Abstract

The utility model discloses a high-precision location device for upper dies and lower dies, which comprises an upper die, a lower die and a location plate, wherein the lower end of the location plate is respectively fixed on two sides of a lower die plane in the Y-shaft direction, a guide slot is respectively arranged on the position which is arranged on the upper die and corresponds to the location plate, the guide slot matches with the upper portion of the location plate in a sliding mode, a trapezoidal sink groove is arranged on a contact plane of the lower die and the upper die in the X-shaft direction, a trapezoidal boss is arranged on the contact plane of the upper die and the lower die, and the trapezoidal boss can be just clipped in the trapezoidal sink groove of the lower die. As the location device respectively matches with the trapezoidal sink groove through a guide plate, the guide slot and the trapezoidal boss on a matching face of the upper die and the lower die along two directions of the X-shaft and the Y-shaft, the location device guarantees upper dies and lower dies to accurately locate in X-shaft and Y-shaft directions, and walls of products after production have even thickness. Furthermore, the matching mode of the trapezoidal boss and the trapezoidal sink groove enables the upper die and the lower die to be interlocked in a single direction, the dislocation of dies is small in left and right directions, and the interlocking inclined plane has good durability and intensity.

Description

The upper die and lower die high-precision positioner

Technical field

The utility model relates to a kind of plastic mould, particularly relates to a kind of upper die and lower die high-precision positioner.

Background technology

Plastic products all a large amount of use in daily life and in the industrial products.Some industrial products have the requirement of very high precision to the wall thickness uniformity of product, as, electricity-saving lamp capacitor shell, family expenses capacitor shell, automotive-type capacitor shell, industrial relay shell etc., in order to guarantee the unanimity of housing wall thickness, core and die cavity are wanted high accuracy and accurate centering when requiring upper and lower mould matched moulds, and this has proposed higher requirement to injection mold.Common mould uses guide pillar, guide pin bushing as positioner more, but often mould produced live in guide pillar, guide pin bushing locate precisely inadequately, cause the product accuracy of alignment of producing defective.On the other hand because guide pillar, guide pin bushing are easy to wear, changes comparatively frequent and loaded down with trivial details, inconvenience in the operation, also can so and descend die life.

The utility model content

The purpose of this utility model be to provide a kind of accuracy of alignment height, not easy to wear, change convenient and can improve the upper die and lower die high-precision positioner of die life.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of upper die and lower die high-precision positioner, and it comprises upper die and lower die, location-plate; Described location-plate has two, its lower end is separately fixed at the both sides of counterdie plane Y direction, on position corresponding on the patrix, offer gathering sill respectively with location-plate, the top of this gathering sill and location-plate is slidingly matched, can allow location-plate slip into, limit the relative changing of the relative positions of upper die and lower die in X-direction; On the X-direction of counterdie and patrix contact plane, offer mouthful big, the little trapezoidal deep gouge in the end, be provided with the trapezoid boss that the top is little, the bottom is big on patrix and plane that counterdie contacts, this trapezoid boss can just in time snap in the trapezoidal deep gouge of counterdie and limit the relative changing of the relative positions of upper die and lower die in Y direction.

Described patrix mainly is made up of die cavity backing plate and cavity plate; Described die cavity backing plate and cavity plate are fixed together, and offer gathering sill respectively on the die cavity backing plate position corresponding with location-plate, and wear-resisting location mold insert is installed respectively on the two side of this gathering sill; On cavity plate and plane that counterdie contacts, be provided with the trapezoid boss that the top is little, the bottom is big.

Described counterdie mainly is made up of push pedal, fixed head, backing plate; Described push pedal, fixed head, backing plate are superimposed in regular turn to be fixed together; Fix a location-plate respectively in the both sides of backing plate Y direction; On the X-direction of push pedal and patrix contact plane, offer mouthful big, the little trapezoidal deep gouge in the end.

After adopting such scheme, because the utility model cooperates with trapezoidal deep gouge with gathering sill, trapezoid boss by guide plate respectively on upper and lower mould mating surface upper edge X-axis, Y-axis both direction, guaranteed upper and lower mould X-axis, Y direction location accurately, the product wall thickness of producing is even.And, adopt trapezoid boss and trapezoidal deep gouge fit system to make upper and lower mould folk prescription to interlocking, the mould left and right directions misplaces little, and the durability on interlocking inclined-plane, intensity are good.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a side view of the present utility model;

Fig. 4 is the front view of the utility model push pedal.

The specific embodiment

As shown in Figure 1, the utility model is a kind of upper die and lower die high-precision positioner, and it comprises patrix 1, counterdie 2, location-plate 3.

Described counterdie 2 mainly is made up of push pedal 21, fixed head 22, backing plate 23; Described push pedal 21, fixed head 22, backing plate 23 is superimposed in regular turn is fixed together; Both sides in the Y direction of backing plate 23 are fixed a location-plate 3 (location-plate 3 has two) respectively; On the X-direction of push pedal 21 and patrix 1 cavity plate 12 contact planes, offer mouthful big, the little trapezoidal deep gouge 211 (as shown in Figure 4) in the end.

Described patrix 1 mainly is made up of die cavity backing plate 11 and cavity plate 12.Described die cavity backing plate 11 is fixed together with cavity plate 12, offers gathering sill 111 (as shown in Figure 2) respectively on the corresponding position of die cavity backing plate 11 and location-plate 3, and location mold insert 4 wear-resisting and that be easy to change is installed respectively on the two side of this gathering sill 111; This gathering sill 111 is slidingly matched with the top of location-plate 3, can allow location-plate 3 slip into, thereby limit the relative changing of the relative positions of patrix 1 and counterdie 2 in X-direction.

Shown in Figure 4 as Fig. 3 reference, on patrix 1 cavity plate 12 and plane that counterdie 2 push pedals 21 contact, be provided with the trapezoid boss 121 that the top is little, the bottom is big, this trapezoid boss 121 can just in time snap in the trapezoidal deep gouge 211 of counterdie 2 cavity plate 12, thereby has limited the relative changing of the relative positions of patrix 1 and counterdie 2 in Y direction.

Emphasis of the present utility model just is: cooperate with trapezoidal deep gouge with gathering sill, trapezoid boss by guide plate respectively on upper and lower mould mating surface upper edge X-axis, Y-axis both direction.

The above, it only is the utility model preferred embodiment, guide plate with gathering sill, trapezoid boss not necessarily will be in X, Y direction with cooperating of trapezoidal deep gouge, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
