Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an injection molding device for vacuum cleaner parts that prevents molten material from sticking together. Background Technology

[0002] The main components of a vacuum cleaner include a motor, which is the core component. Its high-speed rotation generates powerful suction, drawing air and dust into the vacuum cleaner. There is also a dust bag or dustbin to collect the sucked-in dust and debris, preventing it from being released again. In the manufacturing process, injection molding is often used. In this device, the injection molding machine uses a screw to transport granular plastic raw material to a heated barrel, where it is melted and liquefied. Then, under high pressure, the molten plastic is rapidly injected into the mold cavity. The mold design is tailored to the shape, size, and structural characteristics of different vacuum cleaner parts, precisely shaping the part's form. However, during use, the molten material can easily stick to the mold surface, leading to injection molding failure.

[0003] The anti-molten material adhesion mechanism mainly consists of demolding components, bolts, and a fan. The surface of these components is specially treated to have an extremely low coefficient of friction. After the molten plastic cools and solidifies in the mold cavity, these demolding components can effectively reduce the adhesion between the molten material and the inner wall of the mold, allowing the molded parts to be easily removed from the mold. This greatly reduces the damage and deformation of parts caused by molten material adhesion. The anti-molten material adhesion mechanism is also equipped with an air blowing auxiliary system. During the demolding process, the air blowing system will be activated in a timely manner to blow high-pressure gas into the contact area between the mold cavity and the part. However, under long-term use, the demolding mechanism will wear down, and the air duct will easily become blocked, which will reduce the demolding effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an injection molding device for vacuum cleaner parts that prevents molten material from sticking together. It aims to improve the problem that in the prior art, the demolding mechanism will wear down and the air duct will be easily blocked after long-term use, which will reduce the demolding effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum cleaner part injection molding device for preventing molten material adhesion, comprising a fixed mold, an injection head fixedly connected to the right side of the fixed mold near the middle, a connecting pipe fixedly connected to the right side of the injection head, a square box connected to the right side of the connecting pipe, multiple sliding grooves fixedly connected to the front and rear sides of the interior of the square box, square baffles slidably connected to the interior of each of the multiple sliding grooves, an extrusion plate fixedly connected to the top of the square baffles, multiple limiting posts slidably connected to the outer wall of the extrusion plate, a second spring slidably connected to the outer wall of the limiting posts, the bottom of the second spring being fixedly connected to the top of the square box, a second elongated groove being provided on the top of the square box, and a connecting mechanism being provided on the top of the fixed mold for fixing and connecting.

[0006] As a further description of the above technical solution:

[0007] The connecting mechanism includes multiple round buckles, each of which is fixedly connected to the front and rear sides of the fixed mold. A rotating buckle is slidably connected to the outer wall of each round buckle. A long groove is formed inside the rotating buckle. Multiple circular holes are formed on the left and right sides of the top of the fixed mold. A spring is fixedly connected to the inner wall of each circular hole, and a connecting post is slidably connected to the outer wall of each spring.

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

[0009] The right side of the square box is connected to a liquid storage tank, and the top of the liquid storage tank is connected to a water injection hole.

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

[0011] A rear cover plate is fixedly connected to the right side of the liquid storage tank, and bolts are threaded to both the upper and lower ends of the right side of the rear cover plate.

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

[0013] The bottom of the liquid storage tank is fixedly connected to a base one, and the left side of the base one is fixed; a base two is also connected to it.

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

[0015] The fixed mold has a circular hole on its right side and a mold groove on its top.

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

[0017] Each of the connecting columns is fixedly connected to a moving mold, and the top of each moving mold is provided with multiple vent holes. The top of the moving mold is connected to a feed port.

[0018] As a further description of the above technical solution:

[0019] The top of the second base is fixedly connected to an outer baffle, and the outer wall of the outer baffle is fixedly connected to multiple reinforcing ribs.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, before injection molding, a release agent is first added to the inside through the water injection hole. Then, the extrusion plate is pulled upward. At this time, the extrusion plate will move upward, and at the same time, it will drive the square baffle to move upward. Simultaneously, the extrusion plate will drive the spring two to move upward along the limiting post. At this time, the square baffle will pass through the long groove two on the square box, and then be injected into the inside of the mold groove through the injection head. At this time, the inner wall of the mold groove is filled with release agent, which realizes the function of spraying release agent in advance before injection molding to prevent the molten material from sticking together.

At this time, the rotating buckle will be engaged in the round buckle. At the same time, the moving mold is pressed down and slides along the connecting column, which will compress the spring. This achieves the function of fixing the fixed mold and the moving mold, making the overall injection molding more stable. Attached Figure Description

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The fixed mold 1 has a circular hole 16 on the right side and a mold groove 17 on the top. The top of the multiple connecting columns 205 are all fixedly connected to the moving mold 18 to facilitate injection molding. The top of the moving mold 18 has multiple vent holes 20 and the top of the moving mold 18 is connected to the feed port 21. The top of the base 24 is fixedly connected to the outer baffle 23, which serves as a shield.

[0038] Specifically, a circular hole 16 is opened on the right side of the fixed mold 1. The top area of ​​the fixed mold 1 is also finely processed to form a mold groove 17. The mold groove 17 is designed to better cooperate with the moving mold 18. Multiple connecting pillars 205 are used to support and fix the moving mold 18. The top of each of these connecting pillars 205 is fixedly connected to the moving mold 18, ensuring the stability and precise position of the moving mold 18.

[0039] Working principle: Before injection molding, release agent is first added to the inside through the water injection hole 19. Then, the extrusion plate 8 is pulled upward. At this time, the extrusion plate 8 will move upward, and at the same time, the square baffle 7 will move upward. Simultaneously, the extrusion plate 8 will drive the spring 10 to move upward along the limit post 9. At this time, the square baffle 7 will pass through the long groove 11 on the square box 5. Then, the square baffle 7 will move upward along the slide 6. At the same time, the channel inside the square box 5 opens, and the release agent enters the square box 5 and the connecting pipe 4. Then, it is injected into the mold groove 17 through the injection head 3. At this time, the inner wall of the mold groove 17 is filled with release agent. Then, the extrusion plate 8 is released. Under the restoring force of the spring 10, the square baffle 7 will slide down along the inner wall of the slide 6. At this time, the channel inside the square box 5 is closed, and then injection molding is performed. This achieves the effect of spraying release agent in advance before injection molding to prevent the molten material from sticking together.

[0040] When connection is required, firstly, the rotating buckle 202 on the moving mold 18 is engaged with the round buckle 201 of the fixed mold 1. At this time, the rotating buckle 202 will be engaged inside the round buckle 201. Simultaneously, the moving mold 18 is pressed down and slides along the connecting post 205, which will compress the spring 204, causing the spring 204 to deform. When the moving mold 18 is completely pressed against the top of the fixed mold 1, the spring 204 will be squeezed into the round hole 203, thus achieving a fixed connection between the fixed mold 1 and the moving mold 18, making the overall injection molding more stable.
