Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to an injection mold for an optical fiber ceramic connector. Background Art

[0002] As a key component in the optical fiber transmission system, the quality and production efficiency of optical fiber ceramic connectors directly affect the performance of the entire system. In recent years, with the vigorous development of emerging technologies such as big data, cloud computing, and the Internet of Things, the market demand for optical fiber ceramic connectors has grown dramatically.

[0003] In the known prior art, connectors are usually produced by injection molding followed by processing. During injection molding, in order to ensure that the through hole of the connector is unobstructed, the core pin of the injection mold needs to be aligned and inserted into the molding hole on the molding mold. Since the aperture on the optical fiber connector is small, the mold diameter is also correspondingly small. After the injection mold is formed, the mold must be separated from the core pin.

[0004] However, during the process of pulling the core needle out of the mold, the length of the core needle exposed outside continues to increase. The exposed part of the core needle is easily impacted by external force during demolding, especially the tip of the core needle is prone to shaking, which makes the mold break very easily during demolding. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an injection mold for an optical fiber ceramic connector, which controls the movement of a damping ring through elastic action. During demolding, the damping ring and the mold move synchronously to protect the exposed part of the core needle and reduce damage to the core needle and the mold caused by collision or shaking.

[0010] Preferably, a shaping table is provided in the middle of the fixed template, a shaping hole is opened in the middle of the shaping table, two first channels are opened through the shaping table on the side close to the discharge hopper, and the two first channels are symmetrically distributed along the axis of the shaping table, and the end of the pressure rod close to the discharge hopper passes through the first channel and is close to the baffle, and each of the baffles is provided with a pressure groove on the side away from the discharge hopper, and the diameter of the pressure groove is greater than the diameter of the pressure rod.

[0016] Beneficial effects: The present invention provides an injection mold for optical fiber ceramic connectors. Compared with the prior art, it has the following beneficial effects: 1. When the core needle is pulled out of the mold, the exposed part of the core needle continues to increase, the vibration reduction ring is always pressed against the side of the mold away from the nozzle tube, and the vibration reduction ring moves along the axis of the molding hole to ensure that the movement direction of the vibration reduction ring itself will not tilt; under the elastic action of the spring, the vibration reduction ring moves synchronously with the mold to protect the exposed part of the core needle. At the moment when the core needle is just demolded from the mold, the tip of the core needle is very likely to vibrate slightly. At this time, the vibration reduction ring is used to seal the external environment of the core needle, reduce the vibration of the core needle, or even avoid the vibration of the core needle, reduce the damage caused by collision or shaking between the core needle and the mold, extend the service life of the core needle, and improve the product quality of the mold.

[0017] 2. The telescopic end of the telescopic part is inserted into the insertion hole with an insert plate to fix the vibration-damping ring. The bottom of the feed hopper is placed in the molding hole. The vibration-damping ring and the feed hopper are integrally formed. The upper part of the whole is fixed by the insert plate, and the bottom of the whole is fixed by the molding hole, thereby ensuring the fixation of the vibration-damping ring and the feed hopper as a whole.

[0018] 3. Since the material needs to enter the molding hole and cool before demolding, the screw first carries the connecting rod and the slider to squeeze the spring. At this time, the bottom end of the spring wants to push the vibration reduction ring into the molding hole under the action of elasticity, but the mold has not yet been formed, and the vibration reduction ring cannot be allowed to move at will. The vibration reduction ring needs to remain stationary. Therefore, by setting a small telescopic part, when the vibration reduction ring needs to be stationary, start the telescopic part and insert the plug plate into the socket. The vibration reduction ring is located between the plug plate and the round tube and cannot move. When demolding, the vibration reduction ring needs to move, and the plug plate can be pulled out of the socket in advance, and the vibration reduction ring can move synchronously with the mold.

[0019] 4. The damping ring is compatible with the core needle, so the diameter of the center hole of the damping ring needs to be the same as the diameter of the core needle, but the material also needs to flow from the damping ring into the molding hole. Therefore, when the core needle blocks the center hole, in order to ensure the flow of materials, the damping ring cannot have only the center hole, but also needs to add a discharge hole to ensure that the material enters the molding hole.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is described clearly and completely. Obviously, the described examples are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Reference Figure 1 - Fig.13 , an injection mold for an optical fiber ceramic connector, comprising:

[0040] The circular tube 31 has two third convex plates 38 connected to its inner wall. The third convex plates 38 are integrally formed with the circular tube 31 and form a tube body. A third channel 39 is penetrated through the side of the tube body close to the nozzle tube 14. A slide groove 36 is provided on the side of the tube body close to the nozzle tube 14. The two ends of the tube body are respectively connected to a first side plate 321 and a second side plate 351. Each slide groove 36 is connected to a third channel 39. A slider 371 is slidably connected in each third channel 39. Each slider 371 is connected to a baffle 374 through a slider 373. The slider 373 is slidably connected to the slide groove 36. The side of each slider 371 close to the nozzle tube 14 is connected to the screw 15 through a connecting rod 23.

[0041] During the mold molding process, the screw 15 is threadedly connected to the inner wall thread track of the sprinkler nozzle, and the screw 15 reciprocates along the axial direction of the sprinkler nozzle. When the screw 15 moves toward the direction close to the fixed mold plate 11, the screw 15 successively brings the connecting rod 23 and the slider 371 to move toward the fixed mold plate 11, the spring 372 is compressed, and the screw 15 squeezes the material of the sprinkler nozzle into the vibration reduction ring 41, the discharge hopper 45, and the molding hole 17 in turn. When the screw 15 moves toward the direction away from the fixed mold plate 11, the screw 15 successively brings the connecting rod 23 and the slider 371 to move toward the direction away from the fixed mold plate 11.

[0042] A damping ring 41, the side of the damping ring 41 close to the nozzle tube 14 is connected to the side of the spring 372 away from the nozzle tube 14, a center hole 42 is penetrated through the middle of the damping ring 41, a plurality of discharge holes 43 are penetrated through the side of the damping ring 41 close to the nozzle tube 14, each discharge hole 43 is located on the outside of the center hole 42, and each discharge hole 43 is connected to the center hole 42, a plug hole 44 is formed at the edge of the side of the damping ring 41 away from the nozzle tube 14, and the plug hole 44 is located between adjacent fan rings, and a discharge hopper 45 is connected to the bottom of the damping ring 41, and the discharge hopper 45 extends into the molding hole 17.

[0043] The core needle 16 is pulled out from the mold, and the length of the core needle 16 exposed outside increases continuously. The exposed part of the core needle 16 is easily impacted by external force during demolding, especially the tip of the core needle 16 is easy to shake. In order to reduce the vibration of the core needle 16 during demolding (especially the moment when the core needle 16 is separated from the material), a device that can match the core needle 16 and protect the exposed part of the core needle 16 from the outside is needed. The diameter of the core needle 16 is the same as the diameter of the central hole 42 in the middle of the vibration reduction ring 41. The vibration reduction ring 41 slides along the inner wall of the molding hole 17 and moves along the axis of the molding hole 17 to ensure that the molding hole 17 itself does not produce obvious vibration; through the elastic effect, the movement of the vibration reduction ring 41 is controlled. During demolding, the vibration reduction ring 41 moves with the movement of the material. The vibration reduction ring 41 always clings to the side of the mold close to the nozzle tube 14 to protect the exposed part of the core needle 16.

[0044] The damping ring 41 is matched with the core needle 16, so the diameter of the center hole 42 of the damping ring 41 needs to be the same as the diameter of the core needle 16, but the material also needs to flow from the damping ring 41 into the molding hole 17. Therefore, when the core needle 16 blocks the center hole 42, in order to ensure the flow of the material, the damping ring 41 cannot have only the center hole 42, but also needs to add a discharge hole 43 to ensure that the material enters the molding hole 17.

[0045] Usually, there are four molding holes 17 , and the amount of material flowing through all molding holes 17 per unit time is 1-1.5 times the amount of material flowing through the central hole 42 per unit time. The cross-sectional area and number of the molding holes 17 can also be set and adjusted according to actual manufacturing.

[0046] The plug board 46 is plugged into the plug hole 44 . A telescopic member 47 is connected to a side of the plug board 46 away from the plug hole 44 . The telescopic member 47 is used to drive the plug board 46 to enter and exit the plug hole 44 .

[0047] Since the material needs to enter the molding hole 17 and cool before demolding, the screw 15 first brings the connecting rod 23 and the slider 371 to squeeze the spring 372. At this time, the bottom end of the spring 372 wants to push the vibration reduction ring 41 into the molding hole 17 under the elastic action, but the mold has not yet been formed, and the vibration reduction ring 41 cannot be allowed to move at will. The vibration reduction ring 41 needs to remain stationary. Therefore, by setting a small telescopic member 47, when the vibration reduction ring 41 needs to be stationary, the telescopic member 47 is started and the plug plate 46 is inserted into the socket 44. The vibration reduction ring 41 is located between the plug plate 46 and the round tube 31 and cannot move. When the vibration reduction ring 41 needs to move during demolding, the plug plate 46 can be pulled out of the socket 44 in advance, and the vibration reduction ring 41 can move synchronously with the mold.

[0048] One end of the core needle 16 passes through the tube body, the center hole 42, the discharge hopper 45 in sequence and extends into the molding hole 17. The side of the movable template 13 close to the nozzle tube 14 is connected to a pressure rod 21. The screw 15 moves back and forth along the axis direction of the nozzle tube 14. The side of the screw 15 close to the circular tube 31 is connected to the slider 371 through the pressure rod 21.

[0049] A shaping table 12 is provided in the middle of the fixed template 11, and a shaping hole 17 is opened in the middle of the shaping table 12. Two first channels 22 are opened through the side of the shaping table 12 close to the discharge hopper 45, and the two first channels 22 are symmetrically distributed according to the axis of the shaping table 12. The end of the pressure rod 21 close to the discharge hopper 45 passes through the first channel 22 and is close to the baffle 374. A pressure groove 375 is opened on the side of each baffle 374 away from the discharge hopper 45, and the diameter of the pressure groove 375 is larger than the diameter of the pressure rod 21.

[0050] The diameter of the discharge hopper 45 on the side close to the nozzle tube 14 is larger than the diameter of the discharge hopper 45 away from the discharge hopper 45 , the diameter of the shaping hole 17 is equal to the diameter of the discharge hopper 45 on the side close to the discharge hopper 45 , and the diameter of the discharge hopper 45 away from the discharge hopper 45 is larger than the diameter of the core needle 16 .

[0051] Two first convex plates 322 are connected to the inner wall of the first side plate 321, and each first convex plate 322 is connected to a first sealing sheet 33 on a side close to the discharge hopper 45, and each first convex plate 322 is connected to a second sealing sheet 34 on a side away from the discharge hopper 45. The second sealing sheet 34 is located in the third channel 39. The first sealing sheet 33, the second sealing sheet 34, and the first convex plate 322 constitute a sealing plate, and a sliding hole 323 is penetrated through the side of the sealing plate away from the discharge hopper 45. The side of the connecting rod 23 close to the molding table 12 passes through the sliding hole 323 and is connected to the slider 371. Two second convex plates 352 are connected to the inner wall of the second side plate 351. The two second convex plates 352 are equidistantly distributed in the circumferential direction of the inner wall of the second side plate 351. The second convex plates 352 and the second side plate 351 constitute a side plate, and a second channel 353 is penetrated through the side of the side plate close to the nozzle pipe 14, and the second channel 353 is connected to the third channel 39.

[0052] The outer edge of the vibration reduction ring 41 close to the nozzle pipe 14 is made of rubber material, and the side of the second side plate 351 away from the nozzle pipe 14 is made of rubber material. The vibration reduction ring 41 is slidably connected to the molding hole 17.

[0053] When the vibration damping ring 41 is pressed against the second side plate 351 , the vibration damping ring 41 is in the starting position. When the vibration damping ring 41 moves to the end of the molding hole 17 away from the nozzle tube 14 , the vibration damping ring 41 is in the ending position.

[0054] Two lifting plates can be set on the side of the vibration reduction ring 41. The two lifting plates are equidistantly distributed in the circumferential direction of the vibration reduction ring 41. The pressure rod 21 can move with the movable template 13 to squeeze the lifting plates, thereby driving the vibration reduction ring 41 close to the nozzle tube 14, so as to assist the vibration reduction ring 41 to return to its original position.

[0055] The discharge hole 43 is fan-shaped in a top view, and the arc length of the fan-shaped side away from the axis of the vibration reduction ring 41 is greater than the arc length of the fan-shaped side close to the axis of the vibration reduction ring 41.

[0056] The tip of a sector is truncated, that is, the vertex corresponding to the central angle is removed, and the remaining part forms a sector ring. A sector is a figure surrounded by the central angle and the arc corresponding to it, while a sector ring is a part of the annular area surrounded by two concentric arcs of different radii and the two radii connecting the two arcs.

[0057] When in use, the telescopic member 47 is started, and the telescopic end of the telescopic member 47 is inserted into the insertion hole 44 with the plug plate 46, so that the vibration reduction ring 41 is fixed, and the bottom of the feed hopper is placed in the molding hole 17. The vibration reduction ring 41 and the feed hopper are integrally formed, and the upper part of the whole is fixed by the plug plate 46, and the bottom of the whole is fixed by the molding hole 17, thereby ensuring that the vibration reduction ring 41 and the feed hopper are fixed as a whole.

[0058] Under the condition that the central axis of the circular tube 31 is collinear with the central axis of the molding hole 17, the second side plate 351 at one end of the circular tube 31 is in contact with the vibration reduction ring 41. The outer edge of the vibration reduction ring close to the nozzle tube 14 is made of rubber material, and the sides of the two side plates away from the nozzle tube 14 are both made of rubber material. The rubber at one end of the circular tube 31 and the rubber of the second side plate 351 are squeezed against each other to form a sealing strip, thereby ensuring that there is no material leakage at the joint between the circular tube 31 and the second side plate 351.

[0059] Injection molding begins, the screw 15 moves along the axis of the nozzle tube 14, and the screw 15 moves in turn with the connecting rod 23, the slider 371, the slide plate 373, and the core needle 16 toward the molding table 12. The spring 372 is compressed, and the material in the nozzle tube 14 enters the molding hole 17 through the circular tube 31, the discharge hole 43, and the discharge hopper 45, and the material is cooled and formed in the molding hole 17.

[0060] Prepare to demould, close the telescopic member 47, and pull the telescopic end of the telescopic member 47 out of the insertion hole 44 with the plug plate 46. The plug plate 46 no longer restricts the vibration reduction ring 41. Due to the loss of the obstruction of the plug plate 46, the vibration reduction ring 41 is pressed against the mold under the elastic action of the spring 372. When the movable platen 13 separates from the fixed platen 11 with the mold, the mold moves in the direction away from the nozzle tube 14, the core needle 16 is pulled out of the mold, the exposed part of the core needle 16 increases continuously, and the damping ring 41 moves together with the mold. The damping ring 41 is always pressed tightly against the side of the mold away from the nozzle tube 14, the diameter of the core needle 16 is the same as the diameter of the center hole 42 in the middle of the damping ring 41, the damping ring 41 slides along the inner wall of the molding hole 17, and the damping ring 41 moves along the axis of the molding hole 17 to ensure that the moving direction of the damping ring 41 itself will not be tilted; under the elastic action of the spring 372, the damping ring 41 moves synchronously with the mold, and the damping ring 41 is always close to the side of the mold close to the nozzle tube 14 to protect the exposed part of the core needle 16. At the moment when the core needle 16 is just released from the mold, the tip of the core needle 16 is very likely to vibrate slightly. At this time, the external environment of the core needle 16 is sealed by the vibration reduction ring 41 to reduce or even avoid the vibration of the core needle 16, thereby reducing the damage between the core needle 16 and the mold caused by collision or shaking, extending the service life of the core needle 16, and improving the product quality of the mold.

[0061] After demoulding is completed, the screw 15 moves with the core needle 16 toward the direction close to the nozzle tube 14. When the screw 15 stops moving, the core needle 16 and the vibration reduction ring 41 need to move to the initial position, the telescopic member 47 is started, and the plug plate 46 is inserted into the plug hole 44.

[0062] Two lifting plates can be set on the side of the vibration reduction ring 41. The two lifting plates are equidistantly distributed in the circumferential direction of the vibration reduction ring 41. The pressure rod 21 can move with the movable template 13 to squeeze the lifting plates, thereby driving the vibration reduction ring 41 close to the nozzle tube 14, so as to assist the vibration reduction ring 41 to return to its original position.
