Description

Technical Field

[0001] This utility model relates to the field of vacuum forming mold technology, and in particular to a snap-on vacuum forming mold that is easy to replace. Background Technology

[0002] A vacuum forming mold is a tool used in the vacuum forming process. It is mainly used to process thermoplastic sheets into plastic products of various shapes. Its working principle is to first heat the plastic sheet to a softened state, and then use vacuum adsorption or mechanical pressure to make the softened plastic sheet adhere tightly to the surface of the mold. After cooling and solidification, a plastic product with the same shape as the mold cavity can be obtained. It is widely used in the production of products such as plastic cup holders and lunch boxes.

[0003] Currently, the mold cavity and mold of existing vacuum forming molds are a single unit. Therefore, when it is necessary to change the production style, or when a certain part of the mold cavity is worn, damaged or defective, the entire mold may need to be disassembled during maintenance because the mold cavity is fixed. As a result, the staff needs to loosen the multiple bolts and nuts on the mold one by one, which increases the difficulty and time of disassembly. To solve the above problems, we propose a snap-fit ​​vacuum forming mold that is easy to replace. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a snap-fit ​​type vacuum forming mold that is easy to replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A replaceable snap-on blister mold includes a blister mold body 1, an internal cavity of which a mold cavity 2 is placed. A slot 3 is formed on the side of the blister mold body 1, and a connecting block 4 is inserted into the slot 3. One end of the connecting block 4 is connected to a connecting rod 5, which extends through the inner wall of the blister mold body 1 to the outside of the blister mold body 1. The other end of the connecting block 4 is connected to a limiting block 6, which extends through the interior of the blister mold body 1 into the mold cavity 2. A positioning groove adapted to the limiting block 6 is formed on the side of the mold cavity 2. A connecting spring 8 is connected to the side of the connecting block 4, and the other end of the connecting spring 8 is connected to the inner wall of the slot 3.

[0023] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the connecting rod 5 is connected to the pull rod 7 on the side away from the limiting block 6. The inside of the vacuum forming mold body 1 is provided with a receiving groove that matches the pull rod 7. During use, the pull rod 7 can be stored by opening the receiving groove to prevent the pull rod 7 from protruding, thus ensuring the service life of the pull rod 7. The connection of the pull rod 7 makes it easy for the staff to quickly push the connecting rod 5, the connecting block 4 and the limiting block 6 to move laterally, thereby effectively improving the convenience of using this device.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a support plate 10 is inserted into the bottom of the cavity, and a sliding plate 11 is connected to the side of the support plate 10. The interior of the blister mold body 1 is provided with a sliding groove 14 that matches the sliding plate 11. In use, the cooperation between the sliding plate 11 and the sliding groove 14 makes it easy for the staff to lift the mold cavity 2 and the support plate 10. The lifted mold cavity 2 can reduce the obstruction of the staff's hands by the inner wall of the blister mold body 1, so that the staff has more space to pick up and operate. In addition, since the blister mold body 1 used for plastic cup holders and lunch boxes is small in size, the overall volume of the mold cavity 2 is relatively small, which makes the weight of the mold cavity 2 lighter, so that the staff can lift the support plate 10 smoothly.

[0025] Furthermore, refer to Figure 3 and Figure 4It can be seen that the sliding plate 11 has a groove 12 inside, and the inner diameter of the groove 12 is larger than the outer diameter of the operator's finger. By opening the groove 12 with a larger inner diameter, it is easier for the operator to lift the sliding plate 11.

[0026] Furthermore, refer to Figure 3 It can be seen that a sealing plate 13 is fixedly connected to the front of the sliding plate 11, and a receiving groove adapted to the sealing plate 13 is opened inside the blister mold body 1. During use, the sealing operation of the front opening of the sliding groove 14 can be achieved through the sealing plate 13 and the receiving groove opened inside the blister mold body 1, thereby effectively preventing external debris from entering the cavity inside the blister mold body 1, so as to ensure the service life of the blister mold body 1.

[0027] Furthermore, refer to Figure 2 and Figure 5 It can be seen that the upper part of the limiting block 6 is provided with an inclined surface, and the outer wall of the inclined surface is glued with a rubber plate 9. Since the upper part of the limiting block 6 is provided with an inclined surface, when the operator installs a new mold cavity 2, the operator only needs to quickly insert the mold cavity 2 into the interior of the vacuum forming mold body 1, so that the bottom wall of the mold cavity 2 pushes the inclined structure limiting block 6 to move laterally quickly. This can be achieved without the operator manually pulling the pull rod 7, thereby effectively improving the convenience of using this device. With the rubber plate 9 glued with the inclined surface, the inclined surface of the pull rod 7 can be protected, thereby effectively ensuring the service life of the limiting block 6.

[0028] Working Principle: When using this utility model, the operator can first install the blister mold body 1 in a suitable position using bolts, and then place the plastic sheet into the mold cavity 2. The molding operation of the plastic is then completed by closing the mold. When the operator needs to change the production style or when the mold cavity 2 is worn, the operator can first pull the pulling rod 7 horizontally, which will move the connecting rod 5 at the same time. At this time, the connecting block 4 connected to the side of the connecting rod 5 can slide along the inner wall of the groove 3 under force, and the limiting block 6 connected to the connecting block 4 can be pulled out from the side positioning groove of the mold cavity 2. Then the operator can insert their finger into the slot 12 to drive the sliding plate 11 to slide along the inner wall of the sliding groove 14 under force, which will drive the lifting operation of the support plate 10. At the same time, the mold cavity 2 can be pushed out from the blister mold body 1, so that the operator can quickly take out the mold cavity 2, thereby effectively improving the convenience of using this device. The above is the complete working principle of this utility model.

[0029] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
