Abstract
The utility model discloses the die trial of a kind of Double-bottom-plate plastics, comprise the housing of four side plate compositions, and be arranged on two base plates of housing bottom, two base plates are all connected with four side plates, two base plates are upper plate and lower shoe, between upper plate and lower shoe, there is gap, lower shoe offers air admission hole, upper plate comprises gear air parcel and some steam vents, because the steam vent of upper plate is less, the slip of thickness can not spill from hole, directly slip is poured in mould during cast, during the demoulding, air admission hole is held out against jet with the spray gun of air pump, the gas of ejection runs into gear air parcel and scatter and make pressure increase in cavity, finally discharge from each steam vent, sample also ejects thereupon, this device can make uniform force bottom sample, because gas impulsive force causes greatly this problem of specimen fails when solving the plastics die trial air pump demoulding well.
Description
Technical field
The utility model belongs to testing equipment field, is specifically related to the die trial of a kind of Double-bottom-plate plastics.
Background technology
Now widely used plastics die trial is made up of four side plates and a base plate, and centre arranges air admission hole in the soleplate, is extruded by sample during the demoulding with air pump.This mould structure is fairly simple, easy to process.Its shortcoming is, during the demoulding, air-flow directly acts on sample, and gas shock power is large, and the force part of sample is concentrated, and easily causes the damage of sample, time particularly for the sample that foam cement equal strength is lower, very easily causes sample cracking.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides the die trial of a kind of Double-bottom-plate plastics, can avoid the damage during demoulding.
In order to achieve the above object, the utility model comprises the housing of four side plate compositions, and be arranged on two base plates of housing bottom, two base plates are all connected with four side plates, two base plates are upper plate and lower shoe, have gap between upper plate and lower shoe, lower shoe offers air admission hole, upper plate comprises gear air parcel and some steam vents.
Diameter≤the 2mm of described steam vent.
Described air admission hole is opened in the central authorities of lower shoe, and gear air parcel is corresponding with air admission hole.
Steam vent around the gear air parcel of described upper plate is distribution in " rice " font.
Described steam vent is 80, and diameter is 1.5mm.
Steam vent around the gear air parcel of described upper plate is distribution in " X " shape.
Described steam vent is 48, and diameter is 2mm.
Compared with prior art, the utility model due to the steam vent of upper plate less, the slip of thickness can not spill from hole, directly slip is poured in mould during cast, during the demoulding, hold out against air admission hole jet with the spray gun of air pump, the gas of ejection runs into gear air parcel and scatter and make pressure increase in cavity, finally discharge from each steam vent, sample also ejects thereupon; This device can make uniform force bottom sample, because gas impulsive force causes greatly this problem of specimen fails when solving the plastics die trial air pump demoulding well.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is top view of the present utility model;
In figure: 1 is side plate, 2 is lower shoe, and 3 is upper plate, and 2-1 is air admission hole, and 3-1 is steam vent, and 3-2 is gear air parcel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
See Fig. 1 and Fig. 2, the utility model comprises the housing that four side plates 1 form, and be arranged on two base plates of housing bottom, two base plates are all connected with four side plates, two base plates are upper plate 3 and lower shoe 2, have gap, the central authorities of lower shoe 2 offer air admission hole 2-1 between upper plate 3 and lower shoe 2, upper plate 3 comprises the diameter≤2mm of the gear air parcel 3-2 corresponding with air admission hole 2-1 and some steam vent 3-1, steam vent 3-1.
Embodiment 1:
The utility model comprises the housing that four side plates 1 form, and be arranged on two base plates of housing bottom, two base plates are all connected with four side plates, two base plates are upper plate 3 and lower shoe 2, between upper plate 3 and lower shoe 2, there is gap, the central authorities of lower shoe 2 offer air admission hole 2-1, upper plate 3 comprises the gear air parcel 3-2 corresponding with air admission hole 2-1 and some steam vent 3-1, steam vent 3-1 around the gear air parcel 3-2 of upper plate 3 is distribution in " rice " font, steam vent 3-1 is 80, and diameter is 1.5mm.
Embodiment 2:
The utility model comprises the housing that four side plates 1 form, and be arranged on two base plates of housing bottom, two base plates are all connected with four side plates, two base plates are upper plate 3 and lower shoe 2, between upper plate 3 and lower shoe 2, there is gap, the central authorities of lower shoe 2 offer air admission hole 2-1, upper plate 3 comprises the gear air parcel 3-2 corresponding with air admission hole 2-1 and some steam vent 3-1, steam vent 3-1 around the gear air parcel 3-2 of upper plate 3 is distribution in " X " shape, steam vent 3-1 is 48, and diameter is 2mm.
During use, poured into by slip in this device, the slip of thickness can not spill from hole, during the demoulding, hold out against air admission hole jet with the spray gun of air pump, the gas of ejection runs into gear air parcel and scatter and make pressure increase in cavity, finally discharge from each steam vent, sample also ejects thereupon.
