[0002] The molding of rubber products is a key step, which involves mold design, material properties, production process and other aspects. In the production process of rubber products, the product needs to be smoothly taken out of the mold, i.e. demolding. This step is crucial to the quality of the final product and production efficiency. Poor demolding not only causes distortion and tearing of the product, but also may damage the mold, affecting the smoothness of production. At the same time, the increase of production cost has become a problem that must be paid attention to in the development of Chinese manufacturing industry. For rubber parts manufacturing enterprises, it is very important to improve production efficiency, reduce post-process of products, and reduce production cost of products.

[0003] Due to the particularity of rubber products, after the high-pressure and high-temperature molding process, a gap may occur between the middle mold and the lower mold due to the adsorption force of the rubber material at the moment of mold opening. Then, due to the force of gravity, the middle mold falls back down, which is easy to fall on the rubber material, causing the product to be crushed. This also increases the special attention of the later inspection personnel, reduces the qualified rate, and causes the increase of production cost. For example, the rubber mold middle mold lower pressure demolding device in Chinese patent document CN211683133U will have the above problems. SUMMARY

[0034] Embodiment

[0035] In combination Figure 1 The rubber mold with a mold locking structure in the embodiment is provided with a mold locking structure, which can connect the middle mold 62 and the lower mold 63, so that when the upper mold 61 is removed, the middle mold 62 and the lower mold 63 are connected together, the middle mold 62 will not be lifted, thereby avoiding the problem that the rubber material is damaged due to the falling of the middle mold 62.

[0036] Specifically, the rubber mold with the mold locking structure of the embodiment comprises a mold assembly 6, the mold assembly 6 is composed of an upper mold 61, a middle mold 62 and a lower mold 63, and the upper mold 61, the middle mold 62 and the lower mold 63 are connected together from top to bottom when the rubber is molded, and the upper mold 61 and the middle mold 62 are separated in sequence to demold when the molding is completed. In the embodiment, the mold locking structure comprises a buckle piece 5 and a buckle hole 631, which are arranged on the middle mold 62 and the lower mold 63 respectively. The buckle piece 5 can be arranged to be connected with the middle mold 62, and the buckle hole 631 is arranged on the lower mold 63 at this time. Alternatively, the buckle piece 5 can be arranged to be connected with the lower mold 63, and the buckle hole 631 is arranged on the middle mold 62 at this time. The embodiment takes the case that the buckle piece 5 is arranged to be connected with the middle mold 62 and the buckle hole 631 is arranged on the lower mold 63 as an example for introduction.

[0037] In the embodiment, a guide column 3 is connected to the side of the middle mold 62. In the embodiment, the mold assembly 6 is installed on a machine table, and the machine table is provided with a machine table clamp, i.e. a table clamp 12 in the embodiment. The table clamp 12 clamps the guide column 3 and fixes the middle mold 62 through the guide column 3. In the embodiment, a sliding block 2 is sleeved on the guide column 3, and a driving piece 11 is arranged above the table clamp 12. The driving piece 11 pushes the sliding block 2 to move along the length direction of the guide column 3. The driving piece 11 can adopt various forms, such as a motor or a pneumatic cylinder. In the embodiment, the driving piece 11 adopts a pneumatic cylinder. In the embodiment, a limiting piece is arranged at the end of the guide column 3 close to the table clamp 12, i.e. a ring of protruding structures is arranged outward from the periphery of the guide column 3. The limiting piece facilitates the table clamp 12 to clamp the guide column 3 and limits the displacement of the sliding block 2, so that the sliding block 2 only moves between the limiting piece and the middle mold 62.

[0038] In the embodiment, the buckle piece 5 is arranged at the lower end of the sliding block 2 and is just positioned at the position of the lower mold 63. The buckle hole 631 is arranged on the lower mold 63 and corresponds to the position of the buckle piece 5. When the mold needs to be locked, the driving piece 11 pushes the sliding block 2 to move towards the middle mold 62, and drives the buckle piece 5 to move towards the buckle hole 631. When the sliding block 2 contacts the middle mold 62, the buckle piece 5 completely enters the buckle hole 631, thereby locking the middle mold 62 and the lower mold 63.

[0039] In the embodiment, a resilient piece 4 is arranged between the sliding block 2 and the middle mold 62 or the lower mold 63. One end of the resilient piece 4 abuts against the sliding block 2, and the other end abuts against the middle mold 62. In the embodiment, the resilient piece 4 is a spring and is used for resetting the sliding block 2. In the embodiment, the driving piece 11 is not connected with the sliding block 2. When the mold is unlocked, the driving piece 11 is retracted, and the sliding block 2 moves away from the middle mold 62 under the elastic force of the resilient piece 4, thereby resetting the sliding block 2. The buckle piece 5 is completely separated from the buckle hole 631, thereby achieving the unlocking.

[0040] In the embodiment, the contact surface 22 is formed between the slider 2 and the guide column 3, and the gap 21 is formed on both sides of the contact surface 22 away from the guide column 3. In this way, the contact area between the slider 2 and the guide column 3 is reduced, thereby reducing the friction and ensuring the smooth locking and unlocking.

[0041] The above description of the utility model and its embodiments is illustrative and not limiting, and the embodiments shown in the drawings are only one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above description, without departing from the spirit of the utility model, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the utility model.
