Problems solved by technology

Fast food boxes are generally manufactured through molds. The existing lunch box molds are generally divided into an upper mold and a lower mold. An injection cavity is formed between the upper and lower molds. The material liquid directly enters the mold cavity for injection molding. The flow of the feed liquid in the flow channel is not smooth, and the feed liquid cannot fill the mold cavity quickly and evenly, which leads to the thickness of the prepared lunch boxes.
[0003] In view of the above problems, the existing patent notification number is CN206913598U patent has announced a fast food box processing mold, the device is provided with a flow diversion cone with a diversion groove, which can evenly drain the material liquid entering through the flow channel mouth into the flow distribution channel, After being transported through the runner and flowing into the mold cavity through the gate, it can ensure that the material liquid can evenly fill the entire cavity, and ensure that the product surface is smooth and uniform in thickness. However, this guiding method is still difficult to ensure that the material liquid fills the entire mold. Cavity

Embodiment 1

[0027] see Figure 1-2 , in an embodiment of the present invention, a fast food box processing mold includes a base 1 and a top plate 10 arranged above the base 1, and support columns 8 are arranged symmetrically on both sides of the lower end of the top plate 10, and between the top plate 10 and the base 1 An upper module 22 and a lower module 23 are provided;

[0028] The upper end of the upper module 22 is connected and fixed with the lower module 23 through the injection molding assembly, and the water outlet end of the injection molding assembly is connected with the injection hole 16 on the upper module 22, and the injection hole 16 communicates with the injection cavity between the upper and lower modules. , the outer side of the liquid injection hole 16 is provided with a shunt pipe 17 for shunting the material into the injection molding cavity;

[0029] The upper module 22 and the lower module 23 are connected by a positioning assembly, and the bottom of the lower mo...

Embodiment 2

[0039] see image 3 , the difference from Embodiment 1 is that: the lower module 23 is provided with a cooling assembly, the cooling assembly includes a cold water chamber arranged inside the lower module 23 and a cold water chamber 103 arranged inside the base 1, and the rotating shaft 25 The lower end extends into the water-cooling chamber 103, and the inside of the rotating shaft 25 is provided with a water guide channel 105 that is convenient for cold water to enter the cold water chamber for cooling treatment. There is a drain, and the base 1 is provided with a backwater hole 102 for water to enter the inside of the cold water chamber 103, and the upper end of the base 1 outside the backwater hole 102 is provided with an enclosure 101 to prevent water from flowing out;

[0040] Since the upper and lower modules are in a rotating state during injection molding, when the upper and lower modules rotate forward, the blades 104 will not generate upward thrust on the water, and...

Abstract

The invention discloses a fast food box processing mold. The fast food box processing mold comprises a base and a top plate arranged above the base, supporting columns are symmetrically arranged on the two sides of the lower end of the top plate, and an upper mold block and a lower mold block are arranged between the top plate and the base; the upper end of the upper mold block is fixedly connected with the lower mold block through an injection molding assembly, the water outlet end of the injection molding assembly is connected with a liquid injection hole in the upper mold block, the liquidinjection hole communicates with an injection molding cavity between the upper mold block and the lower mold block, and a flow dividing pipe used for dividing materials into the injection molding cavity is arranged on the outer side of the liquid injection hole; and the upper mold block and the lower mold block are connected through a positioning assembly. According to the fast food box processingmold, the upper mold block and the lower mold block rotate, centrifugal force is used for forcing materials to fill the injection molding cavity, meanwhile, the injection molding effect is guaranteedthrough atmospheric pressure auxiliary pushing, in addition, the mold rotates to be matched with a cooling assembly, so that the machining efficiency is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a fast food box processing mold. Background technique [0002] With the accelerated pace of life, the food delivery industry is developing rapidly, and the use of disposable lunch boxes is growing rapidly. Fast food boxes are generally manufactured through molds. The existing lunch box molds are generally divided into an upper mold and a lower mold. An injection cavity is formed between the upper and lower molds. The material liquid directly enters the mold cavity for injection molding. The flow of the feed liquid in the flow channel is not smooth, and the feed liquid cannot fill the mold cavity quickly and evenly, which leads to the thickness of the box wall of the prepared lunch box. [0003] In view of the above problems, the existing patent notification number is CN206913598U patent has announced a fast food box processing mold, the device is provided wit...
