Description

Technical Field

[0001] The utility model relates to the technical field of household appliance molds, in particular to a demoulding device for household appliance molds. Background Technique

[0002] Household appliance molds are used to manufacture household appliance products, including the shells, components, etc. of household appliances such as televisions, air conditioners, refrigerators, washing machines, and microwave ovens. According to different process characteristics and uses, household appliance molds can be divided into various types, mainly including injection molds, stamping molds, casting molds, etc.

[0003] Reference can be made to the existing literature, a demoulding device for household appliance molds (CN218134582U). In the reference, through the left and right ejector rods provided, the stamping plate can be stably lifted, so that the force is evenly distributed and deformation will not occur. And after the stamping plate is ejected, by starting the motor, the stamping plate can be directly pushed onto the sliding plate by the pushing plate and directly fall into the receiving box below, so that there is no need for the operator to reach under the upper die to take the material, which brings sufficient protection to the personal safety of the operator. And this way of not manually taking the material also reduces the physical exertion of people to a certain extent.

[0004] At present, when demoulding household appliance molds, the workpiece is often pushed out by a telescopic component to complete demoulding. For example, in the above-mentioned literature, the workpiece is pushed out by the longitudinally movable ejector rod. This kind of design generally processes and demoulds single products, and the processing efficiency of a large number of household appliance parts on the production line is relatively low. Therefore, a demoulding device with a multi-cavity structure in one mold and capable of processing and demoulding multiple products simultaneously is designed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a demoulding device for household appliance molds is proposed. Through the docking component, the four stamping plates can be quickly connected to the central seat, and at the same time, the lower mold is split into an outer frame and a base part, and stamping operations can be carried out at multiple stations simultaneously. And the operation of the second electric cylinder drives the four lower mold bases through the demoulding push plate to push out the products in the lower mold outer frame to complete demoulding.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A second electric cylinder 8 is fixedly installed at the central position of the bottom plate 3. The telescopic end of the second electric cylinder 8 is connected to a demolding push plate 4. The demolding push plate 4 is provided with four lower mold bases 23 at the upper end. The bottom of the outer frame 6 of the lower mold is hollowed out and provided with four. The lower mold bases 23 are all inserted into the inner groove of the outer frame 6 of the lower mold. The central seat 11 is square and is connected with a stamping plate 13 on four sides through a docking component. The bottom of the stamping plate 13 is integrally provided with an upper mold 14. An installation groove is provided at the central position of the bottom plate 3 for fixing the second electric cylinder 8. The telescopic end of the second electric cylinder 8 is directly fixed to the demolding push plate 4. The demolding push plate 4 can move up and down in the inner groove of the outer frame 6 of the lower mold through the four lower mold bases 23 above, and then the workpiece in the inner groove of the outer frame 6 of the lower mold can be pushed out after stamping to complete demolding. The central seat 11 is connected to the stamping plates 13 on four sides. After the central seat 11 moves downward, it can drive the four stamping plates 13 to operate simultaneously, and then complete the simultaneous stamping and demolding operations at four stations. Moreover, the central seat 11, as a connecting piece, can be quickly fixed to the stamping plate 13 through the docking component, and the specified stamping plate 13 can be quickly disassembled and replaced.

[0030] It should be noted that the upper die 14, the outer frame 6 of the lower die, and the base 23 of the lower die of this device are all arranged on the same vertical line. The outer frame 6 of the lower die and the base 23 of the lower die form a complete lower die.

[0031] Specifically, refer to Figure 1-2 , a first electric cylinder 5 is fixed at the middle position above the top plate 2, and the telescopic end of the first electric cylinder 5 is fixed to the center seat 11.
