Description
Technical Field
[0001] The utility model belongs to the technical field of injection molding production equipment, and particularly relates to an embossing device for injection molding production. Background Art
[0002] In the production process of injection molded products, since injection molds are used for mass production, they are all put into enterprises for production after complete design, and the products produced are basically finalized. The production cost of the molds themselves is quite high, so it is very difficult to make further changes to the molds. However, some products may have defects, omissions or be trial-produced samples after production. For such products that cannot meet the factory conditions, marks need to be made on the products for subsequent production as reference products. However, this kind of marking cannot be achieved on the mold, and only the formed products can be marked separately after the products are completed. At present, there is no such relevant equipment for use. Generally, marking the products is carried out by means of a signature pen. This kind of marking is very easy to fade over a long time, so that the function of identification is lost. Summary of the Utility Model
[0003] To solve the above technical problems, the utility model provides an embossing device for injection molding production. The cylinder is used to push the rotating seat to drive the pressing rod to press down, so that the die head is pressed against the outer side wall of the product in the die seat. The embossing pattern on the die head presses the pattern text on the product during the heating process, realizing the function of marking.
[0004] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0005] An embossing device for injection molding production includes a support assembly, an embossing assembly and a mold assembly. The support assembly includes a base and support columns, and the support columns are arranged on the side walls of the base; the embossing assembly includes a cylinder, a pressing rod, a pressing head, a support seat, a rotating plate, a rotating seat and a limiting seat. The cylinder is arranged on the support column, and the output end of the cylinder is connected to the pressing head through the pressing rod. The support seat is of a U-shaped structure, and the outer side wall of the support seat is detachably connected to the support column. The rotating plate is rotatably connected in the notch of the support seat, and the cylinder is arranged on the rotating plate. The rotating seat is rotatably connected to the limiting seat through a first rotating shaft, and the limiting seat is detachably connected in the notch of the support seat. The output end of the cylinder is rotatably connected to the rotating seat through a second rotating shaft. The upper end of the pressing rod is rotatably connected to the rotating seat through a third rotating shaft. The outer side wall of the pressing rod is fitted in the through hole on the limiting seat. The first rotating shaft, the second rotating shaft and the third rotating shaft are distributed at triangular positions on the rotating seat; the mold assembly includes a die head and a die seat. The die head is detachably connected to the pressing head, and the die seat is detachably connected to the base. The die head and the die seat correspond to each other.
[0006] For the embossing device used in injection molding production adopting this structure, several locking holes are provided on the base for locking the base on the workbench. The function of the support columns connected to the upper side wall of the base is to provide support force for the embossing assembly. In order to emboss and label the outer side wall of the product, a die head and a die base are required. The die head is provided with the text patterns to be marked, and the die base is provided with a groove for placing the product. The product is embedded in the groove for fixation, and then the die head is pressed onto the product from top to bottom. In order to print the text on the die head onto the product, the die head can be heated. After the heated die head embosses, the product can be locally melted, so that the text and patterns can be printed on the product. The die head and the die base can be replaced according to the actual situation to meet the usage requirements of different products.
[0007] During the embossing process of the die head, a downward displacement is required to achieve the downward pressing effect, and continuous pressure holding is required during the embossing process to achieve a better embossing effect. Therefore, a support seat is provided on the support column for connecting the air cylinder and the limit seat. The upper end of the air cylinder is rotatably connected to the notch of the support seat through a rotating plate. The die head is connected to the through hole on the limit seat through a pressure rod connected by a pressure head. If the output end of the air cylinder is directly connected to the pressure rod to push it downward, then during the pressure holding process, the driving force of the air cylinder needs to be continuously maintained to achieve downward pressing, and more electric energy will be consumed during this process to maintain the downward pressure of the air cylinder. Therefore, a rotating seat is added between the output end of the air cylinder and the pressure rod. The rotating seat is connected to the limit seat through a first rotating shaft, the output end of the air cylinder is connected to the rotating seat through a second rotating shaft, and the upper end of the pressure rod is connected to the rotating seat through a third rotating shaft. Therefore, when the air cylinder starts to push downward, the output end of the air cylinder will push the rotating seat to rotate around the first rotating shaft, and at the same time, the upper end of the air cylinder rotates around the rotating shaft on the rotating plate as the center of rotation. The rotating plate will drive the pressure rod to press downward under the driving force of the air cylinder until the die head on the pressure head is pressed onto the product. Then, after the air cylinder finishes pushing the pressure rod downward, the power supply can be cut off to stop running. Under the torque support of the rotating seat, the pressure rod will always maintain the downward pressing state. When it is necessary to lift the die head, only need to restart the air cylinder to pull upward, and the rotating seat can be twisted to lift the die head.
[0008] Furthermore, assembly holes are provided on the base, and assembly columns are provided at the bottom of the die base. The assembly columns are fitted and connected to the assembly holes; limit holes are also provided on the base, and limit columns are also provided at the bottom of the die base. The limit columns are fitted and connected to the limit holes.
[0009] Compared with the prior art, the advantages of the present utility model are as follows: Through the linkage effect of the air cylinder, the rotating seat and the pressing rod on the limiting seat, when the air cylinder is started, it can push the die head downward, so that the die head is pressed on the product. After the air cylinder finishes pushing the pressing rod downward, the power supply can be cut off to stop running. Under the torque support of the rotating seat, the pressing rod will always maintain the downward pressing state. When it is necessary to lift the die head, only need to restart the air cylinder to pull upward, then the rotating seat can be twisted, so that the die head is lifted. The whole process does not require continuous maintaining the downward pressure of the air cylinder, and the electric energy can be saved. And the downward pressing die head can be heated to press the text pattern on it on the outer side wall of the product to achieve the embossing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation manners of the present utility model will be described below in conjunction with the accompanying drawings:
[0018] As Figures 1-4 shown, an embossing device for injection molding production includes a support assembly 1, an embossing assembly 2 and a mold assembly 3. The support assembly 1 includes a base 11 and support columns 12, and the support columns 12 are arranged on the side walls of the base 11; the embossing assembly 2 includes a cylinder 21, a pressure rod 22, a pressure head 23, a support seat 24, a rotating plate 25, a rotating seat 26 and a limiting seat 27. The cylinder 21 is arranged on the support column 12, and the output end of the cylinder 21 is connected to the pressure head 23 through the pressure rod 22. The support seat 24 has a U-shaped structure, and the outer side wall of the support seat 24 is detachably connected to the support column 12. The rotating plate 25 is rotatably connected in the notch of the support seat 24, and the cylinder 21 is arranged on the rotating plate 25. The rotating seat 26 is rotatably connected to the limiting seat 27 through a first rotating shaft 261, and the limiting seat 27 is detachably connected in the notch of the support seat 24. The output end of the cylinder 21 is rotatably connected to the rotating seat 26 through a second rotating shaft 262. The upper end of the pressure rod 22 is rotatably connected to the rotating seat 26 through a third rotating shaft 263. The outer side wall of the pressure rod 22 is fitted in the through hole 271 on the limiting seat 27. The first rotating shaft 261, the second rotating shaft 262 and the third rotating shaft 263 are distributed at triangular positions on the rotating seat 26; the mold assembly 3 includes a mold head 31 and a mold base 32. The mold head 31 is detachably connected to the pressure head 23, and the mold base 32 is detachably connected to the base 11. The mold head 31 and the mold base 32 correspond to each other.
[0019] Furthermore, an assembly hole 111 is provided on the base 11, and an assembly post 321 is provided at the bottom of the mold base 32. The assembly post 321 is fitted and connected in the assembly hole 111; a limiting hole 112 is also provided on the base 11, and a limiting post 322 is also provided at the bottom of the mold base 32. The limiting post 322 is fitted and connected in the limiting hole 112.
[0020] The working mode of the present utility model is described as follows:
[0021] The embossing device for injection molding production adopting this structure is provided with a number of locking holes on the base 11 for locking the base 11 on the workbench. The supporting column 12 connected to the upper side wall of the base 11 serves to provide a supporting force for the embossing assembly 2. In order to emboss and label the outer side wall of the product, the die head 31 and the die base 32 are required. The die head 31 is provided with the text patterns to be marked, and the die base 32 is provided with a groove for placing the product. The product is embedded in the groove for fixation, and then the die head 31 is pressed onto the product from top to bottom. In order to enable the text on the die head 31 to be printed on the product, the die head 31 can be heated. After the heated die head 31 is embossed, the product can be locally melted, so that the text and patterns can be printed on the product. The die head 31 and the die base 32 can be replaced according to the actual situation to meet the usage requirements of different products. The assembly holes 111 and the limiting holes 112 provided on the base 11 are respectively matched with the assembly posts 321 and the limiting posts 322 on the bottom of the die base 32, so that the die base 32 can be disassembled and replaced to meet the requirements of different products.
[0022] During the embossing process of the die head 31, a downward displacement is required to achieve the downward pressing effect, and continuous pressure holding is required during the embossing process to achieve a better embossing effect. Therefore, a support seat 24 is provided on the support column 12 for connecting the air cylinder 21 and the limiting seat 27. The upper end of the air cylinder 21 is rotatably connected to the notch of the support seat 24 through a rotating plate 25. The pressure rod 22 connected by the die head 23 is cooperatively connected to the through hole 271 on the limiting seat 27. If the output end of the air cylinder 21 is directly connected to the pressure rod 22 to push and press down, then during the pressure holding process, the driving force of the air cylinder 21 needs to be continuously maintained to achieve downward pressing. More electric energy will be consumed during this process to maintain the downward pressure of the air cylinder 21. Therefore, a rotating seat 26 is added between the output end of the air cylinder 21 and the pressure rod 22. The rotating seat 26 is connected to the limiting seat 27 through a first rotating shaft 261. The output end of the air cylinder 21 is connected to the rotating seat 26 through a second rotating shaft 262. The upper end of the pressure rod 22 is connected to the rotating seat 26 through a third rotating shaft 263. Therefore, when the air cylinder 21 is started to push and press down, the output end of the air cylinder 21 will push the rotating seat 26 to rotate around the first rotating shaft 261. At the same time, the upper end of the air cylinder 21 rotates around the rotating shaft on the rotating plate 25 as the rotation center, and the rotating plate 25 will drive the pressure rod 22 to press down under the driving force of the air cylinder 21 until the die head 31 on the pressure head 23 is pressed onto the product. Then, after the air cylinder 21 completes pushing the pressure rod 22 to press down, the power supply can be cut off and the operation can be stopped. Under the torque support of the rotating seat 26, the pressure rod 22 will always maintain the downward pressing state. When it is necessary to lift the die head 31, only need to restart the air cylinder 21 to pull up, and the rotating seat 26 can be twisted to lift the die head 31.
[0023] The beneficial effects of the present utility model are as follows: Through the linkage effect of the air cylinder 21, the rotating seat 26 and the pressing rod 22 on the limiting seat 27, when the air cylinder 21 is started, it can push the die head 31 downward, so that the die head 31 is pressed against the product. After the air cylinder 21 finishes pushing the pressing rod 22 downward, the power supply can be cut off to stop the operation. Under the torque support of the rotating seat 26, the pressing rod 22 will always maintain the downward pressing state. When it is necessary to lift the die head 31, only need to restart the air cylinder 21 to pull upward, then the rotating seat 26 can be twisted, so that the die head 31 is lifted. The whole process does not need to continuously maintain the downward pressure of the air cylinder 21, and the electric energy can be saved. The downward pressing die head 31 can be heated to press the text pattern on it onto the outer side wall of the product to achieve the embossing effect.
[0024] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
