Description

Technical Field

[0001] This utility model relates to the field of liquid culture medium production technology, specifically to a molding die for a liquid culture medium storage container that is easy to demold. Background Technology

[0002] The reference patent title is: A Plastic Bottle Injection Blow-Stretch Molding Device (Authorization Announcement No.: CN220373889U, Authorization Announcement Date: 2024.01.23). It includes a fixed base, a fan, a mold body a, a condensate pipe, and a mold body b. Both mold bodies a and b have plastic bottle molding cavities. A top plate is slidably mounted on the inner wall of the bottom of each molding cavity, and multiple electric push rods a are mounted at the bottom of the top plate. The condensate pipe is located inside mold bodies a and b, and inlet and outlet pipes are located on both sides of mold bodies a and b. The fan is located inside mold bodies a and b. This device can accelerate the cooling speed of the bottle cap, shorten the cooling time, thereby improving production efficiency. It also makes it easier to demold the plastic bottle after molding and facilitates material unloading and collection by operators, thus reducing unloading time and workload.

[0003] Based on the above-mentioned documents: In the blow molding production of liquid culture medium storage containers (such as plastic culture bottles, reagent bottles, etc.), traditional molds mostly rely on manual demolding or use complex linkage demolding mechanisms. Manual demolding not only increases labor costs, but also easily causes scratches, deformation or even cracks on the container surface due to uneven operating force. Complex linkage mechanisms have problems such as slow response and difficult maintenance. After the molded container is removed from the mold, it usually falls directly to the collection device. Due to the lack of a buffer structure, the hard contact between the container and the collection component can easily cause damage such as bottle mouth cracking and bottle body dent. For culture medium containers with thin walls, this damage is more obvious. Therefore, this utility model provides a liquid culture medium storage container molding mold that is easy to demold.

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 Figure 1-4 This utility model provides a technical solution:

[0024] A molding die for a liquid culture medium storage container that facilitates demolding includes a workbench 1, a buffer collection assembly 2 at the bottom of the workbench 1, and a molding mechanism 3 at the top of the workbench 1. The molding mechanism 3 includes:

[0025] The molding assembly 31 includes support plates 311 symmetrically installed on both sides of the top of the workbench 1. A sliding rod 312 is slidably connected inside the support plate 311. A mold plate 313 is fixedly connected to one end of the sliding rod 312. A demolding rod 314 is slidably connected inside the mold plate 313. A connecting plate 315 is fixedly connected to one end of the demolding rod 314. A return spring 316 is fixedly connected to one side of the connecting plate 315. One end of the return spring 316 is fixedly connected to the surface of the mold plate 313.

[0026] The drive assembly 32 is located on the outside of the support plate 311 and is used to drive the mold plate 313 to slide in the horizontal direction to realize the mold closing or opening operation.

[0027] A top block is installed at the ejector end of the ejector rod 314. The diameter of the top block is larger than that of the ejector rod 314 and slides in the slot opened on the inner side of the mold plate 313. When the return spring 316 is not affected by external force, the top block is located in the inner cavity of the slot opened on the inner side of the mold plate 313. The surface of the top block is fully in contact with and parallel to the inner surface of the mold plate 313, which facilitates the subsequent container molding.

[0028] By clearly defining the vertically sliding demolding rod 314 and the return spring 316 working together, the molded container can be automatically and accurately ejected from the mold groove when the mold is opened, improving the convenience of container demolding and avoiding product deformation or surface damage caused by manual demolding. At the same time, the return spring 316 can ensure the stable return of the demolding rod 314, significantly improving demolding efficiency and product qualification rate.

[0029] In this embodiment, the drive assembly 32 includes a drive cylinder 321 installed on the outside of the support plate 311. The output end of the drive cylinder 321 is slidably connected to a drive rod 322. The surface of the drive rod 322 is slidably connected to the inside of the support plate 311. One end of the drive rod 322 passes through the connecting plate 315 and is fixedly connected to the surface of the mold plate 313.

[0030] There are two sets of symmetrically designed drive cylinders 321, and both are started and stopped synchronously via control panel 5.

[0031] In this embodiment, a symmetrical limiting plate 4 is fixedly connected to the top of the workbench 1. The interior of the limiting plate 4 is slidably connected to the surface of the drive rod 322. A control panel 5 is installed on the top of the workbench 1. The control panel 5 is electrically connected to the drive cylinder 321 to control its start and stop.

[0032] In this embodiment, a cooling medium inlet 6 is installed on the top of the mold plate 313, and a cooling medium outlet 7 is installed on the top of the mold plate 313.

[0033] Both the cooling medium inlet 6 and the cooling medium outlet 7 are connected to the cooling flow channel inside the mold plate 313.

[0034] In this embodiment, the buffer collection assembly 2 includes a support block 21 installed at the bottom of the workbench 1. Support rods 22 are rotatably connected to both sides of the support block 21. A collection mesh frame 23 is installed at one end of the support rod 22 by bolts. The collection mesh frame 23 is designed to be inclined. A buffer spring 24 is fixedly connected to the top of the support rod 22. One end of the buffer spring 24 is fixedly connected to the bottom of the workbench 1.

[0035] The collecting frame 43 is set at an angle with the lower end facing the discharge direction.

[0036] In this embodiment, a material discharge slot 8 is provided at the center of the top of the workbench 1, and the collection mesh frame 23 is located directly below the material discharge slot 8.

[0037] By setting up a buffer collection component 2, and using a collection mesh frame 23 that is tilted with the lower end facing the discharge direction, in conjunction with a buffer spring 24 and a rotatable support rod 22, the product can be guided to discharge in an orderly manner after demolding, and the impact of falling can be absorbed by the buffer spring 24, effectively reducing cracks or deformations caused by hard contact with the product and reducing losses during the collection process.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] After the liquid culture medium storage container is blow-molded, the drive cylinder 321 is activated through the control panel 5 to drive the drive rod 322 to retract, so that the mold plate 313 separates in the horizontal direction to realize the mold opening operation. During the mold opening process, the sliding rod 312 slides inside the support plate 311. The sliding rod 312 can limit the sliding of the mold plate 313. At the same time, the container creates a gap with the inner wall of the cavity due to cooling and shrinkage, but it may still stick locally. During the sliding process, the mold plate 313 will drive the demolding rod 314, the return spring 316 and the connecting plate 315 to slide synchronously. During the sliding process, the connecting plate 315 will contact the surface of the limiting plate 4, so that the demolding rod 314 remains stationary and the return spring 316 is compressed. When the demolding rod 314 stops sliding due to limitation, the mold plate 313 will continue to slide. At this time, one end of the demolding rod 314 will contact the surface of the container formed in the inner cavity of the mold groove, pushing the container out from the inner wall of the mold groove, so that it is completely separated from the mold groove of the mold plate 313.

[0040] After demolding, the container falls vertically through the material drop chute 8 of the workbench 1 under the action of gravity and falls into the collection frame 23 directly below. The collection frame 2343 is designed to be inclined at 30°-45°. When the container contacts the frame, the support rod 22 rotates slightly around the support block 21 under the impact. The buffer spring 24 is compressed synchronously and absorbs the impact force to prevent the container from cracking or deforming due to hard contact. Then, the container slides along the inclined frame to the lower end of the discharge port and falls into the external collection box, completing one molding cycle.
