[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Example 1: A deep cavity spiral tooth-recessed injection molding mold, see Figures 1 to 4 , including a deep cavity mold body 1, a servo motor body 2 is arranged on a mounting frame at the transmission end of the deep cavity mold body 1, and also includes a protective structure 3;

[0036] The protective structure 3 is arranged on the mounting frame at the driving end of the deep cavity mold body 1;

[0037] The protection structure 3 includes baffle A301, baffle B302 and baffle C303;

[0038] The two baffles A301 are respectively fixed on the front and rear ends of the top side of the mounting frame of the transmission end of the deep cavity mold body 1; the baffle B302 is fixed on the outer end of the top side of the mounting frame of the transmission end of the deep cavity mold body 1; wherein, the two ends of the baffle B302 are respectively fixedly connected to the outer ends of the opposite sides of the two baffles A301, and the baffle B302 and the two baffles A301 form a U-shaped plate; the two baffles C303 are respectively arranged on the top ends of the two baffles A301; wherein, the two baffles C303 are closed and matched with the top opening of the U-shaped plate.

[0039] The utility model has the advantage of blocking the opening above the mounting frame where the connection between the drive shaft of the servo motor and the transmission mechanism in the mold is located by arranging baffles A301, B302 and C303, thereby preventing dropped objects from entering the mounting frame and hitting the connection. This solves the problem that the connection between the drive shaft of the servo motor and the transmission mechanism in the mold is exposed outside the mold, the working environment of the mold is poor, and there is a possibility of dropped objects hitting the transmission connection.

[0040] Specifically, guide plates 305 are fixedly disposed on opposite sides of the two baffles A301, and connecting plates 304 are sleeved on the two guide plates 305. Tops of opposite sides of the two connecting plates 304 are fixedly connected to opposite ends of the two baffles C303.

[0041] The utility model has the advantage of two movable baffles C303 by setting the guide plate 305 and the connecting plate 304. The two baffles C303 move away from each other to open the top opening of the mounting frame, which is convenient for adding lubricating oil to the connection between the transmission shaft of the servo motor and the transmission mechanism in the mold.

[0042] Furthermore, a limiting plate 306 is fixedly disposed at opposite ends of the two guide plates 305 .

[0043] The utility model has the advantage of preventing the connection plate 304 from being separated from the guide plate 305 by setting the limiting plate 306, thereby preventing the baffle C303 from being separated.

[0044] Furthermore, the two baffles C303 are positioned and matched at opposite ends by a positioning assembly 307;

[0045] The positioning assembly 307 includes a connecting block A 3071, a connecting block B 3072, a rotating plate 3074 and a stopper 3075;

[0046] The connecting block A3071 and the connecting block B3072 are respectively fixed on the top side of the opposite end of the two baffles C303; one end of the opposite side of the two rotating plates 3074 is rotatably connected with the two ends of the connecting block B3072 through the torsion spring 3073; the two ends of the torsion spring 3073 are respectively connected with the rotating plate 3074 and the connecting block B3072, and the elastic coefficient of the torsion spring 3073 is selected and used by the technical personnel of this profession according to the actual situation; the two blocks 3075 are respectively fixed on the other end of the opposite side of the two rotating plates 3074; wherein, one side of the block 3075 is limitedly matched with the end of the connecting block A3071.

[0047] The utility model has the advantage of fixing the two baffles C303 relatively to each other after the two baffles C303 are in contact at one end by setting a connecting block A3071, a connecting block B3072, a torsion spring 3073, a rotating plate 3074 and a stopper 3075. At this time, the two connecting plates 304 respectively contact the outer sides of the baffles A301 to limit each other, and the two baffles C303 form a whole to maintain a stable closure on the top opening of the mounting frame.

[0048] It is worth mentioning that the other side of the stopper 3075 is set as an inclined surface 3076. When the two baffles C303 move relative to each other and contact, the inclined surface 3076 first contacts the end of the connecting block A3071, and pushes the stopper 3075 along the inclined surface 3076 to rotate the rotating plate 3074, and the torsion spring 3073 is compressed until the two baffles C303 contact one end relative to each other, and the stopper 3075 loses its extrusion. The torsion spring 3073 drives the rotating plate 3074 to rotate so that the stopper 3075 blocks the end of the connecting block A3071 for positioning.

[0049] Working principle: When using the device of the utility model, baffles A301, B302 and C303 block the opening above the mounting frame where the drive shaft of the servo motor is connected to the transmission mechanism in the mold, to prevent falling objects from entering the mounting frame and hitting the connection. When lubricating the connection, the two baffles 3075 push outward to make the rotating plate 3074 rotate outward until the baffle 3075 no longer blocks the end of the connecting block A3071, the two baffles C303 move away from each other, and the connecting plate 304 moves outward along the guide plate 305, opening the top opening of the mounting frame, and adding lubricating oil to the connection between the drive shaft of the servo motor and the transmission mechanism in the mold from the opening. Then the two baffles C303 are moved relative to each other. When the two baffles C303 move relative to each other and contact, the inclined surface 3076 first contacts the end of the connecting block A3071, and the stopper 3075 is pushed along the inclined surface 3076 to make the rotating plate 3074 rotate, and the torsion spring 3073 is compressed until the two baffles C303 contact at one end relative to each other, and the stopper 3075 loses its extrusion. The torsion spring 3073 drives the rotating plate 3074 to rotate so that the stopper 3075 blocks the end of the connecting block A3071 for positioning.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
