Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to extrusion dies for wood-plastic surface co-extruded elastomers. Background Technology

[0002] Extrusion dies are key components in the extrusion molding process. They are used to guide thermoplastic materials such as plastics and rubber through a specific shaped channel in the die, forming a continuous profile with a fixed cross-sectional shape, by heating, melting, and extruding them. Extrusion dies are widely used in the production of plastic products such as pipes, sheets, films, and profiles. They are also used in the production of wood-plastic co-extrusion elastomers.

[0003] Existing extrusion molds for wood-plastic composite surface co-extruded elastomers use bolts for connection during installation. However, during installation, workers need to align the bolt holes before installing the bolts, which results in low efficiency and is quite troublesome for workers. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an extrusion die for wood-plastic surface co-extruded elastomers to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an extrusion die for a wood-plastic surface co-extruded elastomer, including an extrusion die body. One side of the extrusion die body has an outlet for the wood-plastic surface co-extruded elastomer. The surface of the extrusion die body has a mounting hole. One side of the extrusion die body has an installation groove, which is coaxial with the mounting hole. A hollow connecting seat is fixedly installed on the inner wall of the installation groove. A sliding groove is formed on one side of the hollow connecting seat. A spring is fixedly installed on the inner wall of the sliding groove. A positioning block is fixedly installed at one end of the spring. The mounting base for the extrusion die body has a positioning hole on one side that matches the positioning block. The technical effect achieved by the above solution is that by attaching the side of the extrusion die body with the hollow connecting seat to the side of the mounting base, and then rotating the extrusion die body, when the positioning block on the side of the extrusion die body aligns with the positioning hole on the side of the mounting base, the positioning block enters the positioning hole on the side of the mounting base under the spring's rebound, thereby aligning the mounting hole of the extrusion die body with the mounting hole on the side of the mounting base. This makes the installation faster for the workers and greatly improves the installation efficiency.

[0007] Preferably, the inner wall of the mounting groove is provided with an internal thread, and the surface of the hollow connecting seat is provided with an external thread that matches the internal thread. The technical effect achieved by adopting the above solution is that, through the cooperation between the hollow connecting seat, the groove, the internal thread and the external thread, the hollow connecting seat can be easily disassembled from one side of the extrusion die body, which facilitates subsequent installation and replacement operations.

[0008] Preferably, in any of the above solutions, a groove is provided on the side of the hollow connecting seat away from the extrusion die body, and the length of the groove is less than the length of the hollow connecting seat. A ball bearing is rotatably connected to the inner wall of the groove, and the surface of the ball bearing is in contact with the surface of the positioning block. The technical effect achieved by the above solution is that the ball bearing can reduce the friction between the positioning block and the groove when the positioning block moves, thereby enabling the positioning block to enter the positioning hole on one side of the mounting seat more quickly.

[0009] Preferably, in any of the above solutions, the number of the balls is several, and the balls are circumferentially distributed on the inner walls of both sides of the groove. The technical effect achieved by the above solution is that the balls can reduce the friction between the positioning block and the groove when the positioning block moves, thereby enabling the positioning block to enter the positioning hole on one side of the mounting base more quickly.

[0010] Preferably, in any of the above solutions, a limiting groove is formed on the inner wall of the groove, the length of the limiting groove is less than the length of the groove, and a limiting slider located inside the limiting groove is fixedly connected to the surface of the positioning block. The technical effect achieved by the above solution is that the movement distance of the positioning block can be limited by the cooperation between the limiting groove and the limiting slider, thereby preventing the positioning block from detaching from the inside of the groove.

[0011] Preferably, all three sides of the limiting slider are provided with auxiliary balls, the surfaces of which are tangent to the inner wall of the limiting groove. The technical effect achieved by the above solution is that the auxiliary balls reduce friction when the limiting slider slides inside the limiting groove, thereby making the positioning block move faster.

[0012] Preferably, the surface of the positioning block is provided with two cut surfaces, which are symmetrically distributed on the surface of the positioning block. The technical effect achieved by adopting the above solution is that the cut surfaces make it easier for workers to hold the positioning block and rotate it when disassembling the hollow connecting seat, thereby making it easier to disassemble the hollow connecting seat.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. The extrusion die for the wood-plastic surface co-extruded elastomer, through the cooperation between the extrusion die body, mounting groove, hollow connecting seat, slide, spring, positioning block and positioning hole, enables the operator to quickly align the mounting hole of the extrusion die body with the mounting hole on the mounting seat when installing the extrusion die body, thereby making the installation faster and greatly improving the installation efficiency.

[0015] 2. The extrusion die for the wood-plastic surface co-extruded elastomer allows the hollow connecting seat to be easily disassembled from one side of the extrusion die body through the cooperation between the hollow connecting seat, the slide, the internal thread and the external thread, which facilitates subsequent installation and replacement operations.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] Example 1: As Figures 1 to 7As shown, the extrusion die for wood-plastic surface co-extruded elastomer includes an extrusion die body 1. One side of the extrusion die body 1 has an outlet for the wood-plastic surface co-extruded elastomer. The surface of the extrusion die body 1 has mounting holes 9. One side of the extrusion die body 1 has an installation groove 2, which is coaxial with the mounting holes 9. A hollow connecting seat 3 is fixedly installed on the inner wall of the installation groove 2. A sliding groove 4 is opened on one side of the hollow connecting seat 3. A spring 5 is fixedly installed on the inner wall of the sliding groove 4. A positioning block 6 is fixedly installed at one end of the spring 5. One side of the mounting base of body 1 is provided with a positioning hole that matches the positioning block 6. By attaching the side of the extrusion die body 1 with the hollow connecting seat 3 to the side of the mounting base, and then rotating the extrusion die body 1, when the positioning block 6 on one side of the extrusion die body 1 is aligned with the positioning hole on the side of the mounting base, the positioning block 6 enters the positioning hole on the side of the mounting base under the rebound of the spring 5, thereby aligning the mounting hole 9 of the extrusion die body 1 with the mounting hole on the side of the mounting base. This makes the installation faster for the workers and greatly improves the installation efficiency.

[0026] As an optional technical solution of this utility model, the inner wall of the mounting groove 2 is provided with an internal thread 7, and the surface of the hollow connecting seat 3 is provided with an external thread 8 that matches the internal thread 7. Through the cooperation between the hollow connecting seat 3, the sliding groove 4, the internal thread 7 and the external thread 8, the hollow connecting seat 3 can be easily disassembled from one side of the extrusion die body 1, which facilitates subsequent installation and replacement operations.

[0027] As an optional technical solution of this utility model, a groove 10 is provided on the side of the hollow connecting seat 3 away from the extrusion mold body 1, and the length of the groove 10 is less than the length of the hollow connecting seat 3. A ball bearing 11 is rotatably connected to the inner wall of the groove 10, and the surface of the ball bearing 11 contacts the surface of the positioning block 6. The ball bearing 11 can reduce the friction between the positioning block 6 and the groove 10 when the positioning block 6 moves, so that the positioning block 6 can enter the positioning hole on the side of the mounting seat more quickly.

[0028] As an optional technical solution of this utility model, the number of balls 11 is several. The balls 11 are circumferentially distributed on the inner walls of both sides of the groove 10. The balls 11 can reduce the friction between the positioning block 6 and the groove 10 when the positioning block 6 moves, so that the positioning block 6 can enter the positioning hole on one side of the mounting base more quickly.

[0029] As an optional technical solution of this utility model, a limiting groove 12 is provided on the inner wall of the groove 10. The length of the limiting groove 12 is less than the length of the groove 10. A limiting slider 13 located inside the limiting groove 12 is fixedly connected to the surface of the positioning block 6. Through the cooperation between the limiting groove 12 and the limiting slider 13, the movement distance of the positioning block 6 can be limited, thereby preventing the positioning block 6 from detaching from the inside of the groove 10.

[0030] As an optional technical solution of this utility model, auxiliary balls 14 are provided on three sides of the limiting slider 13. The surface of the auxiliary balls 14 is tangent to the inner wall of the limiting groove 12. The auxiliary balls 14 reduce friction when the limiting slider 13 slides inside the limiting groove 12, thereby making the positioning block 6 move faster.

[0031] As an optional technical solution of this utility model, the surface of the positioning block 6 is provided with a cut surface 15. There are two cut surfaces 15, which are symmetrically distributed on the surface of the positioning block 6. Through the cut surfaces 15, it is convenient for the staff to hold the positioning block 6 and rotate it when disassembling the hollow connecting seat 3, so as to make it easier to disassemble the hollow connecting seat 3.

[0032] The extrusion die for co-extruded elastomers on wood-plastic surfaces works as follows: By attaching one side of the extrusion die body 1 with the hollow connecting seat 3 to one side of the mounting seat, and then rotating the extrusion die body 1, when the positioning block 6 on one side of the extrusion die body 1 aligns with the positioning hole on one side of the mounting seat, the positioning block 6 enters the positioning hole on one side of the mounting seat under the rebound of the spring 5, thereby aligning the mounting hole 9 of the extrusion die body 1 with the mounting hole on one side of the mounting seat. This allows workers to install more quickly and greatly improves installation efficiency.

[0033] In summary, the extrusion die for this wood-plastic co-extruded elastomer, through the cooperation between the extrusion die body 1, mounting groove 2, hollow connecting seat 3, slide 4, spring 5, positioning block 6, and positioning hole, enables the operator to quickly align the mounting hole 9 of the extrusion die body 1 with the mounting hole on the mounting seat during installation, thus making the installation faster and greatly improving installation efficiency. Furthermore, through the cooperation between the hollow connecting seat 3, slide 4, internal thread 7, and external thread 8, the hollow connecting seat 3 can be easily removed from one side of the extrusion die body 1, facilitating subsequent installation and replacement operations.

[0034] Example 2: Extrusion mold for wood-plastic surface co-extruded elastomer. In this example, a friction pad is fixedly installed on one side of the cut surface 15 based on the above example. The friction pad increases the friction between the finger and the operator, thereby making it more stable when the operator disassembles the hollow connecting seat 3.
