Description

Technical Field

[0001] This utility model relates to the field of injection molding technology for button battery sealing ring inserts, specifically to an injection molding feeding mechanism and injection molding equipment. Background Technology

[0002] A button cell battery typically consists of a negative electrode cap, a positive electrode shell, a sealing ring, a separator, and an electrolyte. The sealing ring is located between the negative electrode cap and the positive electrode shell. For example, Chinese Patent 202020132600.4 discloses a novel button cell battery, including a lower steel shell, an upper steel shell, and a sealing ring disposed between the lower and upper steel shells, with the upper steel shell having a cut edge at its end. Current manufacturing processes, for ease of assembly, use the metal upper / lower shells of the button cell battery as inserts placed in a mold, and then directly injection mold the sealing ring onto them, achieving integration.

[0003] The existing technology has the following problems: after the sealing ring is injection molded into the metal shell of the button battery, the demolding mechanism pushes it out of the mold, and then the jetting mechanism blows it off the mold. Although the above jetting is fast, the direction of the blown battery shell is not easy to control and it is easy to scatter in various places. Although the baffle has a certain limiting effect, it will rebound and some will still scatter. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an injection molding feeding mechanism and injection molding equipment to solve the technical problem of button battery sealing ring inserts scattering everywhere during injection molding feeding in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides an injection molding blanking mechanism, comprising: Frame; A telescopic mechanism, the movable end of which is connected to the sleeve frame, drives the sleeve frame to move along a first direction; A flow guiding mechanism, connected to the bottom of the telescopic mechanism and arranged in a first direction, is used to receive material pushed within the sleeve frame; and A collection component, fitted onto the bottom of the flow guiding mechanism, is used to receive and collect the materials on the flow guiding mechanism.

[0006] In some embodiments, the flow guiding mechanism includes a ramp and a guide tube, the ramp being connected to one side of the guide tube and the collector abutting against the bottom of the guide tube.

[0007] In some embodiments, baffles extending to the guide tube are provided on both sides of the ramp.

[0012] In some embodiments, the collection component includes a collection basket fitted onto the bottom of the guide tube.

[0013] In some embodiments, the bottom of the guide tube is provided with an extension frame, which abuts against the top or inner wall of the collection basket to seal the gap.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of button battery sealing ring inserts scattering during injection molding, this invention provides an injection molding feeding mechanism. This mechanism uses a frame to enclose and push the demolded button battery casing at the top of the lower mold, causing it to move and detach from the mold, falling into a guiding mechanism and being guided into a collection component for centralized collection. This avoids the unstable feeding direction of jet-type feeding, facilitates centralized collection, reduces cleaning burden, and prevents scattered casings from bouncing into the mold closing area and interfering with subsequent injection molding.

[0020] It should be noted that the injection molding blanking mechanism described in this utility model is used for, but not limited to, the injection molding of button battery sealing ring inserts. For ease of explanation, this utility model only uses the application of the injection molding blanking mechanism to the injection molding of button battery sealing ring inserts as an example. The principle of the injection molding blanking mechanism applied to other types of equipment is essentially the same as that applied to the injection molding of button battery sealing ring inserts, and will not be described in detail here.

[0021] Please see Figure 1-2 This utility model provides an injection molding material feeding mechanism, which includes a frame 1, a telescopic mechanism 2, a flow guiding mechanism 3, and a collecting component 4. The movable end of the telescopic mechanism 2 is connected to the frame 1, driving the frame 1 to move along a first direction. The frame 1 is a square frame that matches the length and width dimensions of the lower mold, allowing the upper mold to move downwards inside the frame 1 and close with the lower mold. The flow guiding mechanism 3 is connected to the bottom of the telescopic mechanism 2 and arranged in the first direction to receive the material pushed inside the frame 1 for demolding. The button battery casing is inside the frame 1. Under the extension and retraction of the telescopic mechanism 2, the frame 1 moves laterally, pushing the button battery casing horizontally to the top of the flow guiding mechanism 3, where it detaches from the mold and falls downward from the inside of the frame 1 into the flow guiding mechanism 3. The collecting component 4 is fitted at the bottom of the flow guiding mechanism 3 to receive and concentrate the material on the flow guiding mechanism 3. The length and width of the collecting component 4 are greater than the length and width of the material discharge point at the bottom of the flow guiding mechanism 3, respectively, to prevent the falling button battery casing and residual glue from scattering to the outside.

[0022] Understandably, the reciprocating extension and retraction of the telescopic mechanism 2 matches the movement and return of the sleeve frame 1 to its initial position, and the sleeve frame 1 matches the mold size to avoid the mold closing of the upper and lower molds; the telescopic mechanism 2 can be a hydraulic push rod, and there are two telescopic mechanisms 2, with the extension and retraction ends of the two telescopic mechanisms 2 respectively connected to the two sides of the sleeve frame 1 parallel to the first direction.

[0023] In one embodiment, please refer to Figure 1 and Figure 2 The flow guiding mechanism 3 includes a ramp 31 and a guide cylinder 32. The ramp 31 is connected to one side of the guide cylinder 32, and the collecting member 4 abuts against the bottom of the guide cylinder 32. The ramp 31 has an inclined surface, allowing the material to slide naturally into the guide cylinder 32 under the action of gravity. The guide cylinder 32 is a vertical or near-vertical cylindrical structure that guides the material to fall into the collecting member 4.

[0024] For further details, please refer to Figure 1 and Figure 2 To ensure that the material does not detach from the ramp 31, baffles 33 extending to the guide cylinder 32 are provided on both sides of the ramp 31. The baffles 33 are integrally formed with the ramp 31 or fixedly connected to it to form a guide channel.

[0025] For further details, please refer to Figure 1 and Figure 2To prevent material from jumping out, the frame 1 includes a frame body 11 and an extension plate 12. The extension plate 12 is connected to the side near the flow guiding mechanism 3 and is slidably connected to the top of the baffle 33 and the guide cylinder 32. The top of the guide cylinder 32 is provided with a cover plate 34. The extension plate 12 is attached to the top of the cover plate 34. The top of the flow guiding mechanism 3 is covered by the cover plate 34 and the extension plate 12 to prevent material from jumping out. The extension plate 12 moves with the frame 1 to form a dynamic cover.

[0026] Understandably, the frame 11 is square, and its inner wall is an outward sloping surface from bottom to top, which can guide the material to slide inward and downward.

[0027] Furthermore, to optimize the smoothness of the material feeding process, the flow guiding mechanism 3 also includes an air jet assembly 35, which is installed on the ramp 31 and has several air jet nozzles 35a arranged on the ramp 31. The air jet assembly 35 is connected to an external air source and sprays airflow through the air jet nozzles 35a to reduce friction and promote material sliding. The extension plate 12 has vent holes 12a opposite to the positions of the air jet nozzles 35a for airflow discharge. Specifically, the air jet assembly 35 sprays air when the extension plate 12 covers the top of the ramp 31. At this time, the cover plate 34 and the extension plate 12 form a seal around the top of the ramp 31 and the guide cylinder 32, as well as the side of the lower mold 200. The air jet can spray the material up and make it fall without popping out.

[0028] Understandably, multiple jet nozzles 35a are connected to a diversion pipe, which has a main pipe connected to a blower to guide the airflow to each jet nozzle 35a, forming an airflow at the ramp 31 position, causing the material stuck on the ramp 31 to rise and slide down, and it will not be ejected to the outside due to the obstruction of the cover plate 34 and the extension plate 12.

[0029] It should be noted that the external air source can not only use a blower for intermittent blowing, but also use a compressed air tank and control valve for intermittent jetting.

[0030] Furthermore, to ensure the stability of the movement of the sleeve frame 1, the ramp 31 is provided with an extension strip 36, the extension strip 36 is provided with an upwardly protruding guide strip 36a, and sleeves 1a are provided on both sides of the bottom of the sleeve frame 1. The guide strip 36a is inserted into the inner side of the sleeve 1a to guide the sleeve frame 1 to slide along the guide strip 36a, so as to avoid the position of the sleeve frame 1 shifting under repeated sliding, and to avoid the sleeve frame 1 shifting position and interfering with the mold closing of the upper and lower molds.

[0031] In one embodiment, please refer to Figure 1 and Figure 2The collecting component 4 includes a collecting basket 41, which is fitted onto the bottom of the guide tube 32 to cover the bottom of the guide tube 32 and prevent the material from falling out.

[0032] Furthermore, in order to completely prevent material from popping out, the bottom of the guide tube 32 is provided with an extension frame 32a, which abuts against the top or inner wall of the collection basket 41 to seal the gap, thereby preventing material from popping out at the collection end.

[0033] Understandably, at locations where material bounce might occur, primarily at the air jet position of ramp 31, the top is sealed by the extension plate 12 and the cover plate 34, allowing the material to only have a downward sliding channel. The bottom is sealed by the matching of the collection basket 41 and the outer frame 32a, blocking any gaps that might arise below, thus forming a relatively closed system for guiding and collecting, preventing the battery casing from bouncing out. Furthermore, during demolding and the movement of the frame 11 pushing the casing, there is no strong instantaneous impact force, and the side walls of the frame 11 also have a shielding function, intercepting small bounces and essentially preventing bounces during the pushing process. Additionally, the reciprocating movement of the frame 11 cleans the top of the lower mold, pushing any bouncing and remaining casing material away from the top of the lower mold, thereby avoiding interference with the next upper and lower mold closing.

[0034] This utility model also provides an injection molding device; please refer to [link / reference]. Figure 3 , Figure 4 , Figure 5 and Figure 6 The injection molding equipment includes a lower mold 200 and a lifting base 300. The lower mold 200 is provided with a plurality of receiving slots 201 for placing button battery casings as inserts. The injection molding equipment also includes an injection unloading mechanism 100 as described in any of the above embodiments, which is installed on the lower mold 200. The lifting base 300 has lifting ends 301 corresponding to the receiving slots 201 one by one, and the lifting ends 301 have three position states: a first position state in which the lifting ends are recessed into the receiving slots 201 and serve as the bottom wall of the receiving slots 201 for inserting the button battery casings; a second position state in which the lifting ends are protruding from the top of the lower mold 200 for ejection and demolding; and a third position state in which the lifting ends are flush with the top of the lower mold 200 for moving the frame 11 to push the casings away from the lower mold.

[0035] It should be noted that the lower mold 200 is the fixed mold, and the lifting base 300 is the demolding mechanism. Other conventional structures of the injection molding equipment are not shown in the figure. The injection molding equipment includes, but is not limited to, the injection unloading mechanism 100, the lower mold 200, and the lifting base 300. For example, conventional injection molding equipment also has other conventional components of existing injection molding machines such as the upper mold and the injection mechanism. Other conventional components of existing injection molding machines are not shown in the figure. The upper mold is the moving mold.

[0036] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: Before injection molding, the lifting end 301 is in the first position, and the button battery shell is inserted into the receiving groove 201; after mold closing and injection molding, the lifting end 301 rises to the second position, ejects the shell as a whole after the sealing ring is formed on the shell, and retracts to the third position, so that the top of the entire lower mold does not have a recessed area for the shell to hide; then the telescopic mechanism 2 drives the sleeve frame 1 to move, pushes the shell to the ramp 31, the shell slides into the guide cylinder 32 along the ramp 31, and finally falls into the collection basket 41 for collection. When the sleeve frame 1 returns to the initial position at the top of the upper mold, the air jet component 35 sprays air to assist in retaining the sliding shell. The entire unloading process is efficient and orderly, avoiding the shell from scattering.

[0037] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
