Description

Technical Field

[0001] This application relates to the field of temperature measurement of heating components, and in particular to a temperature measurement structure for heating components in injection molding equipment. Background Technology

[0002] The temperature measuring structure of the heating component in injection molding equipment is used to monitor the temperature at the heating nozzle and transmit the data back to the control system in a timely manner, so that the staff can adjust the temperature in a timely manner.

[0003] Currently, in actual use, the temperature measurement structure of the heating components in injection molding equipment has the sensor located at the tail of the nozzle, which is far from the nozzle opening. When monitoring the temperature, it is impossible to collect the temperature at the nozzle in a timely and accurate manner, which affects the judgment of the operator and leads to problems with untimely temperature control. Utility Model Content

[0004] To improve the problem of untimely temperature control, this application provides a temperature measurement structure for the heating component in an injection molding machine.

[0005] The temperature measuring structure of the heating component in the injection molding equipment provided in this application adopts the following technical solution:

[0006] A temperature measuring structure for a heating component in an injection molding machine includes a nozzle, wherein an installation mechanism is provided inside the nozzle;

[0007] The mounting mechanism includes a wiring groove on the outer wall of the nozzle for sensor wiring, an mounting groove for sensor installation on the outer wall of the nozzle at an incline, a hollow hole for material flow through the inner wall of the nozzle, and a gathering groove at the end of the hollow hole.

[0008] By adopting the above technical solution, the bottom of the mounting groove is connected to the top of the hollow hole, so that the sensor can detect the temperature status in advance when the gathering groove gathers the internal material. This makes it more convenient, timely and accurate to monitor the temperature, and allows for timely arrangement of the sensor circuitry to avoid interference with the monitoring.

[0009] Preferably, the mounting mechanism further includes an output hole that extends through the inside of the nozzle, with the top of the hollow hole communicating with the mounting groove.

[0010] By adopting the above technical solution, the output hole penetrates through the port of the nozzle, thereby concentrating the material output.

[0011] Preferably, the outer wall of the nozzle is provided with a protective mechanism, the protective mechanism including a protective ring sleeved on the outer wall of the nozzle, and a limiting ring fixedly sleeved on the outer wall of the nozzle.

[0012] By adopting the above technical solution, the limiting ring is set at both ends of the protective ring, thereby limiting the protective ring.

[0013] Preferably, a linkage ring is fixedly connected to the outer wall of the protective ring, and a positioning plate is fixedly connected to the outer wall of the linkage ring.

[0014] By adopting the above technical solution, the outer diameter of the linkage ring is kept consistent with that of the limiting ring, thereby facilitating the friction between the protective ring and the limiting ring.

[0015] Preferably, the top of the positioning plate is fixedly connected to a connecting plate that is fixedly connected to the side wall of the linkage ring.

[0016] By adopting the above technical solution, the side of the positioning plate near the limiting ring is in contact with the limiting ring, which facilitates the limiting.

[0017] Preferably, the connecting plate has screws threaded through its sidewall.

[0018] By adopting the above technical solution, the screw is set horizontally, which makes it easy to move the screw horizontally by rotating it.

[0019] Preferably, an alignment plate is fixedly connected to the outer wall of the limiting ring.

[0020] By adopting the above technical solution, the alignment plate can maintain the same height as the connecting plate through the rotation of the limiting ring, thus facilitating the connection.

[0021] Preferably, the alignment plate has a through mounting hole in its side wall.

[0022] By adopting the above technical solution, the diameter of the mounting hole is larger than the diameter of the screw rod, which facilitates the screw to pass through.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By tilting the sensor inside the mounting slot and then arranging the sensor's wiring inside the wiring slot, the sensor is pre-installed. Compared to existing sensor installation positions, the sensor is closer to the nozzle in this structure, resulting in more accurate temperature sensing. The wiring slot also prevents the sensor wiring from interfering with the process during operation. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] This application discloses a temperature measuring structure for a heating component in an injection molding machine.

[0037] Example 1:

[0038] Reference Figure 1 , Figure 2 A temperature measuring structure for a heating component in an injection molding machine includes a nozzle 1, an installation mechanism 2 inside the nozzle 1, and a protective mechanism 3 on the outer wall of the nozzle 1. The installation mechanism 2 includes a wiring groove 21 located at the top of the nozzle 1, an installation groove 22 inclined and penetrating the top of the nozzle 1, a hollow hole 23 horizontally penetrating the inner wall of the nozzle 1 for material flow, a gathering groove 24 opened at the end of the hollow hole 23, the gathering groove 24 being a horizontally placed frustum-shaped structure for reducing the cross-sectional area of ​​the flow opening, and the installation mechanism 2 also includes an output hole 25 penetrating inside the nozzle 1. The installation groove 22 is in communication with the top of the hollow hole 23, so that the receiving end of the sensor can contact the material inside the hollow hole 23.

[0039] The operator inserts the sensor into the mounting slot 22, extends the sensor receiver into the hollow hole 23, and then arranges the sensor's connection lines inside the wiring slot 21, thus completing the sensor installation and wiring arrangement. The mounting slot 22 is a space for sensor installation. After installation, the sensor occupies the space of the mounting slot 22 and engages with it, allowing the sensor receiver to perform temperature monitoring within the hollow hole 23.

[0040] Example 2:

[0041] Reference Figures 3-6 A protective ring 31 is fitted onto the outer wall of the nozzle 1, with its inner diameter matching that of the nozzle 1. An opening is provided at the top of the protective ring 31, allowing the wiring groove 21 to be positioned within this opening during sensor wiring installation, thus preventing interference with the wiring installation. A limiting ring 32 is fixedly fitted onto the outer wall of the nozzle 1, with its side closest to the protective ring 31 fitting against the protective ring 31 to limit its movement. A linkage ring 33 is fixedly connected to the outer wall of the protective ring 31. The linkage ring 33 is fitted with the limiting ring 32. The positioning plate 34 is fixedly connected to the outer wall of the linkage ring 33. The top of the positioning plate 34 is fixedly connected to the connecting plate 35. The connecting plate 35 is fixedly connected to the side wall of the linkage ring 33, which facilitates structural control. A threaded hole is opened through the side wall of the connecting plate 35. The screw 36 is threaded through the threaded hole, so that the screw 36 is threadedly connected to the connecting plate 35. The alignment plate 37 is fixedly connected to the outer wall of the limiting ring 32. The mounting hole 38 is opened through the side wall of the alignment plate 37.

[0042] The operator rotates the protective ring 31, which in turn rotates the linkage ring 33. The linkage ring 33 then rotates the alignment plate 37, causing the alignment plate 37 to align with the top of the positioning plate 34. This aligns the mounting hole 38 with the screw 36, and the protective ring 31 shields the wiring groove 21. The operator then rotates the screw 36, causing it to move horizontally and pass through both the connecting plate 35 and the alignment plate 37, thus securing the protective ring 31 and protecting the sensor's wiring.

[0043] When the protective ring 31 blocks the wiring groove 21, the protective ring 31 and the outer wall of the nozzle 1 are in close contact to protect the sensor wiring, thereby preventing materials from entering the wiring groove 21.

[0044] The implementation principle of the temperature measuring structure of the heating component in the injection molding equipment according to the embodiments of this application is as follows:

[0045] The operator inserts the sensor into the mounting slot 22, extends the sensor receiver into the hollow hole 23, and then arranges the sensor's connection lines inside the wiring slot 21, thus completing the sensor installation. After use, when the device is stationary, if it is necessary to protect the wiring slot 21, the operator fixes the limiting ring 32 to the nozzle 1, then puts the protective ring 31 on the outer wall of the nozzle 1, and then rotates the protective ring 31. The protective ring 31 will drive the alignment plate 37 to rotate, and the alignment plate 37 will fit against the top of the positioning plate 34, so that the mounting hole 38 is aligned with the screw 36. The protective ring 31 protects the wiring slot 21. Then the operator rotates the screw 36, so that the screw 36 moves horizontally, so that the screw 36 passes through both the connecting plate 35 and the alignment plate 37.

[0046] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
