Description

Multidirectional core-pulling half slide block mechanism die of artistic basket lampshade
Technical Field
The invention relates to the field of injection molding equipment, in particular to a multidirectional core-pulling half slide block mechanism die of an artistic basket lampshade.
Background
The demolding design of complex plastic parts is a difficult problem to be encountered in mold design, in general, the features of difficult demolding on plastic parts are only difficult demolding of few local area features, and when the demolding mechanism of the local area difficult demolding features is designed, firstly, the demolding direction of the demolding mechanism should be in compliance with the barrier-free extraction direction of the feature molded parts, and secondly, enough mechanism space is needed to meet the movement of the molded parts, and the movement of the molded parts needs to be driven by means of the mold opening driving force or auxiliary driving force mechanism of the mold frame template. The design of the mold opening driving force mechanism or the auxiliary power mechanism is limited by interference limitation of other mechanism designs on the mold or structural limitation of the mold frame, which is the design difficulty of the demolding mechanism. Therefore, before the structural design of the mold, the structural mode and layout of the mechanism required by molding the mold are firstly made on the premise of making the layout design of the mold cavity when the structural design of the overall structure of the mold is carried out according to the structural characteristics of the mold, which is an important work of the structural design of the mold. The demolding of the overlapping characteristic on the plastic part is a difficult point in the mold demolding mechanism and the structural design, namely, on the basis that a large area needs to be laterally demolded on the plastic part, a small area which is partially in the large area needs to be set in a small area with different core-pulling directions in the large area to core, and under the condition that the two core-pulling directions are inconsistent, the core-pulling demolding of the whole large area on the plastic part can be realized only by repeatedly carrying out core-pulling in the same large area, and the mechanism mainly interferes in the core-pulling direction of the molded part and the driving machine component in space from the setting of the molded part, so that the failure of the structural design of the whole pair of molds is easy to cause.
For the plastic part in the shape of the artistic basket lampshade, the shape of the plastic part is designed into a basket form in order to meet the needs of industrial design, the main body of the plastic part is in a frustum shape, and two axisymmetric round bent guard 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 are used for the industrial appearance beauty of plastic parts 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 bosses are arranged on the outer wall of the holes; the lowest end of the outer wall is provided with a string of trademark characters, and the characters are arranged on the frustum wall of the main body.
The mould design of the artistic basket lampshade plastic part has the following difficulties:
1) The plastic part is irregularly shaped, has certain appearance shape requirements and dimensional accuracy control requirements, and has a tolerance level controlled to be MT4 level;
2) The two symmetrical basket hooks at the upper end of the plastic part are arc-shaped, and the demolding direction of the basket hooks can only be used for laterally pulling cores from two side surfaces for demolding;
3) The 4 fish-shaped bulges on the main body frustum are in a narrow-wide-narrow shape when seen from top to bottom, and the demoulding direction cannot be set to the axial line direction of the round table, but only to the direction perpendicular to the axial line of the boss;
4) The 2 plug wire holes at the bottom end of the outer wall of the boss can only be demoulded along the axial direction of the hole;
5) The side demoulding direction of the protective hook is inconsistent with the axis direction of the plug wire hole to form an included angle, so if the outer wall side core pulling demoulding direction of the subject frustum is set to be consistent with the direction of the protective hook, the plug wire hole is positioned on the outer wall of the frustum, the demoulding direction of the plug wire hole is intersected with the demoulding direction of the outer wall and the fish-shaped bulge to interfere, and the demoulding structure is difficult to set.
