Description

Technical Field

[0001] The utility model relates to the technical field of mold oil cylinder equipment, in particular to a two-plate type injection molding machine mold locking oil cylinder connection structure. Background Art

[0002] With the rapid development of new energy vehicles and home appliance industries in recent years, polymer synthetic materials and plastics are being widely used. The market demand for medium and large plastic product molding machines is also increasing, and two-platen injection molding machines are becoming more and more popular. For plastic machines, the role of the coring column is to withstand the huge clamping force to ensure the mold is closed and avoid flashing of the product. Because the product manufacturing cycle is short and the clamping force is large, the coring column reciprocates over and over again, which can easily cause the coring column to break. When producing thin-walled products, the production cycle is even shorter, so the phenomenon of coring column breakage is more common, and it may even cause the template to break.

[0003] The clamping cylinders currently used generally adopt a clamping built-in cylinder structure. The existing clamping built-in cylinder structure has broken built-in electronic ruler probes and the induction magnetic ring falls off due to clamping movement. The quality is poor and the subsequent maintenance cost is too high. Therefore, we need to provide a two-plate injection molding machine clamping cylinder connection structure. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a two-plate injection molding machine clamping cylinder connection structure, including a coring column 1, a clamping piston 2 is installed on the surface of the coring column 1, a clamping cylinder sleeve 3 is installed on the surface of the clamping piston 2 and the coring column 1, a clamping electronic ruler connecting rod 4 is arranged at one end of the coring column 1, a clamping rear cover 5 is installed on the surface of the clamping electronic ruler connecting rod 4, and one side of the clamping rear cover 5 is connected to the clamping cylinder sleeve 3 by a first screw 6, and a mounting mechanism 7 for fixing the clamping electronic ruler connecting rod 4 is arranged on the surface of the clamping piston 2.

[0020] The mounting mechanism 7 includes a piston rod pressure plate 71 and a second screw 72. A piston rod pressure plate 71 for limiting the mold locking electronic ruler connecting rod 4 is provided on one side of the coring column 1, and the piston rod pressure plate is installed at one end of the coring column 1 through a plurality of second screws 72;

[0021] In this embodiment, the piston rod pressure plate 71 is installed on one side of the coring column 1 by a second screw 72, so as to install the locking electronic ruler connecting rod 4 between the piston rod pressure plate 71 and the coring column 1.

[0022] One end of the mold-locking electronic ruler connecting rod 4 passes through the surface of the mold-locking rear cover 5 and extends, and a first bearing belt 8 is installed between the mold-locking electronic ruler connecting rod 4 and the mold-locking rear cover 5, and first oil seals 9 are arranged on both sides of the first bearing belt 8, and two first oil seals 9 are installed between the mold-locking electronic ruler connecting rod 4 and the mold-locking rear cover 5;

[0023] Furthermore, the two first oil seals 9 are installed between the mold locking electronic ruler connecting rod 4 and the mold locking rear cover 5, effectively preventing the lubricating oil from leaking from the lubricating components, thereby preventing the lubricating oil from contaminating or damaging other components.

[0024] A dust seal 10 is installed between the mold locking electronic ruler connecting rod 4 and the mold locking rear cover 5, and the dust seal 10 is arranged at the end of the mold locking electronic ruler connecting rod 4 away from the coring column 1;

[0025] Specifically, a dust seal 10 is installed between the mold locking electronic ruler connecting rod 4 and the mold locking rear cover 5 to prevent medium leakage and external impurities from invading, and at the same time play a role in balancing pressure and cooling and lubricating.

[0026] A second oil seal 11 is installed between the mold locking piston 2 and the mold locking cylinder sleeve 3, and second bearing bands 12 are arranged on both sides of the second oil seal 11, and the two second bearing bands 12 are installed between the mold locking piston 2 and the mold locking cylinder sleeve 3;

[0027] It should be noted that a second bearing belt 12 is provided on both sides of the second oil seal 11.

The back pressure ring 16 applies a certain pressure to keep the rolling elements inside the bearing in a stable arrangement and clearance, thereby improving the rotation accuracy and stability of the bearing.

[0030] A circular purlin 15 is installed between the clamping cylinder sleeve 3, the clamping cover plate and the coring column 1;

[0031] It is worth noting that Yuanling 15 has the advantages of saving space, reducing leakage points, fast response, small leakage, durability and easy combination.

[0032] This device is based on the improvement of the clamping cylinder structure of the LK two-platen injection molding machine FA1600. The improved features are that it adopts a spherical contact structure, allows the axis deviation caused by the drooping of the column 1 due to gravity, and changes the electronic ruler of the clamping cylinder from built-in to external, which solves the problems of the built-in electronic ruler probe breaking and the induction magnetic ring falling off due to the clamping movement, reduces the subsequent maintenance cost, and improves the quality performance.
