Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a multi-layer mold equipment for molding composite materials. Background Technology

[0002] When manufacturing products in the factory, material forming molds ensure that injection molded products have highly accurate dimensions. The mold cavity and core are precision machined to control dimensional deviations within a very small range, so that the outer shell and internal electronic components are perfectly matched, ensuring the assembly accuracy and performance of the equipment. When manufacturing products with complex shapes, these can be molded in one go, ensuring the consistency and aesthetics of the products. At the same time, the automated production of material forming molds reduces manual operation, lowers labor costs, and improves the stability and consistency of production.

[0003] When mass production of the same product is required, multi-layer injection molds typically have multiple cavities, allowing for the simultaneous injection molding of multiple products. This significantly increases output per unit time. For complex multi-layer products, such as plastic containers with special functional layers and multi-layer plastic sheets, multi-layer molds can achieve simultaneous injection molding of each layer, reducing production steps and time, thereby improving overall production efficiency. Multi-layer injection molds play a vital role in modern industrial production, providing an effective technical means for producing high-performance, multi-functional plastic products.

[0004] Existing multi-layer molds used for material forming can cause the outer surface of the formed product to stick to the inner cavity of the mold during long-term operation. This requires manual separation of the product from the mold with the help of tools, which wastes extra labor. Prolonged processing can also cause the mold itself to overheat, resulting in excessively long forming time for the raw materials inside and extending the production cycle. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layer mold equipment for composite material molding, which aims to improve the problem of slow molding of raw materials in the mold due to temperature in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-layer mold equipment for composite material molding includes a mold base and a mold cover. Multiple positioning rods are fixedly connected to the top corner of the mold base. Multiple mold plates are arranged on the outer sides of the positioning rods. Multiple mold cavities are opened at the top of the mold plates. Temporary storage grooves are opened at the bottom of the inner walls of the mold cavities. Multiple spring cavities are opened inside the mold plates. Pressure strips are slidably connected to the inner walls of the spring cavities. Multiple pressure blocks are arranged at the top of the mold plates. The bottoms of the multiple pressure blocks penetrate the mold plates and are fixedly connected to the corresponding pressure strips. The outer walls of the pressure strips penetrate the temporary storage grooves and are fixedly connected to a release plate. The release plate fits into the inner wall of the temporary storage groove. Multiple positioning springs are fixedly connected to the bottom of the pressure strips. Limit plates are fixedly connected to the left and right sides of the bottom of the pressure strips. A heat dissipation mechanism is provided at the top of the mold plates for dissipating heat from the multi-layer mold.

[0008] As a further description of the above technical solution:

[0009] The heat dissipation mechanism includes a cooling fan, which is fixedly connected to the top of the mold cover. An air inlet is provided on the rear side of the mold plate, and a diversion groove is provided on the inner wall of the air inlet. A heat dissipation groove is connected to the front side of the diversion groove. An air outlet is provided on the rear side of the mold plate. The heat dissipation groove is connected to the air inlet through the diversion groove, and the other end of the heat dissipation groove is connected to the air outlet. Multiple heat-conducting rods are fixedly connected to the inner wall of the heat dissipation groove.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the positioning rod is provided with a threaded groove, and a fixing screw is threadedly connected to the top of the outer wall of the positioning rod.

[0012] As a further description of the above technical solution:

[0013] A threaded block is fixedly connected to the top of the mold cover, and a threaded injection pipe is threadedly connected to the inner wall of the mold cover.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the threaded injection tube is fixedly connected with a disassembly screw, and a feeding hole is opened at the bottom of the threaded injection tube.

[0016] As a further description of the above technical solution:

[0017] The mold plate has an injection hole at the top center, and the inner wall of the injection hole has multiple distribution holes. The other end of the distribution holes is connected to the inner cavity of the mold.

[0018] As a further description of the above technical solution:

[0019] The mold plate is fixedly connected to handles on both the left and right sides, and multiple positioning holes are provided at the top corner of the mold plate.

[0020] As a further description of the above technical solution:

[0021] The bottom of the mold base is fixedly connected with multiple suction cup feet, and the top corner of the mold cover is provided with multiple positioning holes.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the raw material is formed, the upper mold plate is removed so that the pressure block below is no longer under pressure, thereby releasing the tension of the spring below the pressure bar, allowing the pressure bar to slide upward in the spring cavity. When the pressure bar slides upward, it will drive the end plate to move upward, pushing out the processed product, thus avoiding the need for manual separation of the product from the mold.

[0024] 2. In this utility model, when the raw material is injected into the mold through the threaded injection pipe at the top, the cooling fan on the mold cover is turned on. The cooling fan blows room temperature air into the air inlet, and then the air is diverted into the diversion groove of each layer of the mold in the air inlet, thereby entering the heat dissipation grooves opened around the mold. The heat stored in the heat dissipation grooves is blown out through the air outlet by the continuously entering room temperature air, thereby achieving the heat dissipation effect of each layer of the mold.

[0035] See attached document Figure 2 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides a multi-layer mold equipment for composite material molding, including a mold base 1 and a mold cover 12. Multiple positioning rods 3 are fixedly connected to the top corner of the mold base 1. Multiple mold plates 4 are provided on the outer side of the positioning rods 3.

Multiple spring cavities 25 are opened inside the mold plate 4. Pressure strips 5 are slidably connected to the inner wall of the spring cavity 25. Multiple pressure blocks 9 are provided on the top of the mold plate 4. The bottom of each pressure block 9 passes through the mold plate 4 and is fixedly connected to the corresponding pressure strip 5. The outer wall of the pressure strip 5 passes through the temporary storage groove 10 and is fixedly connected to the ejector plate 7. The ejector plate 7 fits into the inner wall of the temporary storage groove 10. Multiple positioning springs 6 are fixedly connected to the bottom of the pressure strip 5. Limit plates 8 are fixedly connected to the left and right sides of the bottom of the pressure strip 5. A heat dissipation mechanism 2 is provided on the top of the mold plate 4. The heat dissipation mechanism 2 is used to dissipate heat for the multi-layer mold.

[0036] Specifically, four positioning rods 3 are fixedly connected to the top of the mold base 1. The positioning rods 3 are used to position the multiple mold plates 4 above. The mold plates 4 have four spring cavities 25 inside. When the pressure bar 5 inside the spring cavity 25 is pressed down by the pressure block 9, the whole will slide downward. At this time, the ejector plate 7 connected to the end of the pressure bar 5 will also move downward and fit with the temporary storage groove 10 below. At this time, the surface of the mold cavity 11 will remain flat. When the pressure block 9 does not contact the pressure above, the three positioning springs 6 below the pressure bar 5 will release the stress upward. At the same time, the pressure bar 5 slides upward. At this time, the ejector plate 7 at the end will also move upward, thereby ejecting the product formed on the inner wall of the mold cavity 11, so that the formed product is separated from the mold cavity 11.

[0037] See attached document Figure 3 Appendix Figure 5 and attached Figure 6 An embodiment of this utility model is provided: the heat dissipation mechanism 2 includes a heat dissipation fan 201, which is fixedly connected to the top of the mold cover 12.

The heat dissipation groove 205 is connected to the air inlet 202 through the diversion groove 203. The other end of the heat dissipation groove 205 is connected to the air outlet 204. A plurality of heat-conducting rods 206 are fixedly connected to the inner wall of the heat dissipation groove 205. A threaded block 14 is fixedly connected to the top of the mold cover 12. A threaded injection pipe 15 is threadedly connected to the inner wall of the mold cover 12.

[0038] Specifically, when the multi-layer mold is filled with raw materials, the cooling fan 201 fixed on the top of the mold cover 12 is turned on, blowing room temperature air into the air inlet 202 below. The air entering the air inlet 202 is diverted to the diversion groove 203 opened on each layer of mold plate 4, and then enters the heat dissipation groove 205 connected to the diversion groove 203. The multiple heat conduction rods 206 connected inside the heat dissipation groove 205 will conduct the heat inside the mold cavity 11 to the heat dissipation groove 205, and then be replaced by the room temperature air blown out by the cooling fan 201, and finally discharged from the air outlet 204 connected to the end of the heat dissipation groove 205.

[0039] See attached document Figure 1 Appendix Figure 6 and attached Figure 7 In one embodiment of this utility model: the outer wall of the positioning rod 3 is provided with a threaded groove 21, the top of the outer wall of the positioning rod 3 is threaded with a fixing screw 13, the top of the mold cover 12 is fixedly connected with a threaded block 14, the inner wall of the mold cover 12 is threaded with a threaded injection tube 15, the outer wall of the threaded injection tube 15 is fixedly connected with a disassembly screw 16, and the bottom of the threaded injection tube 15 is provided with a feeding hole 24.

[0040] Specifically, the threaded grooves 21 on the outer wall of the four positioning rods 3 engage with the fixing screws 13 at the top to fix the multi-layer mold plates 4 below. The threaded block 14 fixed above the mold cover 12 is rotated and fixed with the threaded injection tube 15. The feeding hole 24 at the bottom of the threaded injection tube 15 is used to feed the raw material into the mold.

[0041] See attached document Figure 1 Appendix Figure 4 and attached Figure 7 In one embodiment of this utility model: a material injection hole 17 is provided at the top center of the mold plate 4, and a plurality of material distribution holes 18 are provided on the inner wall of the material injection hole 17. The other end of the material distribution hole 18 is connected to the inner cavity 11 of the mold. Handles 20 are fixedly connected to both the left and right sides of the mold plate 4. A plurality of positioning holes 23 are provided at the top corner of the mold plate 4. A plurality of suction cup feet 19 are fixedly connected to the bottom of the mold base 1. A plurality of positioning holes 22 are provided at the top corner of the mold cover 12.

[0042] Specifically, the injection hole 17 and the distribution hole 18 in the middle of the mold plate 4 are used to guide and fill the raw materials into the mold cavity 11. The positioning holes 1 22 and 23 at the four corners of the mold plate 4 and the mold cover 12 are used for positioning. The handles 20 fixed on both sides of the mold plate 4 can be easily removed. The suction cup feet 19 fixed under the mold base 1 can stabilize the equipment.

[0043] Working principle: The mold plate 4 has four spring cavities 25 inside. The pressure block 9, which is farthest from the mold plate 4, protrudes from the surface of the mold plate 4. When the mold plate 4 is subjected to pressure from above, the pressure block 9 will be subjected to downward pressure first. At this time, the inner pressure bar 5 will slide downward as a whole. The ejector plate 7 connected to the end of the pressure bar 5 will also move downward and fit with the temporary storage groove 10 below. At this time, the surface of the inner cavity 11 of the mold will remain flat. When the pressure block 9 is not in contact with the pressure from above, the three positioning springs 6 below the pressure bar 5 will release the stress upward. At the same time, the pressure bar 5 will slide upward. At this time, the ejector plate 7 at the end will also move upward, thereby ejecting the product formed on the inner wall of the inner cavity 11 of the mold.

[0044] Furthermore, when the raw material fills the inner cavity 11 of the mold, the cooling fan 201 fixed on the top of the mold cover 12 turns on and blows room temperature air into the air inlet 202 below. The air entering the air inlet 202 will be diverted to the diversion grooves 203 opened on each layer of mold plate 4, and then enter the heat dissipation grooves 205 connected to them. The multiple heat-conducting rods 206 connected inside the heat dissipation groove 205 will conduct the heat inside the inner cavity 11 of the mold to the heat dissipation groove 205, and then be replaced by the room temperature air blown out by the cooling fan 201. Finally, it is discharged from the air outlet 204 connected to the end of the heat dissipation groove 205, thus completing the cooling effect of the mold itself.
