、，習知成型生産中，經過模具成型後之産品一般都帶有 九道料頭，如圖1所示成型後之産品5〇，該産品5〇帶有一澆 道料頭51，該澆道料頭51為開模時殘留在澆道内之熔融之 塑膠連著模具型腔内之成型品而形成，該澆道料頭51經後 加工製程去除，工作人員將該帶有洗道料頭51之産品5〇置 _於治具上，經過操作該治具以去除所述澆道料頭51，澆道 料頭51去除後，一般會在該去除邊沿形成毛邊，工作人員 ，而修整以去除毛邊，去除毛邊後，産品再經過檢視後包 裝。如此產品後加工製程工序繁多，既需較多人力，又需 有專門為去除澆道料頭而設計之治具，且還常會出現於去 料頭時治具損壞産品之現象。 針對後加工製程工序繁多之問題，設計人員採取一種 在腔側邊设置進澆口，在該進澆口處設置扁鎖來切斷洗 道料頭之方法。如圖2所示，模具i包括一公模2、一母 7 200831262 模4及一扁銷6，該公模2與母模4形成一型腔204，——澆 道206及與洗道206對應之洗口 208設置於型腔204之一 侧，熔融塑膠流過澆道206由澆口 208注入型腔204，所 述扁銷6貫穿公模2且抵於洗口 208處，當熔融塑膠充滿 型腔204後，扁銷6向上移動以切斷澆道206形成之澆道 料頭。該種於侧邊澆口設置扁銷之方式能將澆道内形成至 澆口處之澆道料頭切斷，能於成型時將料頭去除使成型後 之産品不帶有洗道料頭，減少了後加工製程中之工序，也 ❿ 節省了大量之人力及財力，越來越多之模具採用這種技 術。然該種技術僅適用於成型對應於澆口處産品無孔洞之 産品，當成型對應模具之澆口處開有孔洞之産品時，殘留 於該産品上形成孔洞中之塑膠形成之産品廢料只能經過後 加工製程去除。如圖3所示，該成型後之産品60之澆口料 頭經模内洗道料頭切除機構已去除，然其産品廢料62仍附 著於産品60上，該産品廢料62需經後加工製程去除。習 0知技術中，這種與澆道料頭連體之産品廢料之去除還只能 通過後加工製程達成，不能通過模内剪切以去除産品廢料。 【發明内容】 鑒於上述内容，有必要提供一種用於去除澆道料頭及 與所述洗道料頭連體之産品廢料之模内切料機構。 另外，有必要提供一種應用所述模内切料機構之模具。 一種模內切料機構，其應用於一種模具，該模具包括

Field of the Invention The present invention relates to an in-mold cutting mechanism, and more particularly to an in-mold cutting mechanism for a plastic mold and a mold using the in-mold cutting mechanism. [Prior Art] At present, most of decorative products or consumer electronic products rely on mold molding. In particular, with the development of the modern electronics industry, all kinds of products need to be molded into the shell, and the role of the mold is also more Significantly important, at the same time, the optimization of the mold design and the improvement of related processes have become the more south goal of the mold industry. In the conventional molding production, the product after molding by the mold generally has nine material heads, and the product after molding as shown in FIG. 1 has 5 turns, and the product 5 has a sprue head 51, the runner The material head 51 is formed by the molten plastic remaining in the runner when the mold is opened, and is connected to the molded product in the mold cavity. The runner head 51 is removed by a post-processing process, and the worker will carry the shampoo head 51. The product 5 is disposed on the jig, and after the jig is operated to remove the sprue head 51, after the sprue head 51 is removed, a burr is generally formed at the removing edge, and the worker is trimmed to remove Raw edges, after removing the burrs, the products are packaged after inspection. Such a product has a large number of post-processing processes, requires a lot of manpower, and requires a fixture designed to remove the sprue head, and often occurs when the fixture is damaged when the material is removed. In view of the numerous problems in the post-processing process, the designer adopts a method of setting a gate at the side of the cavity and a flat lock at the gate to cut the head of the washway. As shown in FIG. 2, the mold i includes a male mold 2, a female 7 200831262 mold 4 and a flat pin 6. The male mold 2 and the female mold 4 form a cavity 204, a runner 206 and a wash tunnel 206. The corresponding washing port 208 is disposed on one side of the cavity 204, and the molten plastic flows through the runner 206 and is injected into the cavity 204 by the gate 208. The flat pin 6 penetrates the male die 2 and abuts the washing port 208 when the molten plastic is After filling the cavity 204, the flat pin 6 moves upward to cut the sprue head formed by the runner 206. The method of setting the flat pin on the side gate can cut the sprue material head formed in the sprue to the gate, and can remove the material head during molding, so that the molded product does not have a washing material head. It reduces the number of processes in the post-processing process, and also saves a lot of manpower and financial resources. More and more molds use this technology. However, this technology is only suitable for molding products that do not have holes in the product at the gate. When forming a product with holes in the gate of the corresponding mold, the product waste formed by the plastic remaining in the hole in the product can only be After the post-processing process is removed. As shown in FIG. 3, the gate material of the molded product 60 has been removed by the in-mold scrubbing head cutting mechanism, but the product waste 62 is still attached to the product 60, and the product waste 62 is subjected to a post-processing process. Remove. In the prior art, the removal of the product waste that is connected to the sprue head can only be achieved through the post-processing process, and the in-mold shear cannot be used to remove the product waste.

The second lower pre-top plate 464 abuts the pull ejector pin 49 to prevent the pull-up thimble 49 from coming off. The second spring 466 and the second second screw 468 are the same as the first spring 446 and the second first screw 448 of the first supporting mechanism 44, and will not be described here. Referring to FIG. 4 and FIG. 5, the inscribed ejector pin 48 is a substantially cylindrical structure having a concave end portion 482 formed at one end thereof, and the concave end portion 482 has a peripheral edge 4822 and a bottom portion 4824. The peripheral edge 4822 is located at the outer periphery of the concave end portion 482 and has a small width for engaging the female mold core 16 to shear product waste. The other end of the inscribed thimble 48 extends radially to form a boss 484 for mating with the stepped hole 4422. A pull hole 486 is defined in the middle of the inscribed thimble 48. The pull hole 486 is a circular hole. The pull hole 486 extends through the entire inner ejector pin 48. The pull hole 486 is used to assemble the pull ejector pin. 49. The pull ejector 49 also has a substantially cylindrical structure, and one end thereof forms a P-shaped end portion 492 for detaching the sprue material from the female mold 10 when the mold is opened. The other end of the thimble 49 also extends along the radial direction thereof to form a second boss 494 for engaging the second stepped hole 4622. During molding, the master mold 10 is clamped to the male mold 20, and the male mold core 29 and the female mold core 16 form a cavity 210 through which the molten plastic is injected through the nozzle 182 of the nozzle bushing 18 and flows through the flow passage 186. The gate 184 is injected into the cavity 210. After the molten plastic is filled into the cavity 210, when the plastic is solidified but not fully cured, the cutting mechanism 40 is actuated to drive the first support of the first support structure 44 by an external force. The top plate 444 and the second lower pre-top plate 464 of the second support structure 46 cause the inner cutting thimble 48 and the pull ejector pin 49 to approach the female die core 16 at the same speed, when the inner edge of the inner cutting pin 48 is 4482 and the female die core 16 After the contact, the product waste of the product in the cavity 210 is cut, and then the male mold 20 is moved downward to be separated from the master mold 10, at which time the bottom of the product waste is limited by the wedge-shaped end portion 492, The mold 20 is moved downward, and since the product waste is integrally connected with the washing head, the sprue head connected to the flow path 14 200831262 186 of the female mold 10 is broken, so that the sprue material is The master mold separates the 'external force, the early independence, the driver, the second standard structure, the fourth lower pre-top board 464 The pull ejector 49 is moved upward relative to the inner ejector pin 48 such that the tapered end portion 492 of the pull ejector pin 49 projects from the pull hole 牝6 of the inner nip pin 48, and the waste can be detached from the pull ejector pin 49. Thereby, the shampoo head and product waste are removed. Thereafter, the ejector plate 34 is pushed up by an external force to cause a plurality of thimbles to push the molded product, thereby ejecting the molded product on the male mold of the lower mold 2, thereby completing the production of the molded product. Referring to FIG. 6 , the invention adopts the in-mold cutting mechanism to form a product after the in-mold=intentional comparison with FIG. 1 and FIG. 3, the washing head of the product 70 and the production: the waste-to-plate cutting mechanism is completely cut, A hole 73 is formed. This greatly reduces the j = the order of the manufacturing process. 'There is no need to trim the cutting head and trimming, and it also saves the cost of producing or purchasing the fixture. In summary, the in-mold material head shearing structure of the present invention can have a conditional material head and product waste, which greatly increases
