Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings.

The technical content and features of the present invention will be described in detail below with reference to the accompanying drawings, and those skilled in the art will understand that the present invention is mainly applied to plastic forming molds, particularly wax injection molds for dewaxing casting as an example, the following description of the embodiments is in principle and not limited to the application field, for example, the material or shape terms include and are not limited to the material or shape designated by the description, the position terms include and are not limited to the arrangement, the proximity, the connection, or the adjacency, the quantity terms of each element "a" and "at least one" include one or more than one element quantity, and the directional terms mentioned in the description are only exemplary terms based on the normal use direction and are not intended to be the scope of the claims.

As shown in fig. 1, the present invention provides a demolding device for a forming mold 50, wherein the forming mold 50 mainly comprises two mold bases 52 and a hollow film cavity 54 disposed between the two mold bases 52. The demolding device comprises a base 10, the base 10 includes an air storage chamber 12, an air inlet channel 14 communicating with the air storage chamber 12, and a plurality of air outlet channels 16 communicating with the air storage chamber 12, the base 10 is disposed on one of the mold bases 52, the base 10 in the preferred embodiment is stacked on the bottom of one of the mold bases 52 as an example, the plurality of air outlet channels 16 are sequentially arranged and communicated with the hollow film cavity 54, and the air outlet channels 16 in the preferred embodiment are linearly arranged as an example.

A pushing element 20 is disposed inside each air outlet channel 16 of the base 10, each pushing element 20 is disposed on each air outlet channel 16 in a reciprocating manner, each pushing element 20 has a head end 22 and a rod body 24, the head end 22 is displaced along the inner wall surface of the air outlet channel 16, the rod body 24 of each pushing element 20 is selectively provided with an elastic element for reciprocating the pushing element 20 on the air outlet channel 16, the head end 22 of the pushing element 20 can move back and forth between the abutting position of the flush hollow membrane cavity 54 and the air outlet channel 16 and the position protruding into the hollow membrane cavity 54, and the elastic force of the elastic element is used for abutting the flush hollow membrane cavity 54 of the pushing element 20 and the air outlet channel 16. When the head 22 is flush with the adjacent portion of the hollow membrane cavity 54 and the air outlet channel 16, the air outlet channel 16 is in a closed state, and when the head 22 protrudes toward the hollow membrane cavity 54, the air outlet channel 16 is in an open state.

Through the above-mentioned components, when the high-pressure gas is introduced into the gas accumulation chamber 12 through the gas inlet channel 14, the high-pressure gas flows to the gas outlet channels 16, and the head ends 22 of the pushing members 20 are driven to protrude into the hollow film cavity 54 according to the pressure of the gas, and when the gas stops being introduced into the gas inlet channel 14, the pushing members 20 are driven to move to the position flush with the adjacent position between the hollow film cavity 54 and the gas outlet channel 16. If the utility model is used in the wax injection process of dewaxing casting, the wax mold 30 is formed and solidified in the hollow film cavity 54, and the two mold bases 52 are mutually opened and simultaneously injected with gas into the gas inlet channel 14, so that each pushing part 20 driven by the gas protrudes into the hollow film cavity 54, and the wax mold 30 can be pushed out of the hollow film cavity 54 to complete the wax injection process. Because the formed wax mold 30 and the mold seat 52 do not need to be separated manually, the appearance of the wax mold 30 is not easy to be damaged, the quality of the finished product is maintained, the ejection force of the pushing piece 20 can be changed by adjusting the pressure of gas, and even the wax mold with lower strength can be moved away from the mold seat by the demolding device, thereby achieving the purposes of improving the manufacturing quality and efficiency and the like.
