Description

Technical Field

[0001] This utility model relates to the field of pipe forming technology, and in particular to a core demolding transmission structure for a bridge elbow mold. Background Technology

[0002] PPR pipes are widely used in industrial and residential buildings for domestic and international water supply, drinking water, and hot water heating. PPR pipes can be used for both cold and hot water, and are environmentally friendly and hygienic. They are currently the most commonly used water supply pipes in home decoration projects. PPR pipes are also called Type 3 polypropylene pipes. They were developed in the late 1980s using a gas-phase copolymerization process to randomly and uniformly polymerize about 5% PE in the molecular chain of PP (random copolymerization), thus becoming a new generation of pipe materials. PPR pipe fittings, such as bridging bends, are connecting fittings that need to cross over the top of the pipe during the pipe laying process. The fittings are arched.

[0003] Regarding the aforementioned technologies, the existing demolding transmission structure has the following drawback: when an arched product is ejected directly during demolding, the curved surface of the product will come into contact with and rub against the inner wall of the mold, causing damage to the mold core and the product. Therefore, this utility model provides a mold core demolding transmission structure for a bridge bend mold. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-4 The diagram illustrates a core demolding transmission structure for a bridge bend mold, comprising a mounting plate 1 and a motor 10. The output end of the motor 10 passes through the mounting plate 1, and a transmission assembly is provided at the output end of the motor 10. The transmission assembly includes a rotating rod 6 fixedly connected to the output end of the motor 10. A connecting rod 7 is fixedly connected to the end of the rotating rod 6 away from the motor 10, and a transmission rod 8 is fixedly connected to the end of the connecting rod 7 away from the rotating rod 6. The transmission rod 8 is arc-shaped to facilitate product removal. A fixing rod 2 is fixedly connected to the side of the mounting plate 1, and a [missing information - likely a component or component] is fixedly connected to the end of the fixing rod 2 away from the mounting plate 1.
