Abstract

The invention relates to a pre-reset mechanism for a mold. The pre-reset mechanism for the mold comprises reset rods, guide sleeves with shoulders and elastic chucks, wherein one end of each reset rod is abutted to a fixing mold bottom plate; each guide sleeve with the shoulders is arranged in a moving template; each elastic chuck is arranged in an inner hole of the corresponding guide sleeve with the shoulders; one end of each elastic chuck is fixed between an upper ejector pin plate and a lower ejector pin plate; and each reset rod is arranged in the inner hole of the corresponding guide sleeve with the shoulders and is in sliding connection with the corresponding elastic chuck. According to the pre-reset mechanism for the mold, as the reset rods which are fixed to fixed templates are adopted to be in sliding connection with the elastic chucks fixed to the corresponding ejector pin plates respectively, in the mold closing process, the reset rods move downward to drive the corresponding elastic chucks to move downward, and thus pre-reset of the ejector pin plates is finished. The pre-reset mechanism for the mold is reasonable in design, has a simple structure and is suitable for large-scale popularization.

Description

A kind of first resetting-mechanism of mould
Technical field
The present invention designs a kind of injection mold, particularly relates to one and injection mold push pedal is first resetted Mechanism.
Background technology
Injection mold, may when there being thimble in the stroke range of side core slide block when die sinking process Eject original paper with push rod etc. and produce the phenomenon interfered.Use the mould of release link, its slide block Before matched moulds return process, it is also possible to can collide with thimble, cause the damage of mould. For this phenomenon, use afterwards and be set by release link and spring to ensure that ejector retainner plate resets, It reduces the probability occurring interfering to a certain extent, but still suffers from following drawback: 1) top Pin or release link are susceptible to card wound 2) spring is lost or aging speed is fast, and shorten and use the longevity Life 3) stroke of thimble is long, and cause spring force to be not enough to ejector retainner plate and reset completely.So Need to arrange first resetting-mechanism in a mold, such as fork elder generation resetting-mechanism, cam block, gear Tooth bar elder generation resetting-mechanism etc..This kind of agency security difference and structure are complicated, and difficulty of processing is greatly and not Easily realize standardized production.
Summary of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide A kind of simple in construction, it is easy to the elder generation of dismounting and injection mold that release link service life can be extended Resetting-mechanism.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of mould first multiple Position mechanism, the release link offseted including one end and fixed clamping plate, the shoulder that has being placed in moving platen are led Set and have the collet in shoulder guide pin bushing endoporus described in being placed in, described collet one end is fixed on Between upper ejector retainner plate and lower ejector retainner plate, described release link has been placed in shoulder guide pin bushing endoporus and elastic clip Head is slidably connected.
Further, also include in order to by the described fixing briquetting having shoulder guide pin bushing to compress, described solid Level pressure block is fixing with moving platen to be connected.
Further, being provided with through hole in the middle of described fixing briquetting, this through-hole diameter is not more than elasticity The diameter of chuck collet body.
Further, described collet one end is provided with step.
Compared with prior art, it is an advantage of the current invention that: the present invention uses and is fixed on solid plate Release link be slidably connected with the collet being fixed on ejector retainner plate, during mould matched moulds, Release link moves down, and drives collet to move down, collet drive ejector retainner plate to move down, Thus realize ejector retainner plate and complete first to reset, the present invention is reasonable in design, simple in construction, is suitable for big rule Mould is promoted.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the first resetting-mechanism of a kind of mould of the present invention;
Fig. 2 is the matched moulds schematic diagram of a kind of injection mold of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention It is clearly and completely described, it is clear that described embodiment is only a present invention part Embodiment rather than whole embodiments.Based in the present invention being embodiment, this area is general The every other embodiment that logical technical staff is obtained under not making creative work premise, Broadly fall into the scope of protection of the invention.
As shown in Figure 1-2, the first resetting-mechanism of a kind of mould, including release link 1, there is shoulder to lead Set 2, collet 4 and fixing briquetting 3, described release link 1 one end is placed in fixed clamping plate 5 And between solid plate 6, be synchronized with the movement so that 6 realizations pulled by release link 1 and cover half, described in have shoulder In guide pin bushing 2 is placed in moving platen 7 and being fixed by fixing briquetting 3, this fixing briquetting 3 leads to Cross and be threadedly connected to moving platen 7, described release link 1 through have shoulder guide pin bushing 2 endoporus and with elasticity Chuck 4 is slidably connected, and described collet 4 collet body has been placed in shoulder guide pin bushing 2 endoporus its another End is fixed between ejector retainner plate 8 and lower ejector retainner plate 9, is provided with logical in the middle of described fixing briquetting 3 Hole, described collet 4 is through this through hole and has stretched into shoulder guide pin bushing 2 endoporus, this through-hole diameter Being not more than the diameter of collet 4 collet body, described collet 4 one end is provided with step 41, So that collet 4 is fixed.
During matched moulds, release link 1 has shoulder guide pin bushing 2 relatively to bottom offset, treats that release link 1 enters bullet Property chuck 4, collet 4 clamps release link 1, by release link 1 drive collet 4 to Bottom offset, drives ejector retainner plate to move down by collet 4, thus completes ejector retainner plate elder generation horizontal reset. After ejector retainner plate resets completely, collet 4 stops moving down, and release link 1 continues to move down, directly Complete to matched moulds.
Compared with prior art, it is an advantage of the current invention that: the present invention uses and is fixed on solid plate Release link 1 be slidably connected with the collet 4 being fixed on ejector retainner plate, in mould matched moulds process In, release link 1 moves down, and drives collet 4 to move down, collet 4 drives top Needle plate moves down, thus realizes ejector retainner plate and complete first to reset, and the present invention is reasonable in design, simple in construction, It is suitable for large-scale promotion.
Last it is noted that above example is only in order to illustrate technical scheme, and Non-to its restriction;Although the present invention being described in detail with reference to previous embodiment, ability Territory it will be appreciated by the skilled person that it still can be to the technical side described in foregoing embodiments Case is modified, or replaces wherein portion of techniques feature on an equal basis;And these amendment or Person replaces, and does not make the essence of appropriate technical solution depart from various embodiments of the present invention technical scheme Spirit and scope.
