Description

Technical Field

[0001] This utility model relates to the field of zinc alloy block die casting mold technology, and in particular to a die casting mold for zinc alloy block production. Background Technology

[0002] Die-casting molds for zinc alloy block production are used to enable zinc alloy blocks to obtain the required shape, size and precision. By rationally designing the cavity, core and other structures of the mold, zinc alloy blocks of various complex shapes can be produced. During the die-casting process, liquid zinc alloy is rapidly filled under high pressure. The die-casting mold can complete the molding process in a short time, which greatly improves production efficiency and can be reused for a long time.

[0003] For example, CN213410250U discloses an aluminum-zinc alloy ingot casting mold, comprising a base plate, an electric telescopic rod fixedly connected to the upper surface of the base plate, a cooling box fixedly connected to the telescopic end of the electric telescopic rod, and cooling water stored inside the cooling box; two first inverted L-shaped plates fixedly connected to the upper surface of the base plate, a lower mold fixedly connected to the opposite surfaces of the two first inverted L-shaped plates; a T-shaped slider slidably connected to the upper surface of the base plate, and a second inverted L-shaped plate fixedly connected to the upper surface of the T-shaped slider. This aluminum-zinc alloy ingot casting mold, by setting up a preheating hopper, a preheating layer, a heating element, and a feeding pipe, allows the heating element to raise the temperature inside the preheating hopper after being powered on, facilitating the preheating of the aluminum-zinc alloy casting liquid in the preheating hopper. This allows the aluminum-zinc alloy casting liquid to be better cast and shaped between the upper and lower molds, improving the processing quality of the shaped product and facilitating the subsequent demolding process.

[0004] While common die-casting molds used in zinc alloy block production can dissipate heat from the zinc alloy block within the mold using coolant, the coolant is not in a flowing state, resulting in poor heat dissipation and difficulty in quickly cooling the zinc alloy block, thus reducing cooling efficiency. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a die-casting mold for producing zinc alloy blocks, which can quickly cool the zinc alloy blocks in the mold.

[0006] The technical solution adopted by this utility model is as follows: It includes a mounting base, a lower mold fixedly mounted at the middle of the upper end of the mounting base, an L-shaped plate fixedly mounted on one side of the upper end of the mounting base, a cylinder fixedly mounted at one end of the L-shaped plate, an upper mold fixedly mounted at the output end of the cylinder, a feed pipe fixedly mounted at one end of the mounting base, and one end of the feed pipe connected to the lower mold. The mounting base has annular cavities arranged in a linear array inside. A square plate is fixedly mounted at one end of the mounting base inside. Liquid storage cavities are arranged in a left-right distribution inside the square plate and are connected to the annular cavities.

In use, the cooling component is used to rapidly cool the coolant. Several annular cavities are provided. The feed pipe is used to deliver liquid zinc alloy into the lower mold. The cylinder is used to move the upper mold up and down.

[0007] Preferably, in order to separate the liquid storage chamber, the liquid storage chamber is equipped with partitions arranged in a linear array inside.

[0008] Preferably, in order to connect the liquid storage cavity with the annular cavity, the square plate has circular holes arranged in a linear array at both ends, one end of the circular holes is connected to the liquid storage cavity, and the other end of the circular holes is connected to the annular cavity.

[0009] Preferably, in order to deliver coolant into the liquid storage chamber, the cooling assembly includes an inlet pipe, an outlet pipe, a loop-shaped cooling pipe, and a water pump. The water pump is fixedly installed in the circular cavity. One end of the inlet pipe is fixedly connected to the square plate and extends into the liquid storage chamber. The other end of the inlet pipe is fixedly connected to the water pump, and the other end of the water pump is fixedly connected to the loop-shaped cooling pipe.

[0010] Preferably, in order to increase the heat dissipation area, the first cooling pipes are installed in a linear array on the inner side of the U-shaped cooling pipes.

[0011] Preferably, in order to discharge the coolant inside the storage chamber, one end of the outlet pipe is fixedly connected to the square plate, and one end of the outlet pipe extends into the storage chamber, while the other end of the outlet pipe is fixedly connected to the U-shaped cooling pipe.

A cold air fan is fixedly installed on one side of the mounting base, and an air supply pipe is fixedly installed at the output end of the cold air fan. One end of the air supply pipe is fixedly connected to the air outlet plate, and the cold air fan is used to generate cold air.

[0013] Preferably, in order to control the air cooler and the water pump, a control panel is fixedly installed on one side of the mounting base. The air cooler and the water pump are electrically connected to the control panel. The control panel is equipped with a controller for controlling the air cooler.

[0014] The beneficial effects of this utility model are as follows: When in use, this utility model uses a water pump to deliver flowing coolant into the annular cavity to quickly cool and dissipate heat from the zinc alloy block in the lower mold, resulting in good cooling effect. At the same time, by uniformly delivering cold air to the U-shaped cooling pipe and the first cooling pipe, the coolant is rapidly cooled, thereby improving the cooling efficiency of the zinc alloy block.

A square plate 6 is fixedly mounted on one end of the mounting base 1. Liquid storage containers are distributed left and right inside the square plate 6. The liquid storage chamber 7 is connected to the annular cavity 5. A circular cavity 8 is formed at the bottom of the mounting base 1, and a cooling assembly 9 is installed inside the circular cavity 8. One end of the cooling assembly 9 is connected to a square plate 6. Baffles 10 are arranged in a linear array inside the liquid storage chamber 7. Circular holes 11 are arranged in a linear array at both ends of the square plate 6. One end of each circular hole 11 is connected to the liquid storage chamber 7, and the other end is connected to the annular cavity 5. During operation, liquid zinc alloy is first transported to the lower mold 2 through the feed pipe 4. Then, the cylinder is activated to move the upper mold 3 downwards for mold closing. When cooling is required, the cooling assembly 9 transports flowing coolant to the liquid storage chamber 7 inside the square plate 6, and then through the circular holes 11 to the annular cavity 5, rapidly cooling the zinc alloy block in the lower mold 2. This provides good cooling effect and simultaneously rapidly cools the coolant, thereby improving the cooling efficiency of the zinc alloy block.

First, the water pump 904 is manually started through the control panel 12 to deliver coolant through the liquid inlet pipe 901 to the liquid storage chamber 7 inside the square plate 6, and then through the circular hole 11. The liquid is sent into the annular cavity 5 to rapidly cool the zinc alloy block. Then, it is transported through the circular hole 11 to the liquid storage chamber 7 on the other side. Next, it is transported through the liquid outlet pipe 902 to the loop cooling pipe 903 and the first cooling pipe 905. Then, the cooler 908 is manually started through the control panel 12. The generated cool air is transported through the air duct 909 to the air outlet slot 907 at one end of the air outlet plate 906 to rapidly cool the coolant, thereby improving the cooling efficiency of the zinc alloy block. The hot air is discharged through the air outlet.
