Description

Simple production method of integrated plastic hollow ball pet toy

Technical field

The invention relates to a hollow ball pet toy, in particular to a preparation method of an integrated plastic hollow ball pet toy.

Background technique

With the continuous improvement of people's living standards, more and more people are starting to raise pets, especially pet dogs or pet cats. Pet toys are props that people use to play with pets, allowing pets to interact with their owners. Get up and increase your emotional communication.

Plastic rubber (TPR), also known as thermoplastic elastomer, is a material that combines the properties of rubber and thermoplastics. The thermoplastic elastomer has various possible structures, which exhibit rubber elasticity at normal temperature, and can be molded into a polymer material at a high temperature, and has mechanical properties and performance similar to those of rubber, and can be processed and recycled according to thermoplastics. It bridges between plastic and rubber. Plastic rubber (TPR) breaks the traditional boundary between rubber and plastic, and it is more economical and socially beneficial in terms of energy saving, labor saving and environmental pollution prevention.

At present, there are two methods for making a hollow ball on the market: one is a hollow ball cast with rubber, which is characterized by high cost, complicated process and long time required, and the market price is high due to the integrated integral ball; The second method is a hollow ball (two hemispheres) formed by plastic particles through an injection molding machine, which is characterized by low cost, simple process, and short time required. It is a ball formed by bonding or welding two hemisphere glues, but Its market price is low, so the competition is poor, and the ball is easy to break and the defective rate is high.

Summary of the invention

The object of the present invention is to solve the problem that the traditional rubber process is cumbersome and solve the problem that the existing two hemispheres for the hollow ball are combined and bonded, and a method for preparing the hollow ball pet toy with low cost and simple process is provided.

To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

The simple production method of the integrated plastic hollow ball pet toy, the injection molding process and the punching process are combined Combined, including the following steps:

(1) Making a spherical mother mold

Forming the mold of the hollow ball shape according to the sample drawing or the hollow toy ball, and engraving the concave and convex pattern of the hollow figure on the mold;

(2) Preparing toner

Prepare the toner according to the color required by the drawings or the toy ball, and prepare the raw materials including the toner and the plastic raw materials, mix them well and then add them to the hopper of the injection molding machine;

(3) Injection into a plastic parent ball

Open the injection molding machine and set the injection temperature. After the hollow-shaped mold is put on the machine, the injection molding is started, and the hollow parent ball is punched out;

(4) Die

Forming a pattern die for use in the punch press according to the pattern on the hollow ball parent;

(5) stamped products

The mother body of the hollow ball is placed on the die of the die, so that the pattern is aligned with the punch, and the punching press is started, and the finished product of the hollow ball can be made.

Further, the ratio of the plastic material to the toner of the step (2) is 1:1.

The injection temperature according to the step (3) is further preferably from 130 ° C to 150 ° C, and further, when it is a transparent material, the injection temperature is 135 ° C; when it is a color material, the injection temperature is 145 ° C.

The die process described in step (4) is as follows:

Press the pattern size on the hollow ball matrix, cut the die by wire cutting, divide the die and the punch; then grind the die to match the size of the die hole of the hollow ball as much as possible; then put the die into the punch and use the single Fix the die at the side, press it with the pressure plate, and fit the punch; finally adjust the stroke of the punch to make the die and the punch reach an optimal closed state.

Compared with the prior art, it has the following advantages:

The invention changes the cumbersomeness of the traditional rubber process, combines the two processes of the injection molding machine and the punching machine to produce the finished product, simplifies the process, shortens the production cycle, and reduces the production cost. The invention better solves the injection molding The machine can not realize the technical problem of the integrated hollow ball (only two hemispheres can be made, and then glued or welded with glue). According to the pattern of the hollow parent ball, different graphics can be changed (just modify the die graphic) A mother ball can make multiple patterns, and a variety of hollow balls make the product diversified.

detailed description

To facilitate an understanding of the invention, the invention is set forth below. It should be understood by those skilled in the art that the present invention is only to be construed as a

The simple production method of the integrated plastic hollow ball pet toy combines the injection molding process with the punching process, which mainly includes four steps: the first step is to make a spherical mother mold; the second step is to injection into a plastic mother ball; the third step is to make a hollow The punch of the pattern; the fourth step is punching the punch.

The whole production process is: engraving the hollow ball matrix injection mold - modulating the desired color of the finished product and mixing the plastic TPR particles - injection molding the spherical matrix - strong demoulding - using a good punch on the punch - rushing out Shaped holes in the hollow pattern - inspection - finished packaging - finished products.

The ratio of the use of plastic raw materials and toner in the above process is 1:1;

Among them, the injection molding process is as follows:

Use a drying hopper to allow the prepared raw materials (dyed plastic particles) to dry sufficiently in the hopper;

The injection temperature is set between 130-150 ° C, (transparent material is 135 ° C, the color material is 145 ° C), and the temperature is moderately adjusted according to the state of the product;

Adjust the pressure and the flow rate of the glue, and directly hit the parent ball without quality problems;

The mold is released by a steam gun, and the inner core (insert) of the ball body is taken out to form a mother body of the hollow ball.

Among them, the die process is as follows:

Pressing the pattern size on the hollow ball matrix, cutting the die by wire cutting, dividing the die and the punch;

Grinding the die to match the size of the knockout hole of the hollow ball master as much as possible;

Put the die into the punching machine, and fix the die with a single side, press it with a pressure plate, and fit the punch;

Adjust the stroke of the punch to make the die and punch reach an optimal closed state.

The process of the invention is simple to manufacture, and combines the process of the injection molding machine and the punching machine to change the traditional rubber manufacturing process, and also changes the problem of the traditional bonding of the hollow balls with the two hemispheres, which greatly shortens the production time. And it highlights the integrity of the product, truly realizes the integration of products, and the production cost is low.
