Abstract
Provided is a mold guide device which comprises a guide hole (2) in a mold body (1). A copper sleeve (3) is arranged in the guide hole (2). Compared with the prior art, due to the fact that the copper sleeve is arranged in the guide hole, the mold guide device enables a guide post to be connected with the copper sleeve in a sliding mode; due to the fact that copper has tough and abrasion resistant characteristics and also has a certain lubricating function, when the guide post is connected with the copper sleeve in the sliding mode, a stuck phenomenon is not prone to be produced, abrasion does not easily occur, further mold combined precision in mold combination is guaranteed, and the finished product rate in production is improved; and meanwhile a seizure phenomenon does not easily occur, accordingly the phenomenon of mold damage or cracking can not occur, and therefore production continuity and stability are good, and service life of a mold is long.
Description
Technical field
The utility model belongs to the die apparatus field, particularly relates to a kind of mould guider.
Background technology
At present, the mould guider of prior art comprises guide pillar and pilot hole, but because guide pillar and pilot hole are steel or made of iron, then when guide pillar slides in pilot hole, the situation that the easy appearance each other of guide pillar and pilot hole stagnates, thereby cause the wearing and tearing of guide pillar or pilot hole more serious, and then cause the mould closing precision relatively poor, the finished product rate is lower; Simultaneously the situation of killing appears again in guide pillar and pilot hole easily, easily causes mould to damage or the situation of cracking, thereby so that produces and interrupt or situation generation that mould is scrapped.Therefore there is serious wear in the mould guider of prior art, the problem of killing easily.
The utility model content
The utility model provides a kind of not easy to wear and mould guider of killing for above problem.
The utility model overcomes the above problems used technical scheme: a kind of mould guider with following structure is provided, and it comprises the pilot hole that is located on the die ontology, is provided with copper sheathing in the described pilot hole.
After adopting above structure, compared with prior art, the utility model so that lead and copper sheathing are slidingly connected, then has extremely tough and tensile and anti abrasive characteristic because of copper self because pilot hole is provided with copper sheathing, and also has certain self-lubricating function, so can be so that guide pillar and copper sheathing when being slidingly connected, be prone to stagnant situation, not easy to wear yet, and then the closing precision when guaranteeing the mould matched moulds, improve the yield rate when producing; Be not prone to simultaneously the situation of killing yet, then just can not occur the situation that mould damages or ftractures yet, thereby so that the stability of producing is all better, and die life is also longer.
As improvement, described copper sheathing is provided with several through holes radially, all be filled with graphite in the described through hole, then because graphite has good lubrication, so that copper sheathing or guide pillar more are not prone to the situation of wearing and tearing, can further improve the stability that mould is produced, and further prolong the mold use life-span.
As preferably, described pilot hole is stepped hole, described stepped hole is divided into macropore and aperture, the axial length of macropore is less than the axial length of aperture, the external diameter of described copper sheathing equals the aperture of pilot hole aperture, and an end outer circumference surface proximal end face position of copper sheathing is provided with annular protrusion, one end end face of described annular protrusion is concordant with copper sheathing one end end face, the external diameter of annular protrusion equals the aperture of pilot hole macropore, and the axial length of annular protrusion is equal to or less than the axial length of pilot hole macropore.
Description of drawings
Fig. 1 is the structural representation of the utility model mould guider.
Fig. 2 is the structural representation of the utility model mould guider copper sheathing.
As shown in the figure: 1, die ontology, 2, pilot hole, 3, copper sheathing, 4, through hole, 5, graphite.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of mould guider as depicted in figs. 1 and 2, it comprises the pilot hole 2 that is located on the die ontology 1, is provided with copper sheathing 3 in the described pilot hole 2.
Described pilot hole 2 is stepped hole, described stepped hole is divided into macropore and aperture, being pilot hole 2 is comprised of the hole of wide-aperture hole and small-bore, the axial length of macropore is less than the axial length of aperture, the axial length in general hole, large aperture is much smaller than the axial length in hole, small-bore, the external diameter of described copper sheathing 3 equals the aperture of pilot hole 2 apertures, and an end outer circumference surface close end position of copper sheathing 3 is provided with annular protrusion, one end end face of described annular protrusion is concordant with copper sheathing 3 one end end faces, the external diameter of annular protrusion equals the aperture of pilot hole 2 macropores, and the axial length of annular protrusion is equal to or less than, and (this example is for equaling, also can for less than) axial length of pilot hole 2 macropores, to guarantee the closing precision of mould.
Described copper sheathing 3 is provided with several through holes 4 radially, the described through hole 4 interior graphite 5 that all are filled with.
Above embodiment only is preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly changes in the utility model rights to independence claimed range, all belongs to the utility model protection domain.
