The utility model has the advantages that the cooling of reinforcing plate is more even while in cast; the bend and the deformation is smaller; the rigidity of the mould plate material is more even, and the intensity is better.
Description
Technical field:
The utility model relates to a kind of parts of Clamping Device of Injection Moulding Machine, specifically is the Injection Motor Template that a kind of solid plate that is installed on four pull bars with injection machine is used.
Background technology:
The moving platen of all size injection machine generally comprises the gap bridge of band mould installing hole, the template body that ejects hole and four pull bar guide holders and band tie rod holes seat in the prior art.The template body of this structure Injection Motor Template such as generally adopts at thick plate structure, and promptly as the slab of template body, its inside is solid and wall thickness equates.The weak point of thick plate structures such as employing is: 1, the material usage of casting template body is too many, moving platen manufacturing cost height; 2, the heavy wall of template body is easy to generate pore when casting, thereby makes the template body loose, and the material density unevenness is even, and the intensity of material weakens; And when matched moulds, make the moving platen discontinuity easily and weaken moving platen greatly and correct the uneven ability of mould, make die deformation inconsistent, make goods the phenomenon that overlap is burr occur; 3, be in the duty of discontinuity when moving platen for a long time, itself also can be subjected to certain wearing and tearing and shorten service life of moving platen.
Disclose the utility model patent that a kind of name is called the injection machine collapsible form on the China national Department of Intellectual Property webpage, as shown in Figure 5, it mainly is made up of outer wall 51,52,53,54, longitudinal rib 61,62 and the horizontal bar 71,72 of sealing all around; Described longitudinal rib 61,62 connects top exterior walls 51 and bottom outer wall 53; Described horizontal bar 71 connects longitudinal rib 62 and the right outer wall 52; Described horizontal bar 72 connects longitudinal rib 61 and left side outer wall 54; Middle and upper part between the described longitudinal rib 61,62 and middle and lower part also have two circular-arc horizontal bars 73,74 to connect longitudinal rib 61 and longitudinal rib 62; Also be provided with waling 81,82,83,74 between the described longitudinal rib 61,62, described waling 81,82 1 ends connect horizontal bar 73, and described waling connects horizontal bar 74; Described longitudinal rib 61,62 all is coarser than horizontal bar 71,72,73,74; Form the die cavity 101 of this utility model collapsible form between described each horizontal bar, longitudinal rib, reinforcement and each outer wall.Above-mentioned utility model is compared with existing injection machine collapsible form, its advantage just is that it has better intensity under certain thickness, stress distribution is comparatively average, can avoid die deformation inconsistent and the phenomenon of overlap occurs, and cavity structure is simple, production cost and percent defective are low.But still there are following two weak points in this utility model: 1, as shown in Figure 6, R1, R2 are free bearing among the figure, and L is a free bearing centre-to-centre spacing, and L1 is a die size, and δ is the moving platen deflection, and arrow represents to be subjected to force direction; From Fig. 6, be not difficult to find out, the flexural deformation maximum be middle part at moving platen, we can draw from general qualitative analysis in conjunction with Fig. 5, though this utility model bulk strength is than higher, but the more weak and skewness of strength ratio at its template body middle part, this is because the distribution of gusset rationally causes inadequately, so its intensity awaits further to strengthen; 2, the variable thickness of longitudinal and transverse gusset causes promptly wide, narrow differing in this utility model, and its outer wall be around enclosed type, therefore cause moving platen cooling velocity speed when casting to differ easily, moving platen hardness is weakened and intensity distributions inhomogeneous.
The utility model content:
The technical problems to be solved in the utility model is, provide a kind of keep prior art moving platen manufacturing cost and percent defective is low, die cavity simple, can avoid die deformation inconsistent and original advantage of finning appears and in, the Injection Motor Template of advantage such as gusset can evenly cool off when also having casting, template material hardness is more even, intensity is better.
Technical solution of the present utility model is to provide a kind of injection moulding machine template with following structure, the bridge plate of crossing that it comprises band mould installing hole, ejects the template body of hole and four pull bar guide holders and be with the tie rod holes seat; Described template body interior is provided with longitudinal rib, horizontal bar and waling; Described longitudinal rib is connected respectively with the horizontal bar of close top exterior walls and the horizontal bar of close bottom outer wall; Described circular-arc horizontal bar is positioned at the middle part of template body, and is connected near on the longitudinal rib in the middle of the template body; Described waling is between near the longitudinal rib in the middle of the template body and be connected on the horizontal bar near top exterior walls and bottom outer wall; It between described longitudinal rib, horizontal bar and the waling die cavity; The thickness equalization of described longitudinal rib, horizontal bar and waling.
After adopting above structure, compared with prior art, the utlity model has following advantage: the utility model is on the basis that keeps advantages such as the low and die cavity of prior art Injection Motor Template manufacturing cost and percent defective is simple, make each longitudinal rib, horizontal bar and reinforcement distribution in the Injection Motor Template become more reasonable, especially the distribution situation of moving platen middle part gusset has obtained better more reasonably design and has arranged, and intensity is better; Longitudinal rib, horizontal bar and waling adopt equal equal thickness that gusset is evenly cooled off when casting in addition, make the template material hardness of moving platen more even.Just because of these advantages also make the uneven ability of the utility model correction mould stronger, service life is also longer.
As a kind of improvement of the present utility model, the width of the die cavity between the described two adjacent muscle is greater than the thickness sum of two adjacent muscle; The width of the die cavity between described longitudinal rib or horizontal bar and the outer wall is greater than the wall thickness sum of longitudinal rib thickness or horizontal bar thickness and outer wall.This improvement speed that molding sand heats up when being subjected to heat effect that can slow down effectively is convenient to the heat radiation of muscle, avoided the generation of serious scab phenomenon, and the sand removal of foundry goods is more convenient, cleans up easily.
As two of improvement of the present utility model, the junction between described each muscle can be fillet.Adopt the fillet mode can prevent effectively that the moving platen foundry goods from cracking when shrinking.
As three of improvement of the present utility model, have some through holes on the described outer wall.Sand removal not only is convenient in the setting of through hole, and makes the cooling of moving platen foundry goods become more even.
As four of improvement of the present utility model, the middle part of the longitudinal rib of described close left side outer wall and the longitudinal rib of close the right outer wall is circular arc.The longitudinal rib of middle part circular arc makes the distribution of moving platen middle part muscle more reasonable, and the intensity at moving platen middle part is higher.
As five of improvement of the present utility model, have some small sircle holes on the floor of described template body, the setting of small sircle hole not only makes the thickness of floor be controlled by the degree of depth of small sircle hole accurately, and the core that assembles is fused, and makes the muscle in the moving platen be difficult for skew.In addition, the setting of small sircle hole also is that the sand removal work of moving platen becomes convenient.
