Abstract

The utility model discloses a special blow molding mould of a plastic bulk vessel, which comprises a mould frame, wherein, a cutting mouth is arranged at a vessel drainage opening blown from the mould frame; simultaneously, a drainage opening tappet mouth apparatus is fixed on a mould frame position exactly opposite to the cutting mouth; the drainage opening tappet mouth apparatus can be moved and propped into the cutting mouth for molding the plastic mouth at the vessel drainage opening. The drainage opening tappet mouth apparatus comprises a mounting base, a tappet, the cutting mouth and a drive apparatus; the tappet is connected with the drive apparatus via a tappet bar and arranged on the mounting base (2); the whole apparatus is fixed on the mould frame via the mounting base. The utility model has the advantages of one-step molding of the product, requiring no secondary processing, ensuring integrity of the product, solving the uneven wall thickness at the drainage opening, ensuring verticality between the end face of the drainage opening and the axis, ensuring the cleanliness of the product and more reliability of the valve installation, shortening the production period of the product, and improving product efficiency.

Description

Special-purpose blow mold of plastics bulk container and leakage fluid dram thimble notching mechanism

Affiliated technical field:

The utility model belongs to the plastics forming field of mechanical technique, particularly the architecture advances of hollow blow molding mould.

Background technology

The plastics bulk container as shown in Figure 1, its downside has leakage fluid dram, this leakage fluid dram mould molding generally has dual mode, one is to make blind screwhole herein on the mould as shown in Figure 2, the goods after the moulding as shown in Figure 3.It is to make blind hole herein on the mould two as shown in Figure 4, and the moulding screw thread mouth that must will produce in advance before blowing is manually put into mould, carries out blowing again, makes plastics and moulding screw thread mouth stick into one, and the goods after the moulding as shown in Figure 5.

This dual mode must carry out otch for the second time and be processed into as shown in Figure 6 shape.The technology of first kind of mode causes that easily screw thread mouth wall unevenness and secondary operations cause problems such as cut surface and leakage fluid dram axle center out of plumb, make the seepage phenomenon after valve is installed unreliable and installation easily, when peril of transportation liquid hidden danger might take place, do not reach relevant national standard requirement.Problems such as the technology of the second way causes to bore easily cuts the bad grasp of endoporus concentricity, and how not the plastics dust easy to clean, and injection moulding screw socket adhesive strength is not enough.

Summary of the invention

The utility model purpose provides special-purpose blow mold of a kind of plastics bulk container and leakage fluid dram thimble notching mechanism, to overcome the deficiencies in the prior art part.

Specifically, the special-purpose blow mold of a kind of plastics bulk container, has the mould body, it is to blow to container leakage fluid dram position the otch edge of a knife (4) is installed on the mould body, simultaneously is fixed with on the position and can moving and head into the leakage fluid dram thimble notching mechanism of the otch edge of a knife to the plastics otch moulding of container leakage fluid dram place being positioned at recessing tool mouth (4) on the mould body.

Plastics bulk container leakage fluid dram thimble notching mechanism in the above-mentioned mould, it comprises mounting base (2), thimble (3), the otch edge of a knife (4) and promotes the actuating unit (1) that thimble moves, thimble (3) is connected with actuating unit by thimble rod and is installed on the mounting base (2), and entire mechanism is fixed on the mould body (5) by mounting base (2).

The actuating unit (1) that described promotion thimble moves is an oil cylinder or with motor-driven propulsive mechanism or pneumatic mechanism.

The utility model advantage is the goods one-shot forming, need not carry out secondary operations again, guaranteed the globality of goods, solved the phenomenon of leakage fluid dram place wall unevenness, leakage fluid dram end face and the interior cleanliness factor of the vertical and goods in its axle center have been guaranteed, it is more reliable that valve is installed, and shortened the production cycle of goods, improved efficient.Specifically, solved following technical problem:

1. solve the phenomenon of leakage fluid dram place wall unevenness;

2. save secondary operations technology;

3. avoid secondary to add caused cut surface and leakage fluid dram axle center out of plumb;

4. solve the plastic processing powder and fall into formation pollution in the container;

The danger that causes when 5. avoiding manually moulding being installed and the reduction of production efficiency;

6. avoid the bonding unreliability of moulding.

The specific embodiment

The special-purpose blow mold of a kind of plastics bulk container, has the mould body, it is to blow to container leakage fluid dram position the otch edge of a knife 4 is installed on the mould body, simultaneously is fixed with on the position and can moving and head into the leakage fluid dram thimble notching mechanism of the otch edge of a knife to the plastics otch moulding of container leakage fluid dram place being positioned at recessing tool mouth 4 on the mould body.

Plastics bulk container leakage fluid dram thimble notching mechanism in the above-mentioned mould, it comprises mounting base 2, thimble 3, the otch edge of a knife 4 and promotes the actuating unit 1 that thimble moves, thimble 3 is connected with actuating unit by thimble rod and is installed on the mounting base 2, and entire mechanism is fixed on the mould body 5 by mounting base 2.

The actuating unit 1 that described promotion thimble moves is an oil cylinder the best.Oil cylinder is fixed on the mounting base, guarantee enough strokes, when plastics propelled the price of, when plastics blew to this leakage fluid dram position, thimble was under the drive of oil cylinder, run to the incision in the otch edge of a knife, the otch knife-edge part has the flash groove of depression, stores unnecessary side cut material, and takes out of when taking out with goods, as shown in Figure 4, leakage fluid dram place plastics are carried out the otch moulding.

Employing machining is made, and sets up independently fluid pressure line and control system on the blow moulding machine.

Use: keeping on the former technology basis of goods blow molding, selecting the suitable time to increase thimble and eject technological action, and getting final product at suitable time increase thimble withdrawal technological action.
