Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a slanted extraction mechanism for injection molding molds of vacuum cleaners. Background Technology

[0002] A vacuum cleaner is a cleaning appliance that uses a motor to generate suction, effectively removing dust and debris from floors and furniture surfaces. However, its production often involves injection molding. The vacuum cleaner injection mold, as the core tool for producing plastic parts, directly impacts product quality and production efficiency through its design and manufacturing process. The mold body is typically made of high-quality steel, which possesses high strength and excellent wear resistance, capable of withstanding the high pressure and temperature during injection molding. This ensures the mold maintains stable performance during long-term, high-volume production. During the mold design phase, the mold structure is precisely modeled. For the complex shapes of different vacuum cleaner parts, careful design is required for the injection method, core-pulling structure, and ejection system. For example, using a three-plate mold structure with narrow gates and multi-point injection can effectively ensure that the molten plastic fills the cavity evenly. However, some angled parts cannot be directly demolded by core-pulling.

[0003] In vacuum cleaner injection molding, a common angled core-pulling mechanism consists of an angled guide post, a slider, and a clamping block. This mechanism is primarily used to handle undercut structures with a certain angle on the product, where there may be inclined grooves on the side. The angled guide post is installed in the fixed mold section. When the mold opens, the angle of the guide post drives the slider to slide in a specific direction, thus achieving a lateral core-pulling action on the undercut part of the product, ensuring the product can be smoothly removed from the mold. The design and debugging of the angled core-pulling mechanism have strict requirements. First, the angle of the guide post needs to be precisely calculated based on the specific undercut of the product. Too small an angle will result in insufficient core-pulling force, while too large an angle may affect the structural strength of the mold and the core-pulling stroke. However, this type of angled core-pulling mechanism is often fixed in place and its position cannot be adjusted, resulting in it only being compatible with a single mold and unable to perform angled core-pulling demolding for molds of different specifications. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a slanted extraction mechanism for vacuum cleaner injection molding molds, aiming to improve the problem that existing slanted extraction mechanisms can only be used in a fixed position and cannot be adjusted, resulting in only being able to adapt to a single mold and being unable to perform slanted extraction demolding for molds of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slanted ejection mechanism for a vacuum cleaner injection molding die, comprising a fixed die, a support column fixedly connected to the top left side of the fixed die, a slide rail fixedly connected to the top of the support column, a track inside the slide rail, multiple pulleys slidably connected to the inner wall of the track, a fixing block two fixedly connected between adjacent pulleys, a bolt slidably connected inside the pulley, the outer wall of the bolt being threadedly connected to the outer wall of the slide rail near the middle, a nut being threadedly connected to the rear end of the outer wall of the bolt, a connecting rod fixedly connected to the bottom of the fixing block two, a sleeve slidably connected to the outer wall of the connecting rod, and a sliding mechanism provided at the top of the fixed die, the sliding mechanism being used for pushing demolding.

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

[0007] The sliding mechanism includes a baffle plate. The bottom of the baffle plate is fixedly connected to the upper right side of the fixed mold. The baffle plate has multiple square holes inside. A sliding ring is slidably connected to the inner wall of the square holes. A fixing block is fixedly connected to the right side of the sliding ring. A spring is slidably connected to the outer wall of the fixing block. A sliding mold is slidably connected to the left side of the outer wall of the fixing block.

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

[0009] A retaining ring is fixedly connected to the upper end of the outer wall of the connecting rod, and the bottom of the retaining ring is slidably connected to the top of the sliding mold.

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

[0011] A connecting plate is fixedly connected to the upper left side of the fixed mold, and the top of the connecting plate is fixedly connected to the bottom of the support column.

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

[0013] The outer wall of the slide rail is provided with multiple circular holes, and the inner wall of each circular hole is slidably connected to the outer wall of the bolt.

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

[0015] The sliding mold has multiple handles at both the front and rear ends, and the top of the sliding mold is connected to the feed port.

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

[0017] The top of the fixed mold has multiple circular holes, and the inner wall of the circular holes is slidably connected to the bottom of the sliding mold.

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

[0019] The fixed mold is fixedly connected with reinforcing ribs on all four sides, and the bottom of each of the reinforcing ribs is fixedly connected with a base plate.

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

[0021] 1. In this utility model, when oblique pulling is required, the connecting rod is first moved left and right. At this time, the connecting rod will drive the fixing block two to move left and right. Then, the fixing block two drives the pulley to slide along the track of the slide rail. After sliding to the appropriate position, the bolt is turned into the circular hole one on the slide rail. Then, the nut is screwed onto the outer wall of the bolt. Then, the connecting rod is inserted into the sleeve of the sliding mold. Then, the sliding mold will be blocked by the retaining ring, which realizes the function of adjusting the position of the connecting rod to adapt to different molds and different angles of oblique pulling.

[0022] 2. In this utility model, after injection molding is completed, the handle is first pulled upward. At this time, the handle drives the sliding mold to move upward. Then the sliding mold will drive the fixed block to move up and down, and at the same time drive the spring to stretch. At this time, the fixed block extends out from the inside of the sliding mold. Then the sliding ring on the fixed block will slide along the square hole on the baffle, which realizes the function of lifting the sliding mold at an angle, making it easier to demold.

The base plate 19 not only provides stable support for the entire mold system, but also protects the worktable and avoids damage to the worktable during production.

[0039] Working principle: When oblique extraction is required, firstly, the connecting rod 10 is moved left and right. At this time, the connecting rod 10 will drive the fixing block 2 9 to move left and right. Then, the fixing block 2 9 drives the pulley 8 to slide along the track 5 of the slide rail 4. After sliding to the appropriate position, the bolt 6 is turned into the circular hole 14 on the slide rail 4. Then, the nut 7 is screwed onto the outer wall of the bolt 6. Then, the connecting rod 10 is inserted into the sleeve 11 of the sliding mold 206. Then, the sliding mold 206 will be blocked by the retaining ring 12. After the injection molding is completed, the sliding mold 206 moves upward, so that the connecting rod 10 pushes out the parts on the sliding mold 206. This realizes the function of adjusting the position of the connecting rod 10 to adapt to different molds and different angles of oblique extraction.

[0040] After injection molding, first pull the handle 15 upwards. At this time, the handle 15 drives the sliding mold 206 to move upwards. Then, the sliding mold 206 will drive the fixed block 204 to move up and down, and at the same time drive the spring 205 to stretch. At this time, the fixed block 204 extends out from the inside of the sliding mold 206. Then, the sliding ring 203 on the fixed block 204 will slide along the square hole 202 on the baffle 201, which realizes the function of lifting the sliding mold 206 at an angle, making demolding more convenient.
