Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically to an injection mold structure with high-efficiency cooling. Background Technology

[0002] Injection molds are crucial molding equipment in the plastics processing industry, and their performance directly affects the quality of plastic products and production efficiency. Temperature control of the mold is paramount during injection molding. Appropriate mold temperature can improve the fluidity of the molten plastic, enhance the molding quality of the finished product, and shorten the molding cycle.

[0003] However, existing injection molds have some shortcomings in temperature control. For example, the distribution of cooling channels is not reasonable enough, resulting in uneven mold temperature and affecting the molding accuracy of the product; the cooling system control is not intelligent enough, unable to adjust in real time according to the actual state of the mold and production needs, easily leading to low cooling efficiency or energy waste. In addition, during mold opening and closing, the inability to properly control the cooling water flow rate and the opening and closing of cooling channels may cause the injected plastic to fail to reach the cavity, resulting in blockage, affecting the continuity of production and the quality of the product.

[0004] Therefore, it is of great significance to provide an efficient cooling injection mold structure to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an injection mold structure with high efficiency cooling to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency cooling injection mold structure includes an upper mold plate and a lower mold plate. The bottom end of the upper mold plate is provided with a mold cavity, and the top end of the lower mold plate is provided with a punch. An injection cavity is opened at the bottom end of the lower mold plate. A temperature sensor is installed on the side of the mold cavity. Multiple cooling channels one and two are evenly distributed on the side of the mold cavity. The cooling channels one and two are spaced apart and arranged in parallel.

[0007] The inlet end of the first cooling channel is connected via connecting pipe four, and the outlet end of the first cooling channel is connected via connecting pipe one; the inlet end of the second cooling channel is connected via connecting pipe three, and the outlet end of the second cooling channel is connected via connecting pipe two.

[0008] The outlet end of the connecting pipe 2 is connected to the return water pipe 2, and the outlet end of the connecting pipe 1 is connected to the return water pipe 1; the inlet end of the connecting pipe 3 is equipped with a solenoid valve 1, and the inlet end of the solenoid valve 1 is equipped with a water pump 2; the inlet end of the connecting pipe 4 is equipped with a solenoid valve 2, and the inlet end of the solenoid valve 2 is equipped with a water pump 1; both the water pump 1 and the water pump 2 are adjustable speed water pumps.

[0009] A distance sensor is installed on the side of the upper template.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting parallel cooling channels one and two at intervals on the side of the mold cavity, uniform cooling of the mold cavity can be achieved, improving the consistency of mold temperature and thus improving the molding accuracy of the product.

[0011] 2. Temperature sensors monitor the mold cavity temperature in real time, and distance sensors detect the mold status. Combined with solenoid valves and adjustable-speed water pumps, intelligent control of the cooling system is achieved. During mold closing, the system automatically accelerates the cooling water flow rate and opens dual cooling channels for rapid cooling and molding, shortening the molding cycle and improving production efficiency. During mold opening, the cooling water flow rate is reduced, and one of the cooling channels is closed to maintain a suitable mold cavity temperature. This prevents the injected plastic from becoming too cold to reach the cavity, thus avoiding blockages and ensuring continuous production and product quality.

[0021] Please see Figure 1-2 This utility model provides a technical solution for a highly efficient cooling injection mold structure: An efficient cooling injection mold structure includes an upper mold plate 1 and a lower mold plate 2. The bottom end of the upper mold plate 1 is provided with a mold cavity 5, the top end of the lower mold plate 2 is provided with a punch 4, and the bottom end of the lower mold plate 2 is provided with an injection cavity 3. The punch 4 and the mold cavity 5 cooperate to form the injection cavity 3 for injection molding.

[0022] Temperature sensors 8 are installed on the sides of the mold cavity 5 to monitor the temperature of the mold cavity 5 in real time and transmit the temperature signal to the intelligent control system. Multiple cooling channels 1 6 and 2 7 are evenly distributed on the sides of the mold cavity 5. The cooling channels 1 6 and 2 7 are spaced apart and arranged in parallel. This distribution method allows the coolant to flow evenly around the mold cavity 5, achieving uniform cooling of the mold cavity 5.

[0023] The inlet of cooling channel 16 is connected via connecting pipe 4 18, and the outlet is connected via connecting pipe 1 13; the inlet of cooling channel 2 7 is connected via connecting pipe 3 17, and the outlet is connected via connecting pipe 2 10. The outlet of connecting pipe 2 10 is connected to return water pipe 2 11, and the outlet of connecting pipe 1 13 is connected to return water pipe 1 15, for returning the cooled coolant to the external coolant recovery device.

[0024] A solenoid valve 12 is installed at the inlet end of connecting pipe 3 17, and a water pump 2 19 is installed at the inlet end of solenoid valve 12; a solenoid valve 2 14 is installed at the inlet end of connecting pipe 4 18, and a water pump 16 is installed at the inlet end of solenoid valve 2 14. Both water pump 16 and water pump 2 19 are adjustable speed water pumps. The intelligent control system controls the opening and closing of solenoid valve 12 and solenoid valve 2 14, as well as the speed of water pump 16 and water pump 2 19, to achieve independent control of cooling channel 1 6 and cooling channel 2 7.

[0025] A distance sensor 9 is installed on the side of the upper template 1 to detect the mold closing status of the upper template 1 and the lower template 2, that is, to detect whether the mold is completely closed.

[0026] Working principle: During the injection molding process, when the distance sensor 9 detects the mold closing, it sends a mold closing signal to the intelligent control system. After receiving the signal, the control system controls the opening of solenoid valve 12 and solenoid valve 14, and simultaneously increases the speed of water pump 16 and water pump 19, so that cooling channel 6 and cooling channel 7 work simultaneously, accelerating the cooling water flow rate, rapidly cooling the mold cavity 5, promoting the molding of the plastic melt, and shortening the molding cycle.

[0027] When the distance sensor 9 detects that the mold is opening, it sends an opening signal. The control system controls one of the solenoid valves to close (for example, closing solenoid valve 12 to stop the cooling channel 7 from working), and at the same time reduces the speed of water pump 16 to reduce the cooling water flow rate, so as to maintain a suitable temperature in the mold cavity 5 and avoid blockage caused by the plastic not being able to reach the cavity due to excessively low temperature.

[0028] Temperature sensor 8 monitors the temperature of mold cavity 5 in real time and feeds the temperature signal back to the control system. The control system can further adjust the speed of the water pump and the opening and closing of the solenoid valve according to the temperature, so as to achieve precise control of the mold cavity temperature and ensure the stability and efficiency of the injection molding process.

[0029] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
