After the Paint Bucket Mould is successfully designed, processed and debugged, it can be put into the production process. Correct use and maintenance are important factors to ensure continuous and continuous production of high-quality plastic products, and can also extend the service life of the paint bucket mold. Correct use and careful maintenance are of great significance to maintaining normal production and improving business efficiency.

  The operation of the paint bucket mold and the bucket mold is actually completed by the bucket forming machine, let us look at it together:

  1. Opening and closing speed and low voltage protection adjustment

  During the opening and closing of the barrel mold, the speed changes regularly, and there are three speed levels of "slow-fast-slow". In the process of closing the mold, in order to ensure that the mold plate can move without creeping, the system pressure of the moving mold plate is minimized before the bucket mold contacts.

  2. Adjustment of clamping force

  In normal production, the actual bucket will be gradually adjusted from low to high according to specific conditions. When ensuring that plastic products meet quality requirements, lower clamping force should be used as much as possible.

  3. Introduce system adjustment

  The launching mechanism of plastic products seriously affects the quality of plastic barrel products, and must be carefully and carefully adjusted to achieve the following aspects.

  3.1. Launch itinerary

  Make sure to eject the complete plastic product

  3.2. Number of shots

  Generally, plastic products with simple and deep depth can be set once, while plastic products with complex and deep depth can be set twice or even three times.

  3.3 Push speed

  The launch speed is related to the plastic raw material, the structure of the plastic product and the temperature of the mold. If the speed is too high to damage the plastic product, it should be adjusted from a low speed to a high speed to avoid damage to the plastic product.

  4. Bucket mold temperature control

  The temperature of the bucket mold is closely related to the molding material and must be strictly controlled. On the one hand, the accuracy of the temperature control table needs to be calibrated frequently. On the other hand, it is necessary to observe whether the working state of the instrument is normal and whether the cooling pipe is unblocked or in good condition to ensure the control accuracy of the mold temperature.

  5. Take out plastic parts

  The removal of molded products depends on the size of the plastic product, and there are three methods: automatic installation, manual removal and robotic removal. However, no matter what working method and picking method are used, it should be ensured that the workpiece and casting system must be thoroughly cleaned during each working cycle. Especially when the bucket machine is in a fully automatic operation state, it is necessary to set the "disassembly part" as a necessary condition for controlling the bucket machine to enter the next working cycle. Otherwise, once the part is left in the bucket mold, the bucket machine will execute the next clamping cycle. In most cases, the bucket mold will be damaged, and even the bucket mold will be seriously deformed and scrapped, so sufficient attention must be paid.

  6. Bucket mold cleaning

  In production, plastic products (such as burrs, scraps and carbides) are usually kept in the cavity of the bucket mold. At this time, the cavity of the bucket mold must be cleaned. The specific operation is as follows.

  1 Take the most time to dig the bucket mold, turn off the power of the hydraulic system of the forming mechanism and all power related to the side shaft, and then open the safety door for cleaning.

  2 The cleaning tool must be made of aluminum or copper. Do not use hard tools such as screwdrivers, boring cutters and wrenches to avoid damage to the cavity surface.

  3 Do not rub the surface of the bucket mold cavity with your hands, especially the mirror surface. If it is dirty, wipe it with a soft cotton cloth.

  Once Huaheng appears in the 4 cavity, it should be ground with a full-time bucket mold repair agent.

  7. Observe the working status of the bucket mold

  Observation of mold working status

  It should be observed from time to time whether the action sequence of the bucket mold is correct, whether the start and end positions, positioning, clamping, etc. of the core puller are accurate and reliable, and whether the sliding parts and guiding parts are correct. Severe wear and bite of the bucket mold, and whether the ejector or return machine is stuck. If you have trouble living, rest or mobility, you should solve the problem immediately.

  8. Anti-rust

  Some materials may decompose due to thermal decomposition and produce corrosive gases, which can cause metal molds to rust, which usually occurs when the mold is suspended. Therefore, when you stop forming, you must wipe the bucket mold clean with a clean soft cloth and close the mold to prevent corrosion caused by gas generated around other bucket machines. When molding is stopped for a long time, the mold cavity should be wiped, rust inhibitor should be sprayed, the barrel mold should be closed, butter should be applied, and the gate should be closed.

  9. Unload the mold to the warehouse

  After the production of plastic products, the barrel mold is thoroughly cleaned, and the surface of the cavity, key components, movable parts and positions are accurately and thoroughly inspected. After damage, rust inhibitor should be used. Remove the bucket mold and lock it with the lock plate according to the reverse steps of installing the mold. Complete the various accessories matching the bucket mold, place it with the bucket mold, fill in the bucket mold usage record, and then put the bucket mold into the inventory.
