The present embodiment provides a kind of mould for the preparation of resin combination measuring mechanical property batten, and this mould is applicable to the resin combination of various viscosity, is particularly useful for the test bars preparation of high viscosity resins composition.
As shown in Figure 2, the mould of the present embodiment comprises cope match-plate pattern 10, lower bolster 20 and seal 30.Wherein, as shown in Figure 3, Figure 4, upper side template 10 is rectangle template, comprises four sides, is respectively first side 111, second side 112, the 3rd side 113 and four side 114.On this, the middle part of the inner surface 115 (namely in Fig. 3 along the direction that vertical paper looks out) of side template is provided with batten die cavity 11, the first sealed groove 12, second sealed groove 13 is provided with from inside to outside successively between the periphery of described batten die cavity 11 and three sides of cope match-plate pattern 10, these two sealed grooves are generally u-shaped, be arranged on the inner side of second side 112, the 3rd side 112 and four side 114, and these two sealed grooves extend certain distance from the lower end of the lower end of second side 112, four side 114 towards the direction of first side 111 respectively.The silastic sealing strip matched is respectively arranged with, sealed groove and silastic sealing strip combination, for by cope match-plate pattern and three side seals corresponding to lower bolster in the first sealed groove 12 and the second sealed groove 13.In addition, as shown in Figure 4, to be provided with at first side 111 place of cope match-plate pattern bottom cope match-plate pattern inner surface 115 downwards, be tilted to the right the first inclined-plane 117 extended to form, the length direction on this first inclined-plane 117 extends along the length direction (left and right directions namely in Fig. 3) of cope match-plate pattern first side 111.Also be provided with the sprue 14 protruding from this outer surface 116 and extend towards the outside on the top of cope match-plate pattern outer surface 116, this sprue is communicated in batten die cavity 11, for being circulated in batten die cavity 11 by resin combination.
As shown in Figure 5, Figure 6, lower bolster 20 is rectangle template, all identical with cope match-plate pattern shape, size.First side 211 place of this lower bolster 20 to be provided with bottom lower bolster inner surface 212 downwards, be tilted to the left the second inclined-plane 214 extended to form, and the length direction on this second inclined-plane 214 extends along the length direction of lower bolster first side 211.Shown in Fig. 7, cope match-plate pattern inner surface 115 and lower bolster inner surface 212 fasten mutually, and form in cope match-plate pattern first side 111 and lower bolster first side 211 place the strip opening 40 that is communicated in batten die cavity 11 after fastening, this opening 40 is namely by the first inclined-plane 117 with the second inclined-plane 214 is formed, for seal 30 being embedded opening wherein, meanwhile, the both ends of two sealed grooves extend to the edge of this opening respectively.
Be understandable that, in the utility model, batten die cavity both can only as described in the embodiment be arranged in cope match-plate pattern, also can be arranged in lower bolster, can also in cope match-plate pattern and lower bolster each setting unit batten die cavity, after cope match-plate pattern and lower bolster fasten, form complete batten die cavity, therefore, the position of batten die cavity is not limited in cope match-plate pattern.Similarly, the Main Function of sealed groove in the utility model is that Combined with Radiotherapy puts sealing strip, and to strengthen the sealing effectiveness of mould, therefore its position is also not limited in and is arranged in cope match-plate pattern, is also not limited only to arrange two sealed grooves.Such as, only sealed groove can be set in lower bolster, or in cope match-plate pattern and lower bolster, sealed groove be set respectively.
In addition, in the utility model, the opening formed after cope match-plate pattern and lower bolster fasten mutually is not limited in the shape of the present embodiment.Such as shown in Fig. 8, opening can also be rectangle, and now, the bossing correspondence of seal is arranged to the rectangular preiection of strip.
In the present embodiment, in order to closely fasten cope match-plate pattern and lower bolster, as shown in Figure 3, some first screwed holes 51 are equipped with at the middle part of cope match-plate pattern 10 and edge, being positioned at the first screwed hole in the middle part of cope match-plate pattern 10 along the length direction of cope match-plate pattern is word order, first screwed hole at cope match-plate pattern 10 edge be then in second side 112, the 3rd side 113, between four side 114 and the second sealed groove 13.As shown in Figure 5, the position one_to_one corresponding of some second screwed hole 52, second screwed holes 52 and the first screwed hole 51 is provided with at the middle part of lower bolster 20 and edge.Utilize bolt to be connected with the first screwed hole, the second screwed hole, realize the tight fastening of cope match-plate pattern and lower bolster.
As shown in Figs. 9 to 11, in the present embodiment, seal 30 is an elongated member, and it comprises the substrate portion 31 of strip and protrudes from substrate portion 31 and the bossing 32 extended along the length direction of substrate portion.This bossing 32 is sealed and matched with above-mentioned opening 40, and the periphery of bossing 32 is provided with lute in, strengthens the sealing effectiveness of bossing and opening further.After bossing is embedded into opening, as shown in Figure 2, the upper side edge 34 that extends along its width of the substrate portion of seal and lower side 35 stretch out the outer surface 116 of cope match-plate pattern and the outer surface 213 of lower bolster, respectively so that engineering staff's dismounting seal.In addition, seal 30 is also provided with the exhaust outlet 33 being communicated in batten die cavity 11, this exhaust outlet 33 is connected to vaccum-pumping equipment by exhaust tube, makes mould inside be negative pressure state.
When utilizing the mould of the present embodiment to prepare test bars, first the bleeding point of seal is connected with vaccum-pumping equipment, the air in batten die cavity is extracted out, makes batten die cavity be in negative pressure state.Now, owing to being provided with sealed groove and sealing strip in cope match-plate pattern and being provided with lute at the bossing outer peripheral face of seal, thus ensure that the sealing of whole mould is good.Secondly, connect sprue with connecting line, utilize negative pressure to import in batten die cavity by the resin combination after vacuum defoamation, after resin is full of batten die cavity, closes bleeding point and sprue, the standard batten of good quality after solidification, can be obtained.Mould due to the present embodiment utilizes negative pressure to import resin combination, therefore without the need to too much considering the viscosity of resin combination, even if high viscosity resins, also can import in shaping mold cavity quickly and easily, thus solve existing mould and be difficult to import the problem of high viscosity resins.
Be understandable that, in the utility model, batten die cavity can be the combination of one or more in tensile test specimen batten die cavity, bending specimen batten die cavity or impact test piece batten die cavity, specifically can determine according to the required measuring mechanical property that carries out.Such as in the present embodiment, batten die cavity 11 is tensile test specimen batten die cavity, and its finally obtained test bars shape is dumb-bell shape.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For person of an ordinary skill in the technical field, can also make other changes in different forms on the basis of the above description, cannot give all embodiments exhaustive here.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
