Abstract
The utility model relates to a mold component, in particular to a safety device of a mold, which comprises a line, a thimble board located under the line and a thimble arranged on the thimble board. The thimble board is provided with a safety rod. The line is provided with a keepoff hole. When the line is reset normally, the safety rod extends into the keepoff hole the aperture of which is larger than the diameter of the safety rod. The utility model has the beneficial effect that by adding the safety rod to the thimble board and mounting the keepoff hole at the corresponding position on the line, when the mold is made and the line can not be reset as usual because of various factors, the safety rod and the line are in a blocking state, the thimble can not extend out and interfere with the line, and thereby the mold damage is avoided and the production cost is saved.
Description
Technical field
The utility model relates to a kind of assembly of mould, particularly a kind of safety device of mould.
Background technology
Traditional mould comprises moulding section, ejecting mechanism, resetting-mechanism, core-pulling mechanism, guiding mechanism, running gate system, heat-exchange system etc., ejecting mechanism comprises ejector retainner plate and the thimble of being located on the ejector retainner plate, thimble is positioned at below, row position, after mould is finished injection mo(u)lding, rocking bar drive line displacement is moving looses core to finish, and thimble ejects product then.Normal in the production process because some uncertain factors, when the mould die sinking, the row bit architecture goes wrong or row position contents damages, as spring, row position lock etc., cause the row position normally not reset, can make the thimble of row position below by force hit row position when ejecting product this moment, cause thimble to damage, wound in row position, mould damages, and then influence the personal safety that the ordinary production progress of mould reaches the operator and increased hidden danger.
The utility model content
The purpose of this utility model is to provide a kind of safety device of mould, can effectively avoid mold damage when the row position can not normally reset.
For addressing the above problem, the utility model adopts following technical scheme:
The safety device of mould comprises the ejector retainner plate of going the position, being positioned at below, row position, is installed in the thimble on the ejector retainner plate, described ejector retainner plate is provided with safety pole, described row position is provided with emptiness avoiding hole, and described safety pole stretched into described emptiness avoiding hole when the position of being expert at normally resetted, and the emptiness avoiding hole aperture is greater than the safety pole diameter.
Described safety pole has two at least, and described emptiness avoiding hole has two at least.
Compared with prior art, the utlity model has following beneficial effect: by on ejector retainner plate, increasing safety pole, correspondence position is gone up in the row position increases emptiness avoiding hole, during die sinking, when row position can not normally reset because of various factors, safety pole was in the dieback state with the row position, can not produce thimble and eject with the row position and a situation of interfering occurs, avoid mold damage, save production cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done further detailed description.
Fig. 1 is mould structural representation of the present utility model when being in the matched moulds state.
Fig. 2 be row position motion just often mould eject state structural representation of the present utility model.
Fig. 3 be row position motion when improper mould eject state structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 to Figure 3, the safety device of mould, comprise the ejector retainner plate 3 of going position 1, being positioned at 1 below, row position, be installed in the thimble 4 on the ejector retainner plate 3, ejector retainner plate 3 is provided with safety pole 2, the distance that the position of corresponding safety pole 2 adds behind the up position stroke S1 on the row position 1 is provided with emptiness avoiding hole 5, and the aperture of emptiness avoiding hole 5 is greater than the diameter of safety pole.
As shown in Figure 1, when mould was in the matched moulds state, the distance between emptiness avoiding hole 5 and the safety pole 2 equaled row position stroke S1.As shown in Figure 2, during 1 proper motion of row position, ejector retainner plate 3 is being with thimble 4 and safety pole 2 bars to go ahead, and product 7 tops far from the back mould, under the effect that ejects limited block 6, are ejected termination, and this moment, safety pole 2 stretched in the emptiness avoiding hole 5.As shown in Figure 3, if during the improper motion in row position 1, emptiness avoiding hole 5 fails to get back to the normal position, this moment safety pole 2 with row 1 dieback (being that zero stroke ejects), can not produce any problem that ejects interference.
Claims (2)
1. the safety device of mould, comprise the ejector retainner plate of going the position, being positioned at below, row position, be installed in the thimble on the ejector retainner plate, it is characterized in that: described ejector retainner plate is provided with safety pole, described row position is provided with emptiness avoiding hole, be expert at the position when normally resetting described safety pole stretch into described emptiness avoiding hole, the emptiness avoiding hole aperture is greater than the safety pole diameter.
2. according to the safety device of the described mould of claim 1, it is characterized in that: described safety pole has two at least, and described emptiness avoiding hole has two at least.
