Description

Technical Field

[0001] The utility model relates to the technical field of water replenishment for mold temperature controllers, and particularly relates to an integrated water replenishment system for mold temperature controllers. Background Art

[0002] A mold temperature controller, also known as a mold temperature control machine, is a mechanical device that includes heating and cooling functions and is used for industrial temperature control. It is widely used in various industries such as plastic molding, light guide plate die casting, rubber tires, rollers, chemical reaction kettles, bonding, and internal mixing.

[0003] Mold temperature controllers can be divided into water-type mold temperature controllers and oil-type mold temperature controllers. Water-type mold temperature controllers have fast heat transfer, are clean, and are convenient to use. They generally adopt the design principles of direct heating and direct cooling. During the working process of water-type mold temperature controllers, cooling water is required for cooling. However, if the inlet water pressure is too high, it will affect the service life of components such as solenoid valves in the unit. If the inlet water pressure of the mold temperature controller is too low, the water replenishment is insufficient or the water cannot be replenished, which will lead to problems such as dry burning of the mold temperature controller, burnout of heating tubes, and slow cooling speed. Therefore, a good water replenishment system for mold temperature controllers is the guarantee for the good operation of mold temperature controllers. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated water replenishment system for mold temperature controllers, which has the advantages of independent setting, automatic water replenishment, stable water replenishment pressure, and flexible use, aiming at the defects and deficiencies of the existing technology.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an integrated water replenishment system for mold temperature controllers, including:

[0006] A water tank, in which a water level sensor for sensing the water level of the water tank is arranged;

[0007] An inlet water pipeline, one end of which is connected to the water tank and the other end is connected to an external water source for replenishing water to the water tank; an inlet water solenoid valve is arranged on the inlet water pipeline;

[0008] An internal circulation pipeline, its first end is connected to the lower part of the water tank, and the second end is connected to the water tank; a circulation pump is arranged in the internal circulation pipeline, and the circulation pump is used to increase the liquid pressure in the internal circulation pipeline to pump the liquid from the first end to the second end;

[0009] A water replenishment pipeline, one end of which is connected to the internal circulation pipeline and is located behind the circulation pump, and the other end is connected to the water replenishment port of the mold temperature controller. A water replenishment solenoid valve and a pressure sensor are arranged on the water replenishment pipeline, and the pressure sensor is arranged behind the water replenishment solenoid valve;

[0010] The water inlet solenoid valve is electrically connected to the water level sensor to open the water inlet solenoid valve to replenish water to the water tank when the water tank is short of water, and to close the water inlet solenoid valve to stop replenishing water to the water tank when the water volume in the water tank is sufficient;

[0011] The pressure sensor is electrically connected to the water replenishing solenoid valve and the circulation pump to open the water replenishing solenoid valve and start the circulation pump to replenish water to the mold temperature controller through the water replenishing pipeline when the pressure sensor senses that the water replenishing pipeline is lower than the first set pressure; to close the water replenishing solenoid valve when the pressure sensor senses that the water replenishing pipeline reaches the second set pressure, and to close the circulation pump when the pressure sensor does not sense that the pressure of the water replenishing pipeline is lower than the first set pressure within the pressure setting time of the water replenishing pipeline.

[0012] The present utility model is further provided that the water level sensor includes: a low water level sensor and a high water level sensor.

[0013] The present utility model is further provided that the first end of the internal circulation pipeline is lower than the position of the low water level sensor.

[0014] The present utility model is further provided that it further includes a drainage pipeline connected to the bottom of the water tank, and a drainage valve is provided on the drainage pipeline.

[0015] The present utility model is further provided that a check valve is further provided at the front end of the pressure sensor on the water replenishing pipeline to prevent the water in the water replenishing pipeline from flowing back into the circulation loop.

[0016] The present utility model is further provided that a flow meter is further provided at the rear end of the water replenishing solenoid valve on the water replenishing pipeline.

[0017] The present utility model is further provided that a pressure stabilizing tank is further provided at the rear end of the pressure sensor on the water replenishing pipeline.

[0020] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0021] 1. In the present utility model, the water inlet solenoid valve is electrically connected to the water level sensor. When the water level sensor senses that the inside of the water tank is short of water, the water inlet solenoid valve will be opened, and water will be replenished to the water tank through the water inlet pipeline to ensure sufficient water volume inside the water tank; at the same time, when the water level sensor senses that the water volume in the water tank is sufficient, the water inlet solenoid valve will be closed to stop replenishing water to the water tank, avoiding water overflow from the water tank due to excessive water replenishment. Thus, automatic water replenishment of the water tank is achieved.

[0022] 2. In the present utility model, the pressure sensor is electrically connected to the water replenishing solenoid valve and the circulation pump. The pressure sensor is used to detect the pressure inside the water replenishing pipeline. When the pressure sensor senses that the pressure inside the water replenishing pipeline is lower than the first set pressure, it is considered that the molding press needs to be replenished with water. Then the water replenishing solenoid valve will be opened and the circulation pump will be started. The circulation pump will increase the pressure inside the internal circulation pipeline and pump the water into the water replenishing pipeline, increasing the pressure of the liquid inside the water replenishing pipeline to replenish water to the molding press. When the pressure sensor senses that the water replenishing pipeline reaches the second set pressure, that is, the water replenishing pressure of the mold temperature controller is sufficient, the water replenishing solenoid valve will be closed first to stop the pressure inside the water replenishing pipeline from continuing to increase, avoiding damage to the mold temperature controller caused by excessive pressure inside the water replenishing pipeline. After the pressure sensor senses that the pressure inside the water replenishing pipeline does not drop below the first set pressure within the set time, the circulation pump will be closed. If the pressure sensor senses that the pressure inside the water replenishing pipeline is lower than the first set pressure within the set time, only the water replenishing solenoid valve needs to be opened to increase the pressure of the water replenishing pipeline and replenish water to the mold temperature controller, which can avoid frequent startup of the circulation pump and damage to the circulation. Thus, the automatic water replenishment of the mold temperature controller by the water replenishment system is realized, and a good water replenishment effect is achieved.

[0023] 3. In the present utility model, the first set pressure, the second set pressure, and the set time can all be adjusted according to different usage environments, but the value of the first set pressure is always not greater than the value of the second set pressure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0028] This specific embodiment is only an explanation of the present utility model and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0029] This embodiment relates to an integrated water replenishment system for a mold temperature controller, as Figure 1 shown, including: a water tank 100, a water inlet pipeline 200, an internal circulation pipeline 300, and a water replenishment pipeline 400.

[0030] In this embodiment, the direction of water flow is defined as the back.

[0031] Among them, a water level sensor for sensing the water level of the water tank 100 is provided inside the water tank 100; one end of the water inlet pipeline 200 is connected to the water tank 100, and the other end is connected to an external water source, for replenishing water to the water tank 100 through the water inlet pipeline 200 to ensure sufficient water volume in the water tank 100. An inlet solenoid valve 210 is provided on the water inlet pipeline 200 for controlling the on / off of the water inlet pipeline 200, that is, the start / stop of water replenishment to the water tank 100; the first end 320 of the internal circulation pipeline 300 is connected to the lower part of the water tank 100, and the second end 330 is also connected to the water tank 100. A circulation pump 310 is provided in the internal circulation pipeline 300. The circulation pump 310 is used for pumping the liquid in the internal circulation pipeline 300, increasing the liquid pressure in the internal circulation pipeline 300, and pumping the liquid from the first end 320 to the second end 330; one end of the water replenishment pipeline 400 is connected to the internal circulation pipeline 300 and is located at the rear of the circulation pump 310, and the other end is connected to the water replenishment port of the mold temperature controller, so that the liquid in the internal circulation pipeline 300 will also be pumped into the water replenishment pipeline 400 under the action of the circulation pump 310 to replenish water to the module machine; a water replenishment solenoid valve 410 and a pressure sensor 420 are provided on the water replenishment pipeline 400. The pressure sensor 420 is provided at the rear of the water replenishment solenoid valve 410; the pressure sensor 420 is used for detecting the pressure in the water replenishment pipeline 400, and the water replenishment solenoid valve 410 is used for controlling the conduction or non-conduction between the internal circulation pipeline 300 and the water replenishment pipeline 400.

[0032] The inlet solenoid valve 210 is electrically connected to the water level sensor. When the water level sensor senses that the water tank 100 is short of water, it will open the inlet solenoid valve 210 to replenish water to the water tank 100 through the water inlet pipeline 200 to ensure sufficient water volume inside the water tank 100; at the same time, when the water level sensor senses that the water volume in the water tank 100 is sufficient, it will close the inlet solenoid valve 210 to stop replenishing water to the water tank 100, avoiding water overflow from the water tank 100 due to excessive water replenishment. Thus, automatic water replenishment of the water tank 100 is achieved.

[0033] The pressure sensor 420 is electrically connected to the water replenishing solenoid valve 410 and the circulation pump 310. The pressure sensor 420 is used to detect the pressure inside the water replenishing pipeline 400. When the pressure sensor senses that the pressure in the water replenishing pipeline 400 is lower than the first set pressure, it is considered that the molding press needs water replenishment. The water replenishing solenoid valve 410 will be opened and the circulation pump 310 will be started. The circulation pump 310 will increase the pressure in the internal circulation pipeline 300 and pump the water to the water replenishing pipeline 400, increasing the pressure of the liquid inside the water replenishing pipeline 400 to replenish water for the molding press. When the pressure sensor 420 senses that the water replenishing pipeline 400 reaches the second set pressure, that is, the water replenishing pressure of the mold temperature controller is sufficient, the water replenishing solenoid valve 410 will be closed first to stop the pressure in the water replenishing pipeline 400 from continuing to increase, avoiding damage to the mold temperature controller due to excessive pressure in the water replenishing pipeline 400. After the pressure sensor 420 senses that the pressure in the water replenishing pipeline 400 does not drop below the first set pressure within the set time, the circulation pump 310 will be closed. If the pressure sensor 420 senses that the pressure in the water replenishing pipeline 400 is lower than the first set pressure within the set time, only the water replenishing solenoid valve 410 needs to be opened to increase the pressure of the water replenishing pipeline 400 to replenish water for the mold temperature controller, which can avoid frequent startup of the circulation pump 310 and damage to the circulation. Thus, the water replenishing system realizes automatic water replenishment for the mold temperature controller and achieves a good water replenishing effect.

[0034] When the circulation pump 310 is running and the water replenishing solenoid valve 410 is closed, the circulation pump 310 will pump the liquid in the internal circulation pipeline 300 from the first end 320 to the second end 330 to realize the internal circulation module and ensure the normal operation of the circulation pump 310. The first set pressure, the second set pressure, and the set time can all be adjusted according to different usage environments, but the value of the first set pressure is always not greater than the value of the second set pressure. In other embodiments, the set time can also be 0. When the pressure sensor 420 senses that the water replenishing pipeline 400 reaches the second set pressure, the circulation pump 310 will be immediately closed.

[0035] In this embodiment, the water level sensor includes a low water level sensor 110 and a high water level sensor 120, which are respectively arranged at the upper and lower parts of the water tank 100 to ensure a good water level sensing effect. As a preferred solution, the first end 320 of the internal circulation pipeline 300 is lower than the position of the low water level sensor 110 to prevent the circulation pump 310 from idling when the water level in the water tank 100 has not reached the low water level, unable to achieve the water replenishing effect and easily causing damage to the circulation pump 310.

[0036] In this embodiment, the water replenishing system further includes a drainage pipeline 500 connected to the bottom of the water tank 100 for draining the water tank 100. A drainage valve 510 is arranged on the drainage pipeline 500 to control the on-off of the drainage pipeline 500.

[0037] As a preferred solution, a check valve 430 is further provided on the makeup water pipeline 400. The check valve 430 is arranged at the front end of the pressure sensor 420, which can prevent the water in the makeup water pipeline 400 from flowing back into the circulation loop and avoid interference of the check valve 430 on the pressure sensor 420. In this embodiment, a flow meter 440 is further provided on the makeup water pipeline 400, behind the makeup water solenoid valve 410, which can detect the flow rate of the makeup water pipeline 400, count the makeup water consumption of the mold temperature controller, and at the same time can issue an alarm when the flow meter 440 detects that the makeup water consumption of the mold temperature controller is excessive, so as to facilitate the staff to check the water leakage situation of the mold temperature controller and reduce potential safety hazards.

[0038] In this embodiment, a pressure stabilizing tank 450 is further provided on the makeup water pipeline 400, behind the pressure sensor 420. The pressure stabilizing tank 450 can stabilize the water pressure and prevent the pressure of the makeup water for the mold temperature controller from being unstable. At the same time, the pressure stabilizing tank 450 has a certain capacity and can store a certain amount of water to ensure the water volume of the makeup water pipeline 400 and avoid frequent changes in the pressure in the makeup water pipeline 400 when the makeup water solenoid valve 410 is opened, resulting in frequent startup of the circulation pump 310 and affecting the service life of the circulation pump 310.

[0039] In this embodiment, a water inlet valve 220 is further provided on the water inlet pipeline 200 to manually close the water inlet pipeline 200; a makeup water valve 460 is further provided near the makeup water pipeline 400 to manually close the makeup water pipeline 400. As a preferred solution, an inner circulation valve 340 is further provided on the inner circulation pipeline, behind the connection port of the makeup water pipeline 400, which can adjust the flow rate of the inner circulation pipeline 300 to ensure the pressure output of the circulation pump 310 for the makeup water pipeline 400.

[0040] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
