[0001] This utility model relates to the field of injection molding technology, and in particular to a quick-connect injection molding interface device for rubber products. Background Technology

[0002] Rubber injection molding is a manufacturing method in which rubber compound is heated using an injection molding machine, then injected under pressure from the barrel into a sealed mold, and finally vulcanized under pressure to form a finished product. This method can process products with complex shapes and precise dimensions, and has high production efficiency.

[0003] In the prior art, most traditional injection molding machine connectors are installed at the discharge end of the injection cylinder using a threaded connection. This connection method has certain drawbacks, such as the threaded connection being easily loosened due to vibrations generated during machine operation. In addition, the threaded connection is prone to stripping and damage due to frequent disassembly. Therefore, this utility model proposes a quick-connect rubber product injection molding interface device to solve the above problems. Utility Model Content

One end of the outer bushing is closed, and the other end is open. The injection head is fixedly connected to one end of the outer bushing and extends outside the outer bushing. Two symmetrically arranged limiting grooves are provided on the inner wall of the outer bushing. Two limiting strips corresponding to the two limiting grooves are fixedly connected to the outer wall of the injection cylinder. A positioning rod is slidably connected through the inner wall of each of the two limiting grooves. A positioning hole is provided at the upper end of each of the two limiting strips.

[0007] Preferably, the upper ends of both positioning rods are fixedly connected to handles, and the lower ends of both handles are elastically connected to the outer wall of the outer bushing via a second spring.

[0008] Preferably, the injection head is fitted with the injection barrel, and a sealing ring is provided on the outer wall of the end of the injection head near the injection barrel.

[0009] Preferably, a retaining ring is slidably sleeved on the injection head located inside the outer bushing, and the retaining ring is elastically connected to the inner wall of the outer bushing by a first spring.

[0010] Preferably, a plurality of heating sleeves arranged at equal intervals are fixedly sleeved on the outer wall of the injection molding cylinder.

[0011] Preferably, both handles are provided with protective sleeves, the protective sleeves being made of fluororubber.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting limit strips, positioning holes, and positioning rods, during docking, pull the handles on both sides to move the positioning rods out of the limit grooves, align the injection head of the connector body with the injection cylinder and insert it, so that the two limit strips are inserted into the limit grooves on both sides. After insertion, release the handles and push the connector body to one side of the injection cylinder, so that the positioning rods move on the limit strips. When it moves to the set position, under the action of the second spring, the positioning rods return to the positioning holes on the limit strips, realizing quick docking of the connector bodies. The installation process is convenient and has high stability, making it suitable for frequent disassembly.

[0014] 2. By setting limit strips and limit grooves, the limit strips are inserted into the limit grooves during docking to achieve rapid positioning.

[0015] 3. By setting a first spring and a retaining ring, the first spring contracts after docking under the action of the retaining ring, and the resulting elastic force can press against the joint body, ensuring greater stability. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1-5 A quick-connect rubber product injection molding interface device includes an injection cylinder 1 and a connector body 2. The connector body 2 consists of an outer bushing 201 and an injection head 202. One end of the outer bushing 201 is closed and the other end is open. The injection head 202 is fixedly connected to one end of the outer bushing 201 and extends to the outside of the outer bushing 201. Two symmetrically arranged limiting grooves 204 are opened on the inner wall of the outer bushing 201. Two limiting strips 102 corresponding to the two limiting grooves 204 are fixedly connected to the outer wall of the injection cylinder 1. Positioning rods 208 are slidably connected through the inner walls of the two limiting grooves 204. Positioning holes 103 are opened at the upper ends of the two limiting strips 102.

[0024] Specifically, the upper ends of the two positioning rods 208 are fixedly connected to handles 206, and the lower ends of the two handles 206 are elastically connected to the outer wall of the outer bushing 201 by a second spring 207.

[0025] Specifically, the injection head 202 is matched with the injection cylinder 1, and a sealing ring is provided on the outer wall of the end of the injection head 202 near the injection cylinder 1. The sealing ring is a metal sealing ring and its material is a nickel-based alloy.

[0026] Specifically, a retaining ring 205 is slidably sleeved on the injection head 202 located inside the outer bushing 201. The retaining ring 205 is elastically connected to the inner wall of the outer bushing 201 by a first spring 203. When disassembling, the first spring 203 can drive the retaining ring 205 to reset and pop out the connector body 2, making it easy to remove the connector body 2.

[0027] Specifically, multiple heating sleeves 101 with equal spacing are fixedly sleeved on the outer wall of the injection cylinder 1, and protective sleeves are provided on both handles 206. The protective sleeves are made of fluororubber. In addition to its excellent high temperature resistance, fluororubber also has a relatively outstanding heat insulation effect. It can maintain a stable molecular structure at high temperatures, effectively prevent heat conduction, and has good heat insulation performance, making it suitable for use in injection molding heads.

[0028] When using this invention, during docking, pull the handles 206 on both sides to move the positioning rod 208 outward from the limiting groove 204, align the injection head 202 of the connector body 2 with the injection cylinder 1 and insert it, so that the two limiting strips 102 are inserted into the limiting grooves 204 on both sides. After insertion, release the handles 206 and push the connector body 2 to one side of the injection cylinder 1, so that the positioning rod 208 moves on the limiting strip 102. When it moves to the set position, under the action of the second spring 207, the positioning rod 208 resets and inserts into the positioning hole 103 on the limiting strip 102, realizing quick docking of the connector body 2. During disassembly, pull the handles 206 on both sides to pull the positioning rod 208 out of the positioning hole 103, and the connector body 2 can be easily removed. The installation process is convenient and has high stability, making it suitable for frequent disassembly. After docking, squeeze the clamping ring 205, the first spring 203 contracts, and the resulting elastic force can press against the connector body 2, ensuring greater stability.
