Technical Field
[0001] The utility model relates to the technical field of plastic processing, and particularly relates to an internal connection demoulding track device in a bottle cap injection molding machine. Background Art
[0002] An injection molding machine, also known as an injection molding press or an injection machine, is the main molding equipment for manufacturing various shaped plastic products by using thermoplastic or thermosetting plastics with plastic molding dies;
[0003] The work of an injection molding machine mainly involves injecting the plastic in a molten state (i.e., viscous flow state) that has been plasticized well into a closed mold cavity by means of the thrust of a screw (or a plunger). After solidification and shaping, the process of obtaining the product is achieved. Before and after the mold is closed, the mold is usually driven to close and demold according to the feeding movement of an external shaft rail device. The nozzle structure deep in the mold cavity needs to cooperate with the movement of the demolding track for the subsequent demolding. To a certain extent, there is wear between the edge of the nozzle and the mold cavity, and there is a lack of a track device to provide demolding auxiliary force while positioning the demolding direction. Summary of the Utility Model

[0006] An internal connection demoulding track device in a bottle cap injection molding machine includes a side seat and an outer groove plate. The outer groove plate is arranged on one side of the side seat. The outer groove plate is an arched panel with a plurality of mold cavity orifices on its surface, and L-shaped edges protrude from both sides of the outer groove plate. A fastening member is fixedly clamped between the edge of the outer groove plate and the side seat;
[0007] One end of the side seat is fixedly provided with a main slide rail. A secondary slide rail is arranged in parallel on one side of the main slide rail. One end of the secondary slide rail is fixedly provided with a side plate member between it and the side seat, and the other end is fixedly provided with a spring shaft. A rail kit is slidably arranged on the main slide rail and the secondary slide rail.
[0008] Furthermore, a column shaft penetrates through the outer end of the fastening part between the side seat and the outer groove plate.
[0009] Furthermore, a rail seat is fixedly arranged at one end of the rail kit close to the main slide rail, and a clamping surface is formed on the upper surface of the rail seat.
[0010] Furthermore, an inner sliding disk is rotatably arranged in the rail seat, and the inner sliding disk is in rolling cooperation with the surface of the main slide rail.
[0011] Furthermore, a ball joint is slidably arranged between the rail kit and the main slide rail and the secondary slide rail.
[0012] Furthermore, a partition board with a relatively large diameter is separated between the spring end of the spring shaft and the rail kit.
[0013] Furthermore, expansion screw holes are provided by drilling at one ends of the spring shaft and the main slide rail relative to the side seat.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] Please refer to Figures 1 - 3 , and further illustrate the embodiments of the present utility model;
[0021] An internal demoulding track device of a bottle cap injection molding machine includes a side seat 1 and an outer groove plate 3. The outer groove plate 3 is arranged on one side of the side seat 1. The outer groove plate 3 is an arched panel member with a plurality of cavity orifices opened on its surface, and L-shaped edges protrude from both sides of the outer groove plate 3. A fastening member 11 is fastened and fixed between the edge of the outer groove plate 3 and the side seat 1;
[0022] One end of the side seat 1 is fixed with a main slide rail 2. A branch slide rail 5 is arranged in parallel on one side of the main slide rail 2. One end of the branch slide rail 5 is fixed with a side plate member 4 between it and the side seat 1, and the other end is fixed with a spring shaft 8. A rail kit 6 is slidably arranged on the main slide rail 2 and the branch slide rail 5.
[0023] The device mainly locates the side seat 1 and the outer groove plate 3 through the track structures of the main slide rail 2 and the support slide rail 5. Among them, the rail kit 6 serves as the connection end of the device connected to the mold inside. The rail kit 6 can slide along the main slide rail 2 and the support slide rail 5 to adjust the positions of the side seat 1 and its outer groove plate 3. The outer groove plate 3 serves as the external connection end of the mold cavity surface during mold closing. The outer groove plate arch surface structure is butt - matched with the mold cavity surface, and the mold cavity orifices opened on the surface are aligned with the mold cavity;
[0024] During the mold - closing process, mainly through the mold - closing sliding of the end face, the nozzle structure passes through the outer groove plate 3 and enters the mold cavity. The outer groove plate 3 serves as the contact structure of the nozzle outer end face during mold closing. When the mold is closed, the compression of the outer groove plate 3 will axially press the main slide rail 2 and the support slide rail 5, and the synchronous sliding of the rail kit 6 is used to compress the spring shaft 8, so as to improve the positioning accuracy during the mold - closing process. At the same time, during the demolding process, the demolding force after mold closing will use the acting force of the spring shaft 8 to assist the nozzle structure in demolding, improving the practicability of the device.
[0025] Preferably, a column shaft 12 is penetrated and arranged at the outer end of the fastening part between the side seat 1 and the outer groove plate 3. The column shaft 12 is perpendicular to the fastening end of the outer groove plate 3 and the side seat 1, so as to further cooperate with the fastening edge of the outer groove plate 3 for axial connection reinforcement with the side seat 1.
[0026] Preferably, a rail seat 7 is fixedly arranged at one end of the rail kit 6 close to the main slide rail 2. A clamping surface is formed on the upper surface of the rail seat 7. The rail kit 6 is further fixed to the mold through the rail seat 7 at the end face, and its clamping surface can be bolt - connected and combined with the mold end face.
[0027] Preferably, an inner sliding disk 9 is rotatably arranged in the rail seat 7. The inner sliding disk 9 is in rolling fit with the surface of the main slide rail 2. The inner sliding disk 9 serves as the attachment structure between the rail seat 7 and the main slide rail 2. A sliding - distance sensor can be installed on the inner sliding disk 9 to monitor the sliding distance between the rail kit 6 and the main slide rail 2.
[0028] Preferably, ball joints 10 are slidably fitted between the rail kit 6 and the main slide rail 2 and the support slide rail 5. By arranging the ball joints 10 at the sliding ends, the sliding smoothness between the rail kit 6 and the main slide rail 2 and the support slide rail 5 is improved.
[0029] Preferably, a partition with a relatively large diameter is separated between the spring end of the spring shaft 8 and the rail kit 6. By cooperating with the partition arranged between the spring shaft 8 and the rail kit 6, the contact surface of the rail kit 6 when axially compressing the spring shaft 8 is widened to ensure the stable compression of the spring parts of the spring shaft 8.
[0030] Preferably, expansion screw holes are opened at one ends of the spring shaft 8 and the main slide rail 2 relative to the side seat 1. Both the main slide rail 2 and the end of the spring shaft 8 can correspond to the inner connection end of the mold through the expansion screw holes. The axial positions of the main slide rail 2 and the support slide rail 5 in the mold are restricted by axially extending expansion bolts.
[0031] The implementation of the device lies in that:
[0032] During the mold closing process, the nozzle structure of the injection molding machine slides along the end face of the mold closing structure to make the nozzle structure pass through the outer groove plate 3 and enter the mold cavity. The outer groove plate 3 is used as the contact structure for the outer end face of the nozzle during mold closing. When the mold is closed, the pressure on the outer groove plate 3 will axially press the main slide rail 2 and the support slide rail 5, and use the synchronous sliding of the rail kit 6 to compress the spring shaft 8, so as to improve the positioning accuracy during the mold closing process through the track structure. At the same time, during the demolding process, the separated nozzle end is used to demold with the demolding force in the mold closing state, and the spring shaft 8 is used to assist the nozzle structure to demold.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
