[0066] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0067] Example 1

[0069] like Figure 1 and Figure 3 As shown, the scraping mechanism 6 includes a U-shaped oblique scraper 61, a rodless cylinder 62 and a fixed rod 63.

The fixed rod 63 is connected to the middle and front side of the upper part of the machine tool 1. The fixed rod 63 is slidably connected to the U-shaped oblique scraper 61. The U-shaped oblique scraper 61 is driven downward by the rodless cylinder 62, so that the plastic liquid adhering to the injection molding gun 5 can be scraped off cleanly by the U-shaped oblique scraper 61.

[0070] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the brush mechanism 7 includes a roller brush 71, a rotating member 72, a first roller 73, a connecting frame 74, a torsion spring 75, a wedge rod 76, a first spring 77, a first shift rod 78 and a second spring 79. The upper part of the fixed rod 63 is slidably connected to the connecting frame 74, and a first spring 77 is wound between the lower side of the front part of the connecting frame 74 and the upper part of the fixed rod 63. The first spring 77 is wound around the fixed rod 63. The rear of the connecting frame 74 is rotatably connected to the rotating member 72, and the rear side of the rotating member 72 is rotatably connected to the roller brush 71. The roller brush 71 is made of elastic material. The first roller 73 is extruded and matched with the injection gun 5. The roller brush 71 is used to be inserted into the discharge port, so that it can The plastic liquid near the discharge port is pushed into the inside of the injection molding gun 5 to prevent the discharge port from being blocked. The first roller 73 is rotatably connected to the lower right side of the rear of the rotating member 72. A torsion spring 75 is wound between the front of the rotating member 72 and the connecting frame 74. The torsion spring 75 is wound on the rotating member 72. The front side of the right part of the connecting frame 74 is slidably connected to a wedge rod 76. The lower part of the wedge rod 76 is pressed and fitted with an inclined surface with a lower left and a higher right. The lower part of the wedge rod 76 is pressed and fitted with the U-shaped oblique scraper 61. A second spring 79 is connected between the left side of the upper part of the wedge rod 76 and the connecting frame 74. The middle side of the upper front part of the machine tool 1 is connected to a first shift rod 78, and the first shift rod 78 is pressed and fitted with the inclined surface of the lower part of the wedge rod 76.

[0071] When using the present rainproof shoe cover injection molding device to produce shoe covers, first, a collection box for receiving materials can be placed on the middle side of the upper inner part of the machine tool 1, and then the storage barrel 4 is connected to the external feeding device, so that the plastic liquid enters the storage barrel 4, and then flows into the injection molding gun 5 through the storage barrel 4, and the machine tool 1 is started, and the plastic liquid in the injection molding gun 5 is heated to keep the plastic liquid in the injection molding gun 5 in a liquid state, and the injection molding splint 2 is rotated and closed toward the side close to each other, so that it can surround the lower part of the injection mold 3, and then the machine tool 1 is controlled to make the injection molding splint 2 and the injection mold 3 move to the right close to the discharge port of the injection molding gun 5, and the plastic liquid in the injection molding gun 5 is transported into the injection molding splint 2 through the discharge port, so that the injection molding splint 2 is filled with plastic liquid, thereby To produce shoe covers, when the injection molding plywood 2 can no longer contain the plastic liquid, the external feeding device temporarily stops feeding, but a small amount of plastic liquid may still overflow and adhere to the left side of the injection molding gun 5. Then the machine tool 1 is controlled to move the injection molding plywood 2 and the injection mold 3 to the left and reset. After the plastic liquid in the injection molding plywood 2 is roughly dry, the machine tool 1 is controlled to rotate the injection molding plywood 2 to the side away from each other and reset. Then the injection mold 3 is moved upward, driving the molded shoe cover to move upward as well, so that the shoe cover is away from the injection molding plywood 2, making it convenient for people to take away the produced shoe cover, thereby completing the production of a shoe cover. After the shoe cover is taken away, the injection mold 3 is moved downward and reset. After the injection molding plywood 2 and the injection mold 3 are moved to the left and away from the injection molding plywood, the shoe cover is moved to the left and reset. At the same time as the gun 5 is being molded, people can start the rodless cylinder 62 to move the U-shaped oblique scraper 61 downward, and the U-shaped oblique scraper 61 will contact the injection molding gun 5, so that the plastic liquid adhering to the injection molding gun 5 can be automatically scraped and wiped in time by the U-shaped oblique scraper 61. Since the plastic liquid has not solidified yet and is still in a liquid state, it is easier to scrape it clean, preventing subsequent accumulation of excessive plastic liquid from clogging the discharge port, eliminating the step of manually cleaning up excess plastic liquid, and making it more convenient for people to produce shoe covers later. The scraped plastic liquid will fall downward and flow into the collection box prepared in advance. When the U-shaped oblique scraper 61 moves downward, it will squeeze the wedge rod 76, causing the wedge rod 76 to move downward, driving the connecting frame 74 to move downward as well. When the first roller 73 is in contact with the injection molding gun 5, the lower part of the roller brush 71 is approximately located at the position of the discharge port of the injection molding gun 5. The first roller 73 rolls under the action of friction, and the rotating member 72 and the first roller 73 are squeezed by the shape of the injection molding gun 5. The first roller 73 rolls to the lower left side along the injection molding gun 5, so that the rotating member 72 drives the roller brush 71 to rotate counterclockwise, and the torsion spring 75 is twisted, so that the roller brush 71 is inserted into the injection molding gun 5 through the discharge port. Since the roller brush 71 is made of elastic material, it can be deformed appropriately to better enter the injection molding gun 5. As the U-shaped scraper 61 continues to move downward,The wedge rod 76 and the connecting frame 74 will also move downward, causing the first roller 73 to continue to roll to the lower left side. The rotating member 72 rotates counterclockwise at a larger angle, and the roller brush 71 will penetrate deeper into the injection molding gun 5, thereby pushing the plastic liquid accumulated at the discharge port into the injection molding gun 5 through the roller brush 71 to prevent the discharge port from being blocked, thereby making it easier for people to continue to produce shoe covers. When the inclined surface on the wedge rod 76 contacts the first shift rod 78, the first shift rod 78 will squeeze the inclined surface on the wedge rod 76, causing the wedge rod 76 to move to the left, and the second spring 79 will be pressed. When the wedge rod 76 is compressed, the lower part of the wedge rod 76 will be away from the U-shaped oblique scraper 61. After the wedge rod 76 is no longer squeezed by the U-shaped oblique scraper 61, it will move upward and reset under the action of the first spring 77, driving the connecting frame 74 to move upward and reset as well. This will give the rotating member 72 an upward force, causing the first roller 73 to roll to the upper right side along the injection gun 5, thereby causing the rotating member 72 to gradually rotate in the opposite direction under the action of the torsion spring 75, driving the roller brush 71 to also rotate in the opposite direction and reset. When the rotating member 72 and the roller brush 71 are completely rotated in the opposite direction and reset, the connecting frame 74 will continue to drive The rotating member 72 moves upward and resets, thereby causing the first roller 73 and the roller brush 71 to move upward and reset. When the inclined surface on the wedge rod 76 moves away from the first shift rod 78, the wedge rod 76 will move to the right and reset under the action of the second spring 79. When the U-shaped oblique scraper 61 can no longer move downward, the rodless cylinder 62 is controlled to move the U-shaped oblique scraper 61 upward and reset, and then the rodless cylinder 62 is temporarily stopped. People can refer to the above steps to produce the next shoe cover. When all shoe covers are produced, the machine tool 1 and the rodless cylinder 62 are turned off, and the outer The feeding device stops delivering the plastic liquid. In summary, people can use the rodless cylinder 62 to move the U-shaped oblique scraper 61 downward, and use the U-shaped oblique scraper 61 to automatically scrape off the plastic liquid adhering to the injection molding gun 5 in time, avoiding excessive accumulation and clogging of the discharge port, thereby eliminating the need for people to perform additional manual cleaning steps. The rotating member 72 drives the roller brush 71 to rotate counterclockwise, so that the roller brush 71 can push the plastic liquid at the discharge port of the injection molding gun 5 inward, further preventing clogging of the discharge port and making it easier for people to continue producing shoe covers.

[0072] Example 2

[0073] On the basis of Example 1, Figure 1 、 Figure 7 and Figure 8As shown, a heating mechanism 8 is also included, which includes a heater 81, a second lever 82, a push switch 83 and an arc rod 84. The front and rear sides of the left part of the U-shaped oblique scraper 61 are connected to the arc rod 84. The heater 81 for heating the plastic liquid is connected between the two sides of the left part of the arc rod 84. The right rear side of the rear arc rod 84 is connected to the second lever 82. The left side of the upper rear part of the machine tool 1 is connected to the push switch 83. The push switch 83 is electrically connected to the heater 81, and the push switch 83 is squeezed into fit with the second lever 82.

[0074] In the initial state, the second lever 82 squeezes the press switch 83, that is, the press switch 83 is in a pressed state, and the heater 81 is in a turned-off state. When the U-shaped oblique scraper 61 moves downward, it drives the arc rod 84 to move downward, so that the heater 81 and the second lever 82 move downward, and the second lever 82 moves away from the press switch 83. After the press switch 83 is no longer squeezed by the second lever 82, it will automatically rebound, which will send a signal to the heater 81 to start the heater 81. When the heater 81 moves to the vicinity of the discharge port on the injection molding gun 5, the plastic liquid near the discharge port can be heated by the heater 81. Thereby, the plastic liquid near the discharge port can be kept in a liquid state at all times to prevent it from solidifying too quickly, making it easier for the U-shaped oblique scraper 61 to scrape the plastic liquid clean and for the roller brush 71 to push the plastic liquid to the right, thereby preventing the discharge port from being blocked and making it easier for people to continue producing shoe covers. When the U-shaped oblique scraper 61 moves upward and resets, it will drive the arc rod 84 to move upward and reset, causing the heater 81 and the second lever 82 to also move upward and reset. When the second lever 82 contacts the press switch 83, it will squeeze the press switch 83 again, causing the press switch 83 to stop sending signals to the heater 81, thereby turning off the heater 81.

[0075] like Figure 1 、 Figure 9 and Figure 10 As shown, a cleaning mechanism 9 is also included, which includes a pulling frame 91, a replaceable rag 92, a fixed frame 93 and a third spring 94. A fixed frame 93 is connected between the front and rear sides of the upper middle part of the machine tool 1, and the upper part of the fixed frame 93 is slidably connected to the pulling frame 91. A replaceable rag 92 is placed on the right side of the front of the pulling frame 91. The replaceable rag 92 is in contact with the roller brush 71. A third spring 94 is wound between the upper and lower sides of the front of the pulling frame 91 and the fixed frame 93. The third spring 94 is wound around the fixed frame 93, and the replaceable rag 92 is driven to move by the pulling frame 91, and the replaceable rag 92 is used to wipe the roller brush 71, so that the roller brush 71 is cleaner.

[0076] When the roller brush 71 is inserted into the injection molding gun 5 and the plastic liquid is pushed to the right, the roller brush 71 will also be adhered to the plastic liquid. If too much plastic liquid is accumulated, it may be difficult for the roller brush 71 to enter the injection molding gun 5 through the discharge port, thereby causing the plastic liquid to be blocked at the discharge port and affecting the production of shoe covers. Therefore, people can move the pulling frame 91 backward so that the replaceable wiping cloth 92 also moves backward. The third spring 94 is stretched. Since the replaceable wiping cloth 92 is in contact with the roller brush 71, the roller brush 71 will rotate under the action of friction, and the replaceable wiping cloth 92 can be used to wipe the plastic liquid adhered to the roller brush 71. Then, the pulling frame 91 is released. The pulling frame 91 moves forward and resets under the action of the third spring 94, driving the replaceable wiping cloth 92 to move forward and reset as well, so that the roller brush 71 rotates in the opposite direction and resets under the action of the friction force, and the roller brush 71 can be wiped again by the replaceable wiping cloth 92, so that the roller brush 71 can be cleaner, so that the roller brush 71 can better push the plastic liquid at the discharge port to prevent the discharge port from being blocked, thereby making it more convenient for people to continue to produce shoe covers. When there is a lot of plastic liquid adhering to the replaceable wiping cloth 92, people can remove the current replaceable wiping cloth 92 and replace it with a new replaceable wiping cloth 92, thereby ensuring the cleaning effect of the replaceable wiping cloth 92 on the roller brush 71.

[0077] like Figure 1 、 Figure 11 and Figure 12 As shown, the machine tool 1 further includes a storage mechanism 10, which includes a charging box 101, a second roller 102 and a handle 103. The charging box 101 for collecting the scraped plastic liquid is slidably connected between the left and right sides of the upper middle position of the machine tool 1, and the front side of the charging box 101 is connected to the handle 103. The left and right sides of the lower part of the charging box 101 are both symmetrically connected to the second roller 102 in a front-to-back rotation manner.

[0078] In the initial state, there is already a loading box 101 on the middle side of the upper part of the machine tool 1, so people do not need to prepare an additional collection box. The plastic liquid scraped off by the U-shaped oblique scraper 61 will fall down into the loading box 101 for collection. When the plastic liquid in the loading box 101 is full, people can move the loading box 101 forward by using the handle 103, driving the second roller 102 to move forward as well, and the second roller 102 will also rotate under the action of friction, thereby reducing the friction between the loading box 101 and the machine tool 1, allowing people to move the loading box 101 full of plastic liquid out more effortlessly, and then people can take away the full loading box 101, place a new loading box 101, and push the new loading box 101 backward into the machine tool 1, so that the second roller 102 rotates in the opposite direction under the action of friction, so as to facilitate receiving the scraped plastic liquid.

[0079] like Figure 1 、 Figure 13 and Figure 14 As shown, the shifting mechanism 11 is also included, and the shifting mechanism 11 includes a scraper 111, a slide rail 112 and a fourth spring 113. The slide rail 112 is connected to the middle side of the front upper part of the machine tool 1, and the slide rail 112 is in an inclined state with the left side lower and the right side higher. The scraper 111 is slidably connected to the slide rail 112, and the left side of the rear part of the scraper 111 is provided with an inclined surface with the left side higher and the right side lower. The inclined surface on the scraper 111 is squeezed and matched with the inclined surface on the U-shaped oblique scraper 61. A fourth spring 113 is connected between the left side of the front part of the scraper 111 and the inner left side of the slide rail 112. Through the squeezing and matching between the inclined surface on the scraper 111 and the inclined surface on the U-shaped oblique scraper 61, the scraper 111 can scrape off the plastic liquid adhering to the U-shaped oblique scraper 61.

[0080] When the U-shaped oblique scraper 61 scrapes the plastic liquid adhered to the injection molding gun 5, a small amount of plastic liquid may also adhere to the U-shaped oblique scraper 61. If too much plastic liquid accumulates, it may affect the scraping and cleaning function of the U-shaped oblique scraper 61 on the plastic liquid. Therefore, the U-shaped oblique scraper 61 moves downward, which makes the inclined surface of the U-shaped oblique scraper 61 contact and squeeze the scraper 111, causing the scraper 111 to move to the lower left side, and the fourth spring 113 is compressed, so that the U-shaped scraper 111 can be scraped away by the scraper 111. The plastic liquid adhered to the oblique scraping member 61 is scraped off. Since the left side of the rear portion of the scraping member 111 is provided with an inclined surface that is higher on the left and lower on the right, the plastic liquid can be scraped off better, thereby enabling the U-shaped oblique scraping member 61 to better scrape off the plastic liquid adhered to the injection molding gun 5, thereby making it more convenient for people to produce shoe covers. When the U-shaped oblique scraping member 61 moves upward, the U-shaped oblique scraping member 61 will gradually move away from the scraping member 111, causing the scraping member 111 to move to the upper right side and reset under the action of the fourth spring 113.

[0081] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
