Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a plunger pump valve plate mold. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump valve plate is a component of the plunger pump. During the production of the valve plate, the high-temperature fluid needs to be cooled and formed. In the prior art, the Chinese utility model patent with the public document number: CN216373243U discloses a cooling system for injection molds. This utility model provides a pusher in the cooling box and connects it to the movable mold. When the movable mold moves to close the mold, the pusher causes the coolant in the cooling box to rise and fall and contact the fixed mold in the cooling box to cool it. This avoids the need for additional drive equipment and reduces production and use costs while ensuring stable cooling.

[0003] However, when the mold and the cooling water are in contact with each other, the upper layer of water is close to the heat source and has a higher temperature, while the lower layer of water is far from the heat source and has a lower temperature. This results in a large temperature difference between the upper and lower layers of the water, and the water temperature is uneven, resulting in a poor cooling effect on the moving mold above. Therefore, improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0020] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

The solution wraps the metal keel. After cooling, the strength of the plastic part is improved. In this way, metal parts can be mixed with plastic parts, which facilitates the diversity of materials, saves costs, reduces processing time, improves product precision, etc. Using mold production can save materials to achieve mass production.

[0022] The two sides of the B template 5 are fixedly connected with a ventilation component 11, which includes an annular exhaust pipe 1101, a lower air inlet pipe 1103, an anti-backflow box 1104, a dispersion pipe 1107, an exhaust box 1108 and a mist catcher 1112. The annular exhaust pipe 1101 is fixedly connected in the cooling chamber 12, the lower end of the lower air inlet pipe 1103 is fixedly connected to the annular exhaust pipe 1101, the upper end of the lower air inlet pipe 1103 passes through the B template 5 and is fixedly connected to the anti-backflow box 1104, the ventilation component 11 also includes a one-way air valve 1105 and an upper air inlet pipe 1106, and the upper air inlet pipe 1107 is fixedly connected to the cooling chamber 12. The air pipe 1106 is fixedly connected to the upper position of the anti-backflow box 1104, and the one-way air valve 1105 is fixedly connected to the upper air inlet pipe 1106. The ventilation component 11 also includes an exhaust port 1102, and the exhaust port 1102 is opened on the annular exhaust pipe 1101. The upper air inlet pipe 1106 is provided with a one-way air valve 1105 to avoid gas diversion. The upper air inlet pipe 1106 and the lower air inlet pipe 1103 are interconnected through the anti-backflow box 1104. The anti-backflow box 1104 is a transparent plastic part. When the liquid flows back, the liquid enters the anti-backflow box 1104, which is easy to be discovered by the user.

[0023] The dispersion pipe 1107 is fixedly connected to the side position of the B template 5, the exhaust box 1108 is fixedly connected to the side position of the dispersion pipe 1107, the mist catcher 1112 is fixedly connected to the exhaust box 1108, and the ventilation component 11 also includes a collection bin 1109, a drain pipe 1110 and a liquid level meter 1111. The collection bin 1109 is fixedly connected to the bottom position of the exhaust box 1108, the drain pipe 1110 is fixedly connected to the collection bin 1109, and the liquid level meter 1111 is fixedly connected to the exhaust box 110 8, the ventilation component 11 also includes a vent 1113, and the vent 1113 is fixedly connected to the upper position of the exhaust box 1108. The exhaust box 1108 introduces cooling water and gas into the box through the dispersion pipe 1107, and reduces the flow rate of the liquid by diverting the liquid. After the gas enters the exhaust box 1108, the gas and liquid are easily separated from each other. After the gas passes through the mist collector 1112 upward, it is discharged from the vent 1113, which facilitates gas-liquid separation and reduces the pressure of pipeline transportation.

[0024] It should be noted that the present invention is a plunger pump distribution plate mold, which allows cooling water to enter the cooling chamber 12 from the water inlet 13. A molding chamber is provided above the B template 5. During the mold closing process, a metal keel is added to the molding chamber. When the molten solution is injected, the solution wraps the metal keel, thereby improving the strength of the plastic part. When the mold is disassembled, the ejector panel 8, the ejector plate 6 and the ejector rod 10 move upward to eject the plastic part out of the molding chamber. During the mold closing process, the cooling water flows in the cooling chamber 12 to cool the workpiece in the molding chamber at the upper position. At the same time, the external cold air enters from the upper air inlet pipe 1106, then enters the anti-backflow box 1104 and the lower air inlet pipe 1103, and finally enters the annular exhaust pipe 1101. The cold air is discharged through the exhaust port 1102, causing the gas to float upward on the liquid. A large number of tiny liquid bubbles are generated in the cooling water, which shakes the liquid, so that the temperature difference between the upper and lower layers of the liquid is small. The water temperature is uniform, thereby improving the cooling effect on the workpiece in the molding chamber, and then the gas mixed liquid is discharged from the drain 14. The drain 14 is interconnected with the dispersion pipe 1107. The dispersion pipe 1107 diverts the liquid. Since the liquid contains some gas, the pressure of the mixture is enhanced, which easily increases the pressure of the pipeline transportation. After the dispersion pipe 1107 diverts the liquid, the liquid flow rate is reduced, and the dispersed liquid then enters the exhaust box 1108. The gas and cooling water are separated from each other, so that the gas flows upward and separates from the liquid. After the gas passes through the mist collector 1112 to remove the water mist, it is discharged upward through the vent 1113. The liquid is concentrated toward the collecting bin 1109 and then discharged through the drain pipe 1110, thereby reducing the pipeline transportation pressure. A liquid level gauge 1111 is provided on the side of the exhaust box 1108 to display the liquid level in the exhaust box 1108, alerting the user to prevent the liquid from flowing out of the vent 1113.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
