[0036] The demoulding mechanism 2 includes a movable die block 21 symmetrically and movably arranged on the static die 12 and a driving column 20 arranged on the movable die 11;

[0037] The two movable modules 21 are driven by the driving column 20 as the mold assembly 1 opens and closes, and move away from or close to the mold cavity 120 in the vertical direction.

[0038] Specifically, a guide column 13 is provided along the diagonal line of the movable mold 11, a guide sleeve corresponding to the guide column 13 is provided on the static mold 12, the movable module 21 is slidably connected to the static mold 12, a butt joint half hole 212 and a structural seam 213 are provided on the movable module 21, and a convex hole is provided on the molding convex head 111.

[0039] The mold set 1 is arranged on an injection molding machine, which is a prior art and will not be described in detail.

[0040] In the above technical solution, during the closing process of the mold group 1, the two movable modules 21 are attached to each other and move in the vertical direction to cooperate with the mold cavity 120 and the molding convex head 111 to clamp into an injection space. After injection molding, during the opening process of the mold group 1, the movable module 21 will move away from the mold cavity 120 in the vertical direction. At this time, the multi-structure movable module 21 is first detached, and the bottom of the multi-structure is demolded by utilizing the pulling force of the mold cavity 120 and the molding convex head 111 on the finished part to ensure that the finished part is adsorbed on the molding convex head 111 which is easy to demold after demolding, so as to facilitate cooperation with subsequent automation steps.

[0041] As an embodiment provided by the present invention, a slope 123 is provided on the static mold 12, and an inclined surface is provided on the movable mold 21. The slope 123 includes a low position, and the movable mold 21 is driven to slide along the slope 123 to the low position and then moves in the vertical direction.

During the process of closing or opening the static mold 12 and the movable mold 11, the inclined surface slides along the slope 123 to allow the two movable modules 21 to slide along the slope 123 as the driving column 20 pushes. When the static mold 12 and the movable mold 11 are about to be closed, or when the mold is initially opened from the closed state, the movable module 21 will be at the low position of the slope 123 and move in the vertical direction to allow the two merged movable modules 21 to approach or move away from the mold cavity 120.

[0043] During injection molding, the movable mold 11 and the static mold 12 are closed, and the driving column 20 moves along the static mold 12, and drives the two movable modules 21 to approach the center of the mold group 1. After approaching, the movable modules 21 reach the low position of the slope 123 and approach the movable mold 11 in the vertical direction, so that the two movable modules 21 fit the mold cavity 120 and clamp with the molding convex head 111 to form a molding cavity, and then the injection molding is cooled. After cooling, the movable mold 11 and the static mold 12 are opened. At this time, the movable module 21 is first driven with the mold opening, and moves away from the movable mold 11 in the vertical direction at a low position to be demolded first, and then moves with the mold opening, and the finished part will be adsorbed on the molding convex head 111 on the movable mold 11.

After approaching, the movable module 21 reaches the low position of the slope 123, and approaches the movable module 21 in the vertical direction, so that the two movable modules 21 fit the mold cavity 120, and clamp with the molding convex head 111 to form a molding cavity. At the same time, the movable module 21 crosses the sensing range of the sensor 41, and gives a signal of successful mold closing. Then injection molding is carried out. After injection molding, the cooling air outlet block outputs cold air to the movable cavity for cooling. After cooling, the movable mold 11 and the static mold 12 are opened. At this time, the movable module 21 is first driven with the mold opening, and moves away from the movable mold 11 in the vertical direction at a low position to perform the first demolding, and then moves with the continuous mold opening.

At the same time, the movable module 21 passes the sensing range of the sensor 41, giving a signal of successful mold closing, followed by injection molding. After injection molding, the cooling air outlet block outputs cold air to the movable cavity for cooling. After cooling, the movable mold 11 and the static mold 12 are opened.

When the mold is in the open mold state, the active module 21 will be at the high position of the slope 123 and fit the heating block 3. Then, before injection molding, the heating block 3 will heat the active module 21 for preheating. The preheating can slow down the cooling of the plastic melt that fits the active module 21 in the initial stage of injection molding. The flowing molten liquid can reduce the weld seam, assist plasticity, and increase the integrity of the small structure on the finished product.

At this time, the movable mold 21 will be at the high position of the slope 123 and fit the heating block 3 for preheating. When injection molding is required, the movable mold 11 and the static mold 12 are closed. The driving column 20 moves along the static mold 12 and drives the two movable molds 21 to move closer to the center of the mold group 1. After moving closer, the movable mold 21 reaches the low position of the slope 123 and moves toward the movable mold 11 in the vertical direction.

After injection molding, the cooling air outlet block outputs cold air to the movable cavity for cooling. After cooling, the movable mold 11 and the static mold 12 are opened. At this time, the movable module 21 is first driven with the mold opening. Because of the pulling of the third spring 241, the coupling gear 231 located at the first end of the movable groove rotates, driving the movable module 21 to move in the vertical direction, and as it continues to move, the coupling gear 231 is engaged in the locking sleeve 2321 and locked, so as to pull the movable module 21 through the connecting plate 23 to first demold, and then as the mold opening continues to move, the finished part will be adsorbed on the molding protrusion 111 on the movable mold 11.

[0064] As the best embodiment provided by the present invention, a wind collecting cover 243 covering the through hole 244 is provided on the guide bar 242, and the wind collecting cover 243 is an elastic metal block.

[0065] Specifically, the air collecting hood 243 is made of elastic metal and can be deformed. The air collecting hood 243 increases the ability of the guide bar 242 to receive cold air. When the active module 21 moves in the vertical direction, the air collecting hood 243 will slide into the active module 21 along the guide bar 242 to increase the damping force between the active module 21 and the guide seat 24.

[0066] Before injection molding, the static mold 12 and the movable mold 11 are in an open mold state. At this time, the movable module 21 will be at a high position of the slope 123 and fit the heating block 3 for preheating. When injection molding is required, the movable mold 11 and the static mold 12 are closed, and the driving column 20 moves along the static mold 12. At this time, the receiving plate 221 pushes and moves with the driving column 20. At the same time, the connecting plate 23 slides along the receiving plate 221 to stretch the second spring 230, so that the two movable modules 21 move toward the center of the mold group 1 along the slope 123. After moving together, the movable module 21 reaches the low position of the slope 123. At this time, the connecting plate 23 will move in the vertical direction to make the limiting cover 232, the rack part and the coupling gear 231 move together. At this time, the coupling gear 231 rotates to the first end of the movable groove with the movement, and rotates along the first end to drive the tooth plate 211 to move in the opposite direction of the connecting plate 23 and approach the movable mold 11. At this time, the third spring 241 pushes the guide seat 24 to fit the low position of the slope 123 , and guides the movable module 21 through the guide strip 242, so that the two movable modules 21 fit the mold cavity 120, and are clamped with the molding convex head 111 to form a molding cavity. At the same time, the movable module 21 crosses the sensing range of the sensor 41, giving a signal of successful mold closing, followed by injection molding. After injection molding, the cooling air outlet block outputs cold air to the movable cavity for cooling. During cooling, the cold air enters the movable module 21 along the air collecting hood 243 for cooling. After cooling, the movable mold 11 and the static mold 12 are opened. At this time, the movable module 21 is first driven with the mold opening. Because of the pulling of the third spring 241, the coupling gear 231 located at the first end of the movable groove rotates, driving the movable module 21 to move in the vertical direction, and as it continues to move, the coupling gear 231 is engaged in the locking sleeve 2321 and is locked, so as to pull the movable module 21 through the connecting plate 23 to first demold, and then as the mold opening continues to move, the finished part will be adsorbed on the molding convex head 111 on the movable mold 11.

[0067] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
