Woo Comerce- Upsells displaying randomly

The theme I am using is called Bonfire.

On the single-product.php template, I want to be able to call the upsells of a product. Is there something like

<?php woocommerce_related_products( 4, 4, 'rand' ); ?> I can do. Right now I have

<?php get_header('shop'); ?>

<?php do_action('woocommerce_before_main_content'); ?>

<div class="inner-container clearfix">

	<!--<div class="page-single page-sidebar">-->

	<div id="product" class="clearfix">

	<?php custom_woocommerce_single_product_content(); ?>

	</div>

	<div id="sidebar">

	<?php dynamic_sidebar('woo-single-sidebar'); ?>

	</div>

</div>
<!-- Start UpSells Section-->
<?php
/**
 * Up-sells
 */

global $product;
$upsells = $product->get_upsells();
if (sizeof($upsells)==0) return;
?>
<div class="upsellss products">
	<h2><?php _e('Other Jugz Models&hellip;', 'woocommerce') ?></h2>
	<?php
	$args = array(
		'post_type'	=> 'product',
		'ignore_sticky_posts'	=> 1,
		'posts_per_page' => 3,
		'orderby' => 'rand',
		'post__in' => $upsells
	);
	query_posts($args);
	woocommerce_get_template_part( 'loop', 'shop' );
	wp_reset_query();
	?>
</div>

<!--Stop UpSells Section -->
<div class="product-tabs">
	<?php do_action('woocommerce_after_single_product_summary'); ?>

</div>

<?php woocommerce_related_products( 4, 4, 'rand' ); ?>

<?php get_footer('shop'); ?>

So as you can see on https://www.jugzstore.com/shop/gloss-black-grey-polarized-5059d/, when you refresh the page, the Other Jugz Models (3 products) randomly change. How do I get it just to show the upsells attached to the product posts?

Thank you in advanced.
