Description

Technical Field

[0001] The utility model relates to the technical field of filter valve production, and particularly relates to a mold structure for a movable insert of a filter valve. Background Technique

[0002] A filter valve is a valve used to control the flow of fluid. It has a filtering function and can remove impurities or particles in the fluid. This kind of valve is widely used in industries, agriculture, medical treatment and daily life to ensure the cleanliness of the fluid and the safe operation of the system. The movable inserts of the filter valve usually refer to the movable parts inside the filter valve, and these parts play a key role in the filtering process. Molds are required in the production process of the movable inserts of the filter valve.

[0003] At present, during the production of existing movable inserts, it is necessary to cool the completed movable inserts to facilitate the molding of the movable inserts. Although the existing molds contain cooling systems, the cooling systems cool the entire mold, resulting in a poor cooling effect on the movable inserts. As a result, the internal temperature of the movable inserts is still relatively high after being manufactured, making it difficult for workers to directly take them out by hand. Moreover, due to their high temperature, the movable inserts are prone to deformation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mold structure for a movable insert of a filter valve to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mold structure for a movable insert of a filter valve includes a mold body. The upper mold of the mold body is fixed with a hollow model for the molding of the movable insert through bolts. The lower mold of the mold body is fixed with a module for the molding of the movable insert through bolts. The top surface of the fixing plate of the upper mold of the mold body is fixed with a cooling mechanism. The cooling mechanism includes a water tank fixed to the top surface of the fixing plate of the upper mold of the mold body. A circulation component is arranged above the water tank. The circulation component includes a cylindrical barrel. A piston is slidably connected inside the cylindrical barrel. The bottom end of the outer wall of the cylindrical barrel is fixedly penetrated with a water outlet pipe communicated with the inside of the model. The inner bottom surface of the cylindrical barrel is fixedly penetrated with a water inlet pipe communicated with the inside of the water tank. The water inlet pipe extends to the inner bottom of the water tank.

[0007] Furthermore: The top surface of the water tank is fixedly connected with a U-shaped frame fixedly penetrated with the cylindrical barrel. An electric push rod is fixedly penetrated through the top surface of the U-shaped frame. The top surface of the piston is fixedly connected with a push rod slidably penetrated through the top surface of the cylindrical barrel. A connecting plate is fixedly connected between the top end of the push rod and the output end of the electric push rod.

[0008] Furthermore, a one-way valve 1 is provided inside the water outlet pipe and the water inlet pipe, an air inlet pipe is fixed through the bottom end of the outer wall of the cylindrical tube, and a one-way valve 2 is provided inside the air inlet pipe.

[0009] Furthermore, solenoid valves are fixed on the outer walls of the air inlet pipe and the water inlet pipe, and the two solenoid valves are respectively communicated with the inside of the air inlet pipe and the water inlet pipe.

[0010] Furthermore, a connecting pipe is fixedly connected between the water tank and the interior of the model.

[0011] Furthermore, a plurality of heat conducting plates are fixedly passed through one side of the water tank at equal intervals, a support frame is fixedly connected to one side of the water tank, and two fans are embedded and fixedly mounted on the side of the support frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Through the circulation of coolant, the movable insert can be cooled down from the injection molding process to the time when it is taken out by the staff. Therefore, the deformation caused by excessive internal temperature of the movable insert during the removal process can be prevented, thus ensuring the qualified rate of the movable insert production.

[0014] 2. By closing the solenoid valve at the water inlet pipe and opening the solenoid valve at the air inlet pipe, the electric push rod can be activated to press the external gas into the mold, so that the pressure of the mold increases and the coolant inside is pressed into the water tank through the connecting pipe. This can prevent the coolant from cooling the plastic when the molten plastic is poured in, thereby avoiding the situation where the movable insert cannot be molded smoothly;

[0015] 3. By starting the two fans, the heat absorbed by the coolant can be blown away, thereby cooling the coolant and improving the coolant's heat absorption efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 5 In an embodiment of the utility model, a filter valve movable insert mold structure includes a mold body 1, the upper mold of the mold body 1 is fixed with a model 11 with a hollow interior for movable insert molding by bolts, the lower mold of the mold body 1 is fixed with a module 12 for movable insert molding by bolts, and a cooling mechanism 2 is fixed on the top surface of the fixed plate of the upper mold of the mold body 1. The cooling mechanism 2 includes a water tank 21 fixed to the top surface of the fixed plate of the upper mold of the mold body 1, and a circulation component 22 is arranged above the water tank 21. The circulation component 22 includes a cylindrical barrel 221, and a piston is slidably connected to the interior of the cylindrical barrel 221. The bottom end of the outer wall of the cylindrical barrel 221 is fixed with a water outlet pipe 222 that is connected to the interior of the model 11, and the inner bottom surface of the cylindrical barrel 221 is fixed with a water inlet pipe 223 that is connected to the interior of the water tank 21. The water inlet pipe 223 extends to the inner bottom of the water tank 21.

[0024] Specifically, first, coolant is poured into the water tank 21. When the upper and lower molds of the mold body 1 are pressed against each other, the molten plastic is poured into the space between the model 11 and the module 12 through the feeding mechanism, and then the molten plastic is cooled by the cooling system of the mold body 1. At the same time, the cooling liquid in the water tank 21 can be pressed into the model 11 by the piston moving up and down in the cylindrical barrel 221, which can accelerate the cooling and molding of the movable insert between the model 11 and the module 12. When the upper and lower molds in the mold body 1 are separated and returned to their original positions, the piston stops moving, and the cooling liquid can be stopped from being pressed into the model 11. Then the staff removes the movable insert from the model 11. Since the coolant cools the movable insert during the injection molding process until the staff removes it, it can prevent the movable insert from being deformed due to its internal temperature being too high when it is taken out, thereby ensuring the qualified rate of the movable insert production.

[0025] Example 1

[0026] like Figure 4 and Figure 5 As shown, in this embodiment, the top surface of the water tank 21 is fixedly connected to a shaped frame 211 that passes through and is fixed to the cylindrical tube 221, the top surface of the shaped frame 211 is fixedly passed through and is fixed with an electric push rod 228, the top surface of the piston is fixedly connected to a push rod that slides through and passes through the top surface of the cylindrical tube 221, a connecting plate 227 is fixedly connected between the top end of the push rod and the output end of the electric push rod 228, and a one-way valve is provided inside the water outlet pipe 222 and the water inlet pipe 223.

[0027] In this embodiment, the push rod 228 is activated to drive the push rod and the piston to move through the connecting plate 227. Since a one-way valve is provided inside the water inlet pipe 223 and the water outlet pipe 222, when the piston moves upward, the coolant in the water tank 21 can be pumped into the cylindrical barrel 221. When the piston moves downward, the coolant in the cylindrical barrel 221 can be hydraulically injected into the mold 11, so that the coolant circulates in the mold 11, thereby accelerating the cooling and molding of the movable insert between the model 11 and the module 12.

[0028] Example 2

[0029] like Figure 5 As shown, in this embodiment, an air intake pipe 225 is fixed through the bottom end of the outer wall of the cylindrical tube 221, and a one-way valve is provided inside the air intake pipe 225. Two solenoid valves 226 are fixed on the outer walls of the air intake pipe 225 and the water inlet pipe 223. The two solenoid valves 226 are respectively connected to the interior of the air intake pipe 225 and the water inlet pipe 223, and a connecting pipe 224 is fixedly connected between the water tank 21 and the interior of the model 11.

[0030] In this embodiment, when the molten plastic is poured between the mold 11 and the module 12, the solenoid valve 226 at the water inlet pipe 223 is closed and the solenoid valve 226 at the air inlet pipe 225 is opened. At this time, the activation of the electric push rod 228 can draw the external gas into the cylindrical tube 221 and press the gas in the cylindrical tube 221 into the mold 11, so that the pressure of the mold 11 increases and the coolant inside it is pressed into the water tank 21 through the connecting pipe 224. This can prevent the coolant from cooling the plastic when the molten plastic is poured, thereby avoiding the situation where the movable insert cannot be smoothly molded. When the molten plastic is stopped being poured, the solenoid valve 226 at the air inlet pipe 225 is closed, and the solenoid valve 226 at the water inlet pipe 223 is opened. At this time, the cooling liquid in the water tank 21 can be pressed into the mold 11 to accelerate the molding of the movable insert.

[0031] Example 3

[0032] like Figure 3As shown, in this embodiment, a plurality of heat conducting plates 212 are fixedly passed through one side of the water tank 21 at equal intervals. A support frame 213 is fixedly connected to one side of the water tank 21 , and two fans 214 are embedded and fixed on the side of the support frame 213 .

[0033] In this embodiment, since the temperature of the coolant will become higher after absorbing a large amount of heat, the coolant will reduce the absorption of heat. At this time, the coolant can transfer the heat to the multiple heat-conducting plates 212, and then the heat on the multiple heat-conducting plates 212 can be blown away by starting the two fans 214, thereby cooling the coolant and improving the heat absorption efficiency of the coolant.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
