[0032] The principles of the utility model will be described in detail below in combination with the drawings and examples.

[0033] The utility model provides a kind of as shown in figure 1 Figures 1-7 The utility model discloses a motor rubber sleeve mold for injection molding production of air-blast motor rubber sleeve, motor rubber sleeve mold successively includes front mold fixed plate 1, water gap plate 2, front mold 3, back mold 4, push plate 5 and back mold fixed plate 6, and the product glue injection cavity 7 is formed in the inside after front mold 3 and back mold 4 are closed, and front mold 3 is provided with inclined top column 31 and oil cylinder 32 for driving the telescopic top column 31. Rubber sleeve 8 is inverted cup shape in the mold, waist is in, and cup mouth is provided with thread 81, and is provided with inclined perforation 82 close to top. When closing, top column 31 extends into product glue injection cavity 7, and is used for reserving inclined perforation 82 when rubber sleeve 8 is formed. Before opening, top column 31 is separated from product glue injection cavity 7, so that the formed workpiece is smoothly demoulded.

[0034] In this embodiment, the motor rubber sleeve mold has at least two product glue injection cavities 7 when the mold is closed. The front mold fixed plate 1 is provided with a glue injection port 11, and the water nozzle plate 2 is provided with a flow divider 21. The liquid inlet of the flow divider 21 communicates with the glue injection port 11, and the liquid outlet of the flow divider 21 communicates with the product glue injection cavity 7 through the flow guide pipe 22.

[0035] In this embodiment, the rear mold 4 includes a pair of oppositely arranged surrounding plates 41. Each surrounding plate 41 is fixedly provided with a row position 42 at the back, and the top of the row position 42 is provided with a guide hole 43 extending downward. The front mold 3 is provided with a top rod 33, which extends obliquely downward into the guide hole 43. The surrounding plates 41 are driven to close and open the mold through the row positions 42, and the row positions 42 are controlled by the top rod 33 extending into them. When the top rod 33 lifts the front mold 3 away from the rear mold 4, it guides the pair of row positions 42 to move away from each other. When the top rod 33 lowers the front mold 3 to approach the rear mold 4, it guides the pair of row positions 42 to approach each other. The motor rubber sleeve mold has more than one product glue injection cavity 7. When the mold is opened, the pair of surrounding plates 41 are separated laterally, and the molded workpiece is demolded along the discharge channel 44 that penetrates the motor rubber sleeve mold, improving production efficiency.

[0036] In this embodiment, the rear mold 4 is also provided with a sliding groove 45, and the row position 42 is slidingly installed in the sliding groove 45.

When the mold is closed, the push rod 52 pushes the rear mold 4 to move close to the front mold 3, the line position 42 pushes a pair of surrounding plates 41 to gradually close to form a product glue injection cavity 7 under the compression of the top rod 33 and the front mold inclined pressing surface 34, and the shaping column 51 extends into the product glue injection cavity 7 along with the push plate 5; then the oil cylinder 32 is started, and the oil cylinder 32 drives the top column 31 to deeply enter the product glue injection cavity 7; after the above steps are completed, the injection molding machine starts to inject the molten glue through the glue injection port 11. When the mold is opened, first, the oil cylinder 32 drives the top column 31 to move away from the cooled and formed rubber sleeve 8, then the rear mold 4 gradually moves away from the front mold 3 under the pulling of the push rod 52, the shaping column 51 moves away from the rubber sleeve cup along with the push plate 5, and the top rod 33 also gradually moves out of the guide hole 43, under the action of the top rod 33, the two line positions 42 drive the two surrounding plates 41 to slide away from each other, the separated pair of surrounding plates 41 form a discharging channel 44 penetrating through the motor rubber sleeve mold, and the pushing rod (not shown in the drawing) outside the motor rubber sleeve mold extends into the discharging channel 44 to push the rubber sleeve 8 to separate from the flow guide pipe 22 and move away from the motor rubber sleeve mold along the discharging channel 44.

[0039] In the embodiment, the first heating pipe network 23 is arranged on the periphery of the flow divider 21, and the second heating pipe network 35 is arranged in the front mold 3, the first heating pipe network 23 is used to maintain the temperature of the molten glue in the flow divider 21, and the second heating pipe network 35 is used to maintain the temperature of the molten glue in the flow guide pipe 22, so that the waste caused by the cooling of the sol in the flow channel is avoided.

[0040] In the embodiment, the cooling pipe network 47 is arranged in the rear mold 4. The cooling pipe network 47 is used to accelerate the forming speed of the rubber sleeve 8, so as to improve the production efficiency.
