Description

a molding machine

technical field

The utility model relates to the technical field of molding sand molding, in particular to a molding machine.

Background technique

The role of the differential is to make the speed of the wheels on both sides different. When the car turns, for example, turning left, the center of the curve is on the left, and the track of the right wheel is longer than that of the left wheel in the same time, so the right The side wheel turns faster, and to achieve this effect, it must be adjusted through the differential. In the prior art, the outer casing of the differential gear is generally obtained by casting, which is to cast molten metal into a casting cavity suitable for the shape of the part, and after it is cooled and solidified, it is subjected to sanding treatment with a sanding device. for its subsequent processing. Before casting and pouring the product, it must be shaped according to the model of the product. Molding machine is a mold molding equipment used in the foundry industry. Its main functions are: filling sand, filling loose molding sand into the sand box; The method is to compact the loose molding sand in the sand box, so that the sand mold has the necessary strength in the process of handling and pouring; the mold is lifted, and the pattern is taken out of the compacted sand mold by using different mechanisms.

Most of the current molding machines use vibrating cylinders as the vibration source, and the noise generated during the vibration process is relatively large. When multiple molding machines work at the same time, it will cause very large noise pollution and cause immeasurable damage to the health of workers. In addition, in the actual production process, since the molding sand first loaded into the sand box is in the shape of high middle and low surrounding, after the molding machine completes the hydraulic pressure on the sand box, the first contact with the pressing plate is the height of the middle part. With higher molding sand, the sand mold after molding tends to be dense in the middle and loose around the periphery, resulting in uneven strength of the sand mold, and prone to sand mold collapse during handling or pouring.

Utility model content

In order to make up for the shortcomings of the prior art, the utility model provides a molding machine, which can effectively reduce the noise generated during the working process, and can vibrate in multiple directions to avoid the problem of uneven sand pressing, and the vibration is uniform and efficient.

In order to achieve the above object, the utility model provides the following technical solutions:

A molding machine, comprising a machine body, a workbench and a rocker device are arranged on the body, a pneumatic cylinder is arranged at the bottom of the workbench, a hydraulic cylinder is arranged above the rocker device, and a There is a telescopic rod, the lower end of the telescopic rod is provided with a pressure plate, and the feature is that the four top corners of the top surface of the pressure plate are provided with springs, and a vibration pressure plate is connected above the spring, and two vibration pressure plates are installed on the vibration pressure plate. For the eccentric motor, several pressing blocks are arranged on the lower end surface of the vibrating pressing plate, and there is a gap between the pressing blocks and the pressing plate.

Further, a circular through hole is provided in the middle of the vibrating pressure plate, and the vibrating pressure plate is provided on the periphery of the telescopic rod through the circular through hole.

Further, several of the pressing blocks are evenly distributed on the lower end surface of the vibrating pressure plate, and the number of the pressing blocks is an even number.

Further, the lower end surface of the workbench is provided with a sound-absorbing board.

Further, the hydraulic cylinder is fixedly connected to the pressure plate through the telescopic rod.

Further, the spring is fixedly connected to the pressing plate and the vibrating pressing plate through a connecting block.

By adopting the above technical scheme, the utility model has the following beneficial effects: the utility model is simple in structure, easy to use, the rocker arm device can rotate 360 degrees, convenient to replace the sand box, and flexible in processing; it adopts pneumatic cylinder, pressing plate, vibration pressing plate and pressing block And other devices vibrate and compact the casting sand up and down, the compactness and compacting efficiency of the casting sand are greatly improved, the finished products processed by the utility model are uniform, and the reject rate is low; Part of the noise generated can greatly reduce the noise pollution caused by vibration and provide a good working environment for workers.
