Abstract
An ejector mechanism of an injection molding mould comprises a face needle plate, a bottom needle plate which is fixed on the lower surface of the face needle plate, and an ejector rod, wherein a hole which enables the ejector rod to penetrate through is formed in the face needle plate, a groove which contains the lower end portion of the ejector rod is formed in the bottom needle plate, at least one gasket is further arranged on the bottom end portion of the ejector rod, and the gasket is fixedly connected with the ejector rod through a screw. Compared with the prior art, in the ejector mechanism, when the length of the ejector rod is adjusted, only the gaskets with different numbers and different thicknesses need to be arranged, the installation process is convenient and simple to achieve, and the ejector rod can effectively be prevented from damage, and cost is lowered.
Description
Technical field
The utility model relates to the injection mold technical field, is specifically related to a kind of ejecting mechanism of injection mold.
Background technology
Injection mold comprises fixed half and moving half, and ejecting mechanism is set on dynamic model, in the Mould Machining process, need to grind debugging to whole mould.Fig. 1 is a kind of existing mold ejection mechanism, it comprises moving platen 12, jacking block 11, push rod 13, face needle plate 14, end needle plate 15, face needle plate 14 is positioned at the top of end needle plate 15, it both is bolted to connection, and offers the through hole that passes for push rod 13 on face needle plate 14, and the bottom of push rod 13 utilizes and is bolted on end needle plate 15, in the bedding-in process, if when processing the length of push rod 13, need the parts of dismounting more, labor intensive and expense are more; Because push rod 13 sizes are generally all larger, the higher and difficult processing of its material cost is in unloading process, if operate miss can cause whole push rod 13 to be scrapped.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of ejecting mechanism of injection mold, reduces the cost of ejecting mechanism bedding-in, and is easy to processing, installation.
For achieving the above object, the utility model adopts following technical scheme:
The ejecting mechanism of injection mold, comprise the face needle plate, be fixed on end needle plate, the push rod of face needle plate lower surface, has the hole of passing for push rod on the face needle plate, has the groove that holds the push rod bottom on end needle plate, the bottom of push rod also is provided with at least one pad, and pad is fixedly connected with push rod by screw.
Pad, push rod and end needle plate are bolted fixing.
The beneficial effects of the utility model are:
Than prior art, the utility model only need to arrange the pad of varying number or thickness when adjusting push rod length, and installation process is simple and convenient, and can prevent effectively that push rod is damaged, has reduced cost.
Description of drawings
Fig. 1 is the ejecting mechanism schematic diagram of a kind of injection mold of prior art;
Fig. 2 is the ejecting mechanism schematic diagram of a kind of injection mold of the utility model;
Fig. 3 is the zoomed-in view at A place in Fig. 2;
Wherein: 23, push rod; 24, face needle plate; 25, end needle plate; 26, screw; 27, pad.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
as Fig. 2, shown in 3, ejecting mechanism for a kind of injection mold of the utility model, it comprises face needle plate 24, be fixed on the end needle plate 25 of face needle plate 24 lower surfaces, push rod 23, has the hole of passing for push rod 23 on face needle plate 24, needle plate 25 upper surfaces in the end have the groove that holds push rod 23 bottoms, also be provided with at least one pad 27 in the bottom of push rod 23, pad 27 is fixedly connected on the bottom face of push rod 23 by screw 26, and pad 27 also is embedded in the groove that needle plate 25 upper surfaces in the end offer, so, when needs increase the length of push rod 23, just can be according to the size needs, the pad 27 of respective numbers or respective thickness is set.
Above-mentioned pad 27, push rod 23 and end needle plate 25 are fixedly connected with by a bolt.
In installation process, at first utilize screw 26 pad 27 to be fixed on the bottom face of push rod 23, then, the assembly after push rod 23 and pad 27 combinations is fixed on end needle plate 25.When bedding-in, if need to change the length of push rod 23, only need corresponding increase or the reduce quantity of pad 27 or the thickness of processing pad 27, so, simplified installation process, avoid damaging push rod 23.
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.
Claims (2)
1. the ejecting mechanism of injection mold, comprise the face needle plate, be fixed on end needle plate, the push rod of face needle plate lower surface, has the hole of passing for push rod on the face needle plate, has the groove that holds the push rod bottom on end needle plate, it is characterized in that, the bottom of push rod also is provided with at least one pad, and pad is fixedly connected with push rod by screw.
2. the ejecting mechanism of injection mold as claimed in claim 1, is characterized in that, pad, push rod and end needle plate are bolted fixing.
