[0001] The utility model belongs to the extrusion die technical field, specifically relates to a PE wood plastic high -speed extrusion die. BACKGROUND

[0002] In today's plastic product production field, especially in the manufacturing process of PE wood plastic products, the extrusion die as the key production tool, its performance and function directly affect the quality and production efficiency of product, along with the market demand diversification and individualization, the specification size of PE wood plastic product presents the trend of diversification. The traditional PE wood plastic extrusion die usually has fixed size and structure, this exposes obvious limitation when coping with changeable market demand.

[0003] In the past production practice, when the enterprise receives the order of different length and width specification PE wood plastic product, due to the fixedness of die size, the enterprise has to reserve a large number of different size specification extrusion dies. These dies not only occupy the valuable production space, but also bring heavy burden in procurement, storage and management.

[0004] From the procurement point of view, the purchase of multiple size dies needs to invest a large amount of funds, increases the production cost of enterprise. Moreover, along with the increase of die quantity, the difficulty of quality monitoring and maintenance also increases, once the quality problem of certain die appears, can cause the delay of entire production link.

[0005] In the production process, replacing the die is a complex and time -consuming work. Each time replacing the die needs to stop the production line, disassembles the original die, and installs the new die, then carries out debugging and calibration to ensure the size precision and quality of product. This process not only consumes a large amount of time, reduces the production efficiency, and the frequent die disassembly also can cause damage to the die itself, shortens its service life.

[0006] In addition, due to the difference of different size dies in design and manufacture, the operating personnel needs to be familiar with and master the die characteristics of multiple specifications in the use and maintenance process, which puts forward higher requirements to the skills and experience of operating personnel.

DETAILED DESCRIPTION

[0025] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically explained below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0026] As Figures 1-5 shown, the technical scheme adopted by the utility model is specifically as follows: a PE wood plastic high-speed extrusion die, comprising a die body 1, the die body 1 includes four L-shaped templates 2, every two L-shaped templates 2 are provided with a through groove 3 on the side close to each other, and a stretching assembly is arranged on the inner wall of every through groove 3, a connecting plate 4 is arranged between the two stretching assemblies, the top and bottom of the connecting plate 4 are provided with a first mounting groove 5 and a second mounting groove 6, the first mounting groove 5 and the second mounting groove 6 are communicated, a elastic compensation assembly is arranged in the first mounting groove 5, and a compensation block 7 connected with the elastic compensation assembly is arranged in the second mounting groove 6.

[0027] The working principle is that the forming groove on the mold body 1 is connected with the extruder outside, ready to receive the extruded melted PE wood plastic, the extruder starts to work, the melted PE wood plastic is extruded into the forming groove of the mold body 1, and the preliminary forming is carried out according to the shape of the mold. When different lengths of products need to be produced, the connecting plate 4 is kept stationary, and the left and right two L-shaped templates are manually moved to the left and right sides respectively. In the process of moving the L-shaped template, the stretching assembly in the through slot 3 also moves. With the movement of the stretching assembly, the elastic compensation assembly originally located in the through slot 3 is gradually pulled out of the through slot 3. After the elastic compensation assembly is pulled out of the through slot 3, it restores elasticity and stretches to a certain length. The elastic compensation assembly after stretching makes the distance between the two compensation blocks 7 the same as the width of the L-shaped template after moving, so as to realize the length adjustment. When the required length is reached, the stretching assembly works, and the left and right two L-shaped templates are fixed at the current position due to the blocking of the compensation blocks 7, and the length adjustment is completed. When different widths of products need to be produced, the connecting plate 4 is kept stationary, and the upper and lower two L-shaped templates are manually moved upward and downward respectively. This movement makes the stretching assembly and the elastic compensation assembly in the through slot 3 produce corresponding actions again. The elastic compensation assembly is stretched out of the through slot 3 and restores elasticity. The stretching of the elastic compensation assembly makes the distance between the two compensation blocks 7 match the width of the L-shaped template after moving, so as to realize the width adjustment. When the required width is reached, the stretching assembly works, and the upper and lower two L-shaped templates are fixed at the current position due to the blocking of the compensation blocks 7, and the width adjustment is completed. Through the synergistic effect of the above steps, the device can flexibly adjust the size according to the production requirements without changing the mold, meet the production requirements of different specifications of products, and reduce the production cost of enterprises.

[0028] The width of the through slot 3 is the same as the width of the connecting plate 4. This arrangement can make the connecting plate 4 be received and stretched out in the through slot 3.

[0029] At the same time, the width of the connecting plate 4 plus the width of the two compensation blocks 7 is the same as the width of the L-shaped template 2. This arrangement can make the compensation blocks 7 parallel to the inner wall or the outside of the L-shaped template 2 when the compensation blocks 7 are stretched out, so that there is no protrusion or recess in the forming groove of the mold body 1. This arrangement can improve the accuracy of the mold.

[0030] The stretching assembly includes a first hollow shell 8 arranged on the inner wall of the through slot 3. A plurality of first springs 9 are arranged in the first hollow shell 8. One side of the first spring 9 is provided with a first piston plate 10. One side of the first piston plate 10 is provided with a first movable plate 11. The end of the first movable plate 11 away from the first piston plate 10 penetrates out of the first hollow shell 8 and is connected with the connecting plate 4.

[0031] When adjusting the width and length, the L-shaped template 2 moves, and when the L-shaped template 2 moves, it drives the first hollow shell 8 to move. When the first hollow shell 8 moves, it drives the first movable plate 11 to make the first piston plate 10 stretch the first spring 9, thereby adjusting the width and length.

[0032] like Figure 5 As shown, the elastic compensation assembly includes a second hollow shell 12 arranged inside the second mounting groove 6, a plurality of second springs 13 are arranged inside the second hollow shell 12, a second piston plate 14 is arranged on one side of the second spring 13, a second movable plate 15 is arranged on one side of the second piston plate 14, and the end of the second movable plate 15 away from the second piston plate 14 passes through the second hollow shell 12 and is connected to the compensation block 7.

[0033] When the compensation block 7 is pulled out from the through groove 3, the elastic force of the second spring 13 (the second spring 13 is in a compressed state) causes the second piston plate 14 to drive the first movable plate 11 to move the compensation block 7, thereby extending the compensation block 7 from the first mounting groove 5, so that the compensation block 7 is flush with the L-shaped mold, thereby forming a molding cavity for work.

[0034] It should be noted that the first spring 9 and the second spring 13 of the present invention are both specially customized, for example, special springs, special compression springs have a lifespan of between 10 million and 1 billion times; special tension springs have a lifespan of about 2 million times; therefore, the first spring 9 and the second spring 13 of the present invention can be applied.

[0035] At the same time, the distance moved by the compensation block 7 of the present invention is the elongation or compression of the second spring 13, that is, according to Hooke's law, we can obtain the elongation or compression of the spring. Through Hooke's law, we can choose a suitable spring for use according to the distance moved by the compensation block 7.

[0036] The selection of springs belongs to the prior art and will not be described in detail here.

[0037] The compensation block 7 is provided with a smooth surface, which not only enables the compensation block 7 to be easily withdrawn from the through groove 3, but also does not damage the formed wood sculpture.

[0038] In order to prevent the stretching assembly, the elastic compensation assembly and the compensation block 7 from being affected by the outside world, a cover plate (not shown in the figure) can be provided for sealing, and the cover plate is fixed by bolts.

[0039] The utility model discloses a working principle is as follows: the forming groove on the mould body 1 is connected with the extruder outside, prepares to receive the extrusion melt PE wood plastic, and the extruder starts work, and the melt PE wood plastic is extruded to the forming groove inside mould body 1, and it is preliminary formed according to the shape of mould. When the product of different length is needed to produce, keep the connecting plate 4 unmoved, and manually make the left and right two L-shaped templates move to the left and right sides respectively, in the process of L-shaped template movement, the stretching assembly in through groove 3 also moves along with it, along with the movement of stretching assembly, the elasticity compensation assembly originally located in through groove 3 is gradually pulled out from through groove 3, and the elasticity compensation assembly restores elasticity after being pulled out through groove 3, and stretches to a certain length, and the elasticity compensation assembly after stretching makes the distance between two compensation blocks 7 same with the width of L-shaped template after moving, thereby realizing the length direction adjustment, when reaching the length required, the stretching assembly plays a role, and the left and right two L-shaped templates are fixed in the current position due to the obstruction of compensation block 7, and the length adjustment is completed, when the product of different width is needed to produce, still keep the connecting plate 4 unmoved, and manually make the upper and lower two L-shaped templates move to the upper and lower sides respectively, and the movement makes the stretching assembly and elasticity compensation assembly in through groove 3 produce corresponding action again, and the elasticity compensation assembly stretches out from through groove 3 and restores elasticity, and the stretching of elasticity compensation assembly makes the distance between two compensation blocks 7 match with the width of L-shaped template after moving, thereby realizing the width direction adjustment, when reaching the width required, the stretching assembly plays a role, and the upper and lower two L-shaped templates are fixed in the current position due to the obstruction of compensation block 7, and the width adjustment is completed, through the synergistic effect of above steps, the device can flexibly adjust the size according to the production demand without changing mould, satisfies the production requirement of different specifications product, and reduces the production cost of enterprise.

[0040] The above only is the preferred implementation of the utility model, should point out, for the ordinary skill in the art, on the premise of not departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be regarded as the protection range of the utility model. The structure, device and operation method not specifically described and explained in the utility model, are implemented according to the conventional means of the field, if no special description and limitation.
