Abstract

The utility model discloses a rubber mold cold runner structure, which comprises an upper mold plate, a cold runner plate, a heat insulating plate, an upper cavity plate, a lower cavity plate and a bolster. A sprue and a runner are arranged on the cold runner plate which is further provided with a cold runner for a cooling source to pass through, a cold runner penetrated with a heat source is arranged on the upper cavity plate and the bolster, a contact surface between the upper cavity plate and the lower cavity plate is a mold parting surface, and an upper cavity of the upper cavity plate is opposite to a lower cavity of the lower cavity plate so as to form a complete cavity. The cold runner for the cooling source to pass through is arranged approaching the sprue and the runner, and then temperature of the runner is reduced, rubber in the sprue can not be molded by heating, rubber remaining in the runner keeps a melting state and runner sprue condensed materials can not be generated, thereby saving cost greatly and increasing production efficiency.

Description

Rubber mold cold runner structure
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of rubber mold cold runner structure.
Background technology
At present, in the processing and forming manufacturing field of rubber product, because of characteristics such as its hot type mode have that the moulding expense is lower, molding cycle is short and forming process is simple, and widespread usage.Yet the heating unit of commonly using rubber mold all is located at the top of patrix, and not only with the rubber-moulding in the forming cavity, the while is also with the rubber-moulding in the running channel when heating.Running channel expects to be connected on the rubber finished product after the moulding with fixed attention, needs to go from finished product with manually running channel being coagulated material, and can't go utilization again, not only causes the waste of resource, more can waste very much because of throwing aside or burning and cause the pollution of environment, and economic benefit is low.
The utility model content
The purpose of this utility model is to provide a kind of rubber mold cold runner structure that reduces production costs.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of rubber mold cold runner structure, and it comprises cope match-plate pattern, cold flow guidance tape, thermal insulation board, upper impression plate, lower impressions plate, backing plate; Described cope match-plate pattern, cold flow guidance tape, thermal insulation board, upper impression plate are fixed together in regular turn by screw, are provided with to water road junction and runner on the cold flow guidance tape, also are opened in the cold runner that is used for by cooling source on the cold flow guidance tape; On upper impression plate and backing plate, offer the cold runner that places thermal source; The contact-making surface of described upper impression plate and lower impressions plate is a die joint, and the upper impression on the upper impression plate is relative with the lower impressions of lower impressions plate, constitutes a complete die cavity.
After adopting such scheme, because be provided with near road junction and the runner can be by the cold runner of cooling source watering for the utility model, thereby reduced the temperature of runner, avoided the interior rubber of runner to be subjected to thermoforming, the rubber of staying runner is in molten condition all the time, do not have the runner running channel to coagulate the generation of material, saved cost greatly, improved production efficiency.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of rubber mold cold runner structure, and it comprises cope match-plate pattern 1, cold flow guidance tape 2, thermal insulation board 3, upper impression plate 4, lower impressions plate 5, backing plate 6.
Described cope match-plate pattern 1, cold flow guidance tape 2, thermal insulation board 3, upper impression plate 4 are fixed together in regular turn by screw.On cold flow guidance tape 2, be provided with and water road junction 21 and runner 22, on cold flow guidance tape 2, also be opened in the cold runner 23 that is used for by cooling source; On upper impression plate 4 and backing plate 6, offer the cold runner 41,61 that places thermal source; The contact-making surface of described upper impression plate 4 and lower impressions plate 5 is die joint F, and the lower impressions 51 of upper impression on the upper impression plate 4 and 42 lower impressions plates 6 is relative, constitutes a complete die cavity.
The thermal source that the utility model is set in cold runner 41,61 can be electrical bar, hot fluid; In cold runner 23, inject water, cooling fluid, cooling wet goods.
Operation principle of the present utility model:
Inject cooling body near watering road junction 21 and runner 22 the cold runner 23, thereby reduced the temperature of runner 22, avoided runner 22 interior rubber to be subjected to thermoforming, the rubber of staying runner is in molten condition all the time; Simultaneously, on upper impression plate 4 and backing plate 6, be provided with in the cold runner 41,61 or the injection thermal source, make the rubber moulding as early as possible in upper impression plate 4 and lower impressions plate 5 die cavities.
Emphasis of the present utility model just is: adopt cold runner, make and water the road junction and runner is in lower temperature.
The above, it only is the utility model preferred embodiment, the position that the cold flow guidance tape is provided with can be different, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
