Abstract

The utility model discloses a mould pressing device for porcelain insulator blanks. The mould pressing device comprises a prepressing device (1), and is characterized by further comprising a mould pressing apparatus (2), the mould pressing apparatus (2) comprises an upper mould (3) and a lower mould (4), a rotary motor (5) is connected to the lower part of the lower mould (4), and a lifting air cylinder (6) is connected to the upper part of the upper mould (3). By adopting the technology provided by the utility model, the pug consumption is reduced by 30 percent, the efficiency is improved by 20 percent, and the defective rate of products is lower than 5 percent. Compared with the prior art, the mould pressing device provided by the utility model has the advantages of lowered manual operation strength, high product accuracy, stable quality, wide application range, improved production efficiency, reduced pug consumption and lowered product cost.

Description

Porcelain insulator blank molding device

Technical field

The utility model relates to a kind of porcelain insulator blank molding device, belongs to the porcelain insulator processing technique field.

Background technology

The blank of dish type porcelain insulator processing at present, after normally pug being extruded, slightly be pressed into bulk, on blank rotating machine, manually process the inner surface of porcelain insulator then with cutter, manually be transported to trimming machine then from blank rotating machine, and upset porcelain insulator blank, artificial again outer surface with cutter processing porcelain insulator.Shortcoming is that most of operation is manual operation, and equipment falls behind, and labour intensity is big, and product quality judges by operator's experience that mainly quality is stable inadequately, and rate of finished products is low, and operating efficiency is also very low.Simultaneously, in the existing technology, most of pug work in-process of blank is drawn away by cutter, and waste is serious.

Summary of the invention

The purpose of this utility model is: provide a kind of porcelain insulator blank molding device, automaticity height, the quality and the dimensional accuracy height of raising product.

The utility model is to constitute like this: porcelain insulator blank molding device, comprise prepressing device, and comprise that also molding device, molding device comprise mold and bed die, below bed die, connect electric rotating machine, above mold, connect lift cylinder.

Above-mentioned porcelain insulator blank molding device, described mold is provided with the release agent nozzle.

Above-mentioned porcelain insulator blank molding device, described mold is provided with air nozzle.

Above-mentioned porcelain insulator blank molding device, described bottom mold surface is provided with gypsic horizon.

The utility model discloses operation, blank through after the mold pressing, can be obtained porcelain insulator shape roughly, make things convenient for following process, reduce the use of porcelain insulator blank pug the compression molding of porcelain insulator blank.While can also push moulding to blank, improves the intensity and the electric property of blank inside.In R﹠D process, the applicant finds, because complex-shaped (as shown in Figure 2) of porcelain insulator blank, its edge is too high, blank marginal portion pug is very few, inner bonding force is not enough, if just adopt common mould pressing technology, after its mould and blank pressurized are bonding, mold clings the pug at edge easily during the demoulding, destroys the shape of blank, so fast rotational is adopted in mold pressing, the mode that low speed presses down, make blank in mold process, carry out relative motion with mold all the time, the phenomenon of foundry loam can when the demoulding, not occur, improved ratio defective product, and the porcelain insulator blank also will carry out the processing of follow-up cutter and just can obtain final product, can not influence the precision of blank.Through applicant's test, technology of the present utility model can reduce by 30% pug consumption, improves 20% efficient, and the defect rate of product is lower than 5%.Compare with prior art, the utlity model has following advantage: 1) reduce manual operation intensity; 2) product precision height, steady quality; 3) appropriate products quantity is wide; 4) enhance productivity: 5) reduce the pug use amount, reduce product cost.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of dish type porcelain insulator.

Embodiment

Embodiment of the present utility model: porcelain insulator blank molding device, as shown in Figure 1, comprise the prepressing device 1 that blank is carried out precompressed, on prepressing device 2 next doors molding device 2 is set, the structure of molding device 2 comprises mold 3 and bed die 4, below bed die 4, connect electric rotating machine 5, above mold 3, connect lift cylinder 6.Release agent nozzle 7 is installed in mold 3, and release agent nozzle 7 connects the release agent spraying equipment, prevents that blank and mold 3 are bonding.

Air nozzle 8 is installed in mold 3, and air nozzle 8 connects air compressor machine, after the blank mold pressing, can remove the residual pug in the mold.

At bed die 4 surface-coated gypsic horizons 9, in mold process, enough frictional force can be arranged, drive blank and rotate, also be convenient to during the demoulding separate, be difficult for clinging pug.

Prepressing device 1 also is divided into up and down mould, and the pug that cuts off is pressed into roughly pie, and the shape of its bed die is similar to bed die 4 shapes of molding device 2, makes things convenient for blank fixing and following process in molding device 2 bed dies 4.

The course of work is as follows: columniform pug is pressed into pie in advance with the mould of prepressing device 1, obtain the porcelain insulator blank of design shape by molding device 2 mold pressings, in mold process, bed die 4 is driven by electric rotating machine 5, make blank continue rotation, keep relative motion with mold 3, blank is come off by the mould adhesion when preventing the demoulding, destroys the profile of blank.

Through test, the speed of blank rotation is 200-400 rev/min, can satisfy the requirement of rotation mold pressing, can the rotation because of blank not cause the blank compressive deformation in mold process, and reach desirable shape requirement.Especially, the speed of blank rotation is 250-350 rev/min, and effect is best.

More convenient for the demoulding, blank by the release agent nozzle 7 in the mold 3, continues the spraying release agent at the blank upper surface when mold pressing.Release agent is purchased existing finished product.
