Abstract
The invention provides a sealing detection fixture. The sealing detection fixture comprises a lower die and an upper die, wherein an annular sealing member which is contacted with a parting surface of a product to be tested is arranged on the upper surface of the lower die; and an exhaust hole is formed in the lower die in a ring of the annular sealing member. The upper die is mounted and connected with an air cylinder; when the upper die presses towards the lower die, a closed cavity from which air can be extracted is formed between the product to be tested and the sealing detection fixture; a sealing ring for sealing a screw hole of the product to be tested is arranged on the upper die; and a mold core insert for sealing a battery compartment of the product to be tested is arranged on the upper die. The sealing detection fixture can be used for integrally checking product parts and assemblies and testing at a time to judge whether the parts meet the requirement or not. The negative pressure generated by exhausting from the inside is matched with the stress on an actual product in deep water, and thus the simulation is more vivid. The internal air pressure is displayed in real time by using a barometer; the quantitative judgment is realized by the change of an air pressure value and is fed back to the computer, and thus automatic judgment is finished.

Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better,, the present invention is done further detailed description below in conjunction with accompanying drawing and embodiment.
Sealing detection tool of the present invention is the equipment of a test semi-manufacture assembly water proofing property.Product to be tested has a plurality of little plastic parts assemblies to form, and a plurality of cooperation stations are arranged.Have the leakage problem after the semi-manufacture assembled that the bad and little glue spare defective of a plurality of cooperation stations assembling itself causes, need detect semi-manufacture.
Like Fig. 1, Fig. 2 and shown in Figure 3, the sealing detection tool can be divided into counterdie and two parts of patrix.The upper surface of counterdie is provided with the lip ring 9 that contacts with product 17 die joints to be tested, and corresponding counterdie zone is provided with and leads to the outer aspirating hole 16 of mould in the ring of lip ring 9.Patrix is installed through bolt and cylinder and is linked together, and cylinder does not draw among the figure.When patrix was pressed to counterdie, product 17 to be tested and sealing detected the cavity that can deflate 18 that forms a sealing between tool.
Counterdie is provided with vertical guide pillar 1, and patrix is provided with can be along the guide pillar hole that guide pillar 1 slides up and down.Counterdie is provided with the spacing cushion block 14 that guarantees distance between counterdie and the patrix.
Several screw O-ring seals 8 of tool patrix seal with corresponding product to be tested 17 screw holes respectively.Patrix is provided with the core rod mold insert 4 that is used to seal product 17 battery compartments to be tested.
With reference to figure 4, counterdie comprises lower bolster 11 and the lower mold core 10 that is installed in lower bolster 11 tops, and lip ring 9 is installed in the upper surface of lower mold core 10.The upper surface of the lower mold core 10 of the ring inner region of lip ring 9 is provided with the guide-localization structure 19 with the respective outer side edges of product 17 to be tested.Aspirating hole 16 passes lower bolster 11 and lower mold core 10, leads in the annular extent of lip ring 9.Be provided with air extracting seal circle 15 between the surface of contact of the lower surface of lower mold core 10 and lower bolster 11.
Patrix comprises the web joint 2 that is used to be installed on the cylinder, and the cope match-plate pattern 5 of O-ring seal 8 and core rod mold insert 4 is installed in the web joint below.Web joint 2 screws through plug and 12 is installed in the top of cope match-plate pattern 5 with guiding regulating spring 13, is provided with back-up block 3 between cope match-plate pattern 5 and the web joint 2.Spatial structure such as Fig. 5, shown in Figure 6.The bottom of cope match-plate pattern 5 is installed with upper mold core 6, and microscler sealing mold insert 7 vertically passes upper mold core 6 from the top of upper mold core 6.Screw hole O-ring seal 8 is installed in the end of microscler sealing mold insert 7, is positioned at the below of upper mold core 6.Core rod mold insert 4 also is installed in the bottom of upper mold core 5.
When the tool patrix was depressed, patrix passed through the corresponding screw hole of screw hole O-ring seal 8 good seal products, the core rod mold insert 4 of the patrix flexible glue TPU pressing peripheral simultaneously with the product battery compartment, and the good seal battery compartment, thus form the seal chamber 18 between tool and product.
Test process and step explanation.
Step 1: product 17 die joints to be tested through the tool location, are put into the tool counterdie down, and die joint is contacted with the lip ring 9 of tool.
Step 2: the closed safe door, press start button, cylinder begins to drive the tool patrix and down moves, and when the tool patrix was depressed: A) patrix screw hole O-ring seal 8 was out of shape the corresponding screw hole that comes the good seal product with the interference of product 17 to be tested; B) the core rod mold insert 4 of the patrix TPU flexible glue interference pressing peripheral with product 17 battery compartments to be tested, the good seal battery compartment; C) product to be tested 17 and ring-like seal 9 interference pressings, thus the seal chamber 18 of 17 of tool and products to be tested formed.
Step 3: after tool and product to be tested 17 formed seal chamber 18 when cylinder was depressed, start air extractor, begin to extract out air in the cavity, make inside cavity form negative pressure.Cavity links to each other with barometer simultaneously, dynamically shows the cavity internal gas pressure.Bled 5 seconds, the cavity air pressure that product and tool are formed reaches preset atmospheric pressure value.
Step 4: after atmospheric pressure value reached predetermined air pressure, the closed gas circuit of valve-off was observed barometrical atmospheric pressure value and whether is met the predetermined dimension scope, and judges whether product is qualified.If atmospheric pressure value is stabilized in official hour in the predetermined atmospheric pressure value scope, product promptly meets the demands.
Embodiments of the invention use the formation negative pressure of bleeding internally to come the final user mode of real simulation product to check.The tool patrix presses down to counterdie in the drive of cylinder, makes the cavity of a sealing of intermode formation on tool counterdie, product and the tool.Be applicable to that there are a plurality of assembling elements in product to be tested, and need through its water resistance of disposable detection.This technical scheme can use differential pressure gauge to come the measures of quantization standard.
Foregoing is merely preferred embodiment of the present invention, is not the present invention is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to main design of the present invention and spirit.So protection scope of the present invention should be as the criterion with the covering scope of claim.
