Description

Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, specifically to an extrusion molding equipment. Background Technology

[0002] Plastic flowers are a common handicraft. In the production process of plastic flowers, extrusion molding is generally used to produce plastic petals. Finally, multiple plastic petals are fixed on the flower stem according to the corresponding assembly method to obtain the plastic flower product. Therefore, an extrusion molding equipment is required.

[0003] Existing extrusion molding equipment typically uses cylinders or hydraulic cylinders to push the upper die downwards to extrude plastic material on the worktable. However, since the plastic material is at a high temperature during extrusion molding, waste material tends to stick together after the upper die comes into contact with the material and is extruded, which affects the next use of the upper die. In view of this, we propose an extrusion molding equipment. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion molding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion molding equipment, including a worktable, a top plate fixedly connected to the upper surface of the worktable via a column, a cylinder fixedly installed on the upper surface of the top plate, a pressure plate fixedly connected to the output end of the cylinder through the top plate, an upper die fixedly installed on the lower surface of the pressure plate, and a cleaning assembly provided on the lower surface of the pressure plate, the cleaning assembly including:

[0006] A vertical plate is fixedly installed on the upper surface of the workbench. A guide rod is fixedly installed on the outer wall of the vertical plate near the center of the workbench. A cleaning plate is slidably installed on the lower surface of the pressure plate. A guide groove is provided on the side wall of the cleaning plate. A contact wheel is rotatably installed on the inner surface of the cleaning plate. A central rod is fixedly installed through the axis of the contact wheel. A bidirectional thread is provided on the arc-shaped outer wall of the central rod.

[0007] A brush plate is slidably mounted on the bottom inner surface of a cleaning plate. A through hole with a diameter larger than the outer diameter of the center rod is opened on the inner wall of the brush plate. A threaded sleeve is fixedly installed on the inner surface of the through hole. A connecting plate is fixedly installed on the lower surface of the pressure plate. A T-shaped plate is fixedly installed at the bottom end of the connecting plate. An air bladder is fixedly connected to the side wall of the T-shaped plate. An air blowing channel is opened on the inner wall of the brush plate.

[0008] Preferably, the number of upright plates is set to four, and the four sets of upright plates are evenly distributed in a rectangular array around the top center of the workbench, thereby making the movement of the cleaning plate more stable.

[0009] Preferably, the guide groove is set in an inclined shape with the side closer to the center of the pressure plate higher and the side farther away from the center of the pressure plate lower, and the inner diameter of the guide groove is adapted to the outer diameter of the guide rod, so that during the pressing of the pressure plate, the guide rod on the side of the upright plate enters the guide groove, thereby causing the cleaning plate to move along the lower surface of the pressure plate toward the side farther away from the center of the pressure plate.

[0010] Preferably, the airbag is provided with an elastic steel mesh inside, the lower surface of the cleaning plate is provided with a straight groove, and the part of the airbag in the straight groove is provided with a one-way air inlet. At the same time, the top of the airbag is provided with a one-way air outlet on the side close to the air blowing channel, and the airbag is connected to the bottom inner wall of the air blowing channel through the one-way air outlet.

[0011] Preferably, a connecting assembly is provided on the side of the cleaning plate near the center of the upper mold. The connecting assembly includes a slide rod, which is fixedly installed in the inner wall of the cleaning plate near the upper mold. A connecting rod is slidably installed through the outer wall of the slide rod. A movable cavity is opened in the inner wall of the cleaning plate. A fixing plate is fixedly installed in the inner wall of the movable cavity. A return spring is fixedly connected between the side wall of the fixing plate and the side wall of the connecting rod.

[0012] Preferably, the top of the connecting rod is provided with wire brush bristles, and the end of the connecting rod away from the cleaning plate is set in an arc shape to avoid the two sets of cleaning plates jamming together when they come close to each other.

[0013] Compared with the prior art, the present invention provides an extrusion molding equipment, which has the following beneficial effects:

[0014] 1. This extrusion molding equipment, equipped with a cleaning component, allows the pressure plate to move upwards under the control of a cylinder after extrusion molding. Driven by the guide rod and guide groove, and with the elastic steel mesh inside the airbag, the cleaning plate moves towards the center of the upper die. Driven by the contact wheel and with the bidirectional thread, the brush plate moves along the inner surface of the cleaning plate towards the center of the upper die while simultaneously making a small reciprocating motion in the horizontal direction. This cleans the bottom surface of the upper die, preventing plastic residue from affecting the next extrusion molding operation.

[0015] 2. This extrusion molding equipment is equipped with a connecting component. When the two sets of cleaning plates approach each other, the arc-shaped surfaces of the corresponding connecting rod ends of the two sets of cleaning plates cause the connecting rods to move slightly in the horizontal direction when they approach each other. This improves the cleaning effect of the connecting rods in the bottom area of ​​the upper die and protects the upper die when the two sets of cleaning plates completely close the bottom of the upper die.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: an extrusion molding equipment, including a workbench 1, a top plate 2 fixedly connected to the upper surface of the workbench 1 by a column, a cylinder 3 fixedly installed on the upper surface of the top plate 2, a pressure plate 4 fixedly connected to the output end of the cylinder 3 through the top plate 2, an upper die 5 fixedly installed on the lower surface of the pressure plate 4, and a cleaning component 6 provided on the lower surface of the pressure plate 4. The cleaning component 6 includes a vertical plate 61, a guide rod 62, a cleaning plate 63, a guide groove 64, a contact wheel 65, a center rod 66, a bidirectional thread 67, a brush plate 69, a threaded sleeve 68, a connecting plate 610, a T-shaped plate 611, an airbag 612, and an air blowing channel 613.

[0024] In one embodiment of this utility model, a vertical plate 61 is fixedly installed on the upper surface of a workbench 1. A guide rod 62 is fixedly installed on the outer wall of the vertical plate 61 near the center of the workbench 1. A cleaning plate 63 is slidably installed on the lower surface of a pressure plate 4. A guide groove 64 is provided on the side wall of the cleaning plate 63. A contact wheel 65 is rotatably installed on the inner surface of the cleaning plate 63. A central rod 66 is fixedly installed through the axis of the contact wheel 65. A bidirectional thread 67 is provided on the arc-shaped outer wall of the central rod 66. A brush plate 69 is slidably installed on the bottom inner surface of the cleaning plate 63. A through hole with a diameter larger than the outer diameter of the central rod 66 is provided on the inner wall of the brush plate 69. A threaded sleeve 68 is fixedly installed on the inner surface of the through hole. A connecting plate 610 is fixedly installed on the lower surface of the pressure plate 4. A T-shaped plate 611 is fixedly installed at the bottom end of the connecting plate 610. An airbag 612 is fixedly connected to the side wall of the T-shaped plate 611. An air blowing channel 613 is provided on the inner wall of the brush plate 69.

[0025] Furthermore, the inner wall of the pressure plate 4 is provided with circular holes that match the columns, thereby guiding and restricting the movement of the pressure plate 4. A lower mold is located at the center of the worktable 1 to facilitate the placement of the plastic flower extrusion material within it. Specifically, when the cylinder 3 is activated, the vertical movement of the pressure plate 4 is more stable. Thus, when the pressure plate 4 drives the upper mold 5 downwards, it can extrude and shape the plastic flower extrusion material in the lower mold, ultimately obtaining the craft plastic flower product. In addition, four sets of vertical plates 61 are provided, and these four sets of vertical plates 61 are evenly distributed in a rectangular array around the top center of the worktable 1, thereby making the movement of the cleaning plate 63 more stable. Two sets of cleaning plates 63 are provided, and the two sets of cleaning plates 63 are symmetrically arranged with the vertical central axis of the pressure plate 4 as the axis of symmetry, so as to achieve the cleaning work on the bottom of the upper mold 5 on the left and right sides. Specifically, the guide groove 64 is set in an inclined shape with the side closer to the center of the pressure plate 4 being higher and the side farther away from the center of the pressure plate 4 being lower. The inner diameter of the guide groove 64 is adapted to the outer diameter of the guide rod 62, so that during the pressing of the pressure plate 4, the guide rod 62 on the side of the vertical plate 61 enters the guide groove 64, thereby causing the cleaning plate 63 to move along the lower surface of the pressure plate 4 toward the side farther away from the center of the pressure plate 4, until the lower surface of the upper mold 5 is completely exposed, so as to realize the extrusion molding of the plastic flower material at the bottom.

[0026] In addition, the central rod 66 is rotatably connected to the inner surface of the cleaning plate 63, and two sets of contact wheels 65 are provided, symmetrically arranged about the vertical central axis of the central rod 66. The top surface of the contact wheel 65 is in contact with the lower surface of the upper mold 5, so that the cleaning plate 63 can drive the contact wheel 65 to rotate as it slides along the lower surface of the upper mold 5. At the same time, several wire brushes are evenly arranged on the upper surface of the brush plate 69, so that the brush plate 69 can clean the upper mold 5 as it slides along the inner surface of the cleaning plate 63. The lower surface is cleaned. Furthermore, since the brush plate 69 is in contact with the inner surface of the cleaning plate 63, the movement of the brush plate 69 is restricted. Specifically, when the contact wheel 65 rotates, the brush plate 69 moves laterally back and forth along the inner wall of the cleaning plate 63 through the cooperation of the bidirectional thread 67 and the threaded sleeve 68. This improves the brushing and cleaning effect of the brush plate 69 on the bottom of the upper mold 5 when the relative movement occurs between the cleaning plate 63 and the upper mold 5, ensuring that no plastic residue appears on the lower surface of the upper mold 5, which would affect subsequent processing operations.

[0027] Meanwhile, the airbag 612 has an internal elastic steel mesh to ensure it tends to return to its original position during both expansion and compression. Additionally, the bottom inner wall of the cleaning plate 63 has a cavity for accommodating the airbag 612, and the lower surface of the cleaning plate 63 has a straight groove. The portion of the airbag 612 within the straight groove has a one-way air inlet, while the top of the airbag 612, near the air passage 613, has a one-way air outlet. The airbag 612 connects to the air passage 613 through the one-way air outlet. The bottom inner wall is connected through, so that when the airbag 612 is squeezed and stretched, it can only draw air from the bottom one-way air inlet and blow air into the air blowing channel 613 through the top one-way air outlet. Furthermore, the air blowing channel 613 includes a vertical opening and an arc-shaped cavity. There are two sets of arc-shaped cavities, and the two sets of arc-shaped cavities are mirror images of each other on the left and right sides of the top of the vertical opening. This improves the effect of the air blowing channel 613 on the air blowing auxiliary cleaning of the top space of the brush plate 69, thereby improving the device's cleaning ability on the lower surface of the upper mold 5.

[0028] In an embodiment of this utility model, a connecting component 7 is provided on the side of the cleaning plate 63 near the center of the upper mold 5. The connecting component 7 includes a slide rod 71, which is fixedly installed in the inner wall of the cleaning plate 63 near the upper mold 5. A connecting rod 72 is slidably installed through the outer wall of the slide rod 71. A movable cavity is opened in the inner wall of the cleaning plate 63, and a fixing plate 73 is fixedly installed in the inner wall of the movable cavity. A return spring 74 is fixedly connected between the side wall of the fixing plate 73 and the side wall of the connecting rod 72.

[0029] Specifically, the top of the connecting rod 72 is provided with wire brush bristles, and the end of the connecting rod 72 away from the cleaning plate 63 is set in an arc shape to avoid the two sets of cleaning plates 63 from jamming together when they approach each other. Through the compression of the arc-shaped surfaces of the corresponding ends of the connecting rod 72 of the two sets of cleaning plates 63, the connecting rod 72 will be slightly displaced in the horizontal direction when they approach each other, thereby improving the cleaning effect of the connecting rod 72 in the bottom area of ​​the upper mold 5, and protecting the upper mold 5 when the two sets of cleaning plates 63 completely close the bottom of the upper mold 5.

[0030] In this utility model, when in use, the plastic flower raw material is placed at the center of the upper surface of the workbench 1. At this time, the cylinder 3 is activated, and in conjunction with the pressure plate 4, the upper mold 5 is driven to move downward in the vertical direction, thereby realizing the extrusion molding of the plastic flower raw material on the workbench 1, and finally obtaining the plastic flower handicraft.

[0031] Furthermore, during the downward movement of the pressure plate 4, the guide rod 62 enters the interior of the guide groove 64. The inclined arrangement of the guide groove 64 causes the cleaning plate 63 to move away from the center of the upper mold 5 until it is fully exposed on the lower surface of the upper mold 5. After extrusion molding, the pressure plate 4 moves upward under the control of the cylinder 3. At this time, driven by the guide rod 62 and the guide groove 64, and with the elastic steel mesh inside the air bag 612, the cleaning plate 63 moves towards the center of the upper mold 5. Driven by the contact wheel 65 and with the bidirectional thread 67, the brush plate 69 moves towards the center of the upper mold 5 on the inner surface of the cleaning plate 63 while also making a small reciprocating motion in the horizontal direction, thereby cleaning the bottom surface of the upper mold 5 and preventing the residue of plastic raw materials from affecting the next extrusion molding operation.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
