Abstract
The invention discloses a die of a large-air-chamber high-voltage electrical appliance accessory product. The die comprises an upper die, a left die and a right die are arranged on the lower side of the upper die, a left sand core and a right sand core are arranged between the left die and the right die, a bottom die is arranged on the lower sides of the left and right sand cores, partition plates are arranged between the left sand core and the right sand core as well as among the upper die, the left die, the right die and the bottom die, and a sprue is formed in the middle of the bottom die. The die is characterized in that allowance is increased by the lower half of the partition plate between the left sand core and the right sand core and is obtained by integrally rotating a boundary, before being improved, of the lower half of the partition plate between the left sand core and the right sand core leftwards by inclination of 2.5 degrees to turn into an improved boundary, the partition plate is of a structure with the big end up, and according to a low-pressure casting operating principle, feeding from bottom to top is achieved, so that the partition plate is fed integrally sufficiently, and a final shrinkage portion is transferred into the sprue.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold.
Background technology
High-Voltage Electrical Appliances accessory atmospheric air chamber aluminium alloy castings partition part is uniform wall thickness, and due to excessive height, cast gate cannot divide to middle and upper part in feeding, and dividing plate is in again between left core and right core, solidifies comparatively slow, very easily produces shrinkage defect.
Summary of the invention
The present invention easily produces a difficult problem for shrinkage defect in order to solve High-Voltage Electrical Appliances accessory atmospheric air chamber aluminium alloy castings, and provides a kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold.
The present invention for achieving the above object, provides a kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold, comprises patrix, be provided with left mould and right mould below patrix, be provided with left core and right core between left mould and right mould, be provided with bed die below left core and right core; Left core and right core and patrix, Zuo Mo, between right mould and bed die, be provided with dividing plate; Be provided with cast gate in the middle part of bed die, it is characterized in that, the dividing plate the latter half between left core and right core adds correction amount; Described correction amount be the improvement front border of dividing plate the latter half between left core and right core overall become to improve toward anticlockwise 2.5 ° of gradients get after border afterwards.
The invention has the beneficial effects as follows: a kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold of the present invention, dividing plate the latter half is improved front border overall toward anticlockwise 2.5 ° of gradients, become border after improving, add correction amount, like this, make dividing plate form lower large little structure, by low pressure casting operation principle, achieve and carry out feeding from lower to upper, make dividing plate entirety obtain abundant feeding, last shrinkage porosite part is transferred in cast gate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold of the present invention;
Wherein: the left mould of 1-; The left core of 2-; 3-patrix; The right core of 4-; The right mould of 5-; 6-bed die; 7-dividing plate; 8-improves front border; Border after 9-improves; 10-correction amount; 11-cast gate.
Detailed description of the invention
Be described in detail with reference to accompanying drawing below with reference to embodiments of the invention.
A kind of High-Voltage Electrical Appliances accessory atmospheric air chamber product mold, comprise patrix 3, patrix 3 is provided with left mould 1 and right mould 5 below, is provided with left core 2 and right core 4 between left mould 1 and right mould 5, and left core 2 and right core 4 are provided with bed die 6 below; Left core 2 and right core 4 and patrix 3, left mould 1, between right mould 5 and bed die 6, be provided with dividing plate 7; Be provided with cast gate 11 in the middle part of bed die 6, dividing plate 7 the latter half between left core 2 and right core 4 adds correction amount 10; Described correction amount 10 be the improvement front border 8 of dividing plate 7 the latter half between left core 2 and right core 4 overall toward anticlockwise 2.5 ° of gradients become improve after get after border 9.
2.5 ° of data being through scientific algorithm and verification experimental verification and drawing, can play Feeding channel effect, the waste of minimizing aluminium material that again can be minimum.
