Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inclined top demoulding moulds, in particular to a segmented inclined top demoulding mould. Background Art
[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. They mainly realize the processing of the shape of the object by changing the physical state of the molded material. There are many types of molds, which can be divided into hardware molds, plastic molds, and special molds according to the different molding materials.
[0003] There is a complex product with multiple teeth in the product structure. After the injection molding is completed, it is found that it is difficult to demould. When the ejector mechanism is used for demoulding, the injection molded parts are damaged due to the high strength, which increases the working cost and reduces the working efficiency.
[0004] To this end, we provide a segmented inclined top demoulding mold. The product has round teeth and a compact structure. The full circle of external teeth allows the opponent to be screwed in smoothly. Because the correct teeth cannot be achieved, the original full circle of teeth is changed to a segmented type. Only with a unique processing method can the product function smoothly. Utility Model Content
[0005] The purpose of the utility model is to provide a mold with segmented inclined top demoulding to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a segmented inclined top demolding mold, comprising a mold core, two gate sleeves are provided on the top of the mold core, two core grooves are provided on the mold core, and a connecting channel is provided between the two core grooves to facilitate material flow and pressure balance; a plastic product is built into the core groove, the plastic product is circular, and there are three trimming heads on the plastic product.
[0007] Preferably, the outer wall of the tooth trimming head is provided with three sections of tooth patterns.
[0008] Preferably, a corresponding inclined top groove is provided in the core groove, and an inclined top is adapted in the inclined top groove. The inclined top grooves are grouped into three, and there are three groups of inclined top grooves in one core groove.
[0009] The utility model provides a mold with segmented inclined top demoulding. It has the following beneficial effects:
[0010] (1) The utility model adopts three groups of inclined top grooves, each of which is equipped with an inclined top. Under separate slow wire cutting, the teeth are punched separately. The product teeth are ejected in the form of an inclined top limit. The teeth are formed by separate wire cutting → processed by a grinder → the serial numbers of each group are identified → discharge in sequence according to the electrode angle. One electrode for each group of teeth satisfies the requirement of complete tooth shape and smooth tooth rotation. Among them, the electrode processing method is: the lathe overall tooth shape is processed according to the standard → the wire cutting is then processed to calibrate the table base → the teeth are divided into 3 sections by wire cutting according to the base processing. Finally, the inclined top demoulding mold is realized in efficient production while ensuring the exquisiteness of product details and the stability of the process.
[0011] (2) The utility model has a round tooth structure and a compact structure, and the whole circle of external teeth enables the counterpart to be screwed in smoothly. Since the correct tooth cannot be achieved, the original whole circle of teeth is changed into a segmented type, which has a unique processing method to enable the product to function smoothly. The product adopts an inverted mold opening structure, the rear mold is inclined to remove the teeth, and the large angle is ejected for rapid demoulding. The product has a latent glue injection outside, the mold opening is smooth, and the demoulding production process is efficient. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0019] The preferred embodiment of the segmented inclined top demoulding mold provided by the present invention is as follows: Figure 1-4 As shown: A segmented bevel demoulding mold includes a mold core 11, and two gate sleeves 12 are provided on the top of the mold core 11. By providing the mold core 11 and cleverly arranging the layout of the bevel groove 15 in its internal structure, the functions of efficient demoulding and fine tooth trimming are achieved. Two core grooves are provided on the mold core 11, and a connecting channel is provided between the two core grooves to facilitate material flow and pressure balance; a plastic product 13 is built into the core groove, and the plastic product 13 is circular, and there are three tooth trimming heads on the plastic product 13; the outer wall of the tooth trimming head is provided with three sections of tooth pattern 14; a matching bevel groove 15 is provided in the core groove, and a bevel is adapted in the bevel groove 15, and the bevel groove 15 is grouped into three, and there are three groups of bevel grooves 15 in one core groove. The design of the mold of the utility model enables the bevel action of the plastic product to be more accurately controlled during the demoulding process, thereby improving the accuracy and efficiency of the tooth trimming head. In addition, the combination of inclined top grooves helps to simplify the mold structure and reduce manufacturing costs, while ensuring the stability and consistency of the product. The entire process is clean and neat, with optimized structure, short cycle and greatly improved production efficiency.
[0020] Three groups of inclined top grooves 15 are used, and inclined tops are adapted in the inclined top grooves 15. Under separate slow wire cutting, the teeth are punched separately. The product teeth are ejected in the inclined top limit mode, and are formed separately by wire cutting → processed by a grinder → after the serial numbers of each group are identified → discharge in sequence according to the electrode angle. One electrode for each group of teeth satisfies the complete tooth shape and smooth tooth rotation. Among them, the electrode processing method is: the overall tooth shape of the lathe is processed according to the standard → then the wire cutting is processed to calibrate the table base → then the teeth are divided into 3 sections by wire cutting according to the base processing, which finally realizes the efficient production of the inclined top demoulding mold while ensuring the exquisiteness of the product details and the stability of the process.
