Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding system. Background Technology

[0002] With industrial development, various production activities increasingly rely on mechanical equipment, such as injection molding machines. Injection molding is a method of shaping industrial products. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. The mold is usually cooled by water to accelerate the injection rate, and then the molded products are transported away through an assembly line. The equipment used to cool the mold by water is called a chiller. A chiller, also known as a freezer or water cooler, works on the principle of refrigeration systems. Low-temperature, low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs heat from the water and evaporates into a low-temperature, low-pressure gaseous state.

[0003] During evaporation, the refrigerant temperature remains constant. The low-temperature, low-pressure gaseous refrigerant enters the compressor, where it is compressed into a high-temperature, high-pressure gaseous state. It then enters the condenser, where it exchanges heat with the ambient medium. Some of the heat from the high-temperature, high-pressure gaseous state is absorbed by the medium, causing its temperature to rise. The refrigerant releases heat, transforming into a high-temperature, high-pressure liquid in the condenser. The condenser temperature remains constant during this process. The refrigerant then enters the expansion valve for throttling, a rapid cooling process that transforms it into a low-temperature, low-pressure liquid. After this process, the refrigerant re-enters the evaporator for heat exchange and evaporation, thus completing the entire refrigeration system cycle. This continuous cycle ensures continuous cooling of the water, thereby improving production efficiency. However, in existing technologies, when the chiller stops due to malfunctions, the injection molding machine continues to operate. This can easily lead to defective products in the injection molded parts, resulting in a high defect rate. Utility Model Content

The chiller is used to cool the mold inside the injection molding machine and includes a first switch. The injection molding machine includes a second switch, and the first switch is coupled to the second switch for controlling the injection molding machine to stop working when the chiller malfunctions.

[0006] In one embodiment, the injection molding machine further includes a third switch spaced apart from the second switch; the injection molding system further includes a production line, the production line including a fourth switch, the third switch being coupled to the fourth switch for controlling the production line.

[0007] In one embodiment, the chiller's operating state includes a normal operating state and an abnormal operating state. The first switch includes a first contact, and the second switch includes a second contact and a third contact. In the normal operating state, the first contact and the second contact are normally closed.

[0008] In one embodiment, the third contact is normally open when the chiller is in normal operating condition.

[0009] In one embodiment, when the chiller is in an abnormal working state, the first and second contacts are normally open, and the third contact is normally closed.

[0010] In one embodiment, the assembly line further includes an assembly line motor and a motor controller. The assembly line motor is used to provide power for transporting products on the assembly line, and the motor controller is electrically connected to the assembly line motor and the fourth switch.

[0015] This invention offers the following advantages: By cooperating with a chiller and an injection molding machine, the chiller cools the mold inside the injection molding machine and includes a first switch. The injection molding machine includes a second switch, and the first and second switches are coupled together. These switches are used to control the injection molding machine to stop working when the chiller malfunctions.

Therefore, this avoids defects in the injection-molded products, improving product yield and safety. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the injection molding system of this utility model. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the protection scope of the present invention.

[0018] Please see Figure 1 This utility model provides an injection molding system, including a chiller 1, an injection molding machine 2, and a production line 3. The chiller 1 is used to cool the mold inside the injection molding machine 2, and includes a first switch K0, which includes a first electrical connection point Com0 and a first contact Y00. It is understood that the first electrical connection point Com0 is electrically connected to the controller of the chiller 1, and the controller of the chiller 1 controls the operation of the chiller 1. In one embodiment, the working principle of the chiller 1 is as follows: According to the principle of refrigeration systems, low-temperature, low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator, causing the evaporator to absorb heat from the water and evaporate into a low-temperature, low-pressure gaseous state.

[0019] During the evaporation process, the refrigerant temperature remains constant. The low-temperature, low-pressure gaseous refrigerant enters the compressor and is compressed into a high-temperature, high-pressure gaseous state. Then, it enters the condenser and exchanges heat with the medium in the room. Some of the heat from the high-temperature, high-pressure gaseous state is absorbed by the medium, causing the medium temperature to rise. The refrigerant releases heat and the condenser becomes a high-temperature, high-pressure liquid.

[0020] The condenser process maintains a constant temperature, then the refrigerant enters the expansion valve for throttling. Throttling is a rapid cooling process, turning the refrigerant into a low-temperature, low-pressure liquid. After this process, the refrigerant enters the evaporator for heat exchange and evaporation, thus completing the entire process of the refrigeration system. This cycle is continuous, allowing water to be continuously cooled, thereby improving production efficiency.

[0021] Injection molding machine 2 includes a second switch K1 and a third switch K2, with the third switch K2 spaced apart from the second switch K1. A first switch K0 is coupled to the second switch K1 and is used to control the injection molding machine 2 to stop working when the chiller 1 malfunctions. The second switch K1 includes a second electrical connection point Com1, a second contact Y01, and a third contact Y02. The chiller 1's operating states include normal operating state and abnormal operating state.

[0022] Under normal operating conditions, the first contact Y00 and the second contact Y01 are normally closed, and the third contact Y02 is normally open when the chiller 1 is in normal operating condition. That is, the first contact Y00 is electrically connected to the first electrical connection point Com0, and the second contact Y01 is electrically connected to the second electrical connection point Com1. When the chiller 1 is in an abnormal operating state, the first contact Y00 and the second contact Y01 are normally open, and the third contact Y02 is normally closed. That is, the third contact Y02 is electrically connected to the second electrical connection point Com1. At this time, the injection molding machine 2 is shut down. In other words, when the chiller 1 malfunctions, the signals of the first switch K0 and the second switch K1 are linked to drive the injection molding machine 2 to shut down, thereby protecting the injection molding machine 2. The third switch K2 includes the third electrical connection point Com2, the fourth contact Y05, and the fifth contact Y06. It can be understood that the second electrical connection point Com1 and the third electrical connection point Com2 are electrically connected to the controller of the injection molding machine 2, and the controller of the injection molding machine controls the operation of the injection molding machine.

[0023] The injection molding system also includes a production line 3, which includes a fourth switch K3 and a fifth switch K4, a production line motor M, and a motor controller U. The third switch K2 is coupled to the fourth switch K3 to control the production line 3. That is, when the injection molding machine 2 is operating, the production line 3 is controlled by the signals from the third switch K2 and the fourth switch K3, eliminating the need for manual control. The production line motor M provides power to the production line 3 for transporting products. The motor controller U is electrically connected to the production line motor M and the fourth switch K3. The fifth switch K4 is electrically connected to the motor controller U and is used to control the electrical energy input to the motor controller U.

[0024] Production line 3 also includes a sixth switch K5 and a fuse Fu. The sixth switch K5 is electrically connected to the fifth switch K4 and is used to control the electrical energy input to the fifth switch K4. In other words, the sixth switch K5 can independently control whether production line 3 operates. The fourth switch K3 is electrically connected to the signal input terminal of the fifth switch K4 via the fuse Fu, which provides overcurrent protection, thereby improving safety. It is understood that the first to sixth switches can be relays.

[0025] In summary, this invention utilizes the cooperation between a chiller 1 and an injection molding machine 2. The chiller 1, used to cool the mold inside the injection molding machine 2, includes a first switch K0. The injection molding machine 2 includes a second switch K1, which is coupled together to control the injection molding machine 2 to stop working when the chiller 1 malfunctions. In other words, during the operation of both the chiller 1 and the injection molding machine 2, if the chiller 1 fails to cool the mold inside the injection molding machine 2, the coupling effect of the first switch K0 and the second switch K1 will control the injection molding machine 2 to stop working. Therefore, this avoids defective products molded by the injection molding machine 2, improving product yield and safety.
