Abstract
A combined mold for plastic chip solidifying is disclosed. The utility model is characterized in that the combined mold is composed of a bottom plate, 4 to 100 blocking plates with the same thickness and height, and the same or different length, and 4 to 50 nuts; 1 to 5 through hole(s) can be arranged along the height direction of the blocking plate. Rectangular grooves are arranged on the side surface along the height direction; the width of the 1 to 5 groove(s) arranged on the blocking plate equals the thickness of the blocking plate, and the width of the groove arranged at the end part of the blocking plate equals the thickness of the blocking plate or one second thickness of the blocking plate. The utility model is more nimble, the blocking plate is changed to design molds of various shapes and sizes optionally, to solidify PDMS chips of various shapes and sizes required by a laboratory. A plurality of open type cavity bodies of various shapes and sizes can be optionally designed on a bottom plate through a plurality of blocking plates, to solidify the PDMS chips of various shapes and sizes. The embedded type design between the blocking plates has the leakage prevention function, and the design is simple and practical.
Description
Technical field:
The utility model relates to the manufacturing technology of micro-fluidic chip, and a kind of curing mold of making the plastic chip base material that is exclusively used in is provided especially.
Background technology:
Micro-total analysis system (Micro Total Analysis System, μ-TAS) is a frontier interdisciplinary, its final purpose is by the microminiaturization of chemical analysis apparatus and integrated, to greatest extent the function of assay laboratory is transferred to (as all kinds of chips) in the portable analytical equipment, realize " microminiaturization " of assay laboratory, therefore, micro-total analysis system also generically is called " chip lab " (Lab-On-A-Chip), can be divided into two big classes again according to chip structure and working mechanism: micro-array chip (Microarray Chip), be called " biochip " again, and micro-fluidic chip (Microfluidic Chip), the former development is quite ripe, degree of depth industrialization abroad; The latter is mainly based on analytical chemistry and biochemistry, utilize the technology (MEMS) of micro electronmechanical processing, process the microchannel network of 10-100 micron at silicon, glass, quartz, frosting, be driving force mainly with EOF and electrophoresis stream, by changing driving voltage, flow direction and the speed of control fluid in the network of microchannel, thereby realize to target analytes sampling, dilute, add steps such as reagent, enrichment, extraction, mixing, reaction, separation, detection, be the emphasis of current research.Chip manufacturing is one of them pith, and chip material and forming technique have a variety of, and wherein PDMS curing is a kind of method of simple and fast, and manufacturing and designing of PDMS curing mold do not see that bibliographical information is arranged.Common way is in the laboratory at present, constitute the mould of opened type with the framework of a negative and an open type, it has a lot of defectives, as once solidifying a chip substrates, and for a mould, the size shape of chip is immutable, thereby can not satisfy the needs of laboratory work.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can change size neatly, and a plurality of chips of concurrently curable, plastic chip solidifies uses assembling die.
The utility model provides a kind of plastic chip to solidify and used assembling die, it is characterized in that: this assembling die is constituted by negative (1), 4～100 same thickness and height, the baffle plate (2) of identical or different length, 4～50 nuts (3); The short transverse of baffle plate (2) has 1～5 through hole (21).
In order to prevent to leak, the utility model plastic chip solidifies with in the assembling die, and the side of baffle plate (2) has rectangle groove (21) along short transverse; Open the thickness that 1～5 groove (21) width on baffle plate (2) body equals baffle plate, groove (21) width of opening in baffle plate (2) end equals 1/2nd of baffle plate thickness or baffle plate thickness.
Compare with conventional PDMS curing mold, the advantage that the utlity model has is:
1 is more flexible, as long as change baffle plate, just can optionally design the mould of difformity and size, thereby solidify the PDMS chip of the different shape size that the laboratory needs.
2 can optionally design the opened type cavity of a plurality of different sizes and shape with a plurality of baffle plates on same negative, thereby concurrently curable goes out the PDMS chip of a plurality of difformity sizes.
Embedded design between 3 baffle plates has leakage-preventing function, the simplicity of design practicality.
Description of drawings:
Fig. 1 illustrates for plastic chip solidifies with a kind of assembled state of assembling die.
The specific embodiment:
As shown in Figure 1, a negative (1) is arranged in this assembling die, the baffle plate (2) of nine fast same thickness and height, identical or different length, 3 through holes are arranged on the long baffle plate, 2 through holes are arranged on the short shutter, a side of each baffle plate has 2～3 rectangular through slot that do not wait (21), has surrounded the cavity of four opened types between nine fast baffle plates and negative, can be used for solidifying simultaneously the PDMS chip of four different sizes.
Claims (2)
1, a kind of plastic chip solidifies and uses assembling die, it is characterized in that: this assembling die is constituted by negative (1), 4～100 same thickness and height, the baffle plate (2) of identical or different length, 4～50 nuts (3); The short transverse of baffle plate (2) has 1～5 through hole.
2, use assembling die according to the described plastic chip curing of claim 1, it is characterized in that: the side of described baffle plate (2) has rectangle groove (21) along short transverse; Open the thickness that 1～5 groove (21) width on baffle plate (2) body equals baffle plate, groove (21) width of opening in baffle plate (2) end equals 1/2nd of baffle plate thickness or baffle plate thickness.
