Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine component molding, in particular to a pick-up and delivery device used for press-fitting of injection molding machine components. Background Art

[0002] During the process of the hydraulic press pressing the injection molding machine components, workers are required to place the workpiece on the pressing table of the hydraulic press, and after the workpiece is pressed into shape, the workers take the workpiece out. The workers work in a small range on the hydraulic press, which is inconvenient to operate and poses a safety hazard.

[0003] A Chinese patent with application number 202020108119.1 discloses a press demolding and picking device, including a mold cavity, a mold bushing is arranged in the mold cavity, a pressed material is placed in the mold bushing, and a press head is also arranged above the mold bushing; a picking cavity is arranged below the mold cavity, a demolding sliding block is arranged in the picking cavity, and the width of the demolding sliding block is greater than the storage space for the pressed material; a telescopic cylinder is arranged outside the picking cavity, and the telescopic cylinder is connected to the demolding sliding block.

[0004] In this solution, the demoulding slide block is located below the material storage space as a support block. After the material is pressed, the telescopic cylinder drives the demoulding slide block to retract, and the pressing head presses down again to press the formed material out of the mold and fall into the removal cavity. Then the pressing head retreats, and the telescopic cylinder drives the demoulding slide block to extend out from under the material storage space. At the same time, the moving demoulding slide block pushes the pressed material out of the working part of the press for easy removal.

[0005] However, the above solution only solves the problem that workers can take parts outside the press to reduce risks; when loading parts, workers are still required to place workpieces or materials on the pressing table inside the press, and risks still exist. Utility Model Content

[0006] The utility model aims at the disadvantage of potential safety hazards when workers take and place workpieces on a hydraulic press in the prior art, and provides a taking and delivering device for press-fitting of injection molding machine components.

[0007] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0008] A pick-up and delivery device for press-fitting of injection molding machine components comprises a base, a support block protruding from the base, and a press-fitting platform mounted on the support block on which a workpiece can be placed, and a transverse driving structure is arranged between the base and the press-fitting platform to drive the press-fitting platform to reciprocate outside the hydraulic press and below the hydraulic press pressure head.

[0009] By adopting the above scheme, the lateral driving structure drives the pressing platform to move from under the pressure head of the hydraulic press to outside the hydraulic press. The worker places the workpiece to be pressed on the top of the pressing platform. The lateral driving structure drives the pressing platform to retract into the hydraulic press. The pressure head of the hydraulic press descends to press the workpiece. The support block provides support force to the pressing platform when the pressure head presses the workpiece to avoid excessive pressure when the pressure head of the hydraulic press presses down and damage to the lateral driving structure. After pressing is completed, repeat the above steps to transfer the pressed workpiece out of the hydraulic press and take the workpiece to be pressed back into the hydraulic press. Workers take and place the workpieces outside the hydraulic press, which reduces risks. The large external space of the hydraulic press makes taking and placing more convenient.

[0010] Preferably, the lateral driving structure includes a guide structure for controlling the moving direction of the press-fitting platform and a driving cylinder fixed on the base for driving the press-fitting platform to move.

[0011] By adopting the above scheme, the piston rod of the driving cylinder extends to drive the pressing platform to partially move out of the hydraulic press. Conversely, the piston rod of the driving cylinder retracts to drive the pressing platform to be located under the pressure head of the hydraulic press, and the guide structure controls the moving direction of the pressing platform to ensure horizontal and linear movement of the pressing platform.

[0012] Preferably, the guide structure includes a guide rail arranged on the side wall of the support block along the moving direction of the press-fitting platform and a sliding block connected to the press-fitting platform and embedded and slidably matched with the guide rail.

[0013] With the above solution, the guide rail is fixedly arranged on the side wall of the support block along the moving direction of the press-fitting platform, and the slider is embedded and slides in the guide rail to ensure horizontal linear movement of the slider, thereby ensuring the sliding direction of the press-fitting platform.

[0014] Preferably, the slider is connected to the press-fitting platform via a lifting structure, which enables the press-fitting platform and the slider to translate synchronously while driving the press-fitting platform to move vertically relative to the slider. The piston rod end of the driving cylinder is connected to the press-fitting platform via a follow-up adjustment structure. When the press-fitting platform is lifted or lowered, the press-fitting platform and the slider can be driven by the driving cylinder to translate synchronously.

[0015] With the above solution, the slider is connected to the press-fitting platform through a lifting structure. When the driving cylinder drives the press-fitting platform to move, the lifting structure and the slider both move synchronously with the press-fitting platform. The lifting structure can also make the press-fitting platform rise and leave the support block, reducing the friction when the press-fitting platform moves; or drive the press-fitting platform to descend and abut against the support block. The lifting structure moves horizontally synchronously with the press-fitting platform and can control the lifting and lowering of the press-fitting platform. Therefore, a follow-up adjustment structure needs to be set between the piston rod of the driving cylinder and the press-fitting platform to ensure that the press-fitting platform can move horizontally and reciprocatingly under the drive of the driving cylinder, and can also move relative to the driving cylinder in the vertical direction to ensure the smooth lifting and lowering of the press-fitting platform.

[0016] Preferably, the lifting structure comprises a lifting cylinder, a cylinder body of the lifting cylinder is fixed on the slider, a piston rod of the lifting cylinder is vertically upward and an end portion is fixedly connected to the press-fitting platform.

[0017] By adopting the above scheme, the press-fitting platform is controlled to rise when the piston rod of the jacking cylinder is extended, and the press-fitting platform is controlled to fall when the piston rod of the jacking cylinder is retracted. The jacking cylinder is fixedly connected to the slider and the press-fitting platform respectively, so that the press-fitting platform can drive the jacking cylinder and the slider to move horizontally when it moves horizontally, and the guiding cooperation of the slider and the guide rail ensures the guided movement of the press-fitting platform.

[0018] Preferably, two groups of support blocks, guide rails and sliders are provided and symmetrically distributed on both sides of the driving cylinder. The driving cylinder is located in the middle of the press platform, and at least one lifting cylinder is arranged at intervals along the moving direction of the press platform.

[0019] With the above solution, only one lifting cylinder is needed to control the lifting and lowering of the press-fitting platform. If multiple lifting cylinders are used, the force on a single lifting cylinder can be dispersed, which protects the lifting cylinder and makes the lifting and lowering of the press-fitting platform more stable. The support blocks, guide rails and sliders are symmetrically distributed on both sides of the driving cylinder, which provides more stable support and guidance for the press-fitting platform.

[0020] Preferably, the follow-up adjustment structure includes a connecting adjustment plate fixed vertically downward on the side of the pressing platform away from the piston rod of the driving cylinder, a screw fixed to the end of the piston rod of the driving cylinder and the two are coaxially arranged, and a waist-shaped hole vertically arranged on the connecting adjustment plate through which the screw can pass and allows the connecting adjustment plate to be vertically lifted and lowered relative to the screw. Limit blocks and limit nuts are respectively arranged on both sides of the connecting adjustment plate on the screw to limit the relative horizontal movement of the two.

[0021] With the above solution, one end of the screw rod passes through the oval hole, and the screw rod is provided with a limit block and a limit nut on both sides of the fixed plate to ensure that when the piston rod of the driving cylinder is extended or retracted, the connecting adjustment plate is driven to move horizontally together. The screw rod can be vertically raised or lowered in the oval hole, so that the press-fitting platform can be raised or lowered relative to the pneumatic cylinder.

[0022] The utility model has significant technical effects due to the adoption of the above technical scheme: the lifting cylinder controls the pressing platform to rise and separate from the supporting block, the driving cylinder drives the pressing platform to move from under the pressure head of the hydraulic press to outside the hydraulic press, the worker places the workpiece to be pressed above the pressing platform, the driving cylinder drives the pressing platform to retract into the hydraulic press, the lifting cylinder drives the pressing platform to descend to abut against the supporting block, the pressure head of the hydraulic press descends to press the workpiece, and after the pressing is completed, the above steps are repeated to convey the pressed workpiece out of the hydraulic press and take the workpiece to be pressed back into the hydraulic press. The workers take and place the workpieces outside the hydraulic press, which reduces the risk and the hydraulic press has a large external space, making it more convenient to take and place.

A support block 2 is convexly provided on the upper end surface of the base 1 near the pressure head, and a press platform 3 is mounted on the support block 2. The press platform 3 is used to place the workpiece to be pressed. The press platform 3 can reciprocate outside the hydraulic press and below the pressure head of the hydraulic press, and the translation of the press platform 3 is controlled by the lateral driving structure.

[0035] The transverse driving structure is arranged between the base 1 and the press-fitting platform 3, and includes a driving cylinder 4 fixed on the base 1, and the piston rod of the driving cylinder 4 is connected to the press-fitting platform 3. A guiding structure for controlling the horizontal linear movement of the press-fitting platform 3 is arranged between the support block 2 and the press-fitting platform 3, and includes a guide rail 5 arranged on the support block 2 and a slider 6 connected to the press-fitting platform 3. The guide rail 5 is fixedly arranged linearly on the side wall of the support block 2 along the moving direction of the press-fitting platform 3, and the slider 6 is embedded and slid in the guide rail 5 to ensure the horizontal linear movement of the slider 6, thereby ensuring the sliding direction of the press-fitting platform 3. The cylinder body of the driving cylinder 4 is fixed on the base 1 and located in the middle of the press-fitting platform 3. The support block 2, the guide rail 5 and the slider 6 are arranged in two groups and symmetrically distributed on both sides of the driving cylinder 4, and the two groups of guide rails 5 and sliders 6 are respectively arranged on the opposite sides of the two support blocks 2 to ensure the force balance on the press-fitting platform 3.

[0036] The slider 6 is connected to the press-fitting platform 3 through a lifting structure, which can make the press-fitting platform 3 and the slider 6 move synchronously, and can also drive the press-fitting platform 3 to move vertically relative to the slider 6. The piston rod end of the driving cylinder 4 is connected to the press-fitting platform 3 through a follow-up adjustment structure, ensuring that the press-fitting platform 3 can move horizontally and reciprocatingly under the drive of the driving cylinder 4, and can also move relative to the driving cylinder 4 in the vertical direction to ensure the smooth lifting and lowering of the press-fitting platform 3.

[0037] The lifting structure includes a lifting cylinder 7, the cylinder body of the lifting cylinder 7 is fixed on the slider 6, and the piston rod of the lifting cylinder 7 is vertically upward and the end is fixedly connected to the press-fitting platform 3. When the piston rod of the lifting cylinder 7 is extended, the press-fitting platform 3 is controlled to rise, and when the piston rod of the lifting cylinder 7 is retracted, the press-fitting platform 3 is controlled to descend. Two lifting cylinders 7 are arranged between each slider 6 and the press-fitting platform 3, and the two lifting cylinders 7 are arranged at intervals along the moving direction of the press-fitting platform 3.

[0038] The follow-up adjustment structure includes a connection adjustment plate 8 fixedly arranged on the press-fitting platform 3.

The short side of the "L-shaped" connection adjustment plate 8 is fixed to the side of the press-fitting platform 3 away from the piston rod of the driving cylinder 4, and the long side of the "L-shaped" connection adjustment plate 8 is vertically connected to the piston rod of the driving cylinder 4. A screw rod 9 is coaxially fixed to the end of the piston rod of the driving cylinder 4. A waist-shaped hole 10 is vertically arranged on the connection adjustment plate 8 for the screw rod 9 to pass through and allows the connection adjustment plate 8 to be vertically lifted and lowered relative to the screw rod 9. A limit block 11 and a limit nut 12 are respectively arranged on both sides of the screw rod 9 to limit the relative horizontal movement of the screw rod 9 and the connection adjustment plate 8. The limit block 12 is fixed on the screw rod 9 and is located between the cylinder body of the driving cylinder 4 and the connection adjustment plate 8. The limit nut 12 is threadedly matched with the screw rod 9 and can cooperate with the limit block 11 to limit the connection adjustment plate 8.

[0039] During assembly, first unscrew the limit nut 12. After the screw 9 passes through the oval hole 10, the limit block 11 abuts against the side of the cylinder body of the connecting adjustment plate 8 close to the driving cylinder 4, and then install the limit nut 12 that was previously unscrewed on the screw 9 and tighten it so that the limit block 11 and the limit nut 12 are located on both sides of the connecting adjustment plate 8.

[0040] During operation, the lifting cylinder 7 controls the pressing platform 3 to rise and separate from the support block 2, and the driving cylinder 4 drives the pressing platform 3 to move from under the pressure head of the hydraulic press to the outside of the hydraulic press. The worker places the workpiece to be pressed on the pressing platform 3, and the driving cylinder 4 drives the pressing platform 3 to retract into the hydraulic press. The lifting cylinder 7 drives the pressing platform 3 down to abut against the support block 2, and the pressure head of the hydraulic press descends to press the workpiece. After pressing is completed, repeat the above steps to transport the pressed workpiece out of the hydraulic press and take the workpiece to be pressed back into the hydraulic press.
