Description

Technical Field

[0001] This utility model relates to the field of demolding mechanism technology, specifically a simplified demolding structure for molds. Background Technology

[0002] The demolding mechanism is an important device in a mold used to remove the molded part from the mold cavity or core. When the mold is opened, it removes the plastic product from the molded part of the mold, so that it can leave the mold smoothly.

[0003] Currently, there are many types of undercut demolding structures on molds in existing technologies. In addition to common inclined ejectors, sliders, and inward sliders, with the diversification of product structures and shapes, it is often not just a simple one-way core pulling demolding, but also a need to solve the undercutting problem in two directions. In view of this, we propose a simplified mold demolding structure. Utility Model Content

[0004] The main objective of this invention is to provide a simplified mold release structure that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a simplified mold demolding structure, including a pressure plate, a sliding groove on the pressure plate, a slider slidably connected to the sliding groove, an inward sliding block fixedly connected to the slider, an inclined stop block slidably connected to the side wall of the inward sliding block, a LOGO insert slidably connected to the inward sliding block, and a demolding mechanism provided inside the inward sliding block, the demolding mechanism including a movable groove, the movable groove being located inside the inward sliding block.

[0006] Preferably, a movable block is slidably connected to the movable slot, and the upper part of the movable block is fixedly connected to the lower end of the LOGO insert.

[0007] Preferably, a return spring is fixedly connected to the movable block, and the end of the return spring away from the movable block is fixedly connected to an inner wall of the movable groove.

[0008] Preferably, the pressure plate is provided with a second movable groove, and a rotating rod is rotatably connected in the second movable groove, and an arc-shaped lever is fixedly connected to the rotating rod.

[0009] Preferably, the arc-shaped lever and the movable groove are connected by a torsion spring.

[0010] Preferably, the end of the retractable slider away from the inclined stop is provided with an inclined guide post. During mold closing, by pressing down on the inclined stop, the inclined stop touches the arc-shaped lever. With the cooperation of the rotating rod and the second movable groove, the end of the arc-shaped lever away from the inclined stop is pushed upward. With the cooperation of the first movable groove, the movable block moves upward. The upward movement of the movable block causes the LOGO insert to move upward as well. When opening the mold, simply release the inclined stop. Under the elastic reset action of the return spring, the movable block and the LOGO insert will retract together into the first movable groove. At the same time, with the cooperation of the torsion spring and the rotating rod, the arc-shaped lever will reset, causing the inclined stop to spring back and reset. This allows the LOGO insert on the retractable slider to disengage and open the mold. The operation is simple and simplifies the mold demolding structure. By installing the return spring in the first movable groove, the return spring is in a compressed state during the demolding stage. After the demolding action is completed, the return spring releases its elastic potential energy, effectively solving the problem of the LOGO insert being snapped backward in the retractable slider.

[0011] This utility model provides a simplified demolding structure for molds. It has the following beneficial effects:

[0012] (1) The mold simplifies the demolding structure. When the mold is closed, the inclined block is pressed down, so that the inclined block touches the arc lever. With the cooperation of the rotating rod and the second movable groove, the end of the arc lever away from the inclined block will be pushed upward. With the cooperation of the first movable groove, the movable block will move upward. The upward movement of the movable block will also drive the LOGO insert to move upward. When the mold is opened, the inclined block is released. Under the elastic reset action of the reset spring, the movable block and the LOGO insert will be pushed back into the first movable groove. At the same time, with the cooperation of the torsion spring and the rotating rod, the arc lever will be reset, so that the inclined block will spring back and reset, and then the LOGO insert on the inner sliding block will be released and the mold will be opened. The operation is simple and the mold demolding structure is simplified.

[0013] (2) The mold simplifies the demolding structure by installing the reset spring in the movable groove. During the demolding stage, the reset spring is in a compressed state. After the demolding action is completed, the reset spring releases its elastic potential energy, which effectively solves the problem of the LOGO insert being snapped backward in the inner sliding block.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model proposes a simplified mold demolding structure, including a pressure plate 1, a sliding groove 2 on the pressure plate 1, a slider 3 slidably connected to the sliding groove 2, an inwardly retractable slider 4 fixedly connected to the slider 3, an inclined stop block 6 slidably connected to the side wall of the inwardly retractable slider 4, a LOGO insert 7 slidably connected to the inwardly retractable slider 4, and a demolding mechanism 9 provided inside the inwardly retractable slider 4. The demolding mechanism 9 includes a movable groove 91, which is located inside the inwardly retractable slider 4.

[0024] In this embodiment of the utility model, in order to enable the demolding mechanism 9 to operate better, specifically, the movable groove 91 is slidably connected to the movable block 92, the upper part of the movable block 92 is fixedly connected to the lower end of the LOGO insert 7, the movable block 92 is fixedly connected to the return spring 93, the end of the return spring 93 away from the movable block 92 is fixedly connected to the inner wall of the movable groove 91, the pressure plate 1 is provided with the movable groove 94, the movable groove 94 is rotatably connected to the rotating rod 95, the rotating rod 95 is fixedly connected to the arc lever 96, and the arc lever 96 and the movable groove 94 are connected by the torsion spring 97.

[0025] Furthermore, the end of the inward sliding block 4 away from the inclined stop block 6 is provided with an inclined guide post 8. During mold closing, by pressing down on the inclined stop block 6, the inclined stop block 6 touches the arc-shaped lever 96. With the cooperation of the rotating rod 95 and the second movable groove 94, the end of the arc-shaped lever 96 away from the inclined stop block 6 is pushed upward. With the cooperation of the first movable groove 91, the movable block 92 moves upward. The upward movement of the movable block 92 will also cause the LOGO insert 7 to move upward. When opening the mold, simply release the inclined stop block 6. Under the elastic reset action of the return spring 93, the movable block 92 and the LOGO insert 7 will retract into the first movable groove 91. At the same time, with the cooperation of the torsion spring 97 and the rotating rod 95, the arc-shaped lever 96 will reset, thereby causing the inclined stop block 6 to spring back and reset. This allows the LOGO insert 7 on the inner sliding block 4 to disengage and open the mold, simplifying the operation and the mold demolding structure. By installing the return spring 93 in the movable slot 91, the return spring 93 is in a compressed state during the demolding stage. After the demolding action is completed, the return spring 93 releases its elastic potential energy, effectively solving the problem of the LOGO insert 7 being backward-facing inside the inner sliding block 4. The movement of the inner sliding block 4 is controlled by the inclined guide post 8. At the same time, the LOGO insert 7 only needs to move downward by 0.3-0.5mm to achieve disengagement. Before the LOGO insert 7 is reset, the inner sliding block 4 is stationary. The inclination of the inner sliding block 4 is 7 degrees. The inclined guide post 8 and the inner sliding block 4 have a gap of at least 0.5mm on each side and both need to be opened by 4mm to ensure the movement of the inner sliding block 4.

[0026] In this invention, during mold closing, pressing down on the inclined stop 6 causes it to contact the arc-shaped lever 96. With the cooperation of the rotating rod 95 and the second movable groove 94, the end of the arc-shaped lever 96 away from the inclined stop 6 is pushed upwards. With the cooperation of the first movable groove 91, the movable block 92 moves upwards. The upward movement of the movable block 92 causes the LOGO insert 7 to move upwards as well. When opening the mold, simply releasing the inclined stop 6 causes the movable block 92 and the LOGO insert 7 to retract into the first movable groove 91 under the elastic reset action of the return spring 93. Simultaneously, with the cooperation of the torsion spring 97 and the rotating rod 95, the arc-shaped lever 96 is reset, causing the inclined stop 6 to spring back and reset, thus disengaging the LOGO insert 7 on the inward sliding block 4 and opening the mold.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
