Description

Technical Field

[0001] The utility model belongs to the technical field of casting molds, and particularly relates to a casting mold for a fuel injection pump flange. Background Art

[0002] An oil pump flange is a mechanical component used to connect and seal an oil pump with a pipeline or equipment. It is used to connect the oil pump with the pipeline or other equipment to ensure the smooth flow of fluid between them. At the same time, it prevents oil leakage at the connection, ensuring the sealing and safety of the system. They are usually made of metal materials, can withstand a certain pressure and temperature, and are suitable for different types of oil pumps and industrial environments;

[0003] During the production process of the flange, the heated material is pressed into a preliminary flange shape by a mold on a forging machine. In this process, if the mold does not have a cooling structure, due to the low cooling efficiency, the production cycle is prolonged, resulting in an increase in the manufacturing cost of a single flange and a reduction in production efficiency. Due to the low cooling efficiency, the long-term high-temperature effect may accelerate the aging and wear of the mold material and reduce the service life of the mold.

[0004] Therefore, we hope to design a casting mold for a fuel injection pump flange to solve this problem. Summary of the Utility Model

An installation frame 53 is fixedly connected to the lower side of the lower die 2. A water pump 54 is fixedly installed on the upper side of the installation frame 53. The output end of the water pump 54 is fixedly connected to the inlet water channel 52 through a pipe. The input end of the water pump 54 is fixedly connected to a heat dissipation bin 55 through a pipe. The right end of the heat dissipation bin 55 is connected to a flow distribution box 56 through a pipe. The upper side of the flow distribution box 56 is fixedly connected to an outlet water channel 57 through a pipe. By setting the circulating cooling component 5, the material in the mold cavity is cooled in a cycle.

[0025] A plurality of heat dissipation water channels are opened inside the heat dissipation bin 55. The heat dissipation water channels inside the heat dissipation bin 55 are in a horizontal S shape. The S-shaped heat dissipation water channels are used to extend the flow path of the coolant. The material of the heat dissipation bin 55 is aluminum metal. The heat dissipation bin 55 made of aluminum metal is used to improve the heat conductivity of the equipment.

[0026] A square through hole is opened on the left side of the flow distribution box 56. The square through hole is used to pass the coolant. The flow distribution box 56 is used to assist the coolant to enter the multiple heat dissipation water channels of the heat dissipation bin 55.

[0027] The heat dissipation component 6 includes a speed reducer 61 which is fixedly connected to the upper side of the bottom plate 1. A transmission component 62 is arranged on the output shaft of the speed reducer 61. A support column 63 is arranged on the transmission component 62.

[0028] The transmission component 62 includes a threaded rod 621 which is connected to the output shaft of the speed reducer 61 through a bushing. A sleeve 622 is sleeved on the outside of the threaded rod 621 through a thread. A slider 623 is fixedly connected to the outside of the sleeve 622.

[0030] Please refer to Figures 1 - 3, as the first embodiment of the present utility model: To solve the problem that due to low cooling efficiency and extended production cycle, the manufacturing cost of a single flange increases, reducing production efficiency. After pouring is completed, start the water pump 54. The water pump 54 drives the coolant in the internal cooling water channel 51 of the lower mold 2 to flow. The coolant first flows from the water pump 54 through the water inlet channel 52 into the interior of the cooling water channel 51, and then the coolant flows out through the water outlet channel 57. During the flow of the coolant, the mold heats the coolant, and then the coolant takes away the heat and flows into the interior of the flow distribution box 56. Then, the water pump 54 pumps the coolant through the pipeline into multiple heat dissipation water channels inside the heat dissipation chamber 55. The S-shaped heat dissipation water channels extend the flow path of the coolant in the heat dissipation chamber 55 and extend the duration of heat transfer of the coolant in the heat dissipation chamber 55. After being cooled, the coolant is pumped into the water inlet channel 52 by the water pump 54 again, and then the above steps are cycled to complete the circulating cooling of the mold by the coolant.

[0031] Please refer to Figures 2 - 4 , as the second embodiment of the present utility model: Based on the description in the above embodiment, further, after the coolant absorbs a large amount of heat, the refrigeration effect of the coolant will be reduced. At this time, it is necessary to dissipate the heat of the coolant to improve the heat dissipation effect. First, start the reduction gear 61. The output shaft of the reduction gear 61 drives the threaded rod 621 to rotate. The threaded rod 621 and the sleeve 622 perform a threaded movement, causing the sleeve 622 to displace. During the displacement of the sleeve 622, the support column 63 fixedly connected to it is driven to move. The support column 63 drives the mounting plate 64 at its upper end to move. Finally, the mounting plate 64 drives the semiconductor refrigeration block 65 to move to absorb the heat transferred between the heat dissipation chamber 55 and the coolant, so as to improve the heat dissipation effect of the equipment.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
