The centerline collineation of line and cover half template transverse direction, center line and the cover half template longitudinal direction of longitudinal two positioning mother tuber length direction
Centerline collineation；The public block of four positioning is respectively set on the central cross line of the dynamic model template, wherein laterally two positioning
The center line in public block length direction and the centerline collineation of dynamic model template transverse direction, longitudinal two position the center in public block length direction
Line is conllinear with the longitudinally central line of dynamic model template；The median plane and corresponding positioning mother tuber in the positioning public block length direction are long
The median plane for spending direction is coplanar.
Further, the trapezoidal groove size of the positioning mother tuber is matched with the trapezoid boss size for positioning public block.
Further, the guide post guide sleeve component includes guide pillars and bushes, and there are four the guide sleeves, is separately mounted to
On four angles of cover half template；There are four the guide posts, is separately mounted on four angles of dynamic model template；In the guide post
Mandrel line and conllinear with corresponding guide sleeve central axis.
Further, clearance fit between the guide post and guide sleeve.
Further, total is symmetrical, symmetrical about longitudinal centre line about cross central line.
Further, the guide post is cylindrical guides, and the guide sleeve is cylindrical guide sleeve.
Compared with prior art, the invention has the following advantages:
The utility model uses the rational deployment of contour localization block assembly centerline collineation two-by-two, avoids because of temperature difference
Contour localization block assembly inordinate wear, considerably increases contour localization block assembly service life, can keep entire caused by different
The permanent effect of mold positioning accuracy has very big help to product quality is improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (die opening state) of the utility model.
Fig. 2 is the right side view of the cover half template of the utility model.
In figure: 1, guide sleeve, 2, cover half template, 3, positioning mother tuber, 4, guide post, 5, the public block of positioning, 6, dynamic model template, 7, type core
Component.
Specific embodiment
The present invention is further described through with reference to the accompanying drawing.As shown in Figs. 1-2, a kind of plastic product forming mold
Dynamic model cover half location structure, including cover half template 2, core package 7, contour localization block assembly, dynamic model template 6 and guide post guide sleeve
Component, the core package 7 are installed on the center of cover half template 2, and the contour localization block assembly includes positioning 3 He of mother tuber
Position public block 5；Four positioning mother tubers 3 are respectively set on the central cross line of the cover half template 2, wherein laterally two positioning
The lateral centerline collineation of the center line and cover half template 2 of 3 length direction of mother tuber, longitudinal two positioning, 3 length direction of mother tuber
Center line is conllinear with the longitudinally central line of cover half template 2；Four are respectively set on the central cross line of the dynamic model template 6 to determine
The public block 5 in position, wherein laterally two center lines for positioning 5 length direction of public block and the centerline collineation that dynamic model template 6 is lateral, longitudinal
Two center lines for positioning 5 length direction of public block are conllinear with the longitudinally central line of dynamic model template 6；5 length of positioning public affairs block
The median plane in direction is coplanar with the median plane of corresponding positioning 3 length direction of mother tuber.
Further, the trapezoidal groove size of the positioning mother tuber 3 is matched with the trapezoid boss size for positioning public block 5.
Further, the guide post guide sleeve component includes guide post 4 and guide sleeve 1, and there are four the guide sleeves 1, pacifies respectively
On four angles of cover half template 2；There are four the guide posts 4, is separately mounted on four angles of dynamic model template 6；It is described
4 central axis of guide post and conllinear with corresponding 1 central axis of guide sleeve.
Further, clearance fit between the guide post 4 and guide sleeve 1.
Further, total is symmetrical, symmetrical about longitudinal centre line about cross central line.
Further, the guide post 4 is cylindrical guides, and the guide sleeve 1 is cylindrical guide sleeve.
The working principle of the utility model is as follows:
In production scene, the case where for part mould contour localization block assembly quick abrasion, the analysis of causes is carried out, it is final to send out
Existing this kind of mold has a general character in use, be exactly dynamic model cover half cooling temperature it is variant.Further analysis, discovery
Between dynamic model and cover half if when temperature difference is larger, the swell increment of 2 two sides of dynamic model template 6 and cover half template is different, this
Sample results in dynamic model template 6, and both direction is each in length and breadth for distance and cover half template 2 between the public block 5 of each two positioning of both direction in length and breadth
The distance between two positioning mother tubers 3 difference, since each two contour localization block assemblies of both direction are parallel cloth in length and breadth originally
It sets, i.e., the center line of two contour localization block assembly length directions is parallel, if temperature difference between dynamic model and cover half
Less, then the distance between public block 5 of two positioning on dynamic model template 6 and two positioning mother tubers 3 on corresponding cover half template 2
The distance between be not much different, conversely, then differ larger, mold is caused to position public block 5 and positioning mother tuber 3 in clamping process
Side friction aggravates, and so as to cause contour localization block assembly serious wear, shortens contour localization block assembly service life.
The parallel arrangement of each two contour localization block assemblies of both direction in length and breadth is changed to center line two-by-two by the utility model
Conllinear layout type, since the position of center line will not be influenced by temperature difference, it is ensured that position public block 5 and positioning mother tuber
3 center line always in the same horizontal plane (being reference with orientation shown in FIG. 1), thus can be to avoid the public block 5 of positioning
It is this to be laid out the function of not only having met positioning with the unbalanced friction between positioning mother tuber 3, but also can be led to avoid because of temperature difference
The molding inordinate wear of cause.
The present invention is not limited to the present embodiment, any equivalent concepts within the technical scope of the present disclosure or changes
Become, is classified as protection scope of the present invention.
