Description

Technical Field

[0001] This utility model relates to the field of liquid silicone molds, specifically a liquid silicone mold with an airflow-type auxiliary cleaning device. Background Technology

[0002] Liquid silicone molds (referred to as "liquid silicone molds or injection molds") are specialized molding tools used to process liquid silicone products. They are widely used in fields with high precision and high cleanliness requirements, such as medical, food, baby products, electronics, and automobiles. The core principle is to inject liquid silicone raw materials into the mold cavity, and after vulcanization, products with specific shapes, high elasticity, resistance to high and low temperatures, and biocompatibility are obtained.

[0003] In the existing technology, when using an airflow-assisted cleaning device to clean the molding cavity of a liquid silicone mold, there is a significant drawback: it can only clean the molding cavity in a single direction and cannot flexibly adjust the cleaning angle or direction, making it difficult to cover other surfaces of the molding cavity. Ultimately, this results in poor cleaning of the molding cavity of the liquid silicone mold, leading to incomplete and uneven cleaning. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figure 1 As shown, a liquid silicone mold with an airflow-assisted cleaning device includes a cleaning mold platform 1 and an airflow-assisted cleaning mechanism 5. Support components 3 for supporting the airflow-assisted cleaning mechanism 5 are provided on both sides of the upper end of the cleaning mold platform 1. A liquid silicone mold 2 is fixedly placed on the upper end of the cleaning mold platform 1 near the center. An angle adjustment component 4 for adjusting the angle of the airflow-assisted cleaning mechanism 5 is provided on the upper end of the support components 3 near the center.

[0018] In a specific embodiment, the cleaning mold platform 1 serves as the basic supporting structure, with the liquid silicone mold 2 fixedly placed at its center. The support components 3 on both sides provide vertical support for the airflow cleaning mechanism 5, positioning it above the liquid silicone mold 2 to form a covering cleaning area. The airflow cleaning mechanism 5 generates a high-speed airflow using compressed air, which is sprayed from the nozzle into the molding cavity of the liquid silicone mold 2. The high-speed airflow blows away residual silicone debris, dust, and other impurities on the surface of the molding cavity, achieving a cleaning effect. The airflow cleaning mechanism 5 is common in the prior art and will not be described in detail here.

[0019] Please refer to Figures 1 to 3 As shown, as a technical optimization of this utility model, the support component 3 includes two sets of base plates 31. The two sets of base plates 31 are respectively fixedly installed on the upper side of the cleaning mold table 1. Support guide rods 32 are fixedly connected to the top of the two sets of base plates 31 near both ends. The four support guide rods 32 form a rectangular frame structure. Connecting rods 33 are fixedly installed on the upper end of the four support guide rods 32. Fixing plates 34 are fixedly installed on the upper side of one side of two support guide rods 32.

[0020] In a specific embodiment, two sets of base plates 31 are fixed on both sides of the cleaning mold table 1. By increasing the contact area with the table surface, four support guide rods 32 form a rectangular frame. Utilizing the geometric stability of the rectangular structure, this frame structure can distribute the weight of the cleaning auxiliary device installed on the upper connecting rod 33, avoiding overload on a single guide rod.

[0021] Please refer to Figures 1 to 5 As shown, as a technical optimization of this utility model, the angle adjustment component 4 includes an inner disc 41. The upper end of the inner disc 41 is fixedly installed at the lower end of four connecting rods 33. A second annular sliding groove 412 is opened inside the outer wall of the inner disc 41. An inner annular sliding rod 413 is rotatably sleeved inside the second annular sliding groove 412. An annular tooth 43 is fixedly connected to the outer side of the inner annular sliding rod 413. An outer annular sliding rod 414 is fixedly connected to the outer side of the annular tooth 43. An outer disc 42 is rotatably sleeved on the outer side of the outer annular sliding rod 414. A first annular sliding groove 410 is opened inside the inner side of the outer disc 42, and the outer annular sliding rod 414 is rotatably sleeved inside the first annular sliding groove 410. Fasteners 48 are fixedly installed at equal intervals in annular shapes at the upper end of the outer disc 42. The lower ends of the three fasteners 48 are fixedly installed at the upper end of the inner disc 41. A fixing block 46 is fixedly connected to one side of the upper end of the inner disc 41. A bearing sleeve 49 is fixedly sleeved inside the fixing block 46.

[0022] Furthermore, a rotating shaft 45 is fitted inside the bearing sleeve 49. A bevel gear 44 is fixedly fitted on the outer side of the rotating shaft 45 near the fixed block 46. The outer side of the bevel gear 44 is meshed with the upper end of the ring gear 43. The outer side of the rotating shaft 45 away from the fixed block 46 is rotatably fitted inside the fixed plate 34. A fastening guide post 415 is fixedly connected to the lower end of the ring gear 43. A connecting plate 416 is fixedly installed on the lower end of the fastening guide post 415. An airflow cleaning mechanism 5 is fixedly installed on the lower end of the connecting plate 416. A servo motor 47 is fixedly installed on the outer side of the rotating shaft 45 away from the bevel gear 44. The output end of the servo motor 47 is connected to one end of the rotating shaft 45 for transmission. One end of the servo motor 47 is fixedly installed on one side of the fixed plate 34.

[0023] In a specific embodiment, the airflow cleaning mechanism 5 is adjusted to align with different positions of the liquid silicone mold 2 according to the cleaning requirements. The servo motor 47 is started, and the output torque drives the rotating shaft 45 to rotate. The rotating shaft 45 drives the bevel gear 44 at the end to rotate. The bevel gear 44 meshes with the tooth surface of the ring gear 43, converting the vertical rotational motion into the horizontal circular motion of the ring gear 43. The ring gear 43 rotates along the circular trajectory driven by the bevel gear 44. When the ring gear 43 rotates, the inner ring sliding rod 413 slides along the second ring sliding groove 412 of the inner disk 41, and the outer ring sliding rod 414 slides along the first ring sliding groove 410 of the outer disk 42. The double sliding constraint ensures that the ring gear 43 only performs pure circular motion, preventing deviation or shaking. The rotation of the ring gear 43 is transmitted to the airflow cleaning mechanism 5 through the fastening guide post 415 and the connecting plate 416, so that it rotates synchronously with the ring gear 43, realizing the angle adjustment from 0° to 360°. Thus, the airflow cleaning mechanism 5 can clean the upper surface or molding cavity of the liquid silicone mold 2 in different directions.

[0024] In use, this invention starts by controlling the servo motor 47, which outputs torque to drive the rotating shaft 45 to rotate. The rotating shaft 45 drives the bevel gear 44 at its end to rotate. The bevel gear 44 meshes with the tooth surface of the ring gear 43, converting the vertical rotational motion into the horizontal circular motion of the ring gear 43. The ring gear 43 rotates along a circular trajectory driven by the bevel gear 44. When the ring gear 43 rotates, the inner annular sliding rod 413 slides along the second annular sliding groove 412 of the inner disk 41, and the outer annular sliding rod 414 slides along the first annular sliding groove 410 of the outer disk 42. Double sliding constraints ensure that the ring tooth 43 only performs pure circular motion, preventing deviation or wobbling. The rotation of the ring tooth 43 is transmitted to the airflow cleaning mechanism 5 through the fastening guide post 415 and the connecting plate 416, causing it to rotate synchronously with the ring tooth 43, achieving angle adjustment from 0° to 360°. The support components 3 on both sides provide vertical support for the airflow cleaning mechanism 5, positioning it above the liquid silicone mold 2 to form a covering cleaning range. The airflow cleaning mechanism 5 generates a high-speed airflow using compressed air, which is sprayed from the nozzle into the molding cavity of the liquid silicone mold 2. The high-speed airflow blows away residual silicone debris, dust, and other impurities on the surface of the molding cavity.
