Description

Technical Field

[0001] This utility model relates to the field of injection molding, and more particularly to embedded injection molding equipment. Background Technology

[0002] In traditional injection molding, if a product structure requires the embedding of metal parts to enhance its mechanical strength, conductivity, or other specific functions, this process is often highly dependent on manual operation. Specifically, operators must first precisely place the metal parts into the designated positions in the mold to ensure that the metal parts are completely encased in plastic and accurately positioned during subsequent injection molding. After completing the injection molding step, the molded plastic part containing the metal parts must be manually removed from the mold to prepare for the next round of metal part placement and injection. This series of operations relies heavily on manual labor, resulting in low production efficiency.

[0003] Furthermore, manual operation always introduces certain manufacturing errors, resulting in poor consistency in the produced pet scissors. At the same time, frequent human intervention makes it difficult to control the consistency and stability of the production line, easily leading to defective products and a high scrap rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an embedded injection molding device that can solve the problems of low processing efficiency, poor product consistency and high scrap rate.

[0008] Preferably, the embedded injection molding equipment further includes a separation device, which includes a separation drive mechanism and a separation pick-and-place mechanism. The separation drive mechanism is used to drive the separation pick-and-place mechanism to move, so that the separation pick-and-place mechanism can clean up excess material on the injection molding equipment.

[0009] Preferably, the separation drive mechanism includes a separation rotary drive component, a separation rotary frame, a separation lifting drive component, a separation lifting seat, and a separation sliding drive component;

[0011] Preferably, the storage mechanism includes a divider, a dividing drive, and at least one dividing fixture;

[0012] The dividing drive is driven and connected to the divider, and each of the dividing fixtures is disposed on the divider, with each dividing fixture corresponding to and defining each of the storage positions on the divider.

[0013] The dividing drive drives the divider to rotate, thereby aligning at least one of the storage positions with the feeding mechanism; the feeding mechanism is used to push the metal parts in the storage positions to a position where the picking mechanism can pick up the materials.

[0014] Preferably, in one of the dividing fixtures, the dividing fixture includes a plurality of limiting posts, each of the limiting posts being disposed on the divider, thereby defining the storage position on the divider by each limiting post.

[0015] Preferably, each of the limiting posts has a limiting groove, and each limiting groove is adapted to the outer contour of the metal part.

[0016] Preferably, the material handling drive mechanism includes a multi-axis robotic arm, and the material handling mechanism includes a material handling frame and at least one material handling component;

[0017] The multi-axis robotic arm is driven and connected to the material handling rack. Each material handling component is disposed on the material handling rack. The multi-axis robotic arm is used to drive the material handling rack to move, so that the material handling component can not only pick up the metal parts in the storage position, but also place the metal parts in the injection molding device, and can remove the material from the injection molding device.

[0018] Preferably, the material handling rack is provided with a first installation area and a second installation area, and the material handling component is provided in each of the first installation area and the second installation area;

[0019] Each of the aforementioned material handling components includes several vacuum suction cups, and each of the aforementioned vacuum suction cups is disposed on the material handling rack.

[0020] Preferably, the material handling device further includes a positioning mechanism, which includes a plurality of positioning fixtures, each of which has a positioning groove adapted to the metal part;

[0021] The positioning groove is used to position the inserted metal part, thereby limiting the relative position of the metal part and the picking rack when the picking device removes the metal part.

[0022] The second aspect of this utility model also provides a pet scissors, the pet scissors including the metal part described in any of the above technical solutions, the metal part being injection molded with plastic on the injection molding device.

[0023] The following are the beneficial effects of implementing this utility model:

[0024] This utility model relates to an embedded injection molding device, in which pet scissors are manufactured by processing metal parts on the embedded injection molding device. On the embedded injection molding device, a feeding device automatically pushes the metal parts, and a picking device allows the metal parts to be automatically, quickly, and accurately placed into the injection molding device for injection molding. This allows the plastic material to be automatically injected into the predetermined position on the metal parts, thereby forming the required material, i.e., forming the pet scissors. After injection molding, the picking device removes the material from the injection molding device and places the metal parts to be processed back into the injection molding device.

[0025] This greatly eliminates the tedious manual handling of metal parts and pet scissors, effectively improving production efficiency. It also eliminates errors caused by manual operation, improves the consistency of product production, and increases the yield rate of products. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Figure 1 An embedded injection molding device 10 is shown in some embodiments of the present invention, which is used for injection molding.

[0043] like Figure 1 and Figure 2 As shown, the embedded injection molding equipment 10 includes an injection molding device 1, a feeding device 2, and a material handling device 3 for injection molding.

[0044] Understandably, the injection molding device 1 is used to perform injection molding on the parts placed inside it. During the injection molding process, the rubber material will gather at a predetermined position on the parts. After the rubber material cools down, the required material is produced by injection molding (the material referred to here varies depending on different production and processing needs. It can refer to the product obtained after further injection molding of metal parts or the product obtained after further processing of non-metal parts).

[0045] like Figure 3 As shown, the feeding device 2 includes a storage mechanism 21 and a feeding mechanism 22. The storage mechanism 21 is provided with a storage position 214 for accommodating the metal part 20, and the feeding mechanism 22 is used to push the metal part 20 into the storage position 214.

[0046] Understandably, the storage mechanism 21 is used to store materials to be injection molded, such as metal parts. The feeding mechanism 22 is used to push the metal parts 20 in the storage position 214, so that the metal parts 20 can be pushed to the corresponding position where the material picking device 3 can pick them up. This position varies depending on the actual processing design of the equipment. A single storage position 214 can accommodate multiple metal parts 20, thereby eliminating the tedious task of repeatedly loading materials into the storage mechanism 21.

[0047] It should be noted that the shape of the metal part 20 can be flexibly set; correspondingly, the outline of the storage position 214 can also be set according to the shape of the metal part 20 to accurately position the function of the metal part 20.

[0048] like Figure 2 and Figure 3 As shown, the material handling device 3 includes a material handling drive mechanism 31 and a material handling mechanism 32. The material handling drive mechanism 31 is used to drive the material handling mechanism 32 to move, so that the material handling mechanism 32 can not only load the metal part 20 on the storage position 214 onto the injection molding device 1, but also unload the material on the injection molding device 1.

[0049] Understandably, the material handling drive mechanism 31 is used to drive the material handling mechanism 32 to move along a predetermined path. The material handling mechanism 32 is used to pick up and place materials (materials include un-injection molded metal parts and metal parts that have been metal-processed).

[0050] It should be noted that the positions of each device can be flexibly set. When the relative positions between devices change, the moving path of the material picking mechanism 31 driving the material picking mechanism 32 will also be different, so that the material picking mechanism 32 can move smoothly to the predetermined position to complete the picking and placing of materials.

[0051] In addition to the above, it should also be noted that the storage mechanism 21 can stack and store the metal parts 20 in an orderly manner. After being stacked and stored, the metal parts 20 are pushed in an orderly manner by the feeding mechanism 22. The metal parts pushed to the predetermined position can be picked up by the picking device 3.

[0052] In actual operation, the material picking drive mechanism 31 drives the material picking mechanism 32 to move to the storage position 214. Then the material picking mechanism 32 picks up the metal part 20. The metal part 20 is fixed by the material picking mechanism 32. In the subsequent movement, the metal part 20 will move together with the material picking mechanism 32.

[0053] The material handling drive mechanism 31 drives the material handling mechanism 32 to move onto the injection molding device 1, placing the metal part 20 inside the injection molding device 1. Subsequently, the injection molding device 1 closes the mold and performs injection molding. The plastic material is injected and comes into contact with the predetermined part on the metal part 20. After the plastic material cools, the required plastic is formed at the predetermined position on the metal part 20. The shape of the formed plastic can be flexibly set. The specific setting can be achieved by modifying or replacing the injection mold on the injection molding device 1, thereby changing the injection cavity. The change of the injection cavity can correspondingly change the surface contour and size of the formed plastic.

[0054] It should also be noted that when the material handling mechanism 32 places the metal part 20 between the injection molding units 1, the material handling mechanism 32 can be configured to first remove the material that has already undergone injection molding from the injection molding unit 1, and then place the un-injected metal part into the injection molding unit 1. Furthermore, the material handling mechanism 32 can be configured to have at least two material handling positions, so that the un-processed metal part can be handled through one position, and the material that has already undergone injection molding can be handled through the other position.

[0055] In the above processes, not only is the tedious manual handling of metal parts 20 eliminated, but also the manual handling of injection molding materials is eliminated. This improves the accuracy of metal part handling, thereby enhancing product processing consistency and ensuring high production yield. Furthermore, the feeding device 2 and the unloading device 3 fully utilize the time available at each stage of the processing, improving production efficiency.

[0056] like Figure 2 As shown, in some embodiments of the embedded injection molding equipment 10, the embedded injection molding equipment 10 further includes a separation device 4, which includes a separation drive mechanism 41 and a separation pick-and-place mechanism 42. The separation drive mechanism 41 is used to drive the separation pick-and-place mechanism 42 to move, so that the separation pick-and-place mechanism 42 can clean up excess material on the injection molding equipment 1.

[0057] Understandably, the separation drive mechanism 41 is used to drive the separation pick-and-place mechanism 42 to move towards or away from the injection molding device 1, so that the separation pick-and-place mechanism 42 can smoothly complete the pick-and-place operation at a predetermined position. The separation drive mechanism 41 can be configured as a servo motor or a pneumatic / hydraulic drive system. The separation pick-and-place mechanism 42 can be customized according to the specific shape of the material after injection molding and the structural characteristics of the injection mold. The separation pick-and-place mechanism 42 can be configured as a gripper or a suction cup, which can accurately position and firmly grasp excess material remaining on or inside the injection mold surface, such as overflow, burrs, or other unwanted parts.

[0058] It should be noted that the sprue after injection molding can be clamped by the separation and pick-up mechanism 42, and then driven to move by the separation drive mechanism 41 to complete the removal of the injection molding sprue, which further eliminates the tediousness of manual operation and improves the production and processing efficiency of the product.

[0059] like Figure 4 As shown, in some embodiments of the embedded injection molding equipment 10, the separation drive mechanism 41 includes a separation rotary drive 411, a separation rotary frame 412, a separation lifting drive 413, a separation lifting seat 414, and a separation sliding drive 415.

[0060] The separation rotary drive 411 is used to drive the separation rotary frame 412 to rotate, the separation lifting drive 413 is used to drive the separation lifting seat 414 to move up and down on the separation rotary frame 412, and the separation sliding drive 415 is used to drive the separation pick-and-place mechanism 42 to move telescopically on the separation lifting seat 414 so that the separation pick-and-place mechanism 42 enters the injection molding device 1 to pick up materials.

[0061] Understandably, the separation rotary drive 411 can be configured as a power element such as an electric motor, cylinder, or hydraulic motor to drive the separation rotary frame 412 to rotate around a central axis. This allows the separation pick-and-place mechanism 42 to be oriented in the horizontal direction. The separation rotary frame 412 is used to mount and fix the remaining components and to provide support for the movement of the corresponding components, allowing the remaining components to slide or rotate after the horizontal orientation is adjusted. The separation lifting drive 413 is used to drive the separation pick-and-place mechanism 42 to move up and down relative to the separation rotary frame 412. The separation lifting seat 414 is driven by the separation lifting drive 413 to drive the separation pick-and-place mechanism 42 to move up and down. The separation sliding drive 415 is used to push the separation pick-and-place mechanism 42 to move telescopically on the separation lifting seat 414, further refining the precision of the operation. In this way, the separation pick-and-place mechanism 42 can penetrate deep into the injection mold of the injection molding device 1 and accurately contact the excess material that needs to be cleaned (such as sprue and other injection molding scraps).

[0062] like Figure 3 As shown, in some embodiments of the embedded injection molding equipment 10, the material storage mechanism 21 includes a divider 211, a dividing drive 212, and at least one dividing fixture 213; the dividing drive 212 is driven to the divider 211, and each dividing fixture 213 is disposed on the divider 211, and each dividing fixture 213 defines a corresponding material storage position 214 on the divider 211.

[0063] The dividing drive 212 drives the divider 211 to rotate, thereby aligning at least one storage position 214 with the feeding mechanism 22; the feeding mechanism 22 is used to push the metal part 20 in the storage position 214 to a position where the picking mechanism 32 can pick up the material.

[0064] Understandably, the divider 211 serves to support the various dividing fixtures 213 and the metal parts 20. The dividing drive 212 is connected to the divider 211 and drives its rotation. Thus, the divider 211 can precisely align one or more storage positions 214 with the feeding mechanism 22 according to the needs of the production process. This means that the equipment can flexibly select and release the metal parts 20 in specific storage positions 214 according to changes in processing sequence or material requirements, significantly improving the flexibility and efficiency of the feeding process.

[0065] The number of dividing jigs 213 can be configured to be one or more, each of which can independently accommodate and limit the metal parts 20, thereby ensuring that the metal parts 20 in different storage positions 214 maintain a predetermined arrangement and position during storage and transfer. This prevents the metal parts 20 from being mispositioned during the rotation of the divider 211, which would affect material retrieval and ensures accurate subsequent material retrieval. The feeding mechanism 22 can be configured to push the arranged metal parts 20 out of the storage position 214 by lifting, holding, or pushing, and deliver them to a position easily accessible by the retrieving mechanism 32. This process is automated and precise, reducing manual intervention and improving overall production efficiency and product quality.

[0066] It should be noted that a position sensor or position detector can be configured to monitor the current position of the metal part. When the sensor detects that the metal part 20 has moved to the predetermined position, the feeding mechanism 22 stops pushing, ensuring that the metal part 20 accurately stops at the predetermined pick-up position. This guarantees pick-up accuracy and improves the precision of injection molding.

[0067] like Figure 3 As shown, in some embodiments of the embedded injection molding equipment 10, in a dividing fixture 213, the dividing fixture 213 includes a plurality of limiting posts 2131, each limiting post 2131 is disposed on the divider 211, so that each limiting post 2131 defines a material storage position 214 on the divider 211.

[0068] Understandably, the plurality of limiting posts 2131 provided on each dividing fixture 213 are configured according to the specific size and shape of the metal part 20. On the one hand, each limiting post 2131 serves as a physical boundary to ensure that the metal part remains in a fixed position in the storage position 214, preventing rolling, tilting or collision during storage or position change; on the other hand, when each metal part 20 is held and moved by the feeding mechanism 22, the setting of the limiting posts 2131 ensures that each metal part 20 can be kept in the predetermined position as much as possible, ensuring that the picking device 3 can smoothly and accurately pick up the metal part 20.

[0069] like Figure 3As shown, in some embodiments of the embedded injection molding equipment 10, each limiting post 2131 has a limiting groove 2132, and each limiting groove 2132 is adapted to the outer contour of the metal part 20.

[0070] Understandably, the shape, size, and layout of the limiting grooves 2132 on each limiting post 2131 are customized according to the outer contour of the metal part 20. This means that the limiting grooves 2132 can fit tightly against the edge or specific structure of the metal part 20, not only providing physical constraints to prevent unnecessary movement of the metal part during storage and feeding, but also further ensuring the positional stability of the metal part during storage and processing by precisely matching its contour.

[0071] like Figure 5 As shown, in some embodiments of the embedded injection molding equipment 10, the material handling drive mechanism 31 includes a multi-axis robotic arm 311, and the material handling mechanism 32 includes a material handling rack 321 and at least one material handling component 322.

[0072] The multi-axis robotic arm 311 is driven and connected to the material handling rack 321. Each material handling component 322 is set on the material handling rack 321. The multi-axis robotic arm 311 is used to drive the material handling rack 321 to move, so that the material handling component 322 can not only pick up the metal part 20 in the material storage position 214, but also place the metal part 20 into the injection molding device 1, and can also take out the material on the injection molding device 1.

[0073] Understandably, the multi-axis robotic arm 311 can be precisely controlled along multiple degrees of freedom (such as linear movement along the X, Y, and Z axes and rotation around these axes), thus adapting to various complex working environments and operational requirements. Through its connection with the material handling rack 321, the multi-axis robotic arm 311 can drive the material handling rack 312 to move precisely in space, ensuring that the material handling assembly 322 can accurately reach all necessary working positions, such as the storage position 214 and the injection molding device 1.

[0074] The material handling rack 321, through its drive connection with the multi-axis robotic arm 311, enables the material handling components 322 to move together. Furthermore, the number of material handling components 322 and their positions on the material handling rack 321 can be adjusted according to different processing requirements, enhancing the system's adaptability and flexibility.

[0075] The material handling assembly 322 is used to directly perform material handling and placement operations. The material handling assembly 322 can be configured as a gripper, suction cup, or a dedicated grasping tool, and can be set according to the specific shape and material of the metal part 20 to ensure the stability and safety of the handling and placement process. By setting multiple material handling assemblies, the equipment can process multiple metal parts simultaneously or complete the task of handling and placing different types of materials, further improving production efficiency.

[0076] like Figure 5 As shown, the multi-axis robotic arm 311 includes multiple movable parts 3111, which are connected in sequence. The movable part 3111 located at the end is provided with an output shaft 3112, which drives the material handling mechanism 32.

[0077] Understandably, the various moving parts 3111 can be rotatably connected by power components such as motors, and the output shaft 3112 can be configured to be driven by a motor or cylinder, so that the output shaft 3112 can drive the material handling mechanism 32 to rotate.

[0078] It should be noted that, in actual use, the movement of multiple moving parts 3111 can drive the material handling mechanism 32 set on the output shaft 3112 to move, so that the material handling mechanism 32 can smoothly complete the material handling of metal parts and injection molded finished products.

[0079] like Figure 5 As shown, in some embodiments of the embedded injection molding equipment 10, the material picker 321 is provided with a first mounting area 3211 and a second mounting area 3212, and each of the first mounting area 3211 and the second mounting area 3212 is provided with a material picker component 322.

[0080] Each material handling component 322 includes several vacuum suction cups 3221, and each vacuum suction cup 3221 is mounted on the material handling frame 321.

[0081] Understandably, the material handling rack 321 is divided into a first mounting area 3211 and a second mounting area 3212. This partitioned design allows the material handling mechanism 32 to organize and execute picking and placing tasks more efficiently. For example, the first mounting area 3211 can be specifically used to store and pick up metal parts to be injection molded, while the second mounting area 3212 is responsible for retrieving processed materials. Alternatively, both can be flexibly configured according to the actual production process, improving the smoothness and efficiency of operations. The vacuum suction cup 3221 is particularly suitable for handling fragile or high-surface-finish metal parts, avoiding scratches or deformations that may be caused by traditional clamping methods, and significantly improving the processing quality of the product.

[0082] This embodiment simplifies material flow paths, reduces changeover time, and increases production cycle time. Furthermore, the number and layout of suction cups can be quickly adjusted according to production needs, increasing system flexibility and responsiveness.

[0083] like Figure 3 and Figure 5As shown, in some embodiments of the embedded injection molding equipment 10, the material handling device 3 further includes a positioning mechanism 33, which includes a plurality of positioning fixtures 331, each of which has a positioning groove 3311, which is adapted to the metal part 20.

[0084] The positioning groove 3311 is used to position the inserted metal part 20, thereby determining the relative position of the metal part 20 and the picking rack 321 when the picking device 3 takes out the metal part 20.

[0085] Understandably, each positioning fixture 331 is provided with a positioning groove 3311 that matches the outer contour of the metal part 20, ensuring that the metal part 20 can be quickly and correctly aligned when operated by the material handling device 3, preventing processing errors or damage caused by positional deviations. The positioning groove 3311 ensures that the metal part 20 maintains a preset accurate position when gripped by the material handling mechanism 322 (such as a vacuum chuck), achieving positional consistency during each material handling, thereby improving the consistency of finished products in each injection molding process and reducing the product defect rate. The positioning fixture 331 and the positioning groove 3311 can be configured according to the size and shape of different metal parts.

[0086] The pet scissors of this utility model include a metal part 20, which is injection molded with plastic on an injection molding device 1.

[0087] Understandably, the metal part 20 can be the blade of a pet scissor or other metal components. During processing, the metal part 20 is precisely positioned in the injection molding device 1. Subsequently, thermoplastic material is heated to a fluid state and then injected into the mold, tightly wrapping the predetermined portion of the metal part 20. As the plastic cools and solidifies, the plastic material and the metal part are tightly bonded together, forming a composite structure that is both robust and possesses a specific functional form. In this way, the plastic not only provides additional protection for the metal part but may also form the handle portion of the scissors, anti-slip textures, or structural components that enhance the overall stability of the scissors, such as the plastic shell or finger supports.

[0088] The following are the beneficial effects of implementing this utility model:

[0089] This utility model relates to an embedded injection molding device, in which pet scissors are manufactured by processing metal parts on the embedded injection molding device. On the embedded injection molding device, a feeding device automatically pushes the metal parts, and a picking device allows the metal parts to be automatically, quickly, and accurately placed into the injection molding device for injection molding. This allows the plastic material to be automatically injected into the predetermined position on the metal parts, thereby forming the required material, i.e., forming the pet scissors. After injection molding, the picking device removes the material from the injection molding device and places the metal parts to be processed back into the injection molding device.

[0090] This greatly eliminates the tedious manual handling of metal parts and pet scissors, effectively improving production efficiency. It also eliminates errors caused by manual operation, improves the consistency of product production, and increases the yield rate of products.

[0091] The present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
