Description

Technical Field

[0001] This utility model relates to the field of dust cover blowing demolding technology, specifically a dust cover blowing demolding device. Background Technology

[0002] In industrial production, dust covers are widely used as important protective components on various equipment. The manufacturing process of dust covers typically employs injection molding. After molding, there is often a significant adhesion between the dust cover and the mold, making demolding difficult. Traditional demolding methods mainly rely on manual prying or simple mechanical ejection, which have several drawbacks: First, manual operation is inefficient, labor-intensive, and prone to product damage due to uneven force; second, mechanical ejection devices are often complex in structure and have poor positioning accuracy, easily causing deformation or surface scratches of the dust cover during demolding; third, while existing technologies use air-blowing demolding, the lack of effective sealing and fixing measures makes airflow prone to leakage, resulting in unsatisfactory demolding effects and even the safety hazard of the dust cover popping out and causing injury.

[0003] Therefore, there is an urgent need to develop a dust cover blowing demolding device that can achieve fast, safe, and non-destructive demolding in order to improve production efficiency, ensure product quality, and reduce operational risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust cover blowing and demolding device, which solves the problems mentioned above.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust cover blowing and demolding device, comprising a mold body connected to an air pump through an air inlet pipe, wherein the bottom of the mold body is provided with a conical surface that is inserted between the dust cover and the mold. The bottom of the mold body is fixedly connected to a ring arranged around the dust cover via a bracket. A connecting frame is fixedly connected to one side of the ring. A rotating rod is threadedly connected to the inner cavity of the connecting frame via a threaded groove. A pull rope is wound around the surface of the rotating rod. The inner cavity of the mold body is divided into an annular groove by an extrusion ring. One end of the pull rope passes through the mold body and wraps around the annular groove once. An extrusion block is fixedly connected to the bottom end of the rotating rod. The other end of the pull rope is fixedly connected to the bottom end of the extrusion block.

[0006] As a further aspect of this utility model, the distance between the collar and the surface of the mold body is 0.5cm.

[0007] As a further embodiment of this utility model: a switch valve connected to an air pump is fixed on the surface of the connecting frame.

[0008] As a further embodiment of this utility model: the inner cavity of the mold body is provided with a snap-fit ​​groove adapted to the mold surface, and the inner cavity of the snap-fit ​​groove is provided with an air guide groove. While being able to position, it can effectively guide the airflow to blow air between the dust cover and the mold, so that the dust cover can be detached from the mold. After the bottom of the mold body is inserted between the dust cover and the mold, the rotating rod is rotated to pull the pull rope to wrap around the rotating rod, which squeezes the extrusion ring and presses the dust cover and the collar together to prevent them from falling off. Then, air is blown.

[0009] Compared with the prior art, the present invention has the following advantages: 1. Achieves efficient and non-destructive demolding: The conical surface at the bottom of the mold body is precisely inserted into the gap between the dust cover and the mold. Combined with the airflow injected by the air pump through the air intake pipe, the dust cover can be separated from the mold evenly and smoothly, effectively avoiding product deformation or damage that may be caused by traditional mechanical demolding.

[0010] 2. A reliable fixing and sealing mechanism is provided: by the cooperation of the rotating rod and the threaded groove, the pull rope is driven to wind and tighten, thereby generating uniform radial pressure in the annular groove of the extrusion ring, realizing tight fixing and effective sealing between the mold body and the dust cover, preventing air leakage during demolding and ensuring the stability of the demolding effect.

[0011] 3. The structure is rationally designed, and operation is safe and convenient: the collar forms a stable support structure with the mold body through the connecting frame, and the design of the extrusion block enhances the fixing effect of the pull rope. The entire device has a compact structure, and the operation process is simple and reliable, effectively reducing the labor intensity and safety risks for operators. Attached Figure Description

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-2This utility model provides a technical solution: a dust cover blowing and demolding device, including a mold body 3 connected to an air pump through an air inlet pipe 6, and a conical surface at the bottom of the mold body 3 that is inserted between the dust cover 2 and the mold 1. A ring 4, which is annularly arranged around the dust cover 2, is fixedly connected to the bottom of the mold body 3 via a bracket. A connecting frame 5 is fixedly connected to one side of the ring 4. A rotating rod 10 is threadedly connected to the inner cavity of the connecting frame 5 via a threaded groove 12. A pull rope 8 is wound around the surface of the rotating rod 10. An annular groove 7 is separated from the inner cavity of the mold body 3 by an extrusion ring 9. One end of the pull rope 8 passes through the mold body 3 and wraps around the annular groove 7. An extrusion block 11 is fixedly connected to the bottom end of the rotating rod 10. The other end of the pull rope 8 is fixedly connected to the bottom end of the extrusion block 11.

[0016] The distance between the collar 4 and the surface of the mold 3 is 0.5cm.

[0017] A switch valve connected to the air pump is fixed to the surface of the connecting frame 5.

[0018] The inner cavity of the mold body 3 is provided with a snap-fit ​​groove that fits the mold surface, and the inner cavity of the snap-fit ​​groove is provided with an air guide groove. While being able to position, it can effectively guide the airflow to blow air between the dust cover 2 and the mold 1, so that the dust cover 2 is detached from the mold 1. After the bottom of the mold body 3 is inserted between the dust cover 2 and the mold 1, the rotating rod 10 is rotated to pull the rope 8 to wrap around the rotating rod 10, which squeezes the extrusion ring 9 and presses the dust cover 2 and the collar 4 together to prevent them from falling off. Then air is blown.

[0019] In use, the working principle of this invention is as follows: When it is necessary to detach the dust cover 2 from the mold 1, the conical surface at the bottom of the mold body 3 is first precisely inserted into the gap between the dust cover 2 and the mold 1. At this time, the snap-fit ​​groove in the inner cavity of the mold body 3 cooperates with the mold surface to achieve initial positioning, and the air guide groove provides a channel for subsequent airflow.

[0020] Next, the rotating rod 10 is rotated. Since the rotating rod 10 and the threaded groove 12 inside the connecting frame 5 form a threaded engagement, the rotating rod 10 undergoes axial displacement during rotation, causing the pull rope 8 wound around its surface to tighten continuously. One end of the pull rope 8 is fixed to the extrusion block 11, and the other end passes through the mold body 3 and wraps around the annular groove 7. As the pull rope 8 tightens, it generates a uniform extrusion force on the extrusion ring 9 in the annular groove 7, creating a tight press between the mold body 3, the dust cover 2, and the collar 4, preventing detachment during subsequent air blowing.

[0021] After the sealing is completed, the switch valve connected to the air pump is opened, and compressed air enters the mold body 3 through the air inlet pipe 6. The air is precisely guided by the air guide groove, and the airflow is concentrated and delivered to the joint between the dust cover 2 and the mold 1. Under the action of continuous airflow, the adsorption force between the dust cover 2 and the mold 1 is overcome, and the dust cover 2 is smoothly detached from the mold 1, completing the entire demolding process.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
