Description
Technical Field
The utility model relates to a pressurize smelting tool technical field specifically is a pressurize tool of hot pressing working of plastics.
Background
Along with the improvement of the manufacturing quality requirement of modern products, the surface flatness requirement of plastic part products is higher and higher, a considerable part of the existing plastic part products are plastic parts manufactured by a hot pressing method, the hot pressing plastic part is made of PC materials, the materials are heated to a melting point through hot pressing and then are molded through a mold to obtain the product, however, the hot pressing plastic part is generally a quick manufacturing product, the requirement on industrial shape change is higher, the manufacturing cost of the mold is relatively higher, generally, only one pair of normally produced molds are manufactured through one molding structure, therefore, the hot pressing plastic part must be quickly taken out from the mold after being molded to manufacture the next product, and due to the principle that the materials expand with heat and contract with cold, when the semi-finished product after being subjected to hot pressing is taken out and stored, the product naturally deforms in natural air, so that the quality of the surface flatness and the like of the hot pressing plastic part is reduced, so that the defective rate is high. Therefore, we propose a pressure maintaining fixture for hot pressing plastic parts.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pressurize tool of hot pressing working of plastics to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pressurize tool of hot pressing working of plastics, includes the base, the base top is provided with down the smelting tool, the smelting tool left and right sides is provided with the insulating layer down, the insulating layer top is provided with the smelting tool, it has pushing down the mechanism to go up the welding of smelting tool lower extreme, the base both sides are provided with the bracing piece, the fixed plate is installed on the bracing piece top, the fixed plate lower extreme is equipped with two electric putter, the electric putter bottom is connected go up the smelting tool.
Preferably, the four corners of the top of the lower jig are provided with positioning screws, and the positioning screws penetrate through the lower jig and are fixed in positioning screw holes in the bottom of the base.
Preferably, the top end of the lower jig is provided with a groove, and a corresponding semi-finished product is placed in the groove.
Preferably, the pushing mechanism is formed by welding two push rods and a pressing plate, and the two ends of each push rod are fixed to the bottom end of the upper smelting tool and the top end of the pressing plate respectively.
