带阻流装置的管材机头

Pipe machine nose with choke device

Abstract

A pipe machine nose with a choke device comprises a compression plate, a nozzle mould, a nose body, a distributing bush, a distributor support, a distributor and an inner connector and is characterized in that the compression plate and the inner connector are connected to two ends of the nose body, a filter mesh plate is disposed at one end of the inner connector, a buffer mandrel is disposed at a center axis of the nose body. A choke mandrel is disposed at one end of the buffer mandrel, and the outer wall of the buffer mandrel, close to the end of the choke mandrel is provided with at least one circular groove. The outer wall of the choke mandrel is provided with at least one circular projection, and the other end of the chock mandrel is connected with the distributor. A cavity is formed between the nose body and the buffer mandrel, choke mandrel and distributor. The nozzle mould, the distributing bush and the distributor support are sequentially connected and are located in the cavity. Compared with the prior art, the pipe machine nose is provide with the buffer mandrel having the circular grooves, so that performance of plasticizing materials is improved and welding marks generated on the distributor support are eliminated.
一种带阻流装置的管材机头,包括压紧板、口模、机头体、分流套、分流器支架、分流器以及内层连接器,其特征在于机头体的两端连接有压紧板和内层连接器,内层连接器一端都设有过滤网板,机头体中心轴处设有缓冲芯棒,缓冲芯棒的一端设有阻流芯棒,且缓冲芯棒靠近阻流芯棒这端的外壁上设有至少一道环形凹槽,阻流芯棒外壁上设有至少为一道的环形凸台,其阻流芯棒另一端与分流器相连,缓冲芯棒、阻流芯棒和分流器与机头体之间形成一腔体,其口模、分流套以及分流器支架依次连接且位于上述腔体里。与现有技术相比,本实用新型采用设有环形凹槽的缓冲芯棒,提高了物料的塑化性能以及消除了分流器支架产生的熔接痕。
