Problems solved by technology

However, this often leads to the complexity of the mold structure or changes to the structural design of the product. Therefore, it is often encountered that only the latent gate structure can be used to complete the development of the mold. If this type of high-rigidity and high-strength plastic is used The latent gate structure is fragile or broken

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the description of the drawings and the preferred embodiments:

[0013] Please refer to figure 1 and figure 2 The preferred embodiment of the latent gate 100 of the present invention is applied to an injection mold 200 to dispense a product 300. The injection mold 200 includes a female mold plate 201, a female mold core 202, a male mold core 203, a male mold core 204, a punch 205, a heat insulation plate 206, an upper fixing plate 207, a stripper plate 208, The flow channel 209, a first ejector pin 210, a second ejector pin 211, an upper ejector plate 212, a lower ejector plate 213, two mold feet 214, and a lower fixed plate 215.

[0014] The heat insulation plate 206 is used to keep the injection mold 200 at a low temperature; the upper fixing plate 207 is used to fix the punch 205; the punch 205 is used as a feed port for receiving materials injected by an injection molding machine (not s...

Abstract

The invention relates to a submarine gate which is applicable for dispensing a product in an injection mold. The submarine gate comprises a body, an inputting material section and two guiding flanks. Top surface of the body is connected to a flow channel of the injection mold, and undersurface of the body is aligned to top surface of a thimble. The inputting material section is molded in one body with the body, and one side end of the body obliquely extends downward from above to form the inputting material section. The two guiding flanks are respectively arranged in two sides of the other side end of the body, wherein the other side end of the body is away from the inputting material section. Angles formed by the guiding flanks are parallel to central axis of the inputting material section, such that the two guiding flanks and the inputting material section form a double track guiding structure. The submarine gate provided by the present invention provides more broad design spaces and flexibility for product development.

Description

【Technical Field】 [0001] The invention relates to a latent gate, in particular to a latent gate used in an injection mold. 【Background technique】 [0002] The application of latent gates in injection molds is very common. The principle of mold ejection is to use the elasticity and toughness of the latent gate to make the plastics yield and deform under the force of the thimble to force them out of the cavity. Therefore, the prerequisite for the application of this latent gate is that the molded plastic must have sufficient elasticity and toughness. [0003] With the continuous introduction of new plastic materials, high-rigidity and high-strength plastics have become more and more widely used in modern industrial products due to their relatively low price, light weight and easy modeling. The characteristics of this type of plastic are excellent strength and rigidity, but its elasticity and toughness are greatly reduced compared with ordinary plastics. Therefore, this type of plast...
