Description

Technical Field

[0001] This utility model relates to the field of mica processing equipment technology, and in particular to a hot pressing forming system based on a double-layer hot pressing forming mold. Background Technology

[0002] The raw material for mica 3D molding parts is coated paper. In its production process, hot pressing mold is an essential device to process the raw material coated paper into the required shape of the finished product. The existing hot pressing mold structure is generally single-layer, that is, it consists of an upper mold and a lower mold to form a mold cavity. The coated paper placed in the mold cavity is processed into shape under heating. The finished product of the required shape can be obtained by opening it. This opening and closing can only process one set of products at a time, which has low production efficiency, is easy to cause energy waste, and cannot meet the demand for high production capacity. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention proposes a hot pressing system based on a double-layer hot pressing mold to improve hot pressing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hot pressing forming system based on a double-layer hot pressing forming mold, characterized in that the mold includes an upper mold, a lower mold, and a sandwich mold; the hot pressing forming system includes a frame, a conveyor roller conveyor mounted on the frame, a base support sliding on the conveyor roller conveyor, and a pressing mechanism mounted above the conveyor roller conveyor; the lower mold is supported by the base support; a carrier plate is fixedly mounted on each side of the frame in front of the pressing mechanism; a lifting platform is mounted on the carrier plate; and the sandwich mold is supported by two lifting platforms.

[0005] The molding mechanism includes a longitudinally arranged hydraulic cylinder. The push rod of the hydraulic cylinder is equipped with a gripper that can carry the upper mold. The bottom support carries the lower mold, and the sandwich mold is supported by a lifting platform.

[0006] The specific working process is as follows: The upper mold, lower mold, and sandwich mold are loaded separately by a forklift, and are carried by grippers, a base support, and a lifting platform, respectively. The base support, where the lower mold is located, moves online to the bottom of the sandwich mold. The cylinder controls the lifting platform to move downwards until the sandwich mold and the lower mold are snapped together and stacked. The lifting platform continues to move downwards, causing the lifting platform to disengage from the upper mold. The base support carries the lower mold and the sandwich mold to continue moving to the bottom of the upper mold. The hydraulic cylinder drives the upper mold to move downwards until the upper mold and the sandwich mold are snapped together and stacked. The grippers release the upper mold, completing the stacking and snapping of the upper mold, lower mold, and sandwich mold. Then, the three molds are moved to the pressing station to complete the heat pressing of the three molds. Finally, the mold is removed and the material is discharged, completing the one-time two-piece forming of the double-layer mold.

[0007] The fastening method between the upper mold and the sandwich mold, and between the lower mold and the sandwich mold, is achieved by setting guide holes on the sandwich mold and guide posts on the upper mold and the lower mold. This is the conventional practice.

[0008] The lifting platform and the sandwich mold are coordinated by setting up side rails on both sides of the sandwich mold that can rest against the lifting platform.

[0009] The hot-pressed mica material forming two sheets is filled in the mold cavity facing upwards in the lower mold and the mold cavity facing upwards in the sandwich mold, respectively.

[0010] The base is operated by a lead screw, which is threaded onto the base and rotatably connected to the frame. The lead screw is driven by a motor, enabling the base to move horizontally online.

[0011] This solution addresses the shortcomings of existing single-layer hot-press molding die structures, which suffer from low production efficiency and cannot meet the demands of high production capacity. It aims to improve production efficiency, save energy, reduce production costs, and enhance product competitiveness while ensuring product quality requirements. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 and Figure 2 As shown, the mold includes an upper mold 1, a lower mold 2, and a sandwich mold 3. The hot pressing forming system includes a frame 4, a conveyor roller 5 set on the frame 4, a base 6 sliding on the conveyor roller 5, and a pressing mechanism 7 set above the conveyor roller 5. The lower mold 2 is supported by the base 6. A carrier plate 8 is fixedly set on both sides of the frame 4 in front of the pressing mechanism 7. A lifting platform 9 is set on the carrier plate 8. The sandwich mold 3 is supported by two lifting platforms 9.

[0017] The molding mechanism 7 includes a longitudinally arranged hydraulic cylinder. The push rod of the hydraulic cylinder is equipped with a gripper. The gripper can carry the upper mold 1, the bottom support 6 carries the lower mold 2, and the sandwich mold 3 is supported by the lifting platform 9.

[0018] The specific working process is as follows: The upper mold 1, lower mold 2, and sandwich mold 3 are loaded by a forklift and carried by grippers, base 6, and lifting platform 9 respectively. The base 6, where the lower mold 2 is located, moves online to below the sandwich mold 3. The cylinder controls the lifting platform 9 to move downward until the sandwich mold 3 and the lower mold 2 are snapped together and stacked. The lifting platform 9 continues to move downward, so that the lifting platform 9 is disengaged from the upper mold 1. The base 6 carries the lower mold 2 and sandwich mold 3 to continue moving to below the upper mold 1. The hydraulic cylinder drives the upper mold 1 to move downward until the upper mold 1 and the sandwich mold 3 are snapped together and stacked. The grippers release the upper mold 1, completing the stacking and snapping of the upper mold 1, lower mold 2, and sandwich mold 3. Then, the three molds are moved to the pressing station to complete the heat pressing of the three molds. Finally, the mold is removed and the material is discharged, completing the one-time two-piece forming of the double-layer mold.

[0019] The fastening method between the upper mold 1 and the sandwich mold 3, and between the lower mold 2 and the sandwich mold 3, is achieved by setting guide holes on the sandwich mold 3 and guide posts on the upper mold 1 and the lower mold 2. This is the conventional practice.

[0020] The cooperation between the lifting platform 9 and the sandwich mold 3 is achieved by setting baffles on both sides of the sandwich mold 3 that can rest against the lifting platform 9.

[0021] The hot-pressed mica material forming two sheets is filled in the mold cavity facing upwards in the lower mold 2 and the mold cavity facing upwards in the sandwich mold 3, respectively.

[0022] The base support 6 is operated by a lead screw, which is threaded onto the base support 6 and rotatably connected to the frame 4. The lead screw is driven by a motor, enabling the base support 6 to move horizontally online.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
