Technical Field

[0001] The invention relates to the technical field of moulds, in particular to a mould which is easy to fix. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. Injection molds are molds used to manufacture injection molded products. In the actual production process, the molten plastic material is usually stirred evenly by a screw extruder at a certain temperature, and then injected into the injection mold. The plastic material is molded in the cavity of the injection mold, and the molded injection molded product is obtained after cooling and solidification.

[0003] The mold generally includes two parts, an upper mold and a lower mold, and there is no connection between the two parts. Therefore, once an external force touches the mold, it is easy to cause the upper mold and the lower mold to shift in position, affecting the molding effect. For this reason, in the prior art, before the mold is used, a combination of screws and pins is usually used to fix the upper mold and the lower mold together to avoid separation of the mold and ensure the molding effect. The screws mainly play a tightening role. When assembling and disassembling the mold, the staff need to use a manual wrench or an electric wrench to remove the screws. There are many screws, especially for large molds. The screws used for connection range from hundreds to thousands.

[0027] See also Figure 4-6As shown, a plurality of slideways 14 are provided on the partition, a connecting seat 15 is provided on the latch tongue 12, and a slider 16 penetrating the slideway 14 is provided on the connecting seat 15. The adjusting mechanism comprises an adjusting dial 17 rotatably connected to the inside of the adjusting groove 11, and a plurality of guide grooves 18 are evenly provided on the adjusting dial 17. The trajectory direction of the guide groove 18 extends outward in a clockwise direction with the center of the circle of the adjusting dial 17 as the center, and a pulley 19 slidably connected to the inside of the guide groove 18 is provided on the slider 16. By rotating the adjusting dial 17, the guide groove 18 can be moved, thereby squeezing the pulley 19 to slide along the trajectory direction of the guide groove 18. When the pulley 19 slides, the slider 16 can be driven to move accordingly. The slider 16 is limited by the slideway 14 and cannot move in the sliding direction of the pulley 19, but can only slide along the length direction of the slideway 14, thereby driving the latch tongue 12 to perform telescopic movement accordingly, realizing locking and unlocking. The operation is relatively convenient and simple, saving time and effort.

[0028] See also Figure 5 As shown, a plurality of guide wheels 20 are rotatably connected inside the adjusting groove 11, and the adjusting dial 17 is rotatably matched with the guide wheels 20. When the adjusting dial 17 rotates, its edge will move on the inner concave surface of the guide wheel 20, thereby driving the guide wheel 20 to rotate.

Guide rails 21 are provided on both sides of the slide 14 inside the storage groove 10, and a sliding member 22 slidably connected to the guide rails 21 is provided on the tongue 12. When the slider 16 slides in the slide 14, the sliding member 22 will slide along the length direction of the guide rail 21. The extension and retraction of the tongue 12 can be smoother through the limitation of the sliding member 22 by the guide rail 21.

[0029] See also Figure 1 , Figure 5 As shown, a rotating column 23 that penetrates the shell 5 and extends out of the shell 5 is provided at the center position of the adjusting dial 17. By screwing the rotating column 23, the adjusting dial 17 can be driven to rotate accordingly, and the operation is relatively convenient and simple. A force-applying groove is provided at the end of the rotating column 23 away from the adjusting dial 17. By inserting a screwdriver into the force-applying groove and rotating it, the rotating column 23 can be driven to rotate, thereby driving the adjusting dial 17 to rotate accordingly. The setting of the force-applying groove can provide a force point for the operation of rotating the adjusting dial 17, thereby making the operation easier and more labor-saving.

[0030] See also Figure 4-6As shown, the end face of the latch 12 is arc-shaped, so that the latch 12 can be inserted into the slot 13 more smoothly without being blocked, and there are four latches 12, which are symmetrically distributed in a cross with the central axis of the shell 5 as the center. After the latch 12 is inserted into the slot 13, it can be locked in the cross direction, thereby improving the connection firmness between the upper mold 1 and the lower mold 2. The latch 12 is detachably mounted on the connecting seat 15. When the latch 12 is deformed due to long-term use, it can be removed from the connecting seat 15 and replaced to avoid being unable to be inserted. The situation ensures the use effect of the locking device, wherein a connecting plate 24 is provided on the connecting seat 15, and a plurality of through holes are opened on the connecting plate 24, a screw rod 25 for penetrating the through holes is provided on the latch tongue 12, and a nut 26 is threadedly connected to the screw rod 25. When the latch tongue 12 is installed, the screw rod 25 can be penetrated through the through holes and then fixed by the nut 26. When the latch tongue 12 needs to be removed, it is only necessary to remove the nut 26 from the screw rod 25 and then pull the screw 25 out of the through holes, thereby making the disassembly and assembly of the latch tongue 12 more convenient and simple.
