[0002] When the existing product is produced as a multi-layer cylindrical tube bundle product, the preformed material embryo is mostly in the shape of a ring or a column. Because the thickness of the preformed embryo of this structure reaches 15mm, the flat direct compression mold is easy. Formation of air bubbles or poor venting, so improvement is urgently needed
After forming, the product has many poor exhaust and air bubbles, and the defective rate of the product is as high as 85%. 25 pieces are taken per mold, and there are 20-21pcs of poor exhaust and insufficient sulfur, and most of the products adhere to the core, which makes demoulding difficult and inefficient. Only 3 molds per hour

Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] see Figure 1 to Figure 3 , the embodiment of the present invention includes:
[0019] A die head used on an extruder comprises a first layer 1 and a second layer 2, and the first layer 1 and the second layer 2 are connected up and down. The first layer 1 is provided with an "e" shaped mouth 3, and the "e" shaped mouth 3 is arranged through the first layer. A passage 4 is arranged in the second layer 2, and the passage 4 communicates with the mouth 3 of the "e" design.
[0020] The shape of the mouth 3 of t...

Abstract
The present invention discloses an extruder mold head, which comprises a first layer and a second layer, wherein the first layer and the second layer are arranged in an upper-lower connection manner, the first layer is provided with an opening mold with the e-shaped design, the opening mold with the e-shaped design penetrates through the first layer, and a channel is arranged in the second layer and is communicated with the opening mold with the e-shaped design. With the technical scheme, with the opening mold with the e-shaped design, the mold reforming cost and the mold reforming period are substantially reduced, the mold closing gas discharge is easily achieved, phenomena such as gas clogging, adverse gas discharge, gas bubbles and other like can not occur, the possibility of the adsorption of the product on the mold is reduced, the mold is easily taking out, and the production efficiency is increased.
Description
technical field [0001] The invention relates to the field of rubber product production and molding technology, in particular to a die head used on an extruder. Background technique [0002] When the existing product is produced as a multi-layer cylindrical tube bundle product, the preformed material blank is mostly in the shape of a ring or a column. Because the thickness of the preformed blank of this structure reaches 15mm, the flat direct compression mold is very easy. Air bubbles are forming or poor venting, so urgently need improvement. After molding, the product has many poor exhaust and air bubbles, and the defective rate of the product is as high as 85%. 25 pieces are taken per mold. There are 20-21pcs of poor exhaust and insufficient sulfur, and most of the products adhere to the core, which makes demoulding difficult and inefficient. There are only 3 molds per hour. Contents of the invention [0003] The technical problem mainly solved by the present invention ...
