Description

Technical Field

[0001] This utility model relates to mold temperature controllers, specifically explosion-proof mold temperature controllers, and belongs to the field of mold temperature controller technology. Background Technology

[0002] Mold temperature controllers (mold temperature control units) are indispensable key equipment in industrial production, especially in processes such as plastic molding, die casting, and rubber vulcanization. Their main function is to maintain the mold within the stable temperature range required by the process by precisely controlling the temperature of the heating or cooling medium, thereby ensuring product quality, improving production efficiency, and reducing defects. A typical mold temperature controller consists of a heating system, a circulating pump, a temperature control system, and piping. Its working medium (such as water or heat transfer oil) circulates in a closed system to achieve heat transfer and exchange.

[0003] However, existing mold temperature controllers have certain safety hazards and performance defects in practical applications, especially during long-term operation. Their water source or circulating medium often contains impurities such as solid particles, scale, and rust. Although some equipment is equipped with filtration devices, these filters are usually fixed in structure, integrated inside the system, or cumbersome to maintain. Impurities gradually accumulate on the heater surface, pipe inner walls, and valves during long-term circulation, forming scale. This not only significantly reduces the system's heating efficiency and increases energy consumption, but more seriously, when scale accumulates in large quantities in critical parts of the heater (such as electric heating elements), it can cause poor local heat dissipation, leading to abnormally high heater wall temperatures and generating enormous thermal stress. Prolonged overheating operation can easily cause heater rupture, medium leakage, and even serious safety accidents such as short circuits and fires—a "pipe burst" risk that threatens the safety of personnel and equipment.

[0004] Therefore, there is an urgent need for a mold temperature controller solution that can effectively intercept impurities at the source, is easy to maintain and clean, thereby fundamentally reducing the risk of heaters overheating and bursting due to scaling, and improving the safety and reliability of equipment operation. Summary of the Invention

[0005] The purpose of this invention is to provide an explosion-proof mold temperature controller to solve the above problems. With the help of a filter screen, the water is initially filtered, and the filtered water is then introduced into the filter for further filtration. This also prevents the heater inside the mold temperature controller from accumulating a large amount of dirt, thus preventing explosion. The filter screen can be pulled out by rotating the sealing cover, which is convenient for regular cleaning and maintenance. The operation is also convenient.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5As shown, the explosion-proof mold temperature controller includes a mold temperature controller body 1, a filter 3 installed inside the mold temperature controller body 1, a filter mechanism 2 installed inside the mold temperature controller body 1, and a housing 204. The housing 204 is installed inside the mold temperature controller body 1, one end of the housing 204 extends to the outside of the mold temperature controller body 1, and a sealing cover 201 is threadedly connected to one end of the housing 204. A filter screen 209 is provided inside the housing 204, and an installation plate 207 is installed at one end of the filter screen 209. One side of the installation plate 207 is rotatably connected to the sealing cover 201 through a connecting shaft 208.

[0025] As a technical optimization of this utility model, the filter screen 209 has a cylindrical structure. One end of the filter screen 209 is detachably connected to a bottom cover 212, which facilitates the installation of the filter screen 209 inside the outer casing 204. Furthermore, the installation of the bottom cover 212 facilitates the sealing of one end of the filter screen 209, enabling water to be filtered through the filter screen 209 and then discharged.

[0026] As a technical optimization of this utility model, the bottom cover 212 has a disc-shaped structure. The bottom cover 212 is threadedly connected to one end of the filter screen 209. Two grooves 213 are provided on the outer side of the bottom cover 212. By opening the grooves 213, the rotation control of the bottom cover 212 can be realized, which facilitates the disassembly and assembly of the bottom cover 212 and the cleaning of the filter screen 209.

[0027] As a technical optimization of this utility model, the length of the filter screen 209 is less than the length of the outer shell 204, and there is a certain gap between the outer surface of the filter screen 209 and the inner wall of the outer shell 204, which facilitates the installation of the filter screen 209 inside the outer shell 204 and allows the filtered water to be discharged to the surrounding area of ​​the filter screen 209, thereby increasing the usable area of ​​the filter screen 209.

[0028] As a technical optimization of this utility model, an installation block 210 is installed on the outside of the filter screen 209. The installation block 210 is provided with a water inlet 211. The outside of the installation block 210 is slidably connected to the inner wall of the outer shell 204. By installing the installation block 210, after the filter screen 209 and the outer shell 204 are inserted, external water can be introduced into the filter screen 209 through the water inlet 211 to achieve the filtration of impurities in the water.

[0029] As a technical optimization of this utility model, the mounting block 210 has a rectangular structure. The outer side of the mounting block 210 is slidably connected to the inner wall of the outer shell 204. The installation of the mounting block 210 plays a guiding role and prevents the filter screen 209 from rotating inside the outer shell 204, thus preventing the water inlet 211 from shifting.

[0030] As a technical optimization of this utility model, an inlet pipe 205 and a drain pipe 206 are installed at the center of the outer side of the outer shell 204. The end of the inlet pipe 205 is located outside the inlet 211, and one end of the drain pipe 206 is connected to the filter 3. Through the installation of the inlet pipe 205, external water is introduced into the filter screen 209, which is conducive to filtering impurities from the water. The filtered water is then introduced into the filter 3 for deep purification through the drain pipe 206.

[0031] As a technical optimization of this utility model, a sealing ring 203 is installed at one end of the outer shell 204, the sealing cover 201 abuts against the sealing ring 203, and a handle 202 is installed on the outside of the sealing cover 201. The installation of the sealing ring 203 facilitates good sealing between the sealing cover 201 and the outer shell 204, and the handle 202 facilitates the driving control of the sealing cover 201.

[0032] As a technical optimization of this utility model, a protective mechanism 4 is installed on the outer shell 204. The protective mechanism 4 includes a baffle 401. The baffle 401 is slidably connected to the inside of the side wall of the outer shell 204 via a return spring 403. The baffle 401 is located between the water inlet pipe 205 and the water inlet 211. One end of the baffle 401 is provided with a through hole 402, which is located at the top of the water inlet 211. The end of the baffle 401 extends to the outside of the outer shell 204 and abuts against the sealing cover 201. The installation of the sealing cover 201 facilitates the contact between the baffle 401 and the return spring. When the spring 403 retracts, the through hole 402 on the baffle 401 is located at the top of the inlet 211, allowing water inside the inlet pipe 205 to be introduced into the filter screen 209 through the through hole 402 and the inlet 211. When the sealing cover 201 is opened, the baffle 401 slides out to a certain position under the force of the return spring 403, causing the through hole 402 on the baffle 401 to be offset from the inlet 211 by a certain position, thus blocking the inlet 211. At this time, water cannot enter the inlet pipe 205, making it easy to remove and maintain the filter screen 209 inside the outer casing 204.

[0033] As a technical optimization of this utility model, the baffle 401 has a rectangular structure, and the diameter of the through hole 402 is equal to that of the water inlet 211, which is conducive to the baffle 401 sealing the water inlet 211 well. At the same time, when the water inlet 211 and the through hole 402 are aligned, they play a good guiding role.

[0034] In use, the mold temperature controller body 1 is first installed stably (working principle reference: patent number 202320836805.4 Energy-saving and environmentally friendly high-temperature water mold temperature controller). The outer shell 204 is detachably installed to the inner side of the mold temperature controller body 1. Then, one end of the outer shell 204 extends to the outer side of the mold temperature controller body 1. The water inlet pipe 205 is then connected to the external pipe to supply water. The drain pipe 206 is then installed to the filter 3. Before the mold temperature controller body 1 starts working, the handle 202 is held, and the filter screen 209 is inserted into the outer shell 204. The sealing cover 201 is then rotated to seal the filter screen 209, ensuring it is stably installed inside the outer shell 204. After the sealing cover 201 is tightly sealed, the baffle 401 is retracted, allowing the water inlet 21 to be closed. 1. Water from the external pipe is delivered to the filter screen 209 through the inlet pipe 205, through hole 402, and inlet 211 to achieve preliminary filtration of impurities. The filtered water is then introduced into the filter 3 for deep filtration, ensuring that the heater inside the mold temperature controller body 1 does not accumulate a large amount of dirt and thus does not burst. During maintenance, by rotating the sealing cover 201, when the sealing cover 201 is removed and pulled out to a certain position, the baffle 401 slides out to a certain position under the resistance of the return spring 403, thus sealing the inlet 211. At this time, it is convenient to pull out the filter screen 209 for regular cleaning and maintenance.
