Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, in particular to a pressure-stabilizing injection device for injection molding production of building blocks. Background Art

[0002] In the injection molding production of building blocks, the pressure-stabilizing injection device is a key equipment to ensure the consistency of product quality. Its performance directly affects the molding accuracy and quality stability of building blocks. The pressure-stabilizing injection device is also known as an injection molding machine or injection molding machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The screw is an important component of the injection molding machine. Its function is to convey, compact, melt, stir and pressurize the plastic. All of these are accomplished by the rotation of the screw in the barrel.

[0003] However, when the existing pressure-stabilizing injection device for injection molding production of building blocks is used, the injection device needs to use hot melting of plastic particles. However, a large amount of heat is generated during the hot melting. Since the injection device cannot use heat to preheat the plastic particles, it is not conducive to efficient resource utilization, and also leads to low hot melting efficiency of plastic particles during hot melting, resulting in incomplete hot melting of some plastic particles, thereby affecting the problem of injection pressure stabilization. For this reason, we propose a pressure-stabilizing injection device for injection molding production of building blocks. Utility Model Content

[0011] The utility model provides a pressure-stabilizing injection device for injection molding production of building blocks, which has the following beneficial effects:

[0012] This pressure-stabilizing injection device for injection molding of building blocks is equipped with a preheating box, a recovery pipe, a circulation pump and a heat exchange pipe. When using the pressure-stabilizing injection device for injection molding of building blocks, the staff adds the heat exchange liquid into the preheating box through the liquid adding pipe, and adds the plastic particles into the preparation hopper, and then starts the drive motor, which drives the conveying shaft to rotate. At this time, the plastic particles fall into the injection molding tube, and the conveying blades convey the plastic particles, and the heating sleeve emits heat to act on the injection molding tube. At this time, the heat will melt the plastic particles, and then the circulation pump will start to operate. At this time, the preheating box The heat exchange fluid in the heat exchange tube flows into the heat exchange tube through the recovery pipe, and the heat on the injection tube will heat the heat exchange fluid inside the heat exchange tube, so that the temperature of the heat exchange fluid increases, and then the heat exchange fluid enters the preheating box through the recovery pipe. As the heat exchange time increases, the heat exchange fluid inside the preheating box reaches a certain temperature. At this time, the heat exchange fluid inside the preheating box will heat the plastic particles inside the preparation hopper due to the increase in temperature, thereby preheating the plastic particles and realizing efficient use of resources. Therefore, the hot melting efficiency of the plastic particles is improved, and the hot melting of the plastic particles is made more thorough, thereby improving the injection pressure stabilization.

[0020] Furthermore, the other end of the injection tube 4 is fixedly connected to an injection head 5, and one end of the injection head 5 is fixedly connected to an injection nozzle 6. By aligning the injection nozzle 6 with the injection mold, the hot melt plastic material can be quickly injected into the injection mold.

[0021] Furthermore, the driving end of the driving motor 16 is fixedly connected to the conveying shaft 17, and the outer side of the conveying shaft 17 is fixedly connected to the conveying blade 18. By starting the driving motor 16, the driving motor 16 drives the conveying shaft 17 to rotate. At this time, the plastic particles fall into the injection tube 4, and the conveying blade 18 conveys the plastic particles.

[0022] Furthermore, a preparation hopper 12 is fixedly connected to the inner side of the preheating box 7, and the preparation hopper 12 is fixedly connected to the injection tube 4. The plastic particles can be prepared through the preparation hopper 12 so that the plastic particles can flow into the injection tube 4 for hot melting.

[0023] Furthermore, the heat exchange tube 15 is made of metal material, and the heat exchange tube 15 is installed on the outside of the injection molded tube 4. The heat exchange tube 15 made of metal material can better conduct heat, thereby ensuring the heat exchange effect.

[0025] Working principle: After the utility model is installed, first check the installation and safety protection of the utility model. When using the pressure-stabilizing injection device for injection molding of building blocks, the staff adds the heat exchange liquid into the preheating box 7 through the liquid adding pipe 8, and adds the plastic particles into the preparation hopper 12, and then starts the drive motor 16, which drives the conveying shaft 17 to rotate. At this time, the plastic particles fall into the injection tube 4, and the conveying blades 18 convey the plastic particles, while the heating sleeve 19 emits heat to act on the injection tube 4.

At this time, the heat exchange liquid in the preheating box 7 flows through the recovery pipe 13. The heat on the injection tube 4 heats the heat exchange fluid inside the heat exchange tube 15, raising the temperature of the heat exchange fluid. Then, the heat exchange fluid enters the preheating box 7 through the recovery tube 13. As the heat exchange time increases, the heat exchange fluid inside the preheating box 7 reaches a certain temperature. At this time, the heat exchange fluid inside the preheating box 7 heats the plastic particles inside the preparation hopper 12 due to the increase in temperature, so that the plastic particles can be hot-melted more quickly when entering the injection tube 4. As the plastic particles are hot-melted, the plastic material is injected into the injection mold through the injection nozzle 6. This completes the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
