[0002] In the process of manufacturing automobile parts, molds are needed. Equipment used to manufacture parts or products with specific shapes and sizes is called molds.

[0003] For example, the patent document with the publication number CN211441028U discloses an injection mold that is convenient for cooling injection molding materials, including an injection mold, a mold cover and a micro water pump, wherein the mold cover is arranged above the injection mold, and a water storage cavity is arranged inside the injection mold, a heat sink is arranged inside the water storage cavity, and the heat sink is connected to the injection mold, and a heat sink is arranged on the heat sink, a second cover is installed above the first cover, and a cooling tube body is installed below the first cover, and the cooling tube body is located on the inner side of the water storage tank, a micro water pump is arranged on the left side of the water storage tank, and the micro water pump is connected to the water injection pipe. The injection mold that is convenient for cooling injection molding materials is convenient for the injection of cooling liquid by arranging a water storage cavity inside the injection mold, and a heat sink and a heat sink are arranged in the water storage cavity, so as to facilitate the rapid conduction of heat in the cavity, thereby facilitating the circulating coolant to take away the heat on the heat sink and the heat sink, thereby improving the cooling efficiency.

[0004] When the above device is used, the liquid material is first injected into the cavity on the injection mold, and then the mold cover is covered, and then coolant is added to the water tank. After the coolant is added to the water tank, the first cover plate is covered on the water tank. As shown in the figure, liquid nitrogen is added to the cavity on the first cover plate, and the liquid nitrogen added to the cavity flows into the cooling tube body. After the liquid nitrogen is added, the second cover plate is covered on the first cover plate to seal the cavity, and then the micro water pump is started. At this time, the micro water pump extracts the coolant in the water tank, and the extracted coolant is injected into the water storage cavity through the water injection pipe, and the heat dissipation block in the water storage cavity guides the heat in the injection mold cavity. However, it is unclear where the demoulding mechanism of the product is set, and manual demoulding is required, and the process is relatively cumbersome. For this reason, we propose a mold with a reverse top. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 1-3 As shown, a mold with an inverted top includes a base 1;

[0022] The mounting frame 2 is arranged on both sides of the top of the base 1 and has a receiving space 201;

[0023] The electric push rod 3 is arranged at the top of the accommodation space 201 and is fixedly connected to the mounting frame 2;

[0024] The movable mold 4 is arranged at the bottom of the electric push rod 3, a convex block is arranged at the bottom and a feed port is arranged on the movable mold 4;

[0025] The fixed mold 5 is arranged on the top of the base 1. A groove is provided on the fixed mold 5, which overlaps with the convex block provided on the movable mold 4 to form an injection molding wall cavity;

[0026] The ejector assembly 6 is disposed at the top of the accommodating space 201 and the output end thereof is located inside the movable mold 4 .

[0027] The staff starts the electric push rod 3 to lift it downward, and the electric push rod 3 drives the movable mold 4 at the bottom to move downward so that the bottom protrusion moves into the groove with the fixed mold 5 to form an injection cavity, and then transports the material to the injection cavity through the feed port for processing. After the product processing is completed, the staff starts the electric push rod 3 to retract upward, and then drives the movable mold 4 to move upward. As the movable mold 4 moves upward, the bottom end of the ejector rod 601 ejects the movable mold 4, thereby pushing the bottom product down for unloading. The device is convenient for ejecting products and unloading by setting an ejection mechanism.

[0028] like Figure 1 and Figure 2 As shown, the ejector assembly 6 includes a push rod 601 and a spring 602 . The top of the push rod 601 is fixedly mounted on the mounting frame 2 and two push rods 601 are symmetrically arranged about the center line of the movable mold 4 perpendicular to the ground. The spring 602 is arranged on the push rod 601 .

[0029] When the electric push rod 3 drives the movable mold 4 to move upward, the movable mold 4 is buffered by the limit block on the ejector rod 601 squeezing the spring 602, so that the bottom end of the ejector rod 601 is pushed out of the movable mold 4, thereby pushing the product at the bottom of the movable mold 4 down.

[0030] like Figure 1 As shown, a mounting cavity 101 is provided on the base 1 for mounting the ventilation assembly 7 .

[0031] A ventilation assembly 7 is installed inside the installation cavity 101 . In order to ensure ventilation around the product, the diameter of the installation cavity 101 is larger than the fixed mold 5 .

[0032] The ventilation assembly 7 includes a ventilation net 1 701, a ventilation net 2 702 and a blowing fan 703. The ventilation net 1 701 is arranged at the bottom of the installation cavity 101, the ventilation net 2 702 is arranged at the top of the installation cavity 101 and is located at the bottom of the fixed mold 5. The diameter of the ventilation net 2 702 is larger than the diameter of the fixed mold 5. The blowing fan 703 is arranged at the top of the ventilation net 1 701 and is located inside the installation cavity 101.

[0033] A plurality of cooling fins 8 are evenly arranged at the bottom of the second ventilation net 702 , and the cooling fins 8 are located inside the installation cavity 101 .

[0034] Ventilation net 1 701 and ventilation net 2 702 are mesh structures with multiple ventilation holes on the surface and are fixedly connected to the base 1 for installing a blowing fan 703 and a cooling plate 8 for ventilation. The fixed mold 5 is connected to the base 1 through ventilation net 2 702. The staff starts the blowing fan 703 and the cooling plate 8 to blow cold air to the fixed mold 5 on the top of ventilation net 2 702 to dissipate heat from the bottom of the product. The device is convenient for ventilation and cooling, and facilitates ventilation and heat dissipation of the product.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, a square wind collecting hood 9 is arranged on the top of the base 1. The wind collecting hood 9 is composed of two half-pieces of a rectangular shell and is fixed on the base 1 by screws. The wind collecting hood 9 covers the fixed mold 5. The diameter of the wind collecting hood 9 is larger than the diameter of the ventilation net 702. The diameter of the wind collecting hood 9 needs to be larger than the diameter of the ventilation net 702 so as to cover the fixed mold 5 and the ventilation net 702 inside at the same time.

[0036] The blowing fan 703 will blow the cold wind out of the ventilation net 702, and then the wind collecting cover 9 will collect the cold wind around the fixed mold 5 to cool the product in all directions. This device is convenient for collecting wind and dissipating heat for the product as a whole.

[0037] In summary, when the mold with a reverse top is used, the staff first starts the electric push rod 3 to lift it downward, and the electric push rod 3 drives the movable mold 4 at the bottom to move downward so that the bottom protrusion moves into the groove with the fixed mold 5 to form an injection cavity, and then the material is transported to the injection cavity through the feed port for processing. The staff starts the blowing fan 703 and the refrigeration plate 8 to blow cold air to the fixed mold 5 on the top of the ventilation net 2 702 to dissipate the heat from the bottom of the product. At the same time, the blowing fan 703 will blow the cold air out of the ventilation net 2 702, and then the wind gathering hood 9 will gather the cold air around the fixed mold 5 to cool the product in all directions. After the product processing is completed, the staff starts the electric push rod 3 to retract upward, and then drives the movable mold 4 to move upward. As the movable mold 4 moves upward, the bottom end of the push rod 601 pushes out the movable mold 4, thereby pushing the bottom product down for unloading. This is the working principle of the mold with a reverse top.
