Description

Technical Field

[0001] The utility model relates to the technical field of plastic parts manufacturing, in particular to a compression molding device with a guide component. Background Art

[0002] Plastic parts are very common items in daily life, and compression molding is widely used in their manufacturing process. Compression molding is an important process in plastic manufacturing. It mainly uses pressure to shape the plastic raw materials into the desired shape. After cooling, plastic products with specific shapes and sizes can be obtained.

[0003] When producing plastic parts, the compression molding device can close the two molds through the guiding effect of the guide component to complete the compression molding of the plastic parts. However, during the compression molding process of the plastic parts, after the two molds are closed, if there is a lot of plastic raw materials between the two molds, the plastic raw materials will leak out from the gap between the two molds, causing scraps to appear at the edge of the plastic parts. The staff will then need to cut the scraps, which increases the labor and time cost. For this reason, we provide a compression molding device with a guide component. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] First embodiment

[0024] As attached Figure 1 To Attachment Figure 4 As shown: a compression molding device with a guide assembly, comprising a bottom plate 1, a bottom mold 2 is installed on the upper surface of the bottom plate 1, a cutting assembly 3 is arranged below the bottom plate 1, and a circular through groove 5 is opened on the upper surface of the bottom plate 1. The cutting assembly 3 includes an electric push rod 301 installed on the bottom surface of the bottom plate 1, a cross plate 302 is fixedly connected to the bottom end of the electric push rod 301, and a circularly arranged slide plate 303 is fixedly connected to the upper surface of the cross plate 302. The top ends of the two sets of slide plates 303 pass through the through groove 5. They are fixedly connected with a frame-shaped knife 304, the top of the frame-shaped knife 304 is close to the outside of the bottom mold 2 as a pointed end, the bottom end of the frame-shaped knife 304 has a certain thickness, the outer surface of each slide plate 303 is slidably connected to the inner wall of the through groove 5, the frame-shaped knife 304 is located outside the bottom mold 2, and the electric push rod 301 will drive the cross plate 302 to move when it shrinks, and the slide plate 303 will slide and rise on the inner wall of the through groove 5, and the frame-shaped knife 304 will complete the cutting of scraps during the rising process.

[0025] The outer surface of the frame-shaped knife 304 is fixedly connected to a guide frame 305, and the outer side of the guide frame 305 is inclined downward. When the frame-shaped knife 304 cuts off the scraps, the cut scraps will fall onto the guide frame 305 and will fall along the guide frame 305 to the outside of the bottom plate 1, making it convenient for the staff to pick up and process the cut scraps.

[0026] The outer surface of each slide plate 303 is fixedly connected to two limit blocks 306, and the two limit blocks 306 are respectively located above and below the bottom plate 1. When the electric push rod 301 rises, the limit block 306 located below the bottom plate 1 can limit the slide plate 303 from rising too long, thereby preventing the frame-shaped knife 304 from being squeezed and damaged. When the electric push rod 301 descends, the limit block 306 located above the bottom plate 1 can prevent the slide plate 303 from descending too long, thereby ensuring that the frame-shaped knife 304 is located outside the bottom mold 2.

[0027] Two top plates 307 are fixedly connected to the outer surface of each slide plate 303, and the top of each top plate 307 is connected to the bottom surface of the frame knife 304. The connection between the top plate 307, the slide plate 303 and the frame knife 304 can be used to stably support the frame knife 304, thereby ensuring the stability of the frame knife 304 during cutting.

[0028] Second embodiment

[0029] A guide pressing assembly 4 is installed on the upper surface of the base plate 1, and the guide pressing assembly 4 includes two sets of vertical plates 401 fixedly connected to the upper surface of the base plate 1, and the top ends of the two vertical plates 401 are commonly fixedly connected to a mounting plate 402, and a hydraulic push rod 403 is installed on the bottom surface of the mounting plate 402, and an upper mold 404 is installed on the bottom end of the hydraulic push rod 403. The upper mold 404 can be pushed down by the operation of the hydraulic push rod 403, so that the upper mold 404 and the bottom mold 2 can be closed to complete the compression molding of the plastic part.

[0030] A guide groove 405 is formed on the side of each group of vertical plates 401 that are close to each other, and the inner wall of each guide groove 405 is rollingly connected to a guide wheel 406. The outer surface of each guide wheel 406 is rotatably connected to a connecting plate 407 via a rotating shaft. The side of each group of connecting plates 407 that are close to each other are respectively connected to the left and right side surfaces of the upper mold 404. When the upper mold 404 descends, the connecting plate 407 will drive the guide wheel 406 to roll inside the guide groove 405, which can play a stable guiding role for the upper mold 404 and avoid jamming when guiding the upper mold 404.

[0031] Nine metal heat-conducting rods 408 are fixedly embedded on the inner wall of the upper mold 404. The nine metal heat-conducting rods 408 are arranged at equal distances. The metal heat-conducting rods 408 can be made of copper, aluminum or stainless steel. They can conduct the heat absorbed by the upper mold 404 to the outside, thereby reducing the temperature of the compression-molded plastic parts and allowing the plastic parts to be quickly cooled and formed.

[0032] Working principle: When in use, the plastic raw material can be poured onto the bottom mold 2, and then the hydraulic push rod 403 is started to work. The hydraulic push rod 403 will push the upper mold 404 to descend. When the upper mold 404 descends, it will drive the guide wheel 406 to roll inside the guide groove 405, which can ensure the smooth descent of the upper mold 404. When the upper mold 404 and the bottom mold 2 are closed, the compression molding of the plastic part will be completed, and then the electric push rod 301 will be started to shrink. The electric push rod 301 will drive the cross plate 302 to rise, and at the same time, the slide plate 303 will move up inside the through groove 5, and the frame knife 304 will rise, which can cut off the plastic raw material overflowing from the bottom mold 2, thereby reducing the labor and time cost of manual labor.
