Description

Technical Field

[0001] The present invention relates to a functional material production equipment, and in particular to a composite new material production equipment applied in the field of new material production equipment. Background Art

[0002] New materials refer to structural materials with excellent properties and functional materials with special properties that have been recently developed or are being developed. In recent years, the new materials studied and developed in the world mainly include new metal materials, fine ceramics and optical fibers, etc. Structural materials mainly use their mechanical properties such as strength, toughness, hardness, elasticity, etc. Composite materials are composed of two or more materials with different properties through physical or chemical methods to form materials with new properties at the macroscopic (microscopic) level, such as new ceramic materials, amorphous alloys, etc.

[0003] The production equipment of the new ceramic material includes its molding equipment. After searching, for example, the specification of the patent publication number CN110978215B discloses a composite new material production equipment, whose structure includes an exhaust pipe, a tank body, a loose-leaf, a cylinder cover, a single-sided mold, a vacuum pump, a slurry tank, a molding and paving system, and a pressure reducing valve. A single-sided mold is arranged in the middle of the tank body, and a molding and paving system is arranged on the single-sided mold. The molding and paving system is mechanically connected to the vacuum pump through an exhaust pipe, one side of the tank body is movably connected to the cylinder cover through a loose-leaf, and a slurry tank is installed on one side of the outside of the tank body. The slurry tank is connected to the single-sided mold through a pipeline, and a pressure reducing valve is installed on the exhaust pipe. Through the action of the double-layer membrane of the first layer of membrane and the second layer of membrane, the first layer of membrane and the slurry spread on the single-sided mold are bonded, and air is extracted from between the two layers of membrane to reduce the influence of later air extraction on the flow of slurry. The symmetrical design of the pipe arrangement of the present invention extracts the internal air in both directions from both ends to avoid the slurry flowing due to the single-direction air extraction, which causes the new ceramic material formed by hot pressing to be uneven at the beginning and the end.

[0004] However, based on the above search and combined with the prior art, it is found that during the molding process of the existing new ceramic material production equipment, the air inside the mold is not easy to be emptied during the grouting process, which affects the quality of the ceramic finished product. Therefore, a composite new material production equipment is proposed to improve the above problem. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the existing new ceramic material production equipment is forming, the air inside the mold is not easy to be emptied during the grouting process, which affects the quality of the ceramic finished product.

[0006] In order to solve the above problems, the present invention provides a composite new material production equipment, including a lower mold with a lower mold cavity provided inside, an upper mold with an upper mold cavity provided inside and a grouting channel provided on the upper side, and also includes:

[0007] An exhaust seat, the circumference of which is slidably fitted with the inner walls of the lower mold cavity and the upper mold cavity, a first elastic compression member is vertically installed between the bottom end of the exhaust seat and the inner bottom end of the lower mold, and an exhaust channel communicating with the outside is arranged at the bottom end of the lower mold;

[0008] An exhaust block, the circumference of the exhaust block is slidably fitted with the inner wall of the grouting channel, a second elastic compression member is vertically installed between the lower end of the exhaust block and the upper end of the exhaust seat, and when the exhaust block is not subjected to external pressure, its upper end surface is flush with the upper opening of the grouting channel, the upper end of the exhaust seat is provided with a second receiving groove for completely receiving the exhaust block, and the inner bottom end of the second receiving groove is provided with an exhaust hole vertically penetrating the exhaust seat;

[0009] A limiting structure is provided between the exhaust block and the exhaust seat so that the exhaust block is stably located inside the second receiving groove;

[0010] After the mold is closed, slurry is injected into the lower mold cavity and the upper mold cavity from the grouting channel. The exhaust block moves downward to be stored in the second receiving groove under the extrusion of the slurry, and is stably located at the inner side of the second receiving groove under the limiting effect of the limiting structure. The air in the grouting channel is discharged to the lower side of the exhaust seat through the exhaust hole.

[0011] During the process of continuously injecting the slurry, the exhaust seat continues to move downward under the extrusion of the slurry, and the air in the space below the exhaust seat is completely discharged to the outside through the exhaust channel.

[0012] In the above-mentioned composite new material production equipment, through the coordinated arrangement of the exhaust block, the second elastic compression member, the exhaust seat, the first elastic compression member and the exhaust channel, when the slurry is started to be injected from the grouting channel, the exhaust block moves down to be stored in the second receiving groove under the squeezing action of the slurry, and is stably located on the inner side of the second receiving groove under the limiting action of the limiting structure, and the air in the grouting channel is squeezed by the exhaust block and discharged to the lower side of the exhaust seat through the exhaust hole. During the process of continuing to inject the slurry, the exhaust seat continues to move downward under the squeezing action of the slurry, and the air in the space below the exhaust seat is completely discharged to the outside through the exhaust channel, thereby eliminating the adverse effects of the air inside the mold on the quality of the ceramic finished product, and the structure is simple and easy to operate.

[0013] As a further supplement to the present application, the inner bottom end of the lower mold is provided with a first receiving groove for completely accommodating the first elastic compression component, and the inner bottom end of the second receiving groove is provided with a third receiving groove for completely accommodating the second elastic compression component; this prevents the elastic compression component from being in a state of excessive compression for a long time, thereby reducing its elastic performance and extending its service life.

[0014] As a further supplement to the present application, the limiting structure includes a wedge-shaped limiting block, a third elastic compression member and a limiting sliding hole arranged on the side wall of the second receiving groove;

[0015] The side end of the exhaust block is provided with a groove for sliding cooperation of the wedge-shaped limit block, and the wedge-shaped limit block is fixed to the inner wall of the groove by a third elastic compression member. When the exhaust block is received in the inner side of the second receiving groove until its upper end surface is flush with the upper end surface of the exhaust seat, the wedge-shaped limit block partially slides into the inner side of the limit sliding hole.

[0016] As a further supplement to the present application, a first push groove is provided at the side end of the upper mold, and a limiting push block is slidably installed on the inner side of the first push groove. One end of the limiting push block is slidably matched with the limiting sliding hole, and the other end of the limiting push block slides through the upper mold; when one end of the limiting push block is located in the limiting sliding hole, the exhaust seat can be limited; before the exhaust block moves down to be completely received in the second receiving groove, it can be ensured that the exhaust seat will not be forced to move downward.

[0017] As a further supplement to the present application, a multifunctional slider is installed on the inner side of the limiting slide hole for horizontal sliding. When the wedge-shaped limiting block and the multifunctional slider are abutted against each other until the limiting push block is completely received in the inner side of the first push groove, the end of the multifunctional slider away from the wedge-shaped limiting block is flush with the side end surface of the exhaust seat; before the exhaust block moves down to be completely received in the second receiving groove, one end of the limiting push block is located in the limiting slide hole to limit the exhaust seat, and when the exhaust block moves down to be completely received in the second receiving groove, the wedge-shaped limiting block squeezes the multifunctional slider under the action of the third elastic compression member, so that the multifunctional slider squeezes the limiting push block until the limiting push block is completely separated from the limiting slide hole. At this time, the limiting effect between the exhaust seat and the upper mold is released, and the exhaust seat can continue to move downward under the extrusion of the slurry.

[0018] As a further supplement to the present application, a limiting slider is provided at the side end of the multifunctional slider, and a limiting groove adapted to the limiting slider is provided on the side wall of the limiting sliding hole, so that the end of the multifunctional slider away from the limiting push block will not extend to the outside of the limiting sliding hole; thereby preventing the multifunctional slider from extending into the grouting channel to block the exhaust block from moving downward.

[0019] As a further supplement to the present application, a second push groove is provided at the bottom end of the inner side of the lower mold cavity, and a reset push block is slidably installed on the inner side of the second push groove. The end of the reset push block away from the inner side of the lower mold cavity slides through the lower mold. When the exhaust seat is in contact with the inner bottom end of the lower mold, the second push groove and the limiting slide hole are located on the same horizontal plane, and the multifunctional slider is inserted into the second push groove under the extrusion action of the wedge-shaped limiting block; to prevent the first elastic compression member from having too large an elastic force, causing the exhaust seat to move upward and squeeze the slurry in the mold outward from the grouting channel after the grouting is stopped.

[0020] As a further supplement to the present application, a limiting pressure cap is provided at the end of the reset push block away from the inner side of the lower mold cavity, so that the end of the reset push block close to the inner side of the lower mold cavity will not extend to the outside of the second push groove; thereby preventing the reset push block from entering the lower mold cavity and hindering the downward movement of the exhaust seat.

[0021] As a further supplement to the present application, protective sleeves are fixed to the outer walls of the lower mold and the upper mold. The protective sleeve on the lower mold is sleeved on the outer side of the reset push block, and the protective sleeve on the upper mold is sleeved on the outer side of the limit push block; accidental touch can be effectively avoided.

[0022] In summary, after the mold is closed, slurry is injected into the lower mold cavity and the upper mold cavity from the grouting channel, and the exhaust block moves down to be accommodated in the second receiving groove under the extrusion of the slurry, and the wedge-shaped limit block is inserted into the limit sliding hole for limitation under the action of the third elastic compression member, so that the exhaust block is stably accommodated in the second receiving groove, and the air in the grouting channel is discharged to the lower side of the exhaust seat through the exhaust hole, and before the exhaust block moves down to be completely accommodated in the second receiving groove, one end of the limit push block is located in the limit sliding hole to limit the exhaust seat, and when the exhaust block moves down to be completely accommodated in the second receiving groove, the wedge-shaped limit block squeezes the multifunctional slider under the action of the third elastic compression member, so that the multifunctional The slider squeezes the limiting push block until the limiting push block completely disengages from the limiting slide hole. At this time, the limiting effect between the exhaust seat and the upper mold is released. During the process of continuing to inject slurry, the exhaust seat can continue to move downward under the squeezing effect of the slurry, and the air in the lower space of the exhaust seat is completely discharged to the outside through the exhaust channel; when the exhaust seat moves down to a state in contact with the inner bottom end of the lower mold, the multifunctional slider is inserted into the second push groove under the squeezing effect of the wedge-shaped limiting block, so that the exhaust seat is stably limited at the inner bottom end of the lower mold, preventing the first elastic compression member from having too large an elastic force, which causes the exhaust seat to move upward to squeeze out the slurry in the mold from the grouting channel after the grouting is stopped.

[0034] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] The present invention provides a composite new material production equipment, please refer to Figure 1-9 It includes a lower mold 1 with a lower mold cavity 101 on the inner side, an upper mold 2 with an upper mold cavity 201 on the inner side and a grouting channel 202 on the upper side, and also includes an exhaust seat 3 and an exhaust block 5.

[0037] Among them, the surrounding side of the exhaust seat 3 is slidably fitted with the inner walls of the lower mold cavity 101 and the upper mold cavity 201, a first elastic compression member 4 is vertically installed between the bottom end of the exhaust seat 3 and the inner bottom end of the lower mold 1, and an exhaust channel 102 connected to the outside is provided at the bottom end of the lower mold 1, and the surrounding side of the exhaust block 5 is slidably fitted with the inner wall of the grouting channel 202, a second elastic compression member 6 is vertically installed between the lower end of the exhaust block 5 and the upper end of the exhaust seat 3, and when the exhaust block 5 is not subject to external pressure, its upper end face is flush with the upper orifice of the grouting channel 202, and a second receiving groove 301 is provided at the upper end of the exhaust seat 3 for completely accommodating the exhaust block 5, and an exhaust hole 303 vertically penetrating the exhaust seat 3 is provided at the inner bottom end of the second receiving groove 301, and a limiting structure is provided between the exhaust block 5 and the exhaust seat 3 so that the exhaust block 5 is stably located on the inner side of the second receiving groove 301.

[0038] Regarding the limiting structure, specifically, the limiting structure includes a wedge-shaped limiting block 7, a third elastic compression member 8 and a limiting slide hole 304 arranged on the side wall of the second receiving groove 301, and the side end of the exhaust block 5 is provided with a groove 501 for sliding cooperation with the wedge-shaped limiting block 7, and the wedge-shaped limiting block 7 is fixed to the inner wall of the groove 501 through the third elastic compression member 8. When the exhaust block 5 is received in the inner side of the second receiving groove 301 until its upper end face is flush with the upper end face of the exhaust seat 3, the wedge-shaped limiting block 7 partially slides into the inner side of the limiting slide hole 304.

[0039] The composite new material production equipment is configured by the coordination of the exhaust block 5, the second elastic compression member 6, the exhaust seat 3, the first elastic compression member 4 and the exhaust channel 102. After the mold is closed, when the slurry is injected from the grouting channel 202, the exhaust block 5 moves down to be received in the second receiving groove 301 under the extrusion of the slurry. The wedge-shaped limit block 7 is inserted into the limit sliding hole 304 under the action of the third elastic compression member 8 to limit the position, so that the exhaust block 5 is stably received in the second receiving groove 301. The air in the grouting channel 202 is squeezed by the exhaust block 5 and discharged to the lower side of the exhaust seat 3 through the exhaust hole 303. During the process of continuing to inject the slurry, the exhaust seat 3 continues to move down under the extrusion of the slurry, and the air in the space below the exhaust seat 3 is completely discharged to the outside through the exhaust channel 102, thereby eliminating the adverse effects of the air inside the mold on the quality of the ceramic finished product. The structure is simple and the operation is convenient.

[0040] Among them, the inner bottom end of the lower mold 1 is provided with a first receiving groove 103 for completely accommodating the first elastic compression component 4, and the inner bottom end of the second receiving groove 301 is provided with a third receiving groove 302 for completely accommodating the second elastic compression component 6, so as to prevent the elastic compression component from being in an over-compressed state for a long time and reducing its elastic performance, thereby extending its service life.

[0041] Among them, a first push groove 203 is set at the side end of the upper mold 2, and a limiting push block 11 is slidably installed on the inner side of the first push groove 203. One end of the limiting push block 11 slides with the limiting sliding hole 304, and the other end of the limiting push block 11 slides through the upper mold 2.

[0042] Based on the matching arrangement of the above structure, when one end of the limiting push block 11 is located in the limiting slide hole 304, the exhaust seat 3 can be limited, and before the exhaust block 5 moves down to be completely received in the second receiving groove 301, it can be ensured that the exhaust seat 3 will not be forced to move downward.

[0043] Among them, a multifunctional slider 9 is horizontally slidably installed on the inner side of the limiting slide hole 304. When the wedge-shaped limiting block 7 and the multifunctional slider 9 are abutted against each other until the limiting push block 11 is completely received in the inner side of the first push groove 203, the end of the multifunctional slider 9 away from the wedge-shaped limiting block 7 is flush with the side end surface of the exhaust seat 3.

[0044] Based on the coordination arrangement of the above structure, before the exhaust block 5 moves down to be completely received in the second receiving groove 301, one end of the limiting push block 11 is located in the limiting slide hole 304 to limit the exhaust seat 3. When the exhaust block 5 moves down to be completely received in the second receiving groove 301, the wedge-shaped limiting block 7 squeezes the multifunctional slider 9 under the action of the third elastic compression member 8, so that the multifunctional slider 9 squeezes the limiting push block 11 until the limiting push block 11 is completely separated from the limiting slide hole 304. At this time, the limiting effect between the exhaust seat 3 and the upper mold 2 is released, and the exhaust seat 3 can continue to move downward under the extrusion of the slurry.

[0045] Among them, a limiting slider 10 is arranged at the side end of the multifunctional slider 9, and a limiting slide groove 305 adapted to the limiting slider 10 is arranged on the side wall of the limiting slide hole 304, so that the end of the multifunctional slider 9 away from the limiting push block 11 will not extend to the outside of the limiting slide hole 304, thereby preventing the multifunctional slider 9 from extending into the grouting channel 202 to block the exhaust block 5 from moving downward.

[0046] A second push groove 104 is provided at the bottom inner side of the lower mold cavity 101 , and a reset push block 12 is slidably installed inside the second push groove 104 . The reset push block 12 slides through the lower mold 1 at the end away from the inner side of the lower mold cavity 101 .

[0047] When the exhaust seat 3 is in contact with the inner bottom end of the lower mold 1, the second push groove 104 and the limiting slide hole 304 are located on the same horizontal plane, and the multifunctional slider 9 is inserted into the second push groove 104 under the extrusion of the wedge-shaped limiting block 7, which can prevent the first elastic compression member 4 from having too large an elastic force, causing the exhaust seat 3 to move upward and squeeze the slurry in the mold outward from the grouting channel 202 after the grouting is stopped.

[0048] Among them, a limiting pressure cap is set at the end of the reset push block 12 away from the inner side of the lower mold cavity 101, so that the end of the reset push block 12 close to the inner side of the lower mold cavity 101 will not extend to the outside of the second push groove 104, thereby preventing the reset push block 12 from entering the lower mold cavity 101 and hindering the downward movement of the exhaust seat 3.

[0049] Among them, the outer walls of the lower mold 1 and the upper mold 2 are fixed with a protective sleeve 13. The protective sleeve 13 on the lower mold 1 is sleeved on the outer side of the reset push block 12, and the protective sleeve 13 on the upper mold 2 is sleeved on the outer side of the limit push block 11, which can effectively avoid accidental touch.

[0050] Working principle: After the mold is closed, slurry is injected from the grouting channel 202 into the lower mold cavity 101 and the upper mold cavity 201. The exhaust block 5 moves downward to be stored in the second receiving groove 301 under the extrusion of the slurry. The wedge-shaped limiting block 7 is inserted into the limiting sliding hole 304 under the action of the third elastic compression member 8 to limit the position, so that the exhaust block 5 is stably stored in the second receiving groove 301, and the air in the grouting channel 202 is discharged to the lower side of the exhaust seat 3 through the exhaust hole 303;

[0051] Before the exhaust block 5 moves down to be completely received in the second receiving groove 301, one end of the limiting push block 11 is located in the limiting sliding hole 304 to limit the exhaust seat 3. When the exhaust block 5 moves down to be completely received in the second receiving groove 301, the wedge-shaped limiting block 7 squeezes the multifunctional sliding block 9 under the action of the third elastic compression member 8, so that the multifunctional sliding block 9 squeezes the limiting push block 11 until the limiting push block 11 is completely separated from the limiting sliding hole 304. At this time, the limiting effect between the exhaust seat 3 and the upper mold 2 is released.

[0052] During the process of continuing to inject the slurry, the exhaust seat 3 can continue to move downward under the extrusion of the slurry, and the air in the space below the exhaust seat 3 is completely discharged to the outside through the exhaust channel 102. When the exhaust seat 3 moves down to a state in contact with the inner bottom end of the lower mold 1, the multifunctional slider 9 is inserted into the second push groove 104 under the extrusion of the third elastic compression member 8 and the wedge-shaped limit block 7, so that the exhaust seat 3 is stably limited at the inner bottom end of the lower mold 1, preventing the first elastic compression member 4 from having too much elastic force, causing the first elastic compression member 4 to move the exhaust seat 3 upward to squeeze the slurry in the mold outward from the grouting channel 202 after the grouting is stopped;

[0053] After the slurry dries and shrinks, the green body can be removed from the mold;

[0054] After cleaning the mold, close the mold to prevent external dust and other debris from falling into the mold cavity and contaminating it. Manually press the reset push block 12 so that the reset push block 12 squeezes the multi-functional slider 9 until the multi-functional slider 9 disengages from the second push groove 104. At this time, the exhaust seat 3 is reset upward under the elastic action of the first elastic compression member 4. Then press the limit push block 11 again so that the limit push block 11 continues to squeeze the multi-functional slider 9 until the multi-functional slider 9 squeezes the wedge-shaped limit block 7 out of the limit slide hole 304. At this time, the exhaust block 5 is reset upward under the elastic action of the second elastic compression member 6.

[0055] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
