Problems solved by technology

Existing plastic tables and chairs include two types, one is all made of plastic, this kind of plastic table and chair is made of plastic because the supporting legs are made of plastic, the load-bearing capacity of this product is very poor, and the plastic supporting legs are very easy to damage; One is the panel made of plastic material, the supporting feet made of iron or other hard materials, and then the two are fixed. After a period of use of this product, the panel often cannot be firmly connected with the hard supporting feet, which affects It is easy to scratch the user when it is used, and because the screws through the plastic panel are used to connect with the iron support feet, the screws on the surface of the seat are easy to scratch the user, and it is not beautiful at the same time
This structural defect causes the quality of existing plastic products to be low, which is also the reason why the grade of domestic plastic furniture products is not high.

Embodiment Construction

[0015] A preferred embodiment of the invention includes the following steps:

[0016] The present invention proposes a manufacturing method of plastic products. Firstly, the following steps are used to make the panels of the expected tables and chairs:

[0017] (1) Place the nut at an appropriate position on the mold;

[0018] (2) After the plastic is heated and melted in the extruder, it is extruded downward from the ring-shaped storage tank, and at the same time, the blower located in the center of the storage tank is blown downward to ensure that the extruded raw material is formed into a cylinder flow down;

[0019] (3) Clamp the mold to the middle;

[0020] (4) Insert the air needle from the male mold into the blank to inject air, so that the inner space of the plastic panel can be made, which saves materials and is light;

[0021] (5) Make use of mold pressure, air pressure, and cooling to cool and form the blank in the mold;

[0022] (6) Exhaust the air from the mol...
