Description

Technical Field

[0001] This utility model relates to the field of card reader shell processing technology, and more specifically, it relates to a molding device for processing SIM card reader shells. Background Technology

[0002] A SIM card reader is a hardware interface circuit that reads information from the inside of a SIM card, similar to the readers for various common memory cards. It can read the phonebook, SMS messages, and other information from the SIM card, and can modify the phonebook for backup. The manufacturing process of the SIM card reader casing requires a molding device. Existing molding devices have a single processing station, requiring cooling after processing before unloading, which affects processing efficiency. They lack suitable multi-station loading mechanisms, and the alignment stability is poor after changing or adjusting the loading mechanism. They also lack suitable reinforcing locking mechanisms. Furthermore, the heat dissipated during cooling results in a high ambient temperature during processing, and there is a lack of suitable, efficient heat dissipation mechanisms. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the problems existing in the prior art, this utility model provides a molding device for processing SIM card reader shells, which solves the technical problems mentioned in the background art, such as the single setting of processing stations, the need for cooling after processing before unloading, which affects processing efficiency, and the lack of a suitable multi-station loading mechanism.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming device for processing the outer shell of a SIM card reader, comprising a worktable, a support on the upper surface of the worktable, a hydraulic cylinder at the top inside the support, an upper mold connected to the bottom end of the hydraulic cylinder, a groove on the upper surface of the worktable, an adjusting seat slidably disposed inside the groove, a lower mold symmetrically disposed on the upper surface of the adjusting seat, an adjusting rod rotatably disposed on the worktable corresponding to the groove, an adjusting hole disposed on the adjusting seat, the adjusting rod and the adjusting hole being threadedly connected, an adjusting motor connected to the outer end of the adjusting rod, a locking plate on the front surface of the worktable, locking rods at the four corners of the rear surface of the locking plate, through holes on the front surface of the worktable corresponding to multiple locking rods, and locking holes on the front surface of the adjusting seat corresponding to multiple locking rods, the locking holes being symmetrically arranged in two sets.

[0007] The present invention is further configured such that guide rods are symmetrically arranged inside the groove, and guide holes are provided on the adjusting seat for each of the two guide rods to guide the sliding.

[0008] The present invention is further configured such that springs are sleeved on the outer ends of the plurality of locking rods, and the springs are connected between the locking plate and the worktable for convenient automatic reset and locking.

[0009] The present invention is further configured such that a gripping rod is provided on the front end face of the locking plate, and a gripping ring is provided at the front end of the gripping rod, so as to facilitate the overall gripping and pulling out.

[0010] The present invention is further configured such that a heat dissipation box is provided above the bracket, an air guide pipe is provided through the upper end face of the heat dissipation box, a fan is provided inside the air guide pipe, and air suction pipes are provided through the left and right end faces of the heat dissipation box. Both air suction pipes extend downward through the bracket to facilitate heat dissipation.

[0011] The present invention is further configured such that the bottom ends of both suction pipes are provided with suction hoods corresponding to the lower mold to ensure heat absorption effect.

[0012] The present invention is further configured such that each of the two suction pipes is equipped with a control valve, and each of the two suction hoods is equipped with a filter screen, which facilitates the opening and closing adjustment of the suction pipes and provides dust protection for the heat absorption end.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a forming device for processing the shell of a SIM card reader, which has the following advantages:

[0015] 1. The adjustable seat design allows the motor-driven threaded adjusting rod to slide within a groove, enabling two symmetrically arranged lower dies to move alternately to the processing position. While one set of lower dies is in the stamping process, the other set can simultaneously undergo cooling, demolding, cleaning, or pre-loading of blanks, achieving continuous production. This design significantly reduces downtime associated with traditional single-die changes.

[0016] 2. Through the design of the heat dissipation box, an active air-cooling system is constructed using fans and air ducts. Combined with suction pipes and hoods extending to the mold area, the heat generated during molding is directionally extracted. The suction hood faces the mold station and, together with a filter screen, blocks debris. Control valves allow for opening and closing adjustments on both sides. This solution avoids the energy waste of overall workshop cooling and achieves rapid cooling of the mold surface (more than 60% faster than natural cooling).

[0017] 3. Through the design of the locking plate, the locking plate engages with multiple sets of locking holes on the adjusting seat via locking rods with pre-compressed springs at the four corners. When the adjusting seat moves to the target position, multiple springs retract, causing the locking rods and locking plate to slide back to their original positions. After passing through the through holes, the locking rods are inserted into the corresponding set of locking holes, ensuring alignment and locking after position adjustment.

[0027] Please see Figures 1-4A forming device for processing the outer shell of a SIM card reader includes a worktable 1, a support 2 on the upper surface of the worktable 1, a hydraulic cylinder 3 at the top inside the support 2, an upper mold 4 connected to the bottom end of the hydraulic cylinder 3, a groove 5 on the upper surface of the worktable 1, an adjusting seat 6 slidingly inside the groove 5, a lower mold 7 symmetrically arranged on the upper surface of the adjusting seat 6, an adjusting rod 8 rotatably arranged on the worktable 1 corresponding to the groove 5, an adjusting hole 26 on the adjusting seat 6, the adjusting rod 8 and the adjusting hole 26 being threadedly connected, an adjusting motor 9 connected to the outer end of the adjusting rod 8, a locking plate 10 on the front surface of the worktable 1, locking rods 11 at the four corners of the rear surface of the locking plate 10, through holes 12 corresponding to multiple locking rods 11 on the front surface of the worktable 1, and locking holes 13 corresponding to multiple locking rods 11 on the front surface of the adjusting seat 6, with two sets of locking holes 13 symmetrically arranged.

[0028] In this embodiment, the adjusting seat 6 slides relative to the groove 5, adjusting the lower mold 7 to be formed to the corresponding position of the upper mold 4. The locking rod 11 at the rear end of the locking plate 10 passes through the through hole 12 and is inserted into the locking hole 13 to lock the position of the adjusting seat 6, ensuring alignment accuracy. The hydraulic cylinder 3 drives the upper mold 4 to press down. The upper mold 4 and the lower mold 7 cooperate to form the raw material in the lower mold 7. After initial cooling, the hydraulic cylinder 3 retracts, the upper mold 4 rises, and the locking rod 11 is pulled out to adjust the overall position of the adjusting seat 6. The lower mold 7 on the other side is adjusted to the position to be processed. After processing, the lower mold 7 is adjusted to the outside for further cooling.

[0029] More specifically, when the adjusting seat 6 is slidably adjusted, the control device has its own control system. The adjusting motor 9 is started, and the adjusting motor 9 drives the adjusting rod 8 to rotate. The adjusting rod 8 and the adjusting hole 26 are threaded together to realize the sliding adjustment drive. Before adjustment, the locking rod 11 must be pulled out.

[0030] Please see Figures 2-4 As one embodiment of the adjusting seat 6: guide rods 14 are symmetrically arranged inside the groove 5, and guide holes 15 are opened on the adjusting seat 6 corresponding to the two guide rods 14.

[0031] Specifically, when the adjusting seat 6 slides relative to the groove 5, the guide rod 14 and the guide hole 15 cooperate to slide and guide, ensuring stable position adjustment.

[0032] Please see Figure 1 and Figure 2 As one embodiment of the locking rod 11: a spring 16 is sleeved on the outer end of a plurality of locking rods 11, the spring 16 is connected between the locking plate 10 and the worktable 1, the front end face of the locking plate 10 is provided with a gripping rod 17, and the front end of the gripping rod 17 is provided with a gripping ring 18.

[0033] Specifically, before adjusting the adjusting seat 6, hold the gripping ring 18 and pull the gripping rod 17, locking plate 10 and locking rod 11 outward as a whole. The spring 16 will be stretched and the locking rod 11 will be pulled out from the locking hole 13. After the adjusting seat 6 is adjusted, release the locking ring. Multiple springs 16 will retract synchronously and the locking rod 11 will be reset and inserted into another set of locking holes 13 to achieve quick locking adjustment.

[0034] Please see Figure 1 and Figure 5 As a method of heat dissipation: a heat dissipation box 19 is provided above the bracket 2. A duct 20 is provided through the upper end of the heat dissipation box 19. A fan 21 is provided inside the duct 20. A suction pipe 22 is provided through the left and right ends of the heat dissipation box 19. Both suction pipes 22 extend downward through the bracket 2. A suction hood 23 is provided at the bottom of both suction pipes 22 corresponding to the lower mold 7. A control valve 24 is provided on both suction pipes 22. A filter screen 25 is provided inside both suction hoods 23.

[0035] Specifically, the control device has its own control system. When the fan 21 is started, the control valve 24 of the suction pipe 22 on the cooling side after molding is opened. The fan 21 draws the heat of the product in the lower mold 7 outward through the suction hood 23 and delivers it to the external environment through the suction pipe 22, heat dissipation box 19 and air guide pipe 20, so as to achieve efficient and precise heat dissipation.

[0036] In summary, the overall equipment is in use:

[0037] When the adjustment is in position 6, the control device has its own control system, which starts the adjustment motor 9. The adjustment motor 9 drives the adjustment rod 8 to rotate. The adjustment rod 8 and the adjustment hole 26 are threaded together, and the guide rod 14 and the guide hole 15 are slidably guided, so as to realize the replacement and adjustment of the lower mold 7 on both sides of the upper end face. One side moves to the lower part of the upper mold 4 for forming operation, and the other side moves to the outside to facilitate loading and unloading operations.

[0038] When in cooling and heat dissipation mode, the control device has its own control system, which opens the control valve 24 of the suction pipe 22 above the outer lower mold 7, starts the fan 21, and absorbs the heat emitted through the suction hood 23. The absorbed heat is discharged to the external environment through the air guide pipe 20, which facilitates direct heat dissipation during the production process.

[0039] When the position adjustment is in the locking state, before adjusting the position of the adjusting seat 6, hold the gripping ring 18 and pull the locking plate 10 outward as a whole. The spring 16 will be stretched. After the adjusting seat 6 is adjusted, release the gripping ring 18, the spring 16 will retract, and the locking rod 11 will slide back to its original position. The locking rod 11 will pass through the through hole 12 and be inserted into the corresponding locking hole 13, thereby strengthening the locking of the position adjustment and ensuring the alignment effect of subsequent processing.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
