Abstract
Description
Technical Field

[0002] As a medical device, a cutting stapler is mainly controlled by a handle provided thereon during use. The handle is mainly injection-molded by an injection molding machine. The formed handle injection molding is an integrated structure. A fixed template and a movable template for injection molding the handle injection molding are provided on the injection molding machine. A mold cavity equal to the outer shape of the handle injection molding is provided in the movable template.
[0003] The injection molding raw material is mainly filled in the mold cavity. When an ejecting component on the movable template ejects the formed injection molding, since the outer wall of the injection molding is closely attached to the inner wall of the mold cavity, the injection molding will adhere to the inner wall of the mold cavity during discharging, resulting in some residues remaining on the inner wall of the mold cavity. Moreover, one end of the ejecting component also contacts the outer wall of the injection molding formed in the mold cavity, so there are also some residues at one end of the ejecting component. When there are residues on the inner wall of the mold cavity, it will cause the inner wall of the mold cavity to be uneven, affecting the flatness of the outer wall of the next injection molding. When there are residues at one end of the ejecting component, when the residues at one end of the ejecting component contact the injection molding in the mold cavity, it will cause wear of the injection molding, affecting the integrity of the injection molding. Aiming at the deficiencies of the prior art, we propose a handle processing mold for a cutting stapler to solve the above problems. Summary of the Utility Model

[0031] By providing a handle processing mold for a cutting stapler in the embodiments of the present application, the problem that when there are residual injection molding residues on the inner wall of the mold cavity and one end of the top part, it will affect the flatness of the outer surface of the next injection molded part, resulting in poor quality of the injection molded part, is solved, and the cleaning of the residual injection molding residues on the inner wall of the mold cavity and one end of the top part is realized.
[0032] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0033] The embodiments of the present utility model disclose a handle processing mold for a cutting stapler.
[0034] According to the attached Figures 1-6As shown in the figure, it includes a fixed template 1 and a movable template 2 arranged on an injection molding machine. One side of the fixed template 1 is fixedly connected with a guide rod 11. One end of the movable template 2 is slidably arranged on the outer wall of the guide rod 11. A mold cavity 21 is formed on one side of the movable template 2. A hollow push rod 3 for forming the discharge of the mold is arranged on the inner wall of the mold cavity 21. The outer shape of the mold cavity 21 is equal to the outer shape of the handle of the cutting stapler. A connecting hole 22 communicating with the mold cavity 21 is formed inside the movable template 2. The hollow push rod 3 is slidably arranged inside the connecting hole 22. One side of the movable template 2 away from the fixed template 1 is fixedly connected with a side frame 31. One side of the side frame 31 is fixedly connected with a first cylinder 32 for driving the hollow push rod 3 to move.
[0035] When injecting and molding the handle of the cutting stapler, start the driving device on the injection molding machine, so that the movable template 2 moves along the guide rod 11 to one side of the fixed template 1. At this time, the fixed template 1 and the movable template 2 are in a closed state. Then, start the extrusion device on the injection molding machine, so that the raw material enters the mold cavity 21 through the injection port on the fixed template 1. When the raw material in the mold cavity 21 is shaped, it is the required handle of the cutting stapler. The handle of the cutting stapler is not specifically drawn in the attached drawing. Then, move the movable template 2 away from the fixed template 1 through the driving device, so that the mold cavity 21 is exposed. Then start the first cylinder 32, so that the first cylinder 32 drives the hollow push rod 3 to move, so that the hollow push rod 3 ejects the formed handle from the mold cavity 21, and the discharge of the formed handle is completed.
[0036] A cleaning mechanism 4 is arranged on the outer wall of the hollow push rod 3. Through the arranged cleaning mechanism 4, the remaining material adhering to the inner wall of the mold cavity 21 is cleaned to ensure the smoothness of the inner wall of the mold cavity 21. The cleaning mechanism 4 includes air outlet holes 41, which are opened on the outer wall of the hollow push rod 3 and are evenly distributed on the outer wall of the hollow push rod 3. An air pump 42 is arranged on one side of the movable template 2. A connecting pipe 43 is fixedly connected with one end of the hollow push rod 3 and is communicated with the inside of the hollow push rod 3. The other end of the connecting pipe 43 is connected with the air pump 42. The air pump 42 is fixedly arranged on one side of the side frame 31.
[0037] A scraping component 5 is arranged inside the connecting hole 22. The scraping component 5 is used to clean the end of the hollow push rod 3 away from the connecting pipe 43, that is, to clean the end of the hollow push rod 3 in contact with the raw material in the mold cavity 21. The scraping component 5 includes a through hole 51 opened on the inner wall of the connecting hole 22, a scraping plate 52 slidably arranged inside the through hole 51, and a second cylinder 53 for driving the scraping plate 52 to move up and down. The second cylinder 53 is fixedly arranged inside the through hole 51. The through hole 51 is not communicated with the inside of the mold cavity 21. After the scraping plate 52 scrapes and cleans the remaining material at the end of the hollow push rod 3, the scraped remaining material is discharged to the external environment through the opening at the bottom of the through hole 51.
[0038] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model.
