Abstract

The utility model relates to a heat molding machine group structure. The utility model at least comprises a mold unit, a heating unit, a cold air moisture removing box, a temperature sensing unit, etc., wherein the mold unit has proper containing space for the injection of raw materials, the mold unit is driven by a rotating seat and the heating unit can heat molds indirectly. The temperature sensing unit monitors any three positions of the mold unit, the temperature difference is enabled to be in certain temperature, the cold air moisture removing box is matched to provide dehumidification after raw materials are ejected for the mold unit and raw materials can obtain perfect crystallization at the time of drying and molding.

Description

Thermoforming unit structure

Technical field

The utility model provides a kind of thermoforming unit structure, refers to especially a kind ofly (for example be applied to the plastic hinge material; Material such as plastics, acryl) thermoforming technology can make this plastic hinge material after the moulding of this thermoforming unit, have better transparency, and mould zygonema, bubble, impurity and slight crack all is able to tangible reduction.

Background technology

In the general daily living article, the bright shape plastic body of relevant hollow is extensively applied on various machines (device) tool; For example: lampshade, decorate bottle, fish jar, packing box etc., its quality with light weight, intensity is good, transparency is high, ganoid product is the best; And the facility of known this kind of manufacturing product, mainly be to be provided with a mould, the periphery of this mould is provided with heating unit, after then the plastics that melt with heat inject this mould, can wait its cooling and moulding gradually, give form removal again and take out manufactured goods, because the heating unit of these facility directly is located in the mould, heating source is for fixing, caused some position temperature of plastics higher, and the temperature of some position is lower, makes the speed inequality of its cooling, therefore in crystallization, will produce fine fisssure, be easy to generate bubble and impurity simultaneously and gather, and the light transmittance after the moulding is not good, when the plastics of moulding approach at a place, even can produce the phenomenon of breaking, therefore generally can only make the bigger housing of thickness.

Summary of the invention

Main purpose of the present utility model is to provide a kind of thermoforming unit structure, and this thermoforming unit structure can be allocated uniform temperature.

This thermoforming unit structure includes at least:

One die unit, this die unit has suitable spatial accommodation, in this die unit bottom or a side be provided with and can drive the rotating seat that this die unit is done rotation;

One heating unit is located at the outside of die unit, and mould is done indirect heating;

One temperature-sensitive unit can be monitored wantonly 3 positions of die unit, and cooperates heating unit to do heating, and the temperature difference is dropped in certain temperature;

One cold air removes wet tank, and the dehumidifying of die unit after stock penetrates is provided, and makes this die unit can obtain more perfect crystallization at follow-up drying forming.

Die unit is provided with electrodeposited coating in inner wall.

The temperature-sensitive unit to wantonly 3 position temperature difference of die unit in two degree Celsius.

This heating unit is bestowed indirect from a plurality of directions of die unit, outer rim at this mould then is provided with via computer-controlled temperature-sensitive unit, mould is heated uniformly, after material feeding is finished, again mould is inserted cold air and remove moisture content, give even heating, drying again and moulding, can obtain thin shelly plastic product except that in the wet tank, and its transparency is preferable, and mould zygonema, bubble, impurity and slight crack all are able to effective improvement.

The specific embodiment

Please referring to shown in Figure 1, thermoforming unit of the present utility model includes die unit 10, heating unit 30, cold air at least except that wet tank 20, temperature-sensitive unit 40; Please cooperate referring to Fig. 1, shown in Figure 2, this die unit 10 has suitable spatial accommodation 11 again, and the edge wall is provided with electrodeposited coating 12 within it, is provided with rotating seat 50 in these die unit 10 bottoms or a side again, can drive die unit 10 and rotate.

Heating unit 30 is located at the outside of die unit 10, and mould is done indirect heating (for example hot air type heating); And wantonly 3 positions that are able to the 40 pairs of die units 10 in temperature-sensitive unit monitor, and make the temperature difference in two degree Celsius.

Cold air removes wet tank 20 dehumidifying of die unit 10 after stock 60 penetrates is provided, and makes this die unit 10 can obtain more perfect crystallization at follow-up drying forming.

Because design of the present utility model has clever thought, has all following advantage on the implementation:

1. because die unit inwall of the present utility model is provided with electrodeposited coating, the chamfering slit in the mould is filled and led up,, be made the surface of product more smooth so the mould zygonema is more hiding.

2. remove wet tank because the utility model is provided with cold air, after penetrating mould,, can effectively subdue the cohesion of the bubble and the impurity of stock moisture removal.

3. because the utility model is provided with the temperature automatically controlled temperature-sensitive unit of tool, match, can make the stock heating temperature more even, also be difficult for producing breaking so both made to take shape in than thin housing with heating unit.

Claims

1. thermoforming unit structure is characterized in that including at least:

One heating unit is located at the outside of die unit;

One temperature-sensitive unit, wantonly 3 positions of supervision molding unit;

One cold air removes wet tank, and die unit penetrates the back at stock and removes the wet tank dehumidifying by cold air.

2. thermoforming unit structure as claimed in claim 1, it is characterized in that: die unit is provided with electrodeposited coating in inner wall.

3. thermoforming unit structure as claimed in claim 1 is characterized in that: the temperature-sensitive unit to wantonly 3 position temperature difference of die unit in two degree Celsius.
