Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a fast-discharging plastic mold. Background Art

[0002] Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The coordinated changes of the mold convex and concave molds and the auxiliary molding system can process a series of plastic parts of different shapes and sizes. After the plastic parts are processed, they need to be adjusted to a certain height or taken out. The operator needs to pick them up. If the hand is not stable, it may cause bumps on the surface of the plastic parts, resulting in a lack of certain height adjustment of the processed plastic parts.

[0003] In order to solve the problem of adjusting the heights of plastic parts after processing, a solution of a plastic mold processing fixture (Announcement No.: CN218227462U) was discovered through search. When in use, the plastic mold can be clamped and fixed by the provided mounting plate, threaded rod, turning handle, limiting rod and clamping plate, thereby improving the fixation and stability of the placement of the plastic mold. At the same time, through the provided storage box, turning rod, turntable, No. 1 bevel gear, rotating cylinder, No. 2 bevel gear, threaded column, placement plate, sleeve and sleeve rod, after the plastic mold is placed on the upper surface of the placement plate, the plastic mold can be raised and lowered conveniently and quickly, thereby improving the processing efficiency of the plastic mold.

[0004] However, when taking out the material from the plastic mold, after the plastic mold is processed, the operator usually takes out the processed molded part.

[0028] A lifting plate 13, the lifting plate 13 is arranged inside the support seat 9, the top of the lifting plate 13 is connected with a lifting column 12, the lifting column 12 passes through the support seat 9 and the lower mold 8 and is connected with a top plate 11, a rubber pad is arranged on the surface of the top plate 11, and the lifting plate 13 can drive the lifting column 12 and the top plate 11 to move;

[0029] A driving mechanism is disposed inside the support seat 9 , and the gear plate 17 of the driving mechanism drives the gear 22 to rotate, thereby driving the lifting column 12 and the top plate 11 to move upward.

[0030] The driving mechanism includes a threaded barrel 16 inside the support seat 9, the gear 22 is sleeved on the surface of the threaded barrel 16, and a threaded column 21 is screwed inside the threaded barrel 16. When the gear 22 drives the threaded barrel 16 to rotate, the threaded column 21 inside the threaded barrel 16 will be screwed out from the inside of the threaded barrel 16, and the threaded column 21 is connected to the lifting plate 13, and the tooth plate 17 engages with the gear 22, and the tooth plate 17 can drive the gear 22 to rotate. A driving column 20 is connected to one side of the tooth plate 17, and the driving column 20 is connected to a push ring 10 after passing through the support seat 9. Pushing the push ring 10 can drive the driving column 20 to move.

[0031] The inner side of the support seat 9 is connected to a fixed frame 14, and the interior of the fixed frame 14 is connected to a spring 25, and one end of the spring 25 is connected to a movable plate 23. After the movable plate 23 moves inside the fixed frame 14, the spring 25 inside the fixed frame 14 will be squeezed by the movement of the movable plate 23, so that the spring 25 is compressed, and one end of the movable plate 23 is connected to a connecting column 15, and the connecting column 15 passes through the fixed frame 14 and is connected to one side of the tooth plate 17. After the tooth plate 17 moves, the tooth plate 17 will drive the connecting column 15 and the movable plate 23 to move.

[0032] A first slide groove 24 is provided inside the fixed frame 14 , and both ends of the movable plate 23 are slidably connected inside the first slide groove 24 . The first slide groove 24 limits the position of the movable plate 23 .

[0033] A slider 19 is connected to the bottom of the driving column 20, and a second slide groove 18 for slidingly connecting the slider 19 is opened inside the support seat 9. The slider 19 at the bottom of the driving column 20 will slide inside the second slide groove 18, so that the second slide groove 18 can limit the position of the movement of the slider 19 and the driving column 20, and the movement is always in a horizontal state.

[0034] The two sides of the top of the support seat 9 are connected to limiting columns 5, and the limiting columns 5 are sleeved with movable plates 4, which are slidably connected to the surfaces of the limiting columns 5, so that the limiting columns 5 limit the position of the movement of the movable plate 4, and the bottom of the movable plate 4 is connected to an upper mold 7, and the inside of the frame 1 is connected to a cylinder 6, and the push rod of the cylinder 6 is connected to the top of the movable plate 4.

[0035] Specifically, when in use, the cylinder 6 is started, and the push rod of the control cylinder 6 drives the movable plate 4 to move downward on the limiting column 5, so that the limiting column 5 limits the position of the movement of the movable plate 4, so that the upper mold 7 at the bottom of the movable plate 4 is adapted to be inserted into the interior of the lower mold 8, and the bottom of the upper mold 7 does not contact the concave bottom of the lower mold 8, so that a certain space (that is, the space is the space of the plastic mold that needs to be formed) is reserved. Figure 2 The liquid material is then poured into the funnel 2, and then flows into the lower mold 8 through the liquid inlet pipe 3, and enters and fills the B interval, so that the lower mold 8 is processed into a complete plastic mold, and then the push rod of the cylinder 6 drives the movable plate 4 and the upper mold 7 to move, so that the movable plate 4 and the upper mold 7 move to the initial position;

[0036] Then, the push ring 10 is pushed, so that the push ring 10 drives the driving column 20 to move, so that the driving column 20 will move toward the inside of the support seat 9, so that the driving column 20 drives the tooth plate 17 to move. Since the tooth plate 17 and the gear 22 are meshed, the gear 22 and the threaded barrel 16 can be driven to rotate. During the rotation of the threaded barrel 16, the threaded column 21 will be screwed out, so that the threaded column 21 is separated from the inside of the threaded barrel 16, and the threaded column 21 will drive the lifting plate 13, the lifting column 12 and the top plate 11 to move upward. After the top plate 11 moves upward, the processed plastic mold will be ejected, so as to facilitate rapid material removal and reduce the workload of the operator.

[0037] During the movement of the driving column 20, the slider 19 at the bottom of the driving column 20 will slide into the second slide groove 18, so that the second slide groove 18 can limit the movement of the slider 19 and the driving column 20, so that the movement is always in a horizontal state;

[0038] When the tooth plate 17 moves to the left, the connecting column 15 on one side of the tooth plate 17 drives the moving plate 23 to move toward the inside of the fixed frame 14, and the moving plate 23 squeezes the spring 25 inside the fixed frame 14, so that the spring 25 is in a compressed state, and the two ends of the moving plate 23 are slidably connected to the inside of the first slide groove 24, and the first slide groove 24 limits the movement of the moving plate 23;

[0039] After the material is taken, the elastic force of the spring 25 is used to push the moving plate 23 and the connecting column 15 to the initial position, and the connecting column 15 drives the tooth plate 17 to move to the right, and the tooth plate 17 drives the gear 22 and the threaded cylinder 16 to rotate in the opposite direction, and the lifting plate 13, the lifting column 12 and the top plate 11 move to the initial position (i.e. Figure 3 The state shown in the figure forms the state for the next material taking, and the driving column 20 and the push ring 10 will also be restored to the initial position, which is convenient for the operator to operate, reduce labor and increase production efficiency.
