Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a base station front cover injection mold structure. Background Technology

[0002] A robotic vacuum cleaner, also known as an automatic sweeper or intelligent vacuum cleaner, is an intelligent cleaning device that integrates advanced sensor technology, intelligent algorithms, and a high-efficiency cleaning system. The base station of a robotic vacuum cleaner is an accessory device, primarily responsible for providing functions such as charging, cleaning, and maintenance for the robot. In the production of the base station casing, because the base station consists of multiple modules such as a robot mounting module, a water tank module, and a dust collection module, the different modules generally need to be manufactured independently during the base station casing production. These modules are then assembled using welding or snap-fit ​​methods. This design results in poor overall integrity of the assembled modules, making them prone to installation failures and leading to a low yield rate. Furthermore, the separate molding and assembly of each module results in low production efficiency for the robotic vacuum cleaner. Utility Model Content

The described embodiments are some, but not all, of the embodiments of this utility model.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see the appendix Figures 1-5This utility model provides a first embodiment of a base station front cover injection mold structure. This mold is used in the production of base station front covers for sweeping machines, enabling the base station front cover to be integrally molded, greatly improving the overall integrity of the base station front cover and significantly increasing the yield and production efficiency. Specifically, this mold structure includes an upper mold assembly 20 and a lower mold assembly 10.

[0040] The upper mold assembly 20 has an upper template 21, on which a first concave mold 211 is provided; the lower mold assembly 10 has a lower template 11, on which a first punch 111, a first side mold 112, and a second side mold 113 are provided. The first side mold 112 and the second side mold 113 are respectively provided on both sides of the first punch 111, and the first punch 111 is provided with at least one injection port. In this embodiment, the upper mold assembly 20 and the lower mold assembly 10 cooperate to close the mold, with the first concave mold 211 pressed onto the first punch 111, and the first punch 111, the first concave mold 211, the first side mold 112, and the second side mold 113 enclose and form an injection space.

[0041] The base station front cover injection mold structure of this utility model comprises an upper mold assembly 20 and a lower mold assembly 10. The upper mold plate 21 of the upper mold assembly 20 is provided with a first concave mold 211; the lower mold plate 11 of the lower mold assembly 10 is provided with a first convex mold 111, a first side mold 112, and a second side mold 113.

When the upper mold assembly 20 and the lower mold assembly 10 are closed, the first concave mold 211 is pressed onto the first convex mold 111, and the first convex mold 111, the first concave mold 211, the first side mold 112, and the second side mold 113 enclose and form an injection space. This mold structure forms the side plate of the base station front cover during injection molding by disposing the first side mold 112 and the second side mold 113 on both sides of the first convex mold 111 and the first concave mold 211. This solution enables the base station front cover to be injection molded as a single piece within the injection space, greatly improving its integrity, yield rate, and production efficiency.

[0042] Example 2:

[0043] Based on Embodiment 1, this utility model provides a second embodiment of a base station front cover injection mold structure. The mold structure specifically includes an upper mold assembly 20 and a lower mold assembly 10. This embodiment further describes the upper template 21 of the upper mold assembly 20 and the lower template 11 of the lower mold assembly 10.

[0044] In some implementations, the first punch 111 has a first sidewall and a second sidewall, which are respectively adjacent to the first sidewall 112 and the second sidewall 113, and are arc-shaped sidewalls. In this embodiment, the first and second sidewalls are arc-shaped sidewalls, and the side of the first sidewall 112 adjacent to the first sidewall and the side of the second sidewall 113 adjacent to the second sidewall are also arc-shaped, so that when the mold is closed, the first punch 111, the first sidewall 112, and the second sidewall 113 respectively form arc-shaped sidewalls. This utility model uses the arc-shaped sidewalls of the first sidewall 112, the second sidewall 113, and the first punch 111 to injection mold the arc-shaped sidewalls of the base station front cover.

[0045] In some implementations, the first die 211 is further provided with a first fitting groove 211g and a second fitting groove 211h. The first fitting groove 211g is fitted onto the first punch 111, and the two second fitting grooves 211h are respectively fitted onto the first side mold 112 and the second side mold 113. In this embodiment, the first fitting groove 211g and the second fitting groove 211h are carved into the side wall of the first groove, so that when the upper mold assembly 20 and the lower mold assembly 10 are closed, the first fitting groove 211g can be sealed and fitted with the upper end of the first punch 111; the second fitting groove 211h can be sealed and fitted with the upper ends of the first side mold 112 and the second side mold 113, thereby forming an injection space by the first punch 111, the first die 211, the first side mold 112 and the second side mold 113.

[0046] In some implementations, the first concave mold 211 is sequentially provided with a first upper groove 211a, a first upper protrusion 211b, and a second upper protrusion 211c; the first convex mold 111 is sequentially provided with a first lower protrusion 111a, a first lower groove 111b, and a second lower groove 111c; the first lower protrusion 111a is disposed opposite to the first upper groove 211a, and the first upper protrusion 211b and the second upper protrusion 211c are disposed opposite to the first lower groove 111b and the second lower groove 111c, respectively. In this embodiment, the first lower protrusion 111a disposed in the first upper groove can form a main cover space, the first upper protrusion 211b and the first lower groove enclose a dust box space, and the second upper protrusion 211c and the second lower groove enclose a robot mounting space. This allows each module of the sweeper to be integrally formed in this mold, avoiding the need for separate forming and assembly of each module, and further improving the production efficiency of the sweeper. In this design, after the front and rear covers of the base station are assembled, the space within the main cover can serve as a water supply and drainage area or a water tank area. In this solution, the main cover space, dustbin space, and robot installation space are sequentially connected to form the main body of the base station front cover.

[0047] In some implementations, the first lower protrusion 111a is provided with a first injection port 114, and the second lower groove 111c is provided with a second injection port 116. The first injection port 114 and the second injection port 116 are connected to the injection space. In this embodiment, since the base station front cover has a large volume, using a single injection port can easily cause uneven glue dispensing, making it difficult to form the base station front cover as a whole. This solution provides a first injection port 114 and a second injection port 116, which are connected to the injection space. The first injection port 114 and the second injection port 116 can be respectively located at both ends of the injection space, so that when the upper mold assembly 20 and the lower mold assembly 10 are closed, the first injection port 114 and the second injection port 116 can be used to uniformly inject glue into the injection space, thereby making the base station front cover more complete.

[0048] Furthermore, in the above embodiments, a first connecting groove 115 is provided between the first injection port 114 and the injection space, and a second connecting groove is provided between the second injection port 116 and the injection space. In this embodiment, the first connecting groove 115 and the second connecting groove can be used to store excess plastic material input into the injection space, so as to avoid overflow problems caused by too much plastic material and difficulty in molding caused by too little plastic material during injection molding.

[0049] In some implementations, the surface of the first lower protrusion 111a is provided with multiple transverse grooves 111e and multiple longitudinal grooves 111d. The transverse grooves 111e and longitudinal grooves 111d are interwoven and form a mesh structure on the surface of the first lower protrusion 111a. In this embodiment, the multiple transverse grooves 111e and multiple longitudinal grooves 111d are used to store plastic material, thereby forming reinforcing ribs inside the main cover space of the base station front cover, making the base station front cover structure more stable. At the same time, the interwoven transverse grooves 111e and longitudinal grooves 111d forming a mesh structure on the surface of the first lower protrusion 111a not only allows the plastic material to flow between the transverse grooves 111e and longitudinal grooves 111d, but also forms a mesh reinforcing rib inside the base station front cover, further improving the stability of the base station front cover structure.

[0050] In some implementations, the first lower groove 111b is provided with a first boss 111f, which is connected to the side wall of the first lower groove 111b, and a second boss 111j is provided on the first boss 111f; the first upper protrusion 211b is provided with a first forming groove 211d that matches the first boss 111f, and the first forming groove 211d has a second forming groove 211e that matches the second boss 111j; in this embodiment, the first lower groove 111b and the first upper protrusion 211b can form a dust box space; the first boss 111f, the second boss 111j, the first forming groove 211d and the second forming groove 211e form the dust box inlet of the base station front cover within the dust box space. The first boss 111f and the second boss 111j form a multi-layered stepped space inside the first lower groove 111b, which facilitates the installation of pipes and negative pressure modules.

[0051] The first lower groove 111b is also provided with a first mesh groove 111k, and the first upper protrusion 211b is provided with a first mesh hole that matches the first mesh groove 111k. The upper mold assembly 20 is provided with a first punch that can extend into the first mesh hole. When the upper mold assembly 20 and the lower mold assembly 10 are closed, the first punch passes through the first mesh hole and abuts against the first mesh groove 111k to form a mesh hole in the workpiece. In this embodiment, the first punch can pass through the first mesh hole and abut against the first mesh groove 111k to form a mesh hole in the workpiece. The mesh hole can be used to communicate with the outside air to stabilize the airflow in the front cover of the base station. When the upper mold assembly 20 and the lower mold assembly 10 are closed, injection molding is performed into the injection space through the injection port. After the injection space is filled with plastic material, the first punch passes through the first mesh hole and abuts against the first mesh groove 111k to form a mesh hole in the workpiece.

[0052] In some implementations, the second lower groove 111c is an arc-shaped groove, and the second upper protrusion 211c is provided with an arc-shaped protrusion and a partition protrusion. The arc-shaped protrusion matches the second lower groove 111c, and the partition protrusion is sealed to the lower template 11. In this embodiment, the second upper protrusion 211c and the second lower groove enclose a robot mounting space. The second lower groove 111c is an arc-shaped groove, and the arc-shaped protrusion can be used for the arc-shaped robot mounting and placement. The partition protrusion can be used to seal and enclose the first punch 111, the first die 211, the first side mold 112, and the second side mold 113 to form an injection molding space. An arc-shaped groove is provided between the partition protrusion and the arc-shaped protrusion to form the arc-shaped sidewall of the robot mounting space.

[0054] Based on Embodiment 1 or Embodiment 2, this utility model provides a third embodiment of a base station front cover injection mold structure, which specifically includes an upper mold assembly 20 and a lower mold assembly 10. This embodiment further supplements the upper mold assembly 20 and the lower mold assembly 10.

[0055] The upper mold assembly 20 includes an upper mold fixing plate 22 and an upper mold pad 23. The upper mold plate 21 is fixed to the upper mold fixing plate 22 via the upper mold pad 23. The lower mold assembly 10 includes a lower mold fixing plate 12, a lifting plate 14, and a pad 13. The lifting plate 14 and the pad 13 are disposed on the lower mold fixing plate 12. The lower mold plate 11 is disposed on the upper end of the pad 13. The upper end of the lifting plate 14 is provided with multiple ejector pins, which are inserted into pin holes in the lower mold plate 11. After the upper mold assembly 20 and the lower mold assembly 10 are closed, the base station front cover is injection molded in the injection space. After injection molding is completed, the lifting plate 14 rises under the action of an external driving component, thereby causing the base station front cover to be ejected by the ejector pins, completing the demolding process.

[0056] In addition, the upper mold assembly 20 is provided with guide pillars, and the lower mold assembly 10 is provided with guide holes corresponding to the first guide pillars. The guide pillars extend into the guide holes, and the stability of the mold movement during mold opening and closing can be improved through the first guide pillars and the first guide holes.

[0057] The utility model provides a base station front cover injection mold structure, which includes an upper mold assembly 20 and a lower mold assembly 10. The upper mold plate 21 of the upper mold assembly 20 is provided with a first concave mold 211; the lower mold plate 11 of the lower mold assembly 10 is provided with a first convex mold 111, a first side mold 112, and a second side mold 113. The first side mold 112 and the second side mold 113 are respectively disposed on both sides of the first convex mold 111, and the first convex mold 111 is provided with at least one injection port. When the upper mold assembly 20 and the lower mold assembly 10 are closed, the first concave mold 211 is pressed onto the first convex mold 111, and the first convex mold 111, the first concave mold 211, the first side mold 112, and the second side mold 113 enclose and form an injection space. This mold structure forms the side plate of the base station front cover during injection molding by disposing the first side mold 112 and the second side mold 113 on both sides of the first convex mold 111 and the first concave mold 211. This solution enables the base station front cover to be injection molded as a single piece within the injection space, greatly improving its integrity, yield rate, and production efficiency.
