Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, and more specifically, to a sampling port for an injection molding machine. Background Technology

[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 one cycle of an injection molding machine, a certain amount of plastic is heated and plasticized within a specified time, and then injected into the mold cavity through a screw under certain pressure and speed. After injection, the molten material injected into the mold cavity is kept in a fixed shape.

[0003] Based on the above, the inventors have discovered that existing injection molding production generates harmful gases. Therefore, injection molding is carried out in a sealed environment, resulting in the absence of a sampling port at the product outlet. However, during the production process, it is necessary to sample the product to test whether its various physical and chemical indicators meet the standards. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a sampling port for injection molding machines, aiming to achieve a more practical purpose.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 A sampling port for an injection molding machine includes an injection chamber 1, a bracket 2 fixedly connected to the upper front end of the injection chamber 1, a sampling window 3 snapped into the lower part of the bracket 2, a sampling frame 4 fixedly connected to the middle front end of the injection chamber 1, a material unloading rack 5 disposed at the upper part of the interior of the injection chamber 1, and a conveying rack 6 disposed at the lower part of the interior of the injection chamber 1, with an adjustment mechanism 7 disposed at the front end of the opposite side of the material unloading rack 5 and the conveying rack 6.

[0025] The adjustment mechanism 7 includes a drive motor 9, an adjustment rod 10 is fixedly connected to the output end of the drive motor 9, a guide plate 11 is fixedly connected to one end of the adjustment rod 10, and support rods 12 are movably connected to both sides of the rear end of the guide plate 11. The adjustment mechanism 7 is provided in order to adjust the feeding angle of the product and facilitate sampling and inspection by the staff.

[0026] See Figure 1 Hinges are provided at both ends of the connection between the bracket 2 and the sampling window 3. The two sides of the hinges are fixedly connected to the bottom of the bracket 2 and the top of the sampling window 3, respectively, so that the opening and closing of the sampling window 3 can be easily adjusted through the hinges.

[0027] See Figure 2 The front ends of the hanger 2, sampling window 3, and sampling frame 4 are all transparent, allowing direct observation of the product processing inside the injection molding chamber 1 through the transparent windows.

[0028] See Figure 2 Two hanging chains 8 are fixedly connected to the lower center of the sampling window 3. The hanging chains 8 are snapped into the top surface of the sampling frame 4. The sampling window 3 is limited and fixed by the hanging chains 8 to prevent the sampling window 3 from shaking.

[0029] See Figure 3 The drive motor 9 is located at the front end of the injection chamber 1 on one side, and the drive motor 9 is fixedly connected to the injection chamber 1. When the drive motor 9 is started, the guide plate 11 is rotated upward under the action of the adjusting rod 10, so that the front end of the guide plate 11 is above the sampling frame 4. Then the sample conveyed by the unloading rack 5 falls into the sampling frame 4 through the guide plate 11.

[0030] See Figure 1The guide plate 11 is located in the center of the opposite face between the front end of the unloading rack 5 and the front end of the conveying rack 6. The top end of the support rod 12 is fixedly connected to the bottom surface of the unloading rack 5. The sample conveyed by the unloading rack 5 falls directly onto the conveying rack 6 through the guide plate 11 and is directly conveyed to the subsequent processing position.

[0031] In operation: The injection molded products produced by the injection molding machine fall onto the unloading rack 5. The product processing inside the injection molding chamber 1 can be directly observed through the transparent window. The unloading rack 5 transports samples through the guide plate 11 to the conveyor rack 6, and then transports them to the subsequent processing position. When sampling inspection of the injection molded products is required, the drive motor 9 is started, and the guide plate 11 is rotated upward under the action of the adjusting rod 10, so that the front end of the guide plate 11 is above the sampling frame 4. Then the sample transported by the unloading rack 5 falls into the sampling frame 4 through the guide plate 11. The support rod 12 ensures the rotational stability of the guide plate 11. At the same time, the hanging chain 8 is removed, and then the sampling window 3 is opened to take out the sample for inspection. After the inspection is completed, the sampling window 3 is closed, and the hanging chain 8 is re-engaged with the top surface of the sampling frame 4. The hanging chain 8 limits and fixes the sampling window 3 to prevent the sampling window 3 from shaking, ensuring the airtightness of the injection molding chamber 1 and reducing the leakage of harmful gases.
