Embodiment 1

[0032] refer to figure 1 , figure 2 , an improved ceramic tile hydraulic molding core, including a core body 1, a primer layer 2 with a hardness of 70 degrees is provided on the pressure-bearing working surface of the core body 1, and a rubber layer 2 is provided above the primer layer 2. Layer 3, between the bottom rubber layer 2 and the rubber layer 3, there are a plurality of supporting columns 4 that play a supporting role and are connected with the bottom rubber layer 2 and the rubber layer 3, and the space between the bottom rubber layer 2 and the rubber layer 3 is a reservoir for containing oil. The oil space 5 ; the core body 1 is provided with an oil injection hole 61 and an oil drain hole 62 communicating with the oil storage space 5 . The oil injection hole 61 and the oil drain hole 62 are respectively sealed by a screw plug and a gasket, and the oil injection hole 61 is also provided with a one-way valve, (the screw plug, the gasket, and the one-way valve are not...

Embodiment 2

[0040] This embodiment is roughly the same as Embodiment 1, refer to Figure 4 , Figure 5 , Figure 6 , just change the support column 4 into a cylindrical shape and arrange it along the horizontal and vertical directions, and the adjacent support columns 4 are arranged at equal intervals, and the corresponding through holes 71 on the bracket 7 are also replaced with cylindrical through holes. The rest of the structure is the same as that of Embodiment 1, and will not be described in detail here.

Embodiment 3

[0042] This embodiment is roughly the same as Embodiment 1 and Embodiment 2, refer to Figure 7 , Figure 8 , the mold core body 1 includes a mold core steel body 1a made of No. 45 steel, a slope is provided on the periphery of the pressure-bearing working surface of the mold core steel body 1a, and a wear-resistant alloy is used on the slope of the mold core steel body 1a The electrode surfacing welding cutting edge 1b is formed to replace the integral chromium steel core body in the above embodiment. When the core body is partially damaged, especially the cutting edge, it can be repaired and reprocessed to avoid waste of resources and reduce costs. For other structures, refer to Embodiment 1 or Embodiment 2, and will not be described in detail here.

Abstract

The invention provides an improved tile oil-pressure forming block core, comprising a block core body. A rubber layer is arranged on a bearing operation face of the block core body; another rubber layer is arranged above the rubber layer; a plurality of supporting columns for supporting and connecting the two rubber layers are arranged between the two rubber layers; an oil storage space for containing oil is arranged between the two rubber layers; and an oil injection hole and an oil leakage hole which are communicated with the oil storage space are arranged on the block core body. Meanwhile, the invention further provides a production method of the block core, comprising the following steps that: primer is arranged on the bearing operation face of the block core body and a bracket with a through hole is arranged on the primer, and rubber is injected into the through hole; the other rubber layer is arranged on the upper surface of the bracket and the bracket is smelted to flow out from the oil injection hole and the oil leakage hole, so as to form the supporting columns connected with the upper rubber layer and the lower rubber layer. The production method of the improved tile oil pressure forming block core is smart and simple. Meanwhile, the surfaces of block core rubber layers have smaller fluctuation. And the pressed tile has high structural intensity and attractive appearance.

Description

technical field [0001] The invention relates to the technical field of tile moulds, in particular to an improved ceramic tile hydraulic molding core and a production method thereof. Background technique [0002] At present, the general-purpose rubber composite tile mold is mainly composed of a bottom plate, a buffer block, a middle frame and a mold core. The pressure-bearing working surface of the mold core is covered with a hard rubber layer. Due to uneven distribution or inconsistent powder, the pressed brick is easy Phenomena such as large and small heads, knife bends, waist shrinking, belly swelling, and interlayers appear. A relatively advanced oil-filled capsule-type equal positive pressure mold core. An oil-filled capsule body is arranged in the rubber layer of the mold core. There are connected oil grooves uniformly distributed in the oil-filled capsule body. The oil-filled capsule body is provided with an oil injection port and an oil drain port to the mold On the ...
