Description

Technical Field

[0001] This utility model belongs to the field of molding die technology, and in particular relates to a vacuum cleaner tube molding die that facilitates material unloading. Background Technology

[0002] Vacuum cleaner hose forming molds are key tools used in manufacturing vacuum cleaner hoses, and their design directly affects product quality, production efficiency, and cost.

[0003] Currently, vacuum cleaner hoses are usually made using plastic injection molding. Due to the long length, thin wall thickness, and hollow interior of the hose, after molding, the excessive length of the hose increases the friction on one side during demolding, significantly increasing the resistance to material removal. This can cause the product to fail to detach smoothly from the core, and even result in quality problems such as deformation and scratches during demolding. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that vacuum cleaner tubes are usually made of plastic injection molding process. Due to the long length of the tube, the thin wall thickness and the hollow interior, the friction on one side increases during demolding because of the excessive length of the tube. This significantly increases the resistance to material removal, which makes it difficult for the product to be smoothly removed from the core. In some cases, the product may even deform or scratch during demolding. Therefore, this utility model proposes a vacuum cleaner tube molding mold that facilitates material removal.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vacuum cleaner tube forming mold that facilitates material unloading, comprising:

[0006] A workbench is provided with a lower mold and several hydraulic cylinders. The lower mold is provided with several first grooves. The hydraulic cylinders are slidably connected to the workbench and are provided with several forming rods.

[0007] The upper mold has a punch platform at its bottom, and a plurality of second grooves are provided on the punch platform. The first groove, the second grooves and the forming rod form a forming groove. The upper mold has a pouring hole.

[0008] As a further description of the above technical solution:

[0009] Several hydraulic cylinders are located on both sides of the lower mold. Each hydraulic cylinder is equipped with a sealing plate. Several forming rods are connected to the sealing plate. During casting, the sealing plate abuts against the outer wall of the first groove and the second groove.

[0010] As a further description of the above technical solution:

[0011] A linear motor is installed on the workbench, and the bottom of the hydraulic cylinder is connected to the linear motor.

[0012] As a further description of the above technical solution:

[0013] The forming rod on one side of the sealing plate is longer than the forming rod on the other side of the sealing plate.

[0014] As a further description of the above technical solution:

[0015] The upper mold is provided with an abutment plate, which abuts against the outer wall of the sealing plate during casting.

[0016] As a further description of the above technical solution:

[0017] The lower mold is provided with a plurality of guide sleeves, and the upper mold is provided with a plurality of guide posts, the guide sleeves and the guide posts being matched with each other.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting hydraulic cylinders on both sides of the lower mold, the hydraulic cylinders are slidably connected to a linear motor. The sealing plate is connected to the push shaft of the hydraulic cylinder, and the forming rod is connected to the sealing plate. When it is necessary to inject and mold the vacuum cleaner tube, the hydraulic cylinder pushes the sealing plate to seal the outer wall of the first groove. The upper mold moves down under the drive of the telescopic cylinder, so that the second groove and the first groove abut against each other, and the side wall abuts against the sealing plate. The forming rods on both sides abut against each other, thereby forming a forming groove between the first groove, the second groove and the forming rod. The vacuum cleaner tube is formed in the forming groove by injecting plastic material through the pouring hole. When it is necessary to unload the material after cooling, the hydraulic cylinders on both sides drive the forming rods on both sides to move backward at the same time. When the shorter forming rod on one side moves out first, only part of the vacuum cleaner tube remains on the longer forming rod. The vacuum cleaner tube is removed from the longer forming rod using a tool. This structure greatly reduces the friction force during one-sided unloading, reduces unloading resistance, and also avoids the problem of deformation and scratches on the vacuum cleaner tube during unloading due to its large size, thus improving production quality.

[0020] 2. In this utility model, the structure is provided with multiple molding grooves, which can produce and demold multiple vacuum cleaner tubes at the same time, improving production efficiency. Furthermore, an abutment plate is provided on the upper mold, which allows the abutment plate to effectively abut and position the sealing plate during casting, avoiding gaps between the sealing plate and the first and second grooves, and greatly improving the injection molding quality.

[0033] Please see Figure 1-3 This utility model provides a technical solution: a vacuum cleaner tube forming mold that facilitates material unloading, comprising:

[0034] A workbench 1 is provided with a lower mold 2 and several hydraulic cylinders 3. The lower mold 2 is provided with several first grooves 4. The hydraulic cylinders 3 are slidably connected to the workbench 1 and are provided with several forming rods 10.

[0035] The upper mold 5 has a punch 6 at its bottom, and a plurality of second grooves 7 are provided on the punch 6. The first groove 4, the second grooves 7 and the forming rod 10 form a forming groove. The upper mold 5 is provided with a pouring hole 8.

[0036] Several hydraulic cylinders 3 are located on both sides of the lower mold 2. A sealing plate 9 is provided on the hydraulic cylinder 3. Several forming rods 10 are connected to the sealing plate 9. During casting, the sealing plate 9 abuts against the outer wall of the first groove 4 and the second groove 7.

[0037] A linear motor 11 is installed on the workbench 1, and the bottom of the hydraulic cylinder 3 is connected to the linear motor 11.

[0038] The forming rod 10 on one side of the sealing plate 9 is longer than the forming rod 10 on the other side of the sealing plate 9.

[0039] The upper mold 5 is provided with an abutment plate 12, which abuts against the outer wall of the sealing plate 9 during casting.

[0041] Working principle: By setting hydraulic cylinders on both sides of the lower mold, the cylinders are slidably connected to a linear motor. The sealing plate is connected to the push shaft of the hydraulic cylinder, and the forming rod is connected to the sealing plate. When the vacuum cleaner tube needs to be injection molded, the hydraulic cylinder pushes the sealing plate to seal the outer wall of the first groove. The upper mold moves down under the drive of the telescopic cylinder, so that the second groove and the first groove abut against each other, and the side wall abuts against the sealing plate. The forming rods on both sides abut against each other, thus forming a forming groove between the first groove, the second groove, and the forming rod. The vacuum cleaner tube is formed in the forming groove by injecting plastic material through the injection hole. When the material needs to be unloaded after cooling, the hydraulic cylinders on both sides drive the forming rods on both sides to move backward at the same time. When the shorter forming rod on one side moves out first, only part of the vacuum cleaner tube remains on the longer forming rod. The vacuum cleaner tube is removed from the longer forming rod using a tool. This structure greatly reduces the friction during one-sided unloading, reduces unloading resistance, and avoids the problem of deformation and scratches on the vacuum cleaner tube during unloading due to its large size, thus improving production quality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
