Description

Technical Field

[0001] The present invention belongs to the technical field of two-color injection molding equipment, and particularly relates to a production equipment and a production process for two-color injection molding of an automotive center console visual panel. Background Art

[0002] Two-color injection molding refers to the use of two different types of plastics, and plastic products in which the two plastics can be clearly distinguished on the product are called two-color products. A mold that is installed on the same injection molding machine with two sets of injection molding devices (i.e., a two-color injection molding machine) and injects two plastics in sequence to produce a two-color product is called a two-color mold. Two-color injection molding is used in the production process of automotive center console visual panels. However, there are some problems with current injection molding equipment: 1. It is necessary to manually replace the position of the material, which is not safe and has a relatively low efficiency; 2. After the material is formed, it often adheres to the mold and is not easy to unload. Therefore, it is necessary to design a production equipment for two-color injection molding of an automotive center console visual panel. Summary of the Invention

[0003] The purpose of the present invention is to provide a production equipment and a production process for two-color injection molding of an automotive center console visual panel to solve the problems mentioned in the background art.

[0004] To solve the above problems, the present invention provides a technical solution:

The outer part of the top of the support column is threadedly connected with a threaded sleeve. A workbench is fixedly connected to the top of the threaded sleeve. Two symmetrically distributed columns are fixedly connected to the top of the workbench. A top plate is fixedly connected to the tops of the two columns. A cylinder is fixedly installed at the upper end of the top plate. A telescopic shaft is arranged on the cylinder. The telescopic shaft penetrates through the top plate and is slidably connected with the top plate. A pressing plate is fixedly connected to the bottom of the telescopic shaft. Two symmetrically distributed connecting blocks are fixedly connected to the pressing plate. A slider is fixedly connected to one end of each connecting block away from the pressing plate.

[0006] Preferably, the number of the support columns is four, and the four support columns are evenly distributed on the base.

[0007] Preferably, a slider is slidably sleeved outside each of the columns. A limiting ring is fixedly connected to the column. A first spring is sleeved outside the column. One end of the first spring contacts the slider, and the other end of the first spring is fixedly connected to the limiting ring. Two symmetrically distributed upper molds are fixedly connected to the bottom of the pressing plate. Two symmetrically distributed material cylinders are fixedly connected to the top of the pressing plate. An injection molding pipe is fixedly connected to the bottom of each material cylinder. The injection molding pipe penetrates through the pressing plate and the upper mold. A plurality of uniformly distributed arc grooves are formed in the workbench. A ball is arranged on each arc groove. The tops of a plurality of balls jointly contact a turntable.

[0008] Preferably, a connecting seat is fixedly connected to the bottom of the turntable. The connecting seat penetrates through the workbench and is rotatably connected to the workbench. A square clamping groove is formed inside the connecting seat. A motor is fixedly installed at the upper end of the base. A motor shaft is arranged on the motor. A connecting square column is sleeved outside the motor shaft. A first fixing bolt is slidably connected inside the connecting square column. The tail end of the first fixing bolt is threadedly connected to the motor shaft. The top of the connecting square column is clamped with the square clamping groove. A second fixing bolt is slidably connected inside the connecting seat. The tail end of the second fixing bolt is threadedly connected to the connecting square column.

[0009] Preferably, two symmetrically distributed lower molds are fixedly connected to the top of the turntable. The top of each lower mold contacts the upper mold. A material groove is formed in the lower mold. Two symmetrically distributed moving grooves are formed inside the lower mold. A guide rod is slidably connected inside each moving groove. A cushion block is fixedly connected to the top of the guide rod. Two symmetrically distributed sliding grooves are formed inside the lower mold. A cushion block is slidably connected inside each sliding groove. The sliding groove communicates with the moving groove. A connecting rod is jointly fixedly connected between the two guide rods. A wide groove is formed inside the lower mold. The connecting rod is slidably connected inside the wide groove. The two moving grooves communicate with the wide groove.

[0010] Preferably, a top rod is fixedly connected to the connecting rod. The top rod is slidably connected inside the lower mold.

[0011] Preferably, two symmetrically distributed extrusion blocks are fixedly connected to the bottom of the upper mold. The bottom of each extrusion block contacts the cushion block.

[0012] Preferably, a second spring is sleeved outside the guide rod. One end of the second spring is fixedly connected to the cushion block, and the other end of the second spring is fixedly connected to the inner surface of the sliding groove.

[0013] The production process of a production device for two-color injection molding of an automotive center control visual board specifically includes the following steps:

[0014] Step 1: When in use, open the cylinder. The telescopic shaft of the cylinder pushes the pressure plate downward. The pressure plate drives the two upper molds downward. At this time, the sliders on the two connecting blocks of the pressure plate slide downward on the two columns respectively, contact the first spring and compress the first spring;

[0015] Step 2: The pressure plate continues to descend, so that the upper mold contacts the lower mold to complete the mold closing with the lower mold. At this time, the extrusion block on the upper mold contacts the cushion block in the lower mold. The cushion block drives the guide rod downward and compresses the second spring. The guide rod drives the connecting rod downward, and the connecting rod drives the ejector rod downward, so that the top of the ejector rod remains flush with the material groove on the lower mold;

[0016] Step 3: At this time, the barrel on the left injects the first color into the material groove on the lower mold through the injection pipe. After the material cools, drive the cylinder to make the pressure plate drive the upper mold upward. Then turn on the motor. The motor drives the connecting square column to rotate. The connecting square column drives the connecting seat to rotate. The connecting seat drives the turntable to rotate on the ball bearings, so that the lower mold on the left and the lower mold on the right exchange positions. Then restart the cylinder to make the upper mold and the lower mold close the mold. Then the barrel on the right injects the second color into the material in the material groove through the injection pipe;

[0017] Step 4: After the second material color is injection-molded and cooled, drive the cylinder to make the upper mold leave the lower mold. At this time, the extrusion block also disengages from the cushion block. The second spring resets, so that the cushion block moves upward. The cushion block drives the guide rod upward. The guide rod drives the connecting rod upward. The connecting rod drives the ejector rod upward. The ejector rod pushes up the injection-molded material, and then the material can be taken away.

[0018] The beneficial effects of the present invention are as follows: The present invention relates to a production device and a production process for two-color injection molding of an automotive center control visual board, which has the characteristics of high efficiency, safety and reliability, and convenient material taking. In specific use, compared with the prior art, this production device has the following two beneficial effects:

[0019] First of all, the barrel on the left injects the first color into the material groove on the lower mold through the injection pipe. After the material cools, drive the cylinder to make the pressure plate drive the upper mold upward. Then turn on the motor. The motor drives the connecting square column to rotate. The connecting square column drives the connecting seat to rotate. The connecting seat drives the turntable to rotate on the ball bearings, so that the lower mold on the left and the lower mold on the right exchange positions. Then restart the cylinder to make the upper mold and the lower mold close the mold. Then the barrel on the right injects the second color into the material in the material groove through the injection pipe, without the need for manual material transposition, which is safe and reliable and improves efficiency at the same time;

[0020] Secondly, after the second material is injection-molded and cooled in the cold area, drive the air cylinder to separate the upper mold from the lower mold. At this time, the extrusion block also disengages from the cushion block, and the second spring resets, causing the cushion block to move upward. The cushion block drives the guide rod to move upward, the guide rod drives the connecting rod to move upward, and the connecting rod drives the ejector rod to move upward. The ejector rod pushes up the injection-molded material, facilitating the operator to take the material. BRIEF DESCRIPTION OF THE DRAWINGS
