Abstract
The utility model discloses an ejector device for a die, which comprises an ejector block, an ejector ret plate and an ejector plate assembly, wherein the ejector ret plate is positioned at the lower part of the ejector block; the ejector plate assembly is positioned at the lower part of the ejector ret plate; an angle ejector rod and a straight ejector rod are arranged between the ejector block and the ejector ret plate; an ejector pin which passes through the ejector ret plate is connected between the ejector block and the ejector plate assembly; and the lower part of the ejector plate assembly is provided with a driving device. The ejection device for the die has high strength, can bear a higher pressure, is difficult to fracture, cannot be deviated by an angle in the ejecting process and can be accurate to position.
Description
Technical field
The utility model relates to the injection molding technology field, is specifically related to a kind of mold liftout attachment.
Background technology
Present stage, injection mold generally adopts the ramp-roof structure depanning, because ramp-roof structure takes up room bigger, thereby in limited space, that the size of ramp-roof structure need be done is less relatively, just make that also the intensity of ramp-roof structure is less, in the backform process, this ejecting structure often ruptures, and influences production efficiency.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of mold liftout attachment, and it has higher intensity, the difficult fracture.
For achieving the above object, the utility model adopts following technical scheme:
Mold liftout attachment, comprise a jacking block, be positioned at described jacking block bottom upper plate, be positioned at the lower roof plate assembly of described upper plate bottom, angle ejector rod and straight push rod are installed between described jacking block and the described upper plate, be connected with a thimble that passes described upper plate between described jacking block and the described lower roof plate assembly, described lower roof plate assembly bottom is equipped with a drive unit.
Between described lower roof plate assembly and the described upper plate elastic reset spare is installed.
Described elastic reset spare is a back-moving spring.
Described lower roof plate assembly is provided with a spacing hole, and described upper plate lower surface connects the gag lever post of first and described spacing hole coupling.
Described drive unit is an injection machine top rod.
Described lower roof plate assembly comprises first lower roof plate that is positioned at its top and second lower roof plate that is installed in the described first lower roof plate lower surface.
The mold liftout attachment that the utility model is set forth, its beneficial effect is:
1, intensity is bigger, can bear bigger pressure, not easy fracture;
2, the process that ejects can deviation angle, can accurately locate.
Description of drawings
Fig. 1 is the structural representation of a kind of mold liftout attachment of the utility model, and describes the reset condition of its work;
Fig. 2 is the state that ejects of mold liftout attachment shown in Figure 1.
The specific embodiment
Below, in conjunction with the accompanying drawings and the specific embodiment, mold liftout attachment of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, be a kind of mold liftout attachment of the present utility model, comprise jacking block 1, upper plate 2 and two lower roof plates 3,4 that stack installation up and down from top to bottom successively, push rod 5 and angle ejector rod 6 always wherein are installed between jacking block 1 and the upper plate 2, and a thimble 7 is installed between jacking block 1 and the lower roof plate 3, thimble 7 pass upper plate 2 and can with upper plate 2 relative slips.Be positioned at that the lower surface of the lower roof plate 4 of below is connected with injection machine top rod 11, injection machine top rod 11 is as the driving element of this device, and jack-up can make progress lower roof plate 4.Owing to adopt straight push rod 5 and angle ejector rod 6 simultaneously, increased the intensity of whole device.
In order to make said apparatus in the backform process, can not depart from, lower surface at upper plate 2 has a gag lever post 8 along the extension of this device short transverse by conversion, the corresponding spacing hole 9 that on lower roof plate 3,4, offers, gag lever post 8 is inserted in this spacing hole 9, and a back-moving spring 10 also is installed between upper plate 2 and lower roof plate 3 simultaneously.
Again as shown in Figure 1, during original state, lower roof plate 4 is not subjected to the thrust that injection machine top rod 11 makes progress, as shown in Figure 2, when the startup of injection machine top rod, lower roof plate 4 is subjected to thrust upwards, and back-moving spring is compressed, then upper plate is subjected to the thrust of spring, move upward, at this moment, straight push rod and angle ejector rod act on simultaneously, jacking block is upwards pushed away, thereby finish the depanning action.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
