Description
Technical field
The utility model relates to a kind of sample mould, particularly relates to a kind of batten mould for modified plastics test.
Background technology
When injection molded thermoplastic's goods, usually in some cases, due to the structural factor of the mould relevant to Products Design, the phenomenon that moulded products produces weld mark is almost difficult to avoid completely.Producing the reason of weld mark is due to the melt flows leading peak from different directions in mold filling process, caused by failing to merge completely at meet.The existence of weld mark (weld bond or face of weld) not only affects the presentation quality of goods, what is more important, weld mark can become stress concentration point thus affect the mechanical strength of goods, when goods need secondary processing (as application, plating), the impact of chemical-resistant aspect also can manifest to some extent.In order to avoid the many product quality problems produced because of weld mark, after Product processing is shaping, the test of weld mark aspect must be carried out to preproduction, check whether goods have weld mark, the size of the product quality problem that differentiation causes because of weld mark in various degree, and according to circumstances find the method for dealing with problems.
The intensity in molding product weld marks region, chemical-resistant and apparent property affect by several factors such as Material selec-tion, Products Design, Design of Dies and goods processing conditionss.
The heat seal strength retention (namely having the ratio of the sample of weld bond and its pulling strengrth of sample of weldless line) of comparative material tensile sample is for the welding performance predicting modified plastics, and optimal design is material modified has certain value.Wherein there is the pulling strengrth sample of weld bond, can make with the sample mould that cast gate is offered at two ends simply, and the pulling strengrth sample of weldless line can adopt single cast gate sample mould of normally used standard to make.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, provides a kind of batten mould for modified plastics test.
The utility model is achieved through the following technical solutions:
For the batten mould of modified plastics test, comprise quiet template, moving platen and cavity plate, feature is: described cavity plate be provided with the first die cavity for molding standard tensile sample, the second die cavity for molding standard impact specimen, for the 3rd die cavity of molding standard bend specimen and the cast gate be connected with each die cavity and the runner be connected with cast gate, second die cavity and the 3rd die cavity are vertically arranged in parallel side-by-side, and the upper end of two die cavities arranges cast gate; First die cavity is arranged in the horizontal direction, and be arranged on the top of the second die cavity and the 3rd die cavity, the middle part of the first die cavity arranges cast gate; The runner section of the cast gate of the first die cavity and the cast gate of the second die cavity, the 3rd die cavity all in fan-shaped, and is all connected with runner.
Further, the above-mentioned batten mould for modified plastics test, wherein, described second die cavity is identical with the physical dimension of the 3rd die cavity, and the second die cavity is provided with the projection for the formation of impacting breach, and protruding cross section is triangular in shape.
The substantive distinguishing features that technical solutions of the utility model are outstanding and significant progress are mainly reflected in:
Realize on same cavity plate mould after tensile sample mould, impact specimen mould and bend specimen mould integrated optimization are designed, under equal process conditions, the test batten of one-shot forming three kinds of test-types, corresponding test is carried out, for material modification and optimal design provide foundation to various sample.In addition, adopt cross section to be that fan-shaped cast gate can make molten plastic be full of batten die cavity smoothly, fast, guarantee that flow velocity is even, effectively improve weld mark, reduce batten test error, provide convenience to sampling, material properties test.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: the structural representation of cavity plate.
Embodiment
