Description

Technical Field

[0001] This utility model relates to the field of automotive parts mold technology, specifically to a mold for processing automotive parts that is easy to demold. Background Technology

[0002] Automotive parts molds are essential tools for manufacturing automotive components. Through specific forming processes, they shape materials such as metal or plastic into the desired forms of automotive parts. They are primarily used to process metal automotive components, such as body panels and engine mounts. Pressure is applied to metal sheets using equipment like punch presses, causing plastic deformation within the mold to obtain the desired shape and size. However, existing automotive parts molds have some shortcomings, such as:

[0003] Application No.: CN202211139992.7 describes a high-precision injection mold for automotive parts processing that facilitates demolding. This equipment provides assistance for demolding, solving the problem that traditional automotive parts processing molds require excessive driving force for demolding, resulting in slow demolding speed. However, during the demolding process, the mold may disassemble from the workpiece surface, causing damage under the pull force. This may also lead to the mold and workpiece sticking together, making demolding difficult.

[0004] Therefore, we propose a mold for processing automotive parts that facilitates demolding, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a mold for processing automotive parts that is easy to demold, in order to solve the problem mentioned in the background art that the molds on the market are not easy to demold when they are bonded to the workpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mold for processing automotive parts that is easy to demold, comprising a device body and a mold groove installed on the top of the device body, a top plate provided on the top of the device body, a cylinder provided inside the top plate, and an upper mold provided at the bottom of the cylinder, wherein the top of the upper mold is provided with an injection hole;

[0007] The main body of the device is equipped with a drive mechanism, and the right end of the drive mechanism is connected to the ejection mechanism and the push-out mechanism. The ejection mechanism includes a drive shaft, a first bevel gear meshing on the outside of the drive shaft, a second bevel gear meshing on the top of the first bevel gear, and a first reciprocating threaded shaft connected to the top of the second bevel gear. A first threaded sleeve is provided on the outside of the first reciprocating threaded shaft, and a lower mold is connected to the top of the first threaded sleeve. The lower mold is located inside the mold groove.

[0008] When the upper mold, mold groove, and lower mold are injection molded to form a workpiece, the first reciprocating threaded shaft in the ejection mechanism will drive the first threaded sleeve to rise and fall, thereby causing the first threaded sleeve to drive the lower mold to rise, so that the workpiece separates from the mold groove surface and rises. When the top of the lower mold rises to the same level as the mold groove, the bottom of the workpiece may stick to the lower mold. The ejection mechanism can apply pressure to the right side of the workpiece to make the workpiece separate from the lower mold. Thus, during the demolding process, the workpiece is separated by the action of the lower pressure and the right side pressure, avoiding the problem of difficulty in demolding when the lower mold and the workpiece stick together.

[0009] As a preferred technical solution of this utility model, the top of the main body of the device is provided with a limiting shaft, and the top of the limiting shaft is slidably connected to the upper mold, and the lower mold is slidably connected to the inside of the mold groove. The inside of the mold groove is provided with a connecting damper, and the top of the connecting damper is connected to the lower mold.

[0010] The above technical solution can prevent the upper mold from shifting when it fits into the mold groove, thereby increasing the accuracy of the equipment when assembling molds.

[0011] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor. The left end of the drive motor is provided with a first sprocket, a chain is engaged on the outside of the first sprocket, and a second sprocket is engaged on the top of the chain. Both the left ends of the first sprocket and the second sprocket are provided with ratchet groups.

[0012] The above technical solution enables the drive mechanism to be more stable when connected with the ejector and push-out mechanisms, thereby increasing the stability of the drive mechanism when driving the ejector or push-out mechanisms.

[0013] As a preferred technical solution of this utility model, the second sprocket is connected to the inside of the device body through a bearing seat, and the ratchet group includes a first ratchet, and the left end of the first ratchet is engaged with the second ratchet. The left end of the second ratchet is connected to a spring shaft, and the ratchet group at the left end of the first sprocket and the ratchet group at the left end of the second sprocket face opposite directions.

[0014] The above technical solution enables the drive mechanism to be more stable when controlling the ejection or push-out mechanism, thereby increasing the controllability of the equipment during operation.

[0015] As a preferred technical solution of this utility model, the first sprocket is connected to the drive shaft through a ratchet assembly, and the left end of the second sprocket is connected to the ejection mechanism through the ratchet assembly. The ejection mechanism includes a second reciprocating threaded shaft, a second threaded sleeve is provided on the outside of the second reciprocating threaded shaft, and a push plate is connected to the left end of the second threaded sleeve. When the ejection mechanism ejects the workpiece out of the mold groove, the push plate will push the workpiece to the left end of the device body under the drive of the second threaded sleeve.

[0016] The above technical solution enables the workpiece to be separated from the lower mold by applying pressure to the right side of the workpiece through the push plate when the bottom of the lower mold is bonded to the workpiece, thereby increasing the stability of the equipment during demolding.

[0017] As a preferred technical solution of this utility model, the bottom of the device body is provided with a bearing seat, and the device body is connected to the second bevel gear through the bearing seat, and the drive shaft is rotatably connected to the inside of the device body.

[0018] The above technical solution enables the second bevel gear and the first reciprocating threaded shaft to be more stable when they are fixed and limited, thereby increasing the stability of the ejection mechanism during operation.

[0019] As a preferred technical solution of this utility model, the top of the device body is slidably connected to the second threaded sleeve, and the top of the device body is in contact with and slides against the push plate.

[0020] The above technical solution enables the top of the device body to limit the second threaded sleeve in the ejection mechanism, thereby increasing the stability of the ejection mechanism during operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: when the upper mold, mold groove and lower mold are injection molded to form a workpiece, the first reciprocating threaded shaft in the ejection mechanism will drive the first threaded sleeve to rise and fall, thereby causing the first threaded sleeve to drive the lower mold to rise, so that the workpiece separates from the mold groove surface and rises. When the top of the lower mold rises to the same level as the mold groove, the bottom of the workpiece sticks to the lower mold. The ejection mechanism can apply pressure to the right side of the workpiece to make the workpiece separate from the lower mold. Thus, during the demolding process, the workpiece is separated by the action of the lower pressure and the right side pressure, avoiding the problem of difficulty in demolding when the lower mold sticks to the workpiece.

[0022] Furthermore, by setting the limiting shaft, the upper mold can avoid the problem of displacement when it fits into the mold groove, thereby increasing the accuracy of the equipment when assembling molds.

[0023] Furthermore, the ratchet assembly makes the drive mechanism more stable when controlling the ejection or push-out mechanism, thereby increasing the controllability of the device during operation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] To address the problem of difficulty in demolding when the lower mold 7 is bonded to the workpiece in the prior art, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a mold for processing automotive parts that is easy to demold, including a device body 1 and a mold groove 2 installed on the top of the device body 1. The top of the device body 1 is provided with a top plate 3, and a cylinder 4 is provided inside the top plate 3. The bottom of the cylinder 4 is provided with an upper mold 5, and the top of the upper mold 5 is provided with an injection hole.

[0032] The main body 1 of the device is equipped with a drive mechanism, and the right end of the drive mechanism is connected to the ejection mechanism and the push-out mechanism. The ejection mechanism includes a drive shaft 15, a first bevel gear 16 meshing on the outside of the drive shaft 15, a second bevel gear 17 meshing on the top of the first bevel gear 16, and a first reciprocating threaded shaft 18 connected to the top of the second bevel gear 17. A first threaded sleeve 19 is provided on the outside of the first reciprocating threaded shaft 18, and a lower mold 7 is connected to the top of the first threaded sleeve 19. The lower mold 7 is located inside the mold groove 2.

[0033] The device body 1 is provided with a limiting shaft 6 at the top, and the top of the limiting shaft 6 is slidably connected to the upper mold 5, and the lower mold 7 is slidably connected to the inside of the mold groove 2. The mold groove 2 is provided with a connecting damper 20, and the top of the connecting damper 20 is connected to the lower mold 7.

[0034] The main body 1 of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 8. The left end of the drive motor 8 is provided with a first sprocket 9, a chain 10 is engaged on the outside of the first sprocket 9, and a second sprocket 11 is engaged on the top of the chain 10. Both the left ends of the first sprocket 9 and the second sprocket 11 are provided with ratchet groups.

[0035] The second sprocket 11 is connected to the inside of the device body 1 through the bearing seat, and the ratchet group includes the first ratchet 12, and the left end of the first ratchet 12 is engaged with the second ratchet 13. The left end of the second ratchet 13 is connected to the spring shaft 14, and the ratchet group at the left end of the first sprocket 9 and the ratchet group at the left end of the second sprocket 11 face opposite directions.

[0036] The first sprocket 9 is connected to the drive shaft 15 via a ratchet assembly, and the left end of the second sprocket 11 is connected to the ejection mechanism via a ratchet assembly. The ejection mechanism includes a second reciprocating threaded shaft 21, and a second threaded sleeve 22 is provided on the outside of the second reciprocating threaded shaft 21. A push plate 23 is connected to the left end of the second threaded sleeve 22. When the ejection mechanism ejects the workpiece out of the mold groove 2, the push plate 23 will push the workpiece to the left end of the device body 1 under the drive of the second threaded sleeve 22.

[0037] The bottom of the device body 1 is provided with a bearing seat, and the device body 1 is connected to the second bevel gear 17 through the bearing seat, and the drive shaft 15 is rotatably connected to the inside of the device body 1; the top of the device body 1 is slidably connected to the second threaded sleeve 22, and the top of the device body 1 is in contact with and slides against the push plate 23.

[0038] Working principle: When using this easy-to-demold mold for processing automotive parts, first connect the equipment to the power supply and the grid. Then, the cylinder 4 drives the upper mold 5 to fit inside the mold groove 2, so that the mold groove 2, the upper mold 5 and the lower mold 7 form a mold cavity. Then, injection molding is performed through the injection hole set on the top of the upper mold 5. When the injection is completed, the upper mold 5 rises under the drive of the cylinder 4. At the same time, the drive mechanism drives the ejection mechanism to run, so that the drive shaft 15 drives the two sets of first bevel gears 16 to rotate, so that the first bevel gears 16 drive the second bevel gear 17 and the first reciprocating threaded shaft 18 to rotate, so that the first threaded sleeve 19 drives the lower mold 7 to rise, so that the outer side of the workpiece is separated from the mold groove 2. When the top of the lower mold 7 fits into the mold groove, the drive mechanism drives the ejection mechanism to run. The ejection mechanism applies pressure to the right side of the workpiece, so that the top of the lower mold 7 is separated from the workpiece, and then the workpiece is pushed to the designated position for collection.

[0039] When the drive mechanism is running, the drive motor 8 will drive the first sprocket 9 to rotate in the forward direction, thereby causing the ratchet group at the left end of the first sprocket 9 to engage, that is, the first ratchet 12 and the second ratchet 13 to engage. The second ratchet 13 will then drive the drive shaft 15 to rotate through the spring shaft 14. Since the ratchet group at the left end of the first sprocket 9 and the ratchet group at the left end of the second sprocket 11 face opposite directions, the ratchet group at the left end of the second sprocket 11 will disengage, that is, the first ratchet 12 and the second ratchet 13 will disengage. The second ratchet 13 will then retract under the drive of the spring shaft 14.

[0040] When the drive motor 8 rotates in the reverse direction, the ratchet assembly at the left end of the second sprocket 11 will engage, causing the second sprocket 11 to drive the ejection mechanism to run, causing the second reciprocating threaded shaft 21 to drive the second threaded sleeve 22 to move, which in turn causes the second threaded sleeve 22 to drive the push plate 23 to move, thus causing the push plate 23 to fit against and push the right side of the workpiece. After the workpiece is pushed to the designated position by the push plate 23, the push plate 23 will be reset under the drive of the second threaded sleeve 22, thus waiting to be pushed after the next injection molding is completed.

[0041] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
