[0002] The MDA (Model Driven Architecture) frame is a crucial component in mobile devices. During the injection molding process, excess sprue marks may remain around the edges of the MDA frame. Therefore, these excess sprue marks need to be removed to ensure product quality.
[0003] Currently, the sprue gates of mid-frame products are usually removed using a punching fixture, which cuts off the sprue gate with a cutting blade.
[0004] However, during the punching process, the thick sprue residue leads to significant tool wear and can even cause tool breakage. Furthermore, after punching, the cut edge is prone to deformation and tearing of the product, resulting in damage to the dense layer and the formation of pinholes. Utility Model Content

[0011] In one optional implementation, the upper mold further includes: A second telescopic drive member is disposed on the upper mold base, and the second telescopic drive member is used to drive the upper folding knife to move. The second connector is slidably disposed on the side of the abutment opposite to the lower mold. The second connector is connected to the telescopic end of the second telescopic drive member, and the plurality of upper folding blades are all connected to the second connector.
[0012] In one optional implementation, the upper mold further includes: A second guide post and a second guide sleeve are adapted to each other. The second guide post is slidably disposed in the second guide sleeve. One of the abutment and the second connector is provided with the second guide post, and the other is provided with the second guide sleeve.

[0016] This utility model provides a product sprue removal fixture. In the initial state, the upper and lower molds are separated, the product is placed on the support, and then the upper and lower molds come together to close. The supporting member presses on the product. At this time, the lower folding blade can pass through the first through hole and push upward against the sprue, while the upper folding blade can pass through the second through hole and push downward against the sprue. In this way, the upper and lower folding blades continuously and alternately extend and retract, achieving the purpose of repeatedly bending the sprue upward and downward, causing the sprue to break and fall off when the bending point exceeds the material fatigue limit. Thus, by bending the sprue upward and downward instead of punching it, wear and damage to the upper and lower folding blades are reduced, the tool life is extended, and the time for replacing tools due to wear or other damage is saved. This ensures the stability of mass production. Moreover, the method of bending the sprue upward and downward is stable and efficient. The sprue will not cause damage to the dense layer of the product or cause pinholes due to the huge stress generated by violent punching, thus improving the stability of the product structure and ensuring certain quality requirements.

[0024] The following is combined with Figures 1 to 4 This describes a product sprue removal fixture according to an embodiment of the present utility model.
[0025] According to an embodiment of this utility model, a product sprue removal fixture is provided, for example, for removing sprues from MDA-type mid-frame products with side-entry glue in a two-plate mold. Figure 1 As shown, the product's sprue removal fixture includes an upper mold 2 and a lower mold 1 whose distance between them is adjustable (i.e., they can move closer or further apart, changing the distance between the upper mold 2 and the lower mold 2). Specifically, as... Figure 1 As shown, both the upper mold 2 and the lower mold 1 are movable, allowing them to move closer or further apart, thus enabling the upper and lower molds to complete mold closing and opening actions. Alternatively, one of the upper mold 2 and the lower mold 1 is movable while the other is fixed, allowing them to move closer or further apart, thus enabling the upper and lower molds to complete mold closing and opening actions. Optionally, in this embodiment, the lower mold 1 is fixed and remains stationary; the upper mold 2 is movable and can move up and down relative to the lower mold 1, allowing the upper mold 2 to move closer to or further away from the lower mold 1, thereby achieving mold closing and opening actions.
[0026] like Figure 2As shown, the lower mold 1 includes a lower mold base 101 and a lower folding blade 102. The lower mold base 101 is provided with a support member 1011 for placing the product 3, and the support member 1011 is provided with a first through hole 10111 corresponding to the sprue 301 of the product 3. Specifically, the support member 1011 is a support plate, and the support plate is provided with a positioning part 10112 adapted to the hollow part 302 of the product 3. When the product 3 is placed on the support member 1011, the positioning part 10112 is inserted into the hollow part 302, thereby preventing the product 3 from sliding on the surface of the support member 1011, ensuring that the sprue 301 is aligned with the first through hole 10111, and facilitating the subsequent removal of the sprue 301.
[0027] Furthermore, the lower mold base 101 also includes a lower mounting plate 1012 and a plurality of lower support columns 1013. The plurality of lower support columns 1013 are spaced apart between the support member 1011 and the lower mounting plate 1012 to form a lower frame structure, providing support and installation space for other components of the lower mold 1.
[0028] like Figure 2 As shown, the lower folding blade 102 is slidably disposed in the first through hole 10111, and the lower folding blade 102 can move in a direction toward or away from the upper mold 2. That is, the lower folding blade 102 can move up and down along the Z direction in the figure, i.e., it can extend or retract into the first through hole 10111. The lower folding blade 102 is used to push against the sprue 301, so that the sprue 301 bends toward the upper mold 2. That is, as shown... Figure 1 As shown, when the upper mold 2 and the lower mold 1 are in the closed state, the lower folding knife 102 extends upward, which can cause the sprue 301 to bend upward.
[0029] like Figure 3 As shown, the upper mold 2 includes an upper mold base 201 and an upper folding blade 202. The upper mold base 201 is provided with a supporting member 2011 opposite to the supporting member 1011, and the supporting member 2011 is provided with a second through hole 20111 corresponding to the first through hole 10111. Figure 1 As shown, when the upper mold 2 and the lower mold 1 are in the closed state, the abutment 2011 is opposite to the support 1011, which restricts the Z-direction movement space of the product 3 so as to bend the sprue 301.
[0030] Furthermore, the upper mold base 201 also includes an upper mounting plate 2012 and multiple upper support columns 2013. The multiple upper support columns 2013 are spaced apart between the upper mounting plate 2012 and the abutment member 2011 to form an upper frame structure, providing support and installation space for other components of the upper mold 2.
[0031] like Figure 3As shown, the upper folding blade 202 is slidably disposed in the second through hole 20111, and the upper folding blade 202 can move in a direction toward or away from the lower mold 1. That is, the upper folding blade 202 can move up and down along the Z direction in the figure, i.e., it can extend or retract into the second through hole 20111. The upper folding blade 202 is used to push against the sprue 301, so that the sprue 301 bends toward the lower mold 1. That is, as shown... Figure 1 As shown, when the upper mold 2 and the lower mold 1 are in the closed state, the upper folding knife 202 extends downward, which can cause the sprue 301 to bend downward.
[0032] Specifically, during operation, in the initial state, the upper and lower molds are separated, and the product 3 is placed on the support member 1011. Before the upper and lower molds close, the upper folding blade 202 extends downward through the second through hole 20111, while the lower folding blade 102 is in a retracted state. When the upper and lower molds come close together and close, the abutment member 2011 presses on the product 3 and cooperates with the support member 1011 to prevent the product 3 from moving along the Z direction. At this time, the downward-extending upper folding blade 202 pushes the sprue 301 downward, forming a downward bending angle, such as a 45° bending angle. After completing the downward bending action, the upper folding blade 202 retracts upward, while the lower folding blade 102 extends upward through the first through hole 10111. At this time, the upward-extending lower folding blade 102 pushes the sprue 301 upward again until an upward bending angle, such as a 45° bending angle, is formed.
[0033] This process is repeated continuously, alternating between upward and downward bending, until the fatigue limit of the sprue 301 material is exceeded, causing it to fracture and fall off, thus removing the sprue 301. To facilitate the downward fall of the sprue 301, at the final stage, the upper bending blade 202 is extended downwards, while the lower bending blade 102 is retracted downwards. This misalignment between the extended upper bending blade 202 and the retracted lower bending blade 102 allows the sprue 301 to fall smoothly.
[0034] With this setup, product 3 is placed in the lower mold 1. After the upper and lower molds are closed, the upper and lower folding blades continuously and alternately extend and retract, achieving the purpose of bending the sprue 301. This causes the sprue 301 to break and fall off at the bending point because it exceeds the material fatigue limit. Therefore, by bending the sprue 301 rather than punching it, wear and damage to the upper and lower folding blades are reduced, extending the tool life and saving time that would otherwise be required to replace the blades due to wear or other damage. This ensures the stability of product 3 in mass production. Furthermore, the method of bending the sprue 301 is stable and efficient. The sprue 301 will not be damaged due to the enormous stress generated by violent punching, thus preventing the dense layer of product 3 from being destroyed or causing pinholes. This improves the structural stability of product 3 and ensures certain quality requirements for product 3.
[0035] In some embodiments of this utility model, such as Figure 2As shown, the number of downward folding blades 102 is at least two, and the multiple downward folding blades 102 are distributed at intervals along the circumference of the product 3. Accordingly, as Figure 3 As shown, there are at least two upper folding blades 202, and multiple upper folding blades 202 correspond one-to-one with multiple lower folding blades 102. It should be noted that the number of upper and lower folding blades needs to be determined based on the number of sprue 301 on product 3.
[0036] For example, taking product 3 as the MDA frame as an example to illustrate this embodiment, then, as Figure 2 As shown, there are four downward folding blades 102, spaced apart around the perimeter of the product 3. The support member 1011 has four first through holes 10111, and each downward folding blade 102 moves up and down within its corresponding first through hole 10111. Figure 3 As shown, there are four upper folding blades 202, and the supporting member 2011 has four second through holes 20111. Each upper folding blade 202 moves up and down in the corresponding second through hole 20111. It can be understood that the specific structure of the multiple folding blades and through holes needs to be determined according to the specific setting of the multiple sprue outlets 301.
[0037] This setup, with multiple upper and lower folding blades, allows for the simultaneous removal of multiple sprue marks 301 from product 3 in a single operation, improving equipment efficiency, ensuring product 3 quality stability, and reducing the labor intensity of operators.
[0038] In some embodiments of this utility model, such as Figure 2 As shown, the lower mold 1 also includes a first telescopic drive member 103 and a first connecting member 104. Specifically, as... Figure 2 As shown, the first telescopic drive member 103 is disposed on the lower mold base 101. Specifically, the first telescopic drive member 103 is mounted on the upper surface of the lower mounting plate 1012. The first telescopic drive member 103 is used to drive the lower folding blade 102 to move, thereby enabling the lower folding blade 102 to extend upward or retract downward. Specifically, the first telescopic drive member 103 can be a cylinder, electric cylinder, hydraulic cylinder, electric telescopic rod, etc.
[0039] like Figure 2 As shown, the first connecting member 104 can be a connecting plate. The first connecting member 104 is slidably disposed on the side of the support member 1011 opposite to the upper mold 2, that is, located below the support member 1011. The first connecting member 104 is connected to the telescopic end of the first telescopic drive member 103, and multiple downward folding blades 102 are all connected to the first connecting member 104. Specifically, the downward folding blades 102 and the first connecting member 104 can be connected by bolts for quick disassembly and assembly, facilitating later maintenance and replacement.
[0040] With this configuration, the first telescopic drive member 103 can drive multiple downward folding blades 102 to extend and retract simultaneously via the first connector 104, ensuring effective power transmission and synchronization between the various downward folding blades 102. This helps to simplify the mechanical structure and improve the stability and reliability of the system.
[0041] Furthermore, the number of first telescopic drive members 103 is at least two, and the telescopic ends of multiple first telescopic drive members 103 are connected to the first connector 104, thereby helping to distribute the load of individual drive members and improve the stability and durability of the system. It should be noted that in order to ensure that multiple downward folding blades 102 can move synchronously, the telescopic speed and timing of multiple first telescopic drive members 103 need to be precisely controlled.
[0042] In some embodiments of this utility model, such as Figure 2 As shown, the lower mold 1 also includes a first guide post 105 and a first guide sleeve 106 that are adapted to each other. The first guide post 105 is slidably disposed in the first guide sleeve 106. One of the support member 1011 and the first connecting member 104 is provided with the first guide post 105, and the other is provided with the first guide sleeve 106. That is, the support member 1011 is provided with the first guide post 105, and the first connecting member 104 is correspondingly provided with the first guide sleeve 106. Alternatively, the first connecting member 104 is provided with the first guide post 105, and the support member 1011 is correspondingly provided with the first guide sleeve 106.
[0043] For example, such as Figure 2 As shown, the support member 1011 is provided with a first guide post 105. Specifically, the first guide post 105 can be connected to the support member 1011 by welding, bonding, bolting, or other methods. Correspondingly, the first connecting member 104 is provided with a cooperating first guide sleeve 106. Specifically, the first guide sleeve 106 can be connected to the first connecting member 104 by welding, bonding, bolting, or other methods. The first guide post 105 passes through the first guide sleeve 106 and can slide along the first guide sleeve 106.
[0044] With this configuration, when the first telescopic drive member 103 drives the first connecting member 104 to move up and down along the Z direction, the first guide post 105 and the first guide sleeve 106 cooperate with each other to guide the movement of the lower folding blade 102, ensuring the sliding stability and reliability of the lower folding blade 102 and improving the overall performance and reliability of the equipment.
[0045] Preferably, the number of first guide posts 105 and first guide sleeves 106 is at least two sets, and multiple sets of first guide posts 105 and first guide sleeves 106 are distributed at intervals to further improve the stability and accuracy of the movement.
[0046] In some embodiments of this utility model, such as Figure 2As shown, there are multiple first through holes 10111. The lower mold 1 also includes a material discharge port 1014 and a guide cylinder 107. The material discharge port 1014 is disposed on the lower mold base 101, and the material discharge port 1014 corresponds to at least one first through hole 10111. Specifically, the material discharge port 1014 is disposed on the lower mounting plate 1012. The guide cylinder 107 is connected between the first through hole 10111 and the material discharge port 1014. Specifically, the guide cylinder 107 is located between the support member 1011 and the lower mounting plate 1012. One end of the guide cylinder 107 is connected to the first through hole 10111, and the other end is connected to the material discharge port 1014. The guide cylinder 107 is provided with a connecting ear plate 1071. The connecting ear plate 1071 can be connected to the lower mounting plate 1012 by means of bolts or other methods to lock the guide cylinder 107.
[0047] With this configuration, when the sprue 301 falls from the first through hole 10111, it can fall into the discharge port 1014 along the guide cylinder 107, thereby guiding the sprue 301 and ensuring that the sprue 301 can smoothly reach the discharge port 1014, preventing the sprue 301 from splashing everywhere, and facilitating the subsequent centralized collection and treatment of the sprue 301.
[0048] Furthermore, such as Figure 2 As shown, the number of first through holes 10111 is at least two, so the number of material discharge port 1014 and guide cylinder 107 is at least two, and the first through holes 10111, guide cylinder 107 and material discharge port 1014 are arranged in a one-to-one correspondence.
[0049] In some embodiments of this utility model, such as Figure 3 As shown, the upper mold 2 also includes a second telescopic drive member 203 and a second connecting member 204. Specifically, as... Figure 3 As shown, the second telescopic drive member 203 is disposed on the upper mold base 201. Specifically, the second telescopic drive member 203 is mounted on the upper surface of the abutment member 2011. The second telescopic drive member 203 is used to drive the upper folding blade 202 to move, thereby enabling the upper folding blade 202 to extend downward or retract upward. Specifically, the second telescopic drive member 203 can be a cylinder, electric cylinder, hydraulic cylinder, electric telescopic rod, etc.
[0050] like Figure 3As shown, the second connecting member 204 can be a connecting plate. The second connecting member 204 is slidably disposed on the side of the abutment member 2011 opposite to the lower mold 1, that is, above the abutment member 2011. The second connecting member 204 is connected to the telescopic end of the second telescopic drive member 203. Specifically, the upper mold 2 also includes a transition connecting member 209, which is a Z-shaped connecting block. One end of the connecting block is connected to the telescopic end of the second telescopic drive member 203 by a bolt, and the other end is connected to the second connecting member 204 by a bolt. Furthermore, multiple upper folding blades 202 are all connected to the second connecting member 204. Specifically, the upper folding blades 202 and the second connecting member 204 can be connected by bolts for quick disassembly and assembly, facilitating later maintenance and replacement.
[0051] With this configuration, the second telescopic drive 203 can drive multiple upper folding blades 202 to extend and retract simultaneously via the second connector 204, ensuring precise synchronization and coordination between the upper folding blades 202 and improving the stability and reliability of the system.
[0052] Furthermore, the number of second telescopic drive members 203 is at least two, and the telescopic ends of multiple second telescopic drive members 203 are connected to the second connector 204, thereby helping to distribute the load of individual drive members and improve the stability and durability of the system. It should be noted that in order to ensure that multiple upper folding blades 202 can move synchronously, the telescopic speed and timing of multiple second telescopic drive members 203 need to be precisely controlled.
[0053] In some embodiments of this utility model, such as Figure 3 As shown, the upper mold 2 also includes a compatible second guide post 205 and a second guide sleeve 206, with the second guide post 205 slidably disposed within the second guide sleeve 206. One of the supporting member 2011 and the second connecting member 204 is provided with the second guide post 205, and the other is provided with the second guide sleeve 206. That is, the supporting member 2011 is provided with the second guide post 205, and the second connecting member 204 is correspondingly provided with the second guide sleeve 206. Alternatively, the second connecting member 204 is provided with the second guide post 205, and the supporting member 2011 is correspondingly provided with the second guide sleeve 206.
[0054] For example, such as Figure 3 As shown, the supporting member 2011 is provided with a second guide post 205. Specifically, the second guide post 205 can be connected to the supporting member 2011 by welding, bonding, bolting, or other methods. Correspondingly, the second connecting member 204 is provided with a cooperating second guide sleeve 206. Specifically, the second guide sleeve 206 can be connected to the second connecting member 204 by welding, bonding, bolting, or other methods. The second guide post 205 passes through the second guide sleeve 206 and can slide along the second guide sleeve 206.
[0055] With this configuration, when the second telescopic drive member 203 drives the second connecting member 204 to move up and down along the Z direction, the second guide post 205 and the second guide sleeve 206 cooperate with each other to guide the movement of the upper folding blade 202, ensuring the stable and reliable movement of the upper folding blade 202 and improving the overall performance and reliability of the equipment.
[0056] Preferably, the number of second guide posts 205 and second guide sleeves 206 is at least two sets, and multiple sets of second guide posts 205 and second guide sleeves 206 are distributed at intervals to further improve the stability and accuracy of the movement.
[0057] In some embodiments of this utility model, the product sprue 301 removal fixture further includes a compatible third guide post 4 and a third guide sleeve 5, with the third guide post 4 slidably disposed within the third guide sleeve 5. One of the supporting member 2011 and the supporting member 1011 is provided with the third guide post 4, and the other is provided with the third guide sleeve 5. That is, the supporting member 2011 is provided with the third guide post 4, and the supporting member 1011 is correspondingly provided with the third guide sleeve 5. Alternatively, the supporting member 1011 is provided with the third guide post 4, and the supporting member 2011 is correspondingly provided with the third guide sleeve 5.
[0058] For example, such as Figure 4 As shown, the supporting member 2011 is provided with a third guide post 4. Specifically, the third guide post 4 can be connected to the supporting member 2011 by welding, bonding, bolting, or other methods. Correspondingly, the supporting member 1011 is provided with a cooperating third guide sleeve 5. Specifically, the third guide sleeve 5 can be connected to the supporting member 1011 by welding, bonding, bolting, or other methods. The third guide post 4 extends into the third guide sleeve 5 and can slide along the third guide sleeve 5.
[0059] With this configuration, during the mold closing process of the upper mold 2 and the lower mold 1, the third guide post 4 and the third guide sleeve 5 cooperate with each other to guide the movement of the upper and lower molds, ensuring that the first through hole 10111 and the second through hole 20111 are aligned, so that the upper and lower folding blades can accurately bend the sprue 301.
[0060] Preferably, the number of third guide posts 4 and third guide sleeves 5 is at least two sets, and multiple sets of third guide posts 4 and third guide sleeves 5 are distributed at intervals to further improve the stability and accuracy of mold closing.
[0061] In some embodiments of this utility model, such as Figure 3As shown, the upper mold 2 also includes a product clamping member 207, which can be a product pressing block. The shape of the product pressing block can be consistent with the shape of the product 3 so that the product pressing block and the product 3 fit tightly together. The product clamping member 207 is located on the side of the supporting member 2011 facing the lower mold 1, that is, below the supporting member 2011. The product clamping member 207 is used to clamp and fix the product 3. Specifically, the product clamping member 207 can be connected to the supporting member 2011 by means of bolts or the like. The product clamping member 207 is also provided with a first clearance hole 2071 that matches the positioning part 10112, so that when the product clamping member 207 fits tightly with the product 3, it avoids interference with the positioning part 10112 on the supporting member 1011, thus ensuring reliable fixing of the product 3.
[0062] With this configuration, when the upper mold 2 and the lower mold 1 are in the closed state, the product clamping component 207 can further clamp and fix the product 3, so that the product 3 will not move, thereby ensuring that the upper and lower folding blades can accurately bend the sprue 301 and remove the sprue 301 efficiently and reliably.
[0063] In some embodiments of this utility model, such as Figure 3 As shown, the upper mold 2 also includes at least one suction cup 208, wherein the number and arrangement of the suction cups 208 can be specifically determined according to actual design requirements. The suction cup 208 is disposed on the side of the supporting member 2011 facing the lower mold 1, that is, located on the lower surface of the supporting member 2011. The product clamping member 207 is provided with a second clearance hole 2072 for the suction cup 208 to pass through, and the suction cup 208 is used to hold the product 3. Specifically, the suction cup 208 passes through the second clearance hole 2072 and can be threadedly connected to the supporting member 2011.
[0064] With this configuration, when the upper mold 2 and lower mold 1 are in the closed state, the suction cup 208 simultaneously contacts and holds the product 3. After the sprue 301 is repeatedly removed by bending, the upper mold 2 and lower mold 1 separate. At this time, the product 3 with the sprue 301 removed can move with the upper mold 2, making it easy to remove the processed product 3. The product 3 with the sprue 301 to be removed can then be placed again in the lower mold 1, thereby speeding up the production cycle, improving the working efficiency of the equipment, and ensuring the efficient and reliable operation of the equipment.
[0065] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
