Abstract
The utility model relates to a push rod for a metal die-casting mould. The push rod comprises a base rod, a middle rod, and a top rod, wherein a wedge block is arranged at the top end of the top rod, the inner side of the wedge block is arc-shaped, the area of the outer end of the wedge block is larger than the area of the inner end of the wedge block, a thread hole is formed in the middle rod, the tail end of the top rod is provided with a thread section, and the top rod is in thread connection with the middle rod. The push rod is simple in structure and reasonable in design, the push rod which is originally integrated is divided into three sections, and only the top rod is required to be replaced when the wedge block at the top rod is damaged; as the top rod is in threaded connection with the middle rod, the top rod and the middle rod are convenient to mount, dismount and replace; by means of the wedge block, pouring gate excess materials in the die-casting mould can slip out from a sprue bush, and the push rod has the advantages of being small in sliding resistance and difficult to clamp.
Description
Technical field
The utility model relates to die cast metal forming field, relates in particular to a kind of push rod for metal crimp mold.
Background technology
Die cast metal moulding be by the molten metal of melting under higher pressure, at full speed be packed into compression mod die cavity, and molten metal is solidified under high pressure conditions and form the process of metal crimp foundry goods, it is most effective one in current all metal casting forming methods.Along with the development of die cast metal moulding, the punch forming of die cast metal forming technique and injection-moulding plastic, metallic plate is listed as three large moulding systems.The distinguishing feature of die cast metal moulding is: can forming shape complexity, non-ferrous metal structural member that wall is thin, and be a kind of high efficiency, high accuracy, high interchangeability, low consumed precision component forming technique.Die casting machine is one of key element the most basic in Die Casting, metal crimp mold is to realize die cast by the operation of die casting machine, kind and the model of die casting machine are a lot, in general, can be divided into heat pressing type die casting machine and cold pressure die-casting machine according to the state of temperature of compression chamber of die casting machine, cold pressure die-casting machine is divided into vertical die-casting machine, full-vertical die casting machine and horizontal plunger die casting machine according to its version again.
Molten metal is in mold cavity after cooling curing moulding, due to reasons such as moulding contractions, die casting can pack tightly the surface at forming part to some extent, make the mechanism that die casting is deviate from from mould become ejecting mechanism, existing is mainly with push rod for die casting is released from mould, commercially available push-off pin is integrated at present, like this, eject damaged on end bad time when holding capacity, whole push rod all needs to change, in the middle of invisible, increased cost, existing push rod is mostly counted as cylindrical simultaneously, can not meet some special occasion.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of push rod for metal crimp mold.
The utility model is to be achieved through the following technical solutions:
For a push rod for metal crimp mold, comprise bottom bar, intermediate bar, push rod, the top of described push rod is provided with wedge, and the inner side of described wedge is circular arc, and outer end area is greater than its inner area; On intermediate bar, offer screwed hole, the end of described push rod is provided with thread segment, and push rod is threaded with intermediate bar.
As optimal technical scheme of the present utility model, described screwed hole is full thread hole.
As optimal technical scheme of the present utility model, described bottom bar, intermediate bar, push rod adopt identical material to make.
As optimal technical scheme of the present utility model, the hardness of described wedge is greater than the hardness of push rod.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, originally the push rod being wholely set is divided into three sections, in the time that the wedge on push rod damages, only need to change push rod, due to push rod and intermediate bar employing be to be threaded, be convenient to dismounting and replacing, wedge can be deviate from the running channel clout in compression mod from sprue bush, has the advantages that resistance to sliding is little, be difficult for clamping stagnation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-bottom bar; 2-intermediate bar; 3-push rod; 4-wedge; 5-screwed hole; 6-thread segment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of push rod for metal crimp mold, comprises bottom bar 1, intermediate bar 2, push rod 3, and the top of described push rod 3 is provided with wedge 4, and the inner side of described wedge 4 is circular arc, and outer end area is greater than its inner area; On intermediate bar 2, offer screwed hole 5, described screwed hole 5 is full thread hole, and the end of described push rod 3 is provided with thread segment 6, and push rod 3 is threaded with intermediate bar 2.Originally the push rod being wholely set is divided into three sections, in the time that wedge on push rod damages, only need to changes push rod, due to push rod and intermediate bar employing be to be threaded, be convenient to dismounting and replacing, reduced cost.
Described bottom bar 1, intermediate bar 2, push rod 3 adopt identical material to make, and the hardness of described wedge 4 is greater than the hardness of push rod 3, improve the service life of wedge.
Wedge 4 can be deviate from the running channel clout in compression mod from sprue bush, has the advantages that resistance to sliding is little, be difficult for clamping stagnation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
