[0051] see Figure 2a-10 , the first embodiment of the present invention provides a hot runner mold system, which is suitable for the injection molding preparation of deep-hole plates, specifically an open hot runner mold system, that is, it is matched with the injection molding machine and injected The start and stop of injection molding production is realized under the pressure provided by the machine to the injection molding compound.

[0052] Specifically, see Figure 2a and Figure 2b , the hot runner mold system includes a template 200 and a hot runner device 100 .

[0053]The template 200 has a cavity of a deep-hole plate and a plurality of point gates corresponding to the holes of the deep-hole plate. That is, the mold cavity of the template 200 is suitable for deep-hole plate products, and when the injection molding compound enters the cavity, the injection compound can be molded into a deep-hole plate in the cavity. As mentioned in the background technology, the ...

[0100] The second embodiment of the present invention provides a hot runner mold system, which differs from the first embodiment only in that: Figure 11 , The fit between the tip 7 and the lower splitter plate 6. This difference will be introduced below, and the rest of the content that is the same as the first embodiment will not be repeated.

[0101] Different from the main body 8 provided between the nozzle 7 and the lower distributor plate 6 in the first embodiment, in this embodiment, a plurality of glue outlets are formed on the lower surface of the lower distributor plate 6, and the nozzle 7 is set as a nozzle core And through the flange 14, it is attached to the lower surface of the lower distributor plate 6, so that the nozzle 7 can be directly connected with the flow channel of the flow channel mechanism.

[0102] For the 96-orifice plate, the number of glue outlets is 96. Correspondingly, the lower surface of the lower manifold 6 has 96 nozzles 7 fitted through th...

[0104] The third embodiment of the present invention provides a hot runner mold system, which differs from the first embodiment only in that: Figure 12 , The fit between the tip 7 and the lower splitter plate 6. This difference will be introduced below, and the rest of the content that is the same as the first embodiment will not be repeated.

[0105] Different from the nozzle 7 of the first embodiment and the main body 8 provided between the lower distributor plate 6, in this embodiment, the lower surface of the lower distributor plate 6 is formed with a plurality of glue outlets, and each of the glue outlets is surrounded by a Groove; the nozzle 7 is set as a nozzle core, and the upper end of the nozzle core is embedded into the groove through the pressure cap 15, thus the flow channel between the nozzle 7 and the flow channel mechanism can be directly realized butt.

[0106] For the 96-hole plate, the number of glue outlets is 96, and correspondingly, the lower surface o...

Abstract

The invention discloses a hot runner mold system for a deep hole plate. The hot runner mold system for the deep hole plate comprises a template and a hot runner device, wherein the template is provided with a cavity of the deep hole plate and a plurality of pin-point gates corresponding to a plurality of holes of the deep hole plate in a one-to-one mode, the hot runner device comprises a main sprue bushing, a plurality of sharp nozzles matched with the pin-point gates in a one-to-one mode, and a runner mechanism arranged between the main sprue bushing and the sharp nozzles, a sizing material runner is formed in the runner mechanism, and the main sprue bushing communicates to each sharp nozzle through the runner. Compared with the prior art, the hot runner mold system for the deep hole plate has the following beneficial effects that on one hand, a hot runner injection molding process can be adopted to realize processing and manufacturing of the deep hole plate; and on the other hand, byarranging the pin-point gates and the sharp nozzles which are in one-to-one correspondence with the holes of the deep hole plate, the synchronous glue injection of the holes of the deep hole plate isrealized, the product quality of the deep hole plate is ensured, and the defect of the bottoms of the holes caused by the backward pouring of glue materials of part of the holes due to the asynchronous glue feeding of the holes is avoided.

Description

technical field [0001] The invention belongs to the technical field of hot runners and relates to a hot runner mold system for deep-hole plates. Background technique [0002] Deep-well plates, also known as deep-well storage plates, are experimental consumables that have been widely used in the field of biological and medical testing. Deep-well plates have multiple holes (or multiple cavities), and each hole can be used to store samples. , has various advantages such as tidy storage, space saving, large storage capacity, and low temperature resistance. According to the number of wells, a 96-well plate is currently a common deep-well plate, that is, there are 96 wells in a deep-well plate that can be used independently to store samples. [0003] At present, the processing and production of deep-hole plates basically adopts cold runner injection molding, and cold runner injection molding will generate a lot of waste, which is not conducive to economic and environmental protec...
