[0030] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Specific embodiments, combined with Figures 1 to 10 As shown, the technical solution of this utility model is further explained. A molding machine feeding device includes a frame (not shown in the figure), a workbench 10 for feeding mold 1 is installed on one side of the frame, a supporting mechanism 20 for supporting mold 1 is provided on the frame, and a driving mechanism 30 for driving the supporting mechanism 20 to move. A safety protection mechanism 40 for ensuring the safe movement of the supporting mechanism 20 is provided on the side near the workbench 10.

[0032] In this embodiment, since there is a certain distance between the workbench 10 for placing the mold 1 and the feeding position, the safety protection mechanism 40 can ensure that the supporting mechanism 20 holding the mold 1 will only move to the feeding position under safe conditions, thereby effectively avoiding safety accidents such as pinching or collision injuries to operators during equipment operation.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the safety protection mechanism 40 includes a safety cover 41, a safety lock 42 disposed on the safety cover 41, and a safety sensor 43 for detecting whether there is a mold on the placing mechanism 20. The safety lock 42 and the safety sensor 43 form an interlocking mechanism, so that the placing mechanism 20 can only move to the feeding position under safe conditions.

[0034] Specifically, the safety conditions are that the safety door lock 42 is locked and the safety sensor 43 detects that the mold 1 is placed on the placing mechanism 20, and only then will the driving mechanism 30 drive the placing mechanism 20 to move forward to the feeding position.

[0035] In this embodiment, the safety guard provides a physical barrier to prevent operators from accidentally touching it during the operation of the holding mechanism, thus preventing accidental injury to the operators. Secondly, the interlocking mechanism formed by the safety door lock and the safety sensor ensures that the holding mechanism containing the mold will only move to the feeding position under safe conditions, effectively avoiding safety accidents such as pinching or collision injuries to operators during material transportation.

[0036] In a preferred embodiment, the safety cover 41 includes a first protective cover 411, which is fixedly mounted on the frame. A second protective cover 412 for covering the workbench 10 is provided on the side of the first protective cover 411 near the workbench 10. A rotating connection assembly 413 is provided between the first protective cover 411 and the second protective cover 412, so that the second protective cover 412 can rotate relative to the first protective cover 411.

[0037] Alternatively, the rotating connection assembly 413 includes a first fixing member 4131 fixedly installed on the first protective cover 411, and a second fixing member 4132 fixedly installed on the second protective cover 412, with a rotating shaft 4133 provided between the first fixing member 4131 and the second fixing member 4132.

[0038] In this embodiment, the first protective cover and the second protective cover form a fully enclosed structure, which effectively prevents operators from accidentally touching the receiving mechanism, thereby causing safety accidents such as pinching or collision injuries to the operators; secondly, the second protective cover rotates relative to the first protective cover, so that the operator can flexibly open the protective cover to feed materials when placing the mold, and quickly close it after the operation is completed, ensuring that the safety protection during the operation of the equipment is not interrupted.

[0039] In a preferred embodiment, the security door lock 42 includes a first door lock 421 disposed on the side of the first protective cover 411, and a second door lock 422 disposed on the side of the second protective cover 412 and locked in cooperation with the first door lock 421.

[0040] Alternatively, the security door lock 42 may include, but is not limited to, an electromagnetic door lock or a mechanical door lock. Preferably, the security door lock 42 in this embodiment is an electromagnetic door lock, that is, the first door lock 421 and the second door lock 422 achieve the locking and unlocking of the first protective cover 411 and the second protective cover 412 by magnetic field force.

[0041] In this embodiment, the safety door lock design ensures that the safety cover will not be accidentally opened during equipment operation, preventing operators from accidentally touching moving parts and avoiding safety accidents such as pinching or collisions. Secondly, the safety door lock in this embodiment is an electromagnetic door lock, which, compared to mechanical door locks, does not have a complex mechanical structure, reducing the risk of failure due to wear and tear of mechanical parts and improving the reliability of the equipment. In addition, the locking force of the electromagnetic door lock is relatively stable, ensuring that the safety cover remains closed during equipment operation and avoiding safety hazards caused by the safety cover loosening.

[0042] In a preferred embodiment, the safety sensor 43 is disposed on the workbench 10.

[0043] Alternatively, the safety sensor 43 may include, but is not limited to, a photoelectric sensor, a safety light curtain, or a proximity switch. Preferably, in this embodiment, the safety sensor 43 is a photoelectric sensor.

[0044] In this embodiment, the safety sensor can monitor in real time whether there is a mold on the placing mechanism, ensuring that a mold is placed on the placing mechanism and that it is under safe conditions before driving the placing mechanism to move forward to the material feeding position, thus avoiding safety accidents caused by empty running or misoperation.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the workbench 10 includes a work panel 11, with support columns 12 provided at each of the four corners of the work panel 11. The work panel 11 has an opening 111 for placing the mold 1, the width of which matches the width of the mold holding platform 21. The safety sensor 43 is installed on the work panel 111.

[0046] The height of the support column 11 is not lower than the height of the supporting mechanism 20. Preferably, the height of the support column 11 is the same as the height of the supporting mechanism 20.

[0047] In this embodiment, the opening design on the work panel ensures that the mold can be conveniently and accurately placed onto the receiving mechanism, reducing manual intervention and operational difficulty. Secondly, the height design of the support column ensures that the work panel and the receiving mechanism are at the same height, facilitating the transfer of the mold between the workbench and the receiving mechanism by the operator, and improving the convenience of operation.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the supporting mechanism 20 includes a mold supporting platform 21 and a lifting assembly 22 for controlling the lifting and lowering of the mold supporting platform 21. A sealing ring (not shown in the figure) is provided at the mold supporting platform 21 where the mold 1 is supported.

[0049] Alternatively, the lifting assembly 22 may include, but is not limited to, a lifting cylinder or a lifting hydraulic cylinder. Preferably, in this embodiment, the lifting assembly 22 is a lifting cylinder.

[0050] In this embodiment, the cooperation between the mold placement platform and the lifting component ensures that the mold is accurately positioned during the feeding process, ensuring that the mold is placed in the same position each time, avoiding mold damage or production delays caused by positional deviations; secondly, when different batches of mold models need to be fed, the precise control of the lifting component can ensure that each batch of molds can be placed in its corresponding position, improving the repeatability and consistency of the production process.

[0051] In addition, the sealing rings on the mold support platform can effectively prevent material leakage or external impurities from entering the molding cavity, ensuring the sealing of the molding process, thereby improving the product yield and quality stability.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the driving mechanism 30 includes a linear guide rail 31 and a linear motor 32, a slider 33 is mounted on the linear guide rail 31, and the supporting mechanism 20 is mounted on the slider 33;

[0053] The linear motor 32 controls the slider 33 to move along the linear guide rail 31, so that the supporting mechanism 20 moves synchronously with the slider 33.

[0054] In this embodiment, a linear motor is used as the drive source. The high-precision control of the linear motor ensures that the feeding mechanism can move accurately to the feeding position every time, avoiding production failures caused by movement errors. Secondly, the low friction characteristics of the linear guide and the sliding mechanism can ensure that the feeding mechanism remains stable during movement, reducing equipment vibration or impact and extending the service life of the equipment.

[0055] Furthermore, as a preferred embodiment of this solution and not a limitation, a cable chain 2 for protecting the motor control lines and air hoses is also installed on the frame.

[0056] In this embodiment, the cable chain can effectively protect the motor control lines and air hoses, reduce wear on the cables and air hoses caused by friction, bending and stretching during equipment operation, and extend their service life. In addition, the cable chain can prevent the cables and air hoses from being damaged by external forces, ensuring the normal operation of the equipment and improving the reliability of the equipment.

[0057] The working principle of this utility model is as follows:

[0058] The molding machine feeding device proposed in this utility model can effectively prevent safety accidents such as pinching or collision injuries to operators during the process of the supporting mechanism 20 holding the mold 1 moving forward to the feeding position. Its specific principle is as follows:

[0059] First, the operator opens the second protective cover 412 and places the mold 1 onto the mold support platform 21 through the opening 111 of the workbench 10. After placement, the photoelectric sensor 43 can detect that the mold 1 is placed on the support mechanism 20. However, since the second protective cover 412 is not closed, that is, the safety lock 42 is in the unlocked state, the safety condition has not been met. At this time, the drive mechanism 30 will not drive the support mechanism 20 with the mold 1 to move forward to the feeding position. Only when the operator completes the placement preparation work, closes the second protective cover 412, that is, the safety lock 42 is in the locked state, and the photoelectric sensor 43 detects that the mold 1 is placed on the support mechanism 20, and the safety condition is met, will the drive mechanism 40 drive the support mechanism 20 with the mold 1 to move forward to the feeding position. The feeding device of this molding press uses an interlocking mechanism formed by the safety door lock 42 and the safety sensor 43. It will only move to the feeding position when the supporting mechanism 20 holding the mold 1 meets the safety conditions, thereby effectively avoiding safety accidents such as pinching or collision injuries to the operator during the operation of the equipment. In addition, the safety guard 41 provides a physical barrier during the movement of the supporting mechanism 20, further preventing the operator from accidentally touching it during the operation of the supporting mechanism and causing accidental injury to the operator.
