[0004] In the above patent, a pneumatic method is adopted to control the descent and ascent of the upper mold, and the movement of the upper mold is limited by guide columns and guide holes.

[0014] The present invention provides an injection mold for producing a dining table for a recreational vehicle. It has the following beneficial effects: (1) The injection mold used for the production of RV dining tables drives the upper mold and the injection tube to deviate a short distance and not align with the lower mold by moving the placement plate, thereby preventing the liquid plastic remaining in the injection tube from directly dripping onto the top of the molded plastic product. By preventing the liquid plastic from dripping onto the top of the molded plastic product, the surface quality and appearance of the molded plastic product can be improved. If the liquid plastic drips onto the surface of the molded plastic product during the demolding process, it will cause defects or unevenness on the surface of the molded plastic product, affecting the aesthetics of the plastic product and the effect of subsequent spraying processing. At the same time, the No. 1 L-shaped rod moves slowly, causing the support rod and the stabilizing frame to move slowly, and the support rod moves slowly, causing the placement plate and the upper mold to move slowly. The upper mold moves slowly to align with the lower mold, allowing the operator to have enough time to ensure that the upper mold and the lower mold can be accurately aligned to avoid offset or incomplete alignment.

[0015] (2) The injection mold used for the production of RV dining tables moves toward the direction of the upper mold through the movement of the sliding rod to contact the bottom of the placement plate and provide auxiliary support for the placement plate and the upper mold. The auxiliary support can make the subsequent maintenance and replacement of the upper mold more convenient. The operator can perform these operations under safe and stable conditions to avoid accidents caused by the instability of the upper mold and protect the safety of the operator. At the same time, the arc block moves and hits the fixed plate to generate vibration. The vibration of the arc block drives the support frame to vibrate. The vibration of the support frame drives the edge of the placement plate to resonate together. There may be overflowed plastic left on the bottom edge of the placement plate. The residue can be loosened from the placement plate and made to fall through slight vibration to prevent the residue from contaminating the next batch of injection molded products.

[0016] (3) The injection mold used for the production of RV dining tables is deformed by the rubber block inside the guide tube being squeezed by the quantitative release agent at the bottom of the sealing frame. The deformation of the rubber block releases the seal of the guide tube. After the seal of the guide tube is released, the quantitative release agent at the bottom of the sealing frame is sprayed onto the lower mold and the upper mold through the guide tube to facilitate the subsequent removal of the molded plastic product. After solidification, the liquid plastic will adhere to the surface of the upper and lower molds, making demolding difficult. Spraying the release agent can form a thin film before the upper and lower molds are closed, making it easier for the molded plastic product to be separated from the lower mold, thereby improving the demolding efficiency of the molded plastic product. At the same time, excessive release agent will cause quality problems such as uneven surface and increased residues of the molded plastic product. Quantitative and precise spraying can ensure the integrity of the molded plastic product. BRIEF DESCRIPTION OF THE DRAWINGS
