Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine for processing plastic products. Background Art

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are available in vertical, horizontal, and all-electric models. They heat the plastic and apply high pressure to the molten plastic, ejecting it and filling the mold cavity.

[0003] The Chinese utility model patent with publication number CN215619533U in the prior art relates to an injection molding machine for processing plastic products, comprising a first support frame, a second support frame being provided on the right side of the first support frame, and a first template being fixedly connected to the right side of the upper end of the first support frame. In the utility model, when demoulding, the first hydraulic cylinder is activated to drive the second mold fixed to the second fixed frame to move to the right side. At this time, the plastic product is located on the protrusion. The first hydraulic cylinder is then activated to drive the blocking mechanism to move to the right side, so that the ejector pin can be pulled out of the through hole. Compressed gas is then introduced through the air inlet pipe. The compressed gas enters the annular body through the air inlet channel and then enters the counterbore. Since the right side of the counterbore is blocked by the piston, the compressed air will move to the left side and enter the interior of the through hole, so that the plastic product can be demoulded under the action of air pressure.

[0004] However, during the use of this type of injection molding machine, the injection molding machine needs to adjust the flow rate of plastic feeding, but this type of injection molding machine does not regulate it when feeding the plastic, which easily causes inaccurate precision in the process of feeding the plastic raw materials, resulting in waste of plastic raw materials. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an injection molding machine for processing plastic products, so as to solve the problem that during the use of the injection molding machine in the prior art, the injection molding machine needs to adjust the flow rate of plastic feeding, but this type of injection molding machine does not regulate the plastic when feeding it, which easily causes inaccurate precision in the process of feeding the plastic raw materials, resulting in waste of plastic raw materials.

[0006] The purpose and effect of the utility model, an injection molding machine for processing plastic products, are achieved by the following specific technical means: an injection molding machine for processing plastic products, comprising a main body, a hydraulic cylinder and an injection molding mechanism, the hydraulic cylinder being fixedly connected to the upper side of the main body, the injection molding mechanism being fixedly installed on the other upper side of the main body, a hydraulic rod being provided at the side output end of the hydraulic cylinder, templates being provided at the side ends of the hydraulic rod and the injection molding mechanism, a base being fixedly installed at the lower part of the main body, a discharge port being provided at the lower part of the template, a material guide pipe being fixedly connected to the upper side of the injection molding mechanism, a feed hopper being fixedly connected to the upper part of the material guide pipe, a threaded sleeve being provided at the lower part of the feed hopper, an opening being provided on the side wall of the threaded sleeve, and the material guide pipe being threadedly connected to the opening.

[0007] Preferably, the feed hopper is provided in two corresponding positions on the left and right.

[0008] Preferably, the material guiding tube is arranged in a Y shape.

[0009] Preferably, the openings are symmetrically arranged on the left and right corresponding to the feed hoppers.

[0010] Preferably, a material guide plate located in the material guide tube is rotatably connected to the inner wall of the threaded sleeve.

[0011] Preferably, the material guide plates are provided in two pieces on the left and right sides respectively.

[0012] Preferably, the guide plate is arranged in an inclined shape.

[0013] Preferably, a protrusion located on the side of the material guide plate is fixedly connected to the inner wall of the opening.

[0014] Beneficial effects:

[0015] 1. A guide plate located in the guide tube is connected by rotating on the inner wall of the threaded sleeve. The guide plates are correspondingly arranged on the left and right, and are arranged in an inclined shape. As the threaded sleeve drives the guide plate to rise and fall, the side wall of the guide plate will slide on the side of the protrusion. When the threaded sleeve drives the guide plate to move downward, the guide plate will gradually slide downward against the side of the protrusion. During the inclined descent of the guide plate, the guide plate will be blocked by the protrusion and swing to the side, so that the distance between the guide plates will be shortened, the internal diameter of the guide tube will be reduced, and then after the closing valve below is opened, the plastic will be blocked and diverted by the guide plate when it is discharged downward, and the flow rate of the plastic transmitted downward will be reduced, so that the discharge amount of the material can be adjusted to avoid blockage and improve the processing efficiency of the injection molding machine.

[0016] 2. The feed hopper is divided into two corresponding left and right feed hoppers, and the bottom of the left and right feed hoppers is fixedly connected with a Y-shaped material guide pipe for discharging materials, so that materials of different colors can be discharged from different feed hoppers. By adjusting the threaded sleeve at the bottom of the guide pipe, plastics of different colors can be mixed and used. By rotating the threaded sleeves at the bottom of the two feed hoppers to different height differences, the raw materials at the bottom of the feed hoppers can be mixed at different feeding speeds, thereby making the injection molding machine more efficient in processing and molding plastic molds of different colors, thereby improving the practicality of the injection molding machine.

DETAILED DESCRIPTION

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

[0023] As attached Figure 1 To the attached Figure 4As shown: An injection molding machine for processing plastic products, including a main body 1, a hydraulic cylinder 2 and an injection molding mechanism 3, the hydraulic cylinder 2 is fixedly connected to the upper side of the main body 1, and the injection molding mechanism 3 is fixedly installed on the other side above the main body 1, and a hydraulic rod is installed on the side output end of the hydraulic cylinder 2, and a template 201 is fixedly installed on the side end of the hydraulic rod and the side end of the injection molding mechanism 3, so that when the hydraulic cylinder 2 drives the hydraulic rod to move sideways, the hydraulic rod will push the side end template 201 sideways, so that the template 201 will be against the side wall of the side end template 201 of the injection molding mechanism 3, so that the templates 201 will be relative to each other They are closed to each other, so that the plastic will be transferred to the template 201 through the injection molding mechanism 3 for molding. When the injection molding mechanism 3 is used as an injection molding machine for processing plastic products, a heater is installed inside the injection molding mechanism 3, so that it can heat the plastic raw material into a molten state, and then the telescopic push rod set on the side of the injection molding mechanism 3 can transfer the molten plastic raw material to the template 201 (the telescopic push rod is driven by electric or hydraulic means), so that it can form a plastic product after cooling. Among them, the injection molding machine is an ENGEL1300T injection molding machine, ENGEL 1300T injection molding machine ENGEL injection molding machine.

[0024] The main body 1 is fixedly mounted with a base 101 at the bottom thereof, which supports and limits the main body 1 . Grooves are provided on the side walls between the templates 201 , and plastic is extruded and formed inside the grooves.

[0025] It should be understood that the above-mentioned fixed connection means that there can be no relative movement between the two. There are many ways of fixed connection. Here, bolts can be used for fixing, which makes the hydraulic cylinder 2 more convenient to disassemble and maintain in the later stage.

[0026] A discharge port 202 is provided below the template 201 , so that after the plastic product between the templates 201 is formed, the formed mold can be discharged from the discharge port 201 .

[0027] A material guide pipe 401 is fixedly connected to the upper side of the injection molding mechanism 3, and a feed hopper 4 is fixedly connected to the upper side of the material guide pipe 401. After the upper side of the feed hopper 4 is opened and the plastic raw material is loaded into the interior, the feed hopper 4 can transfer the raw material downward into the material guide pipe 401.

[0028] An opening 501 is provided on the side wall of the material guide tube 401 at the bottom of the feed hopper 4. A threaded sleeve 5 is threadedly connected to the side wall of the opening 501, so that the opening 501 will be closed by the threaded sleeve 5. A closing valve is installed below the opening 501, so that after the plastic is transferred to the inside of the injection molding mechanism 3, the closing valve can close the material guide tube 401. Example

[0029] As attached Figure 1 To the attached Figure 4As shown, the feed hoppers 4 are provided in two corresponding left and right positions, and the openings 501 are symmetrically provided in the left and right positions corresponding to the feed hoppers 4 , so that plastics of different colors can be loaded into different feed hoppers 4 .

[0030] Among them, the guide pipe 401 at the bottom of the feed hopper 4 is set in a Y shape, so that different feed hoppers 4 can transfer different plastics into the guide pipe 401. When the plastic in the feed hopper 4 is discharged, the lower guide pipe 401 is opened and closed by closing the valve, so that the plastics in different feed hoppers 4 will not be confused during the discharge process.

[0031] As attached Figure 1 To the attached Figure 4 As shown: the inner wall of the threaded sleeve 5 is rotatably connected to a guide plate 6 located in the guide tube 401, and the guide plates 6 are correspondingly arranged on the left and right. When the threaded sleeve 5 is rotated laterally of the opening 501, the threaded sleeve 5 will rise and fall laterally of the opening 501, so that the threaded sleeve 5 can drive the guide plate 6 to rise and fall in the guide tube 401.

[0032] As attached Figure 1 To the attached Figure 4 As shown: the guide plate 6 is arranged in an inclined shape, and a protrusion 601 located on the side of the guide plate 6 is fixedly connected to the inner wall of the opening 501, so that when the threaded sleeve 5 drives the guide plate 6 to rise and fall, the side wall of the guide plate 6 will slide on the side of the protrusion 601. When the threaded sleeve 5 drives the guide plate 6 to move upward, the guide plate 6 will gradually rise against the side of the protrusion 601 when moving upward, thereby expanding the distance between the guide plates 6 and the internal diameter of the guide tube 401. After the closed valve below is opened, the flow rate of plastic transmitted downward will increase. When the groove sleeve 5 drives the guide plate 6 to move downward, the guide plate 6 will gradually descend against the side of the protrusion 601. During the process of the guide plate 6 descending in an inclined shape, the guide plate 6 will be blocked by the protrusion 601 and swing to the side, so that the distance between the guide plates 6 will be shortened, and the internal diameter of the guide tube 401 will be reduced. Then, after the closing valve below is opened, the plastic will be blocked and diverted by the guide plate 6 when discharging downward, and the flow rate of the plastic transmitted downward will be reduced, so that the discharge amount of the material can be adjusted, avoiding blockage and improving the processing efficiency of the injection molding machine.

[0033] Working principle: The main body 1 is supported by the base 101, and the side hydraulic rod is driven by the hydraulic cylinder 2 to push the template 201 sideways, so that the template 201 will abut against the side of the side template 201 of the injection molding mechanism 3, thereby closing the left and right templates 201 to each other, and opening the top of the feed hopper 4 to allow the plastic raw materials to be loaded into different feed hoppers 4. After that, the feed hopper 4 can transmit the raw materials downward to the guide tube 401, and by rotating and lifting the threaded sleeve 5 on the side of the opening 501, the threaded sleeve 5 will drive the guide plate 6 to rise and fall in the guide tube 401, and the side wall of the guide plate 6 will slide on the side of the protrusion 601. When the threaded sleeve 5 drives the guide plate 6 to move upward, the guide plate 6 will abut against the side of the protrusion 601 when moving upward, and then gradually rise, thereby expanding the distance between the guide plates 6, and the internal diameter of the guide tube 401 will expand, so that after opening the lower closing valve, the flow rate of plastic transmitted downward will increase, and when the threaded sleeve 5 drives the guide plate 6 to move downward, the guide plate 6 will abut against the protrusion 601 gradually descends sideways, and during the process of the guide plate 6 descending in an inclined shape, the guide plate 6 will be blocked by the protrusion 601 and swing sideways, so that the distance between the guide plates 6 will be shortened, and the internal diameter of the guide tube 401 will be reduced. Then, after the closed valve at the bottom is opened, the plastic will be blocked and diverted by the guide plate 6 when discharging downward, and the flow rate of the plastic transmitted downward will be reduced. When the material is transmitted to the injection molding mechanism 3 below through the guide tube 401, the injection molding mechanism 3 will transmit the raw material to the templates 201 for extrusion molding. By adjusting the threaded sleeve 5 at the bottom of the guide tube 401, plastics of different colors can be mixed and used, and by rotating the threaded sleeves 5 at the bottom of the two feed hoppers 4 to different height differences, the raw materials at the bottom of the feed hoppers 4 can be mixed at different feeding speeds, thereby making the processing and molding of plastic molds of different colors more efficient. After the mold between the templates 201 is formed, the template 201 is opened to discharge the formed mold from the discharge port 202 below.
