Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to a mold mechanism for controlling the mold opening action. Background Technology

[0002] In the current field of mold manufacturing and application, the mold mechanism widely used to control the mold opening action has the following structure: Figure 1 As shown. This mold mechanism mainly uses the cooperation of resin opener 1 and spring to realize the mold opening action, that is, to realize the separation action between the two movable plates 2 and 3.

[0003] However, long-term practical application has revealed some significant problems with this mold mechanism. Firstly, the resin opener / closer easily generates adhesive powder during frequent use. Once this powder falls off, it can easily mix into the product being molded, severely impacting product quality, causing defects, or even rendering the product unusable. This significantly increases production costs and reduces production efficiency.

[0004] On the other hand, as a key component providing the separation power, the spring is prone to elastic failure after prolonged extension and contraction. Spring failure directly affects the accuracy and stability of the mold opening action, thus impacting the product's molding quality. To ensure the normal operation of the mold, frequent inspections and replacements of the springs are necessary. This not only increases labor and time costs but also reduces the actual efficiency and lifespan of the mold, negatively impacting the efficient and stable operation of the entire production process. Utility Model Content

[0005] In order to improve product quality and reduce maintenance costs, this application provides a mold mechanism for controlling the mold opening action.

[0006] This application provides a mold mechanism for controlling the mold opening action, which adopts the following technical solution:

[0007] A mold mechanism for controlling mold opening includes a fixed plate, a first movable plate, and a second movable plate. A locking component for maintaining the connection is provided between the first movable plate and the second movable plate. An unlocking component for unlocking the locking component is provided on the fixed plate. When the first movable plate and the second movable plate are in contact, the locking component locks. When the first movable plate and the second movable plate move up and down a preset distance synchronously on the fixed plate, the unlocking component releases the locking component.

[0008] By adopting the above technical solution, when the mold is opened, the fixed plate moves up. During the upward movement, the first movable plate and the second movable plate will move down relative to the fixed plate. When the first movable plate and the second movable plate move up and down synchronously with the fixed plate to reach the preset stroke, the unlocking component releases the locking component. At this time, the first movable plate and the second movable plate separate, and the second movable plate completes the downward mold opening.

[0009] In one embodiment: the locking assembly includes a fixing rod fixedly connected to a first movable plate in a vertical direction, a fixing block slidably connected to a second movable plate, and an elastic element for keeping the fixing block engaged with the fixing rod. The fixing rod is provided with a hook for engaging with the fixing block, and the sliding direction of the fixing block is perpendicular to the fixing rod.

[0010] By adopting the above technical solution, when the first and second movable plates need to be connected, the fixing rod can be engaged with the fixing block. When separation is required, it is only necessary to push the fixing block to overcome the slippage of the elastic element, resulting in a simple structure.

[0011] In one embodiment, the elastic element is a spring.

[0012] In one embodiment: the cross-section of the fixing block is convex, and two limiting strips for sliding the fixing block onto the second movable plate are installed on the second movable plate.

[0013] In one embodiment: the fixing block is provided with a through hole for the fixing rod to pass through, and the hook is provided at the end of the fixing rod.

[0014] In one embodiment: the unlocking component is a lever fixedly mounted on a fixed plate in a vertical direction. The end of the lever is provided with a first wedge-shaped portion. The fixed block is provided with a through hole through which the lever can pass. The through hole of the fixed block is provided with a second wedge-shaped portion that cooperates with the first wedge-shaped portion. When the first movable plate and the second movable plate are in contact, the distance between the first wedge-shaped portion and the second wedge-shaped portion along the length direction of the lever is the preset stroke.

[0015] By adopting the above technical solution, when the first movable plate and the second movable plate move relative to the fixed plate synchronously, the lever moves on the fixed block. However, when the movement distance reaches the preset stroke, the first wedge part contacts the second wedge part. When the relative movement continues, the first wedge part pushes the fixed block compression elastic element to slide through the second wedge part, thereby releasing the locking assembly and separating the first movable plate and the second movable plate.

[0016] In one embodiment, the protrusion direction of the first wedge is the same as the protrusion direction of the hook.

[0017] In one embodiment, the travel distance of the first movable plate on the fixed plate is greater than the preset travel distance.

[0018] By adopting the above technical solution, it is ensured that the first movable plate and the second movable plate can be separated normally.

[0019] In summary, this application has the following advantages: it eliminates the need for mold opening through the cooperation of a resin opener and spring, avoids the problems of resin powder generation and spring maintenance during frequent use, thereby improving product quality and reducing maintenance costs.
