CONTENT OF THE UTILITY MODEL
[0003] In order to solve the above problems, the utility model provides a single station core brick forming equipment, which completes the preparation of core brick in the same station, reduces the equipment area, and reduces the equipment cost.
[0004] Therefore, the technical scheme of the utility model is as follows: a single station core brick forming equipment, comprising a base, a stand column is arranged on the base, an outer mold frame and a mold tortoise back are slidably installed on the stand column, and an upper mold inner core is installed below the mold tortoise back;An upper box body is arranged above the stand column, an upper mold auxiliary oil cylinder, an upper mold main oil cylinder and an outer mold frame oil cylinder are arranged in the upper box body, the upper mold auxiliary oil cylinder and the upper mold main oil cylinder drive the mold tortoise back to ascend and descend, and the outer mold frame oil cylinder drives the outer mold frame to ascend and descend;A lower mold core and a lower mold oil cylinder for driving the lower mold core to ascend and descend are arranged below the base.
[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: the lower mold core is located at the lowest position, the outer mold frame is lowered to cover the outer side of the lower mold core, and the outer mold frame and the lower mold core form a filling mold.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the outer mold frame is sleeved on the outer side of the lower mold core, the upper mold inner core is lowered to be inserted into the lower mold core, and the three form a forming mold.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a plurality of protrusions are arranged on the lower mold core, a groove for inserting the protrusions is arranged on the lower end surface of the upper mold inner core, at least one forming port is arranged in the middle of the outer mold frame, the outer mold frame is sleeved on the outer side of the lower mold core, the protrusions are arranged in the forming port, the upper mold inner core is inserted into the forming port, and the protrusions work in cooperation with the groove.
[0008] As a preferred scheme of the above scheme, a plurality of through holes are arranged on the lower end surface of the upper mold core, the upper mold core is connected with a vacuum suction device, and the through holes can be in a negative pressure state.
[0009] In the production process, the production steps are as follows:
[0010] 1. Filling stage:
[0011] During the filling, the lower mold core is lowered to the lowest position, and the outer mold frame is driven by the outer mold frame oil cylinder to be lowered to cover the lower mold core. At this time, the protrusion of the lower mold core is inserted into the forming port of the outer mold frame, and the two form a filling mold. Then, the external feeding device is used to start feeding the slurry into the space between the lower mold core and the outer mold frame, and the residual material on the surface of the lower mold core is removed.
[0012] 2. Pressure forming stage:
[0013] Since the volume of the upper mold main oil cylinder is too large, and the volume of the auxiliary oil cylinder is small and the movement speed is fast, the upper mold auxiliary oil cylinder is used to drive the upper mold main oil cylinder to move downward. In this way, the main oil cylinder can directly suck the oil in the oil tank, and the auxiliary main oil cylinder operates.
[0014] Therefore, during the forming, the upper mold auxiliary oil cylinder is started first to drive the upper mold core to be lowered to the lower surface to contact the surface of the slurry. Then, the upper mold main oil cylinder starts to work, and the upper mold main oil cylinder drives the upper mold core to continue to move downward to extrude the filled slurry. At the same time, the vacuum suction device is started, and the through holes of the upper mold core are in a negative pressure state to start vacuum pumping and vacuum water absorption.
[0015] According to the thickness of the core-pulling brick, the pressing time of the upper mold main oil cylinder is set. When it is determined that the finished product has been pressed, the upper mold main oil cylinder stops working. At this time, the vacuum suction device continues to work to maintain the vacuum suction state.
[0016] 3. Demolding stage:
[0017] After the pressing is completed, the finished product exists in the closed space formed by the outer mold frame, the upper mold core, and the lower mold core. Then, the lower mold oil cylinder, the outer mold frame oil cylinder, and the upper mold auxiliary oil cylinder are driven to move synchronously, so that the outer mold frame, the upper mold core, the lower mold core, and the formed core-pulling brick jointly rise until the lower mold oil cylinder can reach the highest point. Then, the lower mold oil cylinder is lowered to drive the lower mold core to the lowest position, so that the lower mold core and the protrusion leave the core-pulling brick, and the core-pulling movement is completed. At this time, the through holes of the upper mold core still maintain the negative pressure state to suck the core-pulling brick to prevent the core-pulling brick from falling.
[0018] 4. Finished product taking stage:
[0019] Through the external mechanical hand, a base plate is moved to the outer membrane frame directly below, then the outer membrane frame oil cylinder, the upper die auxiliary oil cylinder drive the outer membrane frame and the upper die inner core to rise to the highest point, and the vacuum adsorption equipment is closed, the vacuum adsorption in the upper die inner core is stopped, so that the core pulling brick finished product is demoulded.
[0020] Compared with the prior art, the beneficial effects of the utility model are that: the forming module is split into the lower die core, the outer membrane frame and the upper die inner core which can be independently lifted, and the lower die core, the outer membrane frame and the upper die inner core respectively form the filler mold, the forming and pressing mold, the feeding process, the pressing process and the core pulling process are completed in the same station, the equipment floor area is greatly reduced, and the mold investment is reduced; meanwhile, multiple forming equipment can share one feeding system and one material taking system, and production intensification is realized.
