Abstract
The utility model relates to a mold component, in particular to a resetting mechanism of a mold, which comprises a front template, a back template, a thimble board and a resetting rod fixedly arranged on the thimble board. The back template is provided with a resetting guide hole. The utility model is characterized in that the resetting rod extends into the resetting guide hole and is always in the resetting guide hole in close mold state and open mold ejection state, the position of the front template, which corresponds to the resetting guide hole, is provided with a resetting push rod which extends into the resetting guide hole and pushes the resetting rod in the close mold state and the outer diameter of the resetting push rod is smaller than the aperture of the resetting guide hole. The utility model has the advantages that the resetting rod always stays in the resetting guide hole whether in the open mold ejection state or the close mold state, the problem that oil dirt caused by the friction between the resetting rod and the back template is taken out of the end plane of the back template by the resetting rod, thereby the oil dirt is glued to the subjacent product, pollutes a mold cavity and influences the product quality can be solved. And when coming down to take the product, a mechanical hand can not bump into the resetting rod, thus the safety performance is high.
Description
Technical field
The utility model relates to a kind of assembly of mould, particularly a kind of resetting-mechanism of mould.
Background technology
Traditional mould comprises front mould, back mould, ejection system, resetting-mechanism, guide-localization parts, running gate system, heat-exchange system etc., wherein, front template is provided with preceding die, rear pattern plate is provided with the back die, when front mould and back mould matched moulds, the die corresponding matching common airtight die cavity that forms in front and back is used for formed product.Ejection system comprises an ejector retainner plate, is fixed with some thimbles on the ejector retainner plate, and in front mould and back mould matched moulds process, ejector retainner plate resets under the promotion of resetting-mechanism.
As shown in Figure 1 and Figure 2, the resetting-mechanism of existing mold normally is made of the release link 1A that is fixed on the ejector retainner plate 10A, and described release link wears and is positioned on the rear pattern plate 7A.During matched moulds, rear pattern plate 7A and ejector retainner plate 10A all travel forward, and contact with front template 8A up to the release link 1A that is fixed on the ejector retainner plate 10A, thereby promotion ejector retainner plate 10A resets (as shown in Figure 1).During die sinking, rear pattern plate 7A moves backward, separates (as shown in Figure 2) up to front template 8A, rear pattern plate 7A.The liftout attachment 4A of injection moulding board promotes ejector retainner plate 10A and the release link 1A that is fixed thereon travels forward together subsequently, behind certain distance, the goods 9A in the rear pattern plate 7A die cavity ejected fully makes it break away from mould.
There is following shortcoming in this structure: 1. because release link and back mould have matching relationship, the greasy dirt that produces during motion can be bonded on the release link, when accumulating, greasy dirt can drop down when too much, if release link is positioned at the top of product, with the pollution mold cavity, influence product quality on the product below the greasy dirt that falls very easily adheres to; 2. after stretching, the release link 1 that is positioned at product top can hinder manipulator get product; 3. some release link is below product, if product needed is fallen automatically, then product very easily produces with release link in drop process and bumps against, and the product of wounding.
The utility model content
The purpose of this utility model is to provide a kind of resetting-mechanism of mould, and it can not interfere manipulator at the die sinking state that ejects, influence that product falls, polluted product and mould.
For addressing the above problem, the utility model adopts following technical scheme:
The resetting-mechanism of mould, comprise front template, rear pattern plate, ejector retainner plate and be fixedly installed in release link on the ejector retainner plate, rear pattern plate is provided with the guide hole that resets, it is characterized in that: described release link stretches into and resets guide hole and be positioned at the guide hole that resets all the time at matched moulds state and the die sinking state that ejects, the position of the corresponding guide hole that resets is provided with the push rod that resets that stretches into pushing tow release link in the guide hole that resets when the matched moulds state on the front template, and the push rod external diameter that resets is less than the guide hole aperture that resets.
The above-mentioned described push rod that resets is fixed on the front template by screw.
The above-mentioned described push rod bottom that resets is provided with buckle and is connected on the front mould.
The above-mentioned described push rod external diameter ratio that resets resets the guide hole aperture to when young 1 millimeter.
Compared with prior art, the utlity model has following beneficial effect: by enforcement of the present utility model, no matter can make when die sinking ejects state or matched moulds state release link stay the guide hole inside that resets, the fricative greasy dirt bar that can not be reset is taken the rear pattern plate end face out of between release link and the rear pattern plate, thereby with the pollution mold cavity, influence product quality on the product below adhering to; Manipulator can not bump against release link, the security performance height by top when getting off to get product yet; Automatically fall as product, also can release link not arranged and the product of wounding because of following.

The specific embodiment
Extremely shown in Figure 5 as Fig. 3, the resetting-mechanism of mould, comprise the release link 1 and the thimble 6 that are fixedly installed on the ejector retainner plate 10, release link 1 is passed from the guide hole 72 that resets on the rear pattern plate 7, shorten described release link 1, make when release link 1 is moved in the guide hole 72 that resets, its end face 11 is lower than the end face 71 of rear pattern plate all the time, the position of corresponding release link 1 is provided with the push rod 2 that resets on the front template 8, the push rod 2 that resets is higher than the end face 81 of front template, and spacing left between the two greater than the external diameter of the push rod 2 that resets when the push rod 2 that resets stretches into multiple hole guide hole 72 in guide hole 72 apertures that reset, spacing is more preferably greater than 0.5 millimeter, otherwise is easy to generate interference.The push rod 2 usefulness screws 3 that reset are fixed on the front mould 8.
As shown in Figure 3, during matched moulds, the push rod 2 that resets puts in rear pattern plate 7, passes the guide hole 72 that resets and contacts with release link 1, promotes release link 1 and ejector retainner plate 10 and resets.
As Fig. 4, shown in Figure 5, open mould after the formed product, product 9 is stayed on the rear pattern plate 7.Under the effect of injection machine liftout attachment 4, ejector retainner plate 10 is being with thimble 6 and release link 1 to go ahead, and product 9 tops from rear pattern plate 7, under the effect that ejects limited block 5, are ejected termination, and release link 1 free end face is still in rear pattern plate 7 the insides when ejecting termination.So the fricative greasy dirt bar that can not be reset is taken the rear pattern plate end face out of between release link and the rear pattern plate, manipulator can not bump against release link by top when getting off to get product yet, the security performance height falls automatically as product, also can release link not arranged and the product of wounding because of following.
As shown in Figure 6, push rod 2 bottoms that reset are provided with buckle 22 and are connected on the front template 8.
