Abstract

The utility model discloses vacuum auxiliary injection moulding equipment, which comprises a vacuum extractor and at least two sets of moulding dies. The vacuum extractor is provided with at least two air extracting connectors, each moulding die is provided with a male die and a female die, after the male die and the female die are closed, a closed cavity between the male die and the female die is a cavity, the male die is provided with an air exhaust connector, one end of the exhaust connector is communicated with the cavity inside each moulding die while the other end is communicated with an optional air extracting connector of the vacuum extractor, the moulding dies are provided with sensors for sensing closing of the male dies and the female dies, and the sensors transmit closing signals to the vacuum extractor. The vacuum auxiliary injection moulding equipment can effectively increase quality of products and production efficiency, and is low in cost, simple in structure and easy to be implemented.

Description

The vacuum aided injection molding apparatus
Technical field
The utility model relates to a kind of injection molding apparatus, specifically relates to a kind of injection molding apparatus that helps improving the injection molding product quality.
Background technology
Injection mo(u)lding is molten charge to be expelled to carry out moulding in the mould with specific die cavity, opens mould after the cooling, obtains the product of required form.Mould generally has male model and master mold two parts, between the two confined space is a die cavity behind the mutual matched moulds of male model and master mold, there is air in the die cavity, when injection molten charge in die cavity, if the air in the die cavity is not discharged, can cause die cavity lack of fill, the compressed air deficiencies such as product surface of burning, therefore in the mould design, will fully take into account the exhausting problem of die cavity inside.The method that exhaust is at present generally adopted is the air drain etc. that begins to rehearse on mould, what rely on air flows exhaust naturally, but effect is not very desirable, in forming process, owing to the excessive issuing velocity that influences molten charge of air drag in the mould, make the interior filling of mould product insufficient, that make can produce bubble etc., thereby influenced the quality and the production efficiency of product.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of vacuum aided injection molding apparatus, and this vacuum aided injection molding apparatus can effectively improve product quality and production efficiency, and cost is low, simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of vacuum aided injection molding apparatus, comprise vacuum extractor and at least two sleeve forming moulds, described vacuum extractor has at least two interfaces of bleeding, each described mould all has male model and master mold, between the two enclosed cavity is a die cavity behind described male model and the master mold matched moulds, offer exhaust port on the described male model, described exhaust port one end communicates with the die cavity of mould inside and the other end is connected with arbitrary interface of bleeding of described vacuum extractor, described mould is provided with and is used for the induction public affairs, the sensor of master mold matched moulds, described sensor passes to described vacuum extractor with the matched moulds signal.
The further technical scheme that the utility model adopted is:
Described vacuum extractor has the control section that is used to produce the vacuum generator part that vacuumizes effect and is used to control described vacuum extractor operation, and described sensor passes to the matched moulds signal control section of described vacuum extractor.
Described sensor is made of inductor and sensor block, and inductor is fixed in male model and sensor block is fixed in master mold, or inductor is fixed in master mold and sensor block is fixed in male model.
All be provided with control valve on the described interface of bleeding of on the described vacuum extractor each, described control valve is controlled bleed air-flow break-make in the interface of its place.
On the described vacuum extractor each interface of bleeding all is connected with the exhaust port of arbitrary mould.
The beneficial effects of the utility model are: the utility model is provided with the vacuum extractor with at least two interfaces of bleeding, each of this vacuum extractor interface of bleeding all is connected with the die cavity of a sleeve forming mould inside, by sensor the matched moulds signal is issued vacuum extractor, vacuum extractor is received behind the signal control valve and can be automatically performed to open the air in the mould die cavity is extracted out, injection molding product again when being extracted into the certain limit vacuum state, the control valve of vacuum extractor is closed automatically after finishing, enter next circulation, air drag when the utility model not only can effectively reduce the mould inner stuffing, avoid filling insufficient, the product that makes can produce defectives such as bubble, thereby improved product quality, and the utility model has been realized continuous operation, and can realize of the vacuumize auxiliary operation of a vacuum extractor to many sleeve formings mould, can be applicable to various Shooting Techniques, improved production efficiency, saved cost.
Description of drawings
Fig. 1 is a mould schematic diagram described in the utility model;
Fig. 2 is a vacuum extractor schematic diagram described in the utility model;
The specific embodiment
Embodiment: a kind of vacuum aided injection molding apparatus is described mould as shown in fig. 1, this mould has master mold 1, is located at the sensor block 11 of master mold, male model 2, be located at male model inductor 21, be located at the exhaust port 22 of male model; Be described vacuum extractor 3 as shown in Figure 2, this vacuum extractor has control section 32 and five interfaces 33 of bleeding that are used to produce the vacuum generator part 31 that vacuumizes effect, are used to control described vacuum extractor operation, all is provided with control valve on each interface 33 of bleeding.Exhaust port 22 1 ends communicate with the die cavity of mould inside and the other end is connected with arbitrary interface 33 of bleeding of described vacuum extractor, respond to the matched moulds of male model 2 and master mold 1 by sensor block 11 and inductor 21, inductor 21 passes to the matched moulds signal control section 32 of described vacuum extractor 3,3 actions of control section 32 control vacuum extractors, concluding time is controlled by the control section 32 of vacuum extractor 3, concrete action is: by master mold 1 and male model 2 matched moulds, behind the matched moulds sensor block 11 with can send out the control section 32 that a signal is given vacuum extractor 3 after inductor 21 contacts, the control section 32 of vacuum extractor 3 is received behind the signal control valve and can be automatically performed to open the air in the mould die cavity is extracted out, injection molding product again when being extracted into the certain limit vacuum state, the control valve of vacuum extractor 3 is closed automatically after finishing, enter next circulation, thereby realization continuous operation, and can realize of the vacuumize auxiliary operation of a vacuum extractor to many sleeve formings mould, can be applicable to various Shooting Techniques.
