Abstract
The utility model belongs to the technical field of the mould, concretely relates to pull rod. The thread guide device comprises a main rod, a first fixed end arranged at one end of the main rod, a connecting end arranged at the other end of the main rod in sequence, a second fixed end and a guide end, wherein the surfaces of the first fixed end and the second fixed end are provided with screw threads, the surfaces of the main rod, the connecting end and the guide end are smooth, and the length of the guide end is 30-50 mm. The utility model has the advantages of simple structure, the invalid length of idle running when locking pull rod screw thread changes short, cancels invalid work, and the surface of mobile jib, link and leading end is smooth to reduce the remodelling time, thereby reduce extravagantly, promote retooling efficiency.
Description
Technical Field
The utility model belongs to the technical field of the mould, concretely relates to pull rod.
Background
The pull rod is a connecting rod for connecting the die-casting machine table ejection mechanism and the die ejection mechanism, one end of the pull rod is fixed on the ejector pin bottom plate of the die, and the other end of the pull rod is fixed on the ejection panel of the die-casting machine, so that ejection and demolding effects after the product is formed are achieved. The existing pull rod has too long tail end screw threads and long screw length of a nut, and certain time is wasted in the operation process.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects and shortcomings existing in the prior art, the utility model aims to provide a pull rod.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a pull rod, includes the mobile jib, sets up in the first stiff end of mobile jib one end, sets gradually in the link of the mobile jib other end, second stiff end and leading end, and the first stiff end of telling and second stiff end surface are equipped with the thread, the surface of mobile jib, link and leading end is smooth.
Further, mobile jib, first stiff end, link, second stiff end and leading end integrated into one piece.
Further, the length of the leading end is 30-50 mm.
Further, the diameter of the cross section of the connecting end is the same as that of the cross section of the second fixing end.
Further, the diameter of the cross section of the second fixed end is larger than that of the cross section of the leading end.
The beneficial effects of the utility model reside in that: the utility model has the advantages of simple structure, the invalid length of idle running when locking pull rod screw thread shortens, cancels invalid work, and the surface of mobile jib, link and leading end is smooth to reduce the remodel time, thereby reduce extravagantly, promote retooling efficiency.

Fig. 1 is a cross-sectional view of the tie rod of the present invention.
Reference numerals:
1-a main rod; 2-a first fixed end; 3-connecting the ends;
4-a second fixed end; 5-leading end.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Referring to fig. 1, the object of the present invention is achieved by the following technical solutions: the utility model provides a pull rod, includes mobile jib 1, sets up in the first stiff end 2 of mobile jib 1 one end, sets gradually in the link 3 of the mobile jib 1 other end, second stiff end 4 and leading end 5, and the first stiff end 2 of telling and the 4 surfaces of second stiff end are equipped with the thread, the surface of mobile jib 1, link 3 and leading end 5 is smooth, the length of leading end 5 is 30-50 mm.
The utility model has the advantages of simple structure, the invalid length of idle running when locking pull rod screw thread changes short, cancels invalid work, and the surface of mobile jib, link and leading end is smooth to reduce the remodelling time, thereby reduce extravagantly, promote retooling efficiency.
Further, the main rod 1, the first fixing end 2, the connecting end 3, the second fixing end 4 and the guiding end 5 are integrally formed.
The utility model discloses a cross integrated into one piece mobile jib 1, first stiff end 2, link 3, second stiff end 4 and leading end 5, make the pull rod more durable on the one hand, each part kneck of on the other hand is more smooth.
Further, the diameter of the cross section of the connecting end 3 is the same as that of the cross section of the second fixing end 4.
Further, the diameter of the cross section of the second fixed end 4 is slightly larger than that of the cross section of the leading end 5.
This practicality sets up the straight warp with 4 cross sections of second stiff end into slightly being greater than the straight warp of 5 cross sections of leading end more conveniently guides the mobile jib motion, practices thrift the repacking time, improves work efficiency.
The above-mentioned embodiment is the utility model discloses the implementation of preferred, in addition, the utility model discloses can also realize by other modes, not deviating from the utility model discloses any obvious replacement is all within the protection scope under the prerequisite of design.
