Description

Technical Field

[0001] This utility model relates to the field of blister tray production molds, and in particular to a blister tray production mold with a demolding mechanism. Background Technology

[0002] Blister trays, also known as plastic inner trays, are plastic products made by forming rigid plastic sheets into specific grooves using a blister forming process. During the production of blister trays, a blister forming operation is usually performed, which in turn requires the use of blister tray production molds.

[0003] Existing blister tray production molds typically include an upper mold and a mold body. After the upper mold and the mold body are pressed together, a blister forming operation is performed to form a finished blister tray. The finished blister tray is usually located inside the mold cavity of the mold body, and it usually requires the worker's hand to remove the finished blister tray from the mold.

[0004] However, this method can lead to tearing and damage to the finished blister tray during demolding, making it difficult to demold the blister tray production mold after the blister tray has been blistered, which has certain limitations. Utility Model Content

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention utilizes the cooperation of an assembly plate, a push column, a push plate, a drive rod, a drive plate, an extrusion plate, and a spring. The assembly plate and the support plate support the spring, and the spring's elasticity causes the push column to move vertically. The extrusion plate vertically limits the drive plate. After the thermoforming is completed, the extrusion plate moves away from the drive plate, and the compressed spring releases its elasticity, causing the push column and push plate to push the finished thermoformed tray upward. This facilitates the demolding operation of the thermoformed tray after thermoforming, increasing the safety of demolding the finished thermoformed tray. Attached Figure Description

[0024] This utility model provides, for example Figure 1-3 The mold shown is a mold for producing a blister tray with a demolding mechanism, including a mold body 1. The mold body 1 is conducive to performing blister forming operations on the blister tray, and the mold body 1 has a mold cavity 2 inside.

[0025] Furthermore, a demolding mechanism 4 is symmetrically arranged on the mold body 1. The demolding mechanism 4 includes an assembly plate 41, a drive rod 44, a drive plate 45, and an extrusion plate 46. The assembly plate 41 facilitates the support of the bearing plate 49, allowing the drive rod 44 to slide on it, and also facilitates the installation and removal of the bearing plate 49. The drive rod 44 facilitates the movement of the push column 42, allowing the push column 42 to be hidden in the inner cavity of the slide groove, facilitating the vacuum forming operation inside the mold body 1. The drive plate 45 facilitates the movement of the drive rod 44, facilitating the pushing operation of the drive rod 44. The extrusion plate 46 facilitates the rotation of the drive plate 45 to move downwards. Figure 3As shown, the push column 42 and push plate 43 are then limited, concealing them within the inner cavity of the groove and slide. Simultaneously, after the extrusion plate 46 rotates to release the limitation of the drive plate 45, the elastic force of the spring 47 pushes the push column 42 and push plate 43 to move, causing them to push the finished blister tray upwards for demolding. The assembly plate 41 is slidably disposed on the side of the mold body 1. The push column 42 is provided on the side of the assembly plate 41. The push column 42 and push plate 43 facilitate the upward movement of the finished blister tray, thereby facilitating the demolding operation and ensuring the safety of removing the blister tray. The top of the push column 42 is fixedly connected to the push plate 43, and the bottom of the push column 42 is provided with a spring 47. The elastic force of the spring 47 facilitates the movement of the push column 42 and push plate 43, making it easy to demold the blister tray. The spring 47 is in a compressed state as shown... Figure 3 As shown, the drive rod 44 is disposed through the assembly plate 41, the end of the drive rod 44 is located on the push column 42, the drive plate 45 is located on the drive rod 44, and the extrusion plate 46 is rotatably disposed on the top of the drive plate 45.

[0026] Furthermore, a groove is provided at the bottom of the inner wall of the mold cavity 2, and a sliding groove is provided at the bottom of the inner wall of the groove. A square groove is provided on the side of the mold body 1, and an assembly groove 3 is provided on the side of the inner wall of the square groove. The push plate 43 is slidably inserted into the inner cavity of the groove. The push column 42 is slidably inserted into the inner cavity of both the sliding groove and the assembly groove 3.
