Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foaming, in particular to a glue blocking head, a foaming plate and a foaming method. BACKGROUND

[0002] Foaming plate is usually a plate-shaped structure formed by filling foaming material in a metal sheet shell. Foaming plate has the advantages of light weight, easy installation, good heat insulation, sound insulation, fire resistance and the like, and has been widely used in various industries.

[0003] The current production process of foaming plate is as follows: the metal sheet shell is placed in a laminating machine, and foaming material is poured into the shell cavity.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application is more thoroughly and completely conveyed to those skilled in the art, and the scope of the present application is fully conveyed to those skilled in the art.

[0041] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0042] Example 1:

[0043] like Figures 1-4 As shown, the present invention provides a sealing head, which includes a snap-fit ​​portion 200 and a sealing portion 100. Specifically, the snap-fit ​​portion 200 and the sealing portion 100 can be an integral structure or a separate structure. The snap-fit ​​portion 200 and the sealing portion 100 are made of the same material, more specifically, they can be made of rubber. When the snap-fit ​​portion 200 and the sealing portion 100 are an integral structure, the sealing head is manufactured using an injection molding method.

[0044] The snap-fit ​​part 200 is used to snap onto the filling port 13 of the foaming space; the plugging part 100 is disposed on one side of the snap-fit ​​part 200, and the plugging part 100 is provided with a discharge port 1101. The discharge port 1101 is opened when the foaming material is filled. After the foaming material is filled, the discharge port 1101 contracts, causing the foaming material to be blocked in the foaming space.

[0045] In one specific embodiment, when the snap-fit ​​part 200 snaps onto the filling port 13 of the foaming space, the plugging part 100 is located within the foaming space. More specifically, the snap-fit ​​part 200 has a first cavity 220 in its middle, and the plugging part 100 has a second cavity 130. The first cavity 220 and the second cavity 130 communicate with each other, and the second cavity 130 communicates with the discharge port 1101. The process of filling the foaming material involves placing the foaming gun head in the first cavity 220 and the second cavity 130, causing the foaming gun head to open the discharge port 1101 to allow material to enter.

[0046] It should be noted that the contraction of the outlet 1101 is accomplished by the material itself, without the need for external force, which ensures the ease of use of the plugging head. Specifically, the plugging head is made of rubber, which has a certain elasticity. When the foaming material is poured in, the foaming gun head and the foaming material can expand the outlet 1101, causing the outlet 1101 to undergo elastic deformation. After the pouring is completed, the foaming gun head is removed, and the outlet 1101 automatically contracts without the action of external force, the opening becomes smaller, thus blocking the foaming material.

[0047] The rubber blocking head comprises a clamping portion 200 and a rubber blocking portion 100. The clamping portion 200 is used for clamping on the pouring port 13 of the foaming space, and the rubber blocking portion 100 is arranged on one side of the clamping portion 200. In use, the rubber blocking head is installed on the pouring port 13 from the outside to the inside of the pouring port 13, and the rubber blocking portion 100 is extended into the foaming space. After the rubber blocking head is installed, the foaming material is poured into the foaming space through the rubber blocking head. The rubber blocking portion 100 is provided with a discharging port 1101. The discharging port 1101 is opened when the foaming material is poured, and the discharging port 1101 is contracted under the action of the self tension after the foaming material is poured, so that the foaming material is blocked in the foaming space. The rubber blocking head has novel structure and low production cost, can prevent the foaming material from overflowing in the foaming process, is beneficial to guarantee the foaming quality of the foaming plate 1, and improves the enterprise benefit.

[0048] Further, the rubber blocking portion 100 comprises a plug 120 and a discharging portion 110. The discharging portion 110 is arranged on the side wall of the plug 120 and protrudes outward from the side wall of the plug 120.

One side of each of the discharging portions 110 converges at the center of the plug 120 and is connected with each other. The plurality of discharging portions 110 are uniformly distributed on the side wall of the plug 120 along the circumferential direction of the plug 120. Further, the discharging port 1101 on each of the discharging portions 110 is arranged along the radial direction of the plug 120, and one side of each of the discharging ports 1101 is connected with each other.

[0052] In a more specific embodiment, the discharge part 110 is arranged on the plug 120 in 5-7, each of which is cuboid structure, and the plurality of discharge parts 110 form a star-shaped structure on one side of the plug 120. Each of the discharge parts 110 is arranged in a mutually independent structure, which can make the discharge part 110 have a certain tension on the discharge port 1101, so that the discharge port 1101 can be stretched when discharging, and the discharge port 1101 can automatically shrink under the action of its own tension after the pouring material is completed.

[0053] In a more specific embodiment, the discharge part 110 is arranged on the plug 120 in 5-7, each of which is cuboid structure, and the plurality of discharge parts 110 form a star-shaped structure on one side of the plug 120. Each of the discharge parts 110 is arranged in a mutually independent structure, which can make the discharge part 110 have a certain tension on the discharge port 1101, so that the discharge port 1101 can be stretched when discharging, and the discharge port 1101 can automatically shrink under the action of its own tension after the pouring material is completed.

[0054] Further, the plug 120 is provided with a reinforcing member 300, which includes a sleeve ring 310 and reinforcing ribs 320. The shape of the sleeve ring 310 is adapted to the shape of the top of the plug 120, and the reinforcing ribs 320 are uniformly distributed along the circumferential direction of the sleeve ring 310. One end of each reinforcing rib 320 is fixed to the sleeve ring 310, and the opposite end extends along the axis of the sleeve ring 310.

[0055] The sidewall of the plug 120 is provided with a plurality of embedding grooves 1201 adapted to the reinforcing ribs 320, which are arranged along the height direction of the plug 120. When the reinforcing member 300 is arranged on the plug 120, the sleeve ring 310 is sleeved on the top of the plug 120 and is in interference fit with the plug 120. The reinforcing ribs 320 are nested in the embedding grooves 1201 and are in interference fit with the embedding grooves 1201.

[0056] The reinforcing member 300 can be made of ABS material, the collar 310 and the reinforcing rib 320 are integrated structure, produced by injection molding process. The reinforcing rib 320 is nested in the embedding groove 1201, improves the structural strength and tension of the plug 120, can prevent the deformation of the plug 120 due to external force.

[0057] In an embodiment, the outer wall of the clamping part 200 is provided with a first clamping groove 210, the clamping part 200 is clamped on the pouring port 13 of the foaming space through the first clamping groove 210, and the first clamping groove 210 is in interference fit with the pouring port 13 of the foaming space. The interference amount of the first clamping groove 210 and the pouring port 13 is 0.7mm-1mm. The first clamping groove 210 in interference fit improves the tightness of the installation of the clamping part 200 and the pouring port 13, and also guarantees the glue blocking capacity of the glue blocking head.

[0058] The shape of the first clamping groove 210 needs to be matched with the shape of the pouring port 13, for example, when the pouring port 13 is a square port, the clamping groove is also provided in square. The glue blocking head is suitable for various shapes of pouring port 13 and different sizes of pouring port 13. Since the clamping part 200 and the glue blocking part 100 are both made of elastic material, they can be compressed as needed, so that the glue blocking head can be installed in pouring ports 13 of different sizes.

In this way, the function of blocking glue can be realized, and the clamping part 200 can be recycled, saving costs.

[0071] Embodiment 3

[0072] As shown in the figure, this embodiment only describes the differences from embodiment 2, and the remaining technical features are the same as those of the above embodiment. Figures 5-6

[0073] In this embodiment, when the clamping part 200 and the glue blocking part 100 are in a split structure, the glue blocking part 100 is provided with a clamping ring 1202, and the clamping ring 1202 is fixed on the periphery of the glue blocking part 100.
