Description

Technical Field

[0001] The utility model relates to the technical field of pulp moulds, in particular to a pulp hot pressing mould. Background Art

[0002] The pulp hot pressing mold is an important tool for manufacturing pulp molded products. During the use of the pulp hot pressing mold, in order to increase the speed of removing water vapor inside the paper and plastic products, an exhaust hole is opened on the aluminum alloy bottom surface of the mold, and then the air is exhausted through an external vacuum machine. During the use of such a structure, it is necessary to exhaust air from the exhaust holes distributed at the bottom of the base. Since the bottom space of the aluminum alloy base is limited, it is extremely inconvenient to operate the exhaust and the space is relatively limited. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a pulp hot pressing molding die. By cooperating with the hot pressing molding die installation assembly and the hot pressing molding die assembly, the exhaust direction can be adjusted while retaining the exhaust holes distributed at the bottom. Several exhaust holes can be exhausted from the side at the same time, which is convenient for exhaust operation and avoids space restrictions. The exhaust holes cooperate with the breathable steel layer frame to increase the water vapor extraction speed inside the paper and plastic products.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a pulp hot pressing molding die, comprising:

[0005] A hot pressing mold installation assembly, the hot pressing mold installation assembly comprising an aluminum alloy base, a lower mold frame fixed to the top of the aluminum alloy base, a hydraulic rod arranged at the top of the aluminum alloy base, an aluminum alloy top plate connected to the top of the hydraulic rod, and a mold upper frame connected to the bottom of the aluminum alloy top plate;

[0006] A hot pressing mold assembly, the hot pressing mold assembly includes a mold cavity opened in the lower mold frame, a breathable steel layer frame welded in the mold cavity, an exhaust hole opened on the bottom surface of the aluminum alloy base, an exhaust outer frame arranged below the exhaust hole, an exhaust pipe connected to both sides of the exhaust outer frame and a rectangular notch opened on the bottom surface of the aluminum alloy base.

[0007] As a preferred solution of the pulp hot pressing forming mold described in the utility model, the depth of the rectangular notch is less than the frame depth of the vacuum outer frame;

[0008] Wherein, the frame of the air extraction outer frame and the rectangular notch are fitted into each other.

[0009] As a preferred solution of the pulp hot pressing forming mold described in the utility model, there are a plurality of air extraction holes, and the air extraction outer frame covers the plurality of air extraction holes.

[0010] As a preferred solution of a pulp hot pressing molding mold described in the utility model, it also includes a self-locking component, which includes a limiting base plate fixed on the bottom surface of the vacuum outer frame and a rectangular opening opened on the top surface of the limiting base plate.

[0011] As a preferred solution of the pulp hot pressing forming mold described in the utility model, the self-locking component also includes a rectangular touch plate with one end located in the rectangular opening and an L-shaped metal hook connected to the rectangular touch plate.

[0012] As a preferred solution of the pulp hot pressing forming mold described in the utility model, the self-locking component also includes a round rod passing through the L-shaped metal hook and arranged in the rectangular opening, and a long opening opened on the surface of the aluminum alloy base.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The utility model achieves the adjustment of the exhaust direction while retaining the exhaust holes distributed at the bottom through the cooperation of the hot pressing forming mold installation assembly and the hot pressing forming mold assembly. A plurality of exhaust holes can be exhausted simultaneously from the side, which is convenient for exhaust operation and avoids space restrictions. The exhaust holes cooperate with the breathable steel layer frame to improve the cooling effect.

[0015] 2. Based on the first beneficial effect, by setting up a self-locking component, the mold is self-locked by utilizing the gravity of the entire mold, thereby avoiding the situation where the vacuum outer frame is not stable enough due to shaking after being fitted with the rectangular notch.

[0016] 3. Based on the first beneficial effect, the breathable steel layer frame and the inner cavity of the mold are metallurgically combined together by brazing to eliminate the gap, instead of being clamped together. Clamping will produce air gaps, while metallurgical bonding will not produce gaps, thereby affecting heat transfer, and complex shapes are very difficult to clamp together.

[0017] During specific use, the rectangular groove and the exhaust outer frame fit together, and the aluminum alloy base can be supported by the exhaust outer frame. Since the depth of the rectangular groove is less than the frame depth of the exhaust outer frame, there is a height difference between the aluminum alloy base and the exhaust outer frame. The exhaust pipe extends directly from the side, so that the user uses a vacuum pump to connect the exhaust pipe to exhaust air outside. The exhaust outer frame covers the surface of several exhaust holes, and several exhaust holes are connected to the exhaust outer frame. Air is concentratedly exhausted through the exhaust pipe, and the contact space is limited, which is convenient for exhaust operation. The breathable steel layer frame cooperates with the exhaust holes to further improve the air permeability and increase the water vapor extraction speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model provides a pulp hot pressing forming mold. Through the cooperation of the hot pressing forming mold installation component and the hot pressing forming mold component, the exhaust direction can be adjusted while retaining the exhaust holes distributed at the bottom. A plurality of exhaust holes can be exhausted simultaneously from the side, which is convenient for exhaust operation and avoids space restrictions.

[0028] Example 1

[0029] Figure 1 , Figure 2 and Figure 3 The figure shows the overall structure of a pulp hot pressing mold according to the present invention. Figure 1 , Figure 2 and Figure 3 The main structure of this embodiment includes: a hot pressing mold installation component and a hot pressing mold component.

[0030] The hot pressing mold installation assembly is used in conjunction with the hot pressing mold assembly. Specifically, the hot pressing mold installation assembly includes an aluminum alloy base 11, a lower mold frame 12 fixed to the top of the aluminum alloy base 11, a hydraulic rod 13 arranged at the top of the aluminum alloy base 11, an aluminum alloy top plate 14 connected to the top of the hydraulic rod 13, and a mold upper frame 15 connected to the bottom of the aluminum alloy top plate 14;

[0031] During specific use, the hot pressing mold assembly is installed and used based on the aluminum alloy base 11 and the lower mold frame 12. During use, the hydraulic rod 13 drives the aluminum alloy top plate 14 to move downward, directly driving the mold upper frame 15 and the lower mold frame 12 to close the mold.

[0032] The hot pressing mold assembly is used to facilitate the user to perform the air extraction operation and remove the space restriction. Specifically, the hot pressing mold assembly includes a mold cavity 21 opened in the lower mold frame 12, a breathable steel layer frame 22 inserted into the mold cavity 21, an air extraction hole 23 opened on the bottom surface of the aluminum alloy base 11, an air extraction outer frame 24 arranged below the air extraction hole 23, an air extraction pipe 25 connected to both sides of the air extraction outer frame 24, and a rectangular notch 26 opened on the bottom surface of the aluminum alloy base 11;

[0033] During specific use, the rectangular groove 26 and the air extraction outer frame 24 fit together, and the aluminum alloy base 11 can be supported by the air extraction outer frame 24. Since the depth of the rectangular groove 26 is less than the frame depth of the air extraction outer frame 24, there is a height difference between the aluminum alloy base 11 and the air extraction outer frame 24. The air extraction pipe 25 extends directly from the side, so that the user can use a vacuum pump to connect the air extraction pipe 25 to extract air. The air extraction outer frame 24 covers the surface of several air extraction holes 23, and several air extraction holes 23 are connected to the air extraction outer frame 24. The air is concentratedly extracted through the air extraction pipe 25, and the contact space is limited, which is convenient for the air extraction operation. The breathable steel layer frame 22 cooperates with the air extraction holes 23 to further improve the air permeability and increase the water vapor extraction speed.

[0034] Example 2

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , through the self-locking component, the mold is self-locked by utilizing the gravity of the entire mold, so as to avoid the situation that the vacuum outer frame 24 and the rectangular notch 26 are not stable enough after shaking;

[0036] Specifically, it also includes a self-locking component, which includes a limiting base plate 31 fixed to the bottom surface of the air extraction outer frame 24 and a rectangular opening 32 opened on the top surface of the limiting base plate 31;

[0037] The self-locking assembly also includes a rectangular touch plate 34 with one end located in the rectangular opening 32, and an L-shaped metal hook 35 connected to the rectangular touch plate 34;

[0038] The self-locking assembly also includes a round rod 33 that passes through the L-shaped metal hook 35 and is disposed in the rectangular opening 32, and a long opening 36 opened on the surface of the aluminum alloy base 11;

[0039] When the user moves the aluminum alloy base 11 downward to fit the rectangular slot 26 with the vacuum outer frame 24, the aluminum alloy base 11 directly presses on the surface of the rectangular touch plate 34, pressing the rectangular touch plate 34 downward. The rectangular touch plate 34 is rotated by the round rod 33 under the force. At this time, the rectangular touch plate 34 moves downward, driving the L-shaped metal hook 35 to shift and lock it to the top surface of the aluminum alloy base 11 to prevent the aluminum alloy base 11 from shaking.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
