Description

Technical Field

[0001] The present application relates to the technical field of mold manufacturing, and in particular to a hot pressing mold for high-efficiency pressing. Background Art

[0002] Hot press dies are currently key equipment in the hot press forming process and are widely used in various industries, including automotive, electronics, aerospace, construction, and packaging. Hot press forming is a process in which heated raw materials are pressed into a mold to form them into the desired shape.

[0003] After the workpiece is hot-pressed, it is usually necessary to perform a cooling process to ensure the performance and dimensional stability of the material. The workpiece is usually placed in the air and cooled to room temperature.

[0004] The above-mentioned prior art solutions have the following drawbacks: the cooling efficiency of the workpiece at room temperature is low. Utility Model Content

[0005] In order to improve the cooling efficiency of a workpiece after hot pressing the workpiece, the present application provides a hot pressing mold with high efficiency.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A high-efficiency hot pressing mold device includes a conveyor belt, a hot pressing station and a robotic arm arranged on a machine body. The robotic arm is used to clamp the workpiece that has completed hot pressing and demolding, and transfer the workpiece to the conveyor belt for transportation. The machine body includes a support plate and a spray pipe. The support plate is fixedly connected to the machine body, and the spray pipe is fixedly connected to the support plate. The spray hole on the spray pipe points to the workpiece transported by the conveyor belt; the spray pipe is connected to an external water source, and the external water source is used to provide water to the spray pipe.

[0008] By adopting the above solution, an external water source provides water to the spray pipe, and the spray pipe sprays water onto the surface of the workpiece. As the conveyor belt drives the workpiece to move, the surface of the workpiece is sprayed, thereby being able to cool the surface of the workpiece, thereby achieving the effect of improving the cooling efficiency of the workpiece.

[0009] Furthermore, it also includes a water tank, a water supply pipe and a driving component. Water is placed in the water tank. One end of the water supply pipe is inserted below the liquid level of the water tank. The other end of the water supply pipe is connected to the spray pipe. The driving component is connected to the water supply pipe. The driving component is used to assist the water supply pipe to pump the water in the water tank into the spray pipe.

[0010] Furthermore, it also includes a receiving bucket, a support frame and a return water trough, one end of the support frame is in contact with the ground, and the other end of the support frame is fixedly connected to the receiving bucket; one end of the return water trough is connected to the bottom wall of the receiving bucket, and the other end of the return water trough is connected to the top wall of the water tank. The return water trough is used to guide the water received by the receiving bucket after spraying and cooling the workpiece back into the water tank.

[0011] By adopting the above scheme, the driving component is used to pump the water in the water tank to the spray pipe, and then spray it to the surface of the workpiece through the spray pipe. The water after spraying the surface of the workpiece flows into the receiving bucket, and then flows back to the water tank through the return trough, thereby forming a cycle.

[0012] Furthermore, both sides of the return water tank are fixedly connected with heightened plates, and the heightened plates are used to prevent water from the return water tank from splashing out.

[0013] Furthermore, the top wall of each of the heightened plates is fixedly connected to a blowing cage, and a fan is fixedly connected inside each of the blowing cages, and the fan is used to cool the water in the return water tank.

[0014] By adopting the above solution, the fan can cool the water in the return water tank, thereby cooling the water that is recirculated into the water tank after spraying the workpiece surface, so that the water in the circulation process is continuously in a low temperature state, thereby improving the cooling efficiency of the workpiece.

[0015] Furthermore, connecting plates are fixedly connected on both sides of the machine body, and a rotating rod is provided on the connecting plate. Both ends of the rotating rod are rotatably connected to the connecting rod. The rotating plate is wrapped with absorbent cotton, which abuts against the workpiece and is used to absorb moisture on the surface of the workpiece.

[0016] By adopting the above solution, because the absorbent cotton is in contact with the workpiece, as the conveyor belt drives the workpiece to rotate, there is friction between the workpiece and the absorbent cotton, which in turn drives the rotating rod to rotate around the connecting plate, and then makes the absorbent cotton rotate synchronously with the rotation of the rotating rod, thereby absorbing the moisture on the surface of the workpiece.

[0017] Furthermore, guide plates are fixedly connected to both sides of the machine body, and the guide plates are inclined from the machine body toward the receiving bucket. The guide plates are used to guide the water after spraying and cooling the workpiece into the receiving bucket.

[0018] By adopting the above solution, the guide plate can guide the water used to spray and cool the workpiece into the receiving bucket.

[0019] Furthermore, a flow limiting plate is fixedly connected to the position where the receiving bucket communicates with the return water tank, and the flow limiting plate is used to limit the speed at which the water in the receiving bucket flows into the return water tank.

[0020] By adopting the above solution, the setting of the flow limiting plate can limit the flow speed of water flowing into the return water trough through the receiving hopper, thereby preventing the water from splashing out of the return water trough due to excessive water flow speed.

[0021] In summary, this application has the following technical effects:

[0022] By setting up this device, an external water source provides water to the spray pipe, and the spray pipe sprays water onto the surface of the workpiece. As the conveyor belt drives the workpiece to move, the surface of the workpiece is sprayed, thereby being able to cool the surface of the workpiece, thereby achieving the effect of improving the cooling efficiency of the workpiece;

[0023] By setting a driving part and a receiving bucket, the driving part is used to pump the water in the water tank to the spray pipe, and then spray it to the surface of the workpiece through the spray pipe. The water after spraying the surface of the workpiece flows into the receiving bucket, and then flows back to the water tank through the return trough, thus forming a cycle;

[0024] By setting up a fan, the fan can cool the water in the return water tank, thereby cooling the water that is recirculated into the water tank after spraying the workpiece surface, so that the water in the circulation process is continuously in a low temperature state, thereby improving the cooling efficiency of the workpiece.
