[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. In order for injection molding machines to produce products of various shapes, a quick mold change device is usually used to change the molds to meet different processing requirements.

[0003] In traditional injection molding production, molds are typically fixed directly to the fixed platen of the injection molding machine using numerous bolts. This method has several drawbacks: First, the process of installing and removing bolts is cumbersome, time-consuming, and labor-intensive. Each mold change requires operators to repeatedly tighten and loosen bolts using specialized tools, resulting in excessive downtime and severely hindering production efficiency and equipment utilization. Second, the positioning accuracy of the mold is difficult to guarantee, relying mainly on the operator's experience for manual alignment, which is prone to installation deviations and affects the stability of product quality. Therefore, a quick mold change device for injection molding machines that facilitates positioning and installation is needed to solve this problem. Utility Model Content

[0004] This invention proposes a quick mold change device for injection molding machines that facilitates positioning and installation. Through the synergistic effect of positioning and fixing components, it achieves rapid, accurate positioning and firm fixation of the mold.

[0005] This utility model is implemented as follows: a quick mold changing device for injection molding machines that is easy to position and install includes a fixed template and a mounting base. The upper end face of the fixed template is provided with a mold cavity. A positioning component and a fixing component are provided between the fixed template and the mounting base. The positioning component includes two guide rails fixedly connected to the left and right sides of the inner wall of the mold cavity, and two slide blocks fixedly connected to the left and right sides of the outer wall of the mounting base, wherein the slide blocks and the guide rails are slidably connected; The fixing component includes a second electromagnetic plate embedded in the bottom of the inner wall of the mold cavity, and a first electromagnetic plate embedded in the bottom of the mounting base, wherein the first electromagnetic plate and the second electromagnetic plate attract each other.

[0006] As a preferred embodiment of the quick mold changing device for injection molding machines that facilitates positioning and installation according to this utility model, positioning posts are fixedly connected to the four corners of the bottom end of the mounting base, and positioning holes adapted to the positioning posts are opened at the four corners of the upper end face of the fixed template.

[0017] Please see Figure 1-3 A quick mold change device for injection molding machines that is easy to position and install includes a fixed template 1 and a mounting base 3. A mold cavity 101 is opened on the upper end face of the fixed template 1. A positioning component and a fixing component are provided between the fixed template 1 and the mounting base 3. The positioning assembly includes two guide rails 201 fixedly connected to the left and right sides of the inner wall of the mold cavity 101, and two slide blocks 302 fixedly connected to the left and right sides of the outer wall of the mounting base 3. The slide blocks 302 and the guide rails 201 are slidably connected. The fixing assembly includes a second electromagnetic plate 5 embedded in the bottom of the inner wall of the mold cavity 101, and a first electromagnetic plate 4 embedded in the bottom of the mounting base 3. The first electromagnetic plate 4 and the second electromagnetic plate 5 attract each other.

[0018] In this embodiment: During injection molding machine operation, the fixed template 1 is fixed to the main body of the injection molding machine, and the mounting base 3 is used to install the mold. When it is necessary to change the mold, the operator slides the mounting base 3 along the guide rail 201 via the slide block 302 and pushes it into the mold cavity 101 until the mounting base 3 is fully in place. Subsequently, the first electromagnetic plate 4 and the second electromagnetic plate 5 are energized and attracted (or de-energized and attracted according to the design), tightly fixing the mounting base 3 to the fixed template 1. The entire process requires no complicated tools and can be completed in just a few minutes, significantly reducing downtime and improving production efficiency.

[0019] As a technical optimization of this utility model, positioning posts 301 are fixedly connected to the four corners of the bottom end of the mounting base 3, and positioning holes 2 that are adapted to the positioning posts 301 are opened at the four corners of the upper end face of the template 1.

[0020] In this embodiment: when the mounting base 3 slides along the guide rail 201 and approaches the bottom of the mold cavity 101, the positioning pin 301 will automatically insert into the positioning hole 2 on the fixed template 1. Through the cooperation of the positioning pin 301 and the positioning hole 2, an additional precise positioning function is provided to ensure that the mounting base 3 will not shift or rotate during the installation process, thereby improving the centering accuracy of the mold.

[0021] As a technical optimization of this utility model, ball bearings are installed on both the front and rear sides of the inner wall of the slide block 302, and the guide rail 201 is provided with a slide track 202 that cooperates with the ball bearings.

[0022] In this embodiment: when the operator pushes the mounting base 3, the balls in the slide 302 roll on the slide 202 of the guide rail 201, achieving smooth movement, reducing the sliding friction between the slide 302 and the guide rail 201, and making the sliding of the mounting base 3 smoother and less strenuous.

[0023] As a technical optimization of this utility model, the first electromagnetic plate 4 and the second electromagnetic plate 5 are both power-off adsorption type electromagnetic plates, and are electrically connected to the control system of the injection molding machine.

[0024] In this embodiment, automated control is achieved by electrically connecting the power-off adsorption type electromagnetic plate with the control system. The electromagnetic plate can be remotely operated to attract and release according to production needs, further improving mold changing efficiency and integration level.

[0025] As a technical optimization of this utility model, the mating surfaces of the guide rail 201 and the slide 302 are coated with a wear-resistant coating.

[0026] In this embodiment, the sliding surfaces of the guide rail 201 and the slide block 302 are coated with a polytetrafluoroethylene (PTFE) or ceramic-based wear-resistant coating. The wear-resistant coating effectively reduces the wear of the guide rail 201 and the slide block 302 during frequent sliding, improves the durability and reliability of the components, and extends the service life of the overall device.

[0027] The working principle and usage process of this utility model are as follows: During the operation of the injection molding machine, the fixed template 1 is fixed on the main body of the injection molding machine, and the mounting base 3 is used to install the mold. When it is necessary to change the mold, the operator slides the mounting base 3 along the guide rail 201 via the slide block 302 and pushes it into the mold cavity 101. When the mounting base 3 slides along the guide rail 201 and approaches the bottom of the mold cavity 101, the positioning pin 301 will automatically insert into the positioning hole 2 on the fixed template 1. Through the cooperation of the positioning pin 301 and the positioning hole 2, an additional precise positioning function is provided to ensure that the mounting base 3 will not shift or rotate during the installation process until the mounting base 3 is fully in place. Subsequently, the first electromagnetic plate 4 and the second electromagnetic plate 5 are energized and attracted (or de-energized and attracted according to the design), which tightly fixes the mounting base 3 on the fixed template 1.
