This creation is related to a mold assembly, especially a forming device for manufacturing raised floor and its formed raised floor casting.

At present, the semiconductor factories are equipped with raised floors with multiple micro-holes to clean the air quality of the environment and ensure the specifications of the clean room.

At present, the raised floor is made by die casting. In the molding process, molds are often used to produce the required products, and a release layer is applied to the mold before the molding operation is performed to facilitate subsequent demolding operations.

In the conventional process of making a raised floor, as shown in FIGS. 1A to 1C, a mold assembly 1 is provided, which includes a male mold 1a with a pattern P and a female mold 1b with a flat surface, wherein the pattern P is Used to form a honeycomb structure, and then press the male mold 1a and the female mold 1b; then, through a feed pipe 10, the material is supplied between the male mold 1a and the female mold 1b, and the material is solidified Then, a semi-finished raised floor 9 is formed, wherein the semi-finished raised floor 9 has opposite flat sides 9a and honeycomb sides 9b. After that, the ejector pin of the ejector die 1c is used to hit the male die 1a to loosen the semi-finished raised floor 9 so as to take out the semi-finished raised floor 9 from the male die 1a. Finally, a hole-forming operation is performed to form a plurality of perforations on the plane side 9a of the raised floor semi-finished product 9 to form the required raised floor, and the raised floor can use the airflow to remove fine dust through the perforations. The hole operation is performed with a drill bit, and after the hole forming operation is performed, a tile 8 can be pasted on the flat side 9a as required (as shown in FIG. 1D).

However, during the hole forming process, the thickness D (approximately 4~10mm) of the plane side 9a is too thick, as shown in Figure 1D, which greatly increases the drilling depth, which makes processing difficult and easily causes stress to concentrate on the honeycomb The side 9b causes the structure of the honeycomb side 9b to be broken.

Furthermore, the thickness D of the plane side 9a is too thick, and debris will be generated during the drilling process, which will make it difficult to remove the debris in the perforation subsequently, so that debris will remain in the perforation, so use the In the case of a raised floor, the perforations of the raised floor are prone to blockage and cannot remove fine dust.

Therefore, how to overcome the various problems of the above-mentioned conventional technology has actually become a problem that the industry urgently needs to overcome.

In the aforementioned forming device, the first mold is a male mold, which includes a first mold having the first pressing surface, an abutting member disposed on the first mold, and a bearing that carries the first mold. A module and a first supporting member of the abutting member such that the abutting member is located between the first module and the first supporting member, the first module serves as a mold core, and the first supporting member It has a groove for accommodating the mold core. For example, the abutting member is formed with a plurality of first pinholes penetrating the abutting member, and the first bearing member is formed with a plurality of second pinholes penetrating the first bearing member to make the second pinhole Align the first pinhole. Furthermore, an auxiliary mold with a plurality of thimble pins is included, so that the plurality of thimble pins should pass through the plurality of first pinholes and second pinholes.

And the separation distance t between the bottom surface 30a of the recess 30 and the ground side 3a is relatively thin, as shown in FIG. 4B-1, so that the separation distance t (approximately 1~3 mm) is much thinner than the plate body 3' (Or between the ground side 3a and the honeycomb side 3b as shown in Fig. 4B-1) the thickness D (about 4~10mm, or the thickness D of the conventional plane side 9a as shown in Fig. 1D), so Compared with the prior art, when the perforation 40 is formed at the recess 30, the thickness of the ground side 3a where the perforation 40 is scheduled to be formed (that is, the separation distance t) is extremely thin, resulting in a significant reduction in the depth of the hole, which is advantageous During processing, there will be no stress concentration problem on the ground side 3a and/or the honeycomb side 3b, so as to avoid the problem of structural fragmentation on the ground side 3a and/or the honeycomb side 3b, thereby improving the raised floor 4 The production yield and reliability.

Furthermore, by reducing the spacing distance t (approximately 1~3mm), the punching method can be used during the hole forming process, so that the punches used for forming the hole generate very little debris, and during the punching process In this case, the punch will simultaneously rush the debris out of the perforation 40 in a direction away from the perforation 40, so that no debris will remain in the perforation 40, so dust will not be generated and cause environmental pollution problems.

In addition, since the position of the perforation 40 is aligned with the position of the recess 30, the punch for the hole forming operation can be aligned with the position of the recess 30 to perform the hole forming action before the hole is formed, so the punch can be moved from the honeycomb side 3b passes toward the ground side 3a, and rushes out the debris, thus avoiding the problem of the debris remaining in the perforation 40, so that the perforation 40 of the raised floor 4 can effectively avoid clogging and can be completed quickly Piercing operation.
