The mould of base station unit
Technical field
The present invention relates to a kind of mould, especially relate to a kind of mould that is used to make the base station unit of high-performance PHS base station shell.
Background technology
Along with communication traffic in recent years develop rapidly, the requirement of people's communication network ability is more and more higher, but integrated service electrical equipment base station system as its network transmission, international and domestic market just at present, problem such as the ubiquity base station power is little, reception information instability, traffic rating are low.Wherein the capacity of base station system is low, power is little, is one of key that has problems.
The high-power base station electric equipment that is used for Personal Handyphone System communication network transmission system, since its precision parts technical indicator height, present domestic other manufacturers that still do not have, and the domestic market is almost captured by overseas enterprises such as MITs.Even like this, present stage is also relatively poor in its conduction transmission property of the PHS base station that uses, and precision is not high, and resistance to saltfog is also relatively poor with attached property.
Summary of the invention
The present invention mainly is that its conduction transmission property of solution existing in prior technology PHS base station is relatively poor, precision is not high, resistance to saltfog and the technical problem of attached property difference etc., provide a kind of conduction transmission property of producing better, high precision, resistance to saltfog are better and the mould of the base station unit of the attached property of brilliant idea base station.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the mould of base station unit, comprise fixed half and moving half, and the die cavity that forms by the fixed half and moving half cooperation, it is characterized in that: described cover half is provided with barrel and casting gate, described casting gate is located at cover half Lower Half left side, and barrel communicates with casting gate, and described dynamic model is provided with exhaust outlet, and described exhaust outlet and casting port position are on same aspect.Casting gate is located on the parallel radiating ribs, and casting gate adopts and to account for 3/4ths of feed end width, adopts outer shoulder formula to discharge vortex near casting port position, and the cinder ladle gross weight reaches 15% of product weight, thereby helps exhaust, minimizing pore and cold burden.
As preferably, the cover half of described die cavity top is provided with fin and inserts, and described fin is inserted and is horizontally set.Fin is inserted is provided with direction and liquid materials flow to consistent, in the forming process of product, makes that the Density Distribution of product is comparatively even, and helps exhaust.
As preferably, described dynamic model is provided with the post position, and top, described post position is positioned at the center-right position of die cavity.Post is provided with for the needs of product structure.
As preferably, the cover half of the relative side of described casting gate is provided with slide block, and the described slide block outside is provided with coupled Angle Pin.By the control of Angle Pin, make things convenient for the taking-up of shaped article in the mould to slide block.
As preferably, be provided with current divider below the described barrel.
As preferably, the dynamic model in the described die cavity outside is provided with fluid passage.Fluid passage is arranged on the dynamic model in the die cavity outside, makes entire die religion is set for compact, convenient production.
As preferably, the right side of described dynamic model bottom is provided with blade-turning guide pillar.Help the taking-up of shaped article in the mould.
Therefore, the present invention has following characteristics: 1. and simple in structure, be provided with rationally; 2. conduction transmission property is better, and precision is higher, and resistance to saltfog is better; 3. adopt outer shoulder formula to discharge vortex near casting port position, the cinder ladle gross weight reaches 15% of product weight, helps exhaust, makes pore and cold burden significantly reduce; 4. by not putting the blade-turning guide pillar that Angle Pin is provided with the control of slide block and dynamic model bottom, shaped article is very convenient from the taking-up in the mould.

Accompanying drawing 2 is a kind of cover half structural representations of the present invention;
Accompanying drawing 3 is a kind of dynamic model structural representations of the present invention.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment 1: the mould of base station unit, comprise cover half 1 and dynamic model 2, cover half 1 and dynamic model 2 cooperate formation one die cavity 3 up and down, cover half 1 is provided with barrel 11, be provided with a current divider 6 (referring to accompanying drawing 1) in the barrel 11, be provided with casting gate 12 near barrel 11 places, casting gate 12 communicates with barrel 11, the central area of cover half 1 is a rectangle and recessed, be provided with exhaust outlet 13 around the following recess end face, recessed bottom surface is provided with fin and inserts 14, the distance that each fin is inserted between 14 is identical, and the periphery of concave region and close barrel 1 place are provided with 2 triangular shape projections 9 (referring to accompanying drawing 2), are provided with Angle Pin 5 on the cover half 1 and with a relative side place of barrel 11, Angle Pin 5 limits are provided with slide block 4, and Angle Pin 5 links together with slide block 4.Be equipped with an aperture 9 on four angles of cover half 1.The central area of dynamic model 2 is an epirelief, and matches with the center of cover half 1, is provided with fluid passage 7 around the last convex domain, is provided with 4 in the last convex domain and is distributed in diverse location and post position 21 that extend downwards, and the right side of dynamic model 2 bottoms is provided with blade-turning guide pillar 8.Four angles of dynamic model 2 are provided with the bolt 10 (referring to accompanying drawing 3) that matches with aperture 9 diameters.
During use, cover half 1 and dynamic model 2 are worked good up and down, and the molten metal material is injected barrel 11, the liquid material injects die cavity 3 through casting gate 12 again by barrel 11, after the liquid material filled up die cavity 3, under the effect of pressure, the gas that is blended in the liquid material was discharged through exhaust outlet 13, the blank of making has intensity preferably, after the cooling, drive blade-turning guide pillar 8 motions, dynamic model 2 moves downward, pulling Angle Pin 5 makes slide block 4 outwards move, and takes out finished product just then.
