Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization molds, in particular to a vulcanization mold with double-sided mold opening. Background Art

[0002] The 3RT machine is a device used for vulcanization of rubber products. This machine adopts a dual-power design and is suitable for use with double-layer or multi-layer molds.

[0003] Chinese patent CN201320845370.6 discloses a "large-size low-quality product production mold structure" with a three-cavity mold structure. A product molding mold structure is provided under the upper mold block, a product molding mold structure is provided on both the upper and lower surfaces of the middle mold block, and a product molding mold structure is provided on the lower mold block.

[0004] Although this mold structure design increases the number of products molded in a single shot, when the mold is used in a 3RT machine, it is difficult to demold the products on the upper surface of the center mold block after it is lifted. This is especially true when producing silicone products. Due to the high viscosity of silicone, the upper surface of the center mold block is extremely difficult to demold and clean.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a vulcanization mold with two-sided mold opening to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Utility Model Content

[0007] In order to overcome the above-mentioned deficiencies in the prior art, the present invention aims to disclose a vulcanization mold with double-sided mold opening, which is used to solve the problem of difficulty in demoulding after the center template in the traditional vulcanization mold is opened.

[0008] The utility model discloses a double-sided vulcanization mold, comprising a lower mold plate, an intermediate mold plate, and an upper mold plate, which are arranged in sequence. The upper end surface of the lower mold plate is provided with a molding cavity, the upper and lower end surfaces of the intermediate mold plate are both provided with molding cavities, and the lower end surface of the upper mold plate is provided with a molding cavity. Both sides of the intermediate mold plate are rotatably connected with lifting connectors, so that the intermediate mold plate can be flipped in a vertical direction. Through this design, products can be molded simultaneously between the lower mold plate and the intermediate mold plate, and between the intermediate mold plate and the upper mold plate, thereby increasing the number of products to be molded. At the same time, the intermediate mold plate can be flipped in a vertical direction, with the product molding surface facing the operator, facilitating demoulding of the product thereon.

[0009] The preferred technical solution: A rotating shaft and limiting rods are installed on both sides of the center template; the lifting connector is equipped with a lifting and positioning rod assembly, a rotating shaft mounting hole, a limiting rod slide, and a limiting rod locking mechanism. The lifting and positioning rod assembly is located outside the lifting connector and is used to connect to the external machine lifting mechanism. The rotating shaft is rotatably connected to the rotating shaft mounting hole, allowing the center template to rotate about the rotating shaft. The movement path of the limiting rod passes through the limiting rod slide. The limiting rod locking mechanism is removably installed on one side of the limiting rod slide to lock the limiting rod in the limiting rod slide.

[0010] Optimal technical solution: A limit slot is provided on the side of the limit rod slide, and a limit fork is provided at the front end of the limit rod locking mechanism. The limit fork can pass through the limit slot to clamp the limit rod in the limit rod slide, which is easy to operate.

[0011] Optimal technical solution: The front end of the limit fork is provided with a rounded corner structure, and the rear end of the limit rod locking mechanism is provided with an insertion and removal handrail, which reduces the difficulty of inserting and removing the limit fork in the limit slot.

[0012] Preferred technical solution: A lifting connector is provided on the top of the upper template for connecting to the lifting mechanism of an external machine.

[0013] Preferred technical solution: A guide column is provided on the lower template, and guide holes corresponding to the guide column are provided on the middle template and the upper template to improve the mold closing positioning accuracy.

[0014] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] The utility model relates to a vulcanizing mold with double-sided mold opening, which adopts the design of the middle template with double-sided mold opening, thereby increasing the number of products molded in a single time; turning mechanisms are added on both sides of the middle template, and the direction of the mold surface on the middle template can be adjusted after the mold is opened, which facilitates the demoulding of the molded products and the cleaning of the mold surface.

[0030] Example 1:

[0031] like Figure 1 and Figure 2 As shown, a double-sided vulcanization mold disclosed in the present invention includes a lower mold plate 1, an intermediate mold plate 2, and an upper mold plate 3 arranged in sequence. Both sides of the intermediate mold plate 2 are rotatably connected to a lifting connection member 4. The main components of the above-mentioned utility model will be described in detail below:
