Description

Technical Field

[0001] The utility model relates to the technical field of ceramic powder pressing, in particular to a ceramic powder pressing and forming die. Background Art

[0002] Ceramic powder is a sintered product of one or more non-metallic minerals. It is prepared from natural mineral raw materials such as clay, quartz, feldspar, kaolin, corundum, etc. according to different formulas, and then processed, formed and fired into porcelain materials. The production of ceramic powder products requires multiple processes such as powder making, forming, sintering and post-processing. During the forming process, the powder material is placed in a mold and pressed under a certain pressure, which requires the use of a pressing mold.

[0003] Currently, when ceramic powder is pressed into a flat plate, an upper mold and a lower mold are used together. The upper mold is pressed into the lower mold filled with ceramic powder by the pressure head of a hydraulic press, pressing the ceramic powder into a flat square shape. This makes subsequent removal more laborious, and the positive mold needs to be turned upside down before the flat plate can be taken out. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] Therefore, the purpose of the present invention is to provide a ceramic powder pressing mold, in which a servo motor drives the screw to rotate, so that the connecting seat moves up and down along the outer side of the screw, thereby changing the height position of the upper mold, and facilitating the separation of the upper and lower molds. The upper mold is connected to the connecting seat by matching the groove with the convex seat, and is clamped in the positioning block and the positioning groove. The clamping connection method facilitates the separation of the upper mold and the connecting seat, and is convenient for subsequent replacement.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] The utility model provides a ceramic powder pressing mold, please refer to Figure 1-4 , including a base 100, a power component 200, an upper mold component 300 and a lower mold component 400;

[0031] Please continue reading Figure 1-3 , as a base 100 connected to the base, a limited sliding groove 110 is provided on the top of the base 100;

[0032] Please continue reading Figure 1-3 The power component 200 is connected to the base 100 and includes a bracket 210 threadedly connected to the top of the base 100. A servo motor 220 is screwed to the top of the bracket 210. The output end of the servo motor 220 is connected to a screw rod 221.

[0033] The servo motor 220 works, driving the screw rod 221 to rotate and provide lifting power;

[0034] Please continue reading Figure 1-4 The upper mold component 300 is connected to the screw rod 221 and moves synchronously with the power component 200, moving up and down along the outer side of the screw rod 221;

[0035] The upper mold component 300 includes a connecting seat 310 screwed onto the outer side of the screw rod 221, and the bottom of the connecting seat 310 is connected to the upper mold 320;

[0036] The bottom of the connecting base 310 is integrally formed with a protrusion 312, and the connecting base 310 is symmetrically provided with two sets of positioning grooves 313. The top of the upper mold 320 is provided with a groove 321 that slides with the protrusion 312, and the outer side of the upper mold 320 is integrally formed with a positioning block 322 that snaps into the positioning groove 313.

[0037] action:

[0038] Since the screw rod 221 is threadedly engaged with the connecting seat 310 and the rotation direction of the connecting seat 310 is restricted, when the screw rod 221 rotates, the connecting seat 310 moves up and down along the outer side of the screw rod 221, thereby changing the height position of the upper mold 320 (thread feeding action);

[0039] Furthermore, the upper mold 320 is connected to the connecting base 310 by engaging with the groove 321 and the protrusion 312, and is clamped together with the positioning block 322 and the positioning groove 313. The clamping connection method facilitates separation of the upper mold 320 and the connecting base 310, and facilitates subsequent replacement.

[0040] Furthermore, the outer side of the bracket 210 is integrally connected with a guide seat 211, and the bottom of the connecting seat 310 is provided with a guide groove 311 that slides with the guide seat 211;

[0041] Please continue reading Figure 1-3, the lower mold part 400 is connected to the base 100 and is arranged below the corresponding upper mold part 300;

[0042] The lower mold component 400 includes a lower mold 410 connected to the top of the base 100, a template 420 is slidably connected to the lower mold 410, and the bottom of the template 420 is rectangular and connected to multiple groups of compression springs 421. The bottom of the lower mold 410 is connected to a limiting slide 411 that slidably cooperates with the limiting slide groove 110. The limiting slide 411 slidably cooperates with the limiting slide groove 110 to connect the lower mold 410 and the base 100, so that the lower mold 410 can be easily disassembled from the base 100. In addition, the compression spring 421 cooperates with the template 420. After the die is pressed and formed, the compression spring 421 drives the template 420 to rebound and move upward, thereby assisting in ejecting the pressed finished material, which is convenient for subsequent operations.

[0043] Working principle: When the utility model is in use, the servo motor 220 works to drive the screw rod 221 to rotate, and the connecting seat 310 is screwed on the screw rod 221, and the rotation direction is restricted, so that when the screw rod 221 rotates, the connecting seat 310 moves up and down along the outer side of the screw rod 221, thereby changing the height position of the upper mold 320, which is convenient for the upper and lower mold separation. At the same time, the upper mold 320 is connected to the connecting seat 310 through the groove 321 and the protrusion 312, and is clamped together by the positioning block 322 and the positioning groove 313. The clamping connection method facilitates the separation of the upper mold 320 and the connecting seat 310, and is convenient for subsequent replacement;

[0044] In addition, the limiting slide 411 slides in cooperation with the limiting slide groove 110 to connect the lower mold 410 and the base 100, making it convenient to disassemble and assemble the lower mold 410 from the base 100. The compression spring 421 cooperates with the template 420. After the mold is formed, the compression spring 421 drives the template 420 to rebound and move upward, thereby assisting in ejecting the finished product after pressing, and facilitating subsequent operations.

In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
