Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner brush injection mold technology with guiding function, and in particular to a vacuum cleaner brush injection mold with guiding function. Background Technology

[0002] In the injection molding production of vacuum cleaner brushes, the performance of the injection mold plays a decisive role in product quality and production efficiency. However, traditional vacuum cleaner brush injection molds have many drawbacks, which seriously restrict the further development of the industry.

[0003] In terms of guidance, traditional molds have rudimentary guiding structures, typically relying on simple locating pins or crude slides. During mold opening and closing, this guiding method struggles to ensure precise alignment between the moving and fixed molds, leading to increased mold wear and shortened mold lifespan. Furthermore, positioning deviations make it difficult to guarantee the dimensional accuracy of injection-molded vacuum cleaner brushes, affecting the brush's compatibility with the vacuum cleaner and reducing product quality.

[0004] The demolding process also presents significant problems. Traditional molds have complex and inefficient demolding mechanisms, often requiring manual assistance. This not only increases labor costs and extends the production cycle but also easily damages the brushes during demolding, leading to a higher product scrap rate. Due to uneven distribution of demolding force, some brushes may exhibit defects such as deformation and bending, failing to meet the market's demand for high-quality vacuum cleaner brushes. A vacuum cleaner brush injection mold with a guiding function is needed to solve these problems. Utility Model Content

Due to uneven distribution of demolding force, some brushes may exhibit defects such as deformation and bending, failing to meet the market's demand for high-quality vacuum cleaner brushes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum cleaner brush injection mold with guiding function, including an upper mold, the upper mold having a sprue, a guide post fixedly connected to the bottom of the upper mold, a movable mold plate slidably connected to the outer wall of the guide post, a support plate slidably connected to the lower section of the guide post, a movable mold base plate at the bottom of the support plate, a pull rod fixedly connected to the top of the inner wall of the movable mold base plate, a push plate guide post fixedly connected to the top of the movable mold base plate, a return spring fixedly connected to the top of the movable mold base plate, a fixed mold plate fixedly installed at the bottom of the upper mold, an inclined guide post fixedly connected to the bottom of the upper mold, a slider fixedly connected to the outer wall of the inclined guide post, a ejector block fixedly installed at the top of the middle section of the movable mold plate, a sliding block slidably connected to the outer wall of the inclined guide post, a sliding rod fixedly connected to the outer end of the sliding block, a connecting spring sleeved on the outer wall of the sliding rod, a limit ring fixedly installed on the outer wall of the movable mold plate, and a connecting pipe connected to the outer wall of the movable mold plate.

[0007] A further improvement is that the limiting ring is fixedly installed on the outer wall of the upper mold, and the limiting rings are symmetrically arranged; during the injection molding process, the gas generated in the mold can be discharged through the connecting pipe to prevent the gas from accumulating in the mold and forming bubbles or air marks, thus ensuring the quality of the injection molded parts; the slide rod is slidably connected to the outer wall of the fixed plate that is fixedly connected to the outer wall of the moving mold plate, and the connecting spring sleeved on the outer wall of the slide rod can adjust the size of the exhaust channel to a certain extent to ensure smooth exhaust.

[0008] A further improvement is that the pulling rod is slidably connected to the bottom outer wall of the moving template.

[0009] A further improvement is that the bottom outer wall of the moving template is slidably connected to the outer wall of the push plate guide post; the support plate slidably connected to the lower section of the guide post further enhances the stability of the mold structure and prevents the moving template from shaking during movement; the limiting ring is fixedly installed on the outer wall of the upper mold and is symmetrically arranged, which can limit the movement range of the moving template and avoid excessive movement that could damage the mold.

[0010] A further improvement is that the top of the reset spring is supported by the bottom of the moving mold plate; the pull rod fixedly connected to the top of the inner wall of the moving mold base plate can pull the injection molded part during demolding to help it detach from the fixed mold plate; the pull rod is slidably connected to the bottom outer wall of the moving mold plate to ensure smooth material pulling; the push plate guide post fixedly connected to the top of the moving mold base plate provides guidance for the movement of the moving mold plate.

[0011] A further improvement is that the sliding block is slidably connected to the inner wall of the limiting groove of the moving template; the upper mold is connected to the sprue for injecting plastic raw materials into the mold cavity; the fixed template is fixedly installed at the bottom of the upper mold, and together with the moving template, they form the injection cavity; during the injection process, the slider and sliding block on the outer wall of the inclined guide post work together to adjust the shape and size of the mold cavity according to the injection process requirements, so as to ensure the precise forming of the vacuum cleaner brush.

[0012] A further improvement is that the slide rod is slidably connected to the outer wall of the fixed plate that is fixedly connected to the outer wall of the moving template, and the other end of the connecting pipe is connected to the support plate for venting; the slide rod is slidably connected to the outer wall of the fixed plate that is fixedly connected to the outer wall of the moving template, and the connecting spring sleeved on the outer wall of the slide rod can adjust the size of the venting channel to a certain extent to ensure smooth venting.

[0013] By employing the above technical solution, this utility model provides a vacuum cleaner brush injection mold with a guiding function, which has at least the following beneficial effects:

[0014] 1. This utility model's injection mold utilizes guide pillars fixedly connected to the bottom of the upper mold to provide stable and precise guidance for the movement of the moving mold plate. During mold opening and closing, the moving mold plate slides smoothly along the guide pillars, and the limiting ring restricts the movement range of the moving mold plate, ensuring precise alignment between the moving mold and the fixed mold. This design effectively avoids dimensional deviations caused by mold misalignment, reliably guaranteeing the dimensional accuracy of the injection-molded vacuum cleaner brush, greatly improving the compatibility between the brush and the vacuum cleaner, reducing the scrap rate caused by dimensional discrepancies, and laying a solid foundation for the production of high-quality vacuum cleaner brushes.

[0015] 2. The demolding and venting design of this utility model mold significantly improves production efficiency. During demolding, the pull rod on the top of the inner wall of the moving mold base plate and the push plate guide post work together. The pull rod pulls the injection molded part away from the fixed mold plate, and the moving mold plate moves smoothly along the push plate guide post, achieving efficient demolding, reducing manual intervention, and shortening the production cycle. At the same time, the connecting pipe connected to the outer wall of the moving mold plate promptly discharges the gas generated in the mold, preventing the formation of air bubbles and air marks. This not only improves the appearance quality of the product but also avoids the impact of gas accumulation on brush performance, comprehensively improving production quality and efficiency.
