Description
Technical Field
The utility model relates to an injection moulding equipment field specifically is an art hand-basket lamp shade multidirectional slide block mechanism mould of loosing core.
Background
The demolding design of a complex plastic part is an inevitable difficult problem in mold design, generally speaking, the characteristic of difficult demolding on the plastic part is only the characteristic of difficult demolding of a few local areas, and when the demolding mechanism with the characteristic of difficult demolding of the local areas is designed, firstly, the demolding direction of the complex plastic part is in accordance with the barrier-free withdrawing direction of the characteristic molded part, secondly, enough mechanism space is required to meet the movement of the molded part, and the movement of the molded part is driven by the aid of the mold opening driving force of a mold frame template or an auxiliary power mechanism. The design of the die opening driving force mechanism or the auxiliary power mechanism is limited by the interference limit of other mechanism designs on the die or the structural limit of the die carrier, which is the difficult point of the design of the demoulding mechanism. Therefore, before the structural design of the mold, when the overall structure of the mold is designed according to the structural characteristics of the plastic part, on the premise of making the layout design of the mold cavity, the structural mode and the layout of the mechanism required for molding the plastic part are made, which is a key work of the structural design of the mold. The demolding of the overlapping characteristic on the plastic part is a difficulty in mold demolding mechanism and structural design, namely, on the basis that a large area needs to be subjected to lateral demolding, a local small area exists in the large area and needs to be arranged in small areas with different core pulling directions of the large area for core pulling, and under the condition that the two core pulling directions are inconsistent, core pulling for multiple times in the same large area is needed to realize core pulling demolding of the whole large area on the plastic part.
For the plastic part with the shape of the artistic basket lamp shade plastic part, in order to meet the requirement of industrial design, the appearance of the plastic part is designed into a basket form, the main body of the plastic part is in a frustum shape, and two axisymmetric circular-bent protection hooks are arranged at the upper end of the plastic part; 4 fish-shaped bulges formed by convex artistic curved surfaces are arranged on the outer wall of the frustum body and used for the industrial appearance beauty of the plastic part and the space avoidance of other parts in the cover body; 2 plug wire holes are distributed at the lower end of the outer wall of the frustum, and a boss is arranged on the outer wall of each hole; the lowest end of the outer wall is provided with a string of trademark characters which are arranged on the frustum wall of the main body.
The mold design of the artistic basket lamp shade plastic part has the following difficulties:
1) the plastic part is an irregular plastic part, has certain requirements on appearance shape and size precision, and has tolerance grade of MT4 grade;
2) two symmetrical basket protective hooks at the upper end of the plastic part are in arc shapes, and the demolding direction can only laterally loose cores from two side surfaces for demolding;
3) the 4 fish-shaped protrusions on the main body frustum are in a shape of narrow-wide-narrow when viewed from top to bottom, and the demolding direction of the protrusions can not be set to be the axial lead direction of the circular truncated cone but can only be set to be the direction perpendicular to the axial lead of the boss;
4) 2 plug wire holes at the bottom end of the outer wall of the boss can be demoulded only along the axial direction of the hole;
5) the lateral demoulding direction of the protection hook is not consistent with the axis direction of the wire inserting hole to form an included angle, so that if the core-pulling demoulding direction of the outer wall side of the theme frustum is set to be consistent with the direction of the protection hook, the wire inserting hole is positioned on the outer wall of the frustum, the demoulding direction of the wire inserting hole is crossed and interfered with the outer wall and the demoulding direction of the fish-shaped bulge, and the demoulding structure is difficult to set.
