Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a mold for manufacturing baby seats. Background Art

[0002] A baby seat, as the name implies, is a seat designed specifically for children, providing protection for children's safety. In particular, an in-vehicle child safety seat can effectively improve the safety of children when riding by restraining the child in the safety seat. With the rapid development of society and the continuous improvement of safety awareness, the demand for child seats is becoming more and more extensive, and the structure of child seats needs to be continuously improved. Therefore, it is necessary to develop corresponding molds for the main body of child seats. The prior art, such as a mold for the main body of a child seat disclosed in the patent No. CN208745244U, includes a seat shape, an upper code template, a lower code template, a female mold and a male mold. This technical solution can achieve the efficient production of the main body of a child seat, with simple operation, high production efficiency, relatively high product size accuracy and good product quality.

[0003] Combined with the content of this prior art and the attached drawings, in actual use, the hot runner system of the mold has a fixed position when pouring molten raw materials, and the gate at the end is located at the top of the mold cavity. The pouring height cannot be adjusted according to the pouring volume, which is likely to cause internal hollow defects in the product during the pouring process. Based on this, we designed a mold for manufacturing baby seats. Summary of the Invention

[0004] The purpose of the utility model is to provide a mold for manufacturing baby seats to solve the problems raised in the above background art.

[0005] The purpose of the utility model can be realized by the following technical solutions: A mold for manufacturing baby seats includes an upper seat mold base, a lower seat mold base, a mold top plate and a hot pouring runner pipe. The upper seat mold base and the lower seat mold base are connected by mold inserts for clamping. The mold top plate is assembled on the top of the upper seat mold base through bolts. A pouring channel is arranged at the center of the top of the mold top plate. The tail end of the hot pouring runner pipe passes through the pouring channel and is located in the mold cavity of the upper seat mold base and the lower seat mold base. An injection molding machine joint is arranged at the top of the hot pouring runner pipe. A fixed vertical plate is arranged on the back of the lower seat mold base. A sliding connecting rod is installed on the side of the fixed vertical plate. A connecting bar is arranged at the top of the sliding connecting rod. One end of the connecting bar is provided with a pipe limiting frame, and the pipe limiting frame is connected to the hot pouring runner pipe.

[0006] In the above-mentioned mold for manufacturing a baby seat, a mold stabilizing assembly is further included. The mold stabilizing assembly includes an upper pressing plate, a lower connecting plate, and a plugging bar. The top end of the lower connecting plate is connected to the upper pressing plate. A protruding bar is provided on the side of the lower connecting plate. A clamping groove is formed between the protruding bar and the upper pressing plate, and this clamping groove is clamped with the mold top plate. The plugging bar is located at the bottom of the lower connecting plate and is plugged with the lower seat mold base. The purpose of such a setting is to enable a good connection tightness between the upper seat mold base and the lower seat mold base. During the injection molding raw material stage, it avoids an increase in the gap between the upper seat mold base and the lower seat mold base caused by excessive pressure, thereby preventing a decline in injection molding accuracy. This effectively ensures good injection molding quality during the injection molding process.

[0007] In the above-mentioned mold for manufacturing a baby seat, an extrusion block is provided at the top end of the mold top plate. A limiting port is provided at the side of the top end of the upper pressing plate and corresponds to the extrusion block. A locking bolt is installed at the top end of the upper pressing plate, and the locking bolt is connected to the screw hole of the mold top plate. The purpose of such a setting is to facilitate better connection of the upper pressing plate to the mold top plate, enabling good connection stability between the mold top plate and the entire mold stabilizing assembly and the lower seat mold base.

[0008] In the above-mentioned mold for manufacturing a baby seat, a heat-absorbing back plate is further included. A limiting strip is integrally formed on the side of the heat-absorbing back plate. An installation hole groove is provided on the side of the upper seat mold base. The heat-absorbing back plate is connected to the side of the upper seat mold base through the limiting strip. The purpose of such a setting is to have a good heat absorption effect. During the injection molding cooling stage, it can quickly absorb heat to the heat-absorbing back plate, accelerating the cooling and forming process.

[0009] In the above-mentioned mold for manufacturing a baby seat, a condensation pipe distributed in an S shape is installed on the back of the heat-absorbing back plate. A threaded connector is provided at the water inlet of the condensation pipe. The purpose of such a setting is to facilitate the access of water flow, enabling the water flow to flow in the S-shaped distributed condensation pipe, thereby transferring heat to the water and quickly taking it away, achieving the effect of rapid cooling.

[0010] Compared with the prior art, the advantages of the mold for manufacturing the baby seat of the present utility model are as follows: By arranging a fixed vertical plate on the back of the lower seat mold base, a sliding connecting rod capable of adjusting up and down is arranged at the fixed vertical plate, and the sliding connecting rod is connected to the hot casting runner pipe through a connecting strip and a pipe limiting frame, so as to realize the adjustment of the casting height during the casting process, and further be able to adjust the overall height of the hot casting runner pipe according to the molten amount of the casting, avoiding the internal hollow defect of the product during the casting process, and effectively ensuring the quality of the casting; By arranging a mold stabilizing component, the mold stabilizing component includes an upper pressing plate, a lower connecting plate and a plugging strip, so that there is a good connection fastening degree between the upper seat mold base and the lower seat mold base. During the injection molding raw material stage, it is avoided that the gap between the upper seat mold base and the lower seat mold base increases due to excessive pressure, and further the injection molding precision decreases, thus effectively ensuring good injection molding quality during the injection molding process.
