Problems solved by technology

[0002] Most of the plastic model bodies produced by the production method of plastic models in the prior art have parting lines. This is because the production molds are mostly split structures, generally comprising two split bodies. Plastic material is added to the mold, and after cooling, the two molds are separated and demoulded. Due to the insufficient precision of the mold, the two parts cannot be closely matched, so when demoulding, there will be plastic between the two molds due to loose fit. To fill the gap, and leave a seam line on the plastic body after demoulding. Due to the existence of this seam line, the appearance of the plastic model is not beautiful and affects the viewing effect. Therefore, a manufacturing method is developed to produce no seam line of models become technical problems that model makers need to solve

Embodiment 1

[0030] Embodiment 1: refer to figure 1 , a production method of plastic model, it comprises the following steps:

[0031] (1) Mixing equipment is set: mixing kettle 11, water removal kettle 22, coloring kettle 44, coloring kettle 55 and coloring kettle 66 are set at different positions successively, and water removal kettle 22 is combined with mixing kettle 11 and three The coloring kettles are connected through pipelines, and the water removal kettle 22 and several coloring kettles are also connected with the vacuum pump 33 through pipelines, valve 1, valve 2, valve 3, valve 4, valve 5, valve 6, valve 8 , valve 9, valve 41, valve 51 and valve 61 are respectively arranged on each connecting pipeline, and when the device is not activated, each valve is in a closed state, and the lower end of each coloring kettle is provided with a discharge port;

[0032] (2) Weighing: take raw materials according to the formula shown in the second column of Table 1;

[0033] (3) Mixing: put ...

Embodiment 2

[0044]Embodiment 2: The production method of the plastic model provided by this embodiment and the products thereof are basically the same as in Embodiment 1, the difference being that in step (2), the ratio of each raw material is as shown in the third column of Table 1, In step (9), the weight ratio of potassium nitrate to sodium nitrite is 1:1.

Embodiment 3

[0045] Embodiment 3: The production method of the plastic model provided by this embodiment and its products are basically the same as in Embodiment 1, except that in step (2), the ratio of each raw material is as shown in the fourth column of Table 1, In step (9), the weight ratio of potassium nitrate to sodium nitrite is 1:1.2.

[0046] The present invention is not limited to the above-mentioned embodiment, according to needs, can also be provided with coloring kettles loaded with other color pastes in sequence, and the setting of its valves and pipelines is similar to the setting of other several coloring kettles; if it is necessary to prepare thicker For the model, steps (10) and (11) can be repeated many times until the required thickness is reached; plastic products with different softness and hardness can be prepared by adjusting the ratio of each formula raw material; according to actual needs, multiple products can also be prepared. The plastic simulation model of a k...

Abstract

The invention provides a method for producing plastic models. The method comprises the following steps of (2) weighing, (3) mixing, (4) coloring, (5) reclaiming materials, (6) setting a salt groove and a flume, (7) putting a mold filled with slurry into the salt groove so as to be heated and finalized, (8) releasing the mold and (9) cutting off leftover materials, so as to obtain a plastic model. The method for producing plastic model products has the advantages of simple process, convenient operation, strong repeatability and convenience for forming scale production. As an evacuating-dewatering process is added to production course, moisture contained in plastic simulation model materials is effectively removed. In addition, as the method is simple in used equipment and especially reduces the cost for the mold by nearly 3 times, the method is beneficial to the large-scale popularization and application. The invention also discloses a product adopting the method. The product is smooth and clean in surface and has no parting line, thereby effectively ensuring the appearance reality sense of simulation products.

Description

technical field [0001] The invention relates to plastic technology and products, in particular to a production method and products of a plastic model, such as a production method and products of a plastic simulation head, a plastic simulation hand and a plastic simulation shoe model. Background technique [0002] Most of the plastic model bodies produced by the production method of plastic models in the prior art have parting lines. This is because the production molds are mostly split structures, generally comprising two split bodies. Plastic material is added to the mold, and after cooling, the two molds are separated and demoulded. Due to the insufficient precision of the mold, the two parts cannot be closely matched, so when demoulding, there will be plastic between the two molds due to loose fit. To fill the gap, and leave a seam line on the plastic body after demoulding. Due to the existence of this seam line, the appearance of the plastic model is not beautiful and af...
