Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive block production, in particular to a mold for hot melt adhesive block production. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless and is an environmentally friendly chemical product. During the production process of hot melt adhesive, the raw materials need to be mixed and poured into a mixing bin for heating and dissolution. After mixing, the hot melt adhesive liquid is poured into the mold through the discharge port for shaping.

[0003] In the use of existing molds, before injecting molten hot melt adhesive into the mold, it is usually necessary to wrap the groove of the mold with release paper, which is mainly used to prevent the hot melt adhesive from adhering to the mold surface. Then, the glue liquid is poured into the groove wrapped with the release paper. After the glue liquid cools and solidifies, the staff removes the release paper wrapped with the hot melt adhesive block from the groove of the mold, and then folds the release paper to package the hot melt adhesive block as a whole. Finally, the packaged hot melt adhesive block is packed into boxes.

[0004] However, in actual use, since the solidified hot melt adhesive block has a certain weight, and there is a certain friction between the concavely laid release paper and the inner wall of the mold, the release paper is easily torn when the staff pulls the release paper to remove the hot melt adhesive block from the mold, which not only affects the demolding and packaging efficiency of the hot melt adhesive block, but also increases the company's production costs. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that workers easily tear the release paper wrapping the hot melt adhesive block when demoulding, which not only affects the demoulding and packaging efficiency of the hot melt adhesive block, but also increases the production cost of the enterprise. A mold for hot melt adhesive block production is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A mold for producing hot melt adhesive blocks includes a mold body with multiple grooves on the top, and a top plate slidably connected to the grooves; wherein, the bottom of the mold body is fixedly connected to a shell, and a lifting part is provided inside the shell, and the lifting part is used to drive the top plate to move up and down.

[0008] In order to facilitate the removal of the release paper wrapped with the hot melt adhesive block, preferably, the lifting part includes an electric push cylinder, which is fixedly installed in the shell, wherein a support plate is slidably installed inside the shell, and the bottom of the support plate is fixedly connected to the output end of the electric push cylinder, and a push rod is slidably connected to the mold body, and the bottom end of the push rod is fixedly connected to the top of the support plate, and the top plate is fixedly connected to the top of the push rod.

[0009] In order to improve the stability of the support plate when it moves, further, both sides of the inner wall of the shell are provided with sliding grooves, both sides of the support plate are fixedly connected with sliders, and the sliders are longitudinally slidably connected in the sliding grooves.

[0010] In order to reduce the risk of deformation of the hot melt adhesive block product, further, both sides of the mold body are fixedly connected with support plates, and blowing shells are fixedly installed on the facing surfaces of the support plates. Connecting plates are slidably installed on both sides of the shell, and the top of the connecting plate is fixedly connected with a telescopic airbag; the top of the telescopic airbag is fixedly connected to the bottom of the support plate, and both sides of the bottom of the telescopic airbag are connected with air inlet pipes, and the top of the telescopic airbag is connected to the blowing shell through an air supply pipe. One-way valves are installed in the air inlet pipe and the air supply pipe, and one side of the connecting plate is fixedly connected to the support plate.

[0011] In order to enable the connecting plate to slide longitudinally, further, both sides of the shell are penetrated with through openings, and the connecting plate is longitudinally slidably connected in the through openings.

[0012] In order to expand the blowing range, further, an air guide cover is fixedly connected to the blowing port of the blowing shell, and the air guide port of the air guide cover faces the top surface of the mold body.

[0013] In order to filter the air entering the telescopic airbag, a filter element is further detachably installed at the air inlet of the air inlet pipe.

[0014] In order to facilitate the inspection and maintenance of the electric push cylinder in the shell, preferably, an inspection port is opened through the surface of the shell, and a maintenance cover is detachably installed on the surface of the shell.

[0015] Compared with the prior art, the present invention provides a mold for producing hot melt adhesive blocks, which has the following beneficial effects:

[0016] 1. The mold for producing hot-melt adhesive blocks can quickly eject the release paper wrapped with the hot-melt adhesive block from each groove by starting the electric push cylinder and driving the support plate and the top plate to move upward, so as to achieve rapid demoulding and removal of the hot-melt adhesive block product. At the same time, during the demoulding process, the release paper will not be torn, ensuring the integrity of the release paper. This not only improves the demoulding and packaging efficiency of the hot-melt adhesive block, but also reduces the production cost of the enterprise.

[0017] 2. The mold for producing hot-melt adhesive blocks starts the electric push cylinder and drives the connecting plate to move upward through the support plate, so that the air in the telescopic airbag blows continuously toward the hot-melt adhesive block, which can cool the hot-melt adhesive block again during the process of ejecting the hot-melt adhesive block and the release paper. The flowing air takes away the residual heat on the hot-melt adhesive block, thereby reducing the residual heat on the hot-melt adhesive block, reducing the risk of deformation of the hot-melt adhesive block product, and indirectly improving the production quality of the product.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented using the prior art. The utility model solves the problem in the prior art that workers easily tear the release paper wrapping the hot melt adhesive block when demolding, which not only affects the demolding and packaging efficiency of the hot melt adhesive block, but also increases the production cost of the enterprise.

[0028] Example:

[0029] Reference Figures 1-6 An embodiment of the utility model provides a mold for producing hot melt adhesive blocks, including a mold body 1 with a plurality of grooves 2 on the top, the number of grooves 2 is 6-12, preferably 8, and linearly distributed on both sides of the top of the mold body 1, and also includes: a top plate 4, which is slidably connected in the grooves 2, and the number of top plates 4 is the same as the number of grooves 2; wherein, the bottom of the mold body 1 is fixedly connected to a shell 3, and a lifting part is provided inside the shell 3, and the lifting part is used to drive the top plate 4 to move up and down.

[0030] Specifically, during use, the setting of the lifting part can drive the top plate 4 to slide upward along the inner wall of the groove 2, and can quickly push out the release paper wrapped with the hot melt adhesive block from each groove 2, so as to realize the rapid demolding and removal of the hot melt adhesive block product. At the same time, during the demolding process, the release paper will not be torn, ensuring the integrity of the release paper, which not only improves the demolding and packaging efficiency of the hot melt adhesive block, but also reduces the production cost of the enterprise.

[0031] The lifting part includes: an electric push cylinder 5, which is fixedly installed in the shell 3, wherein a support plate 51 is slidably installed inside the shell 3, and the bottom of the support plate 51 is fixedly connected to the output end of the electric push cylinder 5. A push rod 52 is slidably connected to the mold body 1, and the bottom end of the push rod 52 is fixedly connected to the top of the support plate 51, and the top plate 4 is fixedly connected to the top of the push rod 52.

[0032] Specifically, by starting the electric push cylinder 5, the output end of the electric push cylinder 5 drives the support plate 51 and the push rod 52 to move upward, and drives the top plate 4 to slide upward along the inner wall of the groove 2, so that the release paper wrapped with the hot melt adhesive block can be quickly ejected from each groove 2 to achieve rapid demolding and removal of the hot melt adhesive block product.

[0033] Slide grooves 9 are provided on both sides of the inner wall of the housing 3 , and sliders 10 are fixedly connected to both sides of the support plate 51 . The sliders 10 are longitudinally slidably connected in the slide grooves 9 .

[0034] Specifically, by providing the slide groove 9 and the slider 10 , the support plate 51 can be auxiliary supported, making it more stable when moving up and down, which is beneficial for stable demoulding of the hot melt adhesive block and the release paper.

[0035] Both sides of the mold body 1 are fixedly connected with support plates 6, and blowing shells 7 are fixedly installed on the facing surfaces of the support plates 6. Connecting plates 8 are slidably installed on both sides of the shell body 3, and the top of the connecting plate 8 is fixedly connected with a telescopic airbag 81; the top of the telescopic airbag 81 is fixedly connected to the bottom of the support plate 6, and both sides of the bottom of the telescopic airbag 81 are connected with an air intake pipe 82, and the top of the telescopic airbag 81 is connected to the blowing shell 7 through an air supply pipe 83. One-way valves are installed in the air intake pipe 82 and the air supply pipe 83, and one side of the connecting plate 8 is fixedly connected to the support plate 51.

[0036] Specifically, when in use, when the electric push cylinder 5 drives the support plate 51 to move upward, it also drives the connecting plate 8 to move upward and squeezes the telescopic airbag 81, so that the air in the telescopic airbag 81 enters the blowing shell 7 through the air pipe 83 and is continuously blown toward the hot-melt adhesive block in the groove 2 through the air guide cover 11, which can cool the hot-melt adhesive block again during the process of ejecting the hot-melt adhesive block and the release paper. The flowing air takes away the residual heat on the hot-melt adhesive block, thereby reducing the residual heat on the hot-melt adhesive block, reducing the risk of deformation of the hot-melt adhesive block product, and indirectly improving the production quality of the product.

[0037] When the electric push cylinder 5 drives the support plate 51 to move downward and reset, it also drives the connecting plate 8 to move downward and reset and stretch the telescopic airbag 81, so that the outside air enters the telescopic airbag 81 through the air inlet pipe 82, so that it can be used for demolding next time. In addition, the setting of the one-way valve can make the air inlet pipe 82 only take in air, and the air delivery pipe 83 only exhaust air.

[0038] Through openings 12 are formed on both sides of the housing 3 , and the connecting plates 8 are longitudinally slidably connected in the through openings 12 .

[0041] Specifically, by providing the air guide cover 11 , the blowing range of the blowing shell 7 can be expanded, thereby improving the cooling effect on the hot melt adhesive block.

[0042] A filter element 13 is detachably mounted at the air inlet of the air inlet pipe 82 .

[0043] Specifically, by providing the filter element 13 , the air entering the telescopic airbag 81 can be filtered, thereby preventing dust and impurities in the air from entering the telescopic airbag 81 .

[0044] An inspection opening 14 is formed through the surface of the shell 3 , and an inspection cover 15 is detachably mounted on the surface of the shell 3 .

[0045] Specifically, the provision of the inspection port 14 and the inspection cover 15 facilitates the inspection and maintenance of the electric push cylinder 5 in the housing 3 to ensure its effectiveness.

[0046] Working principle: During the use of this hot-melt adhesive block production mold, after the hot-melt adhesive solidifies, the electric push cylinder 5 is started, and the output end of the electric push cylinder 5 drives the support plate 51 and the push rod 52 to move upward, and drives the top plate 4 to slide upward along the inner wall of the groove 2, which can quickly eject the release paper wrapped with the hot-melt adhesive block from each groove 2, so as to realize the rapid demoulding and removal of the hot-melt adhesive block product. At the same time, the release paper will not be torn during the demoulding process, ensuring the integrity of the release paper, which not only improves the demoulding and packaging efficiency of the hot-melt adhesive block, but also reduces the production cost of the enterprise. After the demoulding is completed, the staff can pick up the ejected release paper wrapped with the hot-melt adhesive block and fold it, so as to package the wrapped hot-melt adhesive block as a whole, and finally pack the packaged hot-melt adhesive block into boxes.
