Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make clear and definite definitions of the protection scope of the present invention.

As shown in fig. 1 to 8, the utility model provides a dust collector hanger injection mold, include: the vacuum cleaner comprises a fixed die 10, a movable die, a slide block 30 and a protrusion 40, wherein the movable die is matched with the fixed die 10, the movable die is arranged on the fixed die 10 in a manner of moving up and down, the slide block 30 and the protrusion 40 are provided in two groups, the two groups are respectively arranged at the left side and the right side of a dust collector hanger 50 and are used for forming the specific structure at the left side and the right side of the dust collector hanger 50 (particularly a fixed part 52), the slide block 30 and the protrusion 40 which are arranged at the left side and the right side of the dust collector hanger 50 are taken as an example for description, as shown in figure 3, the slide block 30 is arranged between the fixed die 10 and the movable die, the slide block 30 is connected to the upper surface of the fixed die 10 in a manner of sliding left and right, the protrusion 40 extends along the left and right direction, the left end surface of the protrusion 40 is connected to the right end surface of the slide block 30, the protrusion 40 can be integrally formed with the slide block 30 or can be detachably embedded on the slide block 30, a plurality of the protrusions 40 are arranged at intervals, in the embodiment, the right end surface of the protrusion 40 is provided with a groove 41, the groove 41 extends along the left-right direction and penetrates through the protrusion 40 and the sliding block 30, the thimble 42 is slidably arranged in the groove 41, the gap (sliding fit gap) between the thimble 42 and the groove 41 is communicated with the outside air, the injection mold has a first working state, a second working state and a third working state, when the injection mold is in the first working state, the thimble 42 and the protrusion 40 jointly fill the rib 55 of the dust collector hanger 50 and form an injection mold cavity of the reinforcing rib plate 54, when the injection mold is in the second working state, the position of the thimble 42 is unchanged, the state of being pressed against the bottom wall (the surface of the middle plate 53) of the rib 55 is kept, the sliding block 30 slides leftwards relative to the thimble 42 to the protrusion 40 to be separated from the rib 55, so as to realize partial mold opening, when the injection mold is in the third working state, the position of the sliding block 30 is unchanged, the state of being kept being separated from the rib 55 is kept, the thimble 42 slides leftwards relative to be separated from the rib 55, and (3) realizing complete die opening, and naturally, if the dust collector hanger 50 needs to be taken out, moving the movable die upwards to form a space for taking out the dust collector hanger 50 between the movable die and the fixed die 10.

The benefit that sets up like this lies in, can enough reduce the protruding dynamics of dragging to gluing the position face through the postpone die sinking of thimble, avoids the deformation and the damage of reinforcing floor, and the production yield is high, can utilize the air that clearance discharge rib position department between thimble and the groove was gathered again, ensures the full gluey effect of reinforcing floor, and the production quality is high.

In the present embodiment, the groove 41 is provided with a first opening 411 on the right end surface of the protrusion 40, and when the injection mold is in the first working state, the right end surface of the thimble 42 is flush with the surface where the first opening 411 is located, so that the surface of the middle plate 53 can be more flat.

The area of the first opening 411 on the right end surface of the protrusion 40 is important, if the area is too large, the contact area between the right end surface of the thimble 42 and the glue position surface is large, and if the injection mold is in the third working state, the leftward movement of the thimble 42 will also pull the middle plate 53, thereby causing the middle plate 53 to deform or damage, if the area is too small, the contact area between the right end surface of the thimble 42 and the glue position surface is small, and if the injection mold is in the second working state, the slider 30 slides leftward, due to the reverse action of the pulling force, the pressure applied on the middle plate 53 by the thimble 42 is strong, thereby easily causing the middle plate 53 to be pushed or torn, preferably, the area of the first opening 411 is 10-20% of the area of the protrusion end surface where the first opening is located.

In this embodiment, the groove 41 is further provided with a second opening 412 on a side surface of the protrusion 40, and when the injection mold is in the second working state, a side surface of the thimble 42 is flush with a surface where the second opening 412 is located, specifically, the second opening 412 extends leftward to a connection position of the protrusion 40 and the slider 30.

Further, the first opening 411 is connected to the second opening 412, and when the injection mold is in the third operating state, the bottom surface and the side surface of the thimble 42 are flush with the surfaces of the first opening 411 and the second opening 412, respectively.

In the embodiment, three rows of rib positions 55 are provided on the fixing portion 52 of the cleaner hanger 50 from top to bottom, correspondingly, three rows of protrusions 40 are provided on the right end surface of the slider 30, and the protrusions 40 located at the top row and the bottom row are provided with the slots 41 so as to be close to the shroud 56 of the cleaner hanger 50, so that the ejector pins 42 achieve the best ejecting effect, and the protrusions 40 provided with the slots 41 are arranged at intervals for simplifying the design.

In the present embodiment, the clearance between the thimble 42 and the groove 41 is very important, and if the clearance is too large, the amount of deviation is large when the thimble 42 slides, and the reinforcing rib 54 is likely to be deviated in size, and if the clearance is too small, the exhaust efficiency is low, and the exhaust is incomplete, and it is preferable that the clearance is 0.01 to 0.03mm, and in the present embodiment, the clearance is 0.02 mm.

In order to realize the automatic change of the injection mold from the first working state → the second working state → the third working state, in this embodiment, the injection mold further comprises a slider plate 61 for connecting and driving the slider 30 to slide, an ejector plate 62 for connecting and driving the ejector pins 42 (all the ejector pins 42 penetrating the same slider 30) to slide, and a driving cylinder 63 connected to the fixed mold 10, wherein the slider plate 61 and the ejector plate 62 are arranged in parallel and spaced apart, specifically, the slider plate 61 is located at the right side of the ejector plate 62, a hydraulic rod of the driving cylinder 63 slidably penetrates the ejector plate 62 and is connected with the slider plate 61, when the driving cylinder 63 contracts, the hydraulic rod can first drive the slider plate 61, the slider 30 and the protrusion 40 to move leftward until the protrusion 40 is separated from the rib position 55, and then the slider plate 61 pushes the ejector plate 62 leftward to move the ejector plate 62 and the ejector pins 42 leftward, until the thimble 42 is separated from the rib position, the delayed mold opening of the thimble 42 is realized, and it is conceivable that the thimble 42 necessarily needs to penetrate through the slider plate 61.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
