Description

Technical Field

[0001] This application relates to the field of preform molds, and more particularly, to a preform mold with precise temperature control. Background Art

[0002] A preform is a product used for blow molding to obtain a bottle. That is to say, a preform is an upstream product of a bottle, and the quality of the preform will affect the quality of the bottle obtained by subsequent blow molding. Preforms are usually prepared by injection molding using an injection mold. Therefore, a preform molding mold is the main equipment for preparing preforms. A preform molding mold is usually provided with a cavity in the shape of a preform, and then a preform finished product is obtained through hot injection molding. Preform molding molds are widely used in the processing and production of preforms.

[0003] The structure of the product can refer to a preform molding mold disclosed in Chinese Patent Document CN217944138U, which includes: an upper template, a lower template, a plurality of first models, a plurality of second models, and a plurality of mold cores. The upper template is provided with a plurality of mounting holes. Each first model is provided with a first cavity, each second model is provided with a second cavity, and each second cavity communicates with a first cavity. A cavity is formed between each mold core and the inner side walls of a first cavity and a second cavity, and the cavity is used for injection molding to obtain a preform.

[0004] In the above structure, a liquid cooling method is used for cooling and heat dissipation. However, in actual use, due to the lack of a temperature control device, it is not conducive for users to precisely control the cooling temperature value of the molded part in the mold cavity. If the mold cools rapidly, it is easy to cause the molded mold to crack and open, affecting the yield. When the mold cools slowly, the injection molding efficiency will be low. Summary of the Utility Model

This section of the application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

At this time, the coolant in the cold water tank will enter the flow distribution rack under the guidance of the circulation pump, the first connecting pipe, and the second connecting pipe, and is divided by the flow distribution rack into two. Since the two cooling pipes are respectively located above the inside of the lower mold, the positions of the cooling pipes are close to the bottoms of multiple mold cavities on the lower mold, and the surrounding material of the mold cavity is a heat-conducting material, so as to achieve efficient cooling of the molded die in the mold cavity. And the ends of the cooling pipes are connected to the cold water tank, so as to achieve the recycling of the coolant.

The number of the mold cavities 24 is equivalent to that of the alignment injection ports 25, and the mold cavities 24 and the alignment injection ports 25 are distributed in an alignment manner.

[0027] In the installed state of the preform mold, a plurality of positioning guide rods 21 provided inside the lower mold 1 will be inserted into corresponding guiding holes 23 provided inside the upper mold 22 in alignment. At the same time, the driving end of a driver (not shown in the figure) should be connected to the outside of the upper mold 22.

[0028] Among them, the temperature control mechanism 4 includes a cooling component 41, and the cooling component 41 is installed inside and outside the lower mold 1 and the base mounting frame 3.
