Abstract
The utility model relates to an injection mould of thermoplastic polyurethane elastomer for a test, which is used for achieving the purpose of quickly obtaining a test sample for a plastic piece hardness test, a tensile test and a tear resistance test with low cost. The injection mould comprises a core mould body, and is characterized in that a closed cover matched with the core mould body is arranged, wherein a circular sample strip slot, a dumbbell sample strip slot and a right angle type sample strip slot are arranged in the core mould body; and charging holes are respectively formed in parts opposite to the circular sample strip slot, the dumbbell sample strip slot and the right angle type sample strip slot on the closed cover. The injection mould disclosed by the utility model is simple and reasonable, capable of forming various test sample strips by one step, efficient and energy-saving, low in manufacturing cost, wide in range of application, and very suitable for an injection molding test which is few in sampling times and various in sampling types.
Description
Technical field
The utility model relates to technical field of mold, relates in particular to a kind of injection mold of testing with TPUE.
Background technology
Injection mold generally designs by product according to basic principle, carry out independent improvement for certain concrete defect simultaneously, if patent publication No. is CN103009559A, disclosed a kind of injection mold, comprise die cavity, runner and injection orifice, arranged outside at runner and injection orifice has heater, and to prevent cooling waste material, this design is mainly used in the Shooting Technique of larger product.And for example patent publication No. is CN102490322A, a kind of injection mold proposing, comprise solid plate and moving platen, on moving platen, be provided with core-pulling mechanism, outside at solid plate is provided with locking member, on moving platen, is connected is provided with locking member holder with core-pulling mechanism, and one end of locking member is connected with solid plate, its other end forms and is flexibly connected with locking member holder, and this device is mainly for the product processing with the requirement of loosing core.For another example patent publication No. is CN103057041A, disclosed a kind of injection mold, and dynamic model is provided with the projection of two shaped articles, and two projections are provided with and are positioned at collinear runner; Separately establish a spill spin block matched in clearance and axial limiting in the through hole of dynamic model, dynamic model is also provided with the stopping means of circumferential rotary limited piece, and the top of spill spin block is provided with first flow, the second runner and the 3rd runner that can be communicated with the runner of corresponding projection.This injection mold structure complexity, the same production that is applicable to larger injecting products, the above mould structure is all not suitable for making the making of test specimen mould, and automatic trip sample Die price is high, manufacture craft is also very complicated.
Summary of the invention
The purpose of this utility model is the sample problem that obtains plastic hardness test, tension test, tear-resistant test in order to solve fast and low-cost, provides a kind of reasonable in design, one module multiple usages, simple to operate, size to test accurately the injection mold with TPUE.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of injection mold of testing with TPUE, comprise core block, it is characterized in that coordinating and establishing a closing lid with described core block, in core block, be provided with circular batten groove, dumb-bell shape batten groove, square batten groove, in closing lid, the position of relatively circular batten groove, dumb-bell shape batten groove, square batten groove is respectively equipped with charging aperture.The hardness test of TPUE, tension test, the needed sample of tear-resistant test, all required fixed dimension, and sample inside is without bubble, and a batch products is preferably tested simultaneously.TPUE itself is that solid form exists, and the mode that obtains sample is also generally the method for taking injection mo(u)lding.The technical program is arranged on three kinds of samples in same core block simultaneously, and sample materials can be same batch, also injection moulding separately.This device also helps harvesting.
As preferably, described core block and closing lid are hinged by hinge.Closing lid and core block be as the upper and lower mould in mould, but this device connects by hinging manner, more convenient to operate.
As preferably, the side that described core block and closing lid coordinate is provided with switch latch.Core block and closing lid are one group of molds that precision is relatively high after coordinating, and switch latch guarantees both quality of fits.
As preferably, the back side of the described relative closing lid of core block is provided with screw.This device is fixed with injection machine by screw or is connected.
As preferably, the plane that described core block and closing lid coordinate is light face.For guaranteeing to obtain standard sample.
As preferably, in described core block, be provided with several circular batten grooves, the radius of circular batten groove is 5mm, is highly 3mm.Multiple sample groove is set in same core block, can carries out the injection moulding of many testing bars simultaneously, make full use of the volume of core block, reduce operation sequence, reduce costs.
Effective effect of the present utility model is: simple and reasonable, can disposablely carry out multiple test bars moulding, and energy-efficient, low cost of manufacture, the scope of application is wide, is applicable to very much the injection mo(u)lding test that number of times is few, the kind of drawing a design is many of drawing a design.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of working state structure schematic diagram of the present utility model.
In figure: 1. core block, 2. closing lid, 3. circular batten groove, 4. dumb-bell shape batten groove, 5. hinge, 6. charging aperture, 7. square batten groove, 8. screw, 9. switch latch.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, a kind of injection mold of testing with TPUE of the present embodiment, formed by core block 1 and closing lid 2, core block 1 is connected by hinge 5 with closing lid 2 one sides, another three sides are respectively equipped with switch latch 9, establish two screws that are connected with injection machine 8 in closing lid 2 bottoms, as shown in Figure 2.In core block 1, establish two circular batten grooves 3 for hardness test side by side, the radius of circular batten groove is 5mm, is highly 3mm; The dumb-bell shape batten groove 4 of a tension test test use, dumb-bell shape batten flute length 25mm, wide 6.1mm, high 2mm; A square batten groove 7 arranged side by side with dumb-bell shape batten groove 4, the square batten groove 7 height 2mm of tear-resistant test use.Meanwhile, in closing lid 2, offer respectively charging aperture 6 with respect to the position of circular batten groove 3, dumb-bell shape batten groove 4, square batten groove 7.Core block 1 and closing lid 2 adopt metal material to make, and mating surface is between the two burnishing surface.
When use, use this device by product sample requirement, the circular batten groove 3 of can hardness test using, the dumb-bell shape batten groove 4 of tension test test use, the square batten groove of tear-resistant test use carry out injection moulding acquisition simultaneously, also can need anything to carry out separately injection moulding acquisition.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after simple transformation of the present utility model is all belonged to protection domain of the present utility model.
