Description

Technical Field

[0001] This application belongs to the field of bearing miniature spacer cages, and particularly relates to a miniature spacer production cavity collection device. Background Technology

[0002] Currently, most miniature spacer cages used in bearings are made of engineering plastics. Engineering plastics possess numerous excellent properties, making them ideal materials for manufacturing miniature spacer cages. In terms of manufacturing processes, injection molding is widely used due to its high efficiency, precision, and ability to support large-scale production. The basic principle of injection molding is to heat the engineering plastic material to a molten state, then inject it into a mold cavity under high pressure. After cooling and solidification, the desired shape and size of the miniature spacer cage product is obtained. In actual production, to improve production efficiency and reduce costs, multi-cavity molds are typically used for injection molding of miniature spacer cages. For example, a mold may have 20 cavities, producing 20 miniature spacer cage products simultaneously in one injection cycle. However, due to limitations in mold manufacturing precision and slight differences in material properties, there are certain differences between the miniature spacer cage products produced in different cavities and the standard dimensions, and there are also differences in the product dimensions between different cavities. However, these differences are within reasonable tolerances, ensuring the basic quality of the product to a certain extent.

[0003] In bearing assembly, multiple miniature spacer blocks are typically installed within a single bearing. These spacer blocks must be matched to each other and cannot be arbitrarily combined. If the assembled spacer blocks are all too large (a little larger than the standard size), the gaps between them will be too small after bearing assembly. This will increase the friction between the spacer blocks and the rolling elements during bearing operation, generating excessive heat and affecting the normal operation of the machinery. Conversely, if the assembled spacer blocks are all too small (a little smaller than the standard size), the gaps between them will be too large. This will cause significant runout and vibration of the rolling elements during operation, leading to unstable bearing operation. Currently, in the production process of miniature spacer block cages, products from each cavity are typically collected and placed in a collection box. While this collection method is simple and convenient, it cannot effectively distinguish products from different cavities. Due to the differences in product dimensions between different cavities, it is difficult to rationally match and assemble them according to size requirements after collection, failing to meet the strict requirements for spacer block size matching in bearing assembly. This not only affects the assembly quality and production efficiency of the bearing but may also lead to the waste of some products due to unmet assembly requirements, increasing production costs. This shows that existing technologies need further improvement and enhancement. Utility Model Content

[0004] This utility model provides a micro-isolation block production cavity collection device to solve the problem that after the micro-isolation blocks are collected in a centralized manner, it is difficult to reasonably match and assemble them according to size requirements. This cannot meet the strict requirements of bearing assembly for the size matching of isolation blocks, which not only affects the bearing assembly quality and production efficiency, but may also lead to some products being wasted because they cannot meet the assembly requirements, thus increasing production costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A micro-isolation block production cavitation collection device includes:

[0007] The air collection tube mechanism is equipped with multiple air collection tubes, the same number as the number of cavities in the injection mold. One end of each air collection tube is the opening end of the corresponding cavity of the injection mold to receive the micro-isolation block molded products, and the other end is connected to the collection terminal for collecting the products separately.

[0008] The lifting mechanism, connected to multiple air collection pipes, can drive the air collection pipes down to align the opening end with the cavity after the rear mold and front mold of the injection molding machine separate. After collection is completed, it drives the air collection pipes up to reset.

[0009] The suction mechanism is configured to be connected to the collection terminal. When the ejection mechanism ejects the micro-isolation block molded product to the opening end of the collection pipe, it generates a suction force to draw the product along the collection pipe to the collection terminal.

[0010] The aforementioned structure allows the lifting mechanism to precisely control the position of the collecting air pipes. After the mold separates, it quickly lowers the collecting air pipes, ensuring that the opening of each collecting air pipe accurately aligns with its corresponding cavity. This guarantees that the micro-isolation blocks produced in each cavity can be accurately received, achieving rapid and precise cavity-specific collection. The suction force generated by the air extraction mechanism promptly draws the products ejected to the opening of the collecting air pipes along the pipes to the collection terminal. The entire collection process is rapid and smooth, significantly shortening collection time and improving production efficiency. Compared to traditional centralized collection methods, cavity-specific collection avoids the chaotic accumulation of products in the collection box, reducing subsequent sorting time and effort. Since products from different cavities are collected separately to the collection terminal through their respective collecting air pipes, the products in each collection terminal originate from the same cavity and have similar dimensional characteristics. This allows subsequent measurements to be performed individually for products from each cavity, eliminating the need to sift through a large number of mixed products, thus improving the targeting and accuracy of measurements.

[0011] In a preferred embodiment, a fixed limiting plate is provided at the middle position of the air collection tube, and a lifting limiting plate is provided at the open end. Both the fixed limiting plate and the lifting limiting plate are provided with tube holes adapted to the number of air collection tubes, and the positions of the tube holes correspond to the positions of the cavity. The fixed limiting plate is located above the injection mold, and the lifting limiting plate is connected to the lifting mechanism. The air collection tubes pass through the tube holes of the fixed limiting plate and the lifting limiting plate.

[0012] When the lifting mechanism is running, the lifting limit plate drives the collecting air pipe to move synchronously. Simultaneously, a fixed limit plate, located in the middle of the collecting air pipe and fixed above the injection mold (e.g., on a hanger), also has a corresponding hole for the collecting air pipe, which passes through this hole. The fixed limit plate stabilizes the middle position of the collecting air pipe, ensuring relative stability during lifting and lowering.

[0013] In a preferred implementation, the air collection tube is divided into a flexible tube on one side and a rigid tube on the other side by a lifting limiting plate, with the open end located on the rigid tube.

[0014] Rigid tubes possess shape stability, and their rigidity ensures that the open end is not easily deformed during long-term use, maintaining a precise correspondence with the cavity and thus ensuring accurate collection every time. Flexible tubes, on the other hand, have good flexibility and bendability. During operation, the lifting mechanism drives the collection tube to move up and down, and the presence of flexible tubes allows the collection tube to adapt more flexibly to the movement trajectory during lifting and lowering.

[0015] In a preferred implementation, the diameter of the collecting tube is larger than that of the cavity to facilitate smooth movement of the product.

[0016] In a preferred implementation, the collection terminal is a collection bottle, the body of which has a connection port, and one end of the collection tube is detachably connected to the connection port.

[0017] In a preferred implementation, the mouths of multiple collection bottles are detachably connected to a suction pipe, which is connected to a suction mechanism.

[0018] In a preferred embodiment, the suction pipe is provided with a connecting sleeve, the connecting sleeve is hollow and connects to the internal space of the suction pipe, the connecting sleeve is provided with an internal thread, and the bottle mouth of the collection bottle is provided with an external thread, and the two are threadedly connected.

[0019] In a preferred implementation, the lifting mechanism is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0020] In a preferred implementation, the air extraction mechanism is an air pump. Attached Figure Description

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] The present invention will now be described with reference to the accompanying drawings.

[0032] The specific solution adopted is as follows:

[0033] like Figure 1-3 As shown, this utility model provides a micro-isolation block production cavity collection device, comprising:

[0034] The air collection tube 1 mechanism is equipped with multiple air collection tubes 1, the same number as the number of cavities 40 of the injection mold 4. One end of each air collection tube 1 is an opening end 10 corresponding to each cavity 40 of the injection mold 4 to receive the micro-isolation block molded products, and the other end is connected to a collection terminal for collecting the products separately.

[0035] The lifting mechanism 2 is connected to multiple air collection pipes 1. After the rear mold 4 and the front mold 4 of the injection molding machine are separated, it can drive the air collection pipes 1 to descend so that the opening end 10 corresponds to the cavity 40. After the collection is completed, it can drive the air collection pipes 1 to rise and reset.

[0036] The suction mechanism is configured to be connected to the collection terminal. When the ejection mechanism ejects the micro-isolation block molded product to the opening end 10 of the collection pipe 1, it generates a suction force to draw the product along the collection pipe 1 to the collection terminal.

[0037] By employing the micro-isolator block production cavity collection device of this application, the lifting mechanism 2 can precisely control the position of the collection air pipe 1. After the mold 4 separates, it quickly drives the collection air pipe 1 to descend, ensuring that the opening end 10 of each collection air pipe 1 accurately corresponds to the corresponding cavity 40. This ensures that the micro-isolators produced in each cavity 40 can be accurately received, achieving rapid and precise cavity collection. The suction force generated by the suction mechanism can promptly extract the products ejected to the opening end 10 of the collection air pipe 1 along the pipe to the collection terminal. The entire collection process is rapid and smooth, greatly shortening the collection time and improving production efficiency. Compared with the traditional centralized collection method, cavity collection avoids the chaotic accumulation of products in the collection box, reducing the time and effort required for subsequent sorting. Since products from different cavities 40 are collected separately to the collection terminal through their respective collection air pipes 1, the products in each collection terminal come from the same cavity 40 and have similar dimensional characteristics. This allows subsequent measurement work to be performed individually for the products in each cavity 40, eliminating the need to screen from a large number of mixed products, thus improving the targeting and accuracy of the measurement.

[0038] During bearing assembly, it is necessary to match the spacers according to their dimensions. The cavity collection device collects products with different cavities 40 separately, so that during assembly, spacers with matching dimensions can be selected based on the size characteristics of each cavity 40 product. This effectively avoids assembly problems caused by size mismatch, such as spacer gaps that are too large or too small, and improves the bearing assembly quality.

[0039] See Figure 1 and Figure 2 A fixed limiting plate 20 is provided at the middle of the air collection pipe 1, and a lifting limiting plate 21 is provided at the open end 10. The lifting mechanism 2 is mainly connected to the lifting limiting plate 21, thereby driving the air collection pipe 1 to move up and down. The lifting limiting plate 21 is a key supporting component for the function of the lifting mechanism 2. It has pipe holes adapted to the number of air collection pipes 1, and the positions of the pipe holes correspond one-to-one with the positions of the cavity 40 of the injection mold 4. The air collection pipe 1 passes through the pipe holes of the lifting limiting plate 21. When the lifting mechanism 2 is running, it can drive the air collection pipe 1 to move synchronously through the lifting limiting plate 21. At the same time, the fixed limiting plate 20 provided at the middle of the air collection pipe 1 is fixed above the injection mold 4, such as on a hanger. It also has pipe holes corresponding to the air collection pipe 1, and the air collection pipe 1 also passes through the pipe holes of the fixed limiting plate 20. The fixed limiting plate 20 serves to stabilize the middle position of the collecting air tube 1, ensuring that the collecting air tube 1 remains relatively stable during the lifting process, and that the hose does not droop excessively, shake or deviate. The lifting mechanism 2 focuses on driving the opening end 10 of the collecting air tube 1 to move up and down precisely.

[0040] Furthermore, the collecting air tube 1 is divided into a flexible tube on one side and a rigid tube on the other side, with the opening end 10 located on the rigid tube, using the lifting limit plate 21 as the boundary. The rigid tube has the characteristic of shape stability, and its rigidity ensures that the opening end 10 is not easily deformed during long-term use, always maintaining a precise correspondence with the cavity 40, thus ensuring accurate collection every time. The flexible tube, on the other hand, has good flexibility and bendability. When the lifting mechanism 2 is working, it drives the collecting air tube 1 to move up and down. The presence of the flexible tube allows the collecting air tube 1 to adapt to the movement trajectory more flexibly during lifting and lowering, reducing jamming or resistance caused by excessive rigidity. The flexible tube and the rigid tube can be combined using various existing connection methods, such as compression fitting and heat fusion connection, which will not be elaborated here.

[0041] Furthermore, the diameter of the collecting tube 1 is larger than that of the cavity 40 to facilitate smooth movement of the product.

[0042] As a preferred embodiment of this application, see [link to application]. Figure 3 The collection terminal is a collection bottle 3, and the body of the collection bottle 3 is equipped with a connection port 30. One end of the collection air pipe 1 is detachably connected to the connection port 30. The detachable connection design allows the operator to quickly remove the collection bottle 3 from the collection air pipe 1 when it is full and replace it with an empty collection bottle 3, thereby ensuring the continuity of the production process, avoiding production interruption due to the collection device being full, and improving overall production efficiency.

[0043] In a preferred embodiment of this application, the mouths of the plurality of collection bottles 3 are detachably connected to the suction pipe 31, and the suction pipe 31 is connected to the suction mechanism.

[0044] Once the suction mechanism is activated, the micro-isolating blocks are drawn into the collection bottle 3 along the collection pipe 1 under the suction force, thus achieving efficient collection. One suction pipe 31 connects to multiple collection bottles 3 simultaneously, allowing multiple collection bottles 3 to collect the micro-isolating blocks in parallel. This eliminates the need for a separate suction device for each collection bottle 3, further reducing the overall cost of the equipment.

[0045] See Figure 2 The suction pipe 31 is provided with a connecting sleeve 310. The connecting sleeve 310 is hollow and connects to the internal space of the suction pipe 31. The connecting sleeve 310 is provided with an internal thread, and the bottle mouth of the collection bottle 3 is provided with an external thread. The two are connected by threads to achieve disassembly and assembly.

[0046] As a preferred embodiment of this application, the lifting mechanism is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0047] In a preferred embodiment of this application, the air extraction mechanism is an air extraction pump, which is connected to an air extraction pipe.

[0048] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0049] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
