[0002] Medical devices themselves have strict precision properties. Therefore, more precise technical requirements are also put forward for the production and matching of medical device parts. In the process of producing and matching medical parts, there is no room for any flaws in the surface quality, precision, and hygiene of injection molded products, from large hyperbaric oxygen chambers to small hearing aids, anesthesia laryngoscopes, medical buttons, etc.

[0003] Medical disposable anesthesia pharyngoscope is relatively complex and the most typical among many medical injection molding products. First, the product structure is complex and the top space is narrow. Second, the top tip contacts the skin inside the body, and the material hygiene requirements are strict. Third, the size and quality requirements are strict, and surface defects are not allowed. Fourth, injection molding product pharyngoscopes are generally disposable products, with large quantities and price costs under control.

[0004] In the current existing technology, visual laryngoscopes are produced by injection molding. The molds of visual laryngoscopes are generally fixed in style, and only the same model of products can be produced each time. The size of the visual laryngoscope cannot be changed, resulting in a single product size that cannot adapt to diverse needs.

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] Example: A visual laryngoscope mold, such as Figure 1-4As shown, it includes a lower mold table 100 and an upper mold table 200, the upper mold table 200 is located directly above the lower mold table 100, the lower mold table 100 is externally connected to an injection molding machine, and the upper mold table 200 is externally connected to a telescopic drive device. The lower mold table 100 is used to inject molten plastic into the injection space, and the upper mold table 200 is used to merge with the lower mold table 100 to form a closed space for convenient injection molding. The top surface of the lower mold table 100 is provided with a shaping mold 101, and the shaping mold 101 includes two baffles; the upper mold table 200 is internally provided with an adjustment component for adjusting the size of the visualized laryngoscope mold, and the adjustment component includes an arc-shaped sealing plate 201 that performs a circular motion with the upper mold table 200 as a base surface and a vertical sealing plate 202 that moves up and down with the upper mold table 200 as a base surface, and one side of the arc-shaped sealing plate 201 and the vertical sealing plate 202 Both are provided with folding plates. When the upper mold table 200 moves toward the lower mold table 100, the adjusting assembly and the shaping mold 101 form an injection molding space for the injection molding of the visual laryngoscope. When the upper mold table 200 moves down onto the lower mold table 100, the two baffles of the shaping mold 101 and the folding plates on the arc-shaped sealing plate 201, the folding plates on the vertical sealing plate 202, and the table tops of the upper mold table 200 and the lower mold table 100 form a closed space, i.e., an injection molding space. At this time, molten plastic can be injected into the space to produce the visual laryngoscope. In addition, the length of the vertical section of the visual laryngoscope can be adjusted by the vertical sealing plate 202 that moves up and down, and the length of the arc section of the visual laryngoscope can be adjusted by the arc-shaped sealing plate 201 that can make a circular motion, so that the visual laryngoscope mold has the function of adjustable size, thereby improving the practicality of the device. The solution for the vertical sealing plate 202 to move up and down on the table surface of the upper mold table 200 is as follows: A limiting cylinder 205 is arranged on the back of the vertical sealing plate 202, and the inner wall of the limiting cylinder 205 is slidably connected to a limiting rod 206, one end of the limiting rod 206 is connected to a first rotating rod 203 via a rotating shaft, and one end of the first rotating rod 203 is fixedly connected to a supporting rod 208; the rotation of the supporting rod 208 drives the first rotating rod 203 to rotate, so that the limiting rod 206 moves in the limiting cylinder 205, and then causes the vertical sealing plate 202 fixedly connected to the limiting cylinder 205 to move up and down on the upper mold table 200; The scheme for the arc-shaped sealing plate 201 to rotate on the table surface of the upper mold table 200 is as follows: A second rotating rod 204 is disposed on the back of the arc-shaped sealing plate 201, and one end of the second rotating rod 204 is sleeved on the outer wall of the support rod 208; the second rotating rod 204 rotates around the central axis of the support rod 208, thereby driving the arc-shaped sealing plate 201 to make a circular motion on the table surface of the upper mold table 200; In order to increase or decrease the length of the vertical section and the length of the arc section of the visualization laryngoscope in proportion to each other, the adjustment component also includes a driving gear 207 of an externally connected rotational drive device, and the driving gear 207 is respectively meshed with the gear on the second rotating rod 204 and the gear on the supporting rod 208. When the driving gear 207 rotates, the first rotating rod 203 and the second rotating rod 204 make circular motions in opposite directions. The rotation of the driving gear 207 causes the gears meshing therewith to rotate, thereby causing the first rotating rod 203 and the second rotating rod 204 to rotate. When the first rotating rod 203 rotates clockwise, the second rotating rod 204 rotates counterclockwise. When the first rotating rod 203 rotates counterclockwise, the second rotating rod 204 rotates clockwise, and the first rotating rod 203 and the second rotating rod 204 rotate at the same angle, such as Figure 8 As shown, when the angle between the first rotating rod 203 and the reference line is θ, the length H of the vertical segment in the injection molding space is expressed as: Wherein, L1 is the length of the first rotating rod 203, C1 is the distance from the folded plate on the vertical sealing plate 202 to the middle of the limiting cylinder 205, At the same time, the length R of the arc segment in the injection molding space (the arc length of the arc segment is formed with the central axis of the support rod 208 as the center and the length of the second rotating rod 204 as the radius) is expressed as: Wherein, L2 is the length of the second rotating rod 204, C2 is the arc corresponding to the angle between the first rotating rod 203 and the reference line in the initial state, C3 is the arc length between the reference line and the folded plate on the arc-shaped sealing plate 201 in the initial state (with the central axis of the support rod 208 as the center and the length of the second rotating rod 204 as the radius), In summary, the relationship between the length of the vertical segment and the length of the arc segment in the injection space is: Wherein, H is the length of the vertical segment in the injection molding space, L1 is the length of the first rotating rod 203, R is the length of the arc segment in the injection molding space with the central axis of the support rod 208 as the center and the second rotating rod 204 as the radius, L2 is the length of the second rotating rod, and C1, C2, and C3 are constants; The two baffles include a vertical section and an arc section, the vertical sections of the two baffles are parallel to each other, and the arc sections of the two baffles have the same center (such as Figure 8As shown in the figure, the center of the circle is the central axis of the support rod 208), the junction of the vertical segments and the arc segments of the two baffles is the reference line, the reference line is used as the starting point of the vertical segment and the arc segment, the starting points of the vertical segments of the two baffles are located on the same horizontal line, and the ending points of the vertical segments of the two baffles are also located on the same horizontal line, the starting points of the arc segments of the two baffles are located on the same horizontal line, and the ending points of the arc segments of the two baffles are located on a chord with the support rod 208 as the center of the circle, and the angle of the chord with the reference line as the starting line is 180-250°, the starting points and ending points of the two baffles are all located on the same straight line, ensuring that the distance between the two baffles is equal, and there is no gap when matched with the folded plates on the vertical sealing plate 202 and the arc sealing plate 201, thereby improving the practicality of the device; An injection port 102 is provided on the top surface of the lower mold table 100. The injection port 102 is located between the two baffles of the molding mold 101 and on the side of the arc section of the baffle close to the vertical section. The injection port 102 is located below the reference line and in the middle of the two baffles. No matter how the vertical section and the arc section of the injection space change, the injection port 102 is always located inside the injection space.

[0029] When this embodiment is used,.

[0030] A traveling waterway of a visual laryngoscope mold comprises the above-mentioned visual laryngoscope mold, wherein the lower mold platform 100 and the upper mold platform 200 are both provided with water tanks, and the top surface of the lower mold platform 100 is provided with a water baffle 103, the water baffle 103 is in the shape of a fence, and the shaping mold 101 and the recovery pipe 110 are wrapped therein, and the water baffle 103 at the recovery pipe 110 is in an arc shape, compared with the right angle shape, so that when the water flows into the recovery pipe 110, the collision of the water flow is avoided, thereby avoiding the splashing of the water flow, and a cooling space is formed between the water baffle 103 and the injection space; the cooling space is used for absorbing heat from the molten plastic in the injection space after the cooling water enters therein, thereby accelerating the cooling and shaping speed thereof, The bottom surface of the upper mold platform 200 is provided with a water discharge pipe 210 for injecting cooling water required for injection molding. The specific scheme about the water discharge pipe 210 is as follows: The drain pipe 210 is processed with multiple drain ports 215 around it; multiple drain telescopic rods 216 are fixedly connected to the inner wall at the bottom end of the drain pipe 210, and a drain plug 212 is provided at the telescopic end of the drain telescopic rod 216. The outer wall at the bottom end of the drain plug 212 is fixedly connected to a push-in support rod 214. The water tank of the upper mold platform 200 is connected to the recovery pipe 110. In the initial state, the drain telescopic rod 216 is squeezed and compressed by the drain plug 212. The drain plug 212 is located in the inner wall of the drain pipe 210, blocking the drain pipe 210, and the water in the water tank of the upper mold platform 200 cannot flow out from the drain port 215 through the drain pipe; The top surface of the lower mold table 100 is provided with a recovery pipe 110 for recovering cooling water after injection molding. The specific scheme for the recovery pipe 110 is as follows: The recovery pipe 110 is processed with a plurality of recovery ports 115 around it; a cross support frame 114 is fixedly connected to the inner wall of the bottom end of the recovery pipe 110, a recovery telescopic rod 111 is fixedly connected to the top of the cross support frame 114, a recovery plug 112 is fixedly connected to the telescopic end of the recovery telescopic rod 111, and a ejection support rod 113 is fixedly connected to the top of the recovery plug 112; in the initial state, the recovery telescopic rod 111 is in a naturally extended state, at which time the recovery plug 112 is located inside the recovery pipe 110, and the bottom surface height of the recovery plug 112 is higher than the top height of the recovery port 115, but at this time, there is no cooling water in the cooling space; The central axis of the drain pipe 210 and the recovery pipe 110 is the same, and a groove is arranged inside the push-in support rod 214. The inner diameter of the groove of the push-in support rod 214 is the same as the outer diameter of the ejection support rod 113. When in use, the upper mold table 200 moves downward and moves to the lower mold table 100. The ejection support rod 113 enters the inner groove of the push-in support rod 214 and squeezes the push-in support rod 214. At this time, the drain plug 212 and The gravity of the push rod 214 and the gravity of the recovery plug 112 and the ejection support rod 113 are greater than the elastic force of the recovery telescopic rod 111, that is, the recovery telescopic rod 111 contracts first, and the recovery plug 112 blocks the recovery port 115 of the recovery pipe 110. As the upper mold table 200 continues to move downward, the recovery plug 112 and the ejection support rod 113 squeeze the drain plug 212, so that the drain plug 212 moves upward, that is, it is separated from the drain pipe 210. At this time, the cold The cooling water enters through the gap between the drain plug 212 and the drain pipe 210, and flows into the cooling space through the drain port 215 to cool the injection molding process. When the injection molding is completed, the upper mold platform 200 moves upward and separates from the lower mold platform 100. Under the obstruction of the water baffle 103, the cooling water will not overflow. During the upward movement of the upper mold platform 200, the drain plug 212 and the recovery plug 112 are reset. At this time, the recovery port 115 on the recovery pipe 110 is connected to the cooling space, so that the cooling water in the cooling space is recovered to the water tank of the lower mold platform 100, and the connection between the water tank of the upper mold platform 200 and the drain pipe 210 is blocked by the drain plug again. At this time, water can be discharged from the water tank of the upper mold platform 200 for the next use. The accompanying waterway in this embodiment does not involve a water pump and a motor throughout the whole process. The drainage and recovery of the injection molding process are achieved only by a mechanical structure, which reduces the cost of the equipment. When the water discharge pipe 210 contacts the recovery pipe 110, the water discharge pipe 210 discharges cooling water into the cooling space; when the water discharge pipe 210 is separated from the recovery pipe 110, the recovery pipe 110 recovers the cooling water in the cooling space; Furthermore, in order to prevent the drain plug 212 from detaching from the drain pipe 210 and becoming unable to return to its original position, evenly distributed positioning grooves 213 are machined around the drain plug 212; the outer wall at the top end of the drain pipe 210 is fixedly connected with evenly distributed positioning support rods 211, and a positioning block is provided on the top of the positioning support rod 211, and the positioning block is slidably connected to the inner wall of the positioning groove 213. The drain plug 212 is restricted from moving on the central axis of the drain pipe 210 through the positioning grooves 213 around the drain plug 212 and the positioning blocks on the positioning support rod 211, thereby preventing the drain plug 212 from detaching from the drain pipe 210 and becoming unable to return to its original position.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
