Abstract
The utility model discloses a refrigerator -freezer mould close foaming door body and function sprue handhole door, characterized by sets up half the round circular structure around the sprue handhole door, and sprue semicircle type circular structure forms seal structure with the door shell cooperation. The utility model discloses can effectively guarantee the leakproofness of door shell and sprue handhole door to reduce production operation improves product quality.
Description
Technical field
This utility model relates to a kind of refrigerator-freezer foaming inclosed molds door body leak stopping sprue port lid.
Background technology
At present, it is polypropylene (PP) that household electrical appliances manufacturing commonly uses material, with the sprue port lid that door shell fit structure is jack catchs type, sprue is sealed, production technology is mainly as follows: use frock to block sprue after material feeding refrigerator-freezer foaming inclosed molds door body, after solidifying Deng door foaming, sprue port lid is installed again, to ensure that in foaming process, expanding foam solution does not overflow from sprue.But because door shell sprue place intensity is not enough, during manually installed frock, there is part sprue place modification, after causing foaming, PP material sprue port lid jackcatch fracture maybe cannot be installed, and has had a strong impact on product quality.
Summary of the invention
This utility model is for overcoming existing sprue design structure and leak-stopping technique defect, it is provided that a kind of refrigerator-freezer foaming inclosed molds door body sprue port lid, to being effectively ensured the sealing of sprue port lid and door shell, thus simplifying production operation operation, improves product quality.
This utility model solves technical problem and adopts the following technical scheme that
The feature of this utility model a kind of refrigerator-freezer foaming inclosed molds door body sprue port lid is: the surrounding at sprue port lid is provided with semi-circular arc structure, and described semi-circular arc structure is elastomer；It is close to the upper surface of refrigerator-freezer door shell with the bottom surface of described semi-circular arc structure, and with described elastic physical ability, its inner chamber gas is formed outside discharge structure, thus the sealing structure formed between described sprue port lid and described refrigerator-freezer door shell.
The feature of this utility model refrigerator-freezer foaming inclosed molds door body sprue port lid lies also in:
The radius of described semi-circular arc structure is more than 4MM.
Described elastomer is quality of rubber materials.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, this utility model is by arranging semi-circular arc structure in the surrounding of sprue port lid, can be fully contacted with door shell face, again through manual compression semi-circular sprue structure when installing, make in semi-circular arc structure gas through discharging, negative pressure is formed in the contact position of sprue port lid with door shell face, and then make sprue and door shell energy tight seal, thus simplifying production operation operation, improve product quality.
2, this utility model structure sprue port lid can be installed before foaming inclosed molds door foaming, eliminate sprue leak stopping frock in door foaming process, decrease production operation operation, avoid the problem because using frock to cause sprue modification, improve produced on-site efficiency, compare that former sealing means is relatively reliable and concordance is high.
3, this utility model structure sprue port lid is quality of rubber materials, and not easily bending fracture, easy for installation.

Fig. 3 is A-A place sectional view in Fig. 2；
Fig. 4 is that this utility model uses view；
Number in the figure: 1 sprue port lid；The 2 semi-circular arc structures of sprue port lid；3 refrigerator-freezer door shells.
Detailed description of the invention
In the present embodiment, as depicted in figs. 1 and 2, a kind of refrigerator-freezer foaming inclosed molds door body sprue port lid, is that the surrounding of sprue port lid 1 is provided with semi-circular arc structure 2, and semi-circular arc structure 2 is elastomer；As shown in Figure 4, it is close to the upper surface of refrigerator-freezer door shell 3 with the bottom surface of semi-circular arc structure 2, and with elastic physical ability, its inner chamber gas is formed outside discharge structure so that sprue port lid 1 can cooperatively form sealing structure with contacting between refrigerator-freezer door shell 3.
In being embodied as, as it is shown on figure 3, the radius of semi-circular arc structure 2 is more than 4MM.Bottom semi-circular arc structure 1 smooth, and width is more than 2MM.Elastomer is quality of rubber materials.After sprue port lid 1 assembles with refrigerator-freezer door shell 3, semi-circular arc structure 2 contacts with door shell face, discharges semi-circular arc structure 2 gas through extruding, forms negative pressure with door shell, it is achieved tight seal, thus preventing expanding foam solution to overflow from cooperation.
This utility model refrigerator-freezer foaming inclosed molds door body sprue port lid can be widely applied to refrigerator-freezer foaming inclosed molds disciple's sprue leak stopping, decreases production operation operation, improves production efficiency.
Claims (3)
1. a refrigerator-freezer foaming inclosed molds door body sprue port lid, is characterized in that: the surrounding at sprue port lid (1) is provided with semi-circular arc structure (2), and described semi-circular arc structure (2) is elastomer；The upper surface of refrigerator-freezer door shell (3) it is close to the bottom surface of described semi-circular arc structure (2), and its inner chamber gas is formed outside discharge structure with described elastic physical ability, thus the sealing structure formed between described sprue port lid (1) and described refrigerator-freezer door shell (3).
