Installation site
A hot chamber die-casting machine mold is an important piece of equipment used to inject and shape molten metal materials.
To achieve efficient and accurate production, the die-casting process needs to be standardized, and mold installation is an indispensable part of it. This article will introduce the problem of how to install the mold for customers in detail.
Mold inspection
Before installing the mold, the mold needs to be inspected. It mainly checks whether the appearance of the mold is intact and whether the parts are running in a normal state. If a problem is found, it needs to be repaired or replaced promptly.
Mold preparation
The mold is composed of multiple parts, and the larger components need to be split first. Disassemble the outer mold, inner mold, fixed plate, movable plate, mold spotter, mold partner, and other parts, and prepare the tools and screws required for installation.
Mold installation
Preparation of mold partner
Before the mold parter is installed, it is necessary to confirm the opening and closing status of the mold parter. Clean the lower parts and apply the right amount of lubrication to the correct position. Then insert the correct guide pillars separately to separate the upper and lower parts.
Preparation of fixed plate
Place the fixed plate on the rack, and determine the accurate positioning of the upper and lower molds of the fixed plate in advance. Arrange the clamp according to the size of the outer mold and the inner mold, insert the fixing plate into the mold spotter frame, and fix the plate on the frame with screws at the same time.
Preparation of movable plate
Lubricating oil is applied to the movable plate of the upper mold of the die-casting machine to ensure the accurate positioning of the outer mold and the inner mold; The parter should also be coated with an appropriate amount of lubricating oil, and the upper and lower parters should be combined.
Moldholder placement
Position the shape of the mold spotter frame and fix it, then insert the movable plate into the mold spotter frame, and fix it on the frame with screws.
Outer mold and inner mold device
Apply an appropriate amount of lubricating oil on the mold spotter frame, and place the outer mold in the mold spotter frame with a hoisting tool to ensure that the position of the outer mold is accurate.
Then the inner mold is installed on the outer mold to ensure that the space between the inner mold and the outer mold is reasonably allocated.
Installation base
The main plant arranges the die-casting machine, the holding furnace, and the auxiliary devices supporting the hot chamber die-casting machine (referred to as the main engine) and some peripheral equipment required; When it comes to the die-casting unit, it is equipped with the peripheral equipment required by the automated production line required for the products to be produced.
Laying cables and pipes should be equipped for various equipment and devices. The main line cable and main pipeline after the receiving plant, except for the overhead crane and the lighting cable placed above the overhead crane track, laying off the rest of the cables and pipes should be buried underground with protection.
This is especially true for branch cables and pipes connected to the machine to avoid interference with the transportation or peripheral equipment of the overhead crane. The outlet interface locations of all cables and pipes related to the main engine and equipment shall meet the requirements of the instructions of the die-casting machine, device, and equipment.
The die-casting machine and its supporting equipment and devices (hereinafter referred to as the machine, the same as the die-casting unit) are arranged according to the requirements.
The area of the machine should not only be in accordance with the requirements of the equipment manual but also should leave sufficient leeway.
When there are many machines and they are to be arranged together, they should be arranged differently according to the span of the plant.
When the method of replenishing molten metal from the melting furnace to the holding furnace is to use automatic transportation, whether it is above or on the ground, it cannot be placed within the space of the main passage, so as to ensure the safety and unobstructed flow of the main passage. It can not interfere with the operation of the overhead crane and the operation space of lifting.
The height of the main plant: the height of the crane needs to be lifted (including the maximum lifting of the largest mold, the maximum parts of the machine or equipment) to determine the position of the track surface of the crane and the height above the crane is determined according to the requirements of the building. Generally, for die-casting machines with a clamping force of less than 1000 tons, the height of the track surface of the overhead crane is about 8.5 m, and the height of the track surface of the overhead crane should be higher.
Environmental protection treatment devices should also be set up in the main plant, as well as facilities to maintain a healthy and good working environment for the plant. Among them, the exhaust ventilation system is the most critical, and the building structure and roof structure of the plant above the overhead crane should be adapted and matched with the requirements of the selected exhaust ventilation system.
Transport of the machine

After the installation is completed, it should be checked again, and then powered on to test and check whether there is any abnormal condition.
Clean up the mechanical body and the surrounding environment, remove the maintenance card, and notify the on-site production.
Cleaning-up the machine
If the die-casting machine needs to be shut down for a long time, the whole machine should be cleaned up, and a layer of anti-rust oil should be applied to the template, slide, steel belt, continuing column, piston rod, and other places that are easy to rust.
When dismantling the mold and hammer cooling water, stand on the side to prevent the high-temperature water vapor in the pipe from spraying out and hurting people.
It is strictly forbidden to flush the die-casting machine with water to avoid rust and an electrical short circuit of the equipment.
Only nitrogen is allowed to be filled in the accumulator, and it is strictly forbidden to fill oxygen or other gases into the accumulator to prevent explosion accidents. when disassembling the energy storage, the internal nitrogen must be vented.
Installation of casting push-off unit
One of the three major parts of die-casting peripheral automation equipment (pick-up machine, soup feeder, sprayer).
The die-casting picker is a mechanical equipment that realizes mechanical equipment that realizes mechanical equipment that picks the product from the mold and sends the product to the product safety area according to the ideal trajectory after the product is clamped from the mold through the mechanical connecting rod principle. It can be single-acted, or it can be connected with die-casting machines, sprayers, and soup feeders to form fully automatic production.
