Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to automobile connector processing equipment. Background Art

[0002] Currently, most of the automotive connectors on the market are manufactured by injection molding, where the heated and melted plastic is injected into the mold cavity by an injection molding machine under high pressure. After cooling and solidification, the automotive connector molded product is obtained. However, the cooling effect of existing injection molds is poor. In the actual production process, it is difficult to quickly cool down the automotive connector after injection molding. During demolding, the molded product cannot be quickly separated from the mold, which affects the processing efficiency. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile connector processing equipment, comprising an upper mold and a lower mold, the top of the lower mold is provided with a groove, an injection molding box is movably installed in the groove, a cooling cavity is provided between the side of the injection molding box and the inner wall of the groove, a coolant tank and a cavity are provided inside the lower mold, the cavity is located above the coolant tank, a pressure plate is slidably installed on the inner wall of the cavity, a push rod is provided at the top of the pressure plate, a push rod is provided at one end of the push rod away from the pressure plate, the upper end of the push rod extends into the groove and abuts against the bottom end of the injection molding box, a liquid inlet pipe is provided between the right side of the coolant tank and the cooling cavity, a branch pipe is provided on the liquid inlet pipe, the branch pipe is communicated with the inside of the cavity, and a liquid outlet pipe is provided between the left side of the coolant tank and the cooling cavity.

[0005] The following improvements are made in the present application: a limit plate and a return spring are sleeved on the push rod, one end of the return spring is connected to the bottom end of the limit plate, and the other end is connected to the outer wall of the cavity. Through the coordination between the limit plate and the return spring, when the upper mold is pressed down, the push rod is driven downward by the push rod, and the limit plate moves downward with the push rod and compresses the return spring. After the injection molding is completed, the limit plate returns to its position under the action of elastic force, driving the push rod upward, and then the injection molding box is ejected by the push rod, which is convenient for demoulding.

[0006] The following improvement is made in the solution of the present application: a liquid outlet is provided at the end of the branch pipe, a liquid inlet is provided on the cavity, and the liquid inlet is communicated with the liquid outlet.

[0007] The following improvements are made in the present application: a slide groove is provided on the cavity, a guide rod is provided in the slide groove, a fixed plate and a blocking spring are sleeved on the guide rod, the bottom end of the fixed plate is fixedly connected to the outer wall of the cavity, and a stopper is connected to the end of the guide rod away from the cavity, and the stopper cooperates with the liquid outlet. In the initial state, the stopper presses against the liquid outlet to form a closure, and when the pressure plate moves downward, the pressure in the space above the cavity and the pressure plate decreases, so that the guide rod drives the stopper to move to one side of the cavity, the branch pipe is connected to the cavity, and the coolant flows into the cavity.

[0008] The following improvements are made in the present application: a through hole is provided on the pressing plate, and a channel is provided between the bottom end of the cavity and the coolant tank. The coolant flowing into the cavity through the branch pipe can flow back into the coolant tank through the through hole and the channel for reuse.

[0009] The following improvements are made in the solution of the present application: a hydraulic mechanism is fixedly installed on the top of the upper mold, and an injection cavity matching the upper mold is provided in the injection box.

[0010] Compared with the prior art, the utility model provides an automobile connector processing equipment, which has the following beneficial effects:

[0011] The utility model drives the pressing plate to move downward by pressing down the upper mold, so that the pressure of the space between the cavity and the pressing plate is reduced, and the coolant is sucked out through the branch pipe and the liquid inlet pipe, and a part of it enters the cooling cavity outside the injection molding box through the liquid inlet pipe, thereby cooling the molded product, accelerating the cooling and temperature reduction, facilitating the rapid separation between the molded product and the injection molding box, and improving the processing efficiency.
