric telescopic cylinder to make the sliding plate slide toward the front plate, so that the first mold and the second mold are closely attached to each other. Then, the molten metal is transported to the position of the liquid inlet funnel through the conveying pipe through the storage tank, and the molten metal is poured into the inside of the liquid injection pipe through the liquid inlet funnel. At this time, the output end is pushed out by the electric push rod to drive the inclined block and the sealing head to move toward the liquid injection hole, so that the sealing head and the inclined block drive the molten metal to flow from the inside of the liquid injection hole into the inside of the molding cavity, and high pressure is applied to it. At this time, the sealing head will block the liquid injection hole, so that the molten metal cannot flow back to the inside of the liquid injection pipe through the liquid injection hole; Step B: coolant is transported to the inside of the cooling pipe and the cooling channel through the cooling table to cool the first mold and the second mold, and then the molten metal is cooled and shaped inside the molding cavity, and then the output end is retracted by the electric telescopic cylinder to drive the sliding plate to move in the direction of the connecting rod, so that the first mold and the second mold are separated. At this time, since the L-shaped matching block follows the first mold to move in the direction of the connecting rod, it drives the die-casting formed in the molding cavity to move together. When the first mold and the second mold are separated, the trapezoidal matching block will move out from the inside of the sliding trough. At this time, the die-casting will slide down through the inclined surface of the sliding trough and fall into the inside of the discharge port, so that the die-casting is collected and pushed out by the electric telescopic cylinder to drive the output end to slide the sliding plate in the direction of the front plate, so that the first mold and the second mold are closely attached, so that the device can perform continuous die-casting processing; Step C: When it is necessary to produce die-castings of different shapes, the four limiting rods can be pulled outward so that the limiting rods no longer limit the first mold, so that the first mold can be pulled out from the front side of the cooling table, and the second mold can be separated from the front plate by removing the bolts, so that the first mold and the second mold can be replaced. When the new first mold is inserted into the interior of the cooling table, the limiting rods are loosened, and the limiting rods are driven by the elastic potential energy of the compression spring to move in the direction of the limiting slot, so that the limiting rods are inserted into the interior of the limiting slot, and then the first mold is fixed and limited, so that the device can conveniently replace the first mold and the second mold according to needs, so as to produce die-castings of different shapes; Step D: Through the cooperation of the cooling pipe and the cooling channel, the molten metal can be cooled faster through the cooling channel. At the same time, the cooling pipe wraps the second mold inside, so that the cooling pipe can accelerate the cooling of the molten metal located inside the second mold, thereby avoiding the output of defective products due to uneven cooling of the molten metal.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cooperates with the trapezoidal matching block and the L-shaped matching block so that when the device is stripping, the L-shaped matching block will drive the die-casting to move with the first mold to avoid the die-casting remaining inside the second mold. When the first mold and the second mold are completely separated, the trapezoidal matching block no longer blocks the die-casting. At this time, the die-casting will slide down due to gravity and the inclined surface of the sliding trough, thereby realizing automatic stripping and avoiding the situation where the die-casting is stuck in the second mold and cannot fall out and requires manual intervention.

[0016] 2. The present invention cooperates with the cooling pipe and the cooling channel so that when the device cools the molten metal, the cooling efficiency of the molten metal can be improved through the cooling pipe and the cooling channel. The molten metal located in the first mold is cooled by the cooling channel, and the molten metal located in the second mold is cooled by the cooling pipe, thereby avoiding the situation where half of the mold is cooled and the other half is not cooled, thereby reducing the output of defective products.

The die-casting formed in the molding cavity 211 is moved together with it. When the first mold 203 and the second mold 204 are separated, the trapezoidal matching block 213 will move out from the inside of the slide groove 212. At this time, the die-casting will slide downward through the inclined surface of the slide groove 212 and fall into the inside of the discharge port 108, so that the die-casting is collected and pushed out by the output end driven by the electric telescopic cylinder 105, so that the sliding plate 201 slides in the direction of the front plate 102, so that the first mold 203 and the second mold 204 are closely attached, so that the device can perform continuous die-casting processing; Step C: When it is necessary to produce die-castings of different shapes, the four limiting rods 206 can be pulled outward so that the limiting rods 206 no longer limit the first mold 203, so that the first mold 203 can be pulled out from the front side of the cooling table 202, and the second mold 204 can be separated from the front plate 102 by removing the bolts, so that the first mold 203 and the second mold 204 can be replaced. When the new first mold 203 is inserted into the interior of the cooling table 202, the limiting rod 206 is loosened, and the limiting rod 206 is driven by the elastic potential energy of the compression spring 208 to move in the direction of the limiting slot 210, so that the limiting rod 206 is inserted into the interior of the limiting slot 210, and then the first mold 203 is fixed and limited, so that the device can conveniently replace the first mold 203 and the second mold 204 according to needs, so as to produce die-castings of different shapes; Step D: Through the cooperation of the cooling pipe 205 and the cooling channel 215, the molten metal can be cooled faster through the cooling channel 215. At the same time, the cooling pipe 205 wraps the second mold 204 inside, so that the cooling pipe 205 can accelerate the cooling of the molten metal located inside the second mold 204, thereby avoiding the output of defective products due to uneven cooling of the molten metal.

The die-casting mold with high connection die-casting efficiency according to claim 4, characterized in that: The first mold (203) is movably inserted into the interior of the front side surface of the cooling platform (202), and the second mold (204) is connected to the front plate (102) via bolts.

10. A die-casting mold with high connection die-casting efficiency and a method for using the same according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: Step A: First, the output end is pushed out by the electric telescopic cylinder (105), so that the sliding plate (201) slides in the direction of the front plate (102), so that the first mold (203) and the second mold (204) are closely attached to each other, and then the molten metal is transported to the position of the liquid inlet funnel (306) through the storage tank (6) through the delivery pipe (4), and the molten metal is poured into the interior of the liquid injection pipe (302) through the liquid inlet funnel (306). At this time, the electric push rod (301) The driving output end is pushed out, so that it drives the inclined block (305) and the sealing head (303) to move in the direction of the injection hole (216), so that the sealing head (303) and the inclined block (305) drive the molten metal to flow from the inside of the injection hole (216) into the inside of the molding cavity (211), and a high pressure is applied thereto. At this time, the sealing head (303) blocks the injection hole (216), so that the molten metal cannot flow back to the inside of the injection tube (302) through the injection hole (216); Step B: Cooling liquid is transported to the interior of the cooling pipe (205) and the cooling channel (215) through the cooling table (202) so as to cool the first mold (203) and the second mold (204), thereby cooling the molten metal so as to be cooled and shaped inside the molding cavity (211). Subsequently, the output end is driven to be retracted through the electric telescopic cylinder (105) so as to drive the sliding plate (201) to move in the direction of the connecting rod (104), so as to separate the first mold (203) and the second mold (204). At this time, the L-shaped matching block (214) follows the first mold (203) to move in the direction of the connecting rod (104). , so that it drives the die-casting formed inside the molding cavity (211) to move together, when the first mold (203) and the second mold (204) are separated, the ladder-shaped matching block (213) will move out from the inside of the slide groove (212), and the die-casting will slide downward through the inclined surface of the slide groove (212) and fall into the inside of the discharge port (108), so that the die-casting is collected and pushed out by driving the output end through the electric telescopic cylinder (105), so that the sliding plate (201) slides in the direction of the front plate (102), so that the first mold (203) and the second mold (204) are closely attached, so that the device can perform continuous die-casting processing; Step C: When it is necessary to produce a die-casting of a different shape, the four limiting rods (206) can be pulled outward so that the limiting rods (206) no longer limit the first mold (203), so that the first mold (203) can be pulled out from the front side of the cooling table (202), and the second mold (204) can be separated from the front plate (102) by removing the bolts, so that the first mold (203) and the second mold (204) can be replaced. When the new first mold (203) is inserted After entering the interior of the cooling table (202), the limiting rod (206) is loosened, and the limiting rod (206) is driven by the elastic potential energy of the compression spring (208) to move in the direction of the limiting slot (210), so that the limiting rod (206) is inserted into the interior of the limiting slot (210), thereby fixing the first mold (203), so that the device can conveniently replace the first mold (203) and the second mold (204) according to needs, so as to produce die-casting parts of different shapes; Step D: By cooperating with the cooling pipe (205) and the cooling channel (215), the molten metal can be cooled faster through the cooling channel (215). At the same time, the cooling pipe (205) wraps the second mold (204) inside, so that the cooling pipe (205) can accelerate the cooling of the molten metal located inside the second mold (204), thereby avoiding the production of defective products due to uneven cooling of the molten metal.
