Embodiment 1

[0073] The present embodiment provides a needle locking mechanism 2, such as figure 2 , image 3 , Figure 6 to Figure 10 As shown, it includes: an installation body, a clamping part and a driving rod 23 .

[0074] Wherein, the clamping part is fixedly installed in the mounting body; the clamping part has a first clamping head 221 and a second clamping head 222 arranged oppositely, and a clamping opening facing outwards is formed between the first clamping head 221 and the second clamping head 222. The holding cavity 223; the driving rod 23 slides toward the opening side of the clamping cavity 223 relative to the installation body, and abuts against the first chuck 221 during the sliding process to reduce the clamping cavity 223, so that the insert It is detachably installed in the clamping cavity 223 .

[0075] In this example, if Figure 9 and Figure 10 shown along the Figure 9 and Figure 10 From right to left in the Y-axis direction, the first chuck 221 includes ...

Embodiment 2

[0098] This embodiment provides a side core pulling mechanism 3, such as figure 2 , Figure 11 to Figure 17 As shown, it includes a mold frame 41 , a linkage component 11 and a sliding body 31 .

[0099] Wherein, the linkage part 11 and the sliding body 31 are stacked on the formwork 41 along the Z-axis direction, and the linkage part 11 is driven by the driving mechanism to slide left and right relative to the formwork 41 along the horizontal Y-axis direction; 11 is driven to slide relative to the mold frame 41 between the mold clamping position and the mold opening position, and the core 33 is installed on the sliding body 31; the limit assembly 32 is telescopically installed on the sliding body along the vertical Z axis direction 31, and the limit assembly 32 is switched between the first limit position and the second limit position in the telescopic direction when the limit component 32 slides with the sliding body 31.

[0100] Specifically, the limiting assembly 32 sli...

Embodiment 3

[0126] This embodiment provides an injection molding system, such as Figure 1 to Figure 19 As shown, it includes: the card needle mechanism 2 provided in embodiment 1, the side core-pulling mechanism 3 provided in embodiment 2, the driving mechanism and the linkage components of the side core-pulling mechanism in embodiment 2. The linkage part 11 of the partial structure.

[0127] Among them, such as figure 2 As shown, the locking mechanism 2 is installed in the first passage 17 of the linkage part 11; the first passage 17 is arranged through the linkage part 11 along the Y-axis direction; the side core-pulling mechanism 3 is arranged in linkage at the bottom of the linkage part 11 along the Z-axis direction Above; the drive mechanism includes a drive part 51 arranged on the right side of the linkage part 11 along the Y-axis direction, the drive part 51 drives the linkage part 11 to slide along the Y-axis direction, and the drive part 51 and the linkage part 11 are linked t...

Abstract

The invention discloses a needle clamping mechanism and an injection molding system. The clamping needle mechanism comprises a mounting body, a clamping component and a driving rod. The clamping component is arranged on the mounting body, and is provided with a first clamping head and a second clamping head which are oppositely arranged, and a clamping cavity with an opening facing outwards is defined between the first clamping head and the second clamping head. The first clamping head is made of an elastic material. The driving rod is slidably arranged relative to the mounting body. The driving rod is in linkage with the first clamping head, and the first clamping head is switched between a first position separated from the driving rod and a second position which is extruded towards the position ,close to the second clamping head, driven by the driving rod. When the clamping needle mechanism is in the second position, the first clamping head is close to the second clamping head, and the space of the clamping cavity enclosed by the first clamping head and the second clamping head is reduced, an insert is extruded and clamped by the first chuck, and the influence of the injection molding force and the mold closing force in the injection molding process is avoided, the relative position of the insert does not change, and the retainer is kept in the clamping cavity, the injectionmolding is performed at the moment, so that the injection rate of the injection molding is greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic molding and processing, in particular to a locking needle mechanism and an injection molding system. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. Among them, the injection mold is a common mold used to form plastic parts or plastic products, and various forms of plastic parts can be formed through the injection mold to meet people's various needs. [0003] Due to the different process requirements of plastic parts, some molds need to be loaded with inserts to ensure their strength, hardness, or conductivity. Therefore, the insert may not be a single metal. For example, the insert can also be connected to the wire harness, and the end of the wire harness and the insert is connected to the power supply term...
