Abstract
A pin plate fixing structure for grinding and assembling an injection mold comprises a base plate, a pin plate component located above the base plate, and an ejector rob fixed on the pin plate component, wherein a first bolt hole is arranged in the base plate, a second bolt hole corresponding to the first bolt hole is arranged in the pin plate component, a fixing bolt penetrates through the first bolt hole and the second bolt hole, a plurality of stop pins are installed on the periphery of the first bolt hole on the base plate, a gap is arranged between the base plate and the lower surface of the pin plate component, and pin caps of the stop pins are pre-posed in the gap. Compared with the prior art, the pin plate fixing structure for grinding and assembling the injection mold is applicable to large and medium sized molds, can fix the base plate and the pin plate component on the middle portion of the pin plate fixing structure, guarantees grinding and assembling accuracy of an ejector mechanism, has a function of preventing manual faulty operations, and simultaneously is simple in structure and convenient and fast to operate.
Description
Technical field
The utility model relates to the injection mold technical field, is specifically related to a kind of injection mold bedding-in needle plate fixed structure.
Background technology
In the injection mold development process, usually need to carry out bedding-in to it, especially ejecting mechanism length is carried out bedding-in, make mould meet instructions for use.In the bedding-in process, need to be fixed ejector retainner plate, existing method is mainly between moving platen and ejector retainner plate, adjusting bolt to be installed, there is following defective in it: because can only be fixed in the surrounding of Die and mould plate, for larger-size mould, the zone in the middle of ejector retainner plate can't be fixed, like this, can cause the ejecting mechanism length that develops inaccurate, affect mould and die accuracy; Because adjusting bolt and moving platen and ejector retainner plate all can relative motions, main its highly fixedly ejector retainner plate that relies on, the randomness that install the position is larger, when practical operation, might be arranged on the position that the rubbish nail is not set, owing to leaving the space between ejector retainner plate and base plate, when bedding-in, cause the ejector retainner plate distortion, cause bedding-in ejecting mechanism length out not accurate enough.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of injection mold bedding-in needle plate fixed structure, and the precision with ejecting mechanism after the raising bedding-in satisfies instructions for use.
For achieving the above object, the utility model adopts following technical scheme:
Injection mold bedding-in needle plate fixed structure, comprise base plate, be positioned at base plate top the needle plate assembly, be fixed on the push rod on the needle plate assembly, offer the first bolt hole on base plate, offer second bolt hole corresponding with the first bolt hole on the needle plate assembly, in the first bolt hole and the second bolt hole, cross-under has a set bolt, the periphery that is positioned at the first bolt hole on base plate is equipped with a plurality of rubbish nails, have a gap between the lower surface of base plate and needle plate assembly, the head of a nail of rubbish nail is prepended in this gap.
The needle plate assembly comprises the face needle plate of the section of being located thereon and the end needle plate that is fixedly connected on face needle plate lower surface, and the second bolt hole is opened on end needle plate.
The beneficial effects of the utility model are:
Than prior art, the utility model is applicable to large and medium-sized injection mold, can be fixed base plate and needle plate assembly in the middle part, guarantees the precision of ejecting mechanism bedding-in, has the function of the artificial incorrect operation of preventing; Simultaneously, it is simple in structure, simple operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1, base plate; 11, the first bolt hole; 2, end needle plate; 21, the second bolt hole; 3, face needle plate; 4, set bolt; 5, rubbish nail; 6, push rod.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, be a kind of injection mold bedding-in needle plate fixed structure of the utility model, comprise base plate 1, be positioned at the needle plate assembly of base plate 1 top and be fixed on push rod 6 on the needle plate assembly, the needle plate assembly comprises the face needle plate 3 of the section of being located thereon and the end needle plate 2 that is fixedly connected on face needle plate 3 lower surfaces, and the bottom of push rod 6 is fixed between face needle plate 3 and end needle plate 2.offer the first bolt hole 11 on base plate 1, offer the secondth bolt hole 21 on end needle plate 2, the second bolt hole 21 and the first bolt hole are corresponding Shang Xia 11, its both inner cross-under one set bolt 4 is arranged, utilize set bolt 4 that base plate 1 and end needle plate 2 is fixing, namely base plate 1 and needle plate assembly are fixed together, be positioned at the first bolt hole 11 peripheries on base plate 1 a plurality of rubbish nails 5 are installed, has a gap between the lower surface of base plate 1 and needle plate assembly (the namely lower surface of end needle plate 2), the head of a nail of rubbish nail 5 is placed in this gap, be used for support base needle plate 2.
in said structure, usually arrange respectively on end needle plate 2 and base plate 1 in correspondence with each other 4-8 the second bolt hole 21 and the first bolt hole 11 as fabrication hole, when needs carry out bedding-in to ejecting mechanism, the direct set bolt 4 of screwing in the bottom of base plate 1, base plate 1 and end needle plate 2 are fixed together, owing to being bottom cross-under set bolt 4 from base plate 1, therefore, set bolt 4 to offer the position unrestricted, can be arranged on mold periphery, also can be arranged on the middle part of mould, thereby guarantee that the middle part of base plate 1 and end needle plate 2 are fixing, can guarantee the accuracy of ejecting mechanism bedding-in, at set bolt 4 peripheries, a plurality of rubbish nail 5 is set, can places set bolt 4 and pull the end during needle plate 2, deformation occur in end needle plate 2, the first bolt hole 11 places at base plate 1 arrange sign, have the function of the artificial incorrect operation of preventing.
Those skilled in the art can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
