Description

Technical Field

[0001] This utility model relates to the field of flue production technology, and in particular to a synchronous flue extrusion molding device. Background Technology

[0002] With the continuous upgrading of flue equipment, the quality of flues has been continuously improved. However, when mass-producing flues, it is difficult for any flue equipment to meet the national standard for resistance to flexible impact testing. To solve this problem, rapid extrusion molding is required during flue production, and automatic demolding of the outer mold is necessary to achieve mass production of flues that meet national standards. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a synchronous flue gas extrusion molding device that enables the outer mold and inner mold to move in the same direction and synchronously, thereby achieving rapid extrusion molding and demolding.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] A synchronous flue gas extrusion molding device includes an inner mold and an outer mold assembly. The inner mold and the outer mold assembly cooperate to form a semi-enclosed cavity with an open top, resembling a "U". The inner mold moves up and down coaxially within the outer mold assembly. The top of the outer mold assembly has a feed port. The outer mold assembly includes an outer mold frame. Arc-shaped guides are fixedly installed around the top of the outer mold frame. A synchronous belt is wound around the arc-shaped guides. The synchronous belt forms the outer frame of the semi-enclosed cavity. A support seat is provided at the center of the outer mold assembly. The four sides of the support seat are fixed to one end of the synchronous belt. The support seat and the synchronous belt move up and down synchronously.

[0006] A hopper is provided at the feed inlet.

[0007] The sidewalls of the inner mold are hollow cavity structures, and a vacuum pump is connected to the hollow cavity structure through a pipe.

[0008] The arc-shaped guide is a semi-circular steel plate.

[0009] The arc-shaped guide component is a roller.

[0010] The bottom end of the inner mold is positioned by engaging with the support base through a positioning slot.

[0011] A counterweight is installed at the other end of the synchronous belt.

[0012] Angle steel is provided between the sides of the four synchronous belts, and the angle steel is fixed on the outer mold frame.

[0013] A chain plate is fixed below the synchronous belt, and the two sides of the chain plate are enclosed by angle steel inside the angle steel, so that the sides of the synchronous belt fit together tightly.

[0014] The inner mold slides up and down on the inner mold frame via a slide rail.

[0015] Compared to existing technologies, the advantages of this invention are as follows: This invention achieves positioning by inserting the inner mold into the outer mold assembly and engaging the inner mold with the support base. The mixed material is fed into the hopper, the vacuum pump is activated, and the inner mold and synchronous belt move downwards simultaneously. At this time, the material adheres to the perimeter of the inner mold, achieving compact compression. After the product is formed, the motor is activated again to drive the inner mold and synchronous belt upwards, thereby achieving automatic separation and demolding of the synchronous belt. Repeating the above operations allows for the rapid mass production of flues that meet national standards. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0023] like Figure 1-3 As shown, a synchronous flue gas extrusion molding device includes an inner mold and an outer mold assembly. The inner mold and the outer mold assembly cooperate to form a semi-enclosed cavity with an open top, resembling a "U". The inner mold moves up and down coaxially within the outer mold assembly. The top of the outer mold assembly has a feed port. The outer mold assembly includes an outer mold frame. Arc-shaped guides are fixedly installed around the top of the outer mold frame. A synchronous belt is wound around the arc-shaped guides. The synchronous belt forms the outer frame of the semi-enclosed cavity. A support seat is provided at the center of the outer mold assembly. The four sides of the support seat are fixed to one end of the synchronous belt. The support seat and the synchronous belt move up and down synchronously.

[0024] A hopper is provided at the feed inlet.

[0025] The sidewalls of the inner mold are hollow cavity structures, and a vacuum pump is connected to the hollow cavity structure through a pipe.

[0026] The arc-shaped guide component is a roller.

[0027] The bottom end of the inner mold is positioned by engaging with the support base through a positioning slot.

[0028] A counterweight is installed at the other end of the synchronous belt.

[0029] Angle steel is provided between the sides of the four synchronous belts, and the angle steel is fixed on the outer mold frame.

[0030] A chain plate is fixed below the synchronous belt, and the two sides of the chain plate are enclosed by angle steel inside the angle steel, so that the sides of the synchronous belt fit together tightly.

[0031] The inner mold slides up and down on the inner mold frame via a slide rail.

[0032] Working process: In the initial state, the inner mold is located above the hopper, the support base is located on the upper part of the outer mold assembly, and four synchronous belts surround the outer mold. First, the inner mold and the support base are positioned by the positioning slots. While the inner mold, support base, and synchronous belts move downward, material is injected into the hopper. The material enters the outer mold surrounded by the four synchronous belts through the feed port. While the inner mold descends, the vacuum pump is turned on. Under the action of the vacuum pump, the material is adsorbed around the inner mold, and excess water in the material is sucked out. During the descent of the inner mold, the inner mold and the synchronous belts work together to squeeze the material. After the product is initially formed, the inner mold moves upward under the action of the power device, which at the same time drives the support base to move upward. Since one end of the synchronous belt is fixed to the support base and the other end is equipped with a weight, the synchronous belt also drives the roller to rotate synchronously as the support base moves upward, thereby realizing the automatic demolding of the outer mold surrounded by the synchronous belts. Example 2

[0033] like Figure 1 , 4 As shown in Figure 5, a synchronous flue gas extrusion molding device includes an inner mold and an outer mold assembly. The inner mold and the outer mold assembly cooperate to form a semi-enclosed cavity with an open top. The inner mold moves up and down coaxially within the outer mold assembly. The top of the outer mold assembly is provided with a feed port. The outer mold assembly includes an outer mold frame. Arc-shaped guides are fixedly installed around the top of the outer mold frame. A synchronous belt is wound around the arc-shaped guides. The synchronous belt surrounds the outer frame of the semi-enclosed cavity. A support seat is provided at the center of the inner part of the outer mold assembly. The four sides of the support seat are respectively fixed to one end of the synchronous belt. The support seat and the synchronous belt move up and down synchronously.

[0034] A hopper is provided at the feed inlet.

[0035] The sidewalls of the inner mold are hollow cavity structures, and a vacuum pump is connected to the hollow cavity structure through a pipe.

[0036] The arc-shaped guide is a semi-circular steel plate.

[0037] The bottom end of the inner mold is positioned by engaging with the support base through a positioning slot.

[0038] A counterweight is installed at the other end of the synchronous belt.

[0039] Angle steel is provided between the sides of the four synchronous belts, and the angle steel is fixed on the outer mold frame.

[0040] A chain plate is fixed below the synchronous belt, and the two sides of the chain plate are enclosed by angle steel inside the angle steel, so that the sides of the synchronous belt fit together tightly.

[0041] The inner mold slides up and down on the inner mold frame via a slide rail.

[0042] Working process: In the initial state, the inner mold is located above the hopper, the support base is located on the upper part of the outer mold assembly, and four synchronous belts surround the outer mold. First, the inner mold and the support base are positioned by the positioning slots. While the inner mold, support base, and synchronous belts move downward, material is injected into the hopper. The material enters the outer mold surrounded by the four synchronous belts through the feed port. While the inner mold descends, the vacuum pump is turned on. Under the action of the vacuum pump, the material is adsorbed around the inner mold and excess water is sucked out. During the descent of the inner mold, the inner mold and the synchronous belts work together to squeeze the material. After the product is initially formed, the inner mold moves upward under the action of the power device, which also drives the support base to move upward. Since one end of the synchronous belt is fixed to the support base and the other end is equipped with a weight, the synchronous belt also moves synchronously along the semi-circular steel plate as the support base moves upward, thereby realizing the automatic demolding of the outer mold surrounded by the synchronous belts.

[0043] Similarly, the power unit in Example 1 can also be installed on a roller or a synchronous belt, and the power unit in Example 2 can also be installed on a synchronous belt. The downward movement of the inner mold relies on gravity, and the inner mold, support base and synchronous belt can also move together to extrude and mold the material automatically.
