Description

Technical Field

[0001] The utility model relates to the field of mold temperature control equipment, in particular to an energy-saving mold temperature control machine for plastic products. Background Art

[0002] The plastic energy-saving mold temperature control machine is a temperature control device designed specifically for the plastic processing industry, aiming to improve energy efficiency and reduce energy consumption. It is mainly used for heating and controlling the temperature in injection-molded plastic molds or extrusion molding processes. Through precise temperature management, it ensures that the melting, fluidity, and curing processes of plastic raw materials reach the optimal state to form high-quality products.

[0003] In the existing energy-saving mold temperature control machine for plastic products, when the temperature of the fuel tank is too high, the water in the water tank can quickly enter the heat preservation box through the water pipe under the suction of the water pump, and cool the heat conduction fins in contact with the fuel tank. Through heat exchange, the temperature of the fuel tank and the oil temperature inside the tank can be quickly reduced. This cooling method can effectively reduce the large amount of electrical energy consumption brought by cooling through the cooling pipe. At the same time, the normal temperature in the water tank will not cause a sharp change in the oil temperature in the fuel tank, thus achieving an accurate fine-tuning effect.

[0004] However, in the above operation, the contact area between the water pipe and the heat conduction fin is limited. Driven by the water pump, the water flow has a short contact time and a small contact area, resulting in low heat exchange efficiency and failing to fully utilize the cold energy of the water flow, affecting the rapid cooling effect.

[0005] Therefore, it is necessary to provide a new energy-saving mold temperature control machine for plastic products to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides an energy-saving mold temperature control machine for plastic products.

[0007] The energy-saving mold temperature control machine for plastic products provided by the utility model includes a mold temperature housing. Inside the mold temperature housing, there is a fuel tank and a water tank. One side of the water tank adjacent to the fuel tank is detachably connected with a water pipe through a thread. The cross-section of the water pipe is semicircular and rectangular. The water pipe continuously bends along the outer side of the fuel tank and extends back into the inner cavity of the water tank. The outer side wall of the water pipe is fixedly connected with heat conduction fins, and the heat conduction fins extend into the inner cavity of the water pipe. The heat conduction fins located in the inner cavity of the water pipe are inclined in a gradually shrinking manner towards the water tank.

[0008] Further, a heat preservation box is fixedly connected to the outside of the fuel tank inside the mold temperature housing.

[0009] Further, a constant temperature cavity is formed between the heat preservation box and the fuel tank.

[0010] Further, the water pipe and the heat conduction fins are placed in the constant temperature cavity of the heat preservation box, and the water pipe and the heat conduction fins are not in contact with the heat preservation box.

[0011] Further, two semi-circular rectangular grooves are formed on one side of the heat preservation box adjacent to the water tank. The water delivery pipe is placed in the two semi-circular rectangular grooves, and a sealed setting is adopted between the semi-circular rectangular grooves and the water delivery pipe.

[0012] Further, sliding members are respectively arranged at the four corners of the bottom of the mold temperature housing. The sliding members are universal wheels, and the tops of the universal wheels are fixedly connected to the mold temperature housing.

[0013] Compared with the related art, the energy-saving mold temperature machine for plastic products provided by the present utility model has the following beneficial effects:

[0014] For the energy-saving mold temperature machine for plastic products, the cross-section of the water delivery pipe is semi-circular rectangular. The semi-circular rectangular cross-section design is beneficial to fluid flow, reduces water resistance, and improves transmission efficiency. The water delivery pipe is continuously bent along the outer side of the fuel tank and extends back to the inner cavity of the water tank, which not only saves space but also ensures the smoothness of the water flow path, effectively transfers heat, and reduces dead zones.

[0015] A heat conduction fin is fixedly connected to the outer side wall of the water delivery pipe. The heat conduction fin extends into the inner cavity of the water delivery pipe. The heat conduction fin located at the position in the inner cavity of the water delivery pipe is inclined in a gradually reducing and then increasing manner towards the water tank. The heat conduction fin closely adheres to the outer wall of the water delivery pipe and extends into the inner cavity, increasing the contact area between the water flow in the water delivery pipe and the heat conduction fin, improving the heat exchange efficiency between cold and heat. The heat conduction fin at the position in the water pipe cavity is designed to be gradually reducing and then increasing, with a small front end and a large rear end, causing a certain blockage when the water flow passes through, prolonging the water flow path, and increasing the cooling time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] In the specific implementation process, as shown in Figures 1 to 4 , the energy-saving mold temperature controller for plastic products provided by the present utility model includes a mold temperature housing 1. Inside the mold temperature housing 1, an oil tank 2 and a water tank 3 are arranged. On one side of the water tank 3 adjacent to the oil tank 2, a water delivery pipe 4 is detachably connected by threads. The water delivery pipe 4 is connected by threads to ensure tightness and facilitate disassembly and installation. The cross-section of the water delivery pipe 4 is semicircular rectangular. The semicircular rectangular cross-section design is beneficial to fluid flow, reduces water resistance, and improves transmission efficiency. The water delivery pipe 4 continuously bends along the outside of the oil tank 2 and extends back into the inner cavity of the water tank 3, which not only saves space but also ensures the smoothness of the water flow path, effectively transfers heat, and avoids dead zones. A heat conduction fin 5 is fixedly connected to the outer wall of the water delivery pipe 4, and the heat conduction fin 5 extends into the inner cavity of the water delivery pipe 4. The position of the heat conduction fin 5 in the inner cavity of the water delivery pipe 4 is inclined in a gradually shrinking manner towards the water tank 3;

[0024] The heat conduction fin 5 closely adheres to the outer wall of the water delivery pipe 4 and extends into the inner cavity. This design increases the contact area between the water flow in the water delivery pipe 4 and the heat conduction fin 5, improving the heat exchange efficiency between hot and cold. The heat conduction fin 5 at the position inside the water pipe cavity is designed to be gradually shrinking, with a small front end and a large rear end. This shape is similar to a trapezoid, causing a certain blockage when the water flow passes through, extending the water flow path, and increasing the cooling time.

[0025] Inside the mold temperature housing 1, a heat preservation box 6 is fixedly connected to the outside of the oil tank 2. A constant temperature cavity 7 is formed between the heat preservation box 6 and the oil tank 2. The water delivery pipe 4 and the heat conduction fin 5 are placed in the constant temperature cavity 7 of the heat preservation box 6, and the water delivery pipe 4 and the heat conduction fin 5 are arranged without contact with the heat preservation box 6. On one side of the heat preservation box 6 adjacent to the water tank 3, two semicircular rectangular grooves 8 are opened. The water delivery pipe 4 is placed in the two semicircular rectangular grooves 8, and a sealed setting is formed between the semicircular rectangular grooves 8 and the water delivery pipe 4;

[0026] The heat preservation box 6 closely adheres to the outside of the oil tank 2. The constant temperature cavity formed between the two not only isolates external heat loss but also provides a buffer zone for heat transfer. The water delivery pipe 4 is arranged in the constant temperature cavity of the heat preservation box 6. This design utilizes the cavity environment, not only protecting the water pipe but also promoting heat exchange for water temperature control and reducing heat consumption;

[0027] The heat-conducting sheet 5 is not in direct contact with the water delivery pipe 4 and the insulation box 6, avoiding heat energy loss, ensuring efficient heat transfer, and protecting the box body from heat damage at the same time;

[0028] The two semi-circular rectangular grooves 8 accurately place the water delivery pipe 4. This not only fixes the water delivery pipe 4 but also ensures the sealing of the flow channel, improving the stability and efficiency of the pipeline. The precise configuration of the seal between the semi-circular rectangular groove 8 and the water delivery pipe 4 ensures that water flows through without leakage, improving the reliability and energy efficiency of the overall system and reducing energy loss.

[0029] Sliding members are respectively arranged at the four corners of the bottom of the mold temperature housing 1. The sliding members are universal wheels 9. The top of the universal wheel 9 is fixedly connected to the mold temperature housing 1. The universal wheel 9 and the top of the mold temperature housing 1 are connected through a fixing member, ensuring the stability of the wheels during rolling and preventing them from falling off, guaranteeing the overall stability and safe use.

[0030] The working principle provided by the present utility model is as follows: When the present utility model is specifically implemented, when it is detected that the temperature rise of the fuel tank 2 is higher than the threshold value, the water tank 3 delivers the internal water to the water delivery pipe 4. The water flow in the water delivery pipe 4 contacts the heat-conducting sheet 5 after flowing, and contacts the fuel tank 2 through the heat-conducting sheet 5, taking away the heat of the fuel tank 2 and finally returning to the water tank 3 to complete the heat and cold exchange.
