Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to an egg box injection mold. Background Art
[0002] The main function of an egg box is to protect the safety of eggs during handling and transportation, and to improve the convenience of storage and carrying. At the same time, its unique design also makes it more practical in daily life. An egg box currently available on the market mainly consists of an upper shell and a lower shell. The two parts are integrally formed on one side, while the other side is detachably connected through a clever snap-on design. The snap-on includes a snap-on protrusion and a snap-on hole that matches the snap-on protrusion. In actual production, an insert is set at the corresponding position of the mold, and the insert protrudes inwardly from the molding cavity of the mold to realize the molding of the snap-on hole. In the production process of the existing egg box, due to the structural problem of the mold, the drainage speed is slow and the drainage time is long, thereby prolonging the production time, and causing the slurry to be deposited at the bottom of the product, resulting in uneven thickness of the product.
[0003] In order to solve this problem, the existing injection mold needs to be improved to solve the problem of slow drainage, thereby improving production efficiency and product quality. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and provide an egg box injection mold.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An egg box injection mold comprises a fixed mold and a movable mold which can be molded together. The fixed mold comprises a template and a first molding area, a first drainage hole and a second drainage hole arranged on the template. The movable mold is provided with a second molding area corresponding to the first molding area, so that the movable mold and the fixed mold jointly form a molding cavity after the molds are molded together. The first drainage holes are evenly distributed in the first molding area and penetrate the template longitudinally. The second drainage holes are designed to correspond to the shape and position of the clamping hole of the egg box and penetrate the template horizontally.
[0007] The egg box injection mold of the utility model eliminates the insert at the position of the clamping hole and provides a corresponding drainage hole. When water flows out through the second drainage hole, the corresponding part in the mold will not be filled with material, thereby forming a hollow clamping hole on the final formed egg box. Compared with the prior art, the utility model adopts a second drainage hole to replace the insert design to realize the forming of the egg box clamping hole. The second drainage hole can assist in draining the water in the first molding area, thereby improving the drainage efficiency, shortening the drainage time, and avoiding the problem of slurry deposition at the bottom of the product due to long drainage time. In addition, the utility model is aimed at the mold design in the production process, and does not change the design of the egg box itself, so users can still enjoy the original convenience when using the egg box.
[0008] Furthermore, the fixed mold further includes a filter screen and a screen pressing frame, the first molding area is located at the inner side of the upper end of the mold plate, the filter screen is attached to the surface of the first molding area, and the screen pressing frame presses the filter screen against the first molding area. The filter screen of this solution plays a filtering role, filtering out water and allowing the slurry to adhere to the mold surface; at the same time, the screen pressing frame presses the filter screen against the first molding area, ensuring the stability and effectiveness of the filter screen.
[0009] Furthermore, the screen pressing frame is an annular structure, which is arranged along the outer periphery of the first shaping area, and its outer side surface is flush with the template in radial direction. This solution makes the overall structure of the fixed mold simple and compact.
[0010] Furthermore, the screen pressing frame and the template are fixed via a bolt structure.
[0011] Furthermore, the fixed mold also includes a drainage pipe fitting, which is arranged in the second drainage hole, and an outer convex edge is arranged around one side of the first molding area. The filter screen is provided with a second air-avoiding hole in coordination with the second drainage hole, and the outer convex edge abuts against the filter screen so that the inner peripheral edge of the second air-avoiding hole is pressed tightly against the side wall of the first molding area. The drainage pipe fitting of this scheme has a tightening effect on the filter screen, which is beneficial to improve the tightness of the connection between the filter screen and the first positioning area, and can prevent the part of the filter screen from being separated from the surface of the first molding area under repeated flushing of water flow. In actual applications, the drainage pipe fitting is installed from one end of the second drainage hole located in the first molding area.
[0012] Alternatively, the fixed mold further comprises a drainage pipe fitting, wherein the drainage pipe fitting is arranged in the second drainage hole, the filter screen extends to the inner circumference of the second drainage hole, and the drainage pipe fitting presses the filter screen tightly against the inner wall of the second drainage hole.
[0013] Furthermore, the filter screen is made of stainless steel. BRIEF DESCRIPTION OF THE DRAWINGS
