Description

Technical Field

[0001] This utility model relates to an electric porcelain blank pressing device with a blank ejection device. Background Technology

[0002] In the wet process of producing electrical porcelain, ceramic powder is placed into a flexible mold, covered with a leather cap and tightened. The flexible mold is then placed in a metal mold and hoisted into a pressure cylinder by a crane. After pressing, the entire piece is hoisted out of the cylinder, the cap is removed, the mold is demolded, and powder is poured in and the process is repeated. Each time, the entire metal mold must be hoisted in and out, which greatly increases the labor intensity and reduces efficiency. Moreover, the metal mold is made of steel and is very likely to hit the inner wall of the pressure cylinder during hoisting. If the inner wall of the pressure cylinder is damaged, it will destroy the high-pressure seal of the pressure cylinder.

[0003] Therefore, how to solve the problem of frequent entry and exit of metal molds is an urgent issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric porcelain pressing device with a blank ejection device. By adding an ejection cylinder at the bottom of the cylinder that can achieve ultra-high pressure dynamic sealing, the metal mold can be ejected. The entire cycle of powder filling, pressing and blank removal can be achieved without lifting the entire metal mold out of the cylinder, which greatly reduces labor intensity, improves production efficiency and realizes the automation of blank pressing.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A porcelain blank pressing device with a blank ejection mechanism includes a pressing cylinder, a gantry, a metal mold, a lifting seat, an ejection cylinder, a locking cylinder, a support, and a traveling system. The pressing cylinder, metal mold, lifting seat, ejection cylinder, locking cylinder, and support are embedded inside the gantry. The traveling system is longitudinally arranged at the bottom outer side of the gantry. The locking cylinder is located at the bottom inner side of the gantry. The metal mold is vertically arranged inside the pressing cylinder. The support is externally mounted on the outer side of the locking cylinder. The ejection cylinder is vertically mounted at the top center of the locking cylinder. The lifting seat is located outside the ejection cylinder, and its bottom is vertically mounted on the top surface of the support. The top surface of the lifting seat is fixedly connected to the bottom surface of the pressure cylinder. An ejector cylinder is provided through the center of the top surface of the lifting seat. The top surface of the piston rod of the ejector cylinder is engaged with the bottom surface of the metal mold. The metal mold is installed inside the pressure cylinder by moving up and down through the piston rod. After the metal mold is placed into the pressure cylinder, it can complete the cycle of powder filling, capping, cylinder head lowering, pressurizing, cylinder head raising, cap removal, blank removal, and powder filling without frequent lifting. It is only necessary to use the ejector cylinder to push the entire metal mold out of the cylinder above the height of the cylinder head to operate outside the cylinder. At the same time, with the addition of a robot, it can achieve full automation, greatly reducing labor intensity and improving the pressing efficiency.

[0007] Furthermore, the ejector cylinder is fixed on the lower cylinder cover of the pressure cylinder, the piston rod of the ejector cylinder passes through the lower cylinder cover, and the high-pressure dynamic seal is formed by a Y-ring and a triangular copper ring.

[0008] Furthermore, the ejector cylinder is embedded in the lifting seat, and the height of the ejector cylinder is lower than that of the lifting seat, so that the lifting seat transmits the vertical force.

[0009] Furthermore, the piston rod of the ejector cylinder extends a sufficient length at its shortest retracted position to position the metal mold, and its end has a guide taper.

[0010] Furthermore, the height of the ejector cylinder needs to be compatible with the height of the metal mold and the pressure cylinder, and the stroke of the ejector cylinder should be such that the metal mold is higher than the upper plane of the pressure cylinder for easy operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: after the metal mold is placed into the pressure cylinder, it can complete the cycle of powder filling, capping, cylinder cover lowering, pressurizing, cylinder cover raising, cap removal, blank removal, and powder filling again without frequent lifting out. It only needs to use the ejector cylinder to push the metal mold out of the cylinder above the height of the cylinder cover to operate outside the cylinder. At the same time, with the addition of a robotic arm, it can achieve full automation, greatly reducing labor intensity and improving the pressing efficiency. Attached Figure Description

[0017] like Figure 1-2This utility model discloses an electric porcelain blank pressing device with a blank ejection mechanism. Its features include a pressing cylinder 1, a gantry 2, a metal mold 3, a lifting seat 4, an ejection cylinder 5, a locking cylinder 6, a support 7, and a traveling system 8. The pressing cylinder 1, metal mold 3, lifting seat 4, ejection cylinder 5, locking cylinder 6, and support 7 are embedded inside the gantry 2. The traveling system 8 is longitudinally arranged at the bottom outer side of the gantry 2. The locking cylinder 6 is located at the bottom inner side of the gantry 2. The metal mold 3 is vertically arranged inside the pressing cylinder 1. The locking cylinder 6... A bracket 7 is provided on the outer side of cylinder 6. An ejector cylinder 5 is vertically mounted on the top center of the locking cylinder 6. An elevating seat 4 is provided on the outer side of the ejector cylinder 5. The bottom of the elevating seat 4 is vertically mounted on the top surface of the bracket 7. The top surface of the elevating seat 4 is fixedly connected to the bottom surface of the pressure cylinder 1. The ejector cylinder 5 is provided through the center of the top surface of the elevating seat 4. The top surface of the piston rod 51 of the ejector cylinder 5 is engaged with the bottom surface of the metal mold 3. The metal mold 3 is located inside the pressure cylinder 1 and moves up and down through the piston rod 51.

[0018] The lifting seat 4 sits on the support 7. A pressure cylinder 1 is installed above the lifting seat 4. A locking cylinder 6 is installed on the gantry 2. There is a small gap between the locking cylinder 6 and the lifting seat 4. The ejector cylinder 5 is installed on the lower cylinder cover of the pressure cylinder 1 and nested in the middle of the lifting seat 4. The metal mold 3 is hoisted into the pressure cylinder 1 as a whole. Guided by the tapered end of the piston rod 51 of the ejector cylinder 5, the ejector cylinder 5 is inserted into the piston rod 51 until the entire metal mold falls onto the lower cylinder cover of the pressure cylinder. The piston rod 51 of the ejector cylinder 5 extends, driving the metal mold 3 to rise to the upper cylinder cover of the ultra-high pressure cylinder 1. After the powder is filled and the cap is put on, the ejector cylinder retracts. The metal mold 3 is pulled down onto the lower cylinder cover of the pressure cylinder 1. The upper cylinder cover of the pressure cylinder 1 moves down into place. The gantry 2 moves above the pressure cylinder 1 under the traction of the walking system 8. The locking cylinder 6 first locks the lifting seat 4 and the pressure cylinder 1, and transmits the force to the gantry 2 to start the pressurization program. After the pressurization program is completed, the gantry 2 is pulled out and offset from the position of the pressure cylinder 1 under the traction of the walking system 8. The upper cylinder cover of the pressure cylinder 1 is opened, and the ejector cylinder 5 extends to drive the metal mold 3 to rise above the upper cylinder cover of the high-pressure cylinder 1. After the cap is removed and the blank is lifted out, the powder is poured in and the cycle is repeated. The entire process does not require the pressure cylinder 1 to be lifted in and out frequently.

[0019] Since the pressure inside the cylinder 1 is ultra-high, exceeding 100 MPa, and the piston rod 51 of the ejector cylinder 5 passes through the lower cylinder cover of the cylinder, forming a dynamic seal, the sealing requirements are extremely high. This utility model uses a combination of a Y-shaped ring 52 and a triangular copper ring 53 to jointly achieve ultra-high pressure dynamic sealing.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
