For this reason, an injection mold having a function of assisting mold release is required.
Disclosure of Invention
An object of the utility model is to provide an injection mold with help drawing of patterns function, this injection mold can realize not spouting the release agent and just can guarantee the smooth drawing of patterns of product.
The technical scheme of the utility model lies in: the utility model provides an injection mold with help drawing of patterns function, includes die carrier and lower die carrier, it is connected with matched with cope match-plate pattern and lower bolster to go up die carrier and lower die carrier correspondence, be provided with the die cavity that is used for placeeing the skylight between cope match-plate pattern and the lower bolster, be provided with the gating system that is used for the skylight to bordure between cope match-plate pattern and the lower bolster, still be provided with fluororesin drawing of patterns coating on the die joint of cope match-plate pattern and lower bolster respectively, be provided with the absorption positioning mechanism in skylight and accomplish the locking mechanism of cope match-plate pattern and lower bolster locking on the lower bolster.
Furthermore, the gating system comprises a covered edge pouring gate which is arranged between the upper template and the lower template and is positioned at the rear part of the cavity, and a mixing head connected with the covered edge pouring gate is arranged on the upper template.
Furthermore, the adsorption positioning mechanism comprises vacuum chucks arranged on the lower template and located at four corners of the cavity, and vacuum equipment connected with the vacuum chucks is arranged on the lower die frame.
Furthermore, the locking mechanism comprises fixing frames at two sides and front and back sides of the lower template, an air cylinder is horizontally arranged on the fixing frame, a positioning end is arranged at the end part of a telescopic rod of the air cylinder, and positioning grooves are correspondingly arranged at the two sides and the front and back sides of the upper template.
Furthermore, cooling water channels are arranged on the upper template and the lower template, the upper template and the lower template are respectively connected with the corresponding upper die frame and the corresponding lower die frame through support columns, and a forklift ring for carrying is further arranged on the upper die frame.
Compared with the prior art, the utility model has the advantages of it is following: the injection mold can ensure that the product can be smoothly demoulded and the surface is smooth without spraying a demoulding agent, and the production efficiency of the PU skylight mold injection is greatly improved; meanwhile, the product demoulding effect after the 300 moulds are continuously punched is completely consistent with that of the first mould, and the appearance of the product is not influenced.

Detailed Description
In order to make the aforementioned features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 5
The utility model provides an injection mold with help drawing of patterns function, includes die carrier 1 and lower die carrier 2, it is connected with matched with cope match-plate pattern 3 and lower bolster 4 to go up die carrier and lower die carrier correspondence, be provided with the die cavity 5 that is used for placeeing the skylight between cope match-plate pattern and the lower bolster, be provided with the gating system that is used for the skylight to bordure between cope match-plate pattern and the lower bolster, still be provided with fluororesin drawing of patterns coating on the die joint of cope match-plate pattern and lower bolster respectively, be provided with the absorption positioning mechanism in skylight and accomplish the locking mechanism of cope match-plate pattern and lower bolster locking on the lower bolster.
In this embodiment, in order to complete the edge-covering pouring, the pouring system includes an edge-covering pouring gate 6 disposed between the upper mold plate and the lower mold plate and located at the rear portion of the cavity, and the upper mold plate is provided with a mixing head 7 connected to the edge-covering pouring gate.
In this embodiment, adsorb positioning mechanism is including setting up on the lower bolster and being located the vacuum chuck 8 of four corners of die cavity, be provided with the vacuum apparatus 9 that is connected with vacuum chuck on the lower die carrier to when placing on the die cavity of lower bolster in the skylight, adsorb the skylight through the sucking disc and live.
In this embodiment, the locking mechanism includes a fixing frame 10 on two sides and front and back sides of the lower template, an air cylinder 18 is horizontally disposed on the fixing frame, a positioning end 11 is disposed at an end of a telescopic rod of the air cylinder, and positioning grooves 12 are correspondingly disposed on two sides and front and back sides of the upper template, so that locking of the upper template and the lower template after mold closing is completed.
In this embodiment, be provided with cooling water course 13 on cope match-plate pattern and the lower bolster, cope match-plate pattern and lower bolster are connected with corresponding upper die carrier, lower die carrier through support column 14 respectively, still be provided with the fork truck ring 15 that is used for the transport on the upper die carrier, the upside that the cope match-plate pattern is located the die cavity in the morning is provided with fretwork portion 16 to reduce the consumptive material of cope match-plate pattern and reduce the heat absorption of cope match-plate pattern, help the mould cooling.
