Abstract
The utility model relates to a three-plate mould structure capable of preventing rotation of a position-limiting pull rod, comprising a fixed mould fixing plate (6), a push plate (5) and a fixed mould plate (4), wherein a bolt fixing hole is arranged on the fixed mould fixing plate (6), a stop bolt (1) penetrates through the bolt fixing hole, one end of the stop bolt (1) is connected with the position-limiting pull rod (3) in a threaded manner, a bolt cap (10) is arranged at the other end of the stop bolt (1), a pin hole is arranged on the bolt cap (10), a pin (2) is inlaid in the pin hole, and a countersunk hole of the bolt fixing hole is provided with a pin demising groove. As the pin is inlaid on the bolt cap, the stop bolt can be prevented from rotating along with the position-limiting pull rod when the position-limiting pull rod is loosened and is then tightened in the mould opening state, thereby not only avoiding that the position-limiting pull rod can only be tightened after a mould is taken down from an injection molding machine, not also increasing the production efficiency.
Description
Technical field
The utility model belongs to the mould design and makes, and relates in particular to the three template die structures that anti-limit pull rod rotates.
Background technology
At present, often can meet the situation that needs twice-die-opening in a lot of mould designs and in making, such as the automobile electrical equipment box that uses on the automobile or fuse box upper and lower covers and some housing class plastics etc., it is not very big that these products generally have output, but die size is bigger, and can't open characteristics at die joint to cast gate.Owing to be not in enormous quantities, generally without the hot flow path technology, so just can only use the twice-die-opening mode to carry out the demoulding.And twice-die-opening must use caging bolt (dogbolt+limit pull rod), frequent in the production process owing to die sinking, the loosening phenomenon of screw in use will appear in caging bolt, not descend at mould under the situation of injection machine since rotation cause can't tighten the screws.The caging bolt of present standard component producer does not all add anti-rotation structure to caging bolt, so just have to take apart a die screw tightening from injection machine, and this will delay many times, thereby has influenced production, and efficient reduces also causes production cost to raise.
Summary of the invention
The purpose of this utility model is to solve above shortcomings in the prior art, a kind of three template die structures that anti-limit pull rod rotates that are used for are provided, at bolt looseness, mould does not descend under the situation of injection machine, not only can enhance productivity, reduce cost, and do not influence the moulding process of product, effectively guarantee product quality.For achieving the above object, the utility model adopts following technical scheme:
The three template die structures that anti-limit pull rod of the present utility model rotates, comprise cover half fixed head, push pedal and solid plate, establish the bolting hole on the cover half fixed head, dogbolt passes in fixing hole, and dogbolt one end is threaded with limit pull rod, and the other end is provided with nuts, wherein, nuts is provided with pin hole, and pin is embedded in the pin hole, and bolting hole counterbore is provided with the pin slot to make way.
Be embedded in pin on the dogbolt cap with the dogbolt axially-movable, the pin slot to make way degree of depth is consistent with the bolting hole counterbore degree of depth.
Described limit pull rod is a bolt draw bar, and the one end is provided with the internal thread hole that is connected with dogbolt, and the other end is provided with the spacing head of hexagonal counterbore in the band.
The pin slot to make way degree of depth on the cover half fixed head should be consistent with the bolting hole counterbore degree of depth.
The utility model adopts on the nuts inlays pin, and loosening at limit pull rod, die opening state is gone down when tightening limit pull rod, can prevent that dogbolt from rotating with limit pull rod.Thereby avoided mould is unloaded the phenomenon that injection machine just can be tightened limit pull rod, improved production efficiency.And fundamentally avoided influence, guaranteed product quality, reduced production cost, made product on market, have competitiveness more Shooting Technique.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation in the utility model
The specific embodiment
As shown in the figure, the three template die structures that anti-limit pull rod of the present utility model rotates, comprise cover half fixed head 6, push pedal 5 and solid plate 4, establish the bolting hole on the cover half fixed head 6, dogbolt 1 passes in the bolting hole, dogbolt 1 one ends are threaded with limit pull rod 3, the other end is provided with nuts 10, and wherein, nuts 10 is provided with pin hole, pin 2 is embedded in the pin hole, and bolting hole counterbore is provided with the pin slot to make way.
On the described cover half fixed head 4 the bolting hole is arranged, bolting hole counterbore has the pin slot to make way, and the pin slot to make way degree of depth is consistent with the bolting hole counterbore degree of depth.
Described limit pull rod 3 is a bolt draw bar, and the one end is provided with the internal thread hole that is connected with dogbolt, and the other end is provided with the spacing head of hexagonal counterbore in the band.
8 for tightening the used spanner of limit pull rod 3 among the figure, and 9 draw the material pin for what be used to draw material on the mould among the figure.
The course of work of the present utility model is: after die sinking repeatedly, limit pull rod 3 the loosening phenomenon of screw occurs with dogbolt 1 connecting portion branch, do not descend in the production of injection machine at mould, normally directly limit pull rod 3 is tightened with spanner, and limit pull rod 3 and dogbolt 1 are to do rectilinear motion with die sinking, its installation is a matched in clearance, so when turning limit pull rod 3, dogbolt 1 rotation that also will follow suit, so just can't tighten, make and exist potential safety hazard in the production process always.And after inlaying anti-rotation pin 2 on the dogbolt cap, just this phenomenon can not appear, when tightening limit pull rod 3, dogbolt 1 can not followed together and rotate, so just realized that need not unload injection machine to mould just can tighten limit pull rod, guaranteed production efficiency, eliminated potential safety hazard.
