Abstract
The exhaust that the utility model discloses a kind of mould enters son, comprise: exhaust pedestal, it is interval with several flutings and several pedestals exhaust sheet, described exhaust pedestal offers through steam vent along the direction being vented sheet place plane orthogonal with described pedestal, and described steam vent is communicated with the bottom of described fluting; Several independent exhaustion sheets, each independent exhaustion sheet is located in an above-mentioned fluting respectively.Because the number of independent exhaustion sheet tails off, half before being about, described pedestal exhaust sheet is by the processing of described exhaust pedestal one, also be independently between each described pedestal exhaust sheet, cumulative limit can not be produced, described independent exhaustion sheet is located in described fluting respectively, also can not produce cumulative limit each other.Therefore, can not produce cumulative limit between each exhaust sheet, the molding structure be located on exhaust sheet also can not produce cumulative limit, and the body of the product appropriate section produced can not misplace, and avoids mould to reprocess, raises the efficiency.
Description
[technical field]
The utility model relates to mould, and the exhaust particularly relating to a kind of mould enters son.
[background technology]
When injection mo(u)lding plastic parts product, die cavity is made to produce gas along with the injection of melt plastic cement liquid, this gas mainly comprises: air existing in die cavity and running gate system, the moisture contained in plastic raw materials at high temperature evaporates produced steam, and in the gas that under high temperature, plastics produces and plastics, some additive volatilizees the gas produced.When injection moulding, if these gases can not be discharged in time from die cavity, then when shaped article these gases can produce pore, gas line, cavity on the surface of product, burn, the great number of issues such as bubble.
Refer to Fig. 1, the exhaust that Fig. 1 illustrates as a kind of mould of prior art enters sub structural representation.This is vented draws together several exhaust sheets 100 be together in series by alignment pin 200 into attached bag.It is many that this type of exhaust sheet 100 processes sheet number, all mismachining tolerance can be produced because of during every a slice processing, be together in series and cause tolerance stack (tolerance × processing sheet number of tolerance stack=every sheet), be vented the molding structure on son, the boss 300 on such as each exhaust sheet 100 top as shown in Figure 1, easily dislocation is more, mutually should mesh dislocation that respectively this boss 300 produces also can be more, mould need repeatedly be reprocessed, and wastes time and energy.
In view of this, be necessary that the exhaust of developing a kind of mould enters son, to solve the problem in fact.
[summary of the invention]
Therefore, the exhaust that the purpose of this utility model is to provide a kind of mould enters son, enter son with the exhaust solving prior art to be connected by several exhaust sheets, cause cumulative limit due to the tolerance of each exhaust sheet, and be located at the shaping body of molding structure on each exhaust sheet and easily misplace more problem.
In order to achieve the above object, the exhaust of the mould that the utility model provides enters son, comprising:
Exhaust pedestal, it is interval with several flutings and several pedestals exhaust sheet, and described exhaust pedestal offers through steam vent along the direction being vented sheet place plane orthogonal with described pedestal, and described steam vent is communicated with the bottom of described fluting;
Several independent exhaustion sheets, each independent exhaustion sheet is located in an above-mentioned fluting respectively.
Optionally, have hanging platform in described fluting, described independent exhaustion sheet has the block corresponding with described hanging platform.
Optionally, described pedestal exhaust sheet and/or described independent exhaustion sheet top have molding structure.
Optionally, described molding structure is boss.
Optionally, described molding structure is groove.
Compared to prior art, the exhaust of the utility model mould is utilized to enter son, because the number of independent exhaustion sheet tails off, half before being about, described pedestal exhaust sheet, by the processing of described exhaust pedestal one, is also independently between each described pedestal exhaust sheet, can not produces cumulative limit, described independent exhaustion sheet is located in described fluting respectively, also can not produce cumulative limit each other.Therefore, can not produce cumulative limit between each exhaust sheet, the molding structure be located on exhaust sheet also can not produce cumulative limit, and the body of the product appropriate section produced can not misplace, and avoids mould to reprocess, raises the efficiency.
[accompanying drawing explanation]
The exhaust that Fig. 1 illustrates as a kind of mould of prior art enters sub structural representation.
Fig. 2 exhaust illustrated as mould of the present utility model enters the structural representation of a sub preferred embodiment.
Fig. 3 exhaust illustrated as mould of the present utility model enters the decomposition texture schematic diagram of a sub preferred embodiment.
[detailed description of the invention]
Incorporated by reference to consulting Fig. 2, Fig. 3, the decomposition texture schematic diagram that Fig. 2 exhaust illustrated as mould of the present utility model enters the structural representation of a sub preferred embodiment, Fig. 3 exhaust illustrated as mould of the present utility model enters a sub preferred embodiment.
In order to achieve the above object, the exhaust of the mould that the utility model provides enters son, comprising:
Exhaust pedestal 10, it is interval with several flutings 11 and several pedestals exhaust sheet 12, described exhaust pedestal 10 offers through steam vent 13 along the direction being vented sheet 12 place plane orthogonal with described pedestal, described steam vent 13 is communicated with the bottom of described fluting 11, is reached the effect of exhaust by described steam vent 13;
Several independent exhaustion sheets 14, each independent exhaustion sheet 14 is located in an above-mentioned fluting 11 respectively.
Wherein, have hanging platform in described fluting 11, described independent exhaustion sheet 14 has the block corresponding with described hanging platform, by cooperatively interacting between described hanging platform and described block, can reach the position-limiting action to described independent exhaustion sheet 14.
Wherein, described pedestal exhaust sheet 12 and/or described independent exhaustion sheet 14 top have molding structure, in order to the appropriate section of shaped article.In the present embodiment, described molding structure is boss 15, in order to the mesh on shaped article; Certainly, described molding structure is groove or other structure, in order to the rib on shaped article and other shape.
The exhaust of the utility model mould is utilized to enter son, the number of independent exhaustion sheet 14 tails off, half before being about, described pedestal exhaust sheet 12 is by the processing of described exhaust pedestal 10 one, also be independently between each described pedestal exhaust sheet 12, can not produce cumulative limit, described independent exhaustion sheet 14 is located at respectively in described fluting 11, also can not produce cumulative limit each other.Therefore, can not produce cumulative limit between each exhaust sheet, the molding structure be located on each exhaust sheet also can not produce cumulative limit, and the body of the product appropriate section produced can not misplace, simultaneously easy to assembly, avoids mould to reprocess, raises the efficiency.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification that any those skilled in the art do above-described embodiment based on technical solutions of the utility model, equivalent variations and modification, all fall in protection domain of the present utility model.
