Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plastic part demolding, and particularly relates to a high-efficiency plastic part demolding device. BACKGROUND

[0002] In the production and processing of plastic parts, the plastic parts are generally produced through injection molding. In the early stage of plastic part design, the plastic parts are processed through flexible injection molding in small batches to prepare for the opening of a metal mold. Since the mold for flexible injection molding is generally made of silica gel, the contact friction between the silica gel and the plastic parts is large. Therefore, it is necessary to perform demolding operation between the plastic parts and the mold.

[0003] In the production and processing of plastic parts, the plastic parts are generally demolded from the mold by a worker manually opening the mold. However, after the plastic product is processed and formed by the existing part of the thermoforming machine, the upper and lower processing molds are separated from each other, the formed plastic product is embedded in the forming mold, and it is not convenient to automatically separate and demold. The plastic product and the mold need to be controlled to be separated from each other in the subsequent process, thereby increasing the process procedure. Therefore, the application provides a high-efficiency plastic part demolding device. SUMMARY

[0004] In view of the defects of the prior art, the application provides a high-efficiency plastic part demolding device, which solves the problem that the formed plastic product is embedded in the forming mold and is not convenient to automatically separate and demold, and the plastic product and the mold need to be controlled to be separated from each other in the subsequent process.

[0005] To achieve the above object, the application provides the following technical scheme: a high-efficiency plastic part demolding device, comprising a first mold closing mechanism, a second mold closing mechanism and a mold closing table.

[0006] The bottom end of the first mold closing mechanism and below the mold closing table are provided with a support, the inside of the first mold closing mechanism and the outer side are fixedly installed with a first driving motor, the outer side of the first driving motor is connected with a first driving rod, the outer side of the first driving rod is sleeved with a first fixed plate, the outer side of the first fixed plate is vertically installed with a first moving plate, the inside of the first moving plate is inserted with a first movable rod, one end of the first moving plate relative to the first movable rod is connected with a first reciprocating rod, the other end of the first reciprocating rod away from the first moving plate is fixedly installed with a first motor, the outer side of the first moving plate is connected with a first hydraulic motor, and the outer side of the first hydraulic motor is movably connected with a first mold closing plate.

[0007] A second drive motor is fixedly installed inside and on the outside of the second mold closing mechanism. A second drive rod is connected to the outside of the second drive motor. A second fixed plate is sleeved on the outside of the second drive rod. A second movable plate is vertically installed on the outside of the second fixed plate. A second movable rod is inserted into the inside of the second movable plate. A second reciprocating rod is connected to one end of the second movable plate relative to the second movable rod. A second motor is fixedly installed at the end of the second reciprocating rod away from the second movable plate. A second hydraulic motor is connected to the outside of the second movable plate. A second mold closing plate is movably connected to the outside of the second hydraulic motor.

[0008] As a preferred embodiment of the invention, the mold clamping table is held between the first mold clamping mechanism and the second mold clamping mechanism, and is located above the support.

[0009] As a preferred embodiment of the invention, the first mold closing mechanism and the second mold closing mechanism are symmetrical and have the same structure.

[0010] The technical solution of this invention has the following beneficial effects:

[0011] 1. This high-efficiency plastic part demolding device uses a first and second mold-closing platen to press against each other, thereby pressing the plastic part shell above the mold-closing table and closing the mold. This ensures a precise, gapless mold-closing of the plastic part shell. After mold closing is complete, two sets of motors drive the device in opposite directions, achieving the demolding operation and demolding the plastic part shell.

[0012] 2. This high-efficiency plastic part demolding device starts by activating the first drive motor inside the first mold closing mechanism. The first drive motor then starts working and drives the first drive rod to rotate. The first drive rod then controls the first fixed plate to move, thereby controlling the first fixed plate to adjust its position and find a suitable position to align with the plastic part shell above the mold closing table, which facilitates mold closing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please see Figures 1-5 A high-efficiency plastic part demolding device includes a first mold closing mechanism 1, a second mold closing mechanism 2, and a mold closing table 3;

[0023] A bracket 11 is provided at the bottom of the first mold closing mechanism 1 and below the mold closing table 3. A first drive motor 12 is fixedly installed inside the first mold closing mechanism 1 and on the outside. A first drive rod 13 is connected to the outside of the first drive motor 12. A first fixed plate 14 is sleeved on the outside of the first drive rod 13. A first moving plate 15 is vertically installed on the outside of the first fixed plate 14. A first movable rod 16 is inserted into the inside of the first moving plate 15. A first reciprocating rod 17 is connected to one end of the first moving plate 15 relative to the first movable rod 16. A first motor 18 is fixedly installed at the end of the first reciprocating rod 17 away from the first moving plate 15. A first hydraulic motor 19 is connected to the outside of the first moving plate 15. A first mold closing plate 110 is movably connected to the outside of the first hydraulic motor 19.

[0024] A second drive motor 22 is fixedly installed inside and on the outside of the second mold closing mechanism 2. A second drive rod 23 is connected to the outside of the second drive motor 22. A second fixed plate 24 is sleeved on the outside of the second drive rod 23. A second movable plate 25 is vertically installed on the outside of the second fixed plate 24. A second movable rod 26 is inserted into the inside of the second movable plate 25. A second reciprocating rod 27 is connected to one end of the second movable plate 25 relative to the second movable rod 26. A second motor 28 is fixedly installed at the end of the second reciprocating rod 27 away from the second movable plate 25. A second hydraulic motor 29 is connected to the outside of the second movable plate 25. A second mold closing plate 210 is movably connected to the outside of the second hydraulic motor 29.

[0025] By activating the first drive motor 12 inside the first mold clamping mechanism 1, the first drive motor 12 starts working and drives the first drive rod 13 to start rotating. The first drive rod 13 then controls the first fixed plate 14 to move, thereby controlling the first fixed plate 14 to adjust its position and find a suitable position to align with the plastic part housing above the mold clamping table 3, so as to facilitate mold clamping.

[0026] By activating the first motor 18, the first motor 18 then moves the first reciprocating rod 17 inward, pressing the first moving plate 15 inward. The first moving plate 15 then moves above the first movable rod 16, and the first moving plate 15 then drives the first hydraulic motor 19 connected to it to move synchronously. The first hydraulic motor 19 controls the hydraulic pressure to press the first closing plate 110 inward. By activating the second motor 28, the second motor 28 then moves the second reciprocating rod 27 inward, pressing the second moving plate 25 inward. The second moving plate 25 then moves above the second movable rod 26, and the second moving plate 25 then drives the second hydraulic motor 29 connected to it to move synchronously. The second hydraulic motor 29 controls the hydraulic pressure to press the second closing plate 210 inward. The first closing plate 110 and the second closing plate 210 then come closer together and press against each other, thereby pressing the plastic part shell above the mold closing table 3, thus closing the plastic part shell, making the mold closing of the plastic part shell precise and without gaps. After the mold is closed, the two sets of motors are driven in opposite directions to achieve the reverse movement of the equipment, thereby realizing the demolding operation and demolding of the plastic part shell.

[0027] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below:

[0028] Working principle: In use, the plastic part housing to be molded is placed above the mold closing table 3. The first drive motor 12 inside the first mold closing mechanism 1 is started, and the first drive motor 12 starts to work, which in turn drives the first drive rod 13 to rotate. The first drive rod 13 then controls the first fixed plate 14 to move, thereby controlling the position adjustment of the first fixed plate 14 to find a suitable position and align it with the plastic part housing above the mold closing table 3 for easy mold closing. Then the first motor 18 is started, and the first motor 18 then drives the first reciprocating rod 17 to move inward and press the first moving plate 15 inward. The first moving plate 15 then moves above the first movable rod 16, and the first moving plate 15 then drives the first hydraulic motor 19 connected to it to move synchronously. The first hydraulic motor 19 controls the hydraulic pressure to press the first mold closing plate 110 inward.

[0029] By activating the second motor 28, the second motor 28 moves the second reciprocating rod 27 inward, pressing the second moving plate 25 inward. The second moving plate 25 then moves above the second movable rod 26, and subsequently drives the connected second hydraulic motor 29 to move synchronously. The second hydraulic motor 29 controls the hydraulic pressure, pressing the second closing plate 210 inward. The first closing plate 110 and the second closing plate 210 then move closer together, pressing against the plastic part housing above the mold closing table 3, thus closing the mold. After mold closing is complete, the two sets of motors are driven in the opposite direction to achieve reverse movement of the equipment, thereby realizing the demolding operation and demolding the plastic part housing.
