Oil sealing can directly pass through one-pass molding, specially design a set of molding die, produce to batch.Compare injection molding, benefit
With powder pressing forming, then it to be used for the processing of special oil sealing product, intensity is higher, and the consistency of properties is more preferable, comprehensive
Performance is more preferably.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of device of powder compacting oil sealing, should
Structure designs the performance that can give full play to press machine, is especially the comprehensive performance of molded blank part each more preferable to consistency.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of device of powder compacting oil sealing, packet
It includes press machine and is mounted on the mold for being used for powder pressing forming oil sealing blank on press machine, the mold includes cope plate
And lower template, cope plate are fixedly connected with mounting plate, and punch-pin is provided on mounting plate, and cavity plate, cavity plate center are equipped in lower template
Position is equipped with insert, and the toroidal cavity between insert and cavity plate constitutes the molding space of oil sealing blank, is equipped with heating in insert
Block and sealing ring are machined with cooling pipe in cavity plate.
Further, the draft that 1-3 degree is equipped on the contact surface of punch-pin as described above, cavity plate and insert three is oblique
Degree.
Further, the mandril of insert as described above and mold bottom is fixedly linked and is equipped between insert and cavity plate
Several sealing rings.
Further, pressure sensor is installed in the cavity between punch-pin and cope plate as described above.
Further, cooling water temperature is passed through in cooling pipe as described above.
Further, if being equipped with dry temperature sensor in cavity plate as described above.
Compared with prior art, the utility model has the beneficial effects that the present apparatus by molding space carry out heating and
Cooling, temperature collection information obtains final products, to protect to apply suitable pressure and corresponding pressure maintaining discharge time
Demonstrate,prove the quality of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
The label in accompanying drawing is: 1. pressure sensors；2. cope plate；3. mounting plate；4. punch-pin；5. cavity plate；6. lower die
Plate；7. insert；8. sealing ring；9. heat block.
Specific embodiment
Be described in detail below with reference to embodiment referring to attached drawing, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in Figure 1, a kind of device of powder compacting oil sealing of the utility model, including press machine and it is mounted on press machine
The upper mold for powder pressing forming oil sealing blank, the mold include cope plate 2 and lower template 6, and cope plate 2 is fixed
Connection plate 3, punch-pin 4 is provided on mounting plate 3, and 4 top of punch-pin is equipped with the ring part of outwardly convex, size and oil sealing blank
Part is identical, and cavity plate 5 is equipped in lower template 6, and 5 center of cavity plate is equipped with insert 7, and 7 center top of insert is equipped with outwardly convex,
Size is identical as the inner circle of oil sealing blank, and the molding that the toroidal cavity between insert 7 and cavity plate 5 constitutes oil sealing blank is empty
Between, powder is added in the molding space, it is general to select plastic tree cosmetics, heat block 9 and sealing ring 8, cavity plate 5 are equipped in insert 7
In be machined with cooling pipe.
Further, the pattern draft of 1-3 degree is equipped on the contact surface of 7 three of the punch-pin 4, cavity plate 5 and insert,
Specific pattern draft is related with the material of the raw material powder of oil sealing blank, convenient for being vented and the later period is convenient in demoulding.Institute
The mandril of the insert 7 stated and mold bottom is fixedly linked and is equipped with several sealing rings 8 between insert 7 and cavity plate 5.
Further, pressure sensor 1 is installed in the cavity between the punch-pin 4 and cope plate 2, real-time detection is convex
The size of 4 pressing force of mould is passed through cooling water temperature in the cooling pipe, and heat block 9 is copper rod resistance heating, described
If cavity plate 5 in be equipped with dry temperature sensor, for the temperature during real-time detection powder compacting.
In utility model device, the mould assembling action of press machine, mainly punch-pin 4 are moved downward, by temperature sensing
The influence of device feedback parameter, while the size of the application active force of punch-pin 4 and time are also controlled, specific parameter association can pass through
Multiple die trial obtains, wherein the components such as the sensor and heat block 9 are the prior art or material, affiliated technical staff
According to required product type and specification, can directly be bought from market or tailor-made.
Clear, complete description is carried out to the utility model by the technical solution in above embodiments, it is clear that described
Embodiment be the utility model a part embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
