[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0024] like Figures 2 to 5 As shown, a high-efficiency wax injection mold is characterized in that it includes an upper mold 1 and a lower mold 2, the lower mold 2 includes a lower panel 11, the upper side of the lower panel 11 is provided with a groove 111, the lower side of the lower panel 11 is provided with a top plate 12 that moves up and down, the upper side of the top plate 12 is provided with an inclined ejector block 13 that moves up and down simultaneously with the top plate 12, the lower panel 11 is provided with an inclined guide groove, the inclined ejector block 13 passes through the inclined guide groove to the position of the groove 111, and the upper side of the inclined ejector block 13 is provided with a lower cavity for molding formed with the groove 111.
[0025] At this time, the inclined ejector block 13 and the groove 111 together form a cavity, which is used for product molding during the production process. At the same time, the inclined ejector block 13 is also used as a structure to eject the product molded in the cavity when the mold is opened, thereby realizing the ejection of the product.
[0026] At this time, the cavity is annular as a whole, and a plurality of steps are provided in the middle of the cavity. Therefore, in order to better eject the product in the cavity when the mold is opened, in this embodiment, the inclined ejector block 13 includes two relatively arranged first inclined ejector blocks 131 and two relatively arranged second inclined ejector blocks 132, and the two first inclined ejector blocks 131 and the two second inclined ejector blocks 132 are alternately and evenly distributed with the central axis of the cavity as the center.
[0027] At the same time, the upper end of the first inclined lift block 131 is located on the inner side of the cavity, and the upper end of the second inclined lift block 132 is located on the outer side of the cavity. During molding, the first inclined lift block 131 abuts against the inner side of the molded product, and the second inclined lift block abuts against the outer side of the molded product.
[0028] In this way, the two first inclined lift blocks 131 are located on the inner side of the cavity, and the two second inclined lift blocks 132 are located on the outer side of the cavity. After molding, the first inclined lift blocks 131 contact the inner side of the product, and the second inclined lift blocks 132 contact the outer side of the product, which can be used to support the product well. When opening the mold, the process of moving the product outward is more stable.
[0029] Furthermore, the upper ends of the two first inclined ejector blocks 131 are inclined toward the central axis of the cavity, and the upper ends of the two second inclined ejector blocks 132 are inclined away from the central axis of the cavity. Since the upper ends of the two first inclined lift blocks 131 are inclined toward the central axis of the cavity, the two first inclined lift blocks 131 also move upward during the mold opening process. Under the action of the inclined guide groove, the upper ends of the two first inclined lift blocks 131 move toward the middle position. At this time, the distance between the upper ends of the two first inclined lift blocks 131 becomes smaller and smaller. When the product does not move, the first inclined lift blocks 131 are separated from the product. Since the upper ends of the two second inclined lift blocks 132 are inclined away from the central axis of the cavity, the two second inclined lift blocks 132 move toward the outer position during the mold opening process. At this time, the distance between the upper ends of the two first inclined lift blocks 131 becomes larger and larger. When the product does not move, the second inclined lift blocks 132 are separated from the product. Therefore, during the mold opening process, the two first inclined lift blocks 131 move inward, and the two second inclined lift blocks 132 move outward, and are automatically separated from the product, thereby facilitating the subsequent removal of the product.
[0030] When opening or closing the mold, the first inclined lift block 131 and the second inclined lift block 132 need to move. At this time, it is necessary to ensure the stability of the first inclined lift block 131 and the second inclined lift block 132 during the movement. Therefore, in this embodiment, the upper side of the top plate 12 is provided with a first guide groove 141 and a second guide groove 142, and the first guide groove 141 and the second guide groove 142 are vertically arranged. The bottoms of the two first inclined lift blocks 131 are clamped in the first guide groove 141, and the bottoms of the two second inclined lift blocks 132 are clamped in the second guide groove 142. The first inclined lift block 131 slides in the first guide groove 141, and the second inclined lift block 132 slides in the second guide groove 142.
[0031] Specifically, the first guide groove 141 and the second guide groove 142 are T-shaped grooves, and the first inclined lift block 131 and the second inclined lift block 132 have a clamping portion at the bottom, and the first inclined lift block 131 and the second inclined lift block 132 are clamped in the first guide groove 141 and the second guide groove 142 through the clamping portion. At this time, since the distance between the two first inclined lift blocks 131 gradually decreases during the movement of the first inclined lift block 131, the bottom spacing of the first inclined lift blocks 131 will also gradually decrease. In the present embodiment, the first guide groove 141 is a whole, and the two first inclined lift blocks 131 are both clamped in the first guide groove 141. The second guide groove 142 is composed of two parts distributed in the second guide groove 142. The two second inclined lift blocks 132 are respectively located in the two parts of the second guide groove 142. In this way, during the mold opening process, under the action of the first guide groove 141 and the second guide groove 142, the first inclined lift block 131 and the second inclined lift block 132 can be horizontally moved along the direction of the first guide groove 141 and the second guide groove 142, and at the same time, they can be tilted along the direction of the inclined guide groove, thereby ensuring the stability of the first inclined lift block 131 and the second inclined lift block 132 during the movement.
[0032] Since the first inclined lift block 131 and the second inclined lift block 132 are used as part of the cavity and are arranged on the inner and outer side surfaces of the cavity, it is necessary to ensure that the upper end positions of the first inclined lift block 131 and the second inclined lift block 132 form a cavity with the upper panel during use, while not affecting the closing process of the upper mold 1 and the lower mold 2. Therefore, in this embodiment, the first inclined lift block 131 and the second inclined lift block 132 are flush with the upper side surface of the lower panel 11. If the product size does not need to be designed to be higher than the cavity, the upper panel side surface of the upper mold 1 can be set as a plane. If the product size is higher than the cavity, a partial cavity can be set on the upper panel so that the upper panel, the lower panel 11 and the inclined lift block 13 form a complete cavity at the same time.
[0033] Of course, in this embodiment, in order to facilitate production and improve production efficiency, in this embodiment, the lower panel 11 is provided with an insert 3, and the insert 3 is fixed to the upper side of the lower panel 11 by fasteners. Further, the insert 3 protrudes from the upper surface of the lower panel 11, and the lower side of the upper panel of the upper mold 1 is provided with a groove adapted to the insert 3. Further, the insert 3 is tapered as a whole. At this time, the insert 3 is a tapered shape with a small top and a large bottom. Specifically, the size of the side close to the upper mold 1 is smaller than the size of the side close to the lower mold 2. The four sides of the insert 3 are all inclined surfaces, which are fixed to the side position of the lower mold 2 by fasteners, and then the upper mold 1 is provided with a corresponding groove. In the process of mold closing, the insert 3 cooperates with the groove to complete the mold closing. At this time, the insert 3 has a certain guide left and right.
[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
