Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to the plastic injection structure of a vehicle center console. Background Technology

[0002] Currently, with the rapid development of new energy vehicles, the functions of the automotive center console area are becoming increasingly diversified, and its control system is becoming increasingly complex. Consequently, the structure of the center console panel supporting the control system is also becoming more complex, and its outline dimensions are becoming larger. The center console panel is generally molded using plastic molding. The complex structure and large outline dimensions of the product make the structural design of the plastic mold increasingly complex and precise. In particular, the design of the mold's injection structure directly determines the flow rate and direction of the adhesive in the cavity, which in turn directly affects the mechanical strength of the functional structural components on the center console panel and directly affects the appearance of the center console panel.

[0003] Currently, the thickness of automotive center console panels is relatively small compared to their length and width. Therefore, most injection molding processes use multi-point injection molding. However, in actual production, due to factors such as room temperature, environment, or manufacturing or assembly errors of the mold itself, some injection points far from the main flow path may have a slower flow rate than theoretically designed. This can lead to defects such as bubbles, white spots, black residue, or even incomplete filling in the plastic product. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a plastic injection structure for a vehicle center console. By setting several hot nozzles on the injection path of the sprue plate, the molten plastic can enter the mold cavity after temperature regulation by each hot nozzle. With the help of the cooling water jacket at the end of each hot nozzle, the temperature and flow rate of the molten plastic at the outlet of each hot nozzle (i.e., the injection point) can be precisely controlled by the cooling system. This ensures that the actual injection parameters are consistent with the set parameters, avoids injection defects caused by objective factors, and ensures injection quality and yield.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The plastic injection structure of the vehicle center console is provided on the fixed mold of the plastic mold, including a liquid storage tank and a glue injection passage connected thereto. The liquid storage tank is provided on the fixed mold base, and the glue injection passage is connected to a cavity provided on the fixed mold core. The fixed mold core is embedded in the end of the moving mold plate facing the moving mold. A sprue plate and a guide are also provided on the fixed mold between the fixed mold base and the fixed mold plate. Several hot nozzles are fixed on the sprue plate. One end of each hot nozzle is connected to the glue injection passage, and the other end passes through the sprue plate, the guide, the fixed mold plate and the fixed mold core in sequence and extends to the side wall of the cavity. A cooling water jacket is provided around the end of each hot nozzle near the cavity. The end of each cooling water jacket away from the cavity is sealed and connected to the water cooling pipe in the plastic mold. Each cooling water jacket is embedded in the fixed mold core.

[0007] As a further explanation of the above technical solution:

[0008] In the above technical solution, the fixed mold core is provided with a plurality of first mounting grooves at the end opposite to the cavity, and a cooling water jacket can be fitted into each of the first mounting grooves, and a sealing sleeve is fitted at the end of each cooling water jacket; the fixed mold plate is provided with a plurality of second mounting grooves that are adapted to the sealing sleeves one by one, and the bottom of each second mounting groove is provided with one or more connecting holes that are connected to the water cooling pipes.

[0009] In the above technical solution, the guide component includes a guide plate and one or more guide sleeves embedded thereon: each guide sleeve has one or more through holes that are adapted to each of the hot nozzles; the guide plate is sleeved on a plurality of guide posts, one end of each guide post is detachably fixed to the sprue plate, and the other end abuts against the fixed template.

[0010] In the above technical solution, a limiting plate is also provided on the side of the guide plate facing the fixed template. The limiting plate is sleeved around each guide post and slidably connected to it. Several buffer springs are provided between the limiting plate and the sprue plate. The sum of the heights of the limiting plate and the guide plate is less than the height of each guide post.

[0011] In the above technical solution, two pads are provided around the periphery of several guide pillars between the sprue plate and the fixed template, and the two ends of each pad abut against the sprue plate and the fixed template respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting several hot nozzles on the glue inlet passage of the sprue plate, the glue can enter the cavity after the temperature is controlled by each hot nozzle. With the cooling water jacket at the end of each hot nozzle, the temperature and flow rate of the glue at the liquid outlet of each hot nozzle 60, i.e. the glue inlet point, can be precisely controlled by the cooling system, so that the actual glue injection parameters are consistent with the set parameters, avoiding injection defects caused by objective factors, and ensuring injection quality and yield.

[0020] like Figure 1-2As shown, the injection structure of the vehicle center console is located on the fixed mold of the mold, including a liquid storage tank and an injection passage connected thereto. The liquid storage tank is located on the fixed mold base 10, and the injection passage is connected to the cavity located on the fixed mold core 20. The fixed mold core 20 is embedded in the end of the moving mold plate 30 facing the moving mold. A sprue plate 40 and a guide 50 are also provided on the fixed mold between the fixed mold base 10 and the fixed mold plate 30. Several hot nozzles 60 are fixed on the sprue plate 40. One end of each hot nozzle 60 is connected to the injection passage, and the other end passes through the sprue plate 40, the guide, the fixed mold plate 30 and the fixed mold core 20 in sequence and extends to the side wall of the cavity. A cooling water jacket 70 is provided around the end of each hot nozzle 60 near the cavity. The end of each cooling water jacket 70 away from the cavity is sealed to the water cooling pipe in the mold. Each cooling water jacket 70 is embedded in the fixed mold core 20.

[0021] This invention sets several hot nozzles 60 on the glue inlet passage of the sprue plate 40, so that the glue can enter the mold cavity after the temperature is regulated by each hot nozzle 60. In conjunction with the mold cooling system, the temperature and flow rate of the glue at the outlet (glue inlet) of each hot nozzle 60 can be precisely controlled, so that the actual glue injection parameters are consistent with the set parameters, avoiding injection defects caused by objective factors, and ensuring injection quality and yield.

[0022] like Figure 3-4 As shown, the fixed mold core 20 has several first mounting grooves 1 at the end away from the cavity. Each first mounting groove 1 can be fitted with a cooling water jacket 70. Each cooling water jacket 70 has a sealing sleeve 80 at its end. The fixed mold plate 30 has several second mounting grooves 2 that are adapted to the sealing sleeves 80. Each second mounting groove 2 has one or more connecting hole grooves 3 at its bottom that are connected to the water cooling pipes.

[0023] In this embodiment, each hot nozzle 60 is surrounded by an arc-shaped cooling water jacket 70 at its end, which can quickly cool the outlet temperature of the hot nozzle 60. Several cooling water jackets 70 are also embedded on the side of several hot nozzles 60 on the fixed mold core 20, which can cool the fixed mold core 20, thereby adjusting the temperature of the inner wall of the cavity and thus affecting the cooling rate of the adhesive in the cavity, and assisting in adjusting the condensation rate of the plastic product 100.

[0024] The hot nozzle 60 is a plastic injection assembly that includes a temperature controller and is designed to heat the plastic liquid inside. Its structure and assembly are existing technologies and will not be described in detail here.

[0025] like Figure 2As shown, the guide includes a guide plate 51 and one or more guide sleeves 52 embedded thereon: each guide sleeve 52 has one or more through holes 4 that are adapted to the hot nozzles 60; the guide plate 51 is sleeved on a number of guide posts 53, one end of each guide post 53 is detachably fixed to the sprue plate 40, and the other end abuts against the fixed template 30; a limiting plate 54 is also provided on the side of the guide plate 51 facing the fixed template 30, the limiting plate 54 is sleeved on the periphery of each guide post 51 and is slidably connected to it, and a number of buffer springs 5 ​​are provided between the limiting plate 54 and the sprue plate 40; the sum of the heights of the limiting plate 54 and the guide plate 51 is less than the height of each guide post 53.

[0026] Understandably, the guide sleeve 52 can guide each hot nozzle 60 to ensure the accuracy of its end, i.e., the injection point, position; at the same time, the limiting plate 54 and the buffer spring 5 between it and the sprue plate 40 can reduce the impact force of the moving mold's pushing force on the sprue plate 40 when the mold is closed, ensuring that the injection passage and each hot nozzle 60 are always in the set position and remain stable during the injection molding process, ensuring the stability and consistency of the injection molded product quality.

[0027] like Figure 1-2 As shown, two pads 90 are provided around several guide posts 53 between the sprue plate 40 and the fixed template 30, with each pad 90 having its two ends abutting against the sprue plate 40 and the fixed template 30 respectively.

[0028] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
