[0003] The utility model aims at providing a kind of moulding tool that can collect and automatically overturn primer shell, can quickly collect 188 primer shells, and automatically overturn the primer shell with mouth part downward to mouth part upward, realize the predetermined requirement of 188 primer shells being all loaded into mould with mouth part in the attitude of being. UTILITY MODEL CONTENTS

[0004] The utility model provides a kind of automatic overturning primer shell moulding tool to solve the problem that primer shell needs manual placement in the attitude of being loaded into mould with mouth part upward in prior art.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An automatic overturning primer shell moulding tool, comprising horizontally placed lower plate, and upper plate arranged horizontally on the top surface of lower plate, the upper plate can slide horizontally on the top surface of lower plate, a plurality of upper plate holes vertically penetrating the upper plate are arranged in the upper plate, a plurality of vertical lower plate holes are arranged in the lower plate, the upper end of each lower plate hole is located on the top surface of lower plate, the position of each lower plate hole corresponds to the same direction side of each upper plate hole, and the horizontal straight line determined by the center of each upper plate hole and its corresponding lower plate hole is parallel to the horizontal straight line movement path of the upper plate.

[0007] Further, a waist-shaped hole is arranged in the upper plate, a positioning rivet is vertically installed in the waist-shaped hole of the upper plate, the lower end of the positioning rivet is riveted into the lower plate, and the cooperation of the waist-shaped hole and the positioning rivet limits the horizontal straight line sliding of the upper plate on the top surface of the lower plate.

[0008] Further, the diameter of each upper and lower through-hole is greater than or equal to the maximum outer diameter of a primer shell and less than 1.2 times the maximum outer diameter of a primer shell; the vertical axial height of each upper and lower through-hole is greater than or equal to the axial height of a primer shell and less than 1.2 times the axial height of a primer shell.

[0019] The utility model is further illustrated below in combination with the drawings and examples.

[0020] As Figure 2 , Figure 3 , Figure 4 , Figure 5 The embodiment discloses an automatic turnover primer shell dress mold tool, including horizontally placed lower overboard 2, and the upper overboard 1 of horizontal setting at the top surface of lower overboard.Overboard 1 can do the horizontal straight line sliding of X direction on the top surface of lower overboard 2.

[0021] In the embodiment, at least one waist type hole 1.2 is arranged at the X direction both sides edge position of upper overboard 1.2, the straight line edge of each waist type hole 1.2 is parallel to X direction, the straight line edge length of each waist type hole 1.2 is greater than or equal to the maximum outer diameter of a primer shell 4, each waist type hole 1.2 vertically penetrates upper overboard 1 respectively, and each waist type hole 1.2 is vertically penetrated and is installed with positioning rivet 3 respectively, and the lower end of each positioning rivet 3 is riveted into the corresponding position of lower overboard 2 respectively. Therefore, through the cooperation of waist type hole 1.2 and positioning rivet 3, the limiting is made, and upper overboard 1 can only do the horizontal straight line sliding of X direction on the top surface of lower overboard 2.

[0022] A plurality of upper overboard holes 1.1 vertically penetrating upper overboard are arranged in upper overboard 1, the hole diameter of each upper overboard hole 1.1 is greater than or equal to the maximum outer diameter of a primer shell 4, less than 1.2 times the maximum outer diameter of a primer shell 4, and the vertical axial height of each upper overboard hole 1.1 is greater than or equal to the axial height of a primer shell 4, less than 1.2 times the axial height of a primer shell 4. Therefore, each upper overboard 1.3 can only accommodate a primer shell 4 in a vertical state with the mouth upwards or the bottom upwards.

[0023] A plurality of vertical lower overboard holes 2.1 are arranged in lower overboard 2, the upper end aperture of each lower overboard hole 2.1 is located on the top surface of lower overboard 2, and the upper end aperture edge of each lower overboard hole 2.1 is respectively formed with an outwardly turned chamfer. The positions of the lower overboard holes 2.1 correspond to the positions of the upper overboard holes 1.1 in the same direction of X direction, so that the horizontal straight lines determined by the centers of each upper overboard hole 1.1 and its corresponding lower overboard hole 2.1 are parallel to X direction. The hole diameter of each lower overboard hole 2.1 is greater than or equal to the maximum outer diameter of a primer shell 4, less than 1.2 times the maximum outer diameter of a primer shell 4, and the vertical axial height of each lower overboard hole 2.1 is greater than or equal to the axial height of a primer shell 4, less than 1.2 times the axial height of a primer shell 4. Therefore, each lower overboard hole 2.1 can only accommodate a primer shell 4.

[0024] In the initial state, the upper plate 1 and the lower plate 2 are in a staggered position between the upper plate hole 1.1 and the corresponding lower plate hole 2.1, so that the primer shell 4 falls vertically into the upper plate hole 1.1 of the upper plate 1, and the lower plate 2 supports the primer shell 4 through the corresponding lower plate hole 1.1. At this time, part of the primer shell 4 in the upper plate hole 1.1 is in a position with the mouth upward, and part of the primer shell 4 in the upper plate hole 1.1 is in a position with the bottom upward.

[0025] As shown in Figure 6 , Figure 7 , in operation, the upper plate 1 is linearly slid in one direction along the X direction (leftward in Figure 6 , Figure 7 ), so that each upper plate hole 1.1 moves towards the corresponding lower plate hole 2.1. During the movement, the hole distance between the upper plate hole 1.1 and the lower plate hole 2.1 gradually decreases, and the chord length of the staggered part between the upper plate hole 1.1 and the lower plate hole 2.1 gradually increases.

[0026] At this time, the primer shell 4 in the upper plate hole 1.1 with the mouth upward begins to fall along the chamfer of the upper end of the lower plate hole 2.1 and falls into the lower plate hole 2.1, and continues to fall in the position with the mouth upward under the action of its own gravity. With the gradual decrease of the hole distance and the gradual increase of the chord length of the staggered part, the primer shell 4 with the mouth upward continues to fall into the lower plate hole 2.1 under the action of its own gravity and keeps the position with the mouth upward. Finally, when the upper plate hole 1.1 and the corresponding lower plate hole 2.1 coincide, the primer shell 4 with the mouth upward falls into the lower plate hole 2.1 in the position with the mouth upward.

[0027] The primer shell 4 in the upper plate hole 1.1 with the mouth downward does not change its position in the early stage of the sliding of the upper plate, and then turns over under the action of its own gravity when the hole distance gradually decreases and the chord length of the staggered part gradually increases to the diameter of the primer shell 4, and falls into the lower plate hole 2.1 in the position with the mouth upward. Finally, when the upper plate hole 1.1 and the corresponding lower plate hole 2.1 coincide, the primer shell 4 with the mouth downward falls into the lower plate hole 2.1 in the position with the mouth upward.

[0028] Therefore, in this embodiment, when the upper plate hole 1.1 and the corresponding lower plate hole 2.1 coincide, the primer shell in the upper plate hole 1.1 is in the position with the mouth upward, regardless of whether the primer shell is in the position with the mouth upward or the bottom upward. Further positioning design or device can be added on the lower plate to connect various charging molds and achieve the predetermined requirement that all the primer shells are in the position with the bottom downward.
