Description

Coiling device

Technical Field

The utility model relates to a coiling device for an injection molding machine, in particular to a coiling device suitable for an injection molding machine with multiple components and multiple materials.

Background

With the popularization of new energy automobiles and the improvement of aesthetic feeling of human beings on automobile lamps, the demands of interior trim parts and tail lamps of multi-material combination are changing day by day. This requires that the mold be rotated continuously during one-time injection molding, so that different materials can be molded in the mold. The injection molding machine needs to supply water, oil, electricity, and gas to the mold, rotating along with the mold.

In the prior art, as shown in fig. 1, a rotary joint 12 is added behind a movable mold plate 11 of an injection molding machine to ensure that water, gas and oil are connected with a mold through the mold plate. The rotary joint 12 is internally provided with a rotary seal, so that the fluid inside each cavity can not pass through. When the rotary joint works, the rotary joint 12 is fixed on the movable template 11, the inner axle center rotates along with the rotary disc 13, an ultra-flexible and ultra-wear-resistant wire needs to be placed in the axle center to rotate, and corresponding electric signals are provided for the die

The disadvantages of this structural design:

(1) the precision and the sealing requirement of the interior of the rotary joint are high, the rotary joint needs to be imported, the price is high, and the shelf life cannot be guaranteed;

(2) when the cooling water of the mold is high-temperature steam or the pressure of the supplied oil pressure is too high, the rotary sealing ring is easy to damage, the service life is short, and frequent maintenance is needed. Meanwhile, the requirement on the environment for replacing the sealing ring is high, and the sealing ring is easy to be scrapped integrally after being installed;

(3) the universality is not high, and the required fluid of the die can not be changed after increasing;

(4) the ultra-soft ultra-wear-resistant wire is expensive, and the machine cost is increased.

Disclosure of Invention

The utility model provides a coiling device, which reduces the cost of the whole device and prolongs the service life of the device. Meanwhile, the universality is improved, and the requirements of different molds are met.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a around dish device, includes movable mould board, carousel, pivot, movable mould board side-mounting carousel, the carousel is connected with the pivot of movable mould board opposite side, a disc device is fixed to the pivot rear side, connect the tank chain on the disc device.

Further, a fixed support is additionally arranged on the other side of the movable template, and the fixed support is fixedly connected with a tank.

Further, the tank chain is in a U-shaped state when not operating.

Further, water, oil, an air pipe and an electric wire enter the rotating shaft through the inside of the tank chain.

Further, when the rotary plate rotates, the tank chain is wound on the circular plate to rotate.

The utility model has the beneficial effects that:

1. obviously reduces the cost of the machine and shortens the delivery cycle of the machine.

2. Increase the service life of the machine, reduce the maintenance time and create more value for customers

3. The universality is increased, the engineering design time is shortened, and the working efficiency is improved

4. Simple maintenance and low operation level along with the operation environment and workers

fig. 2 is a schematic structural view of the disk winding device of the present invention.

Detailed Description

The utility model is further described with reference to the following figures and examples.

As shown in figure 2, the disk winding device of the utility model comprises a movable template 1, a rotary disk 2, a rotary shaft 3, a disk device 4, a tank chain 5 and a fixed support 6.

The original rotary joint is cancelled, a coiling device is replaced, the integral coiling device and the rotary table 2 on the movable template 1 are fixed together and rotate together with the rotary table 2, and all water and oil gas are distributed to the edge of the rotary table 2 through the middle shaft. A disk unit 4 is fixed to the rear side of the rotary shaft 3, and the disk unit 4 is used to fix a tank chain 5. The required water, oil, gas and electric wires all enter the rotary shaft 3 through the inside of the tank chain 5. And a fixed bracket 6 is added on the other side of the movable template 1 to fix the tank chain 5. The tank chain 5 is in a U-shape when not in operation.

When the turntable 2 rotates, the tank chain 5 is wound around the disk 4 to rotate. The required oil pipe, water pipe, air pipe and electric wire are all in the tank chain 5 and will not interfere with other parts or be worn. The design of the rotating shaft 3 needs to be properly amplified, and more interfaces are reserved to meet the requirements of different molds. All joint seals adopt plane seals, and original rotary seals are cancelled.

The electric signal line that needs can walk in the tank chain, uses ordinary electric wire just can satisfy the use of machine.
