Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a large die head non-adjustable mold. Background Art

[0002] A large die head is a key component used for extrusion molding in the plastic processing industry, which undertakes the function of guiding the plastic melt from the barrel of the extruder and evenly distributing it to the die orifice. The design and manufacture of the large die head are of great significance for ensuring the quality of plastic products, improving production efficiency and reducing costs.

[0003] The existing large die head non-adjustable molds are usually installed on the surface of the extrusion die core. The feeding head of the large die head non-adjustable mold is usually arranged on the side wall, resulting in uneven force flow of the material in the feeding inner cavity of the large die head non-adjustable mold during feeding. Therefore, when forming, the inner wall thickness of the product is likely to be different, and there is a lack of constant temperature control for the raw material, resulting in quality problems caused by uneven temperature of the raw material. For this reason, we propose a large die head non-adjustable mold to facilitate fixing both ends of the shaft during grinding and then rotating it to improve the working efficiency of shaft grinding.

[0006] By adopting the above technical solution, when installing the mold core, since a connection mechanism is installed on the shell wall of the inner cavity mold body, and the connection mechanism is composed of a feeding head, an inner cavity block, a mold core and a locking bolt. After connecting the feeding head and the inner cavity mold body through bolts, since an inner cavity block is formed on the inner wall of the feeding head, the inner wall of the feeding head is divided into cavities through the inner cavity block. After the locking bolt penetrates through the mold core and is threadedly connected to the inner cavity block, the fixing of the mold core is realized. When the raw material enters through the feeding head, since a cavity is formed between the pipe wall of the stepped pipe, the inner wall of the inner cavity mold body and the outer wall of the mold core, the raw material enters through the cavity between the feeding head and the inner cavity block and then forms a cavity between the pipe wall of the stepped pipe, the inner wall of the inner cavity mold body and the outer wall of the mold core to realize forming, so that the feeding pressure is uniform and the inner wall thickness of the forming pipe is the same.

[0007] Specifically, it further includes a heating mechanism, and the heating mechanism is installed at the inner wall of the inner cavity mold body.

[0008] By adopting the above technical solution, the raw materials in the inner cavity mold body can be evenly heated by the heating mechanism.

[0009] Specifically, the heating mechanism is composed of a stepped pipe, a temperature detection sensor, and a heating rod. The stepped pipe is embedded and connected to the inner wall of the inner cavity mold body through bolts. Several groups of heating rods for heating are embedded in the inner wall of the stepped pipe, and the temperature detection sensor for detecting temperature is embedded in the inner wall of the stepped pipe.

[0010] By adopting the above technical solution, when the extruded material is uniformly heated for the second time, since the heating mechanism is installed at the inner wall of the inner cavity mold body and the heating mechanism is composed of a stepped pipe, a temperature detection sensor, and a heating rod, after the stepped pipe is fixed in the inner cavity mold body through bolts, since several groups of heating rods are embedded and connected in the stepped pipe, the stepped pipe is heated by the heating rods, and when the raw materials pass through the stepped pipe, the raw materials are uniformly heated, and the temperature of the stepped pipe is detected by the temperature detection sensor to stably control the heating temperature of the raw materials.

[0011] Specifically, a convex pipe is installed on the outer wall of the inner cavity mold body through bolts.

[0012] By adopting the above technical solution, the stepped pipe can be conveniently connected and fixed for the second time through the convex pipe.

[0013] Specifically, the pipe wall of the convex pipe is connected to the pipe wall of the stepped pipe through a connecting bolt.

[0014] By adopting the above technical solution, the stepped pipe and the convex pipe can be conveniently connected through the connecting bolt.

[0015] Specifically, a cavity is formed between the pipe wall of the stepped pipe, the inner wall of the inner cavity mold body, and the outer wall of the mold core.

[0016] By adopting the above technical solution, cavity extrusion molding is realized by forming a cavity between the pipe wall of the stepped pipe, the inner wall of the inner cavity mold body, and the outer wall of the mold core.

A connection mechanism 2 is installed on the shell wall of the inner cavity mold body 1. The connection mechanism 2 is composed of a feed head 201, an inner cavity block 202, a mold core 203, and a locking bolt 204. The feed head 201 is installed on the outer wall of the inner cavity mold body 1 through bolts. An inner cavity block 202 is formed on the inner wall of the feed head 201. The mold core 203 is inserted and connected to the inner wall of the inner cavity mold body 1. The inner wall of the mold core 203 is connected to the block wall of the inner cavity block 202 through the locking bolt 204.

[0027] During use, when installing the mold core 203, since the connection mechanism 2 is installed on the shell wall of the inner cavity mold body 1 and the connection mechanism 2 is composed of the feed head 201, the inner cavity block 202, the mold core 203, and the locking bolt 204. After connecting the feed head 201 to the inner cavity mold body 1 through bolts, since the inner cavity block 202 is formed on the inner wall of the feed head 201, the inner wall of the feed head 201 is divided into cavities through the inner cavity block. After the locking bolt 204 passes through the mold core 203 and is threadedly connected to the inner cavity block 202, the fixation of the mold core 203 is realized. When the raw material enters through the feed head 201, since a cavity is formed between the pipe wall of the stepped pipe 501, the inner wall of the inner cavity mold body 1, and the outer wall of the mold core 203, the raw material enters through the cavity between the feed head 201 and the inner cavity block 202, and then forms a cavity between the pipe wall of the stepped pipe 501, the inner wall of the inner cavity mold body 1, and the outer wall of the mold core 203 to realize molding, so that the feeding pressure is uniform and the inner wall thickness of the formed pipe is the same.

[0028] As shown in Figure 3 It further includes a heating mechanism 5. The heating mechanism 5 is installed on the inner wall of the inner cavity mold body 1.

[0029] During use, the raw material in the inner cavity mold body 1 can be evenly heated through the heating mechanism 5.

[0030] As shown in Figure 3 The heating mechanism 5 is composed of a stepped pipe 501, a temperature detection sensor 502, and a heating rod 503. The stepped pipe 501 is embedded and connected to the inner wall of the inner cavity mold body 1 through bolts. A number of heating heating rods 503 are embedded in the pipe inner wall of the stepped pipe 501. A temperature detection sensor 502 for detecting temperature is embedded in the pipe inner wall of the stepped pipe 501.

After the stepped tube 501 is fixed in the inner cavity mold body by bolts, since several groups of heating rods 503 are embedded and connected in the stepped tube 501, the stepped tube 501 is heated by the heating rods 503. When the raw material passes through the stepped tube 501, the raw material is uniformly heated, and the temperature of the stepped tube 501 is detected by the temperature detection sensor 502 to stably control the heating temperature of the raw material.

[0032] As Figure 1 shown, a convex tube 3 is installed on the outer wall of the inner cavity mold body 1 by bolts.

After connecting the feeding head 201 to the inner cavity mold body 1 through a bolt, since the inner cavity block 202 is formed on the inner wall of the feeding head 201, the inner wall of the feeding head 201 is divided into cavities through the inner cavity block. After the locking bolt 204 passes through the mold core 203 and is threadedly connected to the inner cavity block 202, the fixing of the mold core 203 is realized. When the raw material enters through the feeding head 201, since a cavity is formed between the pipe wall of the stepped pipe 501, the inner wall of the inner cavity mold body 1 and the outer wall of the mold core 203, the raw material enters through the cavity between the feeding head 201 and the inner cavity block 202, and then a cavity is formed between the pipe wall of the stepped pipe 501, the inner wall of the inner cavity mold body 1 and the outer wall of the mold core 203 to realize molding. Thus, the feeding pressure is uniform, and the inner wall thickness of the formed pipe is the same. When the extruded material is uniformly heated for the second time, since the heating mechanism 5 is installed on the inner wall of the inner cavity mold body 1, the heating mechanism 5 is composed of a stepped pipe 501, a temperature detection sensor 502 and a heating rod 503. After the stepped pipe 501 is fixed in the inner cavity mold body through a bolt, since several groups of heating rods 503 are embedded and connected in the stepped pipe 501, the stepped pipe 501 is heated through the heating rods 503. When the raw material passes through the stepped pipe 501, uniform heating of the raw material is realized. The temperature of the stepped pipe 501 is detected through the temperature detection sensor 502 to realize stable temperature control of the heating temperature of the raw material.
