Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a special injection platform front plate with a double-screw structure. Background Art

[0002] The injection support structure is an important component of the existing injection molding machine, which includes a front plate of the shooting platform, which is connected to the rear plate of the shooting platform through an injection tie rod and supports the placement of the screw.

[0003] The structure of the shooting platform front plate of some three-plate injection seats can refer to the Chinese patent announcement number CN206598451U, which discloses a shooting platform front plate structure of an injection molding machine, including a shooting platform front plate, a positioning hole for the barrel screw to pass through is provided in the center of the shooting platform front plate, and shaft holes for installing the screw bearing seat are symmetrically provided on both sides of the positioning hole on the shooting platform front plate.

[0004] In the above structure, the axial hole of the front plate of the shooting platform is located in a cylinder, and the cylinder is integrated with the front plate of the shooting platform. Although this design can save materials, it also leads to the problem of poor overall strength performance. In order to pursue sufficient strength, some manufacturers adopt the method of directly punching holes in a whole material to produce the front plate of the shooting platform, which leads to serious material waste and the product is relatively rigid and bulky. Utility Model Content

[0005] Aiming at the shortcomings of the existing shooting platform front plates that are either rigid and bulky or insufficient in strength, the utility model provides a special shooting platform front plate with a double-screw structure which has sufficient strength and reduced weight.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A front plate of a shooting platform specially used for a double-screw structure comprises a front plate body, a positioning hole located at the center of the front plate body for passing a barrel screw, and axial holes located on both sides of the positioning hole for installing a screw bearing seat, a mounting hole for passing an injection guide rod is arranged obliquely above the axial hole, and a weight-reducing structure for reducing weight while ensuring strength is arranged on the front plate body, the weight-reducing structure comprises a first weight-reducing arc groove which is recessed in the direction of the positioning hole at the bottom of the front plate body and has two ends extending in the length direction of the front plate body, a first weight-reducing groove is recessed downward on the upper end surface of the front plate body, and the bottom of the first weight-reducing groove is in an arc shape which is concentric with the positioning hole and convex upward.

[0008] By adopting the above scheme, a weight-reducing structure is opened on the integrated structure to save materials. The weight-reducing structure needs to ensure sufficient strength while saving materials. A first weight-reducing arc groove is set at the bottom of the front plate body, and the arched anti-deformation performance is used to ensure the longitudinal anti-deformation performance of the front plate body. A first weight-reducing groove is opened at the upper end of the front plate body, and the bottom of the first weight-reducing groove is set to a convex arc shape. While ensuring the anti-deformation performance, as much excess material as possible can be dug out to achieve lightweight. The above-mentioned weight-reducing structure can save some materials to a great extent and ensure sufficient strength and anti-deformation ability.

[0009] Preferably, the first weight-reducing arc groove is divided into a deep arc groove in the middle and shallow arc grooves on both sides whose depth is lower than the deep arc groove along the thickness direction of the front plate body, and the curvature of the shallow arc groove is greater than that of the deep arc groove.

[0010] The above scheme adopts a weight-reducing structure that combines deep and shallow arcs, which reduces weight while ensuring sufficient strength.

[0011] Preferably, the upper end surface of the front plate body is symmetrically provided with second weight-reducing grooves on both sides of the first weight-reducing groove, and the bottom of the second weight-reducing groove is in an arc shape which is concentric with the shaft hole and convex upward.

[0012] By adopting the above solution, the second weight-reducing groove is provided to further reduce the material consumption, and the arc shape of the groove bottom is used to retain sufficient anti-deformation performance.

[0013] Preferably, third weight-reducing grooves are provided on both sides of the front plate body, and the bottom of the third weight-reducing groove is in an arc shape which is concentric with the shaft hole and convex outwards.

[0014] By adopting the above solution, the provision of the third weight-reducing groove further reduces the material consumption, and the curvature of the groove bottom can also ensure sufficient anti-deformation performance.

[0015] Preferably, a second weight-reducing arc groove is recessed at the bottom of the front plate body along the thickness direction of the front plate body.

[0016] By adopting the above solution, the second weight-reducing arc groove is provided to further reduce the material consumption, and the arch shape is utilized to ensure sufficient anti-deformation performance.

[0017] Preferably, the bottom of the front plate body is symmetrically recessed with a fourth weight-reducing groove on both sides of the deep arc groove, the bottom of the fourth weight-reducing groove is an arc shape that is concentric with the shaft hole and convex downward, and the fourth weight-reducing groove is connected to the second weight-reducing arc groove.

[0018] By adopting the above solution, the provision of the fourth weight-reducing groove further reduces the material consumption and retains sufficient anti-deformation performance.

[0019] The utility model has significant technical effects due to the adoption of the above technical scheme: a weight-reducing structure is provided on the integrated structure, and the first weight-reducing arc groove, the second weight-reducing arc groove and the fourth weight-reducing arc groove at the bottom of the front plate main body are used to ensure that the lower part of the front plate main body is as lightweight as possible while retaining sufficient anti-deformation performance; the first weight-reducing groove, the second weight-reducing groove at the upper end of the front plate main body and the third weight-reducing groove on both sides are used to further reduce the weight of the front plate main body and ensure sufficient anti-deformation performance. The shooting platform front plate significantly reduces the weight and material while retaining sufficient anti-deformation performance, thereby realizing lightweight production.
