Problems solved by technology

[0003] At present, most injection molding machine production workshops use one water supply pump or use two to several water supply pumps in parallel to provide cooling circulating water to each injection molding machine in the injection molding workshop at the same time. It often happens that the power of the water supply pump is too small, or the pipeline The deviation of resistance causes insufficient cooling water flow of the injection molding machine far from the water supply pump, resulting in the hydraulic oil in the hydraulic system of the injection molding machine not being cooled in time, resulting in machine failure, or when the oil temperature of the hydraulic oil exceeds 55 degrees Celsius, The electrical control system of the injection molding machine with temperature protection enters the protection state and stops
In addition, if the injection mold is not cooled by the circulating cooling water in time, the cooling time of the production process will be prolonged and the production efficiency will be reduced, and the plastic products produced will be defective or even scrapped.
[0004] If a high-power, high-flow water supply pump is used in actual production, the energy consumption will be too large and the production cost will increase. Especially when only one or a few injection molding machines are working in the workshop, a high-power water supply pump needs to be operated, resulting in energy consumption. waste
As for the advanced frequency conversion control circulating water supply system, due to the high price of the frequency conversion system, the high technical requirements for the maintenance of the electrical control system, and the heavy burden on small and medium-sized enterprises, it is seldom used at present.

Embodiment 1）

[0035] see figure 1 The cooling water circulation system of the injection molding workshop of this embodiment includes a reservoir, a cooling water circulation pipeline, a cooling tower 4 and a supplementary water supply pipeline 51.

[0036] The reservoir includes a pool body 1. The pool body 1 includes a pool wall 11, a pool bottom 12 and a partition wall 13, the bottom end of the partition wall 13 is fixed on the pool bottom 12, and the height of the partition wall 13 is the same as the height of the pool wall 11. The 1 / 2 to 2 / 3 part of the pool body 1 is located below the ground 6, and the remaining part is located above the ground 6, which not only ensures sufficient water storage, but also covers a small area; in this embodiment, the upward direction of the pool body 1 The height of the part protruding from the ground 6 is 1200 mm, and the depth of the part below the ground 6 is 2000 mm.

[0037] The tank body 1 is divided into two parts by a partition wall 13, which are a s...

Embodiment 2）

[0057] The rest of this embodiment is the same as the first embodiment, except that it also includes a replenishment pool, a water pumping pipe, a replenishment water pump, a miniature limit switch 52 and a float 53. The miniature limit switch 52 controls the opening and closing of the make-up water pump. The figure does not show the make-up tank, the pumping pipe and the make-up pump.

[0058] The inlet of the make-up water pump is connected with the pumping pipe, the lower part of the pumping pipe is vertically arranged, and the lower port extends into the lower part of the replenishing pool. The water outlet of the makeup water pump is connected to the water inlet of the supplementary water supply pipe 51. The floating ball 53 floats in the water supply tank 2, and the upper part of the floating ball 53 is connected to the swing rod of the miniature limit switch 52 through a wire. When the water level in the water supply tank 2 drops, the floating ball 53 drops accordingly, ...

Embodiment 3）

[0061] see figure 2 The rest of this embodiment is the same as in embodiment 1, except that: the return water pipeline 8 also includes a first discharge pipe 82, a second discharge pipe 83, a second backwater discharge gate valve 85 and a third backwater discharge gate valve 86. The proximal end of the return water main pipe 81 is connected to the water inlet of the first discharge pipe 82 and the water inlet of the second discharge pipe 83 through corresponding three-way joints. The first discharge pipe 82 is connected to the water inlet pipe 41 of the cooling tower 4 through a second backwater discharge gate valve 85. The water outlet of the second discharge pipe 83 is located above the backwater sedimentation tank 3, and the third backwater discharge gate valve 86 is connected in series on the second discharge pipe 83.

The cooling water circulation pipeline comprises a water inlet pipeline, a return water pipeline and cooling branches connected between the water inlet pipeline and the return water pipeline, each cooling branch comprises a subsidiary water inlet pipeline, a water pump, a heat exchanger and a subsidiary return water pipeline sequentially, a subsidiary water inlet of the water inlet pipeline of each cooling branch is connected onto a main water inlet pipeline, a water outlet of the subsidiary return water pipeline is connected onto a main return water pipeline, and the water pump is arranged between a water outlet of the subsidiary water inlet pipeline and a water inlet of the exchanger. Each injection molding machine is equipped with a water supply pump, so that one or more injection molding machines can be started according to requirements of enterprises by starting the water supply pumps for the corresponding injection molding machines.

Description

Technical field [0001] The invention relates to a cooling water circulation system used in an injection molding workshop. Background technique [0002] In the injection molding workshop, circulating cooling water plays a very important role. It is mainly supplied to the chiller, injection molding machine oil cooler and barrel cooler for heat exchange (these devices can all be called heat exchange from the perspective of heat exchange) Device) to meet the temperature control requirements of the injection molding process and ensure the normal operation of the injection molding machine hydraulic system. In order to reduce the energy consumption of the system, a reasonable design of the cooling water circulation system in the injection molding workshop is essential.
