Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to endoscope tip injection molds. Background Technology

[0002] An endoscope consists of a control handle, an insertion tube, and a tip, connected in sequence. The insertion tube can enter the stomach through the mouth or other natural orifices. To minimize patient discomfort during the procedure, endoscopic products should minimize the size of the tip while ensuring adequate instrument access.

[0003] The tip includes a tip assembly and a tip housing. In related technologies, a thin tip housing is generally manufactured first, and then the tip assembly is inserted and fixed inside the tip housing.

[0004] However, due to the small wall thickness of the front shell, it is difficult to control during production, and uneven glue application or cold gel marks are likely to occur. As a result, the finished product cannot be guaranteed to pass the electrical performance test. Utility Model Content

[0005] Therefore, it is necessary to provide an endoscope tip injection mold to address the problems of uneven glue application or cold gel marks that easily occur during the production of thin-walled tip shells.

[0006] An endoscope tip injection mold, the endoscope tip injection mold comprising:

[0007] The lower mold assembly has a receiving groove extending in a first direction;

[0008] An upper mold assembly has a through hole extending in a first direction. The upper mold assembly is movable relative to the lower mold assembly in the first direction so that the through hole communicates with the receiving groove to form a glue injection cavity. The glue injection cavity is used to house the tip assembly, and the cavity wall of the glue injection cavity has a glue injection hole for injecting glue into the glue injection cavity.

[0009] In one embodiment, the upper mold assembly includes a first mold base and a second mold base disposed opposite to each other along a second direction. A portion of the through hole is formed on the first mold base, and another portion of the through hole is formed on the second mold base. The through hole is formed when the first mold base and the second mold base are closed.

[0010] In one embodiment, a first mold core is provided on the first mold base, and a second mold core is provided on the second mold base. A portion of the through holes are formed on the first mold core, and another portion of the through holes are formed on the second mold core.

[0011] The first mold core and the second mold core are capable of elastic deformation. The surface of the first mold core that mates with the second mold core extends out of the first mold base, and the surface of the second mold core that mates with the first mold core extends out of the second mold base.

[0012] In one embodiment, the first mold base and the second mold base are respectively connected to a power mechanism;

[0013] The endoscope tip injection mold includes a frame, on which a position sensor is mounted. The power mechanism is signal-connected to the position sensor and is used to control the first mold base and the second mold base to close according to the signal detected by the position sensor.

[0014] In one embodiment, the lower mold assembly includes a lower mold base, on which a lower mold core is disposed, and the receiving groove is formed on the lower mold core, which is capable of elastic deformation.

[0015] In one embodiment, the surface of the lower mold core that mates with the first mold core and the second mold core protrudes from the lower mold base;

[0016] And / or, the surface of the first mold core that mates with the lower mold core protrudes beyond the first mold base, and the surface of the second mold core that mates with the lower mold core protrudes beyond the second mold base.

[0017] In one embodiment, the injection holes are respectively opened on the two opposite sides of the lower mold core, and each injection hole is connected to the receiving groove.

[0018] In one embodiment, a curing lamp is provided on the lower mold assembly, the curing lamp being used to irradiate the adhesive in the injection cavity through the lower mold core.

[0019] In one embodiment, the injection mold includes a wire clamp disposed on the side of the upper mold assembly away from the lower mold assembly, the wire clamp being used to clamp a tube and / or wire connected to the tip assembly.

[0020] In one embodiment, the wire clamp includes a clamping base and a clamping cover. The clamping base has a through hole, and the clamping cover is rotatably connected to the clamping base so as to cover the through hole. The through hole is used to pass through the tube and / or wire.

[0021] In the aforementioned endoscope tip injection mold, when the lower mold assembly and the upper mold assembly move closer together along the first direction so that the through hole connects with the receiving groove, an injection cavity is formed. The tip assembly is located inside the injection cavity. At this time, glue is injected into the injection cavity through the injection hole, which fills the gap between the injection cavity and the tip assembly. After the glue cures, a thin-walled tip shell can be directly formed on the outside of the tip assembly. Moreover, the thin-walled tip shell formed by the endoscope tip injection mold of this application will not have uneven glue flow or cold gel marks, has excellent electrical performance, and the tip assembly has good stability. In addition, during demolding, the lower mold assembly and the upper mold assembly move apart along the first direction, which exposes the tip portion of the endoscope, making it easy to demold the entire endoscope tip through the exposed portion.

[0040] See Figures 1-5 An embodiment of this application provides an endoscope tip injection mold, which includes a lower mold assembly 200 and an upper mold assembly 100. The lower mold assembly 200 has a receiving groove extending along a first direction, and the upper mold assembly 100 has a through hole extending along the first direction. The upper mold assembly 100 is movable relative to the lower mold assembly 200 along the first direction, so that the through hole communicates with the receiving groove to form an injection cavity 230. The injection cavity 230 is used to house the tip assembly 20, and the cavity wall of the injection cavity 230 has an injection hole for injecting glue into the injection cavity 230.

[0041] In this embodiment, when the lower mold assembly 200 and the upper mold assembly 100 move closer to each other along the first direction, so that the through hole communicates with the receiving groove, a glue injection cavity 230 is formed. The tip assembly 20 is located inside the glue injection cavity 230. At this time, glue is injected into the glue injection cavity 230 through the glue injection hole, so that the glue fills the gap between the glue injection cavity 230 and the tip assembly 20. After the glue cures, a thin-walled tip shell can be directly formed on the outside of the tip assembly 20. Moreover, the thin-walled tip shell formed by the endoscope tip glue injection mold of this application will not have uneven glue flow or cold gel marks, has excellent electrical performance, and the tip assembly 20 has good stability. In addition, during demolding, the lower mold assembly 200 and the upper mold assembly 100 move apart along the first direction, so that the tip part of the endoscope is exposed, which facilitates the demolding of the entire endoscope tip through the exposed part.

[0042] In some embodiments, the upper mold assembly 100 includes a first mold base 110 and a second mold base 120 disposed opposite to each other along a second direction. A portion of the first mold base 110 has a through hole, and another portion of the second mold base 120 has a through hole. When the first mold base 110 and the second mold base 120 are closed, a through hole is formed.

[0043] In this embodiment, during production, the endoscope's tip assembly 20 is first inserted into the receiving groove, and the tube and / or wire 10 connected to the tip assembly 20 are fixed. The first mold base 110 and the second mold base 120 are respectively located on both sides of the tube and / or wire 10 along the second direction. During glue injection, the first mold base 110 and the second mold base 120 firstly move towards the lower mold assembly 200 along the first direction, and then move towards the tube and / or wire 10 along the second direction at a preset position. Finally, they move towards the lower mold assembly 200 again along the first direction, so that the receiving groove and the through hole are connected to form the glue injection cavity 230. After the glue injection is completed and the glue has cured, the first mold base 110 and the second mold base 120 are first moved along the first direction to return to the preset position. Then, the first mold base 110 and the second mold base 120 are moved apart along the second direction to detach from the tip housing. Finally, they move simultaneously along the first direction to return to the initial position. For example, the first direction is the vertical direction, and the second direction is the horizontal direction.

[0044] In this application, the upper mold assembly 100 includes a first mold base 110 and a second mold base 120 disposed opposite to each other along a second direction. During demolding, the first mold base 110 and the second mold base 120 can move apart along the second direction respectively, so as to facilitate the rapid demolding of the upper part of the endoscope tip. After the upper part of the endoscope tip is demolded, it is convenient to clamp the upper part of the endoscope tip, so as to demold the lower part of the endoscope tip.

[0045] Furthermore, a first mold core 130 is provided on the first mold base 110, and a second mold core 140 is provided on the second mold base 120. The first mold core 130 has a portion of through holes, and the second mold core 140 has another portion of through holes. The first mold core 130 and the second mold core 140 are capable of elastic deformation. The surface of the first mold core 130 that mates with the second mold core 140 extends out of the first mold base 110, and the surface of the second mold core 140 that mates with the first mold core 130 extends out of the second mold base 120.

[0046] Specifically, the first mold core 130 and the second mold core 140 can be made of silicone or rubber so that the first mold core 130 and the second mold core 140 can undergo elastic deformation.

[0047] The surface of the first mold core 130 that mates with the second mold core 140 extends out of the first mold base 110, and the surface of the second mold core 140 that mates with the first mold core 130 extends out of the second mold base 120. That is, when the first mold base 110 and the second mold base 120 simultaneously drive the first mold core 130 and the second mold core 140 to move along the second direction toward the tube and / or wire 10, so that the first mold base 110 and the second mold base 120 abut against each other to close the mold, the first mold core 130 and the second mold core 140 can be tightly squeezed, thereby preventing glue leakage.

[0048] Of course, the first mold base 110 and the second mold base 120 are made of hard materials to ensure that when the first mold base 110 and the second mold base 120 are closed, they will not deform or the amount of deformation will be small.

[0049] In some embodiments, the first mold base 110 and the second mold base 120 are respectively connected to the power mechanism 160; the endoscope tip injection mold includes a frame 300, on which a position sensor is provided, and the power mechanism 160 is signal-connected to the position sensor. The power mechanism 160 is used to control the first mold base 110 and the second mold base 120 to close the mold according to the signal detected by the position sensor.

[0050] In this embodiment, the position sensor can be a photoelectric switch, an infrared position sensor, or an acoustic position sensor. The lower mold assembly 200 is fixed on the frame 300, and the upper mold assembly 100 can move along a first direction on the frame 300 to approach or move away from the lower mold assembly 200. When the upper mold assembly 100 moves downward to a preset position, the position sensor detects a signal and transmits the signal to the power mechanism 160. The power mechanism 160 drives the first mold base 110 and the second mold base 120 to move towards the center respectively, so that the first mold core 130 and the second mold core 140 close the mold. After closing the mold, the entire upper mold assembly 100 continues to move downward to close the mold with the lower mold assembly 200.

[0051] Specifically, the upper mold assembly 100 also includes an upper mold base plate 170 and a lifting mechanism. The first mold base 110 and the second mold base 120 are respectively disposed on the upper mold base plate 170. The upper mold base plate 170 is connected to the lifting mechanism, which is used to drive the upper mold base plate 170 to move along the first direction.

[0052] The upper mold base plate 170 has a mounting hole, and a guide rod extending in the second direction is provided in the mounting hole. The guide rod passes through the first mold base 110 and the second mold base 120, so that the first mold base 110 and the second mold base 120 are movably disposed in the mounting hole in the second direction. The power mechanism 160 can be a cylinder, a linear module, etc. The power mechanism 160 is disposed on the upper mold base plate 170, and the first mold base 110 and the second mold base 120 are respectively connected to the corresponding power mechanism 160.

[0053] In other embodiments, the upper mold assembly 100 may be fixed to the frame 300, and the lower mold assembly 200 may move along the first direction to the upper mold assembly 100. Alternatively, both the upper mold assembly 100 and the lower mold assembly 200 may be movable along the first direction.

[0054] In some embodiments, the lower mold assembly 200 includes a lower mold base 210, a lower mold core 220 is provided on the lower mold base 210, a receiving groove is formed on the lower mold core 220, and the lower mold core 220 is capable of elastic deformation.

[0055] In this embodiment, the lower mold core 220 can also undergo elastic deformation, so that when it is molded with the upper mold core (first mold core 130 and second mold core 140), the upper mold core and the lower mold core 220 can fit tightly together to prevent glue leakage.

[0056] Specifically, the lower mold core 220 is provided with a positioning structure for cooperating with the tip assembly 20 to position the tip assembly 20. The positioning structure may be a protrusion that cooperates with the tube and / or wire 10 on the tip assembly 20 to position the tip assembly 20.

[0057] Furthermore, the surface of the lower mold core 220 that mates with the first mold core 130 and the second mold core 140 protrudes from the lower mold base 210; and / or, the surface of the first mold core 130 that mates with the lower mold core 220 protrudes outside the first mold base 110, and the surface of the second mold core 140 that mates with the lower mold core 220 protrudes outside the second mold base 120.

[0058] In some embodiments, the surface of the lower mold core 220 that mates with the first mold core 130 and the second mold core 140 protrudes from the lower mold base 210. The surface of the first mold core 130 that mates with the lower mold core 220 is flush with the surface of the first mold base 110. The surface of the second mold core 140 that mates with the lower mold core 220 is flush with the surface of the second mold base 120. When the upper mold assembly 100 and the lower mold assembly 200 are closed, the lower mold core 220 can simultaneously press the upper first mold core 130 and the second mold core 140 so that the three fit together tightly.

[0059] In other embodiments, the surface of the first mold core 130 that mates with the lower mold core 220 protrudes beyond the first mold base 110, the surface of the second mold core 140 that mates with the lower mold core 220 protrudes beyond the second mold base 120, and the surface of the lower mold core 220 that mates with the first mold core 130 and the second mold core 140 is flush with the surface of the lower mold base 210. When the upper mold assembly 100 and the lower mold assembly 200 are closed, the first mold core 130 and the second mold core 140 can simultaneously press the lower mold core 220, so that the three fit together tightly.

[0060] In other embodiments, the surface of the lower mold core 220 that mates with the first mold core 130 and the second mold core 140 protrudes beyond the lower mold base 210; the surface of the first mold core 130 that mates with the lower mold core 220 protrudes beyond the first mold base 110, and the surface of the second mold core 140 that mates with the lower mold core 220 protrudes beyond the second mold base 120. When the upper mold assembly 100 and the lower mold assembly 200 are closed, the first mold core 130 and the second mold core 140 press against the lower mold core 220 to ensure a tight fit between the three components.

[0061] In some embodiments, injection holes are provided on opposite sides of the lower mold core 220, and each injection hole is connected to a receiving groove.

[0062] In this embodiment, the injection hole is located on the lower mold core 220. During injection, the adhesive needs to overcome gravity and move upwards, which helps to fill the entire gap. Injection holes are provided on opposite sides of the lower mold core 220 to allow adhesive to be injected simultaneously from both sides of the lower mold core 220, increasing the injection rate and ensuring uniform distribution of the adhesive.

[0063] It should be noted that the glue injection module also includes a glue injection component 600. The glue injection nozzle of the glue injection component 600 is used to extend into the glue injection hole to inject glue into the glue injection cavity 230, and at the same time, it is used to seal the glue injection hole.

[0064] In some embodiments, a curing lamp 500 is provided on the lower mold assembly 200, and the curing lamp 500 is used to irradiate the adhesive in the injection cavity 230 through the lower mold core 220.

[0065] In this embodiment, the lower mold core 220 is made of transparent material. After the glue is injected, the curing lamp 500 is used to irradiate the glue in the glue injection cavity 230 through the lower mold core 220, thereby causing the glue to cure.

[0066] In some embodiments, the endoscope tip injection mold includes a wire clamp 400, which is disposed on the side of the upper mold assembly 100 away from the lower mold assembly 200, and is used to clamp the tube and / or wire 10 connected to the tip assembly 20.

[0067] In this embodiment, the tube and / or wire 10 connected to the tip assembly 20 serve as an instrument channel and for signal transmission. The wire clamp 400 is used to clamp the tube and / or wire 10 connected to the tip assembly 20 to ensure the accuracy of the tip assembly 20's position and prevent the tip assembly 20 from shifting within the glue injection cavity 230.

[0068] Furthermore, the wire clamp 400 includes a clamping seat 410 and a clamping cover 420. The clamping seat 410 has a through hole, and the clamping cover 420 is rotatably connected to the clamping seat 410 so as to cover the through hole. The through hole is used to pass through the tube and / or wire 10.

[0069] One end of the clamping cover 420 is rotatably connected to the clamping seat 410, and the clamping seat 410 is provided with a magnetic attraction element for adsorbing the clamping cover 420 so that the clamping cover 420 closes on the through hole.

[0070] Of course, the clamping cover 420 can also be detachably connected to the clamping seat 410 so that the clamping cover 420 closes on the through hole.

[0071] An embodiment of this application also provides a method for controlling an endoscope tip injection mold, the method comprising:

[0072] The tip component 20 is disposed within the receiving groove;

[0073] The upper mold assembly 100 and the lower mold assembly 200 move closer to each other along the first direction so that the upper mold assembly 100 and the lower mold assembly 200 are closed, and the through hole communicates with the receiving groove to form the injection cavity 230.

[0074] Glue is injected into the injection cavity 230 and cured, and the glue forms an end shell outside the end component 20;

[0075] The upper mold assembly 100 and the lower mold assembly 200 move apart along a first direction to allow the endoscope tip to be demolded.

[0076] In this embodiment, when the lower mold assembly 200 and the upper mold assembly 100 move closer to each other along the first direction, so that the through hole communicates with the receiving groove, a glue injection cavity 230 is formed. The tip assembly 20 is located inside the glue injection cavity 230. At this time, glue is injected into the glue injection cavity 230 through the glue injection hole, so that the glue fills the gap between the glue injection cavity 230 and the tip assembly 20. After the glue cures, a thin-walled tip shell can be directly formed on the outside of the tip assembly 20. Moreover, the thin-walled tip shell formed by the endoscope tip glue injection mold of this application will not have uneven glue flow or cold gel marks, has excellent electrical performance, and the tip assembly 20 has good stability. During demolding, the lower mold assembly 200 and the upper mold assembly 100 move apart along the first direction, so that the tip part of the endoscope is exposed, making it easy to demold the entire endoscope tip through the exposed part.

[0077] In some embodiments, the upper mold assembly 100 includes a first mold base 110 and a second mold base 120 disposed opposite to each other along a second direction. The first mold base 110 has a portion of through holes, and the second mold base 120 has another portion of through holes.

[0078] In this process, the upper mold assembly 100 and the lower mold assembly 200 move closer to each other along a first direction, so that the upper mold assembly 100 and the lower mold assembly 200 are closed together. The through hole communicates with the receiving groove to form the injection cavity 230. The specific steps include:

[0079] The first mold base 110 and the second mold base 120 approach the lower mold assembly 200 along the first direction. At a preset position, the first mold base 110 and the second mold base 120 move along the second direction to close together and form a through hole. The first mold base 110 and the second mold base 120 approach the lower mold assembly 200 again along the first direction so that the receiving groove and the through hole are connected to form the injection cavity 230.

[0080] The upper mold assembly 100 and the lower mold assembly 200 move and separate from each other along a first direction to allow the endoscope tip to be demolded. Specific steps include:

[0081] The first mold base 110 and the second mold base 120 move away from the lower mold assembly 200 along the first direction to return to the preset position. The first mold base 110 and the second mold base 120 move separately along the second direction to detach from the tip shell. The first mold base 110 and the second mold base 120 move back to the initial position along the first direction to demold the endoscope tip.

[0082] When the mold is closed, the first mold base 110 and the second mold base 120 move downwards to a preset position simultaneously. Then, the first mold base 110 and the second mold base 120 move towards the middle simultaneously until the first mold base 110 and the second mold base 120 close the mold. That is, the first mold base 110 and the second mold base 120 move downwards first and then move towards the middle. This is to prevent the first mold base 110 and the second mold base 120 from rubbing against the tube body and / or wire 10 and damaging the tube body and / or wire 10 when they move downwards directly after the mold is closed. Or, the first mold base 110 and the second mold base 120 may affect the positioning of the lower mold core 220 on the tube body and / or wire 10 after the mold is closed, causing the position of the tip component 20 in the injection cavity 230 to shift. In this application, the first mold base 110 and the second mold base 120 first move downward to a preset position, and then move towards the middle. The distance between the preset position and the upper surface of the lower mold assembly 200 in the vertical direction is 3mm-10mm. When the first mold base 110 and the second mold base 120 move downward to the preset position, they are close to the position of the lower mold core 220 that positions the tip assembly 20. The position of the tip assembly 20 is relatively fixed. At this time, the first mold base 110 and the second mold base 120 close the mold, which can avoid friction with the tip assembly 20 and reduce the impact on the position of the tip assembly 20.

[0083] During demolding, the first mold base 110 and the second mold base 120 move upward to a preset position at the same time, and then move along the second direction to separate from each other. This is to prevent the first mold core 130 and the second mold core 140 from rubbing against the lower mold core 220 when the first mold base 110 and the second mold base 120 are directly separated on the lower mold assembly 200, thereby preventing damage to the first mold core 130 and the second mold core 140.

[0084] The initial position is the position of the first mold base 110 and the second mold base 120 when the mold is closed.
