Abstract
The utility model relates to a push rod structure for a die-casting die. The push rod structure comprises a strip-shaped push rod body, the push rod body comprises a first end and a second end, the first end is connected with a moving die fixing plate, the second end is used for driving a product to separate from a moving die cavity, a thread hole is opened in the front end of the second end of the push rod body, an irregular block is mounted on the thread hole, threads are formed in the rod part of the irregular block and are in spiral connection with the thread hole, and an elastic cushion layer is mounted at the front end of the irregular block. The push rod structure for the die-casting die is simple in structure; by means of the irregular block of which the top end is larger than the top end of the second end in area, the push rod structure is capable of effectively helping the product to separate from a static die cavity and the moving die cavity and preventing the product staying in the static die cavity; the irregular block is convenient to demount and mount by means of the thread hole.
Description
Technical field
The utility model relates to mold parts technical field, relates in particular to a kind of for the push rod structure on die casting.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument for formed article, and this instrument is made up of various parts, and different moulds is made up of different parts, and it mainly realizes the processing of article profile by the change of institute's moulding material physical state.
Compression casting is called for short die casting, is that one is poured melted alloy liquid in pressure chamber into, with the die cavity of high speed filling steel die, and makes aluminium alloy form the casting method of foundry goods at Under Pressure Solidification.When die-casting process, generally need to adopt a quiet mould and a dynamic model, after quiet mould and dynamic model matched moulds, form workpiece cavity, then under pressure molten metal is pressed in workpiece shape chamber, obtain the workpiece of moulding after cooling.After formed product is good, in quiet mould model cavity and dynamic model die cavity, all there is certain package power in product, when die sinking, product in quiet model cavity is released product by the motive force of injection rod from quiet model cavity, and product is trapped on dynamic model die cavity completely, and will be according to the push rod of the reasonable in design of product in dynamic model die cavity, last under the effect of push rod motive force, product is ejected to dynamic model die cavity, thereby obtain product, all effects from the sound demoulding for subsidiary products of injection rod and push rod.Wherein, after mould die sinking, injection rod can be along with the motion of dynamic model to left movement, thereby product is released from quiet model cavity, product is retained in dynamic model die cavity completely, then the push rod in dynamic model again by die casting equipment pushing mechanism by releasing in driven product model cavity, finally take out workpiece.Wherein push rod just only has one by the function of releasing in driven product model cavity.
For some more complicated products; it has a dark die cavity at dynamic model face and quiet die face; when sound mould separates; although there is the motive force of injection rod to promote product; because the package power of product in quiet model cavity is too large, the motive force of injection rod often can not be released product evenly from quiet mould, causes injection rod often the clout handle of product can be inferred; and product is still stayed in quiet model cavity, cause mould to need counterdie maintenance.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of for the push rod structure on die casting.
The utility model is to be achieved through the following technical solutions:
A kind of for the push rod structure on die casting, comprise the push rod body of a strip, on described push rod body, there is a first end being connected with dynamic mould fixing plate and second end for promoting to come off in the driven model cavity of product, the front end of the second end of described push rod body has screwed hole, on described screwed hole, special-shaped block is installed, the bar portion of described special-shaped block is provided with screw thread, is connected with screwed hole spiral, is provided with elastic insert at the front end of special-shaped block.
As optimal technical scheme of the present utility model, the apex area of described special-shaped block is greater than the area on the second end top of push rod body.
As optimal technical scheme of the present utility model, described special-shaped block there are the two oblique wings.
As optimal technical scheme of the present utility model, described push rod body is identical with the material of special-shaped block.
As optimal technical scheme of the present utility model, the thickness of described elastic insert is 5-8mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, by being provided with special-shaped block, the area on special-shaped block top is greater than the apex area of the second end, subsidiary products, from the demoulding in quiet model cavity and dynamic model die cavity, avoids product to be trapped in quiet model cavity effectively; Owing to being provided with screwed hole, make special-shaped block be convenient to remove and install simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-push rod body; 2-first end; 3-the second end; 4-screwed hole; 5-special-shaped block; 6-elastic insert.
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 for the push rod structure on die casting, comprise the push rod body 1 of a strip, on described push rod body 1, there is a first end being connected with dynamic mould fixing plate 2 and second end 3 for promoting to come off in the driven model cavity of product, the front end of the second end 3 of described push rod body 1 has screwed hole 4, on described screwed hole 4, special-shaped block 5 is installed, described special-shaped block 5 there are the two oblique wings, described push rod body 1 is identical with the material of special-shaped block 5.The bar portion of described special-shaped block 5 is provided with screw thread, is connected with screwed hole 4 spirals, is provided with elastic insert 6 at the front end of special-shaped block 5.
The apex area of described special-shaped block 5 is greater than the area on the second end 3 tops of push rod body 1, under the effect of same large power, owing to having increased contact area, has reduced pressure.
The thickness of described elastic insert 6 is 5-8mm, and the object that elastic insert is set is in order effectively to alleviate impulsive force.
The utility model is simple in structure, and by being provided with special-shaped block, the area on special-shaped block top is greater than the apex area of the second end, and subsidiary products, from the demoulding in quiet model cavity and dynamic model die cavity, avoids product to be trapped in quiet model cavity effectively; Owing to being provided with screwed hole, make special-shaped block be convenient to remove and install simultaneously.
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.
