Problems solved by technology

At present, the cribs on the market are only made of iron and wood. Each crib produced by iron and wood requires at least dozens of processes. It needs to be produced separately) consumes a lot of natural resources and human resources. Iron cribs are easy to rust, corrode, paint off, heavy and conductive, etc. In addition, they are too stiff and cold to give people a cold feeling. Different densities cause the overall strength of the crib to be insufficient, difficult to maintain, flammable, perishable, easy to mold, intolerant to insects, shrinking when dry and swelling when wet, etc. In addition, the mortise of the crib often falls off due to shrinkage and swelling and mortise cracking, etc. cause safety hazards

Embodiment 1

[0016] The first step: design the crib style. Let's take the simplest crib as an example. The simplest crib consists of five large parts: two headboards, two side rails and a bed board.

[0017] The second step: according to the designed crib style, five foaming molds are developed based on the shapes of five large parts.

[0018] Step 3: Place the developed five foaming molds around the foaming machine in turn (for the convenience of description, they are called a.b.c.d.e in sequence) to form a circle around the foaming machine (the discharge head of the foaming machine can rotate around). Water temperature heating or electric heating technology allows the mold to preheat to about 25-35 degrees. The specific temperature is set differently depending on the indoor temperature of the factory building. In winter, the temperature should be set higher at about 35 degrees, and in summer it should be set at about 25 degrees. (When heating with water temperature, a water temperature...

Embodiment 2

[0025] In the embodiment of the present invention, plastic is raw material to make crib

[0026] The first step: design the crib style. Let's take the simplest crib as an example. The simplest crib consists of five large parts: two headboards, two side rails and a bed board.

[0027] Step 2: According to the designed crib style, five injection molds are developed based on the shapes of five large parts.

[0028] Step 3: Install the developed five foaming molds in five injection molding machines in sequence.

[0029] Step 4: Add the pellets into the barrel (each feeding should be quantitative to ensure uniform plasticization), heat and melt, (the operation process of each injection molding machine below is the same)

[0030] Step 5: Injection and pressure maintenance. The injection molding machine uses a screw to inject the molten plastic into the cavity (after the injection, keep the pressure on the molten plastic for a certain period of time).

[0031] Step 6: Keep cooling...

Abstract

The invention discloses a manufacturing method of a crib. The manufacturing method includes the following steps that corresponding molds are designed according to components of the crib, the components of the crib comprise two side bars, two bedsides and a bed board, the components are arranged linearly, the molds are opened, the temperature of the molds ranges from 25 DEG C to 35 DEG C, the raw materials are injected into the molds, the molds are combined and stand still for 9 minutes to 11 minutes, then the molds are opened, the components, formed in the molds, of the crib are taken out, the two bedsides and the two side bars are fixed through screws, and the crib is obtained after the bed board is mounted. According to the manufacturing method, a wood-imitation material or plastic is adopted, and the crib has the beneficial effects of being free of rust, resistant to corrosion, low in mass, insulating, balanced in density distribution, good in compressive strength, good in dimensional stability, free of cracking, free of maintenance, resistant to flame, free of mildew, long in service life, environment-friendly, free of pollution to the surroundings, free of consumption of a great number of natural resources, good in water resistance and high in safety coefficient.

Description

technical field [0001] The invention relates to the field of daily necessities for babies, in particular to a method for making a crib. Background technique [0002] A crib refers to a bed for infants and young children. There are many styles of cribs nowadays, and the functions and prices are also very different. When choosing, you should pay attention to the principle of combining safety and practicality. At present, the cribs on the market are only made of iron and wood. Each crib produced by iron and wood requires at least dozens of processes. It needs to be produced separately) consumes a lot of natural resources and human resources. Iron cribs are easy to rust, corrode, paint off, heavy and conductive, etc. In addition, they are too stiff and cold to give people a cold feeling. Different densities cause the overall strength of the crib to be insufficient, difficult to maintain, flammable, perishable, prone to mold, intolerant to insects, shrinking when dry and swelli...
