Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a frame for an electro-melting injection unit. Background Technology

[0002] The injection frame is one of the core components of the injection unit of an electromelting injection molding machine. It not only plays a role in connecting and bearing the weight of the whole machine, but also requires sufficient strength. Under the high pressure of injection, the frame itself is subjected to backward tension. If the deformation exceeds the required value, it will not only affect the rigidity and strength and reduce the service life, but also directly affect the injection accuracy and stability.

[0003] The key design considerations for the injection molding machine's injection unit frame are to fully consider its stress characteristics, save manufacturing materials as much as possible while meeting rigidity requirements, reduce the frame's own weight, and ensure that the frame structure is simple, easy to install and disassemble. A reasonable and aesthetically pleasing design will also be well-received by users and enhance the brand image.

[0004] The existing firing platform frame is characterized by high material consumption, large weight, complex structure, difficult processing, and easy deformation under long-term repeated stress.

[0005] Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this invention is to provide a simple, lightweight, rigid, reliable, low-cost, and highly practical frame for an electrofusion adhesive injection station, in order to overcome the shortcomings of the prior art.

[0007] A frame for an electro-melting adhesive injection station designed for this purpose is characterized by comprising a front panel and a rear panel, wherein the four corners of the front panel and the four corners of the rear panel are connected by connecting ribs to form a cuboid frame.

[0008] A mounting plate for mounting the injection cylinder is provided below the front panel and extends downwards. Support ribs are provided on the rear side of the mounting plate.

[0009] Unloading angles are provided on the left and right sides of the front panel.

[0010] The front panel has a first mounting hole in the center for mounting the material cylinder, and a first reinforcing rib and a second reinforcing rib are respectively provided on the upper and lower sides of the front panel.

[0011] The center of the rear panel has a second mounting hole for mounting the injection cylinder, and the upper and lower sides of the rear panel have a third reinforcing rib and a fourth reinforcing rib, respectively.

[0012] The mounting plate and the second reinforcing rib are connected by a support rib.

[0013] The connecting ribs are shaped like the number "7" and are evenly distributed on the cuboid frame.

[0014] An opening is formed between the front panel, the rear panel, and the connecting ribs to allow a hand to be inserted into the cuboid frame. The openings are located on the left and right sides of the cuboid frame, respectively.

[0015] The bottom of the front panel and the rear panel are respectively provided with limiting bosses for positioning and installing the slider.

[0016] The electro-melting glue injection station includes an injection station base, on which a linear guide is mounted. A slider is mounted on the bottom of a limiting boss, and the injection station frame is mounted on the linear guide of the injection station base by sliding back and forth via the slider.

[0017] The four corners of the front panel and the four corners of the rear panel of the firing platform frame of this utility model are connected by connecting ribs to form a cuboid frame. The geometric structure effectively distributes the load, reduces stress concentration, and improves the overall strength, making the firing platform frame less prone to deformation even under long-term repeated stress. In addition, the cuboid frame structure is simple and easy to process. Openings are formed between the front panel, the rear panel and the connecting ribs. The openings not only allow the operator's hands to enter the frame for operation, but also reduce the consumption of frame materials and reduce the weight of the firing platform frame itself.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-6The frame of the electro-melting glue injection station includes a front panel 1 and a rear panel 2. The four corners of the front panel 1 and the four corners of the rear panel 2 are connected by four connecting ribs 3 to form a cuboid frame a. The geometric structure effectively distributes the load, reduces stress concentration, improves the overall strength, provides good rigidity, resists deformation, maintains good stability, and has a simple structure, consumes less material, is easy to process, and has low manufacturing cost.

[0026] A mounting plate 17 for mounting the injection cylinder 18 is provided on the lower part of the front panel 1. A support rib 4 is provided on the rear side of the mounting plate 17. The support rib 4 distributes the load and enhances the load-bearing capacity of the mounting plate 17.

[0027] The front panel 1 has unloading angles 5 on its left and right sides respectively. The unloading angles 5 are used to eliminate stress concentration, reduce stress, and reduce the risk of casting cracking.

[0028] The front panel 1 has a first mounting hole 6 for mounting the material cylinder at its center. The front panel 1 has a first reinforcing rib 7 and a second reinforcing rib 8 on its upper and lower sides, respectively. The first reinforcing rib 7 and the second reinforcing rib 8 enable the front panel 1 to have a certain load-bearing capacity (to support the material cylinder), thereby reinforcing the frame structure and maintaining structural stability.

[0029] The rear panel 2 has a second mounting hole 9 in the center for mounting the injection cylinder 12. The upper and lower sides of the rear panel 2 are respectively provided with a third reinforcing rib 10 and a fourth reinforcing rib 11. The third reinforcing rib 10 and the fourth reinforcing rib 11 enable the rear panel 2 to have a certain load-bearing capacity (to support the injection cylinder 12), thereby reinforcing the frame structure and maintaining structural stability.

[0030] Mounting plate 17 and second reinforcing rib 8 are connected by support rib 4.

[0031] The connecting rib 3 is shaped like the number "7" and is evenly distributed on the cuboid frame a. Figure 6 As can be seen from the installation structure, during injection, the connecting rib 3 is subjected to a backward tensile force. The connecting rib 3 is designed in the shape of a "7", which can effectively reduce the swaying deformation in the left and right and up and down. Moreover, the four connecting ribs 3 are evenly distributed, which can disperse the tensile stress. The maximum tensile stress is less than 60MPa, which is about 8 to 9 times the material safety factor, far exceeding the commonly used 2 to 4 times safety factor. The tensile strength is improved, and the service life of the injection molding machine is extended.

[0032] A rectangular opening 13 is formed between the front panel 1, the rear panel 2 and the connecting rib 3 for the hand to be inserted into the cuboid frame a. The opening 13 is respectively set on the left and right sides of the cuboid frame a. Under the premise of meeting the rigidity requirements, the rectangular opening 13 on the left and right sides of the connecting rib 3 not only allows the staff to enter the frame for operation, but also reduces the consumption of frame materials.

[0033] The bottom of the front panel 1 and the rear panel 2 are respectively provided with limiting bosses 16 for positioning and installing sliders 15; the electromelting injection station is set on the injection molding machine, which includes an injection station base 19, a linear guide 20 is installed on the injection station base 19, the slider 15 is installed at the bottom of the limiting bosses 16, and the injection station frame is slidably set on the linear guide 20 of the injection station base 19 by the slider 15, so that the injection station frame can move back and forth on the injection station base 19.

[0034] A fixed mounting plate 21 for mounting the material cylinder is provided on the front side of the front panel 1, and an injection device 22 is provided on the electromelting injection stage, which is located inside the injection stage frame.
