The current situation of the casting workshop of the horizontal parting off box injection molding machine

Including the body, the upper end of the body is connected with a feed port, the left and right sides of the body are connected with an exhaust port, the body is equipped with an upper box mechanism, the upper box mechanism is slidingly connected with the inner wall of the body, the bottom of the body is fixedly connected with a lower box mechanism, the lower box mechanism is slidingly connected with the inner wall of the body, the front side wall of the body near the right side is fixedly connected with a drive member, the drive member is fixedly connected with a template member, the template member is located between the upper box mechanism and the lower box mechanism. The utility model uses the first hydraulic cylinder to drive the upper box and the second hydraulic cylinder to drive the lower box, and the compressed air is used to shoot the sand evenly into the sand box, and the moulding is carried out by the moulding plate, and then the external pressure is applied to compact the moulding, so as to improve the speed of moulding. It is also possible to precisely locate and change the moulds without stopping the machine, thus improving the efficiency of the moulding process. The advantages of this machine are high accuracy of sand mould size, easy to lower the core, high productivity, less sand leakage, according to the height of the casting, you can choose horizontal sand injection and upper and lower sand injection, if the height of the casting is high, it is recommended to use the upper and lower sand injection horizontal parting box injection molding machine, the sand mould produced is higher.

According to the sand size, it can be divided into ZXJ5060, ZXJ6272, ZXJ6272A, ZXJ6565, ZXJ8080, ZXJ100100, equipped with sand processing from 20T/H-100T/H, because the sand box of horizontal parting off box injection molding machine is aluminum sand box, the quality of sand requirements are high, sand in the process of casting because the casting After the casting is cooled, the sand will be separated from the sand by vibrating sand falling machine, and the old sand will be mixed with cooled metal beans and flying burrs. Therefore, the old sand needs to be recycled：

Through the magnetic separation equipment to remove metal beans and flying edge burrs in the old sand, green sand bentonite after high temperature casting will solidify to produce lumps, after the piece of impact crusher on the old sand lump bentonite sand block, after the bucket elevator to transport the old sand to the sand screen to remove the old sand unusable lump bentonite, control the mud content of the old sand to ensure the fineness of the old sand, into the pre-storage sand storage for a short cooling process, in order to In order to match the molding speed of the horizontal parting off-box injection molding machine, it is necessary to ensure the supply of raw sand, so in the automated sand casting system will also be equipped with boiling cooling bed, the old sand for rapid cooling, after cooling the sand into the old sand sand storage, the old sand in the process of recovery and regeneration will have loss, the normal regeneration rate can usually reach more than 90%, so will be equipped with new sand storage combined with the old sand for proportional use The hardness, air permeability and humidity of the sand determine the integrity of the casting, the hardness of the sand produced by the horizontal parting off box injection molding machine can reach HB85-90, because the sand mixing quantity and quality of the sand mixing in the automatic foundry mixing machine are controllable, the raw sand in the sand bank needs to be added quantitatively through the grid quantifier or electronic scale in the process of entering the sand mixing machine, and the coal powder and bentonite in the auxiliary hopper are fed quantitatively through the screw feeder. The sand mixing cycle is about 3 minutes per pot. The mixed sand is conveyed to the storage tank above the moulding machine through the feeding belt, the amount of sand required for each moulding is fixed for the horizontal dividing and discharging injection moulding machine. After the sand enters the sand storage chamber, the sand is injected evenly into the sand box by compressed air, thus completing a sand filling.

The sand can be transported manually or automatically after the sand is launched from the machine. For large castings, there is a box press to ensure that the sand will not be scattered or broken during the casting process. The automatic casting system is divided into inclined casting and bottom casting, the running track is parallel to the sand conveying track, the pouring amount of iron is controlled each time, there is no waste and splash caused by manual casting, so the casting line using automatic casting line casting The effect of old sand recovery is much higher than that of manual casting line.

The side suction hood of the dust collector is opposite to the casting machine in the casting area. The metal ferrous liquid will produce a large amount of soot when entering the sand cavity of the sand, which will pollute the workshop environment if not treated in time, and the side suction hood will be discharged to the outside quickly through the negative pressure customer generated by the fan, and then discharged to the atmosphere after filtering by cloth bags. The top cover of GS high efficiency rotor sand mixer is equipped with dust collector connection port, which can remove the dust generated in the process of sand addition and mixing, in general, the dust collector runs through the whole casting workshop to purify the workshop environment.

After cooling, the sand type is conveyed to the vibrating sand falling machine through the conveying belt or stabbing box machine to complete the sand separation, and the castings are conveyed to the scale plate conveyor to remove the sprue through the vibrating sand falling machine, and the rough castings will be surface shot blasted through the shot blasting machine if they need shot blasting treatment.
