Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold feeding devices, in particular to a mold feeding device. Background Art
[0002] Plastic tableware is usually mass-produced using injection molding technology through injection molds. Among them, the feeding operation is a very important link in the mold injection process. Its main function is to transport the heated and molten plastic material into the mold cavity.
[0003] The existing feeding device only provides a channel for the flow of hot-melt plastic. After the hot-melt plastic is transported, the feed port cannot be blocked, so that there is still hot-melt plastic remaining in the feed port in the feeding device channel. As the hot-melt plastic remaining at the edge of the feed port gradually increases and partially solidifies, it will affect the shape and size of the hot-melt plastic flowing out of the feed port, causing the rate at which the hot-melt plastic flows out of the feed port to decrease. The hot-melt plastic raw material contains part of the material solidified in the feed port, thereby reducing the quality of the plastic tableware and increasing the scrap rate of the product. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a mold feeding device.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a mold feeding device, comprising two fixed blocks, a connecting block is arranged between the two fixed blocks, a mounting block is installed on the side of the connecting block, a feed port is arranged obliquely at the bottom end of the mounting block, an oblique opening corresponding to the position of the feed port and connected to the side of the connecting block, a baffle plate is matched and inserted between the oblique opening and the feed port, a plurality of feed holes are arranged on the top of the mounting block, the plurality of feed holes are connected to the feed port, and a hydraulic telescopic cylinder is connected to one end of the baffle plate.

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0020] like Figure 1-6A mold feeding device shown includes two fixed blocks 7, a connecting block 11 is arranged between the two fixed blocks 7, and the two fixed blocks 7 and the connecting block 11 are an integrally formed structure, which improves the stability of the connection between the two fixed blocks 7 and the connecting block 11.
[0021] The side of the connecting block 11 is provided with a mounting block 6, and the mounting block 6 and the connecting block 11 are fixed by screws. When the mounting block 6 is maintained or replaced, it is only necessary to remove the screws, which facilitates the subsequent maintenance and replacement operations.
[0022] The bottom end of the mounting block 6 is provided with an inclined feed port 5 , which corresponds to a feed position of a mold cavity in a mold of the plastic tableware.
[0023] The side of the connection block 11 is provided with an oblique opening 10 corresponding to and connected to the feed port 5 . The oblique opening 10 allows the baffle plate 3 to slide in the connection block 11 and prevents the baffle plate 3 from moving and deviating, thereby playing a role of limiting.
[0024] A baffle plate 3 is matched and inserted between the oblique mouth 10 and the feed port 5, and a plurality of feed holes 4 are opened on the top of the mounting block 6, and the plurality of feed holes 4 are connected with the feed port 5. One end of the baffle plate 3 is connected with a hydraulic telescopic cylinder 2. After the hot-melt plastic is poured into the mold cavity, the baffle plate 3 is controlled to slide in the feed port 5 by the hydraulic telescopic cylinder 2. After the side of the baffle plate 3 is moved to the edge position of the feed port 5, the baffle plate 3 has a blocking effect on the plurality of feed holes 4 to prevent the hot-melt plastic in the feed hole from remaining on the edge of the feed port. Before the hot-melt plastic is poured into the mold cavity, the movable end of the hydraulic telescopic cylinder 2 needs to be controlled to contract. At this time, the hydraulic telescopic cylinder 2 drives the baffle plate 3 to move to one side of the feed hole 4, so that the feed hole 4 and the feed port 5 are connected, which facilitates the injection molding of the hot-melt plastic into the mold cavity.
[0025] A mounting seat 1 is installed at the fixed end of the hydraulic telescopic cylinder 2, and one end of a connecting column 8 is installed at both ends of the mounting seat 1. The other ends of the two connecting columns 8 are respectively installed on the surface of the fixed block 7. The mounting seat 1 and the two connecting columns 8 are used to fix the position of the hydraulic telescopic cylinder 2.
[0026] An oil inlet channel 12 and an oil outlet channel 9 are respectively provided at the ends of the mounting base 1. The oil inlet channel 12 and the oil outlet channel 9 are respectively connected to the oil inlet hole and the oil outlet hole of the hydraulic telescopic cylinder 2. The oil inlet channel 12 is connected to the oil pump through a hose, and the oil pump is connected to the oil storage tank through a hose, so that the hydraulic oil in the oil storage tank is conveniently transported to the oil inlet channel 12 through the hose by the oil pump, and the hydraulic oil in the oil inlet channel 12 is transported to the hydraulic telescopic cylinder 2 through the oil inlet hole; the oil outlet channel 9 is connected to the oil storage tank through a hose, so that the hydraulic oil in the hydraulic telescopic cylinder 2 is conveniently transported to the oil storage tank through the hose, thereby facilitating the control of the operation of the hydraulic telescopic cylinder 2.
[0027] The two symmetrical sides of the baffle plate 3 are both installed with limit blocks 16, and a fixing rod 13 is installed through the limit block 16. One end of the fixing rod 13 is installed on the connecting block 11, and a baffle 15 is installed on the other end of the fixing rod 13. A spring 14 is sleeved on the surface of the fixing rod 13, and the two ends of the spring 14 are respectively connected to the limit block 16 and the baffle 15.
[0028] Before the hot-melt plastic is injected, the movable end of the hydraulic telescopic cylinder 2 is controlled to retract, so that the movable end of the hydraulic telescopic cylinder 2 pulls the baffle plate 3 to slide in the feed port 5 toward the hydraulic telescopic cylinder 2, and the baffle plate 3 drives the two limit blocks 16 to slide synchronously along the fixed rod 13. The limit block 16 squeezes the spring 14 at this time. After the length of the spring 14 is contracted, the rebound force generated by the spring 14 acts on the baffle plate 3; on the contrary, when the hydraulic telescopic cylinder 2 drives the baffle plate 3 to insert into the feed port 5, the spring 14 is stretched, and the rebound force generated by it also acts on the baffle plate 3. The setting of the spring 14 can slow down the moving speed of the baffle plate 3, thereby reducing the wear between the baffle plate 3 and the feed port 5; during the sliding process of the fixed rod 13 in the limit block 16, it guides the movement of the baffle plate 3.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
