Abstract
A material handle-free mechanism of an automobile BMC reflector mould comprises a mould core and a cavity, wherein a mould cavity of an automobile reflector is arranged between the mould core and the cavity; the cavity is externally provided with a cavity frame; the cavity frame is provided with a mould plate; the mould plate is provided with an inlet and a sub runner; the cavity frame and the cavity are provided with a cold rubber sleeve; the cold runner sleeve is provided with a cold runner; the sub runner is communicated with the cold runner; the cold runner is communicated with the mould cavity; and the bottom of the mould cavity is provided with a puller. The mechanism is characterized in that two sides of the cold runner are provided with cooling water passages. In the scheme, the cooling water passages arranged at two sides of the cold runner ensure that the BMC material squeezed back to the cold runner is in a softened state and does not thermally solidify to generate a material handle, thus solving the problem of material handle waste of the BMC material. Besides, without marks of a pouring gate, the product made herein is attractive in appearance.
Description
Technical field
The utility model relates to a kind of automobile BMC speculum mould does not have the material handle mechanism, belongs to the mould of plastics field.
Background technology
The reflecting mirror material of producing at present car headlamp is essentially the BMC material, and the BMC material is a thermosets, is recyclable material not.Traditional moulds adopts BMC manufacture of materials automobile speculum, and during injection moulding, the charging from cold runner of BMC material after injection moulding is finished, is stayed BMC material in the cold runner by heat cure, forms product material handle, need cut away.And since BMC be recyclable material not to have caused the waste of the resources of production.And leave the cast gate seal at the material handle place of cutting away, it is attractive in appearance to influence product shape.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of periphery in cold runner to open the but water channel that freezes, guarantee that the BMC material is in soft state, product does not have heat cure material handle, save the resources of production, and product shape automobile BMC speculum mould attractive in appearance there is not the material handle mechanism.
The technical scheme that the utility model automobile BMC speculum mould does not have the material handle mechanism is: comprise mold cores and die cavity, the die cavity that the automobile speculum is arranged between core and the die cavity, die cavity has the die cavity frame outward, on the die cavity frame template is installed, be shaped on charging aperture and runner in the template, the cold runner cover is installed in die cavity frame and die cavity, be shaped on cold runner in the cold runner cover, runner is communicated with cold runner, cold runner is communicated with die cavity, sprue puller is arranged at the bottom of die cavity, it is characterized in that described cold runner both sides are shaped on cooling water channel.
Automobile BMC speculum mould of the present utility model does not have the material handle mechanism, during injection moulding, the BMC material flows into the cold runner through runner from charging aperture, the cold runner design is at the center, lamp socket hole of speculum die cavity, after the BMC material is full of whole die cavity from the cold runner injection moulding, this moment, the place, lamp socket hole of speculum die cavity did not bump dead, also there is one deck clout to exist, the ejecting mechanism of mould drives sprue puller and moves upward (belonging to existing known technology), this layer clout given squeeze back cold runner, and, guaranteed that the BMC material that squeezes back is in soft state owing to being shaped on cooling water channel in the cold runner both sides, can not produce the material handle by the thermosetting flower, solve the material handle waste problem of BMC material.And the product of producing does not like this have the vestige of cast gate, and product appearance is attractive in appearance.
Description of drawings
Fig. 1 is that the utility model automobile BMC speculum mould does not have material handle mechanism structural representation.
The specific embodiment
The utility model relates to a kind of automobile BMC speculum mould does not have the material handle mechanism, as shown in Figure 1, comprise mold cores 1 and die cavity 2, the die cavity 4 that the automobile speculum is arranged between core 1 and the die cavity 2, die cavity has die cavity frame 3 outward, template 5 is installed on the die cavity frame, be shaped on charging aperture 6 and runner 7 in the template, cold runner cover 8 is installed in die cavity frame 3 and die cavity 2, be shaped on cold runner 9 in the cold runner cover, runner 7 is communicated with cold runner 9, and cold runner 9 is communicated with die cavity 4, sprue puller 10 is arranged at the bottom of die cavity 4, it is characterized in that described cold runner 9 both sides are shaped on cooling water channel 11.During injection moulding, the BMC material flows into the cold runner 9 through runner 7 from charging aperture 6, cold runner 9 designs are at the center, lamp socket hole of speculum die cavity 4, after the BMC material is full of whole die cavity 4 from cold runner 9 injection mouldings, place, the lamp socket hole of speculum die cavity 4 does not bump dead at this moment, also there is one deck clout to exist, the ejecting mechanism of mould drives sprue puller 11 and moves upward (belonging to existing known technology), this layer clout given squeeze back cold runner 9, and owing to be shaped on cooling water channel in the cold runner both sides, guaranteed that the BMC material that squeezes back is in soft state, can not produce the material handle by the thermosetting flower, solved the material handle waste problem of BMC material.And the product of producing does not like this have the vestige of cast gate, and product appearance is attractive in appearance.
