Description

Technical Field

[0001] This application relates to the technical field of receiving materials, and more specifically, to a receiving mechanism and a mold. Background Technology

[0002] Electronic products undergo injection molding during manufacturing, which involves conveying material via a conveyor belt. In existing technology, the conveyor belt is manually installed into the molding machine. After each reel is used, the machine is stopped for 20 to 30 minutes while the next reel is manually installed before resuming operation. This process is time-consuming for reel changes, hinders continuous production, results in low efficiency, and is labor-intensive for workers. Summary of the Invention

[0003] This application provides a material receiving mechanism and a mold to solve the problem that existing molds cannot achieve continuous production and have low production efficiency during injection molding.

[0004] A receiving mechanism according to this application includes: a base having a worktable, the worktable including a piercing worktable area and a connecting worktable area; a connecting component including a piercing structure and a connecting structure, the piercing structure being disposed corresponding to the piercing worktable area and the connecting structure being disposed corresponding to the connecting worktable area; and a pressing component, the piercing worktable area and the connecting worktable area being located within the orthographic projection of the pressing component, the pressing component having a waiting state away from the connecting component and a working state close to the connecting component.

[0005] Furthermore, the puncture structure includes multiple needles, which are disposed on the base and located at the lower part of the worktable, with the conical part of the needles facing upwards.

[0006] Furthermore, the pressing assembly includes a driving part and a pressing structure, the driving part being fixed on the base, and the pressing structure being fixedly connected to the driving part.

[0007] Furthermore, the pressing structure includes a pressing plate, a pressing block, a perforated column, a first elastic member, and a second elastic member. The pressing plate is connected to the driving part, and the pressing plate and the pressing block are connected through the first elastic member. The pressing block has a mounting hole, and the perforated column is movably installed at least partially in the mounting hole. The second elastic member is located between the pressing plate and the perforated column, and the perforated column is arranged correspondingly to the needle.

[0008] Furthermore, the length of the first elastic member located between the pressure plate and the pressure block is greater than the length of the second elastic member located between the pressure plate and the pressure block.

[0009] Furthermore, the pressure-blocking structure also includes a cutting block, which is connected to the pressure plate.

[0010] Furthermore, there are two piercing structures, located on opposite sides of the cutting block.

[0011] Furthermore, the connecting structure includes a riveting post, which is connected to the pressure plate.

[0012] Furthermore, the end of the rivet post away from the pressure plate is a slope, which protrudes from the edge of the rivet post toward the central axis of the rivet post in a direction away from the pressure plate.

[0013] According to another aspect of this application, a mold is also provided, including a mold body and a receiving mechanism, wherein the receiving structure is the receiving mechanism described above.

[0014] By applying the technical solution of this application, when the material strip is about to run out, the current material strip and the next material strip are placed in the piercing worktable area and pierced. Then, the two material strips are placed in the connecting worktable area to connect them. In this way, the mold can be made continuously without stopping, thus improving efficiency. The technical solution of this application effectively solves the problem of low production efficiency in existing molds during injection molding, which prevents continuous production.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] like Figures 1 to 5 As shown, the receiving mechanism of this embodiment includes a base 10 and a connecting component 20. The base 10 has a worktable 11, which includes a piercing worktable area and a connecting worktable area. The connecting component 20 includes a piercing structure 21 and a connecting structure 22, with the piercing structure 21 corresponding to the piercing worktable area and the connecting structure 22 corresponding to the connecting worktable area. A pressing component 30 is also included, with both the piercing worktable area and the connecting worktable area located within its orthographic projection. The pressing component 30 has a waiting state away from the connecting component 20 and a working state close to the connecting component 20.

[0028] By applying the technical solution of this embodiment, when the material strip 100 is about to run out, the material strip 100 and the next material strip 100 are placed in the piercing worktable area, and both material strips 100 are pierced. Then, the two material strips 100 are placed in the connecting worktable area to connect them. In this way, the mold can be made continuously without stopping, thus improving efficiency. The technical solution of this application effectively solves the problem that existing molds cannot achieve continuous production and have low production efficiency during injection molding.

[0029] It should be noted that the piercing structure 21 is configured correspondingly to the piercing worktable area, and the piercing structure 21 is located within the orthographic projection of the piercing worktable area. The connecting structure 22 is configured correspondingly to the connecting worktable area, and the connecting structure 22 is located within the orthographic projection of the connecting worktable area. The connecting structure 22 is a riveting structure.

[0030] like Figure 4 As shown, in this embodiment, the piercing structure 21 includes multiple needles, which are disposed on the base 10 and located at the lower part of the worktable 11, with the conical portion of the needles facing upwards. The needles can pierce the strip 100. Because the needles are positioned at the lower part of the worktable 11 with their conical portions facing upwards, when the needles and strip 100 move relative to each other, the needles pierce the strip 100 and create a flange 110, preparing for subsequent riveting. It should be noted that the multiple needles are arranged correspondingly to the two sides of the strip 100, resulting in more even force distribution on the strip 100. During riveting, the two sides of the strip 100 can also be fixed, leading to a better connection between the two strips 100 after riveting. In this embodiment, there is one needle on each side of the strip 100, and the two needles are symmetrically arranged along the extension direction of the strip 100.

[0031] like Figures 1 to 3 As shown, in this embodiment, the pressing component 30 includes a driving part 31 and a pressing structure 32. The driving part 31 is fixed on the base 10, and the pressing structure 32 is fixedly connected to the driving part 31. The above structure is compact. A mounting frame is provided on the upper part of the base 10, and the pressing component is mounted on the mounting frame. The piercing and connection of the material strip 100 can be achieved by driving the pressing structure 32 up and down through the driving part 31.

[0032] It should be noted that the two material strips 100 to be connected can be placed on the workbench 11 manually or by a robotic arm. Neither method will cause the machine to stop, thus not affecting work efficiency. The drive unit 31 can be hydraulically driven, pneumatically driven, or electrically driven, etc. In this embodiment, pneumatic drive is used. The drive unit 31 includes a cylinder and a piston rod, with the piston rod located within the cylinder. The pressing structure 32 is fixedly connected to the piston rod.

[0033] In this embodiment, the receiving structure further includes two guide plates for the material strip 100, which are respectively disposed on both sides of the base 10 for placing the material strip 100. Each guide plate includes an inclined plate and a flat plate, which are integrally formed. The flat plate is located near the center of the base 10, while the inclined plate is located at the edge of the base. The inclined plate gradually rises from away from the flat plate to closer to it. The guide plates are connected to the base 10 by fasteners. The base 10 has elongated holes extending vertically, allowing adjustment of the tilt angle and height of the guide plates.

[0034] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the pressing structure 32 includes a pressing plate, a pressing block, a perforated post 324, a first elastic member 321, and a second elastic member 322. The pressing plate is connected to the driving part 31, and the pressing plate and the pressing block are connected through the first elastic member 321. The pressing block has a mounting hole, and the perforated post 324 is movably installed at least partially in the mounting hole. The second elastic member 322 is located between the pressing plate and the perforated post 324, and the perforated post 324 is correspondingly arranged with the piercing needle. The first elastic member 321 first elastically presses, allowing the piercing needle to pierce the material strip 100. The piercing needle first pierces the material strip 100 to a rivet hole of a predetermined size. The pressing structure 32 continues to move towards the piercing needle, and the second elastic member 322 elastically presses against the perforated post 324, so that the perforated post 324 enters the rivet hole. The above arrangement can ensure that the diameter of the rivet hole meets the requirements.

[0035] It should be noted that the two strips 100 are connected by a connecting strip 200, which overlaps the upper parts of the two strips 100. The connecting strip 200 has corresponding connecting holes, and the flange 110 of the rivet hole passes through the connecting hole. The pressing structure 32 presses against the flange 110 of the rivet hole, so that the flange 110 is riveted together with the connecting strip 200. The end of the rivet post 221 facing the strip 100 has a pressing head. The diameter of the pressing head gradually increases from bottom to top. Under the action of the pressing head, the flange 110 gradually tilts outward before riveting, thus avoiding the problem of riveting failure caused by the pressing head pressing the flange 110 vertically downward when it is flat.

[0036] like Figures 2 to 4As shown, in the technical solution of this embodiment, the length of the first elastic member 321 located between the pressure plate and the pressure block is greater than the length of the second elastic member 322 located between the pressure plate and the pressure block. The greater length of the first elastic member 321 ensures that the strip 100 is pierced first, and the strip 100 has a rivet hole, which is then inspected by the piercing post 324. In the above structure, there are multiple piercing posts 324, and multiple second elastic members 322 are arranged corresponding to each piercing post 324. It should be noted that the end of the piercing post 324 facing the piercing needle has a piercing needle avoidance groove. When the piercing post 324 moves towards the piercing needle, the piercing needle moves relative to the piercing post 324, and the upper part of the piercing needle enters the piercing needle avoidance groove. This allows the piercing post 324 to inspect whether the rivet hole meets the requirements, and also enables effective avoidance and cooperation between the piercing post 324 and the piercing needle. The lower part of the perforated post 324 has a necked section, which ensures that the perforated post 324 can smoothly enter the rivet hole.

[0037] like Figure 4 As shown, in this embodiment, the pressing structure 32 further includes a cutting block 323 connected to the pressing plate. This structure further improves connection efficiency. The cutting block 323 can cut the ends of the strips 100, ensuring that the distance between the two strips 100 meets requirements during connection, resulting in high distance accuracy. A support tube, which is a square tube or a support platform, is provided corresponding to the cutting block 323. The outline of the cutting block 323 matches the outline of the square tube, allowing for the cutting of both strips 100, including the tail end of the front strip 100 and the head end of the rear strip 100. The receiving mechanism also includes a waste box, located under the platform, to collect cutting waste. In this embodiment, the distance between the beginning and end of the strips 100 is 0.1 mm, and the hole spacing of the front and rear riveting holes is equal to the strip 100 step distance.

[0038] like Figures 1 to 3 As shown, in this embodiment, there are two piercing structures 21, located on opposite sides of the cutting block 323. The two piercing structures 21 improve work efficiency; that is, with each operation of the pressing structure 32, both the front and rear sections of the strip 100 can be pierced simultaneously. The two piercing structures 21 are symmetrically arranged along the central cutting plane (which is perpendicular to the extension direction of the strip 100). It should be noted that the piercing structure 21 also includes a positioning post, which is mounted on the base 10. The positioning post serves to fix the strip 100 and also makes the installation position of the strip 100 more precise. The free end of the positioning post faces upwards, and the diameter of the free end gradually increases towards the bottom, making it easier to install the strip 100.

[0039] like Figure 4As shown, in this embodiment, the connecting structure 22 includes a riveting post 221 connected to a pressure plate. The riveting post 221 facilitates riveting and increases the success rate. The front end of the riveting post 221 is first tilted, and then pressed against the flat surface, making the riveting of the flange more secure. The area of ​​the connecting workbench corresponding to the riveting post 221 is a flat surface with a groove in the middle, allowing the tilted portion of the front of the riveting post to enter the groove, thus ensuring the pressure of the flat surface against the flange. The specific structure of the riveting post 221 is as follows: the end of the riveting post 221 away from the pressure plate is a slope, which protrudes from the edge of the riveting post 221 towards its central axis away from the pressure plate. The inclination angle of the slope is 2° to 8°.

[0040] This application also provides a mold, including a mold body and a receiving mechanism, wherein the receiving structure is the aforementioned receiving mechanism. The mold of this application can achieve continuous operation, greatly improving work efficiency.
