Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to barrel cooling blocks, in particular to a barrel cooling block. Background Art
[0002] Injection molding machine, also known as injection molding machine or injection machine, is a main molding equipment that uses plastic molding molds to make plastic products of various shapes of thermoplastic plastics or thermosetting plastics. Before the plastic products are molded in the mold, the plastic pellets need to be heated and melted first, and then injected into the mold through the barrel.
[0003] The barrel cooling block is used to cool the plastic raw materials at the end of the barrel and the discharge hole of the injection molding machine, so as to prevent the raw materials from heating up, softening and solidifying into blocks, thereby blocking the discharge hole. In the prior art, the barrel cooling block is generally cast from ductile iron and then machined. Figure 5 and Figure 6 As shown, the cooling water channel 6 is typically drilled with multiple holes on a drilling machine, which are then connected to form a circulating water channel. However, this structure often has the following shortcomings: First, drilling multiple holes on a drilling machine is cumbersome and wastes processing time. Second, in addition to the water inlet 4 and the water return port 5, the redundant intersections after drilling need to be blocked with plugs 7, which is cumbersome and not conducive to cost savings. Third, because the holes drilled by the drilling machine are mostly linear, the distance from the entire cooling water channel 6 to the barrel mounting hole 2 is uneven, resulting in uneven cooling effect. Finally, the water channel cross-sectional area processed by this method is small, resulting in a small water flow rate and poor cooling effect. Utility Model Content
[0004] The utility model aims to overcome the shortcoming of poor cooling effect of the cooling water channel on the barrel cooling block in the prior art and provides a barrel cooling block which is beneficial to improving the cooling effect.

The shape and position design of the cooling water channel ensures a uniform distance from the entire cooling water channel to the barrel mounting hole, thereby achieving a more uniform cooling effect and improving the cooling effect.
[0009] Preferably, the discharge hole is perpendicular to the barrel mounting hole, one end of the discharge hole is located on the side wall of the barrel mounting hole and is connected to the barrel mounting hole, and the other end of the discharge hole is located on the top side of the cooling block body and is in an outwardly expanding trumpet shape, which facilitates rapid discharge of materials from the discharge hole and reduces the risk of clogging of the discharge hole.
[0010] Preferably, the cross-sectional shape of the cooling water channel is square, and the cross-sectional shape and size of the water inlet and the water return port are the same as the cross-sectional shape and size of the cooling water channel.
[0011] As another preferred embodiment, the cross-sectional shape of the cooling water channel is circular, and the cross-sectional shape and size of the water inlet and the water return port are the same as the cross-sectional shape and size of the cooling water channel. The cross-sectional shape of the cooling water channel is not limited by the above two solutions and can be set according to actual needs.
[0012] The beneficial effects of the utility model are as follows: the cooling water channel of this structure is directly cast, with beautiful appearance, light weight, simple processing, and reduced processing time; no plug is required, which is beneficial to cost saving; at the same time, the annular water channel has a large cross-sectional area and a large water flow rate, which achieves the purpose of improving the cooling effect; the cooling water channel surrounds the barrel mounting hole and is located on the side of the discharge hole, which can cool the barrel mounting hole and the discharge hole at the same time to avoid blockage of the discharge hole; the shape and position design of the cooling water channel makes the distance from the entire cooling water channel to the barrel mounting hole uniform, thereby making the cooling effect more uniform and improving the cooling effect.
