[technical field]
The present invention relates to the exhaust gear in a kind of mould, be specifically related to a kind of automatic locking exhaust gear.
[background technology]
In the time of injection molding product, make die cavity produce gas along with the injection of melt plastic cement, this gas mainly comprises existing air in die cavity and running gate system; The moisture containing in plastic raw materials at high temperature evaporates produced steam; Some additive gas producing that volatilizees in the gas that under high temperature, plastics produces and plastics.In the time of injection moulding, if these gases can not be discharged in time from die cavity, in the time of formed product these gases can produce pore, cavity on the surface of product, burn, the great number of issues such as bubble, now needs to use exhaust and enter son or expulsion element, and the exhaust mode conventionally adopting in mould there are following two kinds of modes:
Mode one: refer to Fig. 1 and illustrate, exhaust is entered to son 10 and do logically in die 20, utilize described exhaust to enter son 10 hanging platform 11 and be connected to be fixed up with described die 20, thereby carry out exhaust;
Mode two: refer to Fig. 2 and illustrate, exhaust is entered to son 20 do half-pass in die 30, utilize screw 50 that described exhaust is entered to son 20 and be fixed up with described die 40, then utilize the steam vent 31 that described die 40 is offered to carry out exhaust.
But adopt above-mentioned two kinds of modes can make cannot be below exhaust enters son draining road, and the water route of arranging all needs to avoid exhaust and enters son, thereby affected the quality of product after moulding; Owing to wanting good shaped article, just need to design different exhausts and enter the row method of minor structure with corresponding water route again, seek unity of standard and increased the complexity of mould simultaneously thereby cannot make exhaust enter son.
In view of this, be in fact necessary to provide a kind of exhaust gear, solving mould structure complexity, cannot enter to carry out under son draining road and cannot unify exhaust to enter in exhaust the problem of substandard.
[summary of the invention]
Therefore, automatic locking exhaust gear provided by the invention, can solve and above-mentionedly cannot enter to carry out under son the problem on draining road and the problem of mould structure complexity in exhaust.
In order to achieve the above object, automatic locking exhaust gear of the present invention, it is applied in mould, and this mould comprises male die core and mother module core, and this male die core is provided with some lock buckling grooves, and wherein, this automatic locking exhaust gear comprises:

At least one securing member, it is arranged in described some exhausts and enters in son and described some exhausts are entered to sub fastening serial connection to be integrated;
Flexible member, it is located at described exhaust and enters in son;
At least one the first guide pillar, it is arranged in described some exhausts and enters in son, and one end of this first guide pillar connects a side of described flexible member, and the other end of this first guide pillar stretches out described some exhausts and enters a side of son and coordinate with described lock buckling groove;
At least one the second guide pillar, it is arranged in described some exhausts and enters in son, and one end of this second guide pillar connects the opposite side of described flexible member, and the other end of this second guide pillar stretches out described some exhausts and enters sub another side and coordinate with described lock buckling groove.
Preferably, described the first guide pillar and the second guide pillar have respectively two, and described flexible member is two spring leafs.
Preferably, described two spring leafs be located at respectively described some exhausts enter son in the middle of two adjacent exhausts enter in son.
Preferably, the described two spring leafs wherein two ends of connect respectively described two first guide pillars, and the two ends of another piece connect respectively described two second guide pillars.
Preferably, described securing member, the first guide pillar and the second guide pillar are parallel to each other.
Preferably, described securing member, the first guide pillar and the second guide pillar all enter sub vertical with described exhaust.
Preferably, described exhaust enters the cuboid that is shaped as of son, and the length on two limits that described cuboid is vertical with described securing member, the first guide pillar and the second guide pillar is greater than respectively 30mm.
Preferably, described securing member is fixed screw.
Automatic locking exhaust gear of the present invention, connect to be integrated and to enter sub centre in these some exhausts and put into two spring leafs by utilizing fixed screw that several exhausts are entered to substring, then two spring leafs are connected with first and second guide pillar, enter son thereby realized automatically fixing exhaust.
Compared to prior art, this mechanism also has the following advantages: this mechanism is suitable for various use exhausts and enters the more mould of son; Needn't run through die and simultaneously also do not need screw that itself and die are fixed because this mechanism's exhaust enters sub design, therefore can optimize row's method in water route, get rid of conventional exhaust and enter the drawback of subband; Simplify mould complexity, made mould structure simple, with low cost.
