If this air duct board carries out extrusion molding production using PVC raw materials, production difficulty is larger, easily occurs raw material missing on finished product and causes
Hole, especially in reinforcement part, and bubble is easily mixed into the plastics melted during formed product, influences into quality
Amount.
Utility model content
Technical problem to be solved in the utility model is：A kind of squeezing for the good PVC inlet vent of bus plates of Forming Quality is provided
Mould.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of PVC inlet vent of bus plate squeezes
Mould, including distributary division, forming part, the discharging portion to link together, forming part include anterior shaping mould, middle part shaping mould,
The extrusion molding notch being engaged with air duct board cross-sectional shape is designed with rear portion shaping mould, anterior shaping mould and middle part shaping mould, after
The extruding groove gradually tapered up along feed direction is provided with portion's shaping mould, extruding groove charging side is consistent with extrusion molding notch profile, squeezes
It is consistent with air duct board cross-sectional shape to go out groove discharging side, is provided with shaping core in the shaping mould of middle part in extrusion cavities, is molded core
Discharging side extend the discharging end of discharging portion, the charging side for being molded core extends the charging end face of anterior shaping mould
Place, shaping core is provided with charging one end draws material inclined-plane, and shaping core is provided with shaping at the reinforcement corresponding to air duct board and lacked
Mouthful, shaping core is provided with the injection through hole that diameter is more than shaped notch width in shaped notch bottom；It is provided with distributary division with squeezing
Portal the split channel being connected, and split channel width gradually increases to, shunting consistent with extrusion molding width of rebate along feed direction
Passage top discharge section is provided with contraction section of the height no more than its feed zone height 2/3；Discharging portion is provided with and air duct board cross-sectional shape
Consistent discharge opening, distributary division are provided with the injection die orifice being connected with extruder body, and injection die orifice is provided with to be led to shunting
The charging hole that road is connected.
As a kind of preferable scheme, the distributary division, forming part, discharging portion periphery be designed with some temperature it is adjustable plus
Hot plate.
The beneficial effects of the utility model are：Draw material inclined-plane because shaping core is provided with charging one end so that material energy
More swimmingly enter extrusion molding notch；Because shaping core is provided with shaped notch, forming core at the reinforcement corresponding to air duct board
Mould is provided with the injection through hole that diameter is more than shaped notch width in shaped notch bottom so that material can enter shaping well and lack
Mouthful, so that the less reinforcement of thickness can be molded well, avoid the generation of bubble or emptying aperture；Due to going out on split channel
Expect that section is provided with contraction section of the height no more than its feed zone height 2/3 so that molten plastic is hindered in feeding process by contraction section
The effect of power, molten plastic flow velocity is reduced, avoids air from being mixed into molten plastic, influences final product quality；This mould therefore can be with
The continuous extrusion production for the air duct board that this cross sectional shape is complicated, wall thickness is small, and interiors of products bubble-free, finished product are completed well
Quality is good.
, can be according to actual production because distributary division, forming part, discharging portion periphery are designed with the adjustable heating plate of some temperature
Situation is respectively heated to distributary division, forming part, discharging portion so that the flowing forming and plasticizing effect of inner molten plastics
More preferably；Especially the heating of discharging portion can avoid extrusion temperature too low so that air duct board surface quality is poor.
