However, this device places the cooling pipes inside the mold, and there is no corresponding cooling structure on the outside of the mold, which cannot guarantee a constant temperature and rate during the overall cooling process of the mold, and the overall cooling time is relatively long. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a constant-temperature and constant-speed oil-cooling mold device that works in conjunction with an internal oil-cooling pipe in the mold to ensure constant temperature and speed during the cooling process and accelerate the cooling time.

[0004] The objective of this invention is achieved through the following technical solution: A constant-temperature and constant-speed oil-cooled mold device includes a fixed mold base plate, a fixed frame plate, a side rotating baffle, an upper rotating baffle, a rotating corner plate, a first rotating shaft, a fixed push rod, a U-shaped push plate, a limiting bar, a cylinder, and a cooling oil spray pipe. The fixed frame plate has a side connecting frame, the fixed mold base plate is adapted to the side connecting frame, the fixed mold base plate is inserted into the side connecting frame, the side connecting frame is connected to the fixed mold base plate by bolts, the side rotating baffle is connected to the fixed frame plate by hinges, a set of side rotating baffles are symmetrically arranged on the side of the fixed frame plate, the upper rotating baffle is connected to the fixed frame plate by hinges, the right side of the fixed frame plate has a side baffle, the cooling oil spray pipe is installed inside the fixed frame plate, multiple nozzles are installed inside the cooling oil spray pipe, the upper part of the cooling oil spray pipe is connected to the cooling oil external pipe, the lower part of the fixed frame plate has a cooling oil discharge pipe, the cooling oil discharge pipe is connected to the recovery pipe.

[0005] The first connecting ear is connected to the side rotating baffle. The side of the rotating corner plate is in contact with the first connecting ear. The rotating corner plate is connected to a set of first connecting ears through the first rotating shaft. The rotating corner plate is connected to the side rotating baffle and the upper rotating baffle in the same way. The second connecting ear is connected to the fixed frame plate. The side of the rotating corner plate is in contact with the second connecting ear. The rotating corner plate is connected to a set of second connecting ears through the second rotating shaft.

[0006] The U-shaped push plate is fitted onto the fixed frame plate, the limiting bar is connected to the fixed frame plate, the limiting bar is inserted into the U-shaped push plate, the limiting bar slides inside the U-shaped push plate, the limiting bar is symmetrically arranged on both sides of the fixed frame plate, the lower part of the cylinder is connected to the fixed frame plate by bolts, and the cylinder piston rod is connected to the U-shaped push plate.

[0007] The rotating angle plate has a strip-shaped sliding hole. The fixed push rod is adapted to the strip-shaped sliding hole. The fixed push rod is inserted into the strip-shaped sliding hole and slides in the strip-shaped sliding hole. The fixed push rod is connected to a limiting ball. The limiting ball is in contact with the rotating angle plate. A set of limiting balls are distributed on both sides of the strip-shaped sliding hole. The fixed push rod is connected to a circular connecting plate. The circular connecting plate is connected to a U-shaped push plate by bolts. Beneficial effects

[0008] 1. The side connecting frame of this invention is bolted to the fixed mold base plate, so that the fixed frame plate is installed and fixed on the fixed mold end of the mold. Cooling oil spray pipe is installed inside the fixed frame plate. The cooling oil spray pipe sprays cooling oil into the fixed frame plate at a constant speed through multiple installed nozzles. After the fixed mold and moving mold are closed and injection is completed, cooling oil is sprayed onto the mold surface at a constant speed during the cooling time to accelerate the cooling time of the mold. The cooling time can be easily adjusted to maintain a constant temperature through the cooling oil. The cooling oil enters the cooling oil spray pipe through the cooling oil external pipe. The right side of the fixed frame plate has a side baffle. The side baffle prevents the cooling oil from spilling out from the side of the fixed frame plate during the use of the oil-cooled mold. The cooling oil dripping from the mold falls into the bottom of the fixed frame plate and is collected and filtered out through the cooling oil discharge pipe for reuse. The side rotating baffle and the upper rotating baffle are connected to the fixed frame plate by hinges. The side rotating baffle and the upper rotating baffle are designed to be rotatable. When the cooling oil is sprayed onto the mold, it blocks the cooling oil from splashing out from the gap between the fixed frame plate and the mold during the use of the oil-cooled mold.

[0009] 2. In this invention, the rotating angle plate is shaft-connected to the side rotating baffle, and the rotating angle plate is shaft-connected to the fixed frame plate. The rotation of the side rotating baffle is controlled by the rotatable structure of the rotating angle plate. The side rotating baffle and the upper rotating baffle are each connected to the fixed frame plate through the rotating angle plate, and the connection method is the same. The fixed push rod is fixed to the U-shaped push plate through a circular connecting plate. The movement of the U-shaped push plate controls the simultaneous movement of the three fixed push rods. The limiting bars are fixed to the side of the fixed frame plate. The U-shaped push plate is limited by the symmetrical limiting bars, preventing the U-shaped push plate from being pushed during the use of oil-cooled molds. The plate falls from the fixed frame, causing the U-shaped push plate to slide horizontally. A set of limiting balls are fixed on the fixed push rod, and another set of limiting balls are distributed on both sides of the strip-shaped sliding hole to apply a pushing and pulling force to the rotating corner plate. The movement of the U-shaped push plate drives the fixed push rod to move, which in turn pushes and pulls the rotating corner plate, causing it to rotate. This, in turn, drives the rotation of the side rotating baffle. The cylinder is installed and fixed on the fixed frame. When the cylinder works, it drives the U-shaped push plate to move, thereby controlling the simultaneous rotation of the symmetrical side rotating baffle and the upper rotating baffle to ensure the collection and splash prevention of cooling oil.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A constant-temperature and constant-speed oil-cooled mold device includes a fixed mold base plate 01, a fixed frame plate 02, a side rotating baffle 05, an upper rotating baffle 06, a rotating angle plate 07, a first rotating shaft 09, a fixed push rod 11, a U-shaped push plate 16, a limiting bar 17, a cylinder 18, and a cooling oil spray pipe 20. The fixed frame plate 02 has a side connecting frame 03. The fixed mold base plate 01 is adapted to the side connecting frame 03. The fixed mold base plate 01 is inserted into the side connecting frame 03. The side connecting frame 03 is connected to the fixed mold base plate 01 by bolts, so that the fixed frame... Plate 02 is fixed to the fixed mold end of the mold. Side rotating baffles 05 are connected to the fixed frame plate 02 via hinges. A set of side rotating baffles 05 are symmetrically arranged on the side of the fixed frame plate 02. Upper rotating baffles 06 are connected to the fixed frame plate 02 via hinges. The side rotating baffles 05 and upper rotating baffles 06 are respectively connected to the fixed frame plate 02 via hinges. The side rotating baffles 05 and upper rotating baffles 06 are designed to be rotatable. When cooling oil is sprayed onto the mold, this is to prevent cooling oil from flowing from the fixed frame plate 02 to the mold during oil-cooled mold use. The gaps between the mold plates prevent the cooling oil from splashing out and thus block it. The right side of the fixed frame plate 02 has a side baffle 04. A cooling oil spray pipe 20 is installed inside the fixed frame plate 02, with multiple nozzles installed inside. The cooling oil spray pipe 20 sprays cooling oil at a constant speed into the fixed frame plate 02 through these multiple nozzles. After the fixed and moving molds are closed and injection molding is completed, cooling oil is sprayed at a constant speed onto the mold surface during the cooling time to accelerate the mold's cooling process. The cooling oil spray pipe 20... The part is connected to the external cooling oil pipe 19. The lower part of the fixed frame plate 02 has a cooling oil discharge pipe 21, which is connected to the recovery pipe. Cooling oil enters the cooling oil spray pipe 20 through the external cooling oil pipe 19. The right side of the fixed frame plate 02 has a side baffle 04. The side baffle 04 prevents the cooling oil from spilling from the side of the fixed frame plate 02 during the use of the oil-cooled mold, so that the cooling oil dripping from the mold falls into the bottom of the fixed frame plate 02 and is collected and filtered outward through the cooling oil discharge pipe 21 for secondary use. This invention achieves coordinated constant temperature and speed oil cooling inside and outside the mold using a fixed frame plate 02 and a cooling oil spray pipe 20. Combined with a cylinder 18, a U-shaped push plate 16, and a rotating corner plate 07 linked baffle anti-splash mechanism, it not only achieves basic cooling acceleration, oil splash prevention, and medium circulation, but also brings multiple unexpected efficiency benefits through flexible transmission via connecting rod sliding holes, a sealed heat exchange chamber, and a modular external design. These benefits include improved temperature stability, extended mechanism life, reduced equipment energy consumption, and mold universalization upgrades. It balances cooling precision, equipment durability, and production economy, effectively solving the pain points of uneven cooling, low efficiency, and high maintenance costs of existing oil-cooled molds.

[0016] Example 2: The first connecting ear 08 of the present invention is connected to the side rotating baffle 05. The side of the rotating corner plate 07 is in contact with the first connecting ear 08. The rotating corner plate 07 is connected to a set of first connecting ears 08 through a first rotating shaft 09. The rotating corner plate 07 is connected to the side rotating baffle 05 and the upper rotating baffle 06 in the same way. The second connecting ear 12 is connected to the fixed frame plate 02. The side of the rotating corner plate 07 is in contact with the second connecting ear 12. The rotating corner plate 07 is connected to a set of second connecting ears 12 through a second rotating shaft 13. The rotating corner plate 07 is axially connected to the fixed frame plate 02. The rotation of the side rotating baffle 05 is controlled by the rotatable structure of the rotating corner plate 07. The side rotating baffle 05 and the upper rotating baffle 06 are each connected to the fixed frame plate 02 through the rotating corner plate 07 in the same way.

[0017] Example 3: The U-shaped push plate 16 of the present invention is sleeved on the fixed frame plate 02. The limiting bar 17 is connected to the fixed frame plate 02 and inserted into the U-shaped push plate 16. The limiting bar 17 slides inside the U-shaped push plate 16. The limiting bar 17 is symmetrically arranged on both sides of the fixed frame plate 02 and fixed to the side of the fixed frame plate 02. The U-shaped push plate 16 is limited by the symmetrical limiting bar 17, which prevents the U-shaped push plate 16 from falling off the fixed frame plate 02 during the use of the oil-cooled mold and allows the U-shaped push plate 16 to slide horizontally. The lower part of the cylinder 18 is connected to the fixed frame plate 02 by bolts, and the piston rod of the cylinder 18 is connected to the U-shaped push plate 16.

[0018] Example 4: The rotating angle plate 07 of the present invention has a strip-shaped sliding hole 10. A fixed push rod 11 is adapted to the strip-shaped sliding hole 10 and is inserted into the strip-shaped sliding hole 10. The fixed push rod 11 slides within the strip-shaped sliding hole 10. The fixed push rod 11 is connected to a limiting ball 15, which fits against the rotating angle plate 07. A set of limiting balls 15 are distributed on both sides of the strip-shaped sliding hole 10. The fixed push rod 11 is connected to a circular connecting plate 22. The circular connecting plate 22 is connected to a U-shaped push plate 16 by bolts. The fixed push rod 11 is fixed to the U-shaped push plate 16 by the circular connecting plate 22. The movement of the U-shaped push plate 16 controls the simultaneous movement of the three fixed push rods 11. A set of limiting balls 15 are fixed to the fixed push rod 11. Body 15 is distributed on both sides of the strip-shaped sliding hole 10 to apply a pushing and pulling force to the rotating corner plate 07. The U-shaped push plate 16 moves, driving the fixed push rod 11 to move, thereby pushing and pulling the rotating corner plate 07, causing the rotating corner plate 07 to rotate, which in turn drives the side rotating baffle 05 to rotate. Cylinder 18 is installed and fixed on the fixed frame plate 02. When cylinder 18 works, it drives the U-shaped push plate 16 to move, thereby controlling the simultaneous rotation of the symmetrical side rotating baffle 05 and the upper rotating baffle 06, ensuring the collection and splash prevention of cooling oil. This device is used in conjunction with the oil cooling pipe inside the mold to spray cooling oil at a constant speed and to easily adjust the cooling time to maintain a constant temperature, so that the mold can maintain a constant temperature and speed during the cooling process, thus improving the working efficiency of the mold.

On 02, insert the limiting bar 17 into the U-shaped push plate 16, connect the limiting bar 17 to the fixed frame plate 02, connect the cylinder 18 to the fixed frame plate 02, connect the piston rod of the cylinder 18 to the U-shaped push plate 16, install the cooling oil spray pipe 20 inside the fixed frame plate 02, pass the cooling oil outer pipe 19 through the fixed frame plate 02 and connect the cooling oil spray pipe 20, connect the side rotating baffle 05 to the fixed frame plate 02 through a hinge, and connect the upper rotating baffle 06 to the fixed frame plate 02 through a hinge.
