TECHNICAL FIELD

[0001] The utility model relates to the technical field of injection molding, particularly to a copper bar injection molding sliding block. BACKGROUND

[0002] The new energy automobile industry is experiencing a rapid expansion stage. In recent years, the demand for copper bar injection molding products for new energy automobile applications has increased dramatically. Currently, when performing lateral core-pulling injection molding process for copper bar products, the common practice is to carve holes matching the copper bar on the sliding block, and to move the sliding block in a specific direction by driving elements to achieve core-pulling and demolding of the product.

[0003] However, within the existing technical framework, the connection end of the copper bar needs to be precisely placed in the hole of the sliding block before the injection molding operation begins. In reality, the insertion point of the copper bar often cannot be completely aligned with the center of the hole, which undoubtedly increases the risk of mold damage. SUMMARY

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. The utility model provides a copper bar injection molding sliding block, which reduces the risk of mold damage.

[0005] To achieve the above-mentioned purpose, the utility model provides a copper bar injection molding sliding block, which includes a sliding block body, a sliding block cover, and a driving element for driving the sliding block body to slide back and forth. The sliding block body is provided with an insertion slot extending along the sliding direction of the sliding block body. The end of the insertion slot away from the driving element has an insertion port. The insertion slot is provided with a cover opening, which is located on the side adjacent to the insertion port. The side of the sliding block cover facing the insertion slot is provided with a first magnet, and the side of the insertion slot facing the sliding block cover is provided with a second magnet. The sliding block cover is covered on the cover opening, and the first magnet and the second magnet are magnetically connected.

[0006] As a preferred scheme, the sliding block body includes a base and an insertion block. The insertion slot, the cover opening, and the insertion port are opened in the insertion block. The end of the insertion block away from the insertion port is connected with the base, and the driving element is in transmission connection with the base.

[0007] As a preferred scheme, the insertion block is provided with a magnetic attraction platform, which is located between the insertion slot and the sliding block body. The second magnet is arranged on the magnetic attraction platform. The sliding block cover includes a connecting plate and a cover plate. One end of the cover plate is connected with the connecting plate, the first magnet is connected with the connecting plate, the connecting plate is connected with the magnetic attraction platform, and the cover plate is covered on the cover opening.

[0009] The magnetic platform is provided with a second magnetic recess, the second magnet is connected in the second magnetic recess, and the upper end surface of the second magnet is flush with the magnetic platform.

[0010] When the slider cover is connected with the magnetic platform, the upper end surface of the insertion slot is flush with the magnetic platform, and the connecting surface is attached to the magnetic platform.

[0011] As a preferred solution, the insertion block is connected with a limiting block, the limiting block is located on the side of the magnetic platform facing the insertion slot, the limiting block protrudes from the magnetic platform and forms a clamping port, and the connecting plate is clamped in the clamping port.

[0012] As a preferred solution, the limiting block is defined as a first limiting block and a second limiting block, the extension directions of the first limiting block and the second limiting block are the same as the extension direction of the insertion slot, the first limiting block is connected on one side of the insertion slot, the second limiting block is connected on the other side of the insertion slot, the first limiting block and the second limiting block respectively form the clamping port at one end facing the magnetic platform, and the two ends of the connecting plate are respectively clamped in the clamping port.

[0013] As a preferred solution, a plurality of insertion blocks are provided, and the plurality of insertion blocks are connected to the base in parallel with the sliding direction of the base.

[0014] As a preferred solution, the lower end of the base extends downward to form a limiting portion for limiting cooperation with a lower mold.

[0015] As a preferred solution, the driving member is a hydraulic cylinder.

[0016] Compared with the prior art, the copper busbar injection molding slider of this utility model has the following advantages: the slider body is connected to the driving component, and the driving component drives the slider body to move towards or away from the injection cavity, thereby realizing core pulling and demolding of the product. The insertion slot is used to accommodate the connecting end of the copper busbar. The insertion slot has an insertion interface and a cover. The insertion interface faces the injection cavity. When the slider body moves away from the injection cavity, the connecting end of the copper busbar can be pulled out from the insertion interface. When the slider body moves to the injection position, the connecting end of the copper busbar can be directly inserted into the insertion slot from the cover, and the main body of the copper busbar can be inserted into the injection cavity from the insertion interface. After the copper busbar and slider body are secured, the slider does not need to move relative to each other for assembly before injection molding, thereby reducing the risk of mold damage. It also reduces the number of relative sliding operations between the slider and the connecting end of the copper busbar, reducing the risk of surface scratches on the connecting end of the copper busbar and improving product quality. After the copper busbar's connecting end is placed in the insertion slot, a first magnet is located on the side of the slider cover facing the insertion slot, and a second magnet is located on the side of the insertion slot facing the slider cover. After the first and second magnets are magnetically connected, the insertion slot and slider cover close, effectively surrounding the outer circumference of the copper busbar's connecting end. This operation is simple and efficient. Furthermore, the open structure of the insertion slot and slider cover facilitates processing and reduces manufacturing difficulty.
