It controls the temperature, pressure, speed and injection time of the plastic to fully fill the plastic into all parts of the mold, thereby obtaining high-precision and high-quality products. According to the injection pressure, it can be divided into large injection molding machines and small injection molding machines. Among them, large injection molding machines are suitable for the production of large plastic products, and small injection molding machines are suitable for the production of small plastic products. According to the structural type, it can be divided into different types such as horizontal injection molding machines, vertical injection molding machines and multi-unit linkage injection molding machines. The injection molding machine has the advantages of high productivity, high efficiency, high molding precision and stable product quality. It is widely used in the manufacture of various plastic products, such as toys, electronic products, auto parts, bottle caps, tableware, etc. During the operation of the operator, it is generally necessary to use the positioning component in advance to position the mold.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0024] A floating positioning assembly for injection molding equipment includes a cover plate 11, first card slots 13 are provided on both sides of the bottom of the cover plate 11, a first card block 2 is clamped inside the first card slot 13, and a base 1 is fixedly connected to the bottom of the first card block 2. Through the arrangement of the cover plate 11, the first card slot 13, the first card block 2 and the base 1, an operator can separate the first card block 2 from the first card slot 13 during use, thereby separating the cover plate 11 from the base 1, thereby achieving the effect of removing the positioning pin 14, avoiding the difficulty of disassembly and replacement when the positioning pin 14 is damaged or needs to be replaced during use, which is convenient for the operator. The replacement is time-consuming and laborious for the operators. A placement groove 3 is provided at the center of the top of the base 1. A pin sleeve 16 is clamped on the inner wall of the placement groove 3. A positioning pin 14 is slidably connected to the inner wall of the pin sleeve 16. Through the arrangement of the placement groove 3 and the pin sleeve 16, the placement groove 3 restricts the pin sleeve 16 so that it does not move. A connecting block 8 is slidably connected to the outer surface of the positioning pin 14. A sliding groove 9 is provided inside the connecting block 8. The inner wall of the sliding groove 9 is slidably connected to the first slide plate 4 and the second slide plate 6. Through the arrangement of the sliding groove 9, the first slide plate 4 and the second slide plate 6 can be moved inside the connecting block 8 when in use;

[0025] In this embodiment, preferably, a hole 12 is opened inside the cover plate 11, and a positioning pin 14 is slidably connected inside the hole 12. Through the setting of the hole 12, the positioning pin 14 can pass through the cover plate 11, so that the cover plate 11 does not hinder the upward and downward movement of the positioning pin 14;

[0026] In this embodiment, preferably, the two ends of one side of the second slide plate 6 are fixedly connected with the second clamping blocks 7, the two ends of one side of the first slide plate 4 are provided with second clamping grooves 5, and the second clamping blocks 7 are clamped inside the second clamping grooves 5. By setting the second clamping grooves 5 and the second clamping blocks 7, when in use, the first slide plate 4 and the second slide plate 6 are moved to achieve the clamping or separation of the first slide plate 4 and the second slide plate 6;

[0027] In this embodiment, preferably, the first slide plate 4 and the middle part of one side of the second slide plate 6 are fixedly connected with a snap ring 10, and one side of the snap ring 10 is clamped with a snap ring groove 15. Through the arrangement of the snap ring 10 and the snap ring groove, the first slide plate 4 and the second slide plate 6 are moved during use, so that the snap ring 10 is clamped into the snap ring groove, thereby achieving the effect of pressing the first slide plate 4 and the second slide plate 6 to control the movement of the positioning pin 14;

[0028] In this embodiment, preferably, a spring 17 is fixedly connected to the inner bottom wall of the pin sleeve 16, and a positioning pin 14 is fixedly connected to the top of the spring 17. By setting the spring 17, the pin sleeve 16 and the positioning pin 14, the first slide plate 4 and the second slide plate 6 are pressed during use, so that the positioning pin 14 presses the spring 17, so that the positioning pin 14 can move in the pin sleeve 16;

[0029] In this embodiment, preferably, the limiting blocks 18 are fixedly connected on both sides of the locating pin 14. Through the setting of the limiting blocks 18, the limiting blocks 18 limit the locating pin 14 when in use, so as to prevent the locating pin 14 from being ejected out of the pin sleeve 16 by the spring 17 when in use. The gap between the locating pin 14 and the pin sleeve 16 is set to 0.05-0.1 mm, and the gap between the locating pin 14 and the pin sleeve 16 is used to ensure the accuracy of positioning.

[0030] When a floating positioning assembly for injection molding equipment of the present embodiment is in use, when the positioning pin 14 is damaged or needs to be replaced after long-term use, the operator can separate the first clamping block 2 and the first clamping groove 13, thereby separating the cover plate 11 and the base 1, thereby achieving the effect of removing the positioning pin 14, avoiding the situation that the positioning pin 14 is damaged or needs to be replaced during use, which is difficult to disassemble and replace, causing the operator to be time-consuming and labor-intensive to replace. When the positioning pin 14 is stuck with the injection molding equipment to be positioned, the operator slides the first slide plate 4 and the second slide plate 6 to engage the second clamping block 7 and the second clamping groove 5, and the clamping ring 10 is engaged in the clamping ring groove 15, thereby achieving the effect of controlling the positioning pin 14 by pressing the first slide plate 4 and the second slide plate 6, and then presses the first slide plate 4 and the second slide plate 6 to disengage the positioning pin 14 from the positioning hole to be positioned, thereby avoiding the situation that the positioning pin 14 is difficult to disengage from the injection molding equipment.
