Problems solved by technology
[0005] At present, all dispensing syringes are made by mold injection molding process, such as figure 1 As shown, the existing dispensing syringe molding mold is formed vertically and does not have a parting line, which will cause some problems when the product is pulled out of the mold: 1) It is easy to damage the inner wall when pulled out, making the inner wall There is dust; 2) This molding process is likely to cause the eccentricity of the dispensing syringe, making the coaxiality worse

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0020] Such as Figure 2~4 Shown, a kind of manufacture method of dispensing syringe, comprises the steps:
[0021] A. Prepare a mold structure consisting of two mold cores 1 and a row insert 2, the two mold cores 1 and one row insert 2 are combined to form an injection molding space with a little glue syringe 3 structure;
[0022] B. Install the mold structure in step A on the injection molding machine, install the plastic to be injected, and then start the injection molding machine, so that a dispensing syringe 3 with a mold line 4 is formed in the injection molding space.
[0023] Preferably, the structure of the row insert 2 is the same as that of the dispensing syringe 3 , so that the above-mentioned mold structure can well produce an excellent dispensing syringe ...

The invention belongs to the technical field of glue storage containers, and in particular, relates to a manufacturing method of a glue dispensing syringe. The manufacturing method comprises the following steps: (A) a mold structure consisting of two mold cores and a traveling position insert is prepared; and the two mold cores and the traveling position insert are combined to form an injection molding space with a glue dispensing syringe structure; and (B) the mold structure in the step (A) is mounted on an injection molding machine; plastic needing to be injected is filled; and then, the injection molding machine is started to form the glue dispensing syringe with a mold closing line in the injection molding space. The glue dispensing syringe is formed by two mold cores through mold closing and injection molding; compared with no-mold-closing manufacturing in the prior art, the manufacturing method cannot generate eccentric problem on the inner wall of a syringe body of the glue dispensing syringe, and cannot generate the condition of pulling a product through mold opening, that is, the condition of inner wall damage caused by product pulling cannot be generated.
Description
technical field [0001] The invention belongs to the technical field of glue storage containers, in particular to a method for making a glue dispensing syringe. Background technique [0002] Dispensing syringes, also known as storage cylinders, syringes, etc., are containers for storing glue in pneumatic dispensing devices. [0003] It has various specifications ranging from 3-960ML (single-component and double-component). According to the characteristics of some glues, there are various colors to prevent the glue from reacting with light and sealing. [0004] Among them, the special amber dispensing syringe is suitable for the dispensing operation of the UV dispensing machine. The particularity of the amber dispensing syringe is reflected in its ability to shield UV light. In addition, there is also a black UV-resistant dispensing syringe, which has the function of UV protection. [0005] At present, all dispensing syringes are made by mold injection molding process, suc...
