[0041] like Figure 1-7The mold of a wastewater collection box for a sweeping machine shown in the figure comprises a front mold assembly, a rear mold assembly, a side core pulling mechanism and a movable mold 900; the front mold assembly comprises a front mold plate 300, on which a collecting box die 301 is provided; the rear mold assembly comprises a rear mold plate 400, on which a collecting box punch 401 is provided, and the collecting box punch 401, the collecting box die 301 and the movable mold 900 form an injection molding cavity for the collecting box; the side core pulling mechanism comprises a side core 800 and a first inclined guide column 801, the side core 800 can be slidably arranged on the rear mold plate 400, and the side core 800 extends into the injection molding cavity of the collecting box , a first oblique guide column 801 is arranged on the front template 300, and a first oblique guide groove 802 corresponding to the first oblique guide column 801 is arranged on the side core 800; the movable mold 900 can be movably arranged on the front template 300, and the movable mold 900 can be slidably arranged relative to the rear template 400, and a second oblique guide groove 902 is arranged on the movable mold 900, and a second oblique guide column 901 corresponding to the second oblique guide groove 902 is arranged on the front template 300. When the mold is opened, the movable mold 900 slides away from the molded product driven by the second oblique guide column 901, and then moves together with the front template 300 to separate from the rear template 400. It is easy to understand that when the molded product needs to be demolded, the rear template 400 is separated from the front template 300, the side core 800 moves with the rear template 400, and is separated from the molded product under the action of the first inclined guide column 801, and the movable mold 900 first moves with the rear template 400, and is separated from the molded product under the action of the second inclined guide column 901, and then the movable mold 900 moves with the front template 300 and is separated from the rear template 400, which effectively avoids the side core 800 and the movable mold 900 from hindering the demolding of the product, thereby greatly improving the convenience of product demolding.

[0042] It should be noted that after the mold is closed, the collection box punch 401, the collection box die 301 and the movable mold 900 form two collection box injection cavities, and the two collection box injection cavities are isolated from each other and do not interfere with each other, so that the mold can form two products at one time, which is beneficial to improving the production efficiency of the mold. Therefore, the number of side core pulling mechanisms is two, corresponding to the two collection box injection cavities respectively.

[0043] It should be supplemented that the front mold assembly also includes a front mold fixing plate 100 and a front mold pad 200, the front mold pad 200 is arranged on the front mold fixing plate 100, the front mold plate 300 is arranged on the front mold pad 200, the rear mold assembly also includes a rear mold fixing plate 700 and a cushion block 500, the number of cushion blocks 500 is two and they are respectively arranged on both sides of the rear mold fixing plate 700, the rear mold plate 400 is arranged on the cushion block 500, the rear mold fixing plate 700 is provided with a lifting plate 600, the lifting plate 600 is provided with a plurality of ejector pins 601, the rear mold plate 400 is provided with a plurality of pinholes, each ejector pin 601 can be slidably arranged in each pinhole, when the molded product needs to be ejected, the lifting plate 600 rises under the action of an external driving member, so that the molded product is ejected by the ejector pin 601, and the demolding work is completed.

[0044] Furthermore, a first guide column 101 is provided on the front mold assembly, and a first guide hole 404 corresponding to the first guide column 101 is provided on the rear mold assembly. The first guide column 101 is slidably connected in the first guide hole 404. This arrangement can improve the stability of the movement of the mold during opening and closing. A second guide column 602 is provided on the lifting plate 600, and a second guide hole 405 corresponding to the second guide column 602 is provided on the rear mold plate 400. The second guide column 602 is slidably connected in the second guide hole 405. This arrangement can ensure the stability of the movement of the lifting plate 600 during demolding.

[0045] Please refer to Figure 5 and Figure 6In a possible implementation, a first limiting groove 903 is provided at the bottom of the movable mold 900, a first limiting member 904 is provided in the first limiting groove 903, and a second limiting member 402 is provided on the rear template 400, the second limiting member 402 extends into the first limiting groove 903 and engages with the first limiting member 904. It is easy to understand that the movement process of the movable mold 900 is divided into two steps; in the first step, the movable mold 900 slides on the rear template 400 to separate the movable mold 900 from the molded product; in the second step, the movable mold 900 moves with the front template 300 to separate the movable mold 900 from the rear template 400; it should be noted that when the movable mold 900 is in the first step, it is necessary to ensure that the movable mold 900 does not move with the front template 300, and in the second step, it is necessary to ensure that the movable mold 900 can be smoothly separated from the rear template 400. In this embodiment, the first limit member 904 is fixedly installed on the movable mold 900 by bolts, and the second limit member 402 is fixedly installed on the rear template 400 by bolts. When the mold is in the mold closing state, the first limit member 904 is engaged with the second limit member 402. Therefore, in the initial state of demolding, due to the existence of the first limit member 904 and the second limit member 402, the movable mold 900 can only slide on the rear template 400. When the movable mold 900 slides a certain distance, the first limit member 904 and the second limit member 402 are separated. At this time, the movable mold 900 moves together with the front template 300, so that the movable mold 900 is away from the rear template 400, so as to avoid the movable mold 900 causing obstruction to the molded product when the molded product is demolded; in addition, there is enough space in the first limit groove 903 for the second limit member 402 to move, so as to ensure that the movable mold 900 can slide smoothly.

[0046] In this embodiment, the first limit member 904 and the second limit member 402 are both L-shaped, so that the first limit member 904 and the second limit member 402 can be engaged with each other when they are close to each other and can be separated when they are far away from each other, which is convenient and quick. In addition, the L-shaped first limit member 904 and the second limit member 402 have a simple structure and are easy to manufacture.

[0047] Please refer to Figure 2 and Figure 6 In a possible implementation, an elastic member 905 is sleeved on the second oblique guide column 901, one end of the elastic member 905 abuts against the movable mold 900, and the other end of the elastic member 905 abuts against the front mold plate 300. It should be noted that in this embodiment, three second oblique guide grooves 902 are arranged at intervals on the movable mold 900, and correspondingly, the number of the second oblique guide column 901 and the elastic member 905 is also three, and each second oblique guide column 901 is sleeved with an elastic member 905. The setting of the elastic member 905 can play a buffering role in the movement of the movable mold 900, so that the movable mold 900 is more stable when moving, which is conducive to improving the production quality of the mold.

[0048] Please refer to Figure 2 and Figure 6 In a possible implementation, a T-shaped slide rail 304 is provided on the front mold plate 300, and a slide groove 906 cooperating with the slide rail 304 is provided on the movable mold 900. It is easy to understand that the slide rail 304 can be slidably arranged in the slide groove 906. When the mold is opened, the front mold assembly is separated from the rear mold assembly, and the movable mold 900 slides on the rear mold plate 400 under the action of the second inclined guide column 901. At this time, the slide rail 304 slides along the slide groove 906. The arrangement of the slide rail 304 and the slide groove 906 is conducive to improving the moving stability of the movable mold 900 and ensuring that the movable mold 900 can be demolded smoothly.

[0049] Please refer to Figure 3 and Figure 4 In a possible embodiment, a third stopper 303 is provided on the front template 300, and the inner side wall of the third stopper 303 conflicts with the outer side wall of the side core 800. A second stopper groove 403 is provided on the rear template 400. When the mold is closed, the lower end of the third stopper 303 is inserted into the second stopper groove 403. It should be noted that after the hot-melt material is injected into the cavity, it is cooled to form a product. When the material is cooled, the air pressure in the cavity increases, thereby forcing the side core 800 to move outward. Therefore, the third stopper 303 can limit the side core 800 to prevent the side core 800 from moving, which is beneficial to the molding of the product and improves the quality of the product. The second stopper groove 403 can make the front template 300 and the rear template 400 fit more closely. When the mold is opened, the third stopper 303 will move with the front template 300 and will not block the extraction of the side core 800.

[0050] Please refer to Figure 6 In a possible implementation, a shaping portion 907 is provided at one end of the movable mold 900 close to the collecting box convex mold 401, and the shaping portion 907 extends into the injection molding cavity of the collecting box. It is easy to understand that the outer side wall of the sewage collecting box has a vertical slot for connecting the sewage collecting box to the sweeping robot, so the shaping portion 907 is a strip-shaped protrusion to form a slot on the side wall of the sewage collecting box.

[0051] Please refer to Figure 2 and Figure 7 In a possible implementation, a shaping protrusion 302 is provided at the lower end of the collecting box female mold 301, and a shaping groove 803 corresponding to the shaping protrusion 302 is provided at one end of the side core 800 close to the collecting box male mold 401. It is easy to understand that the sewage collecting box has a handle, which can facilitate the user to take the sewage collecting box. In the mold closing state, the shaping protrusion 302 extends into the shaping groove 803 but does not contact the shaping groove 803, and the hot melt material flows into the gap between the shaping protrusion 302 and the shaping groove 803 to form a handle on the sewage collecting box.

[0052] Please refer to Figure 1and Figure 6 In a possible implementation, a cooling water pipe 908 is provided in the movable mold 900, and the cooling water pipe 908 extends to the outside of the front template 300. The front template 300 is provided with an avoidance groove 305 for avoiding the cooling water pipe 908. It should be noted that a cooling system is provided on the mold to enable the material to be cooled quickly. The cooling system includes multiple groups of cooling water pipes 908, and a group of cooling water pipes 908 is provided in the movable mold 900. Both ends of the cooling water pipe 908 need to extend out of the mold to connect to the water source. Since the movable mold 900 is located on the inner side of the front template 300, the front template 300 is provided with an avoidance groove 305, and the avoidance groove 305 is in a long strip shape, providing a movable space for the cooling water pipe 908, so that the cooling water pipe 908 can move with the movable mold 900.

[0053] Please refer to Figure 5 and Figure 7 In a possible embodiment, an elastic positioning member 406 is provided on the rear mold plate 400, and a positioning groove 804 corresponding to the elastic positioning member 406 is provided at the bottom of the side core 800. It should be noted that two positioning grooves 804 are provided at the bottom of the side core 800, and the two positioning grooves 804 are respectively located at the two ends of the movable limit distance of the side core 800. When the mold is closed, the elastic positioning member 406 extends into one of the positioning grooves 804. When the mold is released, the side core 800 slides outward, so that the elastic positioning member 406 slides into the other positioning groove 804. The setting of the elastic positioning member 406 can enable the side core 800 to be quickly positioned during the sliding process; in addition, in this embodiment, the elastic positioning member 406 is composed of a spring and a positioning block. The positioning block can be extended and retracted under the support of the spring. When the positioning block corresponds to the position of the positioning groove 804, the positioning block automatically extends into the positioning groove 804 under the action of the spring to achieve the purpose of positioning the side core 800.

[0054] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
