Description

A square sand box support frame for resin sand molding Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a square sand box support frame for resin sand molding. Background Technology

[0002] When designing product processes and making molds, based on the product structure shown in the drawings, it is necessary to use the core-hanging process when necessary. That is, all clay cores and molds are in the upper box. After the clay cores are assembled, the upper box needs to be turned upside down and connected to the lower box to complete the mold assembly of the entire mold. When the upper box is turned upside down, the clay cores in the upper box need to be fixed on the sand box. Otherwise, when the sand box is turned upside down, the clay cores will fall down due to gravity. Only by fixing them can they be prevented from falling downside down.

[0003] In existing technologies, fixing the core requires screws to be tightened, and the operation needs to be carried out from below the sand box. During the operation, the sand box is lifted by a hoisting device, and then workers operate from below. This method of use is highly dangerous, as workers can be injured if the rope breaks. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem in the existing technology of fixing the core of the resin sand, which requires screw fastening and operation from below the sand box. During operation, the sand box is lifted by a hoisting device and then the worker operates from below. This method is highly dangerous, as the worker may be injured if the rope breaks. Therefore, a square sand box support frame for resin sand molding is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a square sand box support frame for resin sand molding, comprising a bearing base, a side support frame fixedly connected to the lower end of the bearing base, a reinforcing rib fixedly connected between the side support frame and the bearing base, a base fixedly connected to both sides of the lower end of the side support frame, a rubber pad fixedly connected to both sides of the lower end of the base, a reinforcing rod fixedly connected inside the side support frame, and a groove for the sand box to mate with the bearing base being opened at the bottom. A fan can be used during operation, with the fan mainly facing the bearing base to cool the bearing base, side support frame, and reinforcing rib, reducing metal fatigue caused by high temperatures. The rubber pad is made of high-temperature resistant silicone.

[0006] Preferably, an end plate is fixedly connected to the upper middle part of the base.

[0007] Preferably, an extension sleeve is fixedly connected to the middle of the upper end of the reinforcing rod, and a threaded hole is opened inside the extension sleeve, with an adjusting bolt threaded inside the threaded hole.

[0008] Preferably, the base is slidably connected to an inner support plate, and omnidirectional wheels are fixedly connected to both sides of the lower middle part of the inner support plate.

[0009] Preferably, the base has bottom through grooves on both sides of the middle part at the lower end.

[0010] Preferably, guide plates are fixedly connected to the middle of both sides of the base, and guide grooves are opened in the middle of both sides of the inner support plate, and the guide grooves are slidably connected to the guide plates.

[0011] Preferably, a spring is fixedly connected between the lower middle part of the inner support plate and the base.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a support frame is formed by setting up a bearing seat, a side support frame and a base. During installation, the groove at the bottom of the sand box can be connected to the bearing seat, and the bearing seat supports the sand box. The reinforcing ribs can ensure the support strength, thereby improving the safety of fixing the mud core.

[0014] 2. In this utility model, by adjusting the bolt and the universal wheel, when movement is required, the universal wheel can be exposed from the bottom groove by rotating the adjusting bolt, so as to facilitate movement and use. By setting the guide plate and the guide groove, the movement position of the inner support plate is guided to ensure that the inner support plate falls vertically. By setting the spring, the inner support plate is pulled downward, which can reduce the force required to rotate the adjusting bolt, making operation easier and use more convenient.
