Problems solved by technology

[0010] In theory, this method of heating with electric heating rods is feasible, but its disadvantage is that the heating speed is very slow (generally it takes about one hour to heat up to 200°C), and the heating is for the entire mold, so it cannot be targeted at a certain part of the mold. Partial heating of some parts has very limited effect in practice; in addition, after the injection is completed, the mold can only be opened when the mold is cooled to about 80°C (generally takes one hour), so this heating method is only used in Some special products are not widely used

Embodiment Construction

[0030] As shown in Fig. 1 and Fig. 2, the heating and cooling system of the injection molding machine of the present invention includes: a first clamping mold base 10, a first module 20, a second clamping mold base 30, a second module 40, a Heater 50 and a partition 60, wherein:

[0031] The inner surface of the first clamping base 10 is provided with a recess 11 for the first module 20 to be fixed, the interior is provided with a fluid pipe 12 surrounding the recess 11, the exterior is provided with a pipe joint 13 connected to the fluid pipe 12, and the pipe joint 13 When the cooling fluid is input into the fluid pipe 12 , the cooling fluid can perform heat exchange on the first module 20 on the first clamping base 10 . The outer surface of the first module 20 has a mold cavity space 21 of a predetermined shape. During implementation, the cooling fluid input by the fluid pipeline 12 may be cooling liquid or high-speed air flow.

[0032] The second clamping base 30 can be d...

Abstract

The present invention relates to one kind of heating and cooling system for injection molding machine. In the mold locking unit comprising one first mold seat and one second mold seat capable of being closed and opened, there are at least one heater set between the second mold seat and the second mold block and one fluid pipe inside the first mold seat. The heating and cooling system can heat and cool the mold fast, and this can eliminate faults of the molded product, reduce mold opening time and raise production capacity.

Description

【Technical field】 [0001] The invention relates to a heating and cooling system of an injection molding machine, in particular to a system capable of rapidly heating and cooling a mold. 【Background technique】 [0002] Press, plastic molding methods are divided into injection molding, blow molding, vacuum thermoforming, compression molding, extraction molding...etc. Among them, the shape of the plastic products that can be produced by injection molding ranges from simple cups to complex car dashboards, and the size ranges from 0.01g clock pinions to large-scale finished products such as bathtubs exceeding 20Kg. The advantages of complexity, precise size and stable quality are the most important and most commonly used technology among various plastic molding methods. The commonly used materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and ABS. [0003] The so-called plastic injection molding technology mainly uses the injection...
