Specifically, the second core 21 can be arranged on a second supporting frame, and the second supporting frame can slide and rotate to drive the second core 21 to slide and rotate. The second core 21 can also be driven by a linear drive mechanism and a rotation drive mechanism to achieve sliding and rotation.

[0075] The molding box 3 is used to cooperate with the first cavity 12 and the second core 21 to mold the foaming layer 103. The molding box 3 includes a top plate 31, a bottom plate 32 and four side plates. The molding box 3 is open at both ends facing the first mold 1 and the second mold 2, and the first cavity 12 and the second core 21 can enter the molding box 3 through the openings at both ends of the molding box 3. The molding box 3 has a circle of limit plates 33, which are arranged on the surfaces of the top plate 31, the bottom plate 32 and the side plates facing the cavity.

[0076] The top plate 31 is provided with a foaming material feeding screw 34. The foaming material feeding screw 34 is connected to the top plate 31 through a bearing or connected to a bracket on the top plate 31. The foaming material feeding screw 34 is driven by a second rotation driving device, such as an electric motor, a motor, etc.

[0077] The foaming material feeding screw 34 has a third spiral channel for containing the material for making the foaming layer 103, and can convey the material in the third spiral channel to the bottom or inside of the top plate 31 by means of rotation. When the material for making the foaming layer 103 needs to be heated, the foaming material feeding screw 34 can be heated, or the heated material can be directly poured into the third spiral channel.

The second core 21 can be rotated 180° from the initial position and moved into the molding box 3, and finally sealed and contacted with the limiting plate 33, and the second core 21 is limited by the limiting plate 33. When the first cavity 12 and the second core 21 are both sealed and contacted with the limiting plate 33, a foam material molding cavity 30 is formed between the first cavity 12 and the second core 21, and the third feed channel 331 is connected to the foam material molding cavity 30, and the material for making the foaming layer 103 can enter the foam material molding cavity 30 through the third feed channel 331.

[0079] When the interior trim molding device is used to manufacture the interior trim 100, the operation steps are as follows:

[0080] The skin material particles are added to the skin material feeding screw 14 and heated to a first preset temperature (190°C-270°C), and the skin material particles are melted and injected into the mold cavity of the first core 11 and the first cavity 12 through the first feeding channel 111, and the temperature is lowered and allowed to stand for a first preset time until the skin layer 101 is formed. The first preset time can be set according to actual needs.

[0081] The skeleton material particles are added to the skeleton material feeding screw 24 and heated to a second preset temperature (190°C-300°C), and the molten skeleton material particles are injected into the second core 21 and the mold cavity of the second core 21 through the second feeding channel 221, and the temperature is lowered and the second preset time is left to stand until the skeleton layer 102 is formed. The second preset time can be set according to actual needs.

[0082] After the skin layer 101 is made, the skin layer 101 is adsorbed onto the first cavity 12 by the first adsorption device, and the first cavity 12 is opened. The first cavity 12 adsorbed with the skin layer 101 is rotated 180 degrees, and then moved into the molding box 3, and finally sealed with the limit plate 33.

[0083] After the skeleton layer 102 is made, the skeleton layer 102 is adsorbed onto the second core 21 by the second adsorption device, and the second core 21 is opened. The second core 21 adsorbed with the skeleton layer 102 is rotated 180 degrees, and then moved into the molding box 3, and finally sealed with the limiting plate 33.

[0084] Thus, a foaming material forming cavity 30 is formed between the skin layer 101 and the skeleton layer 102. The thickness of the foaming layer 103 can be achieved by adjusting the width of the limiting plate 33. The wider the width of the limiting plate 33, the wider the foaming material forming cavity 30 is, and the thicker the foaming layer 103 is. On the contrary, the foaming layer 103 is thinner.

[0085] The foaming material is injected into the foaming material forming cavity 30 through the foaming material feeding screw 34 and the third feeding channel 331, and is cooled and left to stand for a third preset time until the foaming layer 103 is formed. The third preset time can be set according to actual needs.

[0086] After the foaming layer 103 is formed, the foaming layer 103 is automatically bonded or integrally formed between the skin layer 101 and the skeleton layer 102 to form a blank of the interior trim.

[0087] The first cavity 12 and / or the second core 21 are opened, the interior trim blank is removed, and the first cavity 12 and the second core 21 are reset. The interior trim blank is cut to remove the redundant part, so as to form the required interior trim 100.

[0088] Therefore, the interior trim molding equipment provided by the present invention can use the first cavity 12 and the second core 21 to make the foaming layer 103, which saves the number of molding molds used, has high work efficiency, does not need to use glue to reduce environmental pollution, and the structure of the interior trim after molding is stable and reliable.

[0130] The foaming material is injected into the foaming material forming cavity 30 through the foaming material feeding screw 34 and the third feeding channel 331 , and is cooled and left to stand for a third preset time until the foaming layer 103 is formed.

[0131] After the foaming layer 103 is formed, the foaming layer 103 is automatically bonded or integrally formed between the skin layer 101 and the skeleton layer 102 to form a blank of the interior trim.

[0132] The first cavity 12 and / or the second core 21 are opened, the interior trim blank is removed, and the first cavity 12 and the second core 21 are reset. The interior trim blank is cut to remove the redundant part, so as to form the required interior trim 100.

[0137] Add skeleton material particles to the skeleton material feeding screw 24 and heat it to a second preset temperature (190°C-300°C), rotate the skeleton material feeding screw 24, inject the molten material of the skeleton material particles into the mold cavity of the second core 21 and the second cavity 22 through the second feeding channel 221, cool down and stand for a second preset time until the skeleton layer 102 is formed.

[0138] In one of the embodiments, the skin layer forming step and the skeleton layer forming step are performed simultaneously to improve production efficiency.

[0139] The synchronous execution referred to in this embodiment mainly refers to the simultaneous production of the skin layer 101 and the skeleton layer 102 , and does not mean that the operations are performed in the same steps, time, etc.

[0140] The thickness of the skin layer 101 can be controlled by the first core 11 and the first cavity 12 . The thickness of the skeleton layer 102 can be controlled by the second core 21 and the second cavity 22 .

[0141] As needed, the above technical solutions can be combined to achieve the best technical effect.
